The Year 2050-Reflection Of A Futurist Summary in English

Summary:

A remarkable feature of 2050 will be that most of the 1960 babies will still be alive because of a biomedical revolution that is underway. Death rules of different life-killing diseases have dropped considerably. This has become possible due to the availability of antibiotics, better health care, attention to diet, jogging, and exercise the effects in the United States are clear-cut and lasting. But increased longevity and improve health are like to have several drawbacks:

  • world population will be larger than it might have been
  • low birth rate and increased longevity combine to raise the average age of the population
  • A period of difficult social adjustment will be likely.

However, there is a really good chance that a huge increase in food production can come from such development as:

  • new plant varieties, obtained through genetic engineering which are photosynthetically efficient use less water and tend to be self-fertilizing,
  • improved uses of the ocean, including the domestication of seeing animals aquaculture and
  • tropical agriculture which will open to the world many billions of acres of land currently unusable.

Before nondepletable alternatives and commercially developed, new synthetic fuel industries for the conversion of coal into gaseous and liquid fuels and the extraction of petroleum of liquids from oil shale are likely to arise. Solar, geothermal, wind power, and fusion are electric-producing items. By the year 2050, we should be well along toward utilizing two virtually inexhaustible energy resources; solar electric power and nuclear power resources between now and 2050. They are (i) electronics, genetics, and psychology.

CHSE Odisha Class 12 Alternative English Solutions Unit 4 Text A: The Year 2050-Reflections of a Futurist

By the early in century machines will be available that perform better than human beings. In fact, genetics is a science about to become a technology. This technology will lead to the ability to ‘design’ plants and animals to perform human functions. In agriculture, scientists will be able to produce plants that have improved photosynthetic efficiency, minimum water requirements, self-fertilizing characteristics, and a desired spectrum of nutrient qualities. In mining, organisms will metabolize desired ones tells and thus concertable them for later ‘harvesting’.

In the production of pharmaceuticals, microorganisms will be used as factory workers to produce chemicals normally found only in natural body and plant processes. Finally, in medicine, scientists will intervene in the process by which genetic diseases such as sickle cell anemia. Tay Sachs disease and mongolism are passed from parents to their progeny to cure these diseases before conception. They will also address other diseases such as cancer or heart disease and even aging itself.  Of course, Psychology by 2050 will be ready to take off. The ‘trigger’ discovery will help us know how memory is recorded and retrieved.

It is not clear till now whether memory is chemical, electrical, or physical knowledge of sharing and retrieving of memory will improve education, persuasion, rehabilitation, personality development, and knowledge itself and open the huge and exciting possibility of expanding mental capacity closer to the limits of human potential. Perhaps by 2050, observers in the orbital city cloud follow the world food supply and predict harvest size and crop diseases. Many things can be controlled from the orbit. The boom – babies will face significant challenges in the years ahead.

Analytical Outlines:

Very Short Type Questions With Answer

Question 1.
What is Mean?
Answer :
When people talk about averages, they’re often referring to the mean, which is the arithmetic average of a set of scores. You have probably calculated the mean of a set of Psychology scores many times in the past. Every time you sum a set of scores and divide that sum by the total number of scores you have calculated the arithmetic mean of those scores.

Question 2.
What is the Median?
Answer :
The median is the middle score in a set of scores that have been ranked in numerical order. In cases where there are an even number of scores, the median lies between the two middle scores and is given the value of the midpoint between those scores. Of course, if the middle two scores in an even number of scores are the same, the median has the same value as the two scores themselves.

Question 3.
Range?
Answer :
The range is simply the difference between the highest and lowest scores in a distribution and is found by subtracting the lowest score from the highest score. This measure of variability gives the researcher only a limited amount of information, as data sets which are skewed towards a low score can have the same range as data sets which are skewed towards a high score, or those which cluster around some central score.

Question 4.
What is Variance?
Answer :
A more informative measure of variability is the variance, which represents the degree to which scores tend to vary from their mean. This tends to be more informative because, unlike the range, the variance takes into account every score in the data set. Technically speaking, the variance is the average of the squared deviations from the mean.
To calculate the variance for a set of quiz scores:

  • Find the mean score.
  • Find the deviation of each raw score from the mean. To do this,
  • Subtract the mean from each raw score. (Note that deviation scores will be negative for scores that are below the mean.) To check your calculations sum the deviation scores. This sum should be equal to zero.
  • Square the deviation scores: By squaring the scores, negative scores are made positive and extreme scores are given relatively more weight.
  • Find the sum of the squared deviation scores.
  • Divide the sum by the number of scores. This yields the average of the squared deviations from the mean, or the variance.

Question 5.
What is the Median?
Answer :
The median is the middle score in a set of scores that have been ranked in numerical order. In cases where their art an even number of scores, the median lies between the two middle scores and is given the value of the midpoint between those scores. Of course, if the middle two scores in an even number of scores are the same, the median has the same value as the two scores themselves.

