Preface

In modern times, the future of every country depends on scientific

& technological development. India is a developing nation. Her future is

very much dependent on the progress of science & technology.

Therefore it’s in the fitness of things that science teaching and learning

should be given special attention. The scientific attitude which Indians

lack so much should be ingrained right from the childhood. Most

schools have no proper facilities. The same is in case of colleges of

teacher education. Science teachers should be thoroughly conversant

with the objectives of teaching, teaching process & in evaluation

method.

In evaluation system, now a day’s question banks are playing a

greater role. So I taught of making available to our students e-question

bank. My e-question bank to start with covers only second semester

physical science methods of teaching.

In future, e question bank will be made available to all the subjects

for the B.Ed course. However, suggestions for improvement are invited

from the readers and learners.

14. What are the merits and demerits of ‘Lecture Demonstration Method’? (2007)

Lecture Demonstration Method is considered to be a method superior to lecture method as it combines the

advantages of both the lecture method and the demonstration method. In this method both teacher and

taught are active participants in the process of teaching.

Merits:

All shortcomings of lecture method are removed.

All plus points of demonstration method are included.

The students get the clear picture of the topic.

It is a psychological method as students take active interest in the learning process.

It is useful for all students of varying abilities.

It is an economical method as compared to purely student-centred methods.

It leads the students from concrete experiences to abstract concepts.

It encourages students’ participation in learning.

It trains mental faculties such as power of observation, reasoning and drawing inferences.

Demerits:

The students do not get a chance to make use of apparatus independently.

They do not perform experiments, but only observe it. Each child is not able to observe and collect

proper data.

This method is not economically feasible.

It does not provide first-hand experience to the students.

It does not provide for individual differences. It caters to the needs of average students.

It does not develop manual and manipulative skills and cannot be a substitute for laboratory method.

If not very attentive, the students fail to observe minute details of the demonstration.

15. a. Write an essay on ’Guided-Discovery-Method’ of teaching physical science with reference to the

following:

i. Meaning

ii. Merits and Demerits

iii. Teacher-Role (2007) 10M

Ans:

Meaning:

This is systematic study of physical science under the guidance of physical science teacher.

J.S.Brunes, the originator of this method, “In this method the students discover new facts/knowledge in an

original manner as per their mental level, age, class and the other related facts. The facts are explained in a

manner by which they give a sense of new facts.”

It deals with the initial stages of development of research work conducted in connection with an

invention. The students are placed in the situation in which they are able to see how the faith of curious

inventor changes with facts related to new discoveries and inventions from time to time, how one principle

leads to the other or principle change into another.

Merits:

It makes students explore and help them becoming conversant with method of exploration.

It makes use of observation, thought and perception and develops these senses.

It helps in understanding social and scientific facts rather than learning them.

It helps in development of creative thinking.

It is helpful in achieving the high level objectives of knowledge and expression.

The students are able to discover new knowledge and try to retain it permanently.

They develop the qualities of analysis and synthesis.

They are able to understand how several changes can be brought about with the help of scientific

invention.

They are able to learn how one principle is converted to another and new principle is formed.

It is an interesting method for students.

The knowledge acquired by it is permanent.

Demerits:

It is not applicable to all subjects or topics.

The process of teaching is slow.

The students remain active but do not get a chance to become sharp.

It is more useful for brilliant students.

Role of Teacher:

He should be guide, friend and philosopher.

He should have thorough knowledge of subjects.

To conduct research or discovery equipment should be provided.

1. Explain the steps of demonstration method in physical science teaching. (2008)

Ans:

Planning and Preparation:

A great care should be taken by the teacher while planning and preparing demonstration method. He

should keep the following points in mind:

Subject matter.

Questions to be asked.

Apparatus required for the experiment.

The teacher should prepare his lesson plan which includes the principle to be explained, list of

experiments to be demonstrated and the type of questions to be asked from the students. The

apparatus should be arranged in a systematic order on the demonstration table.

Introduction of the lesson:

It is always considered more useful to introduce the lesson in a problematic way which would make

students realise the importance of the topic. A good experiment when carefully demonstrated is

likely to leave an everlasting impression on the young mind of the pupil. The teacher can introduce

the lesson by asking the questions related to that topic.

Presentation:

To make the demonstration interesting the teacher may not be rigid to remain within the prescribed

course rather he should make the demonstration as much as broad based as is possible. For widening

of his demonstration the teacher may think of various useful application of the principle. He can also

take example and illustrations from other allied branches of science.

The demonstration should be presented in a clear voice and the teacher should speak slowly with

correct pronunciation. He should avoid the use of any bombastic and ambiguous terms.

Performance of experiments:

The experiment should be presented by the teacher in a model way. He should work in a tidy, clean

and orderly manner while demonstrating an experiment. The following points should be kept in

mind:

Experiments should be simple and speedy.

