An Activity Aimed At Improving Student Explanations Of Biological Mechanisms, Caleb M. Trujillo, Trevor R. Anderson, Nancy J. Pelaez
An Activity Aimed At Improving Student Explanations Of Biological Mechanisms, Caleb M. Trujillo, Trevor R. Anderson, Nancy J. Pelaez
PIBERG Instructional Innovation Materials
This document is intended for use by instructors and their students. The activity contains steps to introduce students to the MACH model involving analyzing and discussing explanations about biological mechanisms. Initially, students read modified articles about biological mechanisms during class, although instructors may prefer to assign readings outside of class before the activity. During the activity, students are required to analyze the readings for evidence of research methods, analogies, context, and mechanisms. In so doing, students learn how to integrate the information pertaining to each of the MACH model components into a coherent explanation about their biological mechanism. After performing …
A Tetrahedral Version Of The Mach Model For Explaining Biological Mechanisms, Caleb M. Trujillo, Trevor R. Anderson, Nancy J. Pelaez
A Tetrahedral Version Of The Mach Model For Explaining Biological Mechanisms, Caleb M. Trujillo, Trevor R. Anderson, Nancy J. Pelaez
PIBERG Instructional Innovation Materials
This document is intended for both instructors and students. Modified from the original MACH model this version, once cut and folded, creates a tetrahedral model that can conveniently be used as a teaching and learning tool to inform and guide students on how to write expert quality explanations of biological mechanisms. Each vertex of the tetrahedron represents a component of the model namely, Methods, Analogy, Context, and How. For a coherent and complete explanation about molecular mechanisms, it is important to integrate information pertaining to all four components of the model. The tetrahedral MACH model has been tested in both …
Engaging Non-Scientists In Stem Through Problem-Based Learning And Service Learning, Andrew Tawfik, Rebecca J. Trueman, Matthew M. Lorz
Engaging Non-Scientists In Stem Through Problem-Based Learning And Service Learning, Andrew Tawfik, Rebecca J. Trueman, Matthew M. Lorz
Interdisciplinary Journal of Problem-Based Learning
This study follows the evolution of a single biology course designed for non-science majors. In its original design, the course used only traditional pedagogical techniques, such as lecture and textbook homework assignments. Over several iterations of the course, the class combined problem-based learning (PBL) and service learning to better support student knowledge. For this study, our goal was for students to learn biology concepts as they engaged in a lake cleanup project within the greater Chicago metropolitan area. Data sources consisted of pretest, posttest, and final exam scores to assess learning. The results suggest the combination of PBL and service …
