The purpose of this study was to analyze 9th grade students' understanding about the earth science terms written by Chinese characters depending on their loaming style and attitudes toward science. The study selected the eight students with the middle level of science achievement and divided into four groups: verbal-high attitude toward science, verbal-low attitude toward science, visual-high attitude toward science, and visual-low attitude toward science learners. Three types of questionnaires including Korean characters type, a picture type, md Korean and Chinese characters type were developed to determine the students' understanding about the earth science terms written by Chinese characters. The results of data indicated that the 9th grade students' understanding showed no significant difference by their different teaming style, and yet demonstrated higher level of understanding in Korean and Chinese characters type questionnaire rather than Korean characters type only or a picture type. On the other hand, the level of students' understandings both in Korean characters type and a picture type was about equal. In conclusion, it seems more effective in students' teaming about the earth science terms written by Chinese characters when they were provided with both Korean and Chinese characters.

The purpose of this study is to explore the science learning motivation of technical high school students through comparison with general high school students. 596 high school students and 1063 general high school students participated in the study. Three statistical methods were used for data analysis: two-way ANOVA, independent sample t-test, and Pearson correlation analysis. The results showed that the interaction between school type and grade had a significant effect on the difference of students' motivation for science learning. There was a significant difference in learning motivation among general high school students according to academic year, while there was no significant difference between first and second grader of technical high school students. Especially, technical high school students showed low level of science learning motivation compared to the students in general high school. The correlations among five motivational factors of science learning motivation were also significantly lower than that of general high school students. Lastly, the result of correlation analysis between science motivation and academic achievement showed that second year students in technical high school had less correlation coefficients than the first year students. Given these results, it is necessary to develop a educational strategy for enhancing science learning motivation of technical school students. We will discuss the direction of science education for technical high school based on our findings.

By PISA 2007, TIMSS 2011, Korean high school students had high academic achievement to science and mathematics, while they had low attitude. Prospective college students are increasingly avoiding natural science and engineering. Moreover, the opportunities to learn to computer science in middle and high school are disappeared rapidly. The necessity of STEAM program based on Physical computing arise under these situation. Therefore, we developed STEAM program and studied the effects of the program in 2012. The result showed that students' scientific interests and attitude, scientific problem solving ability, scientific creative problem solving ability, personality test for children, and satisfaction of school life were enhanced. This study is follow-up study for the same students who improved every domain of the measurements. They were administerd pre-test at start of 2012, post-test at end of 2012, and delayed post-test at the end of 2013, on same test. The result of the study showed that only attitude to Scientific Inquiry was enhanced, but there was no significant result on the other domain of the test in comparison with start of 2012. But this result demonstrate the effect of STEAM education conversely.

Purpose : In an attempt to analyse gender-egalitarianism related to the general characteristics, sexual consciousness and behavior in middle school students, this study was carried out. This study will provide data that can be used to develop sexuality education programs on the basis of gender-egalitarianism. Method : The subjects were 141 students (70 boys and 71 girls) in 4 classes that were randomly selected from among 8 classes of first graders in a coeducational middle school, in Seoul. For the evaluation of gender-egalitarianism, a Gender Egalitarianism Scale modified by the researcher was used. Results : Major findings were as follows: 1. Gender-egalitarianism was significantly higher in girls compared with boys. All of the boys and girls, had high gender-egalitarianism in the aspect of woman's ability in groups without sexual discrimination, but low gender-egalitarianism in woman's sexual conversation and style of dress. 2. Gender-egalitarianism in boys who had experienced intersexual physical contact, categorized as holding hands, embracing, kissing, and petting, was significantly higher when compared with inexperienced boys. 3. Gender-egalitarianism significantly increased as the father's education level increased as well as the father's open-mindedness. Factors influencing gender-egalitarianism was social acceptance, the mass media, the attitudes of the school teachers, and the attitudes of older and younger student in school. Conclusions : Based on these results, boys' gender-egalitarianism was lower than that of girls. Systematic education on gender-egalitarianism, combined with sexuality education, is necessary for middle school students, especially boys. In the long term, social acceptable the, mass media, school and home life should be changed for the achievement of the equality of the sexes.

In recent days, the Non-Linear Editing is mainly used in the field of broadcasting. In comparison to conventional editing, Non-Linear Editing can immediately access the image of the desired position and facilitate the insertion and deletion of video frame. Furthermore, it directly apply a title and transition effect to video frame. Moreover, it has an advantage of preview and easy modification in title effect, transition and editing prior to export. However, students who learn Non-Linear Editing first time are not easy to learn it. In this paper, we propose a new learning model based on Reciprocal Peer Teaching (RPT), which helps NLE beginners to understand Non-Linear editing more clearly. We divide the students into two groups i.e. control group and experimental group. The control group students do not apply proposed method while experimental group performs evaluation over our model. Furthermore, we carry out the experiments, which include the overall average of the two groups, academic achievement of students with low grades, standard deviation, T-test and satisfaction surveys. The experimental group shows the superiority in performed experiments and higher satisfaction ratings than the control group.

