CORRELATION

CONCEPT OF CORRELATION

• It means the relationship between different subjects of the curriculum.

• It can be Direct / Reciprocal.• Development of the mind can be achieved when

the person has got the ability to solve problems.• To solve that practical difficulty combined

knowledge of physics and other branches of knowledge is necessary.

• The interrelationship of science must be taught in schools in relation to another subjects.

• The child must know the importance between the different branches of knowledge.

CORRELATION IS OF THREE KINDS:

• Correlation within the subject• Correlation with other subjects• Correlation with life and environment

Correlation of science with other subjects can be of two types :

• Incidental Correlation• Systematic Correlation

INCIDENTAL CORRELATION

• Natural correlation.• It means a broad treatment of the subject that

brings about points of similarities between science and other related subjects.

• Success of incidental correlation depends on ‘wide knowledge and versatility of the science teacher’ .

EXAMPLES OF INCIDENTAL CORRELATION

A chemistry teacher while teaching about, teacher says about Haemoglobin, carrier of And mountaineers use carriers.A chemistry teacher while teaching about the

structure of atom correlates with history by telling about Kanada muni and the progress in ancient India.

A Biology teacher while teaching about eye correlates with a camera and the formation of image in a convex lens.

SYSTEMATIC CORRELATION

• It is achieved by a careful organization of curriculum in different subjects .

• It can be effective only when the teachers of different subjects co-operate and co-ordinate their work.

Distinction between Incidental & Systematic Correlation

INCIDENTAL CORRELATION SYSTEMATIC CORRELATION

1. It correlates the subject matter and makes use of casually while teaching a unit.

1. Systematic correlation in curriculum development is well planned and organized effort of a group of teachers.

2. It may go unnoticed by some students who are inattentive.

2. It is noticed by the teachers.

3. If Incidental Correlation is not made with stress the student may feel confused as to why the teacher is talking of a topic in the History in Physics / Chemistry class.

3. The relation is made clear to the student.

4. Transfer of learning achieved is not satisfactory.

4. Maximum transfer of learning is achieved.

INCIDENTAL CORRELATION SYSTEMATIC CORRELATION

5. It doesn’t prevent repetition and the student tends to feel bored.

5. It avoids repetition.

6. It is in the usual Classroom. 6. It prevents wastage of energy and time in the classroom.

7. Work of teachers remains individualized.

7. Co-operation between teachers is developed.

CORRELATION OF SCIENCE WITHIN THE SUBJECT

• All the branches of science are interdependent upon each other & a no: of facts and principles which are common to various science subjects.

• As a result , new subjects like Physical chemistry,Bio-Physics,Bio-Chemistry,Soil Chemistry , Electrochemisry , Geo- Physics have been introduced.

• Subject like ‘atom’, ‘heat of a chemical reaction’, ‘Electrolysis’, are of equal importance to a Physicist and Chemist.

• Physics provides instruments for the study of almost all other science subjects , thus correlating many principles of physics with other science subjects.

• Chemistry find its applications in various subjects like physics(theory of electrochemical reaction),biology(chemical manuring , air and water);hygiene and physiology(air , water , chemistry of foods , chemistry of blood and purification of water)

PHYSICS LIGHT: light and health, light and germs , light and

vitamins , artificial sunlight , in sun-bathing. Eye as camera , use of spectacles. Natural and artificial lighting, physics and physiology of room.

HEAT: temperature of body, heat as energy, heating of rooms, humidity, ventilation , sweat, evaporation, treatment of heat burns.

SOUND: ear how it works , effect of noise on health.

PHYSICS

ELECTRICITY : use of electricity in homes, heating and lighting for health , electricity as a curative agent, X-ray, electric shock and its treatment.

MECHANICS : bones and muscles from mechanical systems, work and energy of human body.

CHEMISTRY

• The chemistry of foods, digestive system, vitamins , chemistry of blood, soap , hard and soft water detergents.

BIOLOGY

• Development , structure and chief functions of the body breathing and correlation of blood.
