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 …
The Mechanism Of Dishabituation, Genevieve Steiner, Robert Barry
The Mechanism Of Dishabituation, Genevieve Steiner, Robert Barry
Faculty of Social Sciences - Papers (Archive)
The dual-process theory of habituation attributes dishabituation, an increase in responding to a habituated stimulus after an interpolated deviant, to sensitization, a change in arousal. Our previous investigations into elicitation and habituation of the electrodermal orienting reflex (OR) showed that dishabituation is independent of sensitization for indifferent stimuli, arguing against dual-process theory's explanation. However, this could not be tested for significant stimuli in that study, because sensitization was confounded with incomplete resolution of the preceding OR. This study aimed to clarify the mechanism of dishabituation for significant stimuli by extending the stimulus onset asynchrony (SOA) beyond the time required for …
