The purpose of this study is to examine the effects of the Portfolio applied science instruction on the students' scientific affective domain and perceptions of portfolio in elementary schools. Portfolio applied science instruction of the 6th grade science unit 'Environment pollution and Nature protection' was developed for this study. Traditional instruction was implemented to the control group and portfolio applied science instruction was implemented to the experimental group. Pretests of the scientific affective domain were administered to both groups. The treatment was given for about seven weeks for both groups. Instruments about scientific affective domain were administered to both groups. A questionnaire on perception of portfolio applied science instruction was given to the experimental group after the treatment. The results were analyzed using t-test on the students' scientific affective domain. The results of this study are as follows: 1. Portfolio applied science instruction program for elementary schools was developed. Students themselves determine the portfolio learning goal in a portfolio applied science instruction. Students construct the portfolio and they evaluate themselves and other colleagues. Also teachers go on portfolio applied science instruction considering portfolio purpose, concepts, evaluation. 2. There was not a statistically meaningful difference between an experimental group and a control group o]1 the students' scientific affective domain. In three sub categories of a scientific affective domain, the science perception, the interest on science and scientific attitude, there were not statistically meaningful difference among them. 3. As the results of the questionnaire on perceptions of portfolio, they didn't understand it very well but after learning portfolio, they showed positive attitude to perceptions of portfolio. Students in portfolio applied science instruction like more the portfolio applied science instruction than general instruction. 4. Portfolio applied science instruction has an useful value as a method of teaching and evaluation. Students and teachers can produce various portfolios products in portfolio applied science instruction. As a conclusion, portfolio applied science instruction was not statistically meaningful on the students' scientific affective domain, but it gives positive effects on perceptions of portfolio in elementary schools. Therefore, portfolio has an educational value as a method of teaching and evaluation for students' growth. In the future, teachers and students must have interaction and feedback in portfolio applied science instruction.

The purpose of the study was to investigate middle school students' and teachers' perception of psychological learning environments as well as the differences between them. This study sampled 503 middle school students and the 16 teachers who taught them. 'Psychological Learning Environment Instrument by Science Teacher' was implemented to collect data. Frequency analysis and descriptive statistics, as well as t-test, ANOVA were used for basic analysis of data. There were statistically meaningful differences in students' perception of psychological learning environments by gender, science achievement, science preference and self-efficacy in science. However, there are no differences in teachers' perceptions of psychological learning environments by gender, age, career year and major. The difference between teachers' and students' perception of psychological learning environments was not large, showing no statistical significance. However, teachers' perceptions of psychological learning environments was a little higher than that of students.

This study was conducted for the purpose of analyzing the teachers' and students' preferences and reality with regard to their interaction in secondary school science classes. The subjects of this study were 180 teachers and 1,389 students. The contents of the questionnaire for the teachers included the quality of the personal relationships between the teachers and students as well as the teachers' recognition of teaching activities, and the questionnaire for the students dealt with the quality of the personal relationships between the teachers and students as well as the students' perceptions of their classes. The questionnaire responses were divided into preferences and reality for the research. The results are as follows. First, the levels of the teachers' and students' perceptions of their interaction were significantly lower (p<0.05) compared to their preferences with regard to such. Second, the female teachers showed higher levels of preferences and reality compared to the male teachers in the case of the teacher variables, and the middle school teachers showed higher levels of preferences and reality compared to the high school teachers. Third, the male students showed a higher perception level compared to the female students, and both the preferences and reality levels of the middle school students were significantly higher (p<0.05) than those of the high school students. In addition, the level of interaction was lower in big cities than in small cities. Fourth, there was a significant difference between the levels of the teachers' and students' preferences and reality with regard to their interaction.

The purpose of this study was to examine the status and science teachers' perceptions of classes for those gifted in science in elementary school. For this purpose, a number of questions were posed to teachers : 27-item-questionnaires were given to 38 teachers of students gifted in science in elementary schools located in Incheon province. The results of this study were as follows : 1. most elementary teachers were in charge of classes containing students gifted in science, but this was the case with only a few secondary teachers. Therefore, it appears to be more necessary to educate elementary teachers who majored in science content and gifted education. 2. In addition, most teachers had positive perceptions of the needs, attitudes and environments needed for gifted education. Most of them attended 60-hour training programs on gifted education. They thought that it was helpful in understanding the characteristics of gifted students, but they wanted to learn more about actual pedagogical methods through such programs. 3. The teaching methods used in classes for those gifted in science were mainly experimental activities, but there were few opportunities for creative problem solving and project learning. This may be due to limited class time of about one hour every two weeks in this class. 4. When the materials used in class were first developed, they mainly used materials made by the city board of education and selected the theme of interest by themselves. Therefore, there may be problems of duplication of materials or systems regarding the science contents for one year. 5. Furthermore, the themes of the materials used were mostly related in terms of the contents of textbooks than more generally. When planning and managing the classes for those gifted in science, the above points should be considered in order to improve the education of those students gifted in science.

