The purpose of this study was to investigate the effect of a metastrategic activity on the development of student variable controlling abilities. Three groups of seventh graders at a middle-school in the City of Daegu participated in this study: a metastrategy activity group (ME), a problem-solving activity group (PR), and a control group (CO). The ME group was given metastrategy activity worksheets, which required students to monitor, control, and evaluate variable control strategies in a specified situation. The PR group was given problem-solving activity worksheets, which were needed to solve problems in various situations. The results were seen as follows. First, the metastrategy activity group showed better achievement (p<.05) and a longer standing effect (p<.01) than the other groups in the development of variable control ability. The problem-solving activity group was more effective than the control group (p<.05) in the development of variable controlled ability, but there was no lasting effect of the acquired ability. Second, the metastrategic activity group was more effective than the problem-solving activity group in finding fixed variables (p<.01), but not as effective in uncovering independent variables. What is not transferred to the development of the ability to find dependent variables.

The purpose of this study is to compare junior high school students' conceptual changes about force and motion and their interest in science between a group with the instruction including sports experiential learning activities and a group with traditional instruction. In addition, for a group with sports experiential learning activities, students' conceptual changes and interest were examined according to the degree of their sports-experience before the instruction.The subject was 7th-grade students(N=82), and they were divided into two groups: experimental group and control group. The conceptual changes were positive in both groups. In the multiple choice questions the experimental group students(20.0%) were more positively changed than the control group students(17.2%). The number of students who responded with the right explanation increased 26.7% in the experimental group and 10.4% in the control group. The interest of the control group was significantly increased in the topic dimension(p<0.05). The interest of the experimental group was significantly increased in the experiential activity and the communicative activity(p<0.05). Students who had much sports-experience showed the most positive changes. Moreover the interest of these students was especially increased in internal motive, receptive activity, experiential activity, and communicative activity.

성인 조직범죄집단은 조직유지와 활발한 조직활동을 위해 청소년 비행집단의 구성원을 포섭하려한다. 그리고 청소년 비행집단의 구성원은 다양한 이유로 인하여 조직범죄집단에 유입된다. 이는 당해 비행청소년은 물론 그 주변의 청소년들에게도 악영향을 미친다. 이러한 양 집단 간의 연계를 통한 유입현상을 통제하기 위하여 우선 청소년을 대상으로 비행행위에 대한 예방목적의 프로그램 활용은 물론 보다 효과적인 제도의 운용을 위한 구체적 논의가 필요하다. 이에 대해 청소년들이 활동하고 서로를 접하는 공간인 학교와 지역사회에서의 통제는 필수적이며 이러한 이유로 경찰과의 협력을 통한 예방활동에 주목할 필요가 있다.

The purpose of this study was to analyze variable-controlling strategy (below vcs) and the ability to infer the effect of variables in Middle school students who experienced 'Thinking Science' activities in a CASE program. For this study, 71 9th grade students experienced in CASE program for 2 years were selected as the experimental group and 72 students were selected as the control group. All students were tested with Science Reasoning TaskVII. The five types of variable-controlling strategy were extracted from students' response. According to the result of this study, the students experienced in CASE program was more successful in the variable-controlling strategy of length, quality, and shape than the control group. The types of reasoning ability of the variable effect intuitively were categorized as possibility of reasoning, impossibility of reasoning, and impossibility of reversible thinking. It has shown that the reasoning ability of the experimental group was higher than that of the control group in the length and thickness variable effect. The results of this study implied that the variable controlling activities in CASE program could be effective for learning variable controlling, and eventually, for the development of reasoning ability of the variable controlling effect. In the ability to infer the effects of variables to get difficult Intuitively, both groups were similar to the rate of cognitive level reached to the formal operation in generalization, and the student of experimental group was 1.5 times faster than the control group.
