This book describes a three-year research project which built on students’ learning experience, and addresses the issue of individual differences in mainstream primary schools in Hong Kong. The Learning Study model described in this volume presents a view of learning which stems from a humanistic interest, and stresses on the possible “experiences” that the student has gone through in their learning process. This project went through cycles of action research in implementing, evaluating and modifying a lesson. A total of 29 Learning Studies were conducted and the results showed remarkable improvement in students’ learning outcomes. Participant teachers also found the Learning Study model useful in their professional development.
