다국어 초록 (Multilingual Abstract)

The purpose of this study was to examine the effects of metacognitive instructional strategies on students' understanding of circulation, respiration, and excretion concepts, students' metacognitive level, and self-efficacy. The subjects of the study were 75 middle school students, and metacognition strengthening strategy classes were applied to them. The contents of the science log written by students before, during, and after class were analyzed to determine the degree of understanding of circulation, respiration and excretion concepts. Additionally, the SPSS 27 statistical program was used to analyze the effects of this class application. The results of this study were as follows. First, through the use of metacognitive teaching strategies, it was possible to identify students' response characteristics according to their achievement level, and students' understanding of the concepts of circulation, respiration and excretion improved after class. Second, it was found that the achievement level of the 'middle and low' group improved more after class than the high group. Third, it was found that the metacognitive strengthening strategy class increased the students' metacognitive level and students' self-efficacy.
