Concept mapping is a device for representing the conceptual structure of a subject discipline in a two dimensional form which is analogous to a road map. In the teaching and learning of earth science, each concept depends on its relationships to many others for meaning. Using concept mapping in teaching helps teachers and students to be more aware of the key concepts and relationships among them. The purpose of this study is to investigate the effect of the use of concept mapping on science achievement and the scientific attitude in ocean units of earth science. The results of this study are as follows; first, the science achievement of a group of concept mapping teaching is significantly higher than that of the group of traditional teaching. Also, when the achievement levels are compared among different cognitive ability groups, the effect is more significant in mid or lower level student groups than in high level groups. The use of concept mapping is more effective when the concepts have a distinct concept hierarchy. Second, the scores of the test of ‘attitude toward scientific inquiry’ and ‘application of scientific attitude’ of the group of concept mapping teaching are significantly higher than those of the group of traditional teaching, whereas the scores of the test of ‘interest in science learning’ of concept mapping teaching is not different from those of group of traditional teaching. Third, the survey on the use of concept mapping shows a positive response across the tested groups. The use of concept mapping is more beneficial in fostering the comprehension of the topic. A concept map of student's own construction facilitates the assessment of learning, thus promising the usefulness of concept mapping as a means of evaluation. In regard to retention aspect, concept mapping is considered to be more effective in confirming and remembering the topic, while less effective in the aspects of activity and interest. In conclusion, the use of concept maps makes learning an active meaningful process and improves student's academic achievement and scientific attitude. If the concept mapping is more effectively as an active teaching strategy, more meaningful learning will be attained.

The 2015 revised curriculum offers elementary students an unplugged computing education as a way to learn the concepts and principles of computer science in an easy and fun way and to improve their computational thinking. Yutnori is a traditional board game unique to Korea, which contains various contents such as history, culture, and science of our people, which helps to cultivate cultural identity of learners, and can effectively promote cooperation and communication among members. In this paper, we examined the possibility that Yutnori could be used as an unplugged computing tool in elementary school software education and convergence education. Korean traditional board game Yutnori has elements that can learn the sun and movements of heavenly bodies as well as sequential, selection, and repetitive algorithm elements. Unplugged activities that apply Korean traditional culture Yutnori is expected to help foster creative convergence talents by improving elementary school students' computational thinking, communication and community.

This study investigated the effect of cooperative learning on the middle school students’ conceptual change of atmospheric and water cycle and also examined the verbal interaction patterns in a cooperative group. The study also analyzed the relationship between the verbal interaction and students’ conceptual change in the cooperative learning situation. Two classes from a middle school were selected as an experimental group (cooperative learning group, n = 37) and a control group (traditional learning group, n = 37), respectively. The experimental group was taught by STAD cooperative learning model and received collaborative skill training. The results of the study can be summarized as follows: first, there were no significant differences in conceptual change between the two groups. As for the middle-achieving students on the pretest, however, the score of the cooperative learning group was significantly higher than that of the traditional learning group. Secondly, verbal interaction in the cooperative learning situation mainly happened among high- and middle achieving students. In addition, the students who were successful in undergoing conceptual change had more frequent verbal interactions than the students who were not. The study suggests that it is more important to interact between a teacher and students than to interact between the students and students in order to correct students’ misconception.

This study investigated the impact of student-centered instructions on students' academic achievement in science and on their attitudes toward science. Participants included 208 middle school students. The pre- and post-test control group design was employed. The control group was designed to have traditional instructions while experimental group 1 was applied both student-centered instructions and traditional instructions, and experimental group 2 was applied student-centered instructions only. The chaper of "Stimulus and Response" was selected for this study, and students were treated for 15 hours. Data were analysed using ANOVA. Results indicated that student-centered instruction had a significant effect on students' academic achievement(p<.01). The improvement of achievement through student-centered lesson is neither depending on genders nor previous academic achievement levels. Student-centered instruction also had a significant effect on students' attitudes toward science(p< .01). Only half of the class if a student-centered lessons and improve attitudes toward science could be. The improvement of the attitudes toward science through student-centered instruction is not depending on genders. But, student-centered instruction was more effective on the average student and the lower level students than the upper level students.