There is no formula for quickly calculating the median Without doing some initial data analysis. Typically, when dealing with large data sets, researchers construct a frequency distribution representing all the scores in the data set. This allows time to use a formula to calculate each measure of central tendency using the information provided by the frequency distribution.

Unlike the mean, the median is a good measure of central tendency to use when describing a heavily skewed set of scores. Returning to our example from above, our student’s median test score would be 94%, which is a much better indication of the student’s overall performance.

Thus, the median is a better representation of the scores within a skewed data set than is the mean. In fact, the median is the best method of central tendency to use when describing skewed data.

Long Questions With Answers

Question 1.
What statistical use for psychology?
Answer :
Much of psychological research involves measuring observations of particular characteristics of either a population or a sample taken from a population. These measurements yield a set of values or scores, and this set represents the findings of the research or data. Often, it is impractical to completely measure, the characteristics of a given population, known as parameters, directly.

Thus, psychologists often focus on the characteristics of samples taken from a population. These characteristics are called statistics. The psychologist then uses these sample statistics to make inferences about population parameters.

In this section, we will focus on a type of statistics known as descriptive statistics. We will begin with an examination of three methods of describing a set of data using scores that seem to be typical of those found in the set. We will then look at three methods of describing how scores within the set vary from these typical scores.

Question 2.
Measures of Central Tendency.
Answer :
Often, data tends to group itself around some central value. This value may, in turn, be used to describe or represent the data set as a whole. Methods of determining these central values are called measures of central tendency. There are three main measures of central tendency used by psychologists. They are the mean, the median, and the mode.

Mean :
When people talk about averages, they’re often referring to the mean, which is the arithmetic average of a set of scores. You have probably calculated the mean of a set of Psychology scores many times in the past. Every time you sum a set of scores and divide that sum by the total number of scores you have calculated the arithmetic mean of those scores.

As you probably know from experience, the mean can be affected by extreme scores. For example, if a student were to receive five test marks over 90% and one test mark less than 20%, (let us say marks of 98%, 96%, 94%, 94%, 92%, and 18%), the mean of – 497 – the test scores would be (98 + 96 + 94 + 94 + 92 +18) / 6 = 82.

Obviously, the mean, in this case, has been pulled in the direction of the score of under 20%. For this reason, the mean can be a very, misleading description of a set of scores with a heavily skewed distribution.

Median :
The median is the middle score in a set of scores that have been ranked in numerical order. In cases where there are an even number of scores, the median lies between the two middle scores and is given the value of the midpoint between those scores. Of course, if the middle two scores in an even number of scores are the same, the median has the same value as the two scores themselves.

There is no, the formula for quickly calculating the median without doing some initial data analysis. Typically, when dealing with large data sets, researchers construct a frequency distribution representing all the scores in the data set. This allows them to use a formula to calculate each measure of central tendency using the information provided by the frequency distribution.

Unlike the mean, the median is a good measure of central tendency to use when describing a heavily skewed set of scores. Returning to our example from above, our student’s median test score would be 94%, which is a much better indication of the student’s overall performance. Thus, the median is a better representation of the scores within a skewed data set than is the mean. In fact, the median is the best method of central tendency to use when describing skewed data.

Mode :
The mode is simply the most frequently occurring score in a data set. Returning once again to the test scores of our sample student, the mode for this data set is would be 94%, as it occurs twice within the data set. If two scores occur equally often within a data set, the set has two modes and is termed bimodal. Any data set that has two or more modes can be referred to as multimodal.

Like the median, there is no formula for calculating the mode without conducting at least some preliminary data analysis. For small data sets the mode may simply be determined by comparing the number of times the most popular scores appear in the set.
Measures of Variability
Almost all data sets demonstrate Some degree of variability. In other words, data sets usually contain scores that differ from one another. Only under very rare circumstances to researchers encounter data sets that have no variability.

Needless to $ say, of the few sets of data that demonstrate no variability, fewer still will be of any interest to psychological researchers. The truly interesting observations are those of characteristics that vary within a population or sample. This variability cannot be captured or shown by measures of central tendency.

For. example, if two data sets have the same mean, there is no guarantee that the two – 498 – sets are very similar at all. What is needed are measures of variability which allow the researcher to determine the degree of variation within a population or sample, and thus to determine just how representative a particular score is of the data set as a whole.

This in turn allows the researcher to determine the scope and validity of any generalizations he or she wishes to make based on his or her observations. The measures of variability used by | researchers include the range, the variance, and the standard deviation.

Question 3.
What is Range?
Answer :
The range is simply the difference between the highest and lowest scores in a
distribution, and is found by subtracting the lowest score from the highest score. This measure of variability gives the researcher only a limited amount of information, as data sets which are skewed towards a low score can have the same range as data sets which are skewed towards a high score, or those which cluster around some central score.

The range is, however, useful as a rough guide to the variability demonstrated by a data set, as it tells the researcher how a particular score compares to the highest and lowest scores within a data set. For example, a student might find it useful to know whether his or her score was near the best or worst on an exam.

