Two project-centered secondary school programs were studied as part of an effort to elucidate successful components for science reform-based curriculum development. The Teachers for Exciting Science (TES), and Foundational Approaches in Science Teaching (FAST) programs in Korea and U.S., respectively, are project-centered programs because their curricula are centered on the activities initiated and engaged in by the students. Students serve as principal investigators in their projects, and teachers serve as guides. Both programs were analyzed based on criteria such as curriculum design, teaching, lives of students, lives of teachers, evaluation of program, from the Third International Mathematics and Science Study (TIMSS). In the programs, teachers and students directed the development of curricula and their implementation. Students assumed teacher roles as mentors of other students. And emphasis was on development of communication skills through student-delivered talks and written papers, and professional development of teachers as educators and scientists. Participation in TES stimulated secondary school student interest in science, encouraged inquiry thinking, increased achievement in learning science, and promoted better awareness of science related to real life. FAST students practice laboratory and field techniques, experimental design, hypothesis formation, generalization, and practical implications of research as academic and applied disciplinarians. These project-centered programs have been successfully implemented in field, lab, and classroom curricula for secondary science education. Comparison of these programs will provide an opportunity for identifying key elements instrumental in successful implementation of guidelines for science education, as measured through successful outcomes.

Digital textbook project is one of government-driven project to improve education due to integrating technology. Digital textbook need to be universally designed to fit for each student. Recently, universal design for learning( UDL) gains great attention as one of promising approaches for the development of the digital textbook through giving various options and flexibility to all students. UDL has three main principles, first provide multiple means of representation, second provide multiple means of action and expression, third provide multiple means of engagement. The purpose of the study is to analyze fourth grade science textbook according to three UDL guidelines and suggest implications to improve an existing science textbook. The results indicated that fourth grade science digital textbook has been partly applied UDL guidelines like implementing multimedia and multi- mode contents, learning and communication tools, and motivation strategies. But options which students can choose according to their needs and styles are insufficient and tools for expression and communication need to enhance for helping each student to overcome his/her obstacles for learning and need to be more and elaborate to support learner-centered science digital textbook.

The purpose that the curriculum appropriate for the student's level pursues is to offer to a student the curriculum that can satisfy the student's interest, aptitude, and requirements. This curriculum has recently enforced all over the country, but the careful research and the plan for verification on its effect are required so that it may accomplish its purpose. This study, centered on the reading comprehension ability of Freshman English of the High School, aims to suggest a more desirable procedure for organizing and enforcing the curriculum appropriate for the students' level. In order to provide the best curriculum appropriate for the student's level. (1) the diagnosis of the individual student's level should be made first ; (2) the syllabus focused both on the grammar and on the communicative functions should be prepared ; (3) the teaching material on the basis of the syllabus should be selected considering the student's interest. and requirements. The new method of teaching-learning English should also be developed with the enforcement of the new curriculum discussed here. The curriculum appropriate for the student's level has many kinds of problems but these disadvantages should be overcome for providing the better educational system for the individual student.

The purpose of the present study is to investigate the effects of mathematical communication-centered teaching using peer feedbacks on students' mathematics achievement and mathematical dispositions toward mathematics, and then this study examined the characteristics of feedbacks used by students. To do this study, two sixth grade classes selected from an elementary school in Seoul participated in the current study; one class for a treatment group applying mathematical communication-centered teaching using peer feedback, and the other for a comparison group applying traditional teaching using teacher-centered communication. The results of this study showed the fact that a treatment group of mathematical communication-centered teaching applying peer feedback scored statistically higher than a comparison group applying teacher-centered communication with respect to both students' mathematical achievement and disposition. Especially, this communication-centered teaching program focused on peer feedback was more effective to middle or lower level students than higher level students. In addition, mathematical communication-centered teaching applying peer feedbacks helps students reflect their own thinking process about problem solving, and students experienced the improvement of their confidence about mathematics from opportunities to provide peers with feedbacks. Finally, the present study suggests the important role of communication in mathematics learning, particularly student-to-student feedbacks rather than teacher-to-students feedbacks. That is to say, students need to have many opportunities to represent their own mathematical thinking processes using mathematical language.

This study aimed to building models to understand the relationships between reasoning resources and content knowledge. We applied Support Vector Machine and linear models to the data including fifth graders' scores in the Cornel Critical Thinking Test and the Iowa Assessments, demographic information, and learning science approach (a student-centered approach to learning called the Science Writing Heuristic [SWH] or traditional). The SWH model showing the relationships between critical thinking domains and academic achievement at grade 5 was developed, and its validity was tested across different learning environments. We also evaluated the stability of the model by applying the SWH models to the data of the grade levels. The findings can help mathematics educators understand how critical thinking and achievement relate to each other. Furthermore, the findings suggested that reasoning in mathematics classrooms can promote performance on standardized tests.

