What is VCAST?

Video Case Analysis of Student Thinking

Since 2017, we have been developing a series of online video-based instructional modules to engage secondary mathematics teacher candidates in analyzing cases of secondary students’ reasoning. Each online module features a mathematical task, a sequence of carefully-selected video clips of students articulating their ideas, and images of student work. This is a four-year project funded by the National Science Foundation (Award No. 1726543) that involves implementation at Boise State University as well as other institutions across the USA.