Question 4.
What is Variance?
Answer :
A more informative measure of variability is the variance, which represents the degree to which scores tend to vary from their mean. This tends to be more informative because, unlike the range, the variance takes into account every score in the data set. Technically speaking, the variance is the average of the squared deviations from the mean.

  • Find the sum of the squared deviation scores.
  • Divide the sum by the number of scores. This yields the average of the squared deviations from the mean, or the variance.

Question 5.
What is Standard Deviation?
Answer:
More informative still is the standard deviation, which is simply the square root of the variance. You may be asking yourself why not simply use the variance ?’ One reason is that, unlike the variance, the standard deviation is in the same units as the raw scores themselves. This is what makes the standard deviation more meaningful. For example, it would make more sense to discuss the variability of a. set of IQ scores in IQ points than in squared IQ points.

Long Answer Questions With Answers

Question 1:
Discuss the life philosophy of Gandhi.
Answer:
Gandhi enunciated integral philosophy of fife. He was a naturalist, an idealist,
individualist in one. His ‘Experiment on Truth’ was the outcome of his experience and prominent philosophical activities are his concept of God, truth, doctrines of morality, non¬violence, satyagraha, labor, equality, citizenship, brotherhood of man His life was concerned with:

  • His concept of truth.
  • His concept of karma.
  • His concept of non-violence.
  • His concept of satyagraha.
  • His idea of centralization.
  • His idea of machine.
  • His concept of the village.
  • His news of morality.

1) His concept of truth – Gandhiji believed in truth to be the ultimate reality and God can be realized through truth. God is truth, and truth is God. He said truth is manifested both externally and it is expressed through the voice of God. He was the pioneer of truth and non¬violence and conquered the brutal force. One can realise god through truth.

2) His concept of Karma – In Gita, there is view on life and karma. Gandhiji was deeply influenced by Gita for a religious dedication to the service of man. Service of humanity is God. Religion is not a part from human activity. Action takes its origin from Brahma and Brahma is present in all kinds of sacrifice of service. To Gandhi, society and social service are an integral part of life and they are sacred activities.

3) His concept of non-violence – Non-violence of Gandhi was equivalent to love. His concept of non-violence retained deeply in Indian spirituality. The concept ofAhimsa or non-violence of Gandhi was a means and that an end. Man is the end of his material, mental and moral well-being and growth.

4) His concept of Satyagraha – Gandhiji’s concept of Satyagraha was dynamic aspect of non-violence and a tool that created a human context for social conflict. Truth is the end and non-violence is the means to human activities.The term ‘ Satyagraha’ is derived from the Gujarati word ‘agrapha’ which means firmness. For Gandhiji satyagraha is dynamic quality of non-violence. Satyagraha for Gandhiji’s way a truth force for acting socially and humanely.

5) His idea of decentralization – Gandhiji was against concentration of power and individualism of capitalism. He wished a kind of society where economic and social structure of decentralization on the basis of industry and agriculture. This is the productivity aim of education.

6) His idea of machine – Gandhiji was not against the machine, but he did not want it to become the master of machine. He opposed strongly machines because it created unemployment and exploitation of the poor workers by capitalists and too much dependence on man on machine. So he suggested to limit the manufacture of machine and emphasized on cottage industry and handicrafts.

7) His concept of the village – To Gandhiji, village is a small group of people, consisting a unit of society. So the village should be self-governing. He considered that it should be self¬sufficient in the matter of its vital necessities of life like food, clothing and shelter. Secondly his village was not an agricultural community, there should be a balance between agriculture and the village industries. He desired to create agro-industrial community.

8) Gandhiji’s gramraj – Village self government was the opinion of Gandhi. His idea of Gram raj or village self government means it is a complete republic independent or its neighbours are independent with other necessaries. Thus, for every villages the first concern will be no caste and hopes to abandon untouchability and create a class less society.

9) His views on morality – To Gandhiji, the end of all knowledge is the development of morality. The society and individual progress through morality, purity in thought, speech and deeds. So a social foundation of truth and purity should be established through education. To him moral education is to be imparted in schools. Morality is the best virtue of humanity. By participation in games and sports discipline in thought and action is maintained.

Question 2:
Write a note on the Educational Philosophy of Gandhi.
Answer:
As a socio-political, reformer, educationist, idealist, naturalist, social leader and practical philosopher, Gandhiji father of the Nation, the apostle ofpeace and non-violence, the champion of Freedom movement led a scheme of education of India known as ‘Basic Education’. In another way it is known as “Nayee Talim”. His educational philosophy is the potent force for social reconstruction. To him true education is “An all round drawing out of the best in child and man” – body, mind and spirit. The chieftenents ofhis educational philosophy are as follows:

  • Education should be free and compulsory.
  • Craft centred education.
  • Self supporting education
  • Emphasis on mother tongue.
  • Child centredness.
  • Emphasis of education on non-violence.

