ComCoach Video Tutorial
The ComCoachVideo Tutorial is an online learning environment designed to help students improve their oral presentation skills. The website contains video clips illustrating effective and ineffective public speaking practices, as well as an interactive feedback component designed to foster students' ability to critically evaluate presentation segments.
The students featured in these clips are Cain Project presentation coaches and were instructed to enact both good and bad oral presentation behaviors.
In order to view the video clips, you will need to have the Macromedia Flash Player 8 installed on your computer.

Technically Speaking
This project is generously funded by a National Science Foundation Course, Curriculum and Laboratory Improvement grant (ID 0632804). The main goal of this project is to improve the oral communication skills of undergraduate mathematics and related STEM (Science, Technology, Engineering, and Mathematics) students. To achieve these goals, the project developed a series of video vignettes that portrayed student-actors presenting a small portion of a mathematical talk, roughly 30-90 seconds in length. In each set of vignettes, the student would give two ways to present an idea: one with shortcomings, the second correcting these shortcomings.
