Using Schema Training To Facilitate Students' Understanding Of Challenging Engineering Concepts In Heat Transfer And Thermodynamics, Dazhi Yang, Ruth Streveler, Ronald L. Miller, Inanc Senocak, Jim Slotta

Educational Technology Faculty Publications and Presentations

Background: Chi and colleagues have argued that some of the most challenging engineering concepts exhibit properties of emergent systems. However, students often lack a mental framework, or schema, for understanding emergence. Slotta and Chi posited that helping students develop a schema for emergent systems, referred to as schema training, would increase the understanding of challenging concepts exhibiting emergent properties.

Purpose: We tested the effectiveness of schema training and explored the nature of challenging concepts from thermodynamics and heat transfer. We investigated if schema training could (a) repair misconceptions in advanced engineering students and (b) prevent them in beginning engineering students. …

Development Of A Matlab Gui To Assist The Active Comprehension Of Biomedical Transport Phenomena Using A Visual Aid, Pranav Suri

Biomedical Engineering Undergraduate Honors Theses

Studies show that inductive teaching methods for Biomedical Transport Phenomena greatly benefit from an accompanying visual aid. The following project aimed to develop a MATLAB GUI application that illustrates steady-state heat transfer with a graph and heat map using user-defined boundary conditions and numerical parameters. The application was evaluated using a survey that first familiarized the user with the GUI by running through heat transfer exercises, then allowed the user to experiment with the application, and finally asked users about their experiences using a questionnaire. The responses indicate that the GUI was received positively overall, and that a MATLAB component …

Seventh-Grade Students' Use Of Heat Transfer Conceptions During An Engineering Design-Based Stem Integration Curriculum, Emilie A. Siverling, Tamara J. Moore

Integrated Engineering Department Publications

As the integration of STEM becomes increasingly important in pre-college education, it is important to study models of STEM integration. One model, engineering design-based STEM integration, has shown promising results in terms of student science content learning. This study’s purpose was to explore one student team’s use of heat transfer conceptions as they participated in an engineering design-based STEM integration curriculum. A case study research design, along with procedures from qualitative content analysis, were used to identify scientific and alternative conceptions that the seventh-grade students communicated during the unit. The main result is that the students spoke and wrote about …
