In the information-oriented society, the paradigm of education has changed from the existing traditional teaching-centered education to the learning-centered education. In the Web-based Learning System which an learning-centered educational environment using the internet, students should have responsibility of their learning as taking more opportunities to participate their learning positively, to control their process of learning and to evaluate their learning by themselves to improve self-directed loaming ability. In this paper, the Web-based Learning System with a Self-Study Plan to lead students to select own purposes and methods of the study and write a self_evaluation is developed. The Self-Study Plan is a guide to lead the process, an order to have an individualized study and a report to evaluate own study. In addition, the suggested System is designed through object-oriented method using the extension mechanism of UML to archive the improvement of reuse and maintenance.

In this study, students' responses to anomalous data in studying ‘density' were analyzed, and the relationships among trait/state self-regulation strategies, the degree of cognitive conflict, and conceptual change were examined. A trait self-regulation strategy test, a preconception test, and a test of response to anomalous data were administered to 352 eighth graders. Among them, 146 students whose preconceptions were consistent with the presented initial theory were selected. After they had read a scientific explanation, a state self-regulation test and a researcher-made conception test were administerd. There were no significant correlations among the subcategory scores of trait/state self-regulation strategies and the degree of cognitive conflict. The scores of the conception test were significantly correlated with those of trait planning, trait effort, state planning, state self-monitoring, and state effort. State effort was only a significant predictor on students' conceptual change.

The purpose of this study is to develop and apply materials to teach about reflection of light by peer instruction. These which consist of both hands-on experiments and ConcepTests based on students' preconceptions found in previous researches are inducing active interaction between peers during instruction. Data from 29 university students were rate of correct answer of pre and post tests, results of conceptests before and after peer discussion, homework for strengthening their conceptual changes, and RTOP result for analysis of learners' perception about this method. Learners' preconceptions on reflection of light and position of image are changed effectively into scientific concepts. And they evaluate this teaching method helps conceptual understanding and interaction of an instructor and learners.

The purpose of this study was to analyze the conception type change and to investigate the effect of understanding on concepts in electrochemistry after general chemistry lessons. The significant differences in concept understanding of electrochemistry were shown in both groups. Statistically significant gains in both groups were as shown in distinguishing the chemical cell, in identifying the anode and cathode, and in understanding current formation and flow, while, significant achievements in understanding the role of the salt bridge, and the need for a standard half-cell were not found. Taking elective chemistry II in high school had an effect on understanding related concepts of electrochemistry in general chemistry lessons. It was shown that many freshmen had difficulties in understanding exact related concepts in several kinds after general chemistry lessons. In order to solve these problems, it is necessary to teach contents of the basic concepts in electrochemistry exactly and to hold supplementary lessons.

This study was a one group, pre-post test design experimental study to identify the effects of problem-based learning applied to adult nursing subjects on meta-cognition, problem solving, professional self-concept and self-directed learning of nursing students. The participants were 60 fourth grade students who had registered for adult nursing class from a nursing university in D metropolitan city, the data were collected from September to December, 2022. The adult nursing class model was designed based on the ADDIE model suitable for PBL. The class period was conducted for 15 weeks, with 8 weeks of lectures, 2 weeks of exams, and 5 weeks of Barrow and Myers 5-step PBL learning. The collected data were analyzed using the SPSS/WIN 20.0 Program, and paired t-test was used to test the differences between variables before and after the intervention. There was a statistically significant difference in metacognition(t=-8.04, p<.001), problem solving(t=-4.08, p<.001), professional self-concept(t=-4.67, p<.001) and self-directed learning(t=-4.69, p<.001) between pre and post problem based learning. Therefore, our result recommend that to apply problem-based learning in various major subjects to strengthen nursing students' metacognition, problem-solving, professional self-concept, and self-directed learning skills.

This study investigated the effects of assigning cognitive roles, a method that may promote verbal interaction in knowledge-building processes, in small-group discussion for science concept learning. Two classes (62 students) of 7th-graders respectively received a concept learning instruction through small-group discussion with assigned cognitive roles (CR) asking to explain and contradict one's idea and to synthesize and conciliate group's idea, and a concept learning instruction through small-group discussion with no specific assigned roles (NSR), for 9 class periods. After the instructions, the tests of achievement, conceptions, the perceptions on science learning environments, and the perceptions toward small-group discussion were administered. ANCOVA results revealed that low-achievers in the NSR group performed significantly better than those in the CR group. Similar tendency was also found in the scores of the conceptions test. Two groups did not differ significantly in the perceptions on science learning environments and toward small-group discussion.

One of the characteristics in math -abstract concept- makes the students find difficulties in understanding general ideas about math. This study is about how much do the modeling lessons using the technical instruments which is based on the realistic mathematical theory influence on understanding the mathematical concept. This study is based on one of the contents the first grade of middle school students study, the function, especially the meaning of it. Some brilliant students being the objects of this study, mathematically experimental modeling lesson was planned, conducted. Survey on the students' attitudes about math before and after the modeling classes and Questionnaire survey on the effectiveness about the modeling class were conducted and their attitudes were recorded also. This study tells that students show very meaningful changes before and after the modeling class and scientific knowledge seems to be very helpful for the students to understand the mathematical concept and solve the problems. When scientific research and development get together with mathematics, students will be more motivated and be able to form the right mathematical concept easily.

In this study, a concept learning strategy emphasizing social consensus during discussion (SCS) was developed. The instructional effects of this strategy were compared with those of cognitive conflict strategy (CCS) and traditional instruction in the aspects of students' achievement, conceptions, communication apprehension, perceptions of science learning environment, and perceptions of small group discussion. There were no significant differences in the scores of an achievement test. For the students of low communication competency, however, the scores of the CCS group were significantly higher than those of the traditional group. The adjusted mean of the SCS group was higher than those of the other groups in a conceptions test. The social consensus strategy was also found to be more effective in learning concept for those who were more competent in communicating. No significant differences were found in the communication apprehension. The scores of three groups did not differ significantly in the subcategories of 'personal relevance' and 'students' negotiation' of the test of the perceptions of science learning environment. However, the students in the SCS group scored higher in 'participation'. The students in the SCS group perceived small group discussions more positively.

도형의 합동은 도형의 대칭이나 도형그리기를 배우는 데에 기본이 되며, 도형의 성질을 이해하고 모양을 그리는 능력을 기르게 할 수 있다. 도형의 합동을 공부해야 일상 생활에서 필요로 하는 디자인이나 아름다운 예술 작품에 대한 소양을 가질 수 있다. 하지만 합동 학습을 할 때에 개념을 형성하는데 드는 시간보다 종이를 자르고 도형의 본을 뜨는 행동과 같은 구체적 조작 시간이 많이 소요되기 때문에 학생들 간의 상호작용은 물론 교사와 학생들과의 상호작용 시간도 기대하기 어렵다. 따라서 본 연구에서는 초등학교 학생들에게 학습효과를 높일 수 있도록 상호작용 이론을 합동학습에 적용하여 학습자들이 합동의 개념을 쉽게 이해할 수 있도록 하였고 동시에 동시적 비동시적 의사소통이 가능한 웹상에서 실시하는 합동학습 코스웨어를 개발하고 적용하였다.