1) Education should be free and compulsory : Gandhi advocated free and compulsory education for 7 to 14 years and wanted to combine primary education with secondary education called it English Less Matriculation Courses. To him democracy will become successful when education will be free and compulsory. It will develop love for creative work. As India is a poor land and 60 % of population are below the poverty line so education should be free and compulsory for them.

2) Craft centred education : He believed in the principle of learning by doing’ of John Dewey. The basic education aimed at providing education on crafts. He introduced basic crafts like spinning and weaving, carpentry and agriculture. Introduction of crafts evoke the spirit of love for work and teach them the dignity of labour. To him the whole educative process be imparted through handicraft. They will leam the motto “work is worship”. It will develop the dignity of labour.

3) Self-supporting education: Gandhiji knew that India is a poor state and it cannot afford to educate the millions. So Gandhi suggested education to be self supporting. The concept of “Karma Yoga” and dignity of labour will help in the intellectual development. So the child should pay labour partly by binding a gap between education and life drawing upon the cultural, social and vocational potentialities. It is a measure of social reconstruction.

4) Emphasis on mother tongue: Gandhi emphasized mother tongue as the medium of instruction. To him the English system of education hinders understanding and clarity of ideas. By mother tongue, the children can express their views clearly and understand others and this would build sound foundation of education.

5) Child centredness: Child-centredness is an important feature of Basic Education which means the children should be taught to the needs, interests, and capacities of children. So the curriculum and the method of teaching are to be developed to the capacities of learners. Different crafts and subjects to be included in the curriculum to meet individual differences.

6) Education based on non-violence: A unique feature of Gandhiji’s education philosophy was the application of the law of non-violence. He wanted to build a classless society and elimination of exploitation. By the scheme of non-violence and peace, he conquered the heart of brutal forces. So his education of philosophy is based on non-violence. He wanted to create a generation that should believe in non-violence.

Question 3:
What should be the aims, curriculum and methods of teaching of Basic
Education?
Answer:
M. K. Gandhi is called an idealist, a realist, a spiritual person in one. He advocated his philosophy of education and put stress on religious education. The main aims of this philosophy are as follows :

  • The utilitarian aim.
  • The cultural aim.
  • Harmonious development aim.
  • Complete living aim.
  • Character building aim.

1. The utilitarian aims : To fulfill this aim, the basic needs of human life like food, clothing and shelter and self-supporting to be imparted. The self-supporting aspects aimed at self-sufficient and education to meet one’s expenses. It is otherwise known as ‘Bread and Butter Aims ’ of education.

2. The cultural aims: Culture is essential to refine one’s personality.One should have the qualities of mind which should be reflected in one’s own conduct. Such aims helps in the transmission of culture.

3. Harmonious development aim: To Gandhi, education means “An all round draw ing out of the best in child and man, with body, mind and spirit”. To Gandhi, harmonious development means – innate and acquired powers development from social to intellectual. Basic education helps with all round development of personality of the individuals.

4. Complete living aims: To Gandhi, life is very complex. So he formulated a scheme of education which would fit the children to later life and a child to be prepared for complete living. He should learn how to support his living, social adjustment, occupation and self¬reliance.

5. Character building aims: Character building was the chief aim of basic education. To him character is the expression ofthe w’hole personality including the ethical and spiritual aspects. One should subordinate his own interest to the greater interest ofthe society, cooperate his fellow being about a new social order. Such a person is really a man of character. In his aims of education, Gandhi emphasis the building of character.

The individual character will influence the national character.
i)Curriculum: Gandhi emphasized on child centred curriculum. Education should be related to the environment of the child. He opposed English as the medium of instruction and mother tongue as the medium of instruction up to the level of matriculation. To him English hinders the clarity of thought and put a check on self-expression.My mother tongue, one can express his view correctly and understand others. It also helps in the development of nationalism and patriotism
He introduced craft as a part of curriculum and the whole process of education should be imparted through some handicrafts.
ii) Craft: Education should be given through the medium of some craft on productive work. So different handicrafts like weaving, spinning, carpentry, earthen pot building etc.
iii) Activity centred: The teaching of various subjects should be emphasized. Teaching of craft will be the center point and the teaching of all subjects should be related to craft.The co-related teaching methods are to be employed.
iv) Mother tongue: Mother tongue should be medium of instruction. It will help the children for clear expression and clear understanding, develop patriotism and nationalism.
v) Religious and moral education: For the development of personality, character religions and moral education is to be given. All should respect to all religions. Ethics of all religions is to be taught as a part of education. To Gandhi there is need of moral leaders in free India and building modem India.

Question 4:
Discuss the essential features of Basic Education. Explain the gift of Basic education to education.
Answer:
The essential features of Basic education include:

  • Free and compulsory education.
  • Purposeful activity-centred education.
  • Emphasis on mother tongue.
  • Self-supporting education.
  • Primary importance for village.
  • New cooperative regime.
  • Dignity of labor.
  • Co-operative work.
  • Integrated teaching.
  • Educates body, mind, and spirit.

