They are also often unaccustomed to instructional materials consisting of a combination of text, diagrams, and equations. This raises the question of whether instruction on elementary electrical circuit analysis for novice learners should employ contextualized representations of the circuits with familiar components, such as batteries, or employ abstract representations with the abstract engineering terms and symbols. A further question is if text labels in the circuit diagrams would aid these learners. This study examined these research questions with a “2 × 3” experimental design, in which the two forms of representation (abstract or contextualized) were considered under three types of diagram labeling (no labels, static labels, or interactive labels). The design was implemented in an instructional module on elementary circuit analysis for novice learners. Results indicated that abstract representations led to higher near- and far-transfer post-test scores, and that interactive (student-generated) labeling resulted in higher near-transfer scores than either the no-labels or static-labels conditions. These findings suggest that abstract representations promote the development of deep, transferrable knowledge and that generative methods of integration, such as interactive diagram labeling, can facilitate learning with multiple external representations.
