Continual and explicit comparison to promote proactive facilitation during second computer language learning

This paper describes a Continual And Explicit Comparison (CAEC) approach to overcoming proactive inhibition and amplifying proactive facilitation in a second year Java course. The approach utilizes continual and explicit comparison to students' prior learning (in this case C++ programming knowledge) in early stages of learning the new language in order to more rapidly build understanding and more definitively form concept boundaries between the two languages. The majority of students felt the approach supported learning of the second language (proactive facilitation) without causing any interference with second language learning (i.e. minimal proactive inhibition). Some students also indicated that the approach enhanced their understanding of the first language (retroactive facilitation) and overwhelmingly agreed that the approach did not interfere with their understanding of the first language (i.e. minimal retroactive inhibition). Students also indicated that their Java programming ability and their enjoyment of programming increased during the period that the continual and explicit comparison approach was applied.