1. Free and compulsory education: Basic Education implies a free and compulsory education for all children between the age of 7 to 14 years. It will reduce the disparity among the children.

2. Purposeful activity centred education: Basic Education centers round some purposeful activity or useful and productive craft training which supports self supporting aims of education.

3. Mother tongue: The medium of instruction should be mother tongue of the child. By this the child can express his views fluently and understand others’ views. It also inculcates the spirit of nationalism and patriotism.

4. Self-supporting: Basic Education is aimed at self-supporting. It followed the principles of learning by doing. They earn from their craft work as well, so as to cover their expenses. Thus craft has both educational and economic value.

5. Primary importance for the village: Basic education was primarily devised for the village. Gandhiji say, “In discussing the question of primary education, I have neither to deliberately confirmed myself to the village, as it is to villages that the bulk of Indians population resides’. To tackle successfully the question of village is to solve the problem for the cities also.

6. New cooperative regime: Basic education aims at bringing about a new cooperative regime in place of the present in-human regime based on exploitation and violent forces.

7. Dignity of labor: Basic education curriculum inculcates the virtue of dignity of labor, a keen sense of discipline, and a great sense of responsibility. Labour-centred education reduces disparity among pupils. It helps with self-employment.

8. Cooperative work: In the scheme of Basic education both the teachers and pupils work for community development and social progress.

9. Integrated teaching: In Basic education, all the subjects are taught in an integrated way. All the instructions are co-related. It seeks to develop the child as a whole. The child is taught with co-related teaching methods of all subjects like math, general science, social sciences, language, drawing and paintings etc. It helps the harmonious development of the child.

10. Educates body, mind, and spirit: Basic education is meant to educate the body, mind and spirit with an unique relation among them. It seeks to develop the child as a whole.

Question 5:
Discuss the causes of downfall of Basic education.
Answer:
Inspite of the merits of Basic education, the scheme was criticised by the richer classes, educationists and suffer from a number of limitations. After the death of Gandhiji the scheme was given a death-blow. The most important reasons of the failure of Basic Education are as follows :

  • The Unclear Concept.
  • Emphasis on Idealistic view.
  • Emphasis on Economic aspects.
  • Compact Area approach. ‘
  • Absence of Text Books.
  • Lack of Trained Skilled Teachers and Textbooks.
  • Faculty timetable.
  • Costliness of Basic Education.
  • Opposition of Traditionalists.
  • Matriculation of Minus English.
  • Lack of Research.

1) The Unclear Concept: In that period most of the educationists the common people, education administrators as well were not clear about the concept of Basic Education. They were confused of craft education and mechanical education. The common people could understand nothing. In that period, there was no provision of propagation and no mass media system to highlight the program. So the concept of the scheme could not touch the common people and got failure.

2. Emphasis on Idealistic Approach: The scheme laid stress on some idealistic practices like manual work. Such scheme of education was not accepted by the British and the intellectuals because they educated people do not appreciate that their children could do any manual labour. They sent their children to public schools and English medium schools. So the confusion is created.

3. Emphasis on Economic Aspects: In Basic Education, too much emphasis was given on economic aspect. The craft centredness was not accepted by the intellectuals as well as educationists. The productivity activity of self supporting aspect exploits the child labour and craft work puts emphasis on economic aspect. The students become money minded. The guardians felt that their children were turned into laborers, so they opposed the basic ideals of craft.

4. Compact Area Approach: Basic schools were opened in some specific areas, especially in rural areas but not in town areas. The scheme was worked out in a limited area on an experimental basis. So compact area approach was a major cause of the failure of such education system.

5. Absence of Text Books: Basic scheme of education emphasized on craft education. It was a mechanical education. Text books were riot emphasized and no text book was prepared as there were no writers to prepare textbooks on craft training. It was another major causes of the downfall of Basic Education.

6. Lack of Qualified teachers: It was a new type of education like craft. The traditional teachers failed to understand the new pattern of education and the curriculum prepared by Dr. Jakir Hussain. Qualified trained teachers were not available as it was mechanical teaching. There was no provision of teachers’ training. So lack of qualified trained teachers, the Basic Scheme of Education led its downfall.

7. Faculty Time Table: In Basic Education much more was invested or devoted for craft work and other subjects were neglected. In a Basic School 2/3rd. of the time was utilized in craft work. On the timetable, academic subjects were taught after craft work. So academic subjects were neglected. Agricultural students become tired to their academic work. So the faulty timetable was an obstacle of spreading Basic Education.

8. Costliness of Basic Education: As Basic Education needed equipment, so more initial cost was required to purchase craft equipment. There were no funds to meet such expenses and the Govt, could not afford it so it led its downfall.

9. Opposition of Traditionalists: The dream of Gandhi to build a classless society was strongly opposed by the higher class people. So the traditionalists and conservatives were afraid that the new social order would upset their position and so they strongly opposed the system of education.

10. Matriculation Minus English Course: Gandhiji emphasized that English should not be taught to the students in matriculation stages. But the richer classes opposed this and did not prefer to admit their children in such a school. So the strength of the school reduced day by day.

