Constructivist theory and teaching science in the social context are a main stream in science education. This study was purposed to introduce the STS in-service program implementing in Chonnam National University. and to analyze the results of the program in terms of changes of teachers' and students' perceptions and attitudes. The major features of the STS in-service program were as follows: teacher-centered. teaching in the social context. emphasis on constructivist approach. development of STS module and implementations. A total of 20 secondary science teachers participated in the in-service program. and filled out two questionnaires. Science Education Reform Inventory and Constructivist Teachings Survey. Three of the 20 teachers were selected to gain information from their implementations of a STS module into their respective classrooms. The students completed two instruments. Constructivist Learning Environment Survey. and Scientific Attitude Survey. The responses from teachers and students are as follows: 1. The participating teachers were very aware of the necessity of reform in science education. and the degree of the perception of the necessity increased after the STS in-service program. 2. The STS program significantly improved constructivist teaching techniques. 3. The perceptions of the students about constructivist learning environments improved significantly after the STS in-service program. 4. Students' scientific attitudes improved significantly through STS approach. The STS in-service program with the above mentioned features was found to be effective in our current school system. and could be implemented successfully if teachers were willing to learn and participate in the reforms of science education.

In this study, we tried to find the effects of carrying out infographics instruction based on visual thinking with the infographics materials presented in physics textbooks targeting specialized vocational high school students. Thus, 60 students were divided into the experimental group and the control group, the experimental group had 25 classes composed of 'infographics concept formation, infographics understanding activity, and infographics configuration activity', on the other hand, the control group were instructed by lecture-type class. The results of this study are as follows: First, features of the infographics created by the students include changes in types of presentation from 'simple arrangement' to 'simple reconfiguration' and from 'illustration' to 'comparative analysis', which were made by the visual thinking of the students activated in accordance with the increase of their configuration times. Second, instruction by using infographics, visual thinking significantly improved in the level of understanding, visibility, usability, and communicability. Third, after instruction using infographics, the mean score of the experimental group's achievement significantly improved. Fourth, there was a significant improvement in the area of 'normality of scientist, attitude on scientific inquiry, and scientific attitude' in the test of attitudes toward science. From the analysis results, we could conclude that instruction using infographics enhance students' understanding of scientific concepts and communication capability by improving visual thinking abilities, which have a positive impact on academic achievement and attitudes toward science.

We use a scale mainly for quantification when we study the psychological characteristics that we cannot observe. The utilization of a scale is frequent in scientific educational studies. The convenience offered by Likert scale, which is among the most frequently used, enable us to grasp characteristic attitude or recognition in students, and evaluate them against an affective domain. But a lot of errors occur, and has been noted as well in the case of utilizing Likert scale in the process. A central tendency in the utilization of Likert scale appears in this study, and the trend analyzes according to study objects and study contents, but we intend to find a way to utilize Likert scale. The results of study made on our countryside students show that the answers tend to get concentrated and a central tendency appears. Our countryside students were aware of the eyes surroundings them, have respect for elders through social experiences, and have had troubles with differentiated expression or personality in the group and cultural environments. According to the object of study, the central tendency appears more among older students than younger students, more among general students than gifted students. In the contents of study, the central tendency has been given more appearance in scope and their exposure has relatively been in large domain. Therefore when utilizing Likert scale in scientific education study, an error of central tendency appears as if they are results of the study. So, when applying the Likert scale to scientific study, we need to consider sociocultural environment, characteristics of an object and contexts of study. This enables avoiding dependence on numerical value of the utilization results, and interpret them correctly.

This paper was to examine the effects of university-based science gifted education program on scientifically gifted students' science problem finding ability and cognitive-affective factors. For this study, 69 scientifically gifted students with previous Silted education experiences at the university-based science gifted education centers and 91 scientifically gifted students without any previous gifted education experiences were compared. Both groups of students were currently enrolled at a specialized science high school. To compare both groups, scientific problem finding ability, science anxiety, science related attitude, self-efficacy, intrinsic motivation, test anxiety, cognitive strategies, and self-regulation were measured. The results indicate that there was no significant difference on scientific problem finding ability between these two groups. The comparison between the past and now in the aspects of variables observed in the study showed that both groups of students were decreased in the science anxiety and self-efficacy. But the test anxiety was significantly increased compared to the past in both groups. Implications of the study were discussed in depth.

In this study, a TPACK-based STEAM program was developed and applied under the theme of excretory organs in the 'Structure and Function of Our Body' of the elementary science curriculum. The program was produced and conducted through curriculum analysis and learning goal detailing, learning environment analysis, teaching·learning method and technology selection, TPACK elements arrangement and teaching·learning material development, application and effectiveness verification. Teacher's TPACK considered in STEAM program design process is content knowledge (appearance and work of excretory organs), pedagogical knowledge (STEAM, problem-based learning, research learning, discussion learning, cooperative learning, scientific writing) and technology knowledge (3D printer and smart device application technology). The program consisted of a total of 8 hours of project learning activities and was applied to 29 students in the fifth grade as an experimental group. A program of the same theme developed mainly from textbooks was applied to 27 students in the fifth grade of a comparison group. As a result of the application of the program, the experimental group showed significant improvement in creative problem-solving ability and scientific attitude compared to the comparison group, and the class satisfaction with the STEAM program was also high. However, there was no significant difference in academic achievement ability.

Based on the importance of visual representation for scientific understanding, this study applied visual thinking in elementary science classes. This study analyzed elementary students' visual thinking and investigated the instructional influences. Students' perceptions on the class applying visual thinking were also investigated. The subject were 38 fourth grade students, 18 in experimental group and 20 in control group. For the unit of 'Shadow and mirror', on-line and off-line blended classes were applied in both group because of COVID-19. The experimental group student were asked to construct their own visual thinking, while the control group students used traditional workbook. The results were as follows. First, students' visual thinking can be classified into three different types, which are 'activity recall type', 'result summary type', and 'core concept representation type' based on what they represent rather than how they represent. Second, applying visual thinking in science class showed significant effects on science academic achievement, science related attitude, and creative academic efficacy. Third, students' perceptions on applying visual thinking in science classes were very positive. Students perceived visual thinking activities were interesting and helpful for understanding science.

This study analyzed all of the research articles published in six of the Korean science education journals in the past three decades. The purpose of this research synthesis was to identify gender differences in hundreds of research articles accomplished at the personal, local, and national level that have repeatedly been reported in several international comparative studies. There were few of articles that focused on gender issues, but 279 articles presented a result of gender issues separately. Of the 279 articles, we finally analyzed 225 research articles for a statistical significance. The articles were divided into two types of research method: test-based studies and experiment-based studies. The results of research synthesis in test-based studies were as follows: The largest number of studies reported male superiority in science knowledge and science-related attitude, which is similar to the results of recent international studies. In particular, gender differences were the biggest in science-related attitudes and the least in scientific process skills. The result of research synthesis in experimental studies was that the largest number of articles did not show significant gender differences in the effect of the applied program. It is noteworthy that the applied science education programs tend to be more effective in improving female students' scientific attitude and male students' science knowledge. It is necessary to develop more gender-inclusive science programs for female students to feel science more positively.
