Tools Enabling A Student Who Is Blind In A Liberal Arts Chemistry Laboratory Course, Jessica Michael, H. David Wohlers
Journal of Science Education for Students with Disabilities
Chemistry laboratories ordinarily involve a number of visual observations and require qualitative and quantitative explanations of these observations. A student with blindness at Truman State University successfully completed the laboratory portion of the nonmajors liberal arts chemistry course with the assistance of a senior undergraduate chemistry education major, the guidance of a chemistry professor with blindness, and a variety of alternative laboratory methods. Volumes were measured using a notched syringe or the graduated cylinder pipet technique. Changes in color were measured by a Color Analysis Laboratory Sensor (CALS) and a Submersible Audio Light Sensor (SALS). Balance and Vernier probe measurements …

A new version of SALS (Submersible Audible Light Sensor) consists of a wireless light-detecting probe, Bluetooth ® connected to the iOS SALS App. As in previous versions of SALS, changes in detected light are converted to changes in sound, the latter now rendered with iPhone or iPad audio. The SALS probe assists the student with visual impairment in a variety of science activities, including those involving liquids. For example, when the SALS probe is placed in a reaction vessel, changes in light intensity caused by a chemical reaction or color indicator change are converted to changes in tone in real …