The experiment should work and their results should be clear and striking.

Experiments be properly spaced throughout the lesson.

Keep some reserve apparatus on the demonstration table.

Black board summary:

A summary of the important results and principles be written on the blackboard. The blackboard

should be frequently used for drawing necessary sketches and diagrams. The blackboard summary

should be written in a neat, clean and legible way.

Supervision:

Students be asked to take the complete notes of the blackboard summary including the sketches and

diagrams drawn. The teacher should check the student notebook frequently, going to the seats of

the students.

3. What are the advantages and disadvantages of ‘Inductive approach’? (2008) 5M

Ans:

Advantages :

Develops scientific attitude.

Develops scientific thinking among the students.

Develops the skill of observation and critical thinking among the students.

Develops self-confidence and self-dependence.

Makes classroom instructions interesting.

A logical method based on – ‘Learning by doing’.

Generates the habit of intelligent thinking among the students.

It sustains students’ interest because they move from known to unknown.

Disadvantages:

A slow and lengthy method.

It is time consuming and laborious method.

It cannot be applied to all the topics of physical science.

Insufficient data leads to hasty and wrong conclusions.

Conclusions need to be verified by deductive approach.

This method can be used only when there are rules to be learnt.

16. b. critically analyse the advantages and disadvantages of following methods of teaching Physical

Science:

i. Guided discovery method

ii. Lecture cum demonstration method

iii. Individual instruction technique (2008) 10M

Ans:

Guided Discovery Method:

Advantages:

Student will gain first-hand experience.

Scientifically sound method.

Sort of training in discovery.

Self-study is possible.

It develops scientific attitude.

There will be a close relationship between teacher and pupil.

Disadvantages:

Well-equipped library and laboratory is not present in all the schools.

Lack of trained teachers.

Time bond is there in classroom.

Textbooks are not written to do discovery method.

Page 21: Physical Science e-Question bank

20 | P a g e

It becomes burden to the teacher.

Lecture-cum-demonstration Method:

Advantages:

It will make students absorb the knowledge and they will understand how an experiment is

conducted.

It is economical compared to Laboratory.

This is semi-psychological method.

It is a safe method to students.

No doubts will remain in the minds of the pupil as explanations are given time to time.

It saves time money and energy.

Retention will be more.

Disadvantages:

It is not purely scientific method.

It will not provide first-hand experience.

Process and product skill are partially developed.

This is a teacher centred method not a child centred one.

‘Learning by observation’ instead of ‘Learning by doing’.

Individual Instruction technique:

Advantages:

It provides for a learning environment that encourages the child to be motivated intrinsically.

It permits each child to progress at his own pace.

It helps each child to learn according to his interests, abilities and mode of learning.

It increases experiences for investigating by each child.

Disadvantages:

It requires a small class.

It needs increased time for the teacher to prepare and collect materials.

Materials for it are not available easily.

It is too costly compared to other methods.

It requires well-equipped science laboratory as well as other physical facilities.

How to make use of deductive approach? Explain with suitable example. (2008) 5M

Ans:

Deductive approach is opposite of Inductive approach. In this approach learner proceeds from

general to particular, from abstract to concrete. In this, facts are deduced or analysed by the application of

established formula or experimentation. In this case, the formula is accepted by the learner as a duly

established facts.

In this approach teacher announces the topic of the day and he also gives the relevant

formula/rule/ law/principle etc. The law/formula is also explained to the students with the help of some

examples, which are solved on the blackboard. From these, students get the idea of use or application of

concerned law/ principle/formula. Then the problems are given to the students who solve the problems

following the same method as explained to them earlier by the teacher. Students also memorise the results

for future application

Example:

Principle: Cooling is caused by evaporation.

Confirmation by application: it can be confirmed by numerous application, such as, by wearing wet clothes,

observing feeling after taking bath, by applying alcohol on your hand etc.

6. Write an essay on ‘Biographical method of Teaching’ with reference to its meaning, need, context of

use and merits. (2009)

Ans:

Biographical Method:

“Living, intelligent biography should connect, somehow, to the central concerns of civilisation. Ours is science-based one.”

- Andrew Marr The biographical method involves the study, use and collection of personal-life documents, stories,

accounts and narrations which describe turning point moments in individuals’ life. (Sir Issac Newton, the

apple falling on his head; Archimedes, bathing in a tub). The subject matter of the biographical method is

the life experiences of a person. When written in the first person, it is called an autobiography, life story or

life history. When written by another person, observing the life in question, it is called a Biography. This

method would rely upon the subjective verbal and written expressions of meaning given by the individuals

burg studied, these expressions being the windows into the inner life of the person.

Merits:

Life stories of Raman, Bose, Abdul Kalam, Faraday etc. would be really useful and interesting to

students.

