... course; however, outperformed others on a general scientific reasoning test given to multiple institutions science classes (Khan, 2001). The approach to teaching by this chemistry instructor could be characterized as model-based or the generate-evaluate-modify (GEM) approach, a first case of model-based instruction inside a classroom (Khan, 2007). 1 Figure 2 depicts the GEM approach to instruction. This approach to instruction involved the teacher promoting the generation of relationships internal to a model, evaluation of those relationships (often in light of new information), and modification of their models. ...
