Perception of the experiment is one of the most important factors of students' understanding of scientific inquiry and the nature of science. This study examined the perception of middle and high school students of the meaning of 'experiment' in the biological sciences. Semantic network analysis (SNA) was especially used to visualize students' perception structure in this study. One hundred and ninety middle school students and 200 high school students participated in this study. Students responded to two questions on the meaning of 'experiment' in science and biology. This study constructed four semantic networks based on the collected response. As a result, middle school students about the 'experiment' in science are 'we', 'direct', 'principle' of such words was aware of the experiments from the center to the active side. The high school students' 'theory', 'true', 'information' were recognized as an experiment that explores the process of creating a knowledge center including the word. In addition, middle school students relative to 'experiment' of the creature around the 'dissection', 'body', high school students were recognized as 'life', 'observation' observation activities dealing with the living organisms and recognized as a core. The results of this study will be used as important evidence in the future to map out an experiment in biological science curriculum.

The purpose of this study was to investigate the effects of body weight, perception of body shape and satisfaction with body shape on obesity stress and self-esteem among middle school students. The participants in this study were 446 middle school students in K-city. The major results of this study are as follows. First, male students demonstrated higher obesity rates than female students, and female students considered themselves to be fatter and less satisfied with their body shape than male students. Female students had significantly more obesity-related stress than male students. Second, there were significant differences in physical obesity stress according to body weight status among male and female students, and there was statistically significant difference in psychological obesity stress according to body weight status among male students. Male and female students who considered themselves to be fatter and less satisfied with their body shape suffered from high obesity stress. Third, there was no significant difference in self-esteem according to body weight status, but self-esteem was affected by perception and satisfaction of body shape; male and female students who considered themselves to be fatter and less satisfied with their body shape showed low levels of self-esteem. As the result of regression analysis, psychological obesity stress was the strongest factor in explaining self-esteem among all students, and satisfaction of body shape was also found to be a significant variable among female students.

A survey of middle school students and teachers in Mokpo city has been done to understand the perception of environment of students and the present situation of environmental education in middle school. Only 2 of the 14 middle schools have chosen the environmental education course as a required subject. The majority of middle-school students in Mokpo city have learned the environmental education as a subordinate course included in the other subjects such as science, social science or technology. The environmental education in school has been done mostly through non-subject activities such as club activity, group work etc. The survey shows that almost all students think the environmental pollution is serious problem(83% of respondents) and they are especially interested in separate garbage collection(72%) and environmental conservation activity(63.9%) to protect the environment. The concerns about the environmental problems of students(57.7%) has increased after environmental education regardless educational methods or subjects. The students and teachers think that environmental education in school has not been carried out enough and almost all of them(68.4% of students, 97.5% of teachers) agree that the environmental education should be done as an independent subject. In order to more practical and effective environmental education, many opportunities to experience environmental conservation activities should be given during the environmental education course and the environmental education should be separated from other subjects to be taught independently. Moreover, it might be necessary to increase proportion of teachers in environmental disciplines and to develop various teaching methods.

This paper focused on examining the middle school students' perceptions of characteristics(personal knowledge, human responsibility, impact on personal life, and predicted trend, behavior will) of 10 global and 8 local environmental issues. Subjects(N=516) demonstrated by completing a survey that they perceived the characteristics of issues differently on global and local scales, and to a degree those characteristics are related. First, middle school students' perceptions of global and local environmental issues were above mid-point mainly, and perceptions of local environmental issues were higher than those of global environmental issues. At perceptions of characteristics, They perceived that the personal knowledge of global environmental issues were higher than those of local issues, that the human responsibility effects on global environmental issues more than local environmental issues, that global environmental issues in the future, will be more serious. For each environmental issues, the perception of global warming among the global issues was highest, the perception of yellow dust and air pollution among the local issues was highest. For perceptions of characteristics, behavior will to solve the environmental issues was lower than that of 4 characteristics(personal knowledge, human responsibility, impact on personal life, and predicted trend). Second, there was significant difference of the perceptions of two scale environmental issues for area and sex. It showed that Seoul students' perceptions were higher than Kong-ju students' perceptions according to area, and that girl students' perceptions were higher than boy students' perceptions according to sex. Third, correlations among issues were significant. Especially, it was positive relationship between knowledge and human responsibility, human responsibility and impact on personal human responsibility and predicted trend. Educators and communicators should take into account the perceived characteristics of environmental issues and choose effective information sources and teaching methods to improve students' understanding of human-induced environmental changes.