The purpose of the present study is to find out some implications from comparing mathematical education of Israel and Singapore. This study examined what values are represented in schooling of both Israel and Singapore and what factors are influencing mathematics teacher education of both countries. Education in Israel and Singapore plays a significant role for the survival of the nation and economic success, and the education system is focused on elitism, especially in terms that they have selective system of students and restrictive exams from the elementary school level. The educational system in both countries provides students with little opportunities for social mobility, because students from the low SES families are not equally exposed to educational facilities and experiences. The results of this study imply that the critical factor affecting students achievement in Israel and Singapore seems to be the quality of teacher education system and the quality of teachers. In particular, it seems that we need to be very careful of uncritically adopting mathematical ideas from both Israel and Singapore, because they both have very different contexts of educational goals, educational policies, racial and cultural factors from Korea.

In this research, we observed how students perform as they followed the teachers' instruction, and consequently perform their realized potential. As the accountability of school education is emphasized, various attempts try to disconnect the vicious cycle of producing low achievers. Efforts are allocated into developing a method to minimize cumulative effect of the lag in educational benefit by focusing on the elementary education. Based on the 2007 revised curriculum, mathematics achievement level and assessment criteria were developed. These criteria were used to standardize the course and assessment objectives for 4th through 6th grade students' mathematics studies, and to assess lower performing students and the lag in their mathematical understanding. The educational materials and assessment criteria can be expected to lead lower performing students by giving them the personalized lesson plans to minimize the lag of mathematical understanding, and eventually expedite their progress and prevent cumulative effect of the lag in the following curriculum.

This study compared 14 programs for the economically disadvantaged or minority students with potentials in 5 countries - US, UK, Germany, Australia, and Israel, attempting contents and characters of Korean Head Start to be developed, that is the program for economically disadvantaged gifted students or students from multi-cultural families, who are gifted at risk of under-representation and under-achievement. School wide enrichment programs, which served all students with gifted programs, using RTI model in the pursuit of equity and excellence, turned out to be effective as early interventions and identification implemented for economically disadvantaged or minority students with potentials. Gifted programs for low Social Economic Status (SES) or minority students played a role as a bridge for disadvantaged students to get into a regular gifted program or even higher gifted schools and to have a competency to compete with affluent gifted students. The principles of the programs were acceleration and differentiation. Most programs also ran a parents' education and a mentor program to motivate and support disadvantaged students socially and emotionally. Collaboration among governmental offices and usage of external resources were more effective to support these students and the programs.

The purpose of this study is to explore ways to improve the quality of real-time video lectures in a non-face-to-face environment using IPA (Importance-Performance Analysis). Recently, due to the impact of COVID-19 in universities, all remote classes are being implemented, so research is needed to raise learner awareness. Accordingly, factor analysis, mean analysis, correspondence analysis, and IPA analysis were performed based on the data of 632 students who responded from March 21 to June 30, 2021 for learners of K University in Chungbuk. First, overall satisfaction was low compared to importance, and the difference in system perception was the largest. Second, the difference in learner perception of real-time video lectures through the IPA matrix showed that the system error and screen cutoff were the largest. Third, the difficulty of lecture content, task and test feedback, etc. are classified. Accordingly, the satisfaction of real-time video lectures in non-face-to-face environments is low, suggesting that school-level support for quality improvement to improve learner satisfaction in non-face-to-face environments and the role of instructors are needed to improve learners' academic achievement.

We analyze the admission test problems used in 1998 at the Science Education Center for Gifted Youth at Kyungpook National University (SECGY, KNU). The test consists of two parts, an evaluation of the scientific thinking skills and an evaluation of the achievement for Mathematics and Sciences, the former of which includes evaluations of scientific process skills and logical thinking skills. The problems for the test of scientific thinking skills were developed and standardized by the Korea Education Development Center, while those of the achievement for Mathematics and Sciences were made at SECGY. We calculate the indices of the difficulty and discrimination for each problem to determine whether or not the test is appropriate to apply for selecting number of gifted students among the recommended students from 389 middle schools in Taegu-city and Kyungsang-pook-do Province. We find that both indices of most problems for the test of scientific thinking skills were out range of the appropriate level and. moreover, even those problems which fall into the appropriate range showed very low efficiencies for distractors. We, thus, conclude that the problems of the test of scientific thinking skills are inappropriate to use as a test for admission to SECGY. On the other hand, the problems of the achievement test showed extreme results; the Mathematics problems appeared to be too difficult, whereas the Physics problems appeared too easy. However, overall scores showed a normal distribution, indicating that those problems played crucial role in selecting gifted students. We finally propose several suggestions in developing the test problems and in selecting students at the SECGY.
