The purpose of this study is to examine the concept of Greenhouse Effect as understood by middle school high school university students using a closed-form questionnaire. Based on results of the questionnaire which was administered to 619, the extent to which alternative concepts were held was quantified and compared the difference of various group based on grade level. gender, text and major. Also, subjects were divided into two groups, one is middle school students and the other is high school university students and common themes within conceptual framework of each group were identified by factor analysis. The result showed that students confused Greenhouse Effect with ozone layer depletion in stratosphere and linked familiar contamination around everyday life. acid rain. radioactive contamination, nuclear arsenal to Greenhouse Effect. These trends were more appreciable in female than male, biology major than any other major and text did not make any significant difference. In addition, the result of factor analysis showed that two groups linked familiar contamination around everyday life to Greenhouse Effect and high school university students understand the consequences of an increase in the Greenhouse Effect more systematically than middle school student, perceived the relation between the origin of an increase in the Greenhouse Effect and human activity but confused Greenhouse Effect with ozone layer depletion in stratosphere.

This study investigated the academic achievement of science and high school students according to the characteristics of R&E activities in mathematics and science. In addition, based on the survey results, the correlation between R&E activity characteristics and mathematics and science academic achievement was studied through correlation analysis and factor analysis between subjects. There was a difference in academic achievement in mathematics and science according to the characteristics of the R&E activity area, and the experience of R&E activity was found to be closely related to the academic achievement of related subjects. Depending on the area of R&E activity, mathematical and scientific academic achievement was found to be two factors: mathematical logic and natural understanding. Natural understanding factors significantly influenced students' academic achievement in mathematics, physics, and life sciences, and mathematical logic factors significantly influenced the academic achievement of students in chemistry and earth science subjects. In particular, mathematical logic ability was concentrated in excellent physics class students, and natural understanding ability was concentrated in excellent life science class students. Since the characteristics of the R & E activity area greatly influence the academic achievement of mathematics and science, it will significantly contribute to the selection and operation of the R & E activity area of science high school students.

Four science concepts were selected from high school science textbook to investigate the differences in priorities of students knowledge activated during solving earth science problems in laboratory and earth science environmental contexts. Two items, one for laboratory context and the other for earth environmental context, were developed for earth selected concept The subjects were constituted of 192 students in 11th grade and 196 in 12th grade in one senior high school. Students' responses were categorized using graph models and analyzed in terms of 'Common Activated Knowledge'(CAK). and 'Specific Activated Knowledge'(SAK) across students' cognitive frames, grades, and sex. As contextual differences of the problems increased, context effects in priorities of CAK were reported in favor of laboratory context, on the contrary those of SAK in favor of earth environmental context. Context effects were reported across cognitive frames, especially students with laboratory cognitive frames showed more significant context effects than others. Lower graders and girls showed relatively large context effects. The results of this study showed that science concepts learned in a laboratory context are not easily transferred to earth environmental context. Therefore, special instructional strategies should be developed to overcome the context effect s according to activated knowledges with high priorities in laboratory and earth environmental context.

The purpose of this study is to find out how well the middle school students are practicing the health promotion behaviors and the factors relating their health promotion behavior. Questionnaire survey on 922 middle school students attending 6 middle schools (three middle schools for each sex) located in Taegu City from the 7th through 19th of Feb. 2000 were conducted. The following were as follows; 1. The perceived health status is higher in male students than in female students(p〈0.01). And the ratio of the students' feeling that they are healthy becomes also high in proportion to their economic status, and their mothers' educational level, and their parents' interest in health(p〈0.01). The perceived importance of health is high in proportion to the students' economic status, and their parent's interest in health. 2. In case of the Health Locus of Control in Personality, the students with both parents have higher trend of inner control than the students with single mother or single father. The perceived self efficacy is significantly higher in male students than in female students(p〈0.01). And it becomes significantly high in-proportion to the students' economic status and their parents' educational level and interest in health(p〈0.01). It is also higher in the students who had no diseases. 3. In case of the perceived benefit of the health promotion behavior, the ratio of the students responding that it is high is higher in male students than in female students(p〈0.01). It also becomes high in proportion to the students' economic status, and their parent's educational level and interest in health(p〈0.01). The barriers of the health promotion behavior was found to have no variables that are related to itself. 4. According to the data from Multiple Regression of Analysis which has the health promotion behavior practice as a subordinate variable, in male students' case the degree of health promotion behavior practice becomes high in proportion to their parents' interest in health, and the perceived health status. Their degree of health promotion behavior practice is also in proportion to their perceived self efficacy and the perceived benefit of the health promotion behavior practice. But in case of the barriers of the health promotion behavior practice, the result is the opposite. As to the female students, their health behavior practice becomes high in proportion to their parents' interest in health. It also becomes high in proportion to the perceived health status, the understanding of the importance of the health, the perceived self efficacy and the perceived benefit of the health promotion behavior. But in case of the barriers of the health promotion behavior, it was the same as the male students' case.
