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.

The purpose of this study is to collect and analyze the student's pre-inquire and to obtain information on how to use the teaching-learning process. The specific research problem is to confirm the level of the student's pre-inquire, to identify the characteristics of each type, and to check what pre-inquire can be used in the teaching-learning process. The research was conducted on 149 children in the $3^{rd}$ and $4^{th}$ grade of elementary school, and collected a total of 2,034 inquires. As a result of analyzing three times, the students' pre-inquires accounted for 90% of Level 2 and Level 3, which are the inquires that give meaningful answers in the teaching-learning process. These results show that the pre-inquires presented before the students take up the new lesson are not low-level inquires and they can present meaningful inquires that can be used for teaching-learning. Next, as a result of analyzing the student's inquire by type, the factual question was the largest with 50%, followed by comprehension question, procedural question, application question, and prediction question. The factual and procedural questions showed that they could be used as learning activities during the teaching-learning process. Comprehension questions included in the wonderment question can be used as a learning question. And the application question is a question that can be applied to deepening activities, and the prediction question can be used in the inquiry and experiment process of learning activities.

This study aims to investigate science teaching and learning for the gifted in comparison with regular classrooms in elementary schools. A questionnaire was developed to survey gifted and general students＇ perceptions to elementary science teaching and teaming with employing a teaching and learning model for the gifted by Maker and Neilson (1995, 1996). The 28 item questionnaire consisted of four categories of content, teaching and teaming process, student product, and learning environment, and each category included six to nine items. Randomly selected 114 students from gifted classes and 99 students for regular classes responded to the questionnaire through the use of five-point Likert scale. It was found that there are significant differences between gifted and regular classes of science at all four categories of the teaching and learning model for the gifted. Therefore, science teaching and teaming for the gifted seemed to be differentiated from regular classes and emphasized students＇ creativity. However, no differences were appeared in a few items: study of gifted people and research methods (gifted=3.0; regular=.21 F=2.54), students＇ freedom of choice for topics of lessons, tasks, etc., (gifted=3.1; regular=3.0, F=0.31), student product addressed to real audience (gifted=2.8, regular=2.6, F=0.96), and students＇ high mobility to seek for data in library, etc. during class periods (gifted=2.3, regular= 2.3, F=0.01). It was concluded that science education for the gifted in Korea calls for quality improvement in terms of teaching and teaming in various aspects.

The purpose of this study was to examine the consistency and balance of learning objectives of units and instructional units according to grades and educational domains. Educational domains were cognitive(scientific knowledge), scientific inquiry(inquiry process skills), affective(scientific attitude), and science-technology-society(STS). Learning objectives of life field of the 7th elementary science curricular teaching guidebooks were analysed. Scientific inquiry process skill objectives(43.5%) were most dominant in units, but cognitive objectives(53.9%) were most dominant in instructional units. STS objectives were most recessive in both units and instructional units. Especially, objectives of units and instructional units were shown no consistency by grade. The results of this study suggested that the textbooks and teaching guidebooks should be developed consistently by considering learning activities and contents on the basis of background and properties of science curriculum.

The purpose of this study is to analyze lesson plans from third to sixth grades of science and to find out teaching strategies in respects of learning functions provided by preservice elementary teachers in education university. On the whole, to control students' learning process preservice teachers used more shared-regulation strategy than strong teacher-regulation one. Teaching activities for regulative learning function were most used in strategy of strong teacher-regulation, and in strategy of shared-regulation those for cognitive learning functions were most used. But teaching activities for affective learning functions were used a little considered in both teaching strategies. In introduction step of instruction, affective and regulative learning functions were more instructed by strong teacher-regulation strategy and cognitive learning functions were more instructed by shared-regulation strategy. The affective, cognitive, and regulative learning functions were largely planned by shared-regulation teaching strategy in development. The regulative learning functions were planned by strong teacher-regulation strategy than by shared-regulation strategy and affective learning functions were considered a little bit in consolidation. There was a tendency that strong teacherregulation strategy was increased in lessons for fifth and sixth grade.

The science writing is recognized for useful learning method to boost up scientific thinking for all class course as well as traditional lecture and experiment. Many researches say that science writing is helpful to extend students' science knowledge and scientific attitude. By the way, the researchers thought that science writing can also improve the science process skill if students participate in delicately organized learning program. In this study, we had contrived the teaching & learning strategy of science writing to improve science process skills. The learning program covers all field of Klopfer's process skills with various forms of writing; explaining writing, logical writing, critical writing, and creative writing. The learning program has been developed for 5th grade students in the regular classes in order to enhance science process skills as well as knowledge and scientific attitude. Not to miss any process skill or various kinds of writing, we used 3 dimensional frame. The axes of the frames are science process skills, forms of writing, and science curriculum contents. The students are given the final writing theme at the beginning of each chapter. They drill science process skills step by step during the classes, and have a chance to talk each other before the final writing. They practice writing skills from one sentence to full article by degrees. The effect of the program was examined by students' work and TSPS (Test of Science Process Skill). The result showed that 5th grade students had a meaningful progress in science process skills as well as knowledge and scientific attitude. we could confirm it with examining students' work in the class.
