Repairing Misconceptions: A Case Study with Advanced Engineering Students on Their Use of Schema Training Modules Key words: misconceptions, difficult concepts, schema training

Abstract

The case study described in this paper was a formative evaluation on the adapted schema training modules and materials. The study was intended to gather feedback and suggestions from the intended audience in order to revise the training modules. The study also assessed students’ overall experiences and performance regarding the tryout of the modules. Both qualitative and quantitative data were collected from the participants. Based on the case of four participants, (1) the training materials were well adapted for undergraduate engineering students; (2) the training models were effective, (3) the training modules would be more effective for students with less coursework in the engineering subjects covered by the modules.

Introduction and Background

Misconceptions

Previous studies reported that misconceptions related to heat transfer, fluid mechanics, thermodynamics, and other engineering and science concepts persist among engineering students even after they completed college-level courses in the subjects.1- 2- 3 These misconceptions are not simple confusion or misunderstanding due to inaccurate or incomplete pieces of knowledge of the concepts.4-5 Such misconceptions are fundamental misconceptions about differences in the way that some molecular-scale engineering processes such as the diffusion differ from other observable and macro level processes such as the blood circulation.6

Such misconceptions are also robust and resistant to traditional instruction because the correct understanding of some challenging concepts not only requires students' knowledge of the differences in the way they behave from commonsense conceptions but also “overcome their (perhaps even innate) predisposition to conceive” them differently.6 To repair these misconceptions, Chi and her colleagues proposed an innovative instructional approach, ontological schema training methods, which focus on helping students develop appropriate schemas or conceptual frameworks for learning difficult engineering concepts.7- 8- 6-9

Ontological schema training method

The ontological schema training methods were based on assumptions about how students learn. One of the assumptions about how students learn new concepts is that students assimilate or encode new information into an existing schema or category.10 Assimilating new information into an existing schema help students make inferences about and assign attributes to a new concept or phenomenon.11 However, when students learn some particularly new challenging engineering concepts or processes, which are fundamentally different from their commonsense observable conceptions, they can make the wrong inference or assign incorrect attributes to the new concepts based on their existing commonsense schema. A simple everyday example is that
