Problem Based learning(PBL) is a teaching and learning method to increase mathematical ability and help achieving mathematical concepts and principles through problem solving using the learner's mathematical prerequisite knowledge. In addition, the recent instructional situations or environments have focused on the learner's self construction of his learning and its process. In spite of such a quite attention, it is not easy to apply and execute PBL program actually in class. Especially, there are some difficulties in actually applying and practicing PBL in the areas of mathematics education in not only secondary school but also in college. Its reason is that in order to conduct PBL instruction constantly in real or experimental class there is no more concrete and detailed instructional content during the consistent and long period. However, to whom is related to mathematics education including instructors called scaffolders, investigation and recognition on the degree of the learner's acquisition of mathematical thinking skills and strategies is an very important work. By the reason, in this study, the instructional content was to be explored and developed to be conducted during 15 weeks in one semester, which was based on Problem Based Learning environment by the subject of the theories relevant to mathematics education in the college of education.

The curriculum especially in Korea plays a crucial role in developing instructional materials. It serves as a criterion for selecting and organizing content of teaching materials. Therefore, the validity of a curriculum can be justified through testing effectiveness of an instructional material developed in accordance with the curriculum. This paper presents an instructional method and material developed based on the current tendency of educational thoughts that emphasize STS and students - centered teaching strategies in science education. The instructional material was organized around the concept and its subconcept of "nutrition" as presented in the high school biology textbooks now in use in the nation as well as in a few world-wide countries. It was also organized by the use of biological events and phenomena which high school students in rural areas can easily encounter through their everyday lives. The significant findings in this study are : ${\circ}$ The achievement levels in experimental groups were higher than one in controlled groups. ${\circ}$ The students as well as the teachers involved in this study showed positive attitude toward the instructional method developed in the process of this study. ${\circ}$ The greater part of the students among the controlled groups hoped that biology would be taught by this kind of teaching procedure and materials.

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.

Recently, ICT has emerged as an indispensable tool for teaching a variety of subjects in education systems. In this paper, we examine the effect of the instructional models for ICT on the practical ability in the application of information with relation to the levels of self-regulated learning strategies. Students were divided into 3 groups, according to the instructional model for ICT which were problem search learning, problem solution learning, and discussion learning. As an experimental tools, we did pretest using self-regulated learning strategies measurement questionnaire and did pretest and posttest using practical ability in the application of information measurement questionnaire. The results show that higher level of self-regulated teaming strategies group has high practical ability in the application of information than lower level group. Other interesting results are also provided.

Despite the significance of functional thinking at the elementary school level there has been lack of research on teachers who play a major role in making students be engaged in functional thinking. This study surveyed 119 elementary school teachers to investigate their knowledge of functional thinking for teaching. A written assessment for this study was developed with a focus on the knowledge of mathematical tasks and instructional strategies to teach functional thinking. The results of this study showed that many teachers were able to design tasks corresponding to both the additive relationship and the multiplicative relationship, and to justify some strategies to promote functional thinking. However, some teachers had lack of understanding with regard to the core ideas of functional thinking. Based on these results this study is expected to suggest implications on what aspects of knowledge are further needed for elementary school teachers to promote students' functional thinking.

The purpose of this study is to investigate the effects of instructional strategies using the process of procedural thinking in elementary science classes on students' computational thinking and creative problem solving ability. For this purpose, instructional strategies using the process of procedural thinking for science class were developed and applied. The objects of this study were 6th graders from an experimental class (29 students) and a comparative class (29 students) at S elementary school in Gimpo City. The results of the study are as follows: First, as a result of examining the difference in the computational thinking ability between experimental group and comparative group, the experimental group scored higher than the comparative group, but there was no statistically significant difference. Second, the creative problem solving ability of the experimental group after applying this program was higher, and statistically significant differences were observed (p < .05).

The purpose of this study was to analyze the quality of 67 kinds of e-learning contents in an attempt to boost the effectiveness of distance teacher training. As a result of analyzing, the e-learning contents were rated highest in terms of 'training content,' followed by 'instructional design,' 'teaching & learning strategies,' 'evaluation' and 'interaction.' The scores of 'teaching & learning strategies,' 'evaluation' and 'interaction' were below 80 that was the standard of quality certification. In mean comparison(ES) of contents quality level between certified contents and non certified contents, 'instructional design' had the largest ES(effect size), followed by 'teaching & learning strategies,' 'evaluation'. In the analysis of evaluation factors, most of factors had a large effect such as 'webpage layout', 'selection of instructional design'. The findings of the study are expected to suggest what improvements should be made in the development of e-learning contents for distance teacher training.

This study analyzed the evaluations of instructors and experts on flipped learning-based engineering in order to suggest improvement strategies. This study was conducted with 8 engineering courses which participated in the flipped learning course development project of C university from 2017-2018. As a result of the analysis, the instructors and experts pointed out that the pre-learning was not performed and checked effectively. In this regard, the instructors suggested the students' burden of pre-learning, the lack of understanding about flipped learning, and the experts suggested the lack of instructional strategies to facilitate pre-learning. In addition, the instructors and the experts pointed out that the courses were still instructor-centered. The instructors evaluated that they operated the instructor-led course by themselves. In addition, the experts suggested that there was not enough instructional strategies to activate the learner-centered activities. The number of the students and the lecture room environment that were not appropriate for the learner- centered class were the evaluation opinions of both the instructors and the experts. In addition, the professor suggested the lack of understanding and preparation of the flipped learning of the instructors and the learner as the main opinion, and the experts pointed out that the online learning system and classroom was not linked for pre-learning, classroom learning, and the post-learning. Based on these results, suggestions for improvement of flip learning based engineering course were suggested.

Several studies have attempted to test students' misconceptions of physics and to provide teaching strategies in order to repair them. The results from these studies have revealed that the diagnosis of students' misconception is crucial, although they often failed to grasp the practice of its implementation. In terms of being a type of methodology for science education, the Internet allows large-scale surveys and investigations to be carried out in a relatively short period of time. This paper reports the results of the development, implementation, and evaluation of a WEb-based SYStem for TEsting students' Misconceptions in physics (WEBSYSTEM) aimed at three groups (science educational researchers who study students' physics conceptions using the system as a detector, school science teachers who practice it as an instructional material, and students who benefit from it for their self-directed learning). The web-based testing system is based on a review of the instructional development strategies of ADDIE (Gustafson, Branch, 2002; Rha, Chung, 2001). Results showed that WEBSYSTEM could work effectively as a multi-purposed tool for the three target groups with a further partial revision, providing educational researchers with resourceful data to study students' misconceptions in physics. Issues of administrative strategies, reexamination of questionnaires, and international collaboration via WEBSYSTEM are discussed.
