A Calculator-Based Laboratory (CBL) system was introduced to science teachers and their perceptions to its classroom application was assessed. A CBL survey instrument was responded by 54 middle and high school science teachers who undertook a three-hour workshop of science experiments with CBL system. There were significant differences in teachers perceptions to CBL system among gender, school level, school location, teacher's degree, and years of teaching in terms of learning CBL system, applicability of CBL system for science classrooms, and effects on science achievement. Male teachers showed significantly (p<.05) higher agreement to learning of CBL system and applicability for science classrooms than female teachers. Compared to middle school teachers, high school teachers showed significantly (p<.05) high interests in CBL applicability for science classrooms and perceptions that there will be an increase of science achievement. Teachers with 4-8 years of teaching experience also showed significantly (p<.05) higher interest toward learning CBL system and its applicability. It was concluded that science teachers perceived CBL system as a promising science teaching method in Korean middle and high schools. However, a science teacher inservice training program for CBL system should be developed in consideration of gender, school level, school location, and years of teaching.

This study examined factors influencing college science learning from the perspectives of college students and high school science teachers. Using a survey created based on focus group interviews, college science majors and high school science teachers rated various factors of high school learning that positively influenced college science learning. Findings suggested that the perceptions differed by college major: the physics major students considered math proficiency and logical thinking skills as the important factors; chemistry major students and biology major students considered English proficiency and basic scientific knowledge as the most important factors. Both college students and science teachers emphasized basic science knowledge and math proficiency. However, differences between the two groups were also found in that the students perceived more need to learn about experimentation than the teachers whereas the teachers had a priority in increasing advanced science content.

The purpose of this exploratory study was to investigate the influence of pre-service science teachers' selection of earth science I, II in the high school and their college major on their self-perceived attitude and academic achievement in general earth science lecture at university. The participants in the study were 273 who enrolled in the division of science education, college of education and took the general earth science lecture from 2012 to 2015. The data was analyzed with two-way ANOVA by using SPSS 23.0. The results indicated that there was no significant difference of students' attitude and examination difficulty in general earth science lecture between earth science major and other subject major. However, students who took earth science I and/or II in high school showed positive attitude toward the lecture and higher achievement scores than students who didn't take earth science I, II in their high school. The results of the study imply that it is essential to consider students' attitude toward science and achievement in pre-service science teacher education.

The purpose of this study was to identify the actual conditions of operation in school and investigate the perceptions of science teachers and students regarding the 7th elective-centered curriculum of high school science subjects. For this study, a questionnaire survey was conducted for the selected subjects including 127 high school science teachers and 763 high school students in their third year who had experienced the 7th elective-centered curriculum. As a result of the study, concerning the way to present the elective subjects of science, many cases were the alternative way and the group-elective way in humanity courses while natural science courses had the alternative way and the free-elective way in most cases. In other words, in many cases, the right of elective was given within a limited range. The result of the investigation on science teachers' perceptions on the elective-centered curriculum was that negative views dominated as a whole. Especially, earth science teachers showed the most negative attitudes. The number of biology and chemistry teachers who supported students' right to opt subjects were lower than that of physics teachers and earth science teachers who were against it. To help students make a right choice, many viewed that the system of the college Scholastic Ability Test should be complemented in order to prevent any disadvantage to each elective subject or that it was necessary to have systematic and realistic career education. As the result of investigating the perception of high school students in their third year regarding the elective-centered curriculum, they were usually not very satisfied with it. As the reason for it, many said the selection right was limited. Many others also expressed that there were lack of public relations and education on subjects and careers. Based on these results, limits still exist in accepting all demands although there are a lot of efforts made to smoothly adjust supply and demand of science teachers as well as students' electives in the field of school. It is considered necessary to come up with counterplan and complements to prevent basic science from being neglected or lower academic achievement in the subject of science from happening, and at the same time to harmoniously deal with supply and demand of science teachers as well as the issues of students' demands given the actual conditions of school.

