Dr Leung Chi Keung Eddie and his colleagues have received the Certificate of Merit from the Quality Education Fund for their QEF team project “Promoting Problem-solving Practices among Teachers and Pupils in Primary Mathematics”. Problem solving is widely considered as an important aspect of mathematics. However, problem solving activities were not common in primary classroom before the implementation of this project, which was purposefully developed to meet this need. The project included intensive teacher professional development programme, development and implementation of classroom problem solving activities, and production of high-quality resources. The teachers of the ten participating primary schools reported that there was a gradual positive change in students’ attitude and their ability towards problem solving.