11. Lack of Research: No research activities were encouraged and no research centers were set up. So lack of research, newer methods of teaching, and techniques the Basic Scheme of Education led its downfall.

One shared equally by the people. Pandit Nilakantha Das emphasized classless society education. The people of Odisha are poor and they cannot afford for the education of their children. So Gopabandhu proposed an education that should be ideal, forced, and inexpensive. In 1909 he set up a School at Satyabadi named as Open Air Schooling based on the ideals of Gopabandhu.

In the community dinner in his hostel, every day, high or low sit together and take meals.

To him, women are the wealth of the family as well as the wealth of the nation. They are the Goddess of family life. If women are educated, they will take care of their children.

7. Mother tongue as the Medium of Instruction – Gopabandhu emphasized on the importance of the mother tongue in the education of a child. It is essential to develop his mental powers.

Question 8:
Explain, the causes of downfall of Open Air Schooling or Satyabadi Vana Vidyalaya.
Answer:
Like the downfall of Basic Education of Gandhi, for some reasons Satyabadi Vana Vidyalaya led its downfall. The chief causes are:

  • Lack of local support and unclear concept.
  • Economic condition.
  • Lack of help of the Govt.
  • Participation of Gopabandhu in Indian National Movement.
  • The death of Utkalmani.

1. Lack of local support and unclear concept – Satyabadi Vana Vidyalaya was surrounded by conservative villages. Conservative people and Brahmin society. Such conservatives did not appreciate the idealistic education system of Gopabandhu. Pandit Nilakantha Das wanted to build a classless society education which was a stroke to the conservatives.

The conservatives opposed this and they do not like to read their children with other backward-class children. They wanted to continue the superstitions.Lack of local support the enrolment of children is reduced.To oppose Gopabandhu’s system of education in 1912 on March 22, the conservatives fired the school and the main property of school library was destroyed. Such an incident shook the strength of the school.

2. Non-cooperation of the Govt.: It was not a traditional education system nor followed the British system of education and opposed the older beliefs, superstitions and conservatism. It is filled with idealism, patriotism, nationalism and social service programs.It aimed at creating leader for the state. So the British opposed it. No Govt, grant lias come and the application for Govt. Recognition was canceled. The school was transferred under Calcutta University in 1916 and then to Patna University in 1917, but it could not get the Govt. help.

3. Economic Condition : The third cause of the downfall of Open Air Schooling was the economic condition of the school. In 1921 Vana Vidyalaya was transferred into a National School. But the Govt, grant only two hundred rupees per year was refused and cut off very relationship from Patna University. In 1923, it turned to a National College and become autonomous. But it did not exist long. It suffered from the financial crisis. The teachers demanded to merge the college with the University. For this Gopabandhu remained away from the college. But the colleagues failed to continue the college for which it led its downfall.

4. Participation in Non-cooperation Movement: In 1920, Utkalamani joined in the Non-cooperation movement. He invested all his time and resources in the Freedom struggle. He found no time and resources to invest in groove school. Thus, the school led its downfall

5. The Death of Utkalamani: The day before the World famous Car Festival on June 17, 1928, Gopabandhu died in an immature death. The glorious chapter of Odia’s history’ came to an end. The next generation did not give any importance to the institution and just five years after the death of Utkalamani, the other Satyabadi Panchasakhas died one after another, the school was neglected and led its downfall.

Question 10:
Discuss the philosophical thoughts of Rousseau.
Answer:
Rousseau’s philosophical thoughts are related to Naturalism and Negative Education.

1) His Naturalism
a) God has made all humans good but when they come in contact with society they become spoiled. In order to change them again into good, we should bring them back to nature.
b) In the beginning of human civilization, man was happy and good, but now he is unhappy. If he goes back to nature, he will again be happy and good. Thus, a child be educated and developed according to his natural tendencies. Society and school has no role to play in the process.
c) He did not like old values and traditions of the society. According to him, social relations can be brought about by destroying these values.
d) There are three main forms of naturalism such as Social, Psychological and Physical. In his social naturalism, he devises education as a method to mold the society. He opined that we could not become a man and citizens at the same time. Out of two options, we should become a man only. Thus, the individuality of man is honored by him. Psychological naturalism meant that the child should be given chance to develop on the basis of his inner feeling and natural tendencies and experiences gained from contact with others are harmful and unnatural.By physical naturalism, Rousseau means that child should be given chance to come in contact with birds, animals, and other physical objects of nature and learn in the process. This learning will make him free from evils.
e) He opposes the organization of education in social foundations. Thus he opposed school/education in the formal sense and advocated an individual basis of education.
f) He opposed too all sorts of habit formation in the child. It is because this can make a child traditional.
Thus, Rousseau’s Naturalism is fully of many unnatural and impracticable ideas and he himself realized it but he put three ideas with such a force that is influenced not only the society of Europe but also the educational system of the period.

