The purpose of this study is to propose a teaching and learning model that can effectively manage convergence education, which is one of the concerns of university education, at the level of course. The pre-collaborative instructional design stage is to prepare the operation of the convergence project course. It shares the common goal and establishes a team of relevant professors to set up the actual convergence project topic and establishes cooperation relationships with industry or community as needed. In the convergence project activity, students will be able to understand the learning objectives, learning activities, evaluation methods, and explain the subject of the convergence project by proceeding with the whole orientation. Students organize teams of interest and conduct learning and design activities on convergence technologies and present their results. In the educational improvement activities, professors will share the lesson process and results and discuss improvements through the improvement seminar. As a result of analyzing the effectiveness of the proposed convergence project based teaching and learning model, the convergence project experience has improved the cooperative self - efficacy for the learners and the results were confirmed that students perceived to achieve the expected learning goal and satisfied with their experience.

The major objective of this study was to develop effective teaching methods for middle school science. To achieve the objective, general characteristics of science teaching methods were discussed and the 6th national science curriculum was analyzed in terms of epistemological backgrounds, cognitive demand and organizational characteristics. It was analyzed that epistemological background of the curriculum was based on the traditional philosophy of science. It was also indicated that modern Philosophy of science was only partially reflected the objectives of the past curricula. The cognitive demand of the curricula has also been higher than students' actual level of cognitive development. Based upon these results of the analysis, several exemplary instructional methods were developed.

Main objectives of the this study are: to develop a model of "Flipped Leaning" that is designed to enhance self-directed learning, learning motivation and self-control, and to verify its effectiveness-in higher education. The verification process initially concentrated on the feasibility study of the model with a thorough literature review and case analyses; then, its general and practical applicability were tested with a field study. As a result, first, the CHANGE Class Model, specifically designed for effective and efficient "Flipped Learning", was developed. It is thus named for the stages that the learning process takes place in the model-i.e., (1) Check ${\rightarrow}$ (2) Ask ${\rightarrow}$ (3) Notice ${\rightarrow}$ (4) Group presentation ${\rightarrow}$ (5) Evaluation, and it emphasizes the dynamic, questions centered (i.e. back and forth between the students and the instructor as well as between the students) learning process. Second, the Model was instrumental in enhancing self-directed learning, learning motivation and self-control; thus, as a result, it significantly improved the effectiveness, the level of concentration and the attractiveness of the learning process. The value of this study lies in pointing to a clear plan to allow a student in higher learning to set-up a self-directed learning plan, to be able to control it while being continuously motivated to complete it.

Secondary schools in Korea have been faced with several critical problems in their science education. Among them the most fundamental are the problems which involve the development and operation of science curricula. This study had, therefore, its objective to develop the suggestions for sabstantial science curricula of secondary schools. Actually the objectives are trifold as following specific description. ${\circ}$Analysis of the rationale and theory of science curricula. ${\circ}$Status survey of secondary science curricula and identification of the problems in development and operation of the curriculum in foreign and Korean secondary schools. ${\circ}$Development of suggestions for substantial science curriculam of secondary school. In order to attain these objectives the methods of literauare survey. questionaire and interview were used. Through these methods several problems are found and identified. The major findings and problems identified in this study are: ${\circ}$aims, goals, and objectives of science education are not dfferentiated. ${\circ}$the curricula show discipline-centered seleetion and organization of the content:neglect the relationship of science-technology-society and life-world context. ${\circ}$shortage of weekly instructional hours for science subjects. Other findings and problems are described and the descriptions of the suggestions for substantial curricula are followed at the end of this paper.

