The effects of education utilizing history of science on science achievement and attitudes of the ninth grade students were investigated according to their achievement level, along with the development of teaching and ;earning materials. A total of 144 ninth grade students were divided into the experiment and control group. Instructing students using history of science was performed in the experiment group, while conventional instruction was used in the control group. The scores of both pre-test and post-test were estimated by ANCOVA. Instructions applying history of science were more effective in increasing the students' science achievement and attitude than conventional instructions. In particular, the former enhanced the achievements of the upper-level students, more than it did for the middle and lower-level students. In addition, using history of science showed a better effect on higher and middle-level students, in improving their attitudes toward science, than it did for lower-level students. This study suggests that the instruction utilizing history of science should be designed based on the students' achievement level, and that various teaching and learning materials related to the instruction were helpful.

In this paper, we developed an augmented reality learning tool suitable for chemical bond learning and proposed a process-oriented guided inquiry learning using mobile augmented reality (POGIL-MAR) to find out how it affects science achievement, science learning motivation and learning flow. Participants were 139 10^th-grade students from a coeducational high school in Gyeonggi-do, and they were randomly assigned to the control group (TL), the treatment group 1 (POGIL), and the treatment group 2 (POGIL-MAR). They learned the concept of the chemical bond from the Integrated Science subject for four class periods. Results of two-way ANCOVA revealed that the POGIL-MAR group scored significantly higher than the other groups in a science achievement test, science learning motivation test, and learning flow test, regardless of their prior science achievement. In addition, in the case of the low-level group, the POGIL-MAR group showed a statistically significant improvement in achievement compared to the TL and POGIL groups. The MANCOVA analysis for sub-factors of science learning motivation show that the POGIL-MAR group had significantly higher scores in intrinsic motivation, career motivation, self-determination, self-efficacy, and grade motivation. In particular, the interaction effect between the teaching and learning method and the level of prior achievement was significant in the intrinsic motivation. Meanwhile, the MANCOVA analysis for sub-factors of learning flow show that the POGIL-MAR group had significantly higher scores in clear goals, unambiguous feedback, action-awareness merging, sense of control, and autotelic experience. Based on the results, educational implications for effective teaching and learning strategy using mobile augmented reality are discussed.

This study examined 39 elementary teachers' perceptions on the frontier science teaching and their teaching efficacy. The results showed: elementary teachers were interested in and were well aware of the importance of the frontier science in human life and in this society. They also agreed with the necessity of teaching frontier science in elementary school. They, however, had perceptions that frontier science may not be appropriate for the level of elementary students. Moreover, the poor educational environment may act as constraints for frontier science teaching. The change of elementary teachers' teaching efficacy(t=-13.67, p<.01) was statistically significant after their participation of developing STEAM program on frontier science and practicing its lessons.

The purposes of this study is to identify the professional knowledge of the three elementary teachers for science-gifted students in teaching method. All teachers have received in-service program in gifted education, and have been recommended by their colleagues. Two teachers have instructed the gifted for more than five years, one teacher have instructed the gifted for one year and the general students for eleven years. For for this study, each teacher's lesson plans were collected, videotapes were recorded during lessons, and in-depth interview for each participant were conducted. All recoded data were transcribed and analyzed. Some unique characteristics of teaching method for the gifted were identified from the class instruction of participants. They had knowledge of teaching model for the gifted, especially Renzulli's three pod enrichment model. And they mainly used the materials developed by KEDI for the gifted. Also they had capability to be able to reconstruct them, but their lesson plans did not be realized well in their class. Some implications from findings of this study were suggested, such as teaching methods to improve the quality in the classes of the gifted in science.

The purpose of this study was to find out the learning effect of applying problem-based learning in esthetic major education at universities and to provide basic data for developing teaching and learning methods that can strengthen competitiveness in esthetic education. Therefore, this study conducted an empirical educational effect analysis by applying PBL classes to 15 students taking oriental therapy, a esthetic major course opened at H University. As a result, the average value of learners' problem-solving ability and cooperative self-efficacy increased after participating in PBL classes, and the effectiveness of PBL teaching and learning methods was confirmed, suggesting effective teaching and learning methods to increase learners' problem-solving ability and cooperative self-efficacy in the field of esthetic.

고등학교 1학년 공통과학(융합과학) 중 천문 분야의 교수 학습 지원을 위한 스마트교육 콘텐츠 자료실을 개발하였다. 공통과학과 관련한 현장 연구의 결과들은 개념 전달의 어려움과 함께 과학적 사고를 위한 탐구활동이 절대적으로 부족함을 제시하고 있다. 이에 교사들이 현장에서 활용할 수 있는 스마트교육 콘텐츠를 정리하고 이를 소개하여 학생들이 과학적인 탐구 활동을 통해 천문학 개념 이해에 도달 할 수 있도록 돕고자 하였다. 자료실 개발을 위해 공통과학 각 단원별 내용요소를 정리하고, 내용요소별로 관련된 스마트교육 콘텐츠를 수집한 후, 가장 적합하고 유용하다고 여겨지는 자료들만을 골라 이미지, 동영상, 시뮬레이터, 활동으로 분류하였다. 수집 및 분류한 스마트교육 콘텐츠들을 효율적이며 지속적으로 제공하기 위해서 온라인 자료실 형태의 사이트(astroedu.knue.ac.kr)로 개발하였다. 의견을 수렴하기 위해 현직 및 예비 교사들로부터 두 번의 공개 시연을 거쳐 수요자 중심으로 보완 작업을 실시하였다. 개발된 사이트는 교사와 학생들에게 필요한 스마트교육 콘텐츠를 찾아 제공하는 중간 공급자가 되어 교수 학습 지원의 역할을 할 수 있을 것으로 기대된다.

The purpose of this study is to understand how a teacher's teaching can be changed while he or she teaches the same contents in different classes. The qualitative research method was used in this study. Data were collected from classroom observations, several in-depth interviews, and stimulated-recall interviews after each class. All the data were transcribed and analyzed interpretively, and then, the results of the analysis were checked by each participating teacher. The results are as follows: First, changes appeared in each class in terms of the teaching items, tools, sequence, and time, even though the same teacher taught the same contents. It showed that the teacher's teaching practice changed immediately and intuitively in class. Second, teachers tried to implement "exploratory teaching" or "move-testing teaching" to address the emerging problems during their teaching. They then reflected on and modified their own teaching. This type of change, which happened during the teaching practice, can be an example of "Reflection-in-practice." Thus, the results of this study can provide helpful insights into how teachers might adapt and reflect in their teaching. It suggests that teachers need to recognize their subconscious teaching changes and learn "Reflection-in-practice."
