The purpose of this study is to qualitatively examine the effects of graphics representation of trigonometry modelling concerning question generating and idea sharing. The experimental setting(Experiment Group) was one class (N=26) at a public high school. The modelling process was designed as a process-oriented conceptualization divided into three steps i.e., (1) game with idea sharing and question generating, (2) graphic representation, and (3) symbolization in the mathematical applied tasks related to trigonometry function. The result indicates that Graphic Representation with Game Activity increases the opportunity of question generating and idea sharing during experimental work. Also, the results show that the introduction of computer graphics enhances the teaching of mathematical quantity in highschool classrooms.

The point of departure is the Popularity of the electronic games among the youth generation. This study attempts to make up a questionnaire containing the questions which are intended for the youth generation realistically and at the same time in a meaningful way pedagogically. Any researcher who wants to understand the youth culture at the present time is necessary to approach the youth generation in a positive attitude of learning, so asking the questions to the youth generation is as important as having the answers. That is to say, this paper is not a statistical analysis of the questionnaire, nor a empirical research of youth's reception of the electronic games. Now that the emphasis of the paper is located on the very way of approaching the youth generation concerning the electronic games, this study starts with the university students in the first place because they are in a more advantageous milieu for conversation in the classroom on the subject. To be sure, this study will be able to cover the whole area of primary, junior or senior high-school by way of some modifications. Conclusively, this paper aims at providing with practical ideas of teaching, which immediately can be appropriated into the classroom by the teachers in the actual field, and drawing attention to the potential educational contents of the cultural products. Furthermore, the questionnaire proposed in the paper is meant for the first step towards the aesthetics of the electronic games with a view to the game-imagination.

This study identified essential areas of student satisfaction by presenting questions concerning each educational area. The measurement tool of this study was developed based on a literature review, and its validity and reliability were verified through qualitative research and exploratory and confirmatory factor analysis. To measure student satisfaction in university, we developed a tool comprising seven areas: curriculum and instruction; student advising, educational environment, student support, campus life, university image, and administrative services. A total of 54 questions were prepared, and 7 factors were derived. Cronbach's alpha was 0.970 for all questions and ranged from 0.70 to 0.93 for each factor. The results of the confirmatory factor analysis were GFI 0.830, CFI 0.916, TLI 0.910, RMR 0.047, and RMSEA 0.047, which confirmed the suitability of the research model. Moreover, the convergent validity showed that the questions in this tool consistently described the component areas. Therefore, the research tools developed in this study were found to be suitable for measuring student satisfaction.

The purpose of this study was to investigate students' and mentors' perceptions of Research and Education (R&E) programs in science high schools and science academies. The sample included 1,466 science high school/science academy students and 310 mentors. They filled out the survey, which consisted of the perceptions of R&E performance procedures (Selecting a topic, Learning topic-related knowledge, Designing and performing the research study, and Evaluating and presenting results), and R&E environment (Research period, meeting opportunities with mentor/subject, learning/experimental environment). The results showed that differences existed in the perceptions of R&E performance procedures and R&E environment, especially on selecting topics and learning topic-related knowledge stages. At the end of the paper, suggestions were included for improving R&E.

The purpose of the research is to offering an implication about problem posing instruction for improving problem solving ability through 5th grade elementary school students' responses on problem posing. For the purpose a survey was implemented to 281 students at Busan urban area. There was a difference between the students' completeness in terms of problem posing types. They tended to make more simple problems linguistically rather than complicated problems and made problems for the equation easily. At first for the problem posing, students need to be taught to learn for making appropriate problems about an equation.

This study examined elementary students' reading attitudes to identify the state of feeling related to reading. For this, 523 elementary students from the forth to the sixth of 'model schools for reading' participated and completed questionnaires. The results show that the average score of reading attitudes was 3.8 out of 5, and there were differences between schools, gender and grade levels. Girls' reading attitudes were more positive than boys and sixth-grade students' reading attitudes were the most negative of all grades. The students' attitudes of the school which emphasized reading for pleasure were better than that of reading for academic achievement.

In this study, 10th grade students' views about the universe were surveyed and its affecting factors were investigated. Results showed that when hearing the word of 'the universe', 10th grade students considered it as 'a physical space'. Many students used 'feeling', or 'unknown space' to explain. When they portrayed the universe, many of them described it as a solar system scale. About the center and spatial limit of the universe, most students explained with the view of a heliocentric, geocentric or non-centered universe. Many students explained that the universe changed along with a direction as a physical space. These results were investigated again in different groups in terms of gender, beliefs, and familiarity with astronomy. As a result, students' models about the center, spatial limit, and the variation of the universe were different in the groups. Explanation of the origin of the universe was affected by the religious belief. Results showed that personal views of the universe are various, and many factors influence their views.

The study aimed to investigate what high-school students recognize mathematics textbooks and how they use textbooks in their learning mathematics in and out-of mathematics classrooms. For this purpose, we developed a set of interview questions in order to unpack what high-school students thought about mathematics textbooks and how they intended to use the textbooks for their learning mathematics. Eleven high-school students participated in the interview; the interview lasted for about an hour for each student. The data from the interviews were analyzed. The findings from the data analysis suggested as follows: a) the students seemed to consider mathematics textbooks as crucial medium for a mathematics classroom material and thus, they were likely to obliged to use the textbooks for preparing for not only tests and examination conducted regularly in schools but college entrance examination conducted nationwide; b) however, the students appeared to use the textbooks in limited ways in which they looked into the textbooks to prepare for mid-term or final exam only, not for their understanding mathematical contents as a main resource; and c) the students seemed to realize that they rarely have had an opportunity to develop mathematical thinking capabilities and understand mathematical ideas conceptually through the mathematics textbooks.
