Inquiry Training Model:
Though it is teacher determined, students are active participants in the whole process. Following are the steps involved in using this model:
Step I: The teacher presents a discrepant event, which motivates the students to find out the answer e.g., if a brush is put into from below and if you give strokes from above, instead of failing down, the brush climbs up with every stroke. Observing this event, the students are surprised and a question comes to their mind, “How can this happen?” or “Why does the brush behave in this manner?”
In order to find out the answers for this question then the teacher explains the procedure of inquiry (Step II). Now the students have to ask questions to the teacher, which can be answered only in the form of “Yes” or “No” e.g. the student can ask a question like “Is the inside wall of the cylinder rough?” which can be answered as “No”. But the question “How does the brush move?” will not be answered by the teacher.
The students ask question based on their hunches and assumptions and also modify their questions on the basis of information they get from the teacher while answering other’s questions.
This continues till the students find out the answer. Though the role of £ teacher is very important in this process, it is the students who are fully involved in finding out the solution.
This activity gives the students and experience in collecting information (through asking questions, listening to others, by experimenting) as well as generating and testing hypotheses.
Concept Attainment Model:
This is another model where the teacher helps the students to attain a particular concept, its characteristics and attributes. For example, the teacher tells the student that example 1 is a “Yes” example whereas example 4 is a “No” example. He/she tells them about two more examples. Then the students start collecting information about the concept they think the teacher must be having in mind. Then he/she tells the students to select any example and judge whether it is a “Yes” example or a “No” example.
