This research was developed to investigate the apprehension of the ideal image of science teacher and the view of science teaching profession. The samples were drawn from middle/high schools students, university students of colleges of education, science teachers of secondary schools. principals of middle schools and masters of high schools, and professors majoring in science and/or science education. Data were collected through the use of questionaires. The samples responded differently to the Questions depending on their personal needs and professional viewpoints. Very few of the students wanted to be a science teacher in the future. Even the many numbers of college students gave up becoming a science teacher. Furthermore greater portion of science teachers were not satisfied with their profession as science teaching. More findings are described in the paper.

This study examines how practical work in science was introduced in British schools and became an important part of school science activities during the second half of the 19th century. Firstly, the establishment of a national education system in Britain is reviewed. Secondly, a general development of school science teaching is summarized with a special attention to students' enrollment in science subjects. Thirdly, the practical work in elementary schools are discussed in relation to the introduction of Object Lessons in curriculum. Then, the situations of practical work in science in secondary schools, particularly in Organized Science Schools and some famous public schools, are illustrated. Finally, the overall development until present days is critically discussed in relation to the types and aims of practical work in science.

This study aimed to explore influences of parental science attitudes and trust perceived by children on their science self-efficacy. In oder to accomplish this purpose, a quantitative research was carried out for elementary gifted and general students using correlation and multiple linear regression analysis. The results were as follows. Firstly, children's science self-efficacy was positively correlated with parental science attitudes and trust perceived by both gifted and general children. Secondly, in the case of gifted children, their science self-efficacy was meaningfully affected by mother's trust, mother's science attitudes, and father's science attitudes perceived by them in that order. On the order hand, general children's science self-efficacy meaningfully affected by mother's trust and mother's science attitudes perceived by them.

The purpose of this study was to examine the perception of students about pseudo-science in consideration to their personality traits, cognitive style, and awareness of the nature of science, which might all have a great impact on their behavior and thinking. The subjects of this study were 129 sixth-grade school children in a small urban community in Gyeonggi province. The way they looked at pseudo-science was investigated after three kinds of traits were selected as variables, including personality traits, cognitive style, and awareness of the nature of science. Four different instruments were utilized, which respectively covered personality traits, cognitive style, awareness of the nature of science and perception of pseudo-science. The results of the study were as follows: First, the children with higher emotional stability and liveliness showed higher permeability towards pseudo-science, while made no significant difference on their view of pseudo-science. Second, their cognitive style made no significant difference to their outlook on pseudo-science. Third, as for link between awareness of the nature of science and pseudo-science, the students with a poor understanding of the nature of science were significantly different from those who had a better understanding of it in perception of pseudo-science(p<.05).

과학영재 학생의 과학학습에 대한 개념을 알아보기 위해 COLS와 ALS 설문지를 이용하여 비교, 분석하였다. 과학영재 학생은 일반 학생과 과학학습에 대한 개념에 차이를 보이는데, 과학영재 학생은 과학학습을 과학 지식을 얻고, 과학 지식 구조를 확장해 나가고, 세상을 보는 새로운 관점을 얻는 활동이라고 인식한다. 과학영재 학생은 성별과 과목 선호도에 따라 과학학습에 대한 인식 및 접근방법에 의미 있는 차이는 보이지 않았다. 이 연구의 결과는 과학영재 수업을 위한 교재와 교수법에 도움이 될 것으로 예상한다.

A new spray chrysanthemum cultivar 'Prima Donna' was released by National Institute of Horticultural and Herbal Science (NIHHS), Rural Development Administration (RDA), in 2008. The cross was made between 'Plano' and 'Yeonja' in 2005. Trials were conducted from 2006 to 2008 for the evaluation and selection of this cultivar, including shading cultures in summer and retarding cultures in spring. The natural flowering time of 'Prima Donna' is late October, but year-round flowering is possible by photo-periodic control. The cultivar has single type flowers with pink petals, green center and good inflorescence. The growth of plant is very vigorous. The diameter of flower is 7.0cm. The number of flowers per stem and petals per flower are 13 and 42, respectively. Days to flowering under the short day treatment is about 59 and its vase life is 26.1 days in autumn season.

The purpose of this study was to investigate the effects of writing science diary on science learning motivation, science academic achievement and ecological sensitivity of elementary students. Teaching unit was focused on 'The structure and function of plants' in 6th grade science text book. The subjects of study were 51 students of two classes. One class of 25 students, experimental group, wrote science diaries as homework. While the other class of 26 students, comparative group, performed homeworks with fill-in-the-blank worksheets. The results of this study can be summarized as follows: First, writing science diary had a meaningful effect on improvement of science learning motivation. Second, writing science diary had a meaningful effect on improvement of science academic achievement. Third, writing science diary had a meaningful effect on improvement of ecological sensitivity. And we could find that students had a favorable impression and high satisfaction level about writing science diary from the questionnaire.

The purpose of this study was to examine the status of the field application of the Science II career electives with the application of the 2015 revised curriculum up to the 3rd year of high school. This study focused on examining high school science teachers' perceptions of the student-participatory class and process-centered assessment in Science II subjects, which are career-intensive high school science electives. A total of 192 science teachers responded to the survey questionnaire, and 12 teachers participated in interviews. In the in-depth interviews conducted to supplement the survey results, questions were asked about changes in the overall class, the status of student-participatory classes, and changes in the assessment of Science II subjects due to the emphasis on process-centered assessment. The main research results included teachers' perceptions of changes in teaching and assessment methods with the application of the revised curriculum, the degree to which the eight skills used in Science II classes develop the key competencies of science, and the teaching and assessment methods commonly used in Science II classes. Science teachers generally agreed with the purpose and necessity of introducing student-participatory classes and process-centered assessment, which are the core purpose of the 2015 revised curriculum. However, they had difficulties in practice due to the excessive content of Science II subjects. Problems were also encountered with securing objectivity and fairness during assessments and the operation of online science classes due to COVID-19.
