중학생들의 자기장과 전자석에 관한 학습 성취도 향상을 위한 발생학습 모형의 적용 효과 = The Effect of Instruction using Generative Learning Model for Middle School Student's Conceptual about the Magnetic Field and Electromagnet

다국어 초록 (Multilingual Abstract)

In this study, the middle-school students' conceptions about the magnetic field and electromagnet were investigated, and the effect of instruction using generative learning model for middle school students' conceptual change about the magnetic field and electromagnet were analyzed. The subjects for the study were 8th grade 66 females and 71 males who were sampled from two middle schools in Busan, Korea. They were divided into two groups, one was experimental group and e other was control group. Traditional teaching and teaching using generative learning model were applied to the control group and experimental group, respectively. The pre-test and post-test tools, which are explanation after choice type test, were developed by the authors. The conclusion of the research are as follows : 1. According to the analysis of pre-test result, the students' correct answer rates about the magnetic field and electromagnet was found to be low as 55% in objective test on1y(mu1tip1e choice test), and 28% in explanation after choice test. The predominant misconceptions about街e magnetic field and electromagnet are as follows. Many students think that ; Magnetic field does not exist over the magnet, Plastic and oil block the magnetic field (or magnetic force), Magnet attracts all electrical conductors (or metals), In electromagnet, electrical current flows from coil to the core, Any material which is electrical conductor can be used as a core of electromagnet. 2. According to the analysis of objective post-test, students' achievement of the experimental group was 74%, while control group was 59%. According to the analysis of subjective post-test, they were 54% in experimental group, 31% in control group. Analyzing of t-test result, the instruction using generative learning model is more effective than traditional teaching(P ＜.01).
