Lesson Study is a credible teacher development approach which has its origins from Japan and is currently being implemented globally. Due to the unique educational needs of each country, including South Africa, there are numerous variations of Lesson Study. Through Lesson Study, a team of teachers work collaboratively to identify a problematic topic/concept, plan the lesson, observe the lesson while one teacher teaches, and then engage in reflective exercise to improve the lesson. The Teacher Development Through Lesson Study: Theory and Practice short course is aimed at improving classroom practice by enhancing teachers’ content knowledge and pedagogical skills. Although Lesson Study has been predominantly used to develop mathematics and science teachers in primary and junior secondary schools, it can be used to develop teachers (pre- and in-service) across the subjects.