This study focuses on the instructor's role in student-centered learning and aims to test the effects and moderating role of instructor feedback on perceived loafing in team project-based learning. A conditional effect model including team efficacy, perceived loafing, instructor feedback, and team performance was proposed. Data were collected from students who registered for team project-based learning courses at a university in South Korea. A total of 420 cases were subjected to moderated mediation analysis. The results demonstrated that instructor feedback was negatively related to perceived loafing and moderated the relationship between team efficacy and perceived loafing. Furthermore, instructor feedback moderated the relationship between perceived loafing and team performance. In particular, even when perceived loafing was high, students who received frequent instructor feedback were found to significantly reduce the damage to team performance. Based on these findings, the importance of instructors' facilitation in team project-based learning is discussed.

This study investigated the influences of the cooperative and the individualistic learning strategies on the academic achievement and the attitudes toward science instruction and science by the level of achievement. These two learning strategies endowed students with the responsibility of learning and emphasized student-centered learning which included higher order thinking activities. Cooperative learning group students studied the tasks through small group discussion, and individualistic learning group students solved the same ones individually. In the traditional group. teacher-centered expository lesson was used. The subjects of this study were 7th graders of coed middle school, and were taught about separation of mixture for 10 class periods. Two-way ANCOVA results revealed that the test scores of academic achievement for cooperative learning group were significantly higher than those of individualistic and traditional learning groups. The attitudes toward science instruction and science were also more positive in cooperative learning group than the others. No interactions between the treatment and the level of previous achievement indicated that the cooperative learning strategy was effective regardless of the level of achievement.

Purpose: The purpose of this study is to determine the effectiveness of cooperative learner-centered methods of sex education. Methods: This study was carried out on 5th grade elementary school students in D-district. Nine classes were divided into 3 groups using each different teaching methods: group A (a cooperative learning), group B (a lecture) and group C (a control group for a comparison). The study period was from Oct. 17 to Dec. 2 in 2011. Both groups A and B received sex education lessons for 40 minutes for 4 weeks and were tested their sex knowledge and attitude to compare the differences. Results: The scores of sex knowledge for all three groups were increased and their sex attitude was increased as well. The points of sex knowledge between pre and post test in group A are greater than the group B's. Thus, the cooperative learning approach with Group A was more effective to improve student's sex knowledge. But the difference between the sex attitude scores was not statistically significant. Group A and B showed a positive improvement in both their sex knowledge and attitudes compared with the control group. Conclusion: This experiment shows that an active teaching methods is more effective to improve student sex knowledge than a passive approach. Thus, a cooperative learning method results in increases of both student's sex knowledge and interests in learning sex education. It needs to develop more diverse teaching methods and programs on sex education that are more systematic and tailored.

Objectives : Recently, the interest on medical education in flipped learning has been growing. Competency-based curriculum is also required through changes in teaching methods within the Korean medicine education. In this study, flipped learning method was applied to 'medical ethics' class to examine the perception and experience of flipped learning from the Korean medical student's perspectives. Methods : The study was conducted on 15 preparatory course freshmen students who took the 'medical ethics' course, in the second semester of the year 2017 at 'A' University. The study was proceded in two steps; 1) fill-in the questionnaire twice (before and after the class), and 2) in-depth interview with semi-structured questionnaire. The $1^{st}$ questionnaire in the first step was consisted of 'Experience on flipped learning before the class', 'Which section of the flipped learning class do participants have expectation', 'Interest and expectation on flipped learning'. In the $2^{nd}$ questionnare, the participants were asked 'Which section of the flipped learning section that the learning effect was maximized', 'Association between 'flipped learning' method and 'Medical ethics' course' with 5-point Likert scale and frequency. Results : The results showed that flipped learning method works very effectively in the 'medical ethics' course (63.6%). After the flipped learning class, the participants showed positive change in a attitude of the class (72.7%). However, this teaching method might be inappropriate for participants who had difficulties in pre-learning or a passive attitude and lecture-centered instruction (LCI) classes. Conclusions : Though applying flipped learning method to the 'Medical Ethics' was effective, to make pre-learning better, the instructors should prepare countermeasures for passive participants, help interact well among the participants, and plan a lesson thoroughly for changing LCI classes to student-centerd instruction(SCI).

Fourteen Special high schools for developing talents in Science, Foreign Languages, and Arts in Seoul Metropolitan city were analyzed in terms of their educational objectives, Students screening system, curriculum, teaching-learning methods, teachers, and consistency with higher education. Special high schools in talent area were more or less similar to each other in all the above aspects. However, special high schools in different talent areas were quite different in student screening, teaching-learning methods, teachers, and consistency with higher education. Public schools were more affluent than the private ones. Special high schools in Science, arts and Sports were providing individualized, activity oriented, process-oriented teaching-learning methods, while the Foreign languages high schools excercised teacher-centered, grammar oriented, lecture-focused teaching methods more. Special high schools in arts and sports could have consistency with higher education because the university focuses on talents in the specified field rather than academic scores. In conclusion, the schools have a great deal of rooms to improve in teaching-learning methods with which students can maximize their potential development. However, the special high schools were equipped with better learning environments than regular high schools in many aspects.
