1. Heuristic Method Submitted by :: Athira Krishnan A r Natural science

2. Introduction The heuristic method is a problem solving approach that uses practical experience based technique to find solutions. It typically provide acceptable solutions more rapidly than traditional optimization techniques Students get training in scientific method of approaching and solving problems, it provides training in method knowledge is secondary. The name of this method is derived from the Greek word “HURISKIN” meaning “l FIND”

3. Profunder HENRY EDWARD ARMSTRONG “Heuristic method is a method of teaching which involves our placing the students as far as possible in the attitude of a discoverer”.

4. Essential conditions of heuristic learning Different problems are assigned to the class and each student is made to find out the solution. Each child acquires information from different sources, they are free to move and discuss problems with their class mates. Small level of guidance from the teacher is provided, questions based on child’s observations are asked. Therefore, the child learns how to attack a problem, gather data, interpret the data, formulate solutions and arrive at conclusions.

5. Objectives of heuristic method To develop among students the ability of self-learning.
To develop among students the ability of critical thinking.
To develop among students the attitude of logical thinking.
To develop among students the attitude of accepting truth only after verification.
To develop among students the attitude of not accepting things based on blind faith. To develop among students the scientific thinking.

6. Principles The principle of Activity Principle of logical thinking Principle of proceeding from known to unknown Principle of purposeful experience Principle of self thinking and self study

7. Role of a teacher Should be a man of knowledge.
→ He should arose interest and curiosity of students.
→should provide an atmosphere of freedom in the class and should plan problems according to age, interest and ability of students.
→ The teacher plays a significant role in developing scientific attitude and values at the same time allows the freedom of work.
→The teacher should be studious who can give relevant references as and when required by the students The teacher should prepare a detailed instruction sheet for the students.

8. → The teacher may organize field trips, Visit to museums and Exhibitions to supplement the knowledge of the students
→ The teacher plays an important role in draw conclusions from the observations and experimentations.
→ The teacher should be sympathetic and courteous towards the students .The teacher should inculcate the skills of self-expression, self-development, self-confidence and self-help in the students.

9. Advantages Develops scientific and critical attitude among students
Pupils become self dependent, self reliant and self Confident
Hard work and learning by doing is encouraged.
More retention of knowledge and training in scientific method is encouraged.
Teacher – pupil relationship is strengthened.
Inculcates the scientific temperament by developing Scientific attitudes and scientific methodology. The students develop the habit of enquiry and investigation.

10. Disadvantages It is a long and time consuming process. Expensive method since it requires well equipped laboratory
Evaluation of Learning is tedious
No expert teachers to implement this method.
The method demands hard work, great efficiency, in scientific method etc from the teacher.
The method could be applied only to small classes with less number of students.
The method is time consuming that the syllabus will not be completed in the prescribed time period.
Sufficient skills and training are required for the gradation of the problems

11. Conclusion This method is not applicable in primary classes but can be practicable in middle and high classes. The success depends upon a teacher who is resourceful, alert, intelligent and expert in the method. In this method there should be no spoon-feeding on the part of the teacher. The pupil should be made to think and work independently.