An analysis on the Inquiry unit of Science 10 textbooks was conducted in terms of nature of science (NOS). The subject of the analysis was instructional objectives, activities and sentences in the unit of ten Science 10 textbooks. Contents of the instructional objectives could be grouped into nature of science, nature of scientists, scientific methods, and Science-Technology-Society. The concrete nature of scientific knowledge (SK) and constructing scientific theory or model, however, were not found in the objectives. The total number of activities in the Inquiry unit was 38. Seventeen out of them were presented without any supplemental or introductory materials, and 21 activities were provided with information followed by questions, discussions or investigations. For the most activities, any clear statements about NOS elements and desired/informed views of NOS were not made. The sentences of the Inquiry units were mixed up with constructivist and inductive views on NOS. The definition of science tended to be described based on the inductive view. And the generation of SK tended to be described as discovering regularities in natural phenomena rather than constructing theories. For science teachers who want to teach NOS effectively, stating clear learning objectives and elements of NOS and presenting reading materials with relevant views on nature of science were necessary.

The purpose of this study is to find out whether Achievement Tests are fully performing their role as an objective standard that measures student's educational achievement level by analysing the content validity of Achievement Tests developed by KICE and teachers at elementary school. In the study, the content validity of achievement tests were analyzed in the behavioral content objective dimensions. 60 instructional objectives from the Unit one to the Unit six contained in the teachers' guidebook for the elementary third-grade Math subject were analyzed into dimensions of behavior and content. And the Achievement Test developed by KICE and teachers in five elementary schools randomly chosen were collected and analyzed. Then, differences of the proportion between instructional objectives and evaluative objectives in each dimension statistically were verified. The results of the study are as follows : 1. In the dimension of behavior, as analysing and comparing the content validity of achievement tests, there was no significant difference in all domains(knowledge, comprehension, application, analysis, synthesis and evaluation). (p<.05) Therefore, it could be concluded that content validity of the Achievement Test is very high. 2. In the dimension of content, similarly there is no significant difference in all domains between achievement tests by both KICE and teachers. (p<.05) Therefore, the content validity of all tests are very high. In conclusion, it could be concluded that content validity of achievement tests is considerably high in content and behavior dimension. The study suggest the followings : 1. By expanding to the other subjects, there are needs to analyze and verify the content validity of achievement tests. 2. Even the content validity of achievement tests is considerably high however, achievement items are focused on evaluation 3 domains(knowledge, comprehension, application). Therefore evaluation evenly among 6 cognitive domains is required. And further to reduce the deviation of schools, there are needs to active interchange between teachers.

The primary purpose of this study was to assess understanding of concrete and formal operational science content by concrete and formal operational students in secondary school physical science classes. To carry out this study subjects were selected from junior high schools of over 2500 students, and they were identified as concrete, transitional, or formal operational using GALT(Group Assessment of Logical Thinking) developed by Roadrangka, Yeany and Padilla(1983). Instructional objectives were extracted from the science content taught during the second term of the academic year in the 7th, 8th and 9th grade, and they were classified as concrete or formal operational. Written test involving those objectives were constructed and administered. The results of this study suggested that formal operational thought brought deeper understanding to concrete science content as well as formal science content. Differential effects by sex on understanding of both concrete and formal science content were contradictory through the grade levels. Results of multiple comparison tests suggested that students categorized as formal operational demonstrated no better understanding of concrete science content than those categorized as transitional. However, they demonstrated better understanding of formal science content.

Portfolio assessment provides many opportunities to foster children's creativity and to increase their responsibility for learning. few research study has been conducted in this area, and this assessment method has scarcely been administered in primary science class, Proper and effective use of portfolio assessment in our primary science class requires basic research on how to design and administer the method. Based on the earlier study on typical structures and components of portfolio assessment, the assessment instrument was developed on various primary science topics, The development team was consisted of one science education specialist and nine pre-service elementary school teachers. It takes ten months to develop instruments for 27 class hours. The development process was reciprocal in that development and revision cycle was repeated more than 7 times. The portfolio assessment instruments consist of instructional objectives, developers' evidence for the objectives, and assessment criteria. Adopting a new way of assessment into science class inevitably causes lots of confusions to teachers and children. The absence of basic research studies must be a critical barrier for successful administration of a new assessment method such as portfolio assessment. further research is required in the preparation and administration of portfolio assessment in our primary science classroom.
