변인통제 문제해결 과정에서 나타난 초등학생의 실험설계 및 증거제시 특성 = Characteristics of Experimental Design and Evidence Choice of Elementary School Students in Problem Solving Process Related to Controlling Variable

다국어 초록 (Multilingual Abstract)

The purpose of this study was to analyze characteristics of experimental design and evidence choice of the elementary school students in problem solving process related to controlling variable. For this study, 96 6th grade students were selected and tested with Science Reasoning Task. This study revealed that the types of experimental design were categorized as variance of control variable, controlling of causal variable, perfect controlling variable, imperfect controlling variable, variance of all variable. Prior belief had a strong influence on student`s experimental design. The types of evidence choice were categorized as perfect controlling variable, controlling causal variable, variance of causal variable. The degree of controlling variable in evidence choice process was much lower than that in experimental design. Most students tended to choose evidence according to prior belief without controlling variable. The results of this study implied that student`s prior belief and characteristic of science process skills should be considered to develop program for promoting controlling variable ability.
