Purpose: This study was performed to identify the relationship between stress perceived by middle school students and social support level and to investigate the factors affecting middle school students' smoking behavior. Method: The data was collected from four hundred and thirteen students of one boys' middle school and one girls' middle school. Data were analyzed by using SPSS 11.5 Win Program. Result: Smoking rate was higher in girls than boys. The factors affecting smoking behavior were drinking (OR=67.62, P<0.01), having one parent or no parents(OR=9.98, P<0.05), and higher material support(OR=4.67, P<0.05). Conclusion: This results showed that smoking prevention program is needed for girls' middle school students. To prevent smoking, teachers should help students to cope with stress from schools and their environments with careful guidance, and organized support for the student with one parent or no parents should also be established. Furthermore, guidance in student's relationships with peers is needed regarding appropriate allowance, drinking, or substance use.

The purpose of this study was to examine for middle school science textbooks published by the sixth curriculum to analyze STS material, activity, and space devoted to STS. Because most teachers and students are dependent upon textbooks in teaching and learning, analyzing science textbooks will give basic information to ascertain the extent to which the current school science incorporate STS themes. Results indicated that lots of STS topics in the middle school science text books are related to applications of science. They also revealed that about 3% of the narrative space is devoted to STS topics, with a range of 0.7% to 5.2%. The coverage of STS topics increases as grade level increases.

The purpose of this study was to investigate the effects of gender, science achievement, perceptions of science, and out-of-school experience on middle school students' science career aspiration. We conduced a survey on 181 middle school students and investigated whether there was a difference in perception of science and out-of-school experience according to science career aspiration, and derived the eight variables from survey items based on exploratory factor analysis. And we conducted a logistic regression analysis that explains the effects of eight derived variables, gender, and science achievement on science career aspiration. The result of analysis showed that only two factors such as 'interest and preference for science learning' and 'use of everyday tools' were significant to explain science career aspiration. It has thus been found that it is important to increase students' interest in and preferences for science learning and use of tools in everyday life in order to increase their science career aspiration.

The purpose of this study was to examine the effect of teaching science ethical issues relevant to the middle school science curriculum. The experimental subjects were 132 second grade middle school students in Seoul, who were divided into two groups without any statistical differences. The results of this study indicated that teaching ethical issues in science had a positive influence on students' attitudes toward science and fostered a positive impression of science education. Also, the students showed a positive attitude in dealing with ethical problems in science and technology. Regardless, the results of this study suggest that ethical education in science classes is effective in increasing positive attitude toward science and the ability of the students in addressing and resolving ethical problems in science and technology. As such, we strongly recommend that the science curriculum for middle school students be changed to integrate ethical issues in the science class.

The purpose of this study was to identify the preferable motivation types in science-learning and to find out the relationship between these types and scientific achievement of students in the secondary school. The subjects of the study were the second grade 581 students sampled by random cluster sampling method in three middle schools and three high schools. Three motivation types in science learning were analyzed, and they were named to task-orientation, ego-orientation and work-avoidance. From our results, secondary school students preferred task-orientation and work-avoidance to ego-orientation. In the case of task-orientation, high school students, especially in male group, had much preferable tendency than that of middle school students (p<0.001). It is interpreted that, as the level of scientific content of texts or the cognitive level of students were higher, a preference for the motivation type was focused to the task-orientation, especially in male group. In the case of ego-orientation, the female group showed much preferable tendency than that of male group in middle school (p<0.05). However, the female group in high school students was not different from the other groups in this motivation type. In the case of work-avoidance, there were not only a significant difference between males and females in the middle school (p<0.001), but also difference between middle and high school students in female group (p<0.05). It showed that female group had much preferable tendency than that of male group, and this tendency was decreased to the higher grade students in secondary school. From the analysis of correlation between motivation types and scientific achievement, task-orientation and work-avoidance were correlated to the scientific achievement. Its results were interpreted that the scientific achievement could be accomplished by the external motivation stimulus as well as the scientific content of texts. The task-orientation were comparatively correlated to the intelligence quality. It means that the students having high intelligence quality showed much preferable for the task-orientation.

This study aimed to identify structural relationships among variables by examining the direct and indirect effects of cognitive factors such as self-regulated learning strategy and definitional factors such as attitude toward science and scientific self-efficacy on science core competency in middle school students. To this end, the researcher examined the causal relationships among the variables using data from 438 students in all grades at S middle school in a metropolitan city. The results showed that middle school students' self-regulated learning strategy, attitude toward science, and scientific self-efficacy had a direct effect on science core competency, and that self-regulated learning strategy had a direct effect on attitude toward science and scientific self-efficacy. In addition, middle school students' self-regulated learning strategy had an indirect effect on science core competency through attitude toward science and scientific self-efficacy. Therefore, it is necessary to educate students from a comprehensive perspective that considers cognitive factors such as self-regulated learning strategy and defining factors such as attitude toward science and scientific self-efficacy in order to foster science core competency in middle school students.

This study presented the factor analysis on constructing the new factors affecting the middle school students' online learning behaviors from the questionnaires employed among middle school students. A total of 204 students participated and the data were collected in South Korea. The sample of middle school ninth-grade students was selected and used through purposive sampling. Findings from the factor analysis provided evidence for the eight-factor solution for the 35-items accounting for 66.15% of the shared variance. A wide range of factors has been considered to identify students' online learning behaviors. The appropriate experience and use of e-learning in the middle school period is also important as it will be a critical stepstone for future education. This research provides information that has been taken into account for advancing online learning to enhance the quality of e-learning systems for middle school students. The study results provided eight new factors affecting the middle school students' online learning behaviors; that is 1) communication using social media as a learning tool, 2) intention to share information using ICT, 3) addiction of technology, 4) adoption of technology, 5) seeking information using ICT, 6) use of social media learning, 7) information search using ICT, and 8) immersion of technology. This study confirmed that middle school students prefer communication using social media as a learning tool, and value intention to share information using ICT for the most part. The data obtained based on factor analysis can highlight the online learning behaviors towards a mixture of social media learning and ICT to ensure a new educational platform for the future of e-learning. This research expects to be useful for both middle schools of online learning to better understand students' online learning behaviors and design online learning environments and information professionals to better assist students who particularly need digital literacy.
