| Abstract: | Much has been made about the difficulties students have in transferring their learning from one context to another. We suggest that students learning from examples use  imitation , a subtype of analogical problem solving (APS). Whereas APS involves manipulating a mental representation, imitation involves mapping the surface features of a source example to a target problem and no assumptions are made about what a student knows. Often imitating a close variant of a source problem is likely to be relatively successful; however, trying to solve a distant variant by imitating an example creates difficulties in mapping values and adapting the source example to the target. In this paper we argue that some students' inability to transfer their learning is very often due to the teaching material rather than any failure on the part of the student. To this end, we have developed an interpretation theory based on the proportional analogy framework (a:b::c:d) which can be applied to text analysis. The theory is demonstrated using examples taken mainly from computer programming textbooks. |
