Implications Of 3-D Printing For Teaching Geoscience Concepts To Students With Visual Impairments, Karen E. Koehler, Tiffany A. Wild, Sean Tikkun

Journal of Science Education for Students with Disabilities

This article presents the results of a study on the use of 3-D printed models in a science classroom for students with visual impairments and examines whether the use of these models impacts student conceptual understanding and misconceptions related to geosciences concepts, specifically plate tectonics.

Data were collected one week prior to instruction, one week after instruction and throughout the 3-week instructional period. Results showed that students with visual impairments held many of the same misconceptions about plate tectonics as students who are typically sighted. All students in this study had fewer misconceptions after the instructional period than they held …

Iterative Design Of A Simulation-Based Module For Teaching Evolution By Natural Selection, Jody Clarke-Midura, Denise S. Pope, Susan Maruca, Joel K. Abraham, Eli Meir

Instructional Technology and Learning Sciences Faculty Publications

Background: This research builds on a previous study that looked at the effectiveness of a simulation-based module for teaching students about the process of evolution by natural selection. While the previous study showed that the module was successful in teaching how natural selection works, the research uncovered some weaknesses in the design. In this paper, we used design-based research to investigate how design changes to the module affected not only students’ understanding of the concepts but also their usage of misconceptions in the assessments. We present results from two studies. In study 1, we looked at gains in understanding …
