For teachers to develop new beliefs regarding science teaching and learning, they must undergo a process similar to what they are trying to provide their students. Seventy-one Korean secondary school teachers including 20 earth science teachers have participated in such process. In the four-week long summer workshop hosted by University of Iowa, science teachers were exposed to several activities and lectures wherein they experienced student-centered lessons by playing the roles of both teachers and learners. This study examined the influence of such experience on the teachers’ beliefs about science teaching and learning. Changes in teachers’ beliefs were found in seven question items on the subjects of goals of science learning, the roles of science teachers and students, and classroom practices after workshop participation; it was found that teachers’ beliefs of science learning and teaching shifted from teacher-centered to student-centered. Although this shift does not denote a complete shift from one extreme to the other, it is meaningful to note that teachers’ beliefs after attending the workshop were interpreted to be either anti- or contrary to teacher-centered. One of the possible factors for making such positive changes may have been teamwork or the teachers’ cooperative learning experience.

The purpose of this study was to examine the types and characteristics of the knowledge constructed by pre-service secondary science teachers. Data included 26 student-teachers' narratives regarding their experiences in teaching high school students who were enrolled in extra-curricular science classes. It was revealed that the pre-service teachers awoke to the importance of subject matter knowledge, and learned it themselves in the situation of their own teaching. Especially their concern about science content knowledge was strongly associated with the matter of didactic transposition of the knowledge. The result also showed that the pre-service teachers constructed knowledge about the relationship with students as well as pedagogical knowledge to help students learn, and that they newly realized the nature of science in the context of teaching science. In addition, the teaching experiences allowed for the student-teachers to develop knowledge of oneself as a teacher and knowledge about science education in schools. It was believed that the knowledge constructed personally by the pre-service teachers from their teaching experiences could be a platform for the development of teacher expertise. Implications of the present study for science teacher education and relevant research were discussed.

The purpose of this study was to examine the perceptions of novelty space among pre-service elementary and secondary earth science teachers. We conducted a survey to explore the perceptions of 38 pre-service elementary school teachers at the National University of Education and 31 pre-service secondary earth science teachers at the Department of Earth Science Education at B University. Semi-structured interviews were conducted with 12 participants, including three pre-service elementary teachers and nine pre-service secondary science teachers. In addition to the elements of novelty space, prior knowledge (cognition), prior outdoor learning experience (psychology), familiarity (geography) with outdoor field learning, and social and technical elements were added. When classified based on elementary and secondary levels, there were statistically significant differences in cognitive, psychological, geographic, and social areas for the elements of novelty space. Statistical differences indicated that the experience or capital related to outdoor learning may have resulted from more pre-service secondary earth science teachers than pre-service elementary teachers. In additional interviews, both elementary and secondary pre-service teachers reported that competencies in the technical domain would be emphasized in the future owing to the necessity and the technical development of virtual-reality-based outdoor field learning programs. This study emphasizes the academic significance of novelty space that should be considered to conduct geological field learning for elementary and secondary earth science pre-service teachers while considering the current post-pandemic educational context.

The purpose of this study was to investigate the teachers' recognition on the optimization of the educational contents of Clothing & Textiles in subjects of :he Practical Arts or the Technology & Home Economics in the course of elementary, middle and high schools. The statistical data for this research were collected from 203 questionnaires of teachers who work on elementary, middle and high schools. Mean. standard deviation, percentage were calculated using SPSS/WIN 12.0 program. Also. these materials were verified by t-test, One-way ANOVA and post verification Duncan. The results were as follows; First, The equipment ratio of practice laboratory were about 24% and very poor in elementary schools but those of middle and high school were 97% and 78% each and higher than elementary schools. Second, More than 50% of teachers recognized the amount of learning 'proper'. The elementary school teachers recognized the mount of learning in 'operating sewing machines' too heavy especially, the same as middle school teachers in 'making shorts': the same as high school teachers in 'making tablecloth and curtain' and 'making pillow cover or bag'. Third, All of the elementary, middle and high school teachers recognized the levels of total contents of clothing and textiles 'common'. The 80% of elementary school teachers recognized 'operating sewing machines' and 'making cushions' difficult especially. The same as middle school teachers in 'hand knitting handbag by crochet hoop needle', 'the various kinds of cloth' and 'making short pants'. The same as high school teachers in 'making tablecloth or curtain'. Fourth, Elementary school teachers recognized 'practicing basic hand needlework' and 'making pouch using hand needlework' important in the degree of educational contents importance. Middle school teachers recognized 'making short pants unimportant. High school teachers considered the contents focusing on practice such as 'making tablecloth and curtain' and 'making pillow cover or bags' unimportant. My suggestions were as follows; Both laboratories and facilities for practice should be established for making clothing and textiles lessons effective in Practical Arts in elementary schools. The 'operating sewing machines' which were considered difficult should be dealt in upper grade, re-conditioning to easier or omitted. The practical contents should be changed to student-activity-oriented and should be recomposed in order to familiar with students' living. It was needed to various and sufficient supports for increasing the teachers' practical abilities.

The purpose of this study was to explore high school teacher's and students' perceptions of learning difficulties of the ‘chemical bond' unit of the Chemistry II in the 7th national curriculum. The participants in this study were consisted of a teacher and his students(85) from the Chemistry II classrooms: they all answered to the questionnaire, and then some students and the teacher were interviewed individually. The results showed that there were big differences between the teacher's and his students' perceptions of 1) the most difficult unit for understanding; 2) concepts they learned; and 3) the most difficult concept for understanding in the classroom. Students thought that electro-negativity unit was the most difficult to understand while teacher thought molecular structure unit was the hardest unit to teach. And teacher taught all 32 subjects of chemical bond unit to students, but some students could not remember they learned all of them. Most difficult parts for students to understand were ‘Coulomb force' and ‘dipole moment', while the most difficult part for the teacher to teach was ‘the conceptual difference between atomic bond and intermolecular force'. The reasons caused the students' learning difficulties were analyzed and discussed based on the interview data, and then further study was presented.
