The purpose of this study is to develop a student-led instructional strategy that is central to the teaching-learning process and to investigate its effects. For this study, we analyzed the learner-centered learning types (discovery learning, problem-based learning, inquiry learning) and extracted elements applicable to newly developed teaching-learning. Based on this, a student-led class strategy was established using pre-learning, teacher collaboration, small group composition, and limited open data and product presentation, and then science classes were conducted. As a result of the post-tests of the five science core competencies of the experimental group using the student-led instructional strategy and the comparative group conducting lecture-based classes, the experimental group showed higher scores than the comparative group in the scientific thinking, scientific communication, and scientific attitudes (p<.05). Based on these results, it was confirmed that the student-led class, in which the student self-adjusts the entire process of designing, exploring, and presenting learning, can help the student's scientific ability. In addition, I would like to discuss the implications of teachers' teaching-learning composition.

본 연구에서는 중학교 1학년 과학 과목에서 교사와 학생의 언어적 상호작용을 강화한 수업 전략을 개발하고 실시하여 이 수업 전략이 학생들의 과학 개념 이해, 논리적 사고력, 과학 관련 태도에 미치는 효과를 알아보고자 하였다. 이를 위해 경기도 소재의 남녀공학 중학교 학생 200명을 선정하여 실험집단과 통제집단에 각각 100명씩을 임의로 배정하였다. 실험 집단에는 교사-학생 상호작용을 강화한 수업 전략을, 통제집단에는 교사 강의식 전통적 수업 전략을 적용하였다. 교사-학생 간 상호작용을 강화하기 위하여 의도적으로 단순 확인 질문이나 즉각적인 피드백보다는 사고 유발 질문과 지연 피드백을 사용하였다. 그 결과 상호작용을 강화한 수업 전략이 학생들의 논리적 사고력 향상에는 효과적인 것으로 나타났으나 과학 개념 이해와 과학 관련 태도의 향상에는 효과적이지 봇한 것으로 드러났다. 앞으로 이러한 수업 전략에 따른 다양한 수업지도안의 개발과 적용에 대한 심층적인 연구가 수행되어야 할 것으로 생각된다.

The purpose of this study was to develop instructional strategy for newspaper-based science writing and to examine the effect of its application. The target unit was 'change of weather' and 'a variety of gas' in the sixth grade of elementary school, and the teaching strategy was composed of 3 stages-writing including realistic, interpretative and comprehensive writing. The result of applying this strategy into actual classrooms was as follows. First, it was proven that the science writing strategy using newspaper articles actually helped improving science process skills of learners, in particular, integrated process skills. Second, this strategy for science writing changed the scientific attitude of learners positively. While they read the newspaper articles, their thinking became more elaborate and systemized, which seemed to serve to foster their openness, criticism, and perseverance. Third, the science writing strategy did not contribute to the improvement of learners' science study achievement. To improve the understanding of scientific concepts and principles of learners, it is needed that teaching program combines with argument-based activity organically. The above-mentioned findings show that this instructional strategy using newspaper articles can be applicable as one of effective methods in science writing.

This survey investigated elementary school teachers' Astronomical Spatial Concept and their Attitudes about Astronomy for Effectively Teaching Strategy. This study surveyed 53 teachers in Ulsan. The data were statistically analyzed by SPSS WIN 18.0. The results of this study are as follows : First, Elementary school teachers' level of understanding of the concept of astronomical space, usually lower. In particular, the lower the level of understanding of the concept of spatial location. Second, Elementary teachers' attitudes about astronomy, astronomers generally appreciate the value of the information and guidance, but difficult for astronomers had recognized. Third, the concept of space and astronomy astronomical elementary teacher attitudes about sex and there was no significant difference according to the teaching career. Therefore, in order to develop effective teaching strategies for elementary teachers attitudes about astronomy and astronomical space concepts from their spatial position to increase the understanding of astronomy, often on the job training to strengthen the astronomers should eliminate the difficulties.

This research defined professionality of science teacher from the perspective of PCK. An teaching strategy in the in-service teacher training for the gifted education was proposed based on the definition and implemented at an in-service teacher training program for the gifted education in order to explore about the teaching strategy and suggest practical implications that could improve the program. The in-service teacher training teaching strategy proposed in this research consists of three components: 'crafting activity materials', 'conducting inquiry-based experiment', 'developing rubric for identification of giftedness'. The survey carried out for the participants of the teacher training program showed that teachers perceived the importance of the need for the rubric for gifted identification, developing activity materials for the gifted education in science, and developing the rubric of gifted identification as properties for in-service teacher training programs fur the gifted education. However, the insufficiency of time and opportunities for being fully engaged in such a program made teachers feel lack of self-confidence in developing activity materials for the gifted education in science and rubric for gifted identification. Therefore, teacher training programs reflecting real features of the gifted education should be constantly developed and provided to enhance the effectiveness of in-service teacher training programs.

The purpose of this study was to investigate the effectiveness of teaching strategies for scientific conceptions in the units of oxygen and combustion in elementary school science textbook. 70 elementary school 6th grade students in Seoul participated. They were divided into experimental group and controlled group. Five scientific concepts were adopted from the units of oxygen and combustion in the 6th grade science textbook. Subjects' preconceptions were investigated by pre-questionnaires. A series of 6 instructional sessions based on the teaching strategy of cognitive confliction theory were given to the experimental group. By the end of the instructional session, a post-test was administered to both experimental and controlled groups. There was a statistically significant difference between post-test gains of the experimental and controlled groups. These results support the notion that the teaching strategy was effective for changing from preconceptions to scientific concerts.

The current study investigates how student-teacher interaction can be developed through task-based teaching in undergraduate students' Saudi teaching and learning context. An experiment was conducted for five weeks on 85 male undergraduate students at a Saudi public university based in Jeddah, Saudi Arabia. The study investigated different types of student-teacher interaction through task-based teaching (speaking activities). The results revealed that the experimental group (43 students) evinced much more enthusiasm, willingness, engagement and readiness in their inclass participation than their peers in the control group (42 students). The student-teacher interaction also helped students to be more responsive to general and specific topics in speaking activities. The study recommends that decision-makers in education make student-teacher interaction part of the student's monthly assessment. It also recommends that more efforts be made to foster the awareness of students, teachers, and parents awareness of the academic and non-academic importance of interaction. One final recommendation of the research is that student-teacher interaction should be more emphasized and integrated into the school curriculum and adopted as a critical teaching strategy.
