Abstract

Students have prior knowledge about how the world works, including preconceptions and misconceptions. For more effective learning, instructional materials and activities need to be restructured/remodeled to address misconceptions and knowledge gaps as informed by assessment of prior knowledge. In particular, we have explored and examined materials with regard to topics of anguage and operational definitions, types of graphical representations, real world applications, and explicit discussion of micro-macro scale connections between a material's microstructure and its macroscopic properties. In engineering education, instruction must build on students' knowledge of scientific phenomena and direct it toward its use in engineering applications. In this research, teaching and learning materials and activities have been remodeled by use of feedback from assessment results on a regular basis in order to enhance students' conceptual change for more effective learning. Here, we report on the research question, "How can instructional materials be modified and adjusted to promote conceptual change by using formative and summative assessment in an introductory materials class?" A socio-constructivist pedagogy with learning by conceptual change frames the discussion and analysis of results of this research-to-practice teaching and learning paper. Information from a materials concept inventory (MCI), pre-post topic concept quizzes, team activities, classroom dialogue and homework were used to remodel class notes and activities. To promote conceptual change we use analogical reasoning and cognitive dissonance learning tools that are integrated in class notes and team activities. Incorporating hard data in "explain and predict activities" forces students to address anomalies in their mental models and revise and remodel their conceptual frameworks. We have found increasing gains in pre-post topic concept quizzes and the MCI with remodeled materials. The effect of the approaches applied here to promote more effective conceptual change are discussed in terms of remodeling of instructional materials, activities, and tools in the classroom. Some general approaches to improving student performance are suggested.
