This is the case of three institutions attempting to identify and address a need for professional development training for high school algebra teachers. Teachers across the state were facing two problems: (1) a need for training on how to successfully integrate the graphing calculator into the math curriculum and (2) training was not available that would fit into a teacher’s schedule. Teachers rarely had time to attend the instruction necessary to integrate new technology into the curricula being offered at remote sites. With Web-based training, teachers should be able to complete the training at their own pace and convenience. Online Calculator Training in Mathematics and Technology would demonstrate the effective use of online training to teach the basics of graphing calculators and the integration of graphing calculators into the math curriculum.
