This book project poses a major challenge to Japanese science education researchers in order to disseminate research findings on and to work towards maintaining the strength and nature of Japanese science education. It also presents a unique opportunity to initiate change and/or develop science education research in Japan. It provides some historical reasons essential to Japanese students’ success in international science tests such as TIMSS and PISA. Also, it helps to tap the potential of younger generation of science education researchers by introducing them to methods and designs in the research practice.