This study was conducted to analyse middle school students' perceptions of seafood as well as their eating experiences and favorite cooking methods for seafood. It also examined the frequency and use of seafood on school lunch menus. Questionnaires were distributed to 739 students in 5 middle schools in the Busan area. On a scale of 5.00, the average scores for perceptions toward seafood were as follows: 3.67 for health & nutrition, 3.53 for taste, 2.53 for smell, 2.77 for convenience. The male students had significantly_(p<0.05) higher perception scores for health & nutrition, taste, and smell than the female students. Among 38 types of seafoods, the highest percentages for eating experiences included seaweed_(99.2%), anchovies_(99.1%), fried fish paste_(98.6%), shrimp_(98.4%), crab_(98.2%), squid_(97.9%), sea mustard_(97.8%), mackerel_(97.7%), dried squid_(97.3%), and hair tail_(96.9%). However, the majority of students had eaten a limited amount of seafood. The degree of seafood intake at home was significantly_(p<0.01) higher than at school. The students' favorite cooking methods for seafood were in the order of grilling, stir-frying, steaming, deep-fat frying, and soup. However, the middle school lunch programs primarily served as soup, seasoning, stir-fried, braised, deep-fat fried, and grilled, respectively. The main reasons for leaving seafood on a plate were inconvenience due to the fishbones_(62.7%), tasteless_(45.4%), and disliking the smell_(35.7%). Improvements that students wanted for seafood on school lunch menus included removal of fishbone for convenience_(67.0%), taste_(52.0), and increased variety of seafood types_(38.2%).

This study aimed to investigate how middle school teachers perceived major features of the 'Free Learning Semester'. In 2013, the Free Learning Semester has been proposed by Korean government to provide students with the educational programs which deals with various activities in classroom in order to increase student's learning ability. The Free Learning Semester helps students to figure out their dreams and develops their talents. The government plans to expand the Free Learning Semester to all middle schools by 2016. Since teacher's perception is an important matter in the application of the Free Learning Semester, this study seeks to document the changes in curriculum by observing the perception of teachers in the school that implemented the Free Learning Semesters and those that did not implemented the Free Learning Semesters. 172 teachers from nine middle schools in Busan that their school schedules allowed were surveyed. Two school which operated the Free Learning Semester were compared to seven schools which did not operate the Free Learning Semester. The results are summarized as follows: First, almost all (97.7%) teachers in the Free Learning Semester schools have completed a training whereas 74.6% of the teachers in the non-Free Learning Semester schools have not. The usefulness of the training was satisfactory, but the teachers in the Free Learning Semester Schools wanted more practical help with the curriculum. Second, the result, which was statistically significant(p<.05), revealed that the first grade second semester of middle school was the best time to implement the Free Learning Semester. In order for its successful establishment in schools, there needs to be a reliable and effective evaluation system. However, the results regarding the introduction and management of the new system were not statistically significant. Lastly, in the Free Learning Semester Schools, the changes in teachers' perception were statistically significant (p<.05). The results show that the teachers need the training and the teacher's community to implement the curriculum and set a basis for valuation.

The purpose of this study was to investigate self-esteem, body image, body cathexis and body attitude of female middle school students. A total of 298 subjects were included in this study. Subjects were classified into weight control group and a non weight control group. As a result of analyzing body shapes satisfaction was higher in the non weight control group 2.83 than in the weight control group 2.28 (p<0.001). The weight control group revealed lower body satisfaction than the non weight control group. The result of the reason for weight control was the ratio of 'weight loss' 84.6%, respectively (p<0.001). Factors impacting physical image of female middle school students were analyzed as friends (3.46), internet (3.22), and TV (3.13). Results suggest that educational program should be combined with a positive emphasis on physical image and self-esteem for female middle school students. Also, there was a high correlation between body weight and self-esteem. Results indicate that female middle school students are interested in weight loss with the wrong body image. Therefore, female middle school students should be provided with an educational approach to such issues so that they have a realistic perception of their body and form realistic values about self-esteem and body.
