Designing a web-based cognitive tool to enhance mathematical problem solving
Designing web-based video cases for teacher learning and teacher development: The Singapore experience
Video cases have been shown as effective tools to support teacher learning and teacher development. This study aims to design web-based video cases to support teachers in mathematical problem solving. Two video cases were built by drawing on data from a three-year funded project in Singapore. The first case is built on two Grade 5 teachers’ different pedagogy in conducting problem solving activities while the second case draws on different challenges that two pairs of Grade 5 students experienced in the process of solving problems. The framing includes case commentary, guiding questions, and discussion forum to help users reflect on their practices and initiate peer-sharing and -learning among users. The long-term goal of the design is to build a virtual community of practice.