It would enable the students to look into their life and perhaps dream big.

Like in the Historical Method, the link between science and values can be clearly brought out by the

teacher.

Experiences of the scientists could inspire students to reach great heights.

Skilful use examples from life stories show deficiencies in current research procedures and the new

dimensions that further analysis can add.

Need:

To enable the students to look into their life.

To link between science, society and values can be clearly brought out.

To inspire the students to reach great heights.

To enable the students for skilful use of examples from life stories.

Context of use:

Page 26: Physical Science e-Question bank

25 | P a g e

The Biographical method is used while narrating about the life of scientist which come across while

teaching Physical Science.

For Example: While dealing with ‘The Universe’ chapter we come across Galileo Galilei in IX standard

textbook.

Similarly, Sir Issac Newton, while dealing with Newton’s laws of motion in VIII standard.

9. What is ‘Inquiry Method’? Explain its merits and demerits. (2009) 5M

Ans:

Inquiry Method:

Inquiry method, as the word implies, relates to the inquiry about the topic. In this method the

student is an active learner. He subjects every information or fact to ruthless inquiry in order to know the

fact for himself and to test its validity, hi puts to rove the theories proposed by his teachers.

Merits:

Teaching science through inquiry method leads to unfolding of child’s mind, instead of stuffing it with

dead material. Curiosity is an innate urge of human beings whether young or old, educated or

illiterate; everyone has the desire to know the unknown. This urge of curiosity has been responsible

for all the discoveries and inventions.

Inquiry teaching has a supplementary character. It supplements the existing set of knowledge by

throwing open flood-gates of knowledge to be picked in both hands by the students.

Inquiry method supplies impetus to work with double zeal. The students feel themselves in

extraordinary high spirit with the topic. They take lessons just like play.

Inquiry method blesses the students with extra energy to face new challenges.

It is both rewarding and gratifying. It is only through this way of teaching that ever developing

subjects like science can be judiciously taught.

Inquiry technique ensures sublimation of natural endowments.

Besides being responsible for growth of civilization, spirit of inquiry infuses bits of good moral values.

Demerits:

In this method the teacher does not give readymade notes.

There is no single and ultimate method to arouse inquiry.

The objects or problems chosen for the purpose must be familiar with the students’ previous

knowledge.

15. a. Critically analyse meaning, merits and demerits of the following methods of teaching physical

science.

i. Demonstration Method

ii. Laboratory Method (2010) 10M

Ans:

Meaning of Demonstration method:

A demonstration is a technique designed to show or illustrate a procedure, process or

phenomenon. Demonstrations are concrete experiences that can be used for structuring future information

for students; when used discriminately, science demonstrations are effective and provide excellent at

induction for science with and lessons.

Merits of Demonstration Method:

It is appropriate for small classes.

The experiment is conducted by the teacher so there is no, or less breakage of apparatus.

It is less time consuming.

Students learn by seeing and observing.

The sight and hearing sense of the students’ is more active.

The students develop the power of observation, thinking and reasoning.

The students are able to understand the principles clearly and the knowledge acquired is permanent.

The teaching is effective if the numbers of apparatus are less.

There is possibility of using more sophisticated apparatus.

More difficult experiments can be undertaken.

More hazardous experiments may be attempted.

There is possibility to demonstrate manipulative and allied practical skills.

Page 31: Physical Science e-Question bank

30 | P a g e

There is possibility to draw the attention of all the pupils of the class simultaneously.

All students can see the same operation and techniques simultaneously.

Demerits of Demonstration Method:

The students do not get a chance to perform experiments.

Some students are not able to observe properly.

Sometimes the teacher is not able to perform the experiment properly and this creates a lot of

doubts about the subject in the minds of the students.

Only general knowledge about science can be demonstrated.

The concept of learning by doing has no place in this method.

It fails impart training in the scientific attitudes among the students.

Meaning of Laboratory Method:

Laboratory method usually involves carrying out experiments by either individuals or in small

groups. According to Dr. Mangal “Students are encouraged to derive the laws and principles of science

themselves by actually performing the experiments. The students are given all necessary materials and

equipment in the laboratory along with proper instructions for carrying out their experiments with their

own initiative and effort, then they carry on the experiments and record the observation and infer their

own results. They learn by their own experience, observation, testing and verification. The teacher

supervises their work and also guides them wherever needed.”

Merits of Laboratory Method:

The students to find out the qualitative or quantitative solutions to their problems.

Students learn by ‘Learning by Doing’ method; which is the best method.

It follows the child centred method.

It is based on important maxims of teaching/learning, such as known to unknown, simple to complex

and concrete to abstract etc.

It helps in developing scientific attitude, scientific outwork and scientific temper.

It makes students active and alert.

It provides training in scientific method.

Students become systematic in their day today affairs.

It paves the way for the exploration, experimentation and verification of scientific facts and

principles.

