We have investigated the 6th middle school science curriculum and its implementation based upon the results of middle school science teachers' and professors' ratings and self-reportings. The national-wide survey was administrated to obtain the data from 213 teachers of 112 middle schools and 43 professors of colleges of education. The survey items correspond to four stages of science curriculum. In the stage of the planned science curriculum, 'goals', 'framework of contents' and 'contents' are relevant to the basic guideline for curriculum revision, 'the more emphasis on inquiry activities'. However, the amount of contents is not appropriate, and 'methods' are difficult to attain. In the stage of the written science curriculum, 'goals', 'framework of contents', 'contents', 'methods' and 'evaluations' are not useful for teachers to teach science. In the stage of the implemented science curriculum, a small number of teachers use the issues of local community, organize the different group activities, develop assessment tools cooperatively, and conduct a lesson and a program considering students' diversities. This is partially because of the large amount of learning contents, the lack of materials and the weakness of supporting system. Finally, in the stage of the attained science curriculum, the students' achievements under the 6th curriculum is not higher than those under the other curricula.
This study presents how the engineering ethics instructional modules have been developed based on Korean culture and how they are implemented into the existing engineering curricula at Sungkyunkwan University. The engineering ethics instructional modules were designed to be taught by engineering faculty members who did not have any teaching experience in ethics. As a result, it was determined that the engineering ethics instructional modules should include a detailed instructor lesson plan and all supporting resources such as slides (Power Point base), and handouts, or assessment units (pre- and post-test). Two 75 minute modules developed in this study consist of the diverse instructional activities for various student group sizes. In order to improve students' interests and classroom attention, various visual and audio resources such as famous movies, cartoons, and poems were included in the instructional resources. In addition, a number of case studies which might happen in the students' daily lives were chosen. The resulting ethical module No. 1 has been instructed in the existing engineering classes during the 1st semester in 2007. Overall, the students reported positive impressions of the modules and the faculty members also reported favorable perceptions of the modules. Also, team based activities encouraged students to participate in constructing the event trees, which are a basic analysis tool for ethics case studies. The results of this study will provide a guideline of implementing engineering ethics into the engineering curricula to other engineering programs and schools.

This study dealt with two case studies of the development of beginning science teachers' pedagogical content knowledge (PCK). This study was grounded on the idea that teacher thinking and classroom behavior are related to each other in a reciprocal way. Teachers' PCK influences teaching practices, while in a reverse way teaching activities influence teachers' practical knowledge. Two beginning science teachers participated in this study. Data collection consisted of classroom observation, interviews, reflective journals and lesson plans. For data analysis, we conceptualize pedagogical content knowledge for science teaching as consisting of four components: (a) knowledge about science matter, (b) knowledge about students' understanding of science topics, (c) knowledge about instructional strategies for teaching science, (d) knowledge about assessment in science. The outcomes of this study revealed that there was a large gap between beginning science teachers' intentions for teaching science and their practice. To give beginning teachers more opportunities to incorporate their knowledge base for teaching, we propose that they need to be involved in a real teaching situation at schools rather than in the university.
The purpose of this study were to develop of courseware using scaffolding strategy and to investigate the effect of courseware instruction upon students' conceptual understanding and affective domain including effort and self-checking. 10th grade students in the experimental and control groups were selected from high school at Cheongwon-gun in Chungbuk, and taught about chemical reaction rate for 3 class hours. The students in the experimental group studied individually through courseware using scaffolding strategy and worksheet and teacher-centered expository lesson was used in the control group. Prior to the instructions, test specification for problem-solving assessment (TSPSA) was administered and the scores of the previous science achievement test were obtained. After the instructions, the posttest on conceptual understanding and TSPSA were administered. Results of this study revealed that the mean score of the experimental group in the conceptual understanding test was similar to that of the control group at statistically significant level. This result implies that the courseware using scaffolding strategy could be a tool of the individualized instruction. The experimental group improved significantly better in three components of the TSPSA such as effort, self-checking, and cognitive strategy. From this result, it is considered that learners' self regulation is improved by being taken over responsibility of learning. So, it is suggested that instruction using scaffolding strategy is needed in science class to improve self-leading learning ability.

This study investigated the change of pre-service elementary teachers' professional visions through video-based reflection on science teaching with focus on their attention and pedagogical reasoning about student learning. Specifically, we compared two reflection cycles before and after pre-service elementary teachers went through the collaborative video-based reflection process in a professional learning community. The primary data were collected from eight pre-service elementary teachers and included their science lesson plans, videotaped lessons, video-reflection papers, and transcripts from the interviews. Pre-service elementary teachers' attention was categorized in five aspects: classroom management & control, teacher's instruction, students' thinking & learning, subject knowledge, and assessment. The level of their pedagogical reasoning about student thinking and learning was determined with six levels based on the number of evidence, evidence area, and evidence type. The findings revealed that 1) individual reflection is not enough - collaborative reflection is essential to change their attention toward students learning and thinking 2) pedagogical reasoning levels increase gradually throughout the individual and collaborative video-based reflection processes. The participants not only attributed student learning solely to the characteristics of students but also connected it with their own instruction or science content knowledge and used different types of evidences as they went through two reflection cycles. Implications for using video in the teacher education program were discussed.

