Flip video cameras can be used to record students explaining their thinking. Recording can identify “before and after” shifts in student thinking or can help a teacher to identify student learning needs or misconceptions.
Having students communicate their approach to solving a problem or their understanding of a concept helps to lay the ground for students to participate in mathematical discourse. Some students prefer to communicate their ideas orally rather than writing them down. Others may find talking to a camera less threatening than talking in front of their peers. Giving students time to prepare and practise their presentation, and supporting them with the mathematical language they need to communicate their ideas, can help them consolidate their understanding.