The goal of this study is to examine the Integrated Science and Science Laboratory Experiments of the 2015 revised curriculum applied since 2018, and to explore ways to improve these two subjects in preparation for the 2022 revised curriculum. A survey was conducted by randomly sampling high schools across the country, with a total of 192 science teachers participating. In addition, 12 high school science teachers were selected as focus group, and in-depth interviews were conducted to investigate ways to restructure common science courses for the next curriculum. Main research results include that most schools were operated in 6~8 units for Integrated Science, and the teachers in charge of Integrated Science per class averaged 2~3 over the three years. For Science Laboratory Experiments, it has operated for a total of two semesters, one unit per semester, and it was found that several science teachers are in charge of Science Laboratory Experiments to fill the insufficient number of hours regardless of major. In the in-depth interview, science teachers argued that Integrated Science should be reduced and restructured by strengthening key competencies in preparation for the high school credit system. Based on the research results, ways to reorganize Integrated Science focused on big ideas, ways to construct common science courses based on fundamental science concepts that can guide elective courses, the necessity of career guidance through common science courses, and the necessity of strengthening teacher professionalism for teaching interdisciplinary and multidisciplinary subjects were suggested.

In the Netherlands, Streefland(Elbers, 2003) gave a solution on how teachers can help students to participate in the process of knowledge construction by investigating constructions and activities of a community of inquiry for a primary school students(between 11 and 13 years of age). In Australia, Goos(2004) analyzed the teacher's role in creating a classroom culture of inquiry, which appeared to be taken for granted by the Grade 12 group, for the Grade 11 students by classroom observation and interviews. In Korea, because of diverse obstacles with a university entrance examination, a study about teacher's role in inquiry-oriented instruction for high school mathematics schooling has rarely appeared in the literature. The purpose of this study is to investigate teacher's role for promoting and managing inquiry-oriented mathematics instruction effectively by a case study. To fulfill this purpose, we develop inquiry-oriented instruction model by investigating teacher's role as an assistant for helping students to do mathematical activity.

This study analyzed the thinking types of pre-service chemical cell chemistry teachers according to grade and tried to find out how the education for pre-service teachers had influenced their thinking types. This study found that the pre-service education had failed to form scientific conceptions. Some pre-service teachers thought that college education couldn't help them understand the knowledge about chemical cell. In addition, they are lacking in scientific conception. Even some of them who thought college education was helpful had wrong conceptions. Most of the pre-service teachers' thoughts could not exceed the level of the high school chemistry textbooks. But, Juniors had more scientific conception than other grades through the group discussions about chemistry textbooks' contents in the course of "Theory of Science Teaching Materials". So, Pre-service education should include the pedagogical knowledge with content knowledge treated in secondary school science textbooks for educational effects.

The purposes of this study are to investigate Korean science teachers' perception on the science gifted education in Korea, and to investigate if there are differences on their perception among the science teachers whose institutes are different. Their institutes are divided into three groups, which are the formal schools for the gifted in science such as Science High-School, gifted education centers attached to district education authority, and general secondary schools. For the study, 266 science teachers were sampled from the schools in Busan Metro-city, Ulsan Metro-city, and Kyoungnam Province, and then questionnaire developed by the authors were administered to them. The research results are as follows. Firstly, teachers who were going to participate in special education for the gifted in science answered affirmatively, and they thought it seemed worthwhile. On the other hand teachers who were not going to participate in it, answered negatively, mentioning shortage in specialty or extra work overload. Secondly, only the Korean Educational Development Institute was too much preferred by science teachers for teacher training institute for the gifted education in science. Therefore, it is needed to extend the teacher training institutes for the gifted education in science throughout the country. Thirdly, the perception of science teachers on the constitution of a class for the gifted in science is very different among the teachers of formal schools for the gifted in science and the teachers who teach science part time when it is needed in the district institutes for the gifted education. Finally, the perception on the aims of special education for the gifted in science is very different between the teachers who teach the gifted in science and the teachers who do not teach them.

This study focuses on the current practices and teacher's perceptions of highschool Home Economics Education in Busan, Ulsan and Kyungnam area. Data were collected from 70 teachers with the questionnaire by mail. The results were following : 1. Home Economics have been teamed at schools of class rooms mere than 31, women's high schools and public schools. Teachers more than $70\%$ have operated and lessoned with 4 or 5 among 5 sectors of subject matters, especially emphasized family${\cdot}$human development and food${\cdot}$nutrition sectors. The most difficulties were the shortages of student's interest and reference books. 2. Teachers have cognized highly the connection of Technology${\cdot}$Home Economics and Home Economics, but evaluated lowly the job-course education among the H.E's goals. 3. Necessities of HE were evaluated highly, but student's interests by teacher's judgement lowly. Manual theses of clothing${\cdot}$textile and housing sectors have needs to alter partly. 4. Subject matters to add for the near future revision were related to dissatisfaction of H.E's matters. Teachers cognized problems about the excess, overlap, old-fashioned and irrelevant deepen levels of subject matters.