This study aimed to analyze cases of online class design by pre-service science teachers to identify the teaching strategies employed for online classes. For this purpose, the real-time online class lesson plans of 12 pre-service science teachers, who had experienced education utilizing online teaching tools for a semester, were collected and analyzed. The pre-service science teachers considered all the elements that were essential in traditional face-to-face class designs, including prerequisites, statements of learning objectives, stimulating motivation, teaching and learning methods, wrapping up, teacher-student interaction, and assessment. They devised teaching strategies that could overcome the limitations of online teaching and were not feasible in face-to-face classes for each element. Additionally, they were considering new instructional strategies tailored to the online teaching environment, such as creating a conducive environment for using online teaching tools and strategies related to checking the online teaching environment. However, for statements of learning objectives, stimulating motivation, and wrapping up, most of the pre-service science teachers predominantly utilized teaching strategies from traditional face-to-face classes, especially those involving the presentation of visual materials through online tools. Student-centered approaches were rarely implemented in stimulating motivation or wrapping up. These findings imply that one semester of exposure to the utilization of online teaching tools may be insufficient in teacher education. Thus, there is a need for a continuous and expanded educational program on the utilization of online teaching tools as part of pre-service teacher education.

The purpose of this study was to investigate the elementary school teachers' perception of science writing. In this study, 10 elementary school teachers who have taught in the 3rd or 4th grade science lesson in 2010 were selected. Researchers constructed interview guide in three parts including the teachers' understanding of science writing, the status of science writing teaching and the difficulties of science writing in their classes. For the investigation, semi-structured in-depth interviews with 10 elementary school teachers were conducted individually. The results showed that the elementary school teachers were unfamiliar with the word ‘science writing’ and considered science writing as a writing using science learning contents. Also, they think that teaching science writing in their science lessons was not needed and didn't assess and provide detailed feedback with the students' written works. Most teachers needed teaching materials and assessment tools for science writing. To develop elementary teachers' understanding of the value and use of writing for learning in science, they will need to participate in science writing programs for in-service teachers and various teaching materials and assessment tools should also be developed.
For this case study of gifted education, two classrooms in two locations, show life in general of the gifted educational system. And for this case study the identity of teachers and the gifted, help to activate the mathematically gifted education for these research questions, which are as followed: Firstly, how is the gifted education classroom life? Secondly, what kind of identity do the teachers and gifted students bring to mathematics, mathematics teaching and mathematics learning? Being selected in the gifted children's education center solves the research problem of characteristic and approach. Backed by the condition and the permission possibility, 2 selected classes and 2 people, which are coming and going. Gifted education classroom life, the identity of teachers and gifted students in mathematics and mathematics teaching and mathematic learning. It will be for 3 months, with various recordings and vocal instruction between teacher and students. Collected observations and interviews will be analyzed over the course of instruction. The results analyzed include, social participation, structure, and the formation of the gifted education classroom life. The organization of classes were analyzed by the classes conscious levels to collect and retain data. The classes verification levels depended on the program's first class incentive, teaching and learning levels and understanding of gifted math. A performance assessment will be applied after the final lesson and a consultation with parents and students after the final class. The six kinds of social participation structure come out of the type of the most important roles in gifted education accounts, for these types of group discussions and interactions, students must have an interaction or individual activity that students can use, such as a work product through the real materials, which release teachers and other students for that type of questions to evaluate. In order for the development of meaningful mathematical concepts to formulate, mathematical principles require problem solving among all students, which will appear in the resolution or it will be impossible to map the meaning of the instruction from which it was formed. These results show the analysis of the mathematics, mathematics teaching, mathematics learning and about the identity of the teachers and gifted. Gifted education teachers are defined by gifted math, which is more difficult and requires more differentiated learning, suitable for gifted students. Gifted was defined when higher level math was created and challenged students to deeper thinking. Gifted students think that gifted math is creative learning and they are forward or passive to one-way according to the education atmosphere.

The purpose of the study is to conceptualize SSI-PCK by identifying major components and sub-components to promote science teachers' confidence and knowledge on teaching SSIs. To achieve this, I conducted extensive literature reviews on teachers' perceptions on SSI, case studies of teachers addressing SSIs, SSI instructional strategies, etc. as well as PCK. Results indicate that SSI-PCK include six major components: 1) Orientation for Teaching SSI (OTS), 2) Knowledge of Instructional Strategies for Teaching SSI (KIS), 3) Knowledge of Curriculum (KC), 4) Knowledge of Students' SSI Learning (KSL), 5) Knowledge of Assessment in SSI Learning (KAS), and 6) Knowledge of Learning Contexts (KLC). OTS refers to teachers' instructional goals and intentions for teaching SSIs. Teachers often present a) activity-driven, b) knowledge and higher order thinking skills, c) application of science in everyday life, d) nature of science and technology, e) citizenship and f) activism orientations for teaching SSIs. KIS indicates teachers' instructional knowledge required for effectively designing and implementing SSI lessons. It includes a) SSI lesson design, b) utilizing progressive instructional strategies, and c) constructing collaborative classroom cultures. KC refers to teachers' knowledge on a) connection to science curriculum (horizontal/vertical) and b) connection to other subject matters. KSL refers to teachers' knowledge on a) learner experiences in SSI learning, b) difficulties in SSI learning, and c) SSI reasoning patterns. KAS indicates teachers' knowledge on a) dimensions of SSI learning to assess, and b) methods of assessing SSI learning. Finally, KLC refers to teachers' knowledge on the cultures of a) classrooms, b) schools, and c) community and society where they are located when teaching SSIs.
