Eliciting students’ conceptual understanding of electric circuits has been discussed as challenging to achieve owing to difficulties faced by students when learning circuit concepts. This difficulty has been attributed to the posit that students tend to hold very little formal preconceptions of electricity. This then becomes problematic as the level of complexity increases from the most basic to more advanced circuit concepts. This lack of formal prior knowledge has the potential to prevent students from being able to assimilate new material they come in contact with when instructed about electric circuit concepts. Other impeding factors reported have been the influence of students’ prior misconceptions, the abstract nature of the content, inadequate instructional strategies to provoke conceptual conflict and inadequate preparation of students from pre-requisite courses. However, a gap that still exists is the direct interaction between: (1) students’ prior knowledge, (2) the types of learning activities and (3) the design of the learning environment fueled by the decisions made by professors on how to teach circuit concepts. This study focused on exploring undergraduate electrical engineering students’ conceptual understanding of electric circuits based on the previously noted interaction. This study was conducted using three distinctive approaches: firstly, to investigate the influence of prior knowledge about other circuit phenomena when learning about more complex scientific concepts, secondly to examine the role of learning environments and student activities on students’ understanding of these concepts and thirdly to study the design and dissemination of knowledge about electric circuits in an introductory course. The overarching findings of this study deal primarily with the design of introductory courses having alignment between content, assessment and pedagogy. This alignment has direct impact on the decisions made about the teaching and application of content, design of the learning environment and how the content is communicated to the students. Findings have indicated the misalignment that exist between the three core areas of learning in course design. These results have theoretical and practical significance to the field of engineering as well as contribute to the body of literature on complex circuits such as alternating current (AC) circuits and students’ conceptual understanding. The core findings of the three studies independently and collectively have the ability to significantly impact the way future engineers are taught introductory concepts in their respective disciplines.