In this study, we investigated the perceptions of elementary school teachers on the use of analogy generation in scientifically-gifted education. The relationships among the perceptions and the self-perception as teacher for scientifically-gifted students were also investigated. A survey was administered to 119 elementary school teachers, and in-depth interviews with some teachers were conducted. The results revealed that the teachers had a relatively good understanding of the advantages/disadvantages of analogy generation in cognitive, affective, and learning environmental aspects. Their perceptions on the usability of analogy generation and their willingness to practice of it in scientifically-gifted education was also positive. They highly perceived on the various factors related to effective uses of it in scientifically-gifted education. Their self-perception as teacher for scientifically-gifted students was comparatively low, and significantly related with the perceptions on the advantages of it, the usability, the practical methods to use, and the various factors related to effective uses in scientifically-gifted education. Educational implications of these findings are discussed.

Since 1998, an elementary teacher education institute in Korea has hosted the center for the gifted education. The institute hired undergraduate students to escort and liaison each class of the gifted student participants with assisting classroom activities. These liaison teachers observed the gifted classroom activities and evaluated them by using a given checklist and filling out pre-made evaluation forms. Currently this system is being transferred from part-time jobs for students to earn allowance into well organized pre-service teacher program focusing on the gifted education. In other words, the purpose of system is being shifted from how liaison teachers facilitate the gifted program to how the system helps the liaison teachers to be quality teachers for the gifted who can understand what the gifted are and how to facilitate them. Analyzed were the self reports of the liaison teachers regarding their perceptions and beliefs of the gifted and their education program. It was found participant liaison teachers purposed to have more live experiences with getting along with students as well. Liaison teachers’ perceptions on establishing a gifted teacher professional education sequence were reported in this study. The potential scaffolding of the pre-service teacher education program model of the gifted education was provided as a consequence of this study.

We examined how science teachers in middle schools practiced and perceived using analogies. A survey was administered to obtain 131 teachers' responses from 22 middle schools in Seoul. Most science teachers used analogies frequently in their instructions, and had positive attitudes toward the effect of analogies. They agreed that relevant figures should be presented with analogies, analogy itself should be explained to their students, and something to mislead the students' idea should be mentioned. They also responded that they practiced so in their instructions. However, it was revealed that they neither explained a concept with several analogies nor helped students to make self-generated analogies. Their idea was that proper analogy sources and instructional models were needed for using analogy effectively in science instruction. The teachers with above masters degree explained the analogy itself, and they perceived the needs for supplements and strategies in using analogy more affirmatively. The teachers possessing modern perceptions to science instructions and students' activities rather than classical ones used analogies more frequently and effectively.

This study aims to determine the implications of the efficient and effective implementation of science core competency (ScC) education by examining the state of science core competencies derived from the 2015 revised elementary school science curriculum and analyzing teachers' and students' perceptions. To this end, this paper investigated the reality of reflecting the science core competencies of science textbooks in a group of third and fourth graders from seven elementary schools who passed the test. In addition, in-depth interviews were conducted with four elementary school teachers who participated in qualification textbook selection, and 156 elementary school students were surveyed to determine their perceptions of science core competencies. Findings showed that, first, 1,586 science core competencies were reflected throughout the textbooks, with an average of 227 per textbook and biology being the most salient area. Second, teachers did not understand the difference between previous inquiry activities in textbooks and ScC education. Third, no statistically significant differences were observed in the perceptions of male and female students on science core competencies, the highest average of perceptions being those of scientific thinking ability. From these results, this study concluded that for ScC education to be realized as a curriculum, textbooks must be organized according to the purpose of core competency education, implementing practical changes, and efforts must be directed toward changing the perceptions of individuals who deliver education.
