The purpose of this study is to investigate preservice secondary mathematics teachers' knowledge about graphical representation and provide implications for better mathematics teaching and learning in our schools. For this purpose, sixty-three preservice teachers were selected and given diverse graphical representation problems of y=1, y=x, x=0, $x^2+y^2=1$. All preservice teachers completed two types of questionnaires. First type is about constructing the graphs of the above each equation, and the second one is to make them find the appropriate graphs from given examples of the each equation. The results indicated that all the participant pre service teachers were unable to construct graphs in terms of various dimensions and various direction of coordinate axis. All of the participants represented the graph of each equation on only two-dimensional coordinate system. In addition, some preservice teachers believed that the axis of coordinates have to be x-axis on horizontal line and y-axis on vertical line. From this study, it is implicated that pre service teacher education program needs to provide the experience of representing the graphs of equation in terms of various dimensions and various direction of coordinate axis so as to develop their future students the flexibility and creativity in mathematical thinking especially in the area of space perception.

This study investigated high school students' perception of English extensive reading (ER) after introducing ER to general high school students in a metropolitan area. In addition, as the free semester system was expanded in high schools as well as middle schools, we developed a class model for English extensive reading. 91.4 percent of the students who participated in the study said that they wanted to try using the English extensive reading method. Also 35 high school students who experienced English extensive reading chose the 'Five Finger rule' and 'Graded Readers' Series' as the most helpful factors in their extensive reading experiences. In interviews with English teachers, teachers expressed their demand for the development of a model of English extensive reading suitable for free semesters in general high schools. This study proposes an English extensive reading class model utilizing library resources that can be used in the free semester system as well as a performance assessment-oriented English extensive reading class model.

This study aimed at investigating the perception and action plans of the school breakfast program (SBP) proposed by nutrition teachers and dietitians at elementary, middle, and high schools in Gyeongbuk province. The survey was carried via questionnaires throughout April to May 2010. Two hundred ten questionnaires were returned (52.5%) and out of the total, 194 were used for analysis. Of the respondents, 73% disagreed and 27% agreed to the implementation of SBP, although most respondents agreed to the importance of eating breakfast in children. The percentage of disagreement was higher among subjects with working experience of 15 years and more, age of 40 years and more, and those who were employed at elementary schools. The primary reasons of disagreement were 'eating breakfast with family is better' and 'it increases the cost of school foodservice'. The respondents preferred students' optional participation (62.9%) over universal participation (37.1%) of SBP. Action plans of SBP, which were proposed by nutrition teachers and dietitians, included direct operating system by the school, food delivery schedule prior to the day of serving, 2-3 hours of preparation time, serving food 50 minutes before the start of classes, and convenient style menu served at the school cafeteria. Efforts to lessen foodservice employees' workload as well as support from school principals and the Office of Education were suggested as prerequisites for a successful SBP implementation.

This study is to examine the perceptions and attitudes of parents about the teachers' recommendation system through their observations to identify the gifted. We conducted surveys for parents who had elementary school children in Busan metropolitan city and analysed the results to find out about the differences among parents groups in terms of their monthly incomes and opinions on teachers' observation and nomination for the gifted. The results are following; First, approx. 80% of the respondents recognized the changes in the giftedness identification system. Also, 40.5% of the parents positively thought about the teachers' observation and nomination system (positive group), whereas 32.3% of the parents showed their negative opinions about the system (negative group). There were also 27.2% of the parents who did not make their decisions (no-decision-making group). Second, most of the parents accepted that the teachers who were professionally trained in gifted education should be the persons for observing and nominating gifted students. However, significant differences were shown among the different monthly income groups of the parents in regards to who should be the person taking charge of recommending the gifted and how trustworthy this person could be. Third, the positive parents' group mostly expected that as the teachers' observation and nomination system is adopted, expenses for private education would decrease, whereas the negative group and no-decision-making group thought that the opposite result would occur. These results will be helpful for the successful adoption of teachers' observation and recommendation system to identify the gifted in the field of education.

This research analyzed elementary pre-service teachers' perception on the importance and performance of major factors that constitute good instruction, and attempted to find ways to improve pre-service teacher education. A survey was conducted to 157 pre-service teachers who were senior students at a university. The questionnaire consisted of four main areas of good instruction and major factors for each area, and the importance and performance of each factor were answered on a 5-point scale. As the result of the t-test on the difference between importance and performance, significant differences were found between the importance and performance of all 24 factors. In addition, the importance-performance analysis showed that there were 3 factors to be concentrated for the improvement, 9 factors to be kept up because of their good work, 9 factors to have low priority, and 3 factors to avoid excessive effort. Based on the results, the research proposed issues to be considered in organizing and operating the elementary pre-service teacher education program.

