CORRELATION

Correlation is the technique of relating two subjects while teaching any one of them for facilitating meaningful learning and easy understanding of the topic under consideration. 

Principle 

Various school subjects must help the learner to understand his/her environment better.

Classification of correlation

1. Systematic correlation

Achieved through planning of the curriculum.

A panel of experts from different subjects work in group at the time of curriculum development. 

Related topics in various subjects are arranged scientifically in  same standard.

Its success depends on the cooperation and coordination of various subject teachers.

2. Incidental correlation

Achieved by planning of the teacher, 

Not a result of curriculum organisation.

Intrinsic in nature- teacher may correlate a topic with another of the same or previous standard.

Its success depends on wide knowledge and resourcefulness of the teacher.

Correlation of Science with other subjects

It can be treated under 3 heads

1. Correlation of science subjects with one another

Science cannot be taught in isolation. All branches of science ( physics, chemistry, zoology, botany, geology, agriculture etc) are correlated and independent upon each other. 

Eg : photosynthesis(botany) is related to physics & chemistry.

2. Correlation of science with other school subjects

a. Science and mathematics

Eg : Laws of reflection (physics), mathematical language is required to express the equation and to solve problems, mathematical computation is required.

b. Science and language

It is through  languages, the people in different parts of the world becomes aware of scientific developments / inventions .

c. Science and social science

The history of development of science, the developments in various field to reach the present stage - all these can be understood and this knowledge enables a student to become good and useful citizen, to lead an ideal civic life.

d. Science and drawing/craft

Leisure time and science club activities(chart preparation,card board modelling, clay modelling) are closely related to craft and drawing. 

3. Correlation of science with Social and physical environment

Teacher should relate the topics with daily life situations.

Eg :plastic (chemistry) can be correlated with hazards in surroundings due to plastic.

Advantages of correlation

1. Helps in integration of knowledge

2. Helps in effective, meaningful teaching and learning

3. Enhances motivation

4. Widens mental horizon

5. Enhances economy of effort

6. Helps in transfer of training
