The Opening the Gate (OTG) project aims to improve the success rate of students in developmental math class and give them subsequent opportunities to participate in STEM majors and careers. 

Part of the OTG program is to develop a lecture capture system for students in developmental math courses.

We took a research-based approach to developing our lecture capture system.

The OTG Technology Innovation Team studied the data from past developmental math tests to identify trouble spots and find opportunities for student performance.

The team also conducted focus groups and interviewed students, faculty, and technicians to optimize the delivery system.

The goal is to provide an accessible and useful lecture capture support system for every student in developmental math.

New videos added periodically!
