Methods of Instruction

Lecture cum Demonstration method

Ø  Combines the merits of lecture as well as demonstration method
Ø  Teacher performs or demonstrates the experiment in the class with active participation of the students
Ø  Students see the actual apparatus, equipments ,specimen etc
Ø  Since students observe the demonstration critically their powers of observation and reasoning are also improved


                 Merits

Ø  Multi sensory approach is followed in this method
Ø  It is economical when compared to individual lab work
Ø  The important maxims of teaching are followed in this method


                  Demerits
                                 
Ø  All pupils do not have the scope for lg by doing
Ø  The desirable practical skills are not developed

Heuristic Method

·        The word “Heuristic” is derived from the Greek word “Heurisco” which means
       “ to find out of”.
·        This method was  advocated by Prof.Henry Edward Armstrong , imperial college ,London in 1884
·        Students are placed as for as possible in the attitude of a discoverer


Principles of heuristic Method

ü  Principle of freedom
ü  Principle of experience
ü  Principle of learning by doing
ü  Principle of purpose fullness
ü  Principle of logical thinking
ü  Principle of individual work

Procedure

Ø  Laboratory work is essential for every pupils
Ø  A sheet of instructions concerning the problem is given to every pupil and he is effected to take observations or conduct experiments in accordance with instructions
Ø  He records  his observations
Ø  From the observations he has to draw his own conclusions.

Role of Teacher

v Teacher should be a treasure house of knowledge to give references
            to the pupils
v Teacher should possess curiosity and spirit of scientific investigation
v Teacher  should be a guide ,working partner and friend of pupils
v Teacher should provide an atmosphere of freedom in the classroom
v Teacher should device and plan problems according to the age, ability and interest of the pupils.


Merits

Ø  Students get first hand experience by performing experiment themselves.
Ø  Power of observation, reasoning and drawing inferences are developed
Ø  Pupil becomes self –Dependent ,Self –Reliant and self –confident
Ø  Facts learnt are retained for a much longer time
Ø  Individual differences can be chattered to
Ø  Relationship between teacher and taught becomes more intimate.

Demerits

Ø  Slow and tedious process and hence a prescribed course cannot be covered with in a specific period
Ø  It is impossible for every child to discover all laws of science
Ø  Gifted teachers are not available
Ø  As no text book is written on heuristic lines the teacher has to work hard to arrange problems for learners

Ø  It is not an economical method.