2) Negative Education
In the 17th. century, Europe, man was considered bad by nature. So efforts were made to change the nature of man by imparting religious education.
Rousseau went contrary to this believing infallibility of man and proposed the idea of Negative Education. By this education he means not teaching truth or virtues to a child but shielding his heart from evils and mind from errors. The feature of his negative education are given below:
a) Nothing against the interest, attitude on age of the child should be taught. He should be given full freedom to choose his own curriculum.
b) The education of a child should be based on his natural tendencies and stages of development by using different organs and senses of the child. Mind should be less taxed for the purpose. Mind should be inactive toll the child develops discretion power in him thus he emphasized, the training of senses by keeping the mind idle.
c) Child should be protected from outside environment to keep him alien to vices. In this way, there will not be any need to impart knowledge of virtues to the child. Virtues may be taught of the later stage of life.
d) The child should not be taught anything at all, especially from books. Small children should learn from nature itself.
e) Thus by Negative Education, Rousseau opposed not only the mental development of the individuals/child but he also opposed moral and spiritual development.

Question 13:
Discuss John Dewey’s contribution to educational thought and practice.
Answer:
John Dewey is one of the greatest educationists of the modem age. He has revolutionized the exponent of pragmatism.
Meaning of Education to John Dewey: John Dewey considered individuality as the aim of education. According to him, all education proceeds by the participation of the individual in social consciousness of the race. The educative process, according to John Dewey has two aspects – Psychological and Sociological because every individual is a psychological as well as social being. So no aspect can be neglected in the process of education.

  1.  Education as life: According to John Dewey education is a process of living. So the school experiences should have a resemblance with life outside the school and the school functions as a society in miniature form.
  2.  Education as Growth: Education is a continuous process that adds to child’s experience resulting in the growth and development of the child. It helps the child to grow to its full extent.
  3.  Education as Reconstruction of Experience: Every generation inherits certain experiences from its previous generation. These experiences are to be modified according to the changing situations through education.
  4. Education as a Social Process: Man is a social being and education socializes to human child. Right education helps the child make suitable adjustments with his social environment.John Dewey and Aims of Education: John Dewey is of the opinion that education process no aim beyond itself, it is its own end. There are no fixed aim of education to John Dewey.

Because, human life changes with the changes in time, place and situations and education should cater to the changing nature of human life. Education should therefore aim at cultivating a dynamic and adaptable mind in the child so that he can suitably adjust with his changing environment. Education should also create new value for the child. Education should aim at inculcating democratic values and attitudes in the child.

John Dewey and Curriculum: Curriculum according to John Dewey should reflect the child’s social life and social activities. It should be flexible, and changeable and it should take into consideration the child’s interests and educative experiences. As per example the curriculum at the primary stages should be based on the fourfold interests of the small child, interests in conservation and communication interests in inquiry interests in making change or construction and interest in artistic expression. Hence subjects like reading, writing, counting, handwork and drawing etc. are to be included at this stage.

The curriculum at higher students of education must have provisions for the environment and reorganization of past experiences. It just stimulates the learner to acquire new experiences and new ideas to they learned ones. John Dewey has also put emphasis on curriculum. This means each subject should be linked with the other and each should also related to the day life of the child.

John Dewey and Method of Teaching: John Dewey put emphasis on learning by doing. He stressed project method and this method is meant for the child. Earning was to be emphasized on teaching. The students should be free to carry on their whole planning and activity. Learning should be incidental and an outcome of the purposeful activity.

John Dewey and Discipline: John Dewey believed in the theory of free discipline and self-discipline. Discipline imposed from outside is directive with eyes of the John Dewey. Discipline should be social in character. The natural impulses of the child should be channelized in a socially desirable way. The main function of school discipline is to cultivate in the children’s social attitude, habits and ideal conduct through cooperative activity.

John Dewey and Role of the Teacher: In John Dewey’s system of education the child occupies the central position. The teacher is the friend, philosopher and guide of students. The teacher has to observe the pupil’s planning, encourage their activity and provide them the necessary opportunity and environment. John Dewey’s teacher is free to frame his own curriculum and carry on the administration ofhis own school.

Note:
Look at the difference between ‘have /has been ’ and ‘have/has gone ‘Has /have been’ means went and returned. But ‘has gone/have gone means went and not returned. The Present Perfect form of ‘go’ (has/have gone) is not used when the subject of the sentence is 7, we or you.’ The Present Perfect is used to refer to some happening in the past, for which the time of action is not given.

