Seeing Chemistry through the Eyes of the Blind: A Case Study Examining Multiple Gas Law Representations

Journal of Chemical Education, v90 n6 p710-716 Jun 2013
Adequately accommodating students who are blind or low-vision (BLV) in the sciences has been a focus of recent inquiry, but much of the research to date has addressed broad accommodations rather than devising and testing specific teaching strategies that respond to the unique challenges of BLV students learning chemistry. This case study seeks to identify instructional techniques that support or impede the representation of information for BLV students in the context of a typical gas laws unit in a college chemistry course for science majors. Desimone's framework on selection and attention informed the analysis. A blind student participated in five interviews to provide insights on how symbols, equations, and concepts were communicated and interpreted. Findings identified in the analysis of transcripts pertain to three communication modalities of interest: verbal, written, and tactile representations of information to aid learning. Using the results generated for practitioners, the authors generated guidelines for faculty, teaching assistants, and university administrators to improve the teaching and learning chemistry for BLV students.