As it provides concrete and direct self-experience, the knowledge becomes clear and permanent.

Students learn the practical skills and proficiency in handling scientific apparatus and equipment.

It assists in providing good virtues like honesty, truthfulness and dignity of labour etc.

It helps in developing the habit of thinking, reasoning and problem solving.

It helps in inculcating the spirit of discovery.

Demerits of Laboratory Method:

It is expensive and uneconomical.

It takes more time to require at certain conclusions.

It requires strenuous efforts on the part of the teacher and students.

The speed of learning and teaching in this method is a demerit.

Page 32: Physical Science e-Question bank

31 | P a g e

It has limited applicability as every information cannot be verified through the laboratory work.

5. Explain the organizational steps in problem solving approach. (2011)

Ans:

The steps to be followed are as below:

Identifying and defining the problem:

Students come across several situations where they can apply skills and knowledge to a problem that

motivates them to participate in exploring. These problems can be stem from daily life or from the

background literature on some topic or from the place of the work of the student. Problems must be

chosen so that the student can partially but not completely understand them in terms of old ideas

and sufficient time must be allowed for the student to grapple with the situations, possibly with

appropriate hints to put the ideas together himself.

Formulating the hypothesis:

The student should focus on hypothesizing the relationship between two or more variables or

difference between two treatments. A review of literature would give students more content

information; various possible causes of the problem may be listed. Next the students are asked to

outline a laboratory procedure to test out their proposed solution.

Testing hypothesis by collecting and evaluating data:

Students are permitted to enter the laboratory to conduct their tests and note down observations.

The teacher’s job at this juncture is to ensure that the students work carefully and collect accurate

data.

Interpreting results:

All inferences bearing on the data at hand must be considered tentatively. This phase of problem-

solving demands an unusual amount of guidance from the teacher. Interpretation of data should be

based on proper use of techniques and charts, graphs, tables can be used to record the data.

Drawing conclusion:

The students are asked to determine if their results substantiate the expected solution. Conclusion

drawn on the basis of data should be accurately reported after proper interpretation. Findings should

be reported concisely and recommendations for further work should be mentioned. The students

should be able to make generalisations and apply it to their daily life.

15. a. Critically analyse the difference between Inductive approach and Deductive approach with

reference to following:

i. Meaning

ii. How and when to use

iii. Merits and Demerits (2011) 10M

Ans:

Aspects Inductive Method Deductive Method

Page 33: Physical Science e-Question bank

32 | P a g e

Meaning

It is a method of derivation of rule, or law or principle by considering several known examples.

It is a method where in rule or formula is stated first, then verified with on example, practiced several examples and to take application.

How and when to use

Steps in Inductive Approach: The following are the steps followed while using inductive approach to problem solving.

Sensing the problem ↓

Analysing the situation ↓

Organising the information ↓

Framing possible solutions ↓

Eliminating or Rejecting Irrelevant solutions

↓ Verification

↓ Generalisation

Steps in Deductive Approach: The steps to be followed while using deductive approach are as below:

Understanding the problem ↓

Collecting information ↓

Reviewing the relevant principle/rules/laws/formulae etc.

↓ Applying relevant rules to case in hand

↓ Drawing inferences

↓ Verifying the rule by applying to new

instances

Merits and Demerits

Merits of the Inductive Approach:

It helps understanding.

It is a scientific method.

It develops scientific attitude.

It is a logical method and develops critical thinking and habit of keen observation.

It is a method with psychological base and provides ample opportunities for student activities.

The method is based on the actual observations, thinking and experimentation.

It sustains students’ interest because they move from known to unknown.

It develops self-confidence.

It develops the habit of intelligent hard work.

Demerits:

It is limited in range and cannot be used in solving and understanding all topics in science.

The generalisation obtained from a few observations is not the complete study of the topic. To fix the topic in the mind of the learner a lot of supplementary work and practice is needed.

Inductive reasoning is not absolutely

Merits of the Deductive Approach:

It is a short and time saving method and hence is preferred by teachers. It is suitable for all classes.

It emphasises memory because students are required to memorise a large number of laws, formulae etc.

It is adequate and advantageous method for the revision of a topic.

It supplements inductive method and thus completes the inductive-deductive method of problem solving.

It enhances speed and efficiency in solving numerical problems.

Demerits:

It is not a scientific method because the approach of this method is confirmatory and not explanatory.

It encourages rote memory because pure deductive work requires some law, principle, formula for every type of problem and it demands blind memorization of a large number of such laws and formulae etc.

Page 34: Physical Science e-Question bank

33 | P a g e

conclusive. There are expectations to every rule and also certain limitations.

It is time consuming and laborious method.

This method can be used only when there are rules to be learnt.

In this method students are not completely active. It does not develop thinking, reasoning or discovery.
