Program Management System - 21st BCCE - Using Talking Probes to Conduct Chemistry Experiments Non-Visually

Workshop Title: Using Talking Probes to Conduct Chemistry Experiments Non-Visually
Descrption: The workshop will demonstrate how to use the Job Access for Windows with Speech (JAWS) text-to-speech screen reader interface with the Vernier Software & Technology Logger Pro data collection software package to collect data and give real-time probe readings in spoken output to students who are blind or otherwise print impaired. A series of JAWS hot keys have been created to provide spoken real-time probe readings and techniques to receive statistics information. Participants will also learn how to use an audio graph trace feature recently included in Logger Pro 3.8 designed to give print disabled persons a qualitative representation of the information being conveyed in a graph by means of an audible tone change. In addition to using the JAWS Logger Pro interface to enhance learning in the field of chemistry through the "Chemistry with Vernier" curriculum, hands-on ways to measure volume and lab bench organization will also be discussed.

Demo: In this workshop, we will be measuring the freezing point and melting point of water. The talking Vernier probes will be used to provide audible feedback to each user. In the second activity, each user will conduct endothermic and an exothermic reaction using hydrochloric acid and magnesium in one reaction, and the other will use citric acid and acidic acid. Temperature measurements will be made using the Vernier temperature probe. This will be interfaced with the JAWS text-to-speech screen reader to provide audible feedback to each participant.
