The purpose of this study was to explore middle school students' perceptions about earth systems in order to implement the 2009 revised national science curriculum effectively. A total of 1219 students participated in the survey and asked to determine their basic understandings about earth systems, self-reported knowledge level, and perceived significance level of the 23 earth systems concepts (contents). In relation to students' basic understandings about earth system, approximately 67% students reported that they didn't know about the term of the earth system. Atmosphere and hydrosphere were highly perceived as major component of earth system. However, cryoshere was perceived to be least familiar by the subjects. The findings also showed that students' self-reported knowledge level and significance level about major ESU#4, #5, #6 related concepts (contents) were significantly different by gender. Most of male students were more knowledgeable and perceived more significant than female students. Regarding the difference of the perceived significance level by grade, 10 out of 23 concepts were significantly different. Some implications for implementing the revised curriculum and school fields were discussed.

This survey is to compare the handwashing recognition and practice of middle school students in Korea and Nepal, according to the report that handwashing practice rate of Korea was significantly lower than those of developed countries. The handwashing survey tools of Korean CDC were used. As a result of analyzing data using SPSS/Win 23.0, there were differences in residential state, disease experience, and parental education level of subjects, handwashing practice was significantly higher in Nepal while higher handwashing recognition of Korea(p<.001). Among contents of handwashing practice, there were significant differences in drying methods, number of it with soap, time required, number of receiving education for it, and education methods. It is necessary to take measures to increase handwashing practice rate of Korea, while Nepal's is increasing by supplementing equipment and education even their handwashing recognition was low. This results are from a few middle school students in both countries by convenience sampling, therefore it is needed repeated studies with wider range of subjects.

In this study, epistemological views of middle school students on scientific inquiry were investigated. The Views of Scientific Inquiry Questionnaire was administered to 141 9th graders. The questionnaire consists of five open-ended items concerning the contexts of scientific investigation, the methods of scientific investigation, the interpretation of data, and the data and evidence. Analyses of the results indicated that their epistemological understanding of scientific inquiry were not adequate on the whole. Although the students suggested a variety of factors influencing scientists' decisions on the questions and the methods of investigation, many of the factors were minor. Only a few students specifically described the activities of scientists and the constituents of "scientific" activity, and students did not demonstrate adequate understanding of experimentation in science and multiple scientific methods. Moreover, the percentage of students who possessed the informed view that data can be variously interpreted was found to be low. The students also did not understand the distinctions between data and evidence. Educational implications are discussed.

The purpose of this study was to analyze the perception of academic difficulties of middle school students and their influences variables in technology subject. The subjects of this study were middle school students in the whole country. A total of 420 students were selected considering the grade and area for the survey. The data were collected by mail and analyzed using SPSS 22.0K. The results of this study were as follows : First, The academic difficulties perceived by middle school students in the technology subject were recognized as normal. Second, Middle school students perceived it as a lack of experience (opportunity) in the technology domain as a cause of academic difficulties. Third, In the learning process, the female students were more difficult to understand the related terms and theories than the male students. In the problem solving activities, the female students were more difficult than the male students in identifying problems, designing solutions, selecting solutions, modeling, testing solutions, and correcting improvements. Fourth, the academic difficulty in learning technology lesson was difficult in terms of terminology, theory, and practice activities in the order of Second, Third, and 1st grade. Fifth, lack of understanding knowledge, confusion of contents knowledge, lack of technical interest, shortage of class hours, lack of understanding of evaluation criteria were all influenced by the difficulty of technical subject learning. Sixth, the academic difficulty influencing the problem solving process was explained by understanding comprehension, content knowledge confusion, technical interest, class time, understanding of evaluation criteria.

This study aimed to identify middle school students' perceptions and practices of handwriting, and factors affecting their attitudes towards handwriting. Data were collected by means of a survey targeting 346 students enrolled in 9 middle schools(Male=172, Female=172, Unknown=2, M=13.5 years old, SD= .94). Interviews, too, were conducted with 12 students in order to identify the students' perceptions of handwriting. The analyses of both survey and interview data revealed the following: (1) the majority of the interviewee students believed that handwriting is useful for memory and summarization so as to get a better school grade, including performance evaluations; (2) Many of the interviewee students were unsatisfied with their handwriting skills, giving higher scores to their peers' handwriting; (3) 45.7% of the students reported that mother was the one who taught them how to write for the first time; and 49.7% of them had no learning experience of taking notes; (4) Girls than boys and 1st graders than 2 or 3 graders showed more positive attitude towards handwriting; and (5) A multiple regression analysis showed that all the variables entered in the regression model, including sex, grade, affective attitude toward hands-on activities, physical abilities, time spent using a computer, and perceptions of Korean characters, had significant impacts on the students' attitudes towards handwriting.

본 연구의 목적은 초 ${\cdot}$ 중학생들의 수학적 신념을 알아보고, 그러한 신념을 형성하는 요인들을 수학 교실의 상호작용에서 찾아보는 것이었다. 이를 위해, 초등학교 5, 6학년과 중학교 1, 2, 3학년 학생들의 수학적 신념을 질문지로 조사하였으며 각급 학교의 수학 교실에서 벌어지는 교수-학습 과정을 비디오로 촬영하여 각 교실의 사회적 규범들을 비교 분석하였다. 그 결과로서, 학생들은 수학은 이미 만들어진 규칙과 용어들로 이루어졌고 그 규칙에 따라 주어진 문제를 풀어 답을 구하는 것이 수학적 활동이라고 인식하고 있었다. 한편, 이러한 신념은 각급 교실에 형성된 사회수학적 규범과 일치했으며, 특히 개념설명과 새로운 전략 및 오류에 대한 반응과 관련된 사회수학적 규범이 학생들의 수학적 활동을 제한함으로써 그들의 신념을 결정하고 있었다.

The purpose of this study was to investigate relations between middle school science teachers' perception of students' learning styles and their teaching style. Data were collected by in-depth individual interviews with 20 experienced science teachers (14 years of teaching experience in average). Results indicated four categories of the relations: i.e. teachers implemented their teaching style (1) matching students' learning styles, (2) supplementing students' insufficient learning styles, (3) teacher-centered, but matching the diverse students' learning styles, and (4) based on their values and convictions. In general, teaching styles of the teachers did not match with their perceptions of students' learning styles. Instead, their teaching styles seemed to be more affected by their personal values and convictions.

Students' perception of science-related career strongly influences the formation of career motivation in science. Especially, the high level of science gifted students' positive perceptions plays an important role in allowing them to continue to study science. This study compared perceptions of science-related career between general and gifted middle school students using semantic network analysis. To ensure this end, we first structuralize semantic networks of science-related careers that students perceived. Then, we identified the characters of networks that two different student groups showed based on the structure matrix indices of semantic network analysis. The findings illustrated that the number of science-related careers shown in science gifted students' answer is more than in general students' answer. In addition, the science gifted students perceived more diverse science-related careers than general students. Second, scientific career such as natural scientists and professors were shown in the core of science gifted students' perception network whereas non-research oriented careers such as science teachers and doctors were shown in the core of general students' perception network. In this study, we identified the science gifted students' perceptions of science-related career was significantly different from the general students'. The findings of current study can be used for the science teachers to advise science gifted students on science-related careers.
