New Perspectives in Science Education

The purpose of this study was to implement a junior high school science class that incorporates the instruction on formulation of consideration description under the peer evaluation activity, and to examine the effects of such instruction, focusing on the scientific expression of description of consideration. The peer evaluation activity is a learning activity in which learners use Goto's (2013) mutual evaluation sheet to exchange opinions with others about their considerations in observations and experiments, using the evaluation criteria to conduct self-assessment and peer evaluation, and then revise and improve their consideration based on the mutual evaluation sheet that shows their score evaluation and comment evaluation [1]. In previous studies on the peer evaluation activity, it has been found that they are effective in increasing the awareness of explaining one's own considerations and revising others' considerations [2], but it has been reported that there are challenges in writing about evidence, which is one of the components of argumentation [3]. Therefore, in this study, we thought that by using a learning method that incorporates the instruction on formulation of consideration description under the peer evaluation activity, we could aim at fostering scientific expression while realizing learners' collaborative learning. In this study, we analyzed the changes in the description of consideration that occurred as a result of this study, as well as the survey questions that were asked before and after the implementation of this study, and examined the effects of this study by focusing on scientific expressions. From the results of the analysis, it was suggested that learning to incorporate the instruction on formulation of consideration description under the peer evaluation activity had the effect of promoting the improvement of the description of consideration including "results (data)," "claim (conclusion)," and "evidence (reason)" that constitute scientific expression.
