A. Using Images & Models.
An important teaching objective is describing the limitations of models and developing modeling skills in students (Harrison & Treagust, 1996). Models are an intrinsic part of education when teaching unobservable phenomena and it is important that students understand their use to avoid mistaking the model for reality. In addition, teachers need to be aware of the student’s prior knowledge to avoid the development of the misconception during the actual lesson. Students may reconcile their limited prior knowledge with the new material and develop a distorted new understanding of the concept.
