The purpose of this study is to investigate the teaching-learning effects in the experimental classes for the 'Redox' unit of science textbook of 11th grade using self-regulated learning strategy. Simultaneously, the effects of teaching-learning through the student's characteristics of the scientific high school were also included. The experimental and the controlled groups were selected by the teaching-learning method established on self-regulated learning strategy and regular laboratory activity based on the teacher' instruction, respectively. The questionaries of the scientific inquiry and scientific attitude were examined by the student. For their achievement, the total score which was obtained from the formative evaluation and performance assessment was utilized. After the laboratory activity for the unit grounded on the self-regulated learning strategy, the mean values of the scientific inquiry, scientific attitude, and achievement by the experimental group were higher than those of the controlled group. There was significant difference between the two groups in the post-test. By the results of the post-test for the experimental group, there has been somewhat relationship between the self-regulated learning strategy and the scientific inquiry, the scientific attitude, and the scientific achievement.

The purpose of the study is to analyse students' academic achievement by their university major field and changes of grade. The subject was entering students of C medical graduate school in 2008. We divided entering students' major fields into two fields that are natural science and non-natural science filed. We analysed academic achievements of entering students by grades, curriculum from 2008 to 2011. And We analysed to find out whether there are differences in academic achievements by grades, curriculum of each major fields. There were no significant statistical differences in academic achievements by grade, curriculum of the two different university major fields. Futhermore, as a results of analysis on level(high, medium, low) distribution and differences of academic achievements by grade, curriculum of the two different university major fields, there were no statistically meaningful results. There is the need to keep entrance selection systems that open the possibility of selecting the students with other academic background. And there is the need to change general awareness assuming that there are differences in academic achievements by university major fields. We need to guide students with belief of their learning possibility.

2015 개정 교육과정에서는 미래 사회의 인재를 육성하기 위해 중학교에 정보 교과를 필수화하였다. 이를 지도할 정보·컴퓨터 교사를 확보하기 위해 비 정보과 교사를 대상으로 부전공연수를 실시하여 정보 교육을 할 수 있는 자격을 부여하고 있다. 이들은 일반 학습자와 다르게 교육학적 지식과 역량은 높으나, 내용 지식은 컴퓨터과학의 초보자 수준이다. 이러한 학습자의 특성을 고려하여 마이크로비트를 활용한 연수를 12차시 동안 진행하였고, 이는 비 정보과 교사의 프로그래밍 자아효능감에 긍정적인 영향을 준다는 것을 확인할 수 있었다. 그러나 본 연구는 단일집단에게 실험을 실시하였으므로 그 효과를 일반화하는 데 한계가 있다. 따라서 후속 연구에서는 비교 집단을 설정하는 실험 설계로 교육 효과를 검증할 필요가 있다.

This study developed examination test tools for concepts of weather changes of middle school students, analyzed the hierarchy of concepts associated with weather changes by means of knowledge state analysis method, and examined the knowledge state and lesson effects of each individual learner. The hierarchy of the knowledge state of concepts of middle school students associated with weather changes followed the steps of 'humidity ${\rightarrow}$ air mass ${\rightarrow}$ cloud ${\rightarrow}$ precipitation ${\rightarrow}$ front ${\rightarrow}$ weather'. Cases were identified where the knowledge state of students that was thought to be similar to each other among the group of students who have scored almost the same points and thus were thought to have almost the same learning ability, have turned out different in the knowledge state from each other. Namely, the level of knowledge state structuralized differed, suggesting that differing prescriptions should be made according to the knowledge state of each student concerned. Analysis of the knowledge state of learners helps prepare learning prescriptions for each student and appraise prior learning. To examine effects of teaching-learning that has taken into consideration the hierarchy of knowledge state and concepts, lessons were conducted in comparison with the order in which syllabuses are presented in the textbooks, with the result that when knowledge state of learners have been taken into consideration, students made scores significantly higher (p < .05) than otherwise. This indicates that in introducing the unit of weather changes better teaching and learning can be achieved by reordering the contents of subject matters of the textbook by grasping the knowledge state of learners.

The present study was carried out to analyse the frequency(%) for five kinds of inquiry context elements for six kinds of the high school science textbooks in the 7th curriculum. All the elements was classified into three process achievement level such as the basic, supplementary and further level introduced firstly in the 7th curriculum. Five elements of the inquiry context categories appeared as pure scientific context(61.8%), everyday context(22.2%), natural environmental context(7.7%), techno-industrial context(5.9%), and social context(2.4%) in the basic, supplementary and further level. Social context wasn't appeared in the supplementary level. In five elements of inquiry context, total elements appeared 7,139(85.5%) kfrequencies in the basic level and 691(8.1%) frequencies in the further level. However total elements appeared 529(6.4%) frequencies in the supplementary level. The kinds and frequencies of the elements for the inquiry context suggested in the basic level were more than those in the supplementary and in the further level. The social context was not appeared in the supplementary level. However five inquiry context elements were all appeared in the basic and further level.

The purpose of this study was to review the studies related to concept learning forcusing on the meanings, kinds, and characteristics of concepts. Then the characteristics of the concepts were analyzed in the three positions: metaphysics, epistemology, and psychology. It was identified that the word 'concept' were confused with the other words such as conception, construct, idea, notion, identity. It was also found that researchers defined the concepts by the use of various meanings. The instructional strategies for scientific concepts were also analyzed in this study. The study found that the instructional strategies for concept learning were developed according to the views about the nature of concepts. Described on the paper are three types of instructional models for science concepts suggested by constructivists as follows: concept formation, concept differentiation, and exchange. They developed the models based on the current research on the misconceptions of major scientific concepts.

In response to epoch-making development in science and technology, the innovative curricular materials have been begun to develop since the late 1950s and early 1960s. However, the new inquiry-centered materials have failed to be successfully used in teaching/learning practices of science. Among the various reasons for the failure, the very nature of the inquiry approach has been identified as the most critical problem. Nevertheless, fostering inquiry faculties on the part of the students has been emphasized as one of the most important objectives of science instruction. Therefore this study was conducted for the purpose of developing a practical inquiry-oriented instructional method. In order to obtain this goal the nature of scientific inquiry was analyzed and the status quo of science education in which inquiry-oriented instructional strategies were applied was examined. The results of the study are described in this paper.