The purpose of this study was to quantitatively evaluate the effectiveness of learning management systems (LMS) in the physical geography class. The study adopted the experimental design and three classes participated in this study. The first class was controlled using only classroom lectures, the second class used PPT slides along with the classroom lectures, and the third class used online video clips along with the lectures. The experiments were conducted from the Spring Semester 2007 to the Spring Semester 2008 for the introductory physical geography course. The study results showed that online learning tools help students improve academic performance and their attitudes towards the class and the instructor. Compared to simple PowerPoint slides, voice recording attached to the visual lecture slide materials enhanced students' motivation. Class lectures with lecture slides did not improve students' scores. However, when the visual materials were combined with voice recording, the number of internet access to online class materials increased, and class attendance and students' final grades were improved. Based on the results, the instructional design model that combines classroom and online learning was suggested.

The purpose of this study is to investigate the effects of action learning on the satisfaction of majors by cultivating task-solving ability through self-reflection in the form of team learning for a certain period of time in the form of team learning by using action learning for students taking convergence curriculum in universities. The subjects of the study were 40 students from the Department of Sports Rehabilitation, a convergence of the Department of Sports and Health Management and the Department of Physical Therapy located in Jeollanam-do. This was conducted to confirm the difference in the effect of satisfaction. Comparison of changes in groups of experimental groups with action learning teaching methods showed significant differences in self-directed learning skills, problem-solving skills, and major satisfaction(p<.001)(p<.05). A significant difference in self-directed learning ability, problem-solving ability, and major satisfaction was also shown in the comparison of changes in control groups that applied traditional teaching methods(p<.05). Comparison of changes between groups showed significant differences in self-directed learning skills, problem-solving skills and major satisfaction(p<.05). Applying the action learning teaching method to the level of students in the convergence course will improve self-directed learning skills, problem-solving skills, and major satisfaction, and further research will be needed to expand the target and add variables to combine qualitative research.

본 논문에서는 사료 검증을 바탕으로 반차도의 문화원형(文和元型, Culture Archetype) 가상복원을 통한 3D 증강현실 콘텐츠를 개발하였다. 반차도란 의궤에 담긴, 조선 시대 왕실의 행차를 그린 그림을 의미한다. 조선의 왕실문화를 활용한 궁궐콘텐츠는 한국 고유의 것이며, 스토리텔링이 풍부한 반차도를 활용한다면 국민의 전통문화 향유를 증대시킬 수 있다. 현대에서는 재현행사를 통해 왕실의 행차를 재현하고 있지만, 실내에서는 재현하기 어려워 왕실 행차에 대한 문화유산 접근성이 낮다는 한계가 있다. 또한, 문화콘텐츠닷컴과 국립중앙박물관에서 제공하는 반차도 관련 멀티미디어 콘텐츠는 반차도 구성을 설명하는 것이 아니므로 심도 있는 반차도 학습에 어려움이 따른다. 이를 극복하고자 본 논문에서는 사료 고증 메타데이터에 기반을 두어 문화원형 가상복원 3D 증강현실 콘텐츠를 제안하고자 한다. 이를 토대로 문화원형 가상복원을 위한 3D 증강현실 콘텐츠의 활용 가능 모습을 살펴보고, 기록유산 반차도의 문화원형 가상복원기반 증강현실 3D 콘텐츠를 제안하다.

Piaget는 인류가 지식을 구성해 온 방식과 유사한 방식으로 어린이들도 자신들이 학습해야 할 지식을 학습할 수 있다고 가정한다. Kamii는 이 가정을 확인하고자 하는 열망으로 실험교수법을 이용한 수학수업을 실시하였다. 본 고에서는 Kamii가 얻은 결과 중 곱셈에 대한 결과를 발생론적 인식론 입장에서 논의가 이루어 질 것이다. 이 논의는 어린이들이 구성해 가는 지식이 선대인들이 사용하던 지식과 유사하다는 점과 어린이들이 구성해 가는 지식이 완성된 지식의 형태를 갖출 수 있다는 점을 중심으로 이루어진다. 또한, 그 결과로부터 전통적인 수학 교수법에 변화가 있어야 함을 발생론적 인식론을 적용한 수학 수업의 특징과 비교하면서 시사점을 논의하고자 한다.