Question 1.
Determine the differentials in each of the following cases.
(i) y = x3 – 1
Solution:
y= x3 – 1
Then dy = 3x2 dx

(ii) y = sin2 x
Solution:
y = sin2 x
Then dy = 2 sin x cos x dx = sin 2x dx

(iii) y = \(\frac{1+\sqrt{x}}{1-\sqrt{x}}\)
Solution:
CHSE Odisha Class 12 Math Solutions Chapter 8 Application of Derivatives Ex 8(e) Q.1

(iv) z = cos 2t – 2 cot t
Solution:
z = cos 2t – 2 cot t
dz = (-2 sin 2t + 2 cosec2 t) dt

(v) r = \(\frac{4}{1+\sin \theta}\)
Solution:
r = \(\frac{4}{1+\sin \theta}\)
dz = \(\frac{-4 \cos \theta}{(1+\sin \theta)^2}\) . dθ
= \(-\frac{4 \cos \theta}{(1+\sin \theta)^2}\) dθ

(vi) x2y = 2
Solution:
⇒ y = \(\frac{2}{x^2}\)
dy = \(\frac{4}{x^3}\)

(vii) xy2 + yx2 = 1
Solution:
⇒ dx . y2 + x . 2y dy + dy . x2 + y . 2x dx = 0
⇒ (2 xy + x2) dy = – (y2 + 2xy) dx
⇒ dy = –\(\frac{y^2+2 x y}{x^2+2 x y}\)dx

Question 2.
Find δf and df when
(i) f(x) = 2x2 – 1, x = 1, δx = 0.02
Solution:
f(x) = 2x2 – 1, x = 1, δx = 0.02
Then δf = f(x + δx) – f(x)
= f(1.02) – f(1)
= 2 (1.02)2 – 1 – (2 – 1)
= 2.0808 – 2 = 0.0808
Again df = 4x dx
= 4 × 1 × 0.02 = 0.08

(ii) f(x) = √x, x = 16, δx = 0.3
Solution:
f(x) = √x, x = 16, δx = 0.3
CHSE Odisha Class 12 Math Solutions Chapter 8 Application of Derivatives Ex 8(e) Q.2

(iii) f(x) = (x + 1)3, x = 8, δx = 0.04
Solution:
f(x) = (x + 1)3, x = 8, δx = 0.04
δf = f(x + δx) – f(x)
= (9.04)3 – (8 +1)3
= (9.04)3 – 93 = 9.7632
Again df = 3(x + 1)2 dx = 3 × 92 × 0.04
= 243 × 0.04 = 9.72

(iv) f(x) = In (1 + x), x = 1, δx = 0.04
Solution:
f(x) = In (1 + x), x = 1, δx = 0.04
δf = f(x + 8x) – f(x)
= In (1 + x + 5x) – ln (1 + x)
= In (2.04) – In (2) = 0.0198
Again df = \(\frac{1}{1+x}\)dx = \(\frac{1}{2}\) × 0.04 = 0.02

Question 3.
Find approximate values of the following:
(i) \(\sqrt[3]{28}\)

(iii) \(\sqrt{48 \cdot 96}\)
Solution:
CHSE Odisha Class 12 Math Solutions Chapter 8 Application of Derivatives Ex 8(e) Q.3(3)

(iv) (1.99)7
Solution:
Let y = x7
Then dy = 7x6 dx
⇒ δy = 7x6 δx
⇒ (x + δx)7 – x7 = 7x6 δx
(x + δx)7 = x7 + 7x6 δx
Put x = 2 and δx = -0.01
Then (1.99)7 = 27 – 7 × 26 × 0.01
= 128 – 7 × 64 × 0.01
= 128 – 4.48 = 123.52

(v) 23.02
Solution:
Let y = 2x
Then dy = 2x In 2 dx
⇒ δy = 2x In 2 . δx
⇒ 2x + δx – 2x = 2x In 2 . δx
⇒ 2x + δx = 2x + 2x In 2 δx
Then 23.02 = 23 + 23 In 2 × 0.02
= 8 + 8 In 2 × 0.02 = 8.1109

(vi) sin 59°
Solution:
Let y = sin x
Then dy = cos x dx ⇒ δy = cos x . δx
⇒ sin (x + δx) – sin x = cos x × δx
⇒ sin (x + δx) = sin x + cos x × δx
Put x = 60°, δx = -1°
Then sin 59° = sin 60° + cos 60° x – \( \frac{\pi}{180} \)
\(\frac{\sqrt{3}}{2}\) – \(\frac{1}{2}\) × \(\frac{\pi}{180}\)
[ ∵ 1° = \(\frac{\pi}{180}\) radian = 0.85729

Question 5.
Find approximately the difference between the volumes of two cubes of sides 3 cm and 3.04 cm.
Solution:
Let V be the volume of a cube of side x cm.
Then V = x3 ⇒ dV = 3x2 dx
Here x = 3 cm and dx = (3.04 – 3) cm = 0.04 cm
Thus dV = 3 × 9 × 0.04 = 1.08 cm3
∴ Difference of two volumes is 1.08 cm3.

Question 6.
The height of a regular cone is 3 times the radius of its base. The radius of the base was wrongly measured to be 5 cm. whereas its true radius is 4.88 cm. Find the relative error in measuring the curved surface area of the cone.
Ans.
Consider a regular cone of height h and radius of its base x.
Then h = 3x.
If S is the area of the curved surface of the cone
then S = πxl
Where l is the slant height of the cone.