It is important to understand how pre-service teachers perceive e-learning because their prior-experience with e-learning will have a great impact on their teaching after the graduation. Pre-service teachers (401 students) with cyber learning experience, which is a form of e-learning, were selected in 2004 in May and June. Survey was conducted regarding the instructional experience (working hours, tasks and evaluation, satisfaction about cyber learning and its academic achievement, difficulties and suggestions) and instructional methods (instructional activities, frequencies of interaction, strategies of interaction, collaborative activities, behaviors in the group instructional activities for knowledge development). The results are pre-service teachers tent to spend similar v slightly less working hours for cyber learning, similar or slightly less satisfaction level for the instruction and the academic achievement. It was interesting that female students were more negative than males students, considering female students have been more active in online discussion traditionally. Logical presentation of contents and instructional strategies for the cyber learning were the most wanting suggestions. E-mails and BBS for reference materials were the two most used functions in the online learning. The amount and types of tasks were satisfactory. Students did not interact freely during the group activities, they reported they did not learn much through the group activity. During the group work, they consider they do their roles with responsibility while they have slightly negative responses toward other members' contribution in the group activity. Off line meeting is strongly suggested.

The purpose of this study is to investigate earth science pre-service teachers' perceptions and educational utilization of geoparks. It is intended to provide implications of geopark education in the current curriculum and effective geopark education. Education using geoparks has the effect of helping students cultivate inquiry and learning skills, enhancing students' participation in classes. To provide education with these results, it is necessary to deliver meanings of the geopark education to of earth science pre-service teachers who will educate future generations. However, despite the advantages and needs of geopark education, earth science pre-service teachers lack an understanding of geoparks. In this study, 56 pre-service teachers enrolled in earth science education at a university in Gyeongsangbuk-do were investigated for: their perception levels of geoparks, experience, necessity, and learning method of geopark education. As a result, earth science pre-service teachers were well aware of the geoparks, but they lacked knowledge of domestic and global geoparks, confirming the need for geopark education. Currently, the degree of geopark education in the secondary curriculum is insufficient, and earth science pre-service teachers feel the need for it. However, since the understanding of geopark is lacking, support for geopark education is needed. Earth science pre-service teachers being positive about the need for geopark education, it is expected that geopark education will be active in the field of earth science, social, and comparison education when they become teachers in the future.

The goal of this study was to discover factors of difficulties on learning Brønsted-Lowry acid and base focusing viewpoint of each definition. To achieve this, we were targeting statement of textbooks and perception of teachers that have a decisive effect on students' learning. Analysis of textbooks was performed for chemistry I of high school and EBS(total 6 textbooks) which dealt with Brønsted-Lowry definition. And a survey was conducted on 24 science teachers who had Brønsted-Lowry definition teaching experience. According to the textbooks analysis, characteristics of statement way were (1) statement without viewpoint of each definition, (2) convergent statement to Arrhenius. And features of teachers' perceptions were (1) teachers who have the only one viewpoint, (2) teachers with unawareness on coexisting reason of various definitions. All of these can be explained by absence from understanding viewpoints of Arrhenius and Brønsted-Lowry. To promote students' Brønsted-Lowry learning, students should obtain viewpoints of each definition. So we suggest that pre-service teacher training curriculum and statement way of textbook should reflect viewpoints of each definition.

Acceleration of the pace of life, increasing the amount of information, the emergence of "clip way of thinking" as a phenomenon has led to the problem of choosing forms of presentation of educational materials to students. One of the ways to solve this problem is to use the means of visualization of information flow, forasmuch as the thinking of modern youth is more effective in perceiving visual images than verbal means. The purpose of the research is to prove the effectiveness of the use of visualization in the process of teaching Ukrainian as a foreign language to students with clip way of thinking. The following methods have been used, namely: analysis, synthesis, comparison, systematization and generalization of scientific literature; testing and surveys; pedagogical experiment; quantitative and qualitative analysis of data, interpretation and generalization of the research results. The essence of visualization means has been revealed; the expediency of their use in the methodology of teaching foreign students the Ukrainian language has been substantiated. It has been proven that the role of Ukrainian teachers lies in taking into account all new trends in teaching, integrating computer perception of information by foreign students into teaching technology and using cognitive visualization in order to intensify the learning process.

The purpose of this study is to find out what mathematical situation means, how to pose a meaningful situation and how situation-centered teaching could be done. The obtained informations will help learners to improve their math abilities. A survey was done to investigate teachers' perception on teaching-learning in mathematics by elementary teachers. The result showed that students had to find solutions of the textbook problems accurately in the math classes, calculated many problems for the class time and disliked mathematics. We define mathematical situation. It is artificially scene that emphasize the process of learners doing mathematizing from physical world to identical world. When teacher poses and expresses mathematical situation, learners know mathematical concepts through the process of mathematizing in the mathematical situation. Mathematical situation contains many concepts and happens in real life. Learners act with real things or models in the mathematical situation. Mathematical situation can be posed by 5 steps(learners' environment investigation step, mathematical knowledge investigation step, mathematical situation development step, adaption step and reflection step). Situation-centered teaching enhances mathematical connections, arises learners' interest and develops the ability of doing mathematics. Therefore teachers have to reform textbook based on connections of mathematics, other subject and real life, math curriculum, learners' level, learners' experience, learners' interest and so on.
