A teacher is trying to teach the concept of good & bad conductors of electricity to class VI students. He begins by providing the definition of two terms. He then demonstrates how placing a good conductor like a safety pin between two ends of an open circuit consisting of a battery and a bulb completes it and bulb begins to glow. On the other hand, placing a poor conductor like a plastic scale does not complete the circuit and the bulb does not glow. He then invites the students turn-wise to his desk & asks them to themselves verify this. How would you evaluate the approach from an inquiry - oriented perspective?
