The Video Mosaic Collaborative (VMC) is a relatively new project that is integrating a significant video collection of students and teachers in mathematics learning settings collected over 20+ years with sophisticated web-based collaboration tools. Ultimately, VMC seeks to enable pre-service and in-service educators to build their confidence and skill in working with mathematics students. The VMC anticipates that it can become a successful platform for researchers, teacher educators and practicing teachers to develop and share analyses, observations and results from mathematics interventions to improve the mathematics teaching and learning experience.
