An instructional method, based on POE (Predict-Observe-Explain), for teaching two basic wave properties and the wave nature of light

Abstract

Abstract This work presents a series of lessons containing didactic experiments, as well as the related educational research. The series concerns the instruction of prospective primary school teachers who possess a weak Physics background. The main topics of instruction are: basic concepts of wave behavior (mainly interference and diffraction), as well as the wave properties of light. This instruction is based on POE (Predict-Observe-Explain) techniques. It constitutes the basis of a broader effort in the making, which aims at teaching future teachers about wave properties and wave-particle duality. The benefits of teaching such notions of waves to teachers are examined, the learners’ previous knowledge and their views are scrutinised, and their learning progress is monitored. As a further step, the overall outcome of the improvement of learners’ knowledge regarding the given concepts is examined, using educational research tools.
