Learning improvement based on student 'self-assessment' : focusing on the case of an elementary school science class applying OPPA

The purpose of this study is to clarify the necessary elements and the effect of “self-assessment” for class improvement. The type of “self-assessment” used in this study promotes the awareness of the transformation of concepts the students and teachers employ in their thinking. In this study we examine the case of a 6th-grade elementary school science class that applies the OPPA-One Page Portfolio Assessment in learning about the “principle of burning” and the “lever rule”. The study clarified the three points below. First, it is important to pay special attention to the educator’s “self-assessment”. Next, as the educator’s “self-assessment” is based on the learners’ “self-assessment”, specific ideas for class improvement become apparent from this point of view. Finally, initiating a process of improvement becomes easier by applying OPPA to the class.
