The POE approach is one of the teaching strategies in inquiry-based science teaching. POE stands for Predict, Observe and Explain.
This video will help teachers facilitate the POE approach in delivering a lesson on electricity and magnetism with the use of an improvised DC motor. First, the teacher makes the students predict first what will happen to the coil in the setup after they have been oriented on the direction of the force when the current runs perpendicular to the magnetic field. Then the students observe what really happened so they will be asked what they have observed to see if their predictions were correct. Afterwards the teacher tells his students to give an explanation on what they have observed and, if ever, why they did not get the right prediction. Bear in mind that even if the DC motor shown here does not have a commutator, the coil still moves in a continuous spinning movement because of the momentary disconnection that happens when the coil goes on the other side. This is due to the movement of the wire resting on the paperclips. Therefore, no force counteracting the motion will take place. This lesson is appropriate for Grade 10 students.
