The purpose of this study was to develop a teaching strategy focused on science writing and to investigate its effects on enhancing students' problem solving ability. A teaching strategy using science writing enhancing problem solving ability (REWS model) was designed. The REWE model consisted of four stages: 1) Sensing and Stating of Scientific Problem by Reading (R stage), 2) Exploring Problem (E stage) 3) Explaining by Writing (W stage), 4) Integrated problem-solving (S stage). 135 10th grade of students were assigned to one experimental group and one control group. Students in the experiment group were taught by REWE model. Students in control group were taught by traditional lecture-based instructions. The program was implemented over a semester. The results indicated that the experimental group presented statistically meaningful improvement in critical thinking necessary to solve problems (p<.05). This study suggests that science writing can be effective for improvement of problem solving ability.

The purpose of this study was to examine the effects of physical activity using visual stimulation smart devices on the athletic performance and attention - The conclusion is as follows. The physical activity using visual stimulation smart device was applied to the infant. The pre - and post - experiment results showed that the infants of the experimental group were higher than those of the control group. Specifically, the ability of the infant to participate in physical activity using the visual stimulation smart device was improved by sit-up bending and centering ability. Also, physical activity using visual stimulation smart device helped to improve attention of infants. In other words, it was confirmed that information and communication technology (ICT) and physical activity affect both physical and cognitive development of infants. Therefore, in order to improve the athletic ability and concentration of children more effectively, it is possible to maximize the educational effect by teaching the contents using various contents that can motivate the infant rather than the same teaching method.

This study investigated three $10^{th}$ grade students' concept of rate of change while they perceived changing values of given functions. We have conducted a teaching experiment consisting of 6 teaching episodes on how the students understood and expressed changing values of functions on certain intervals in accordance with the concept of rate of change. The result showed that the students did use the same word of 'rate of change' in their analysis of functions, but their understanding and expression of the word varied, which turned out to have diverse perceptions with regard to average rate of change. To consider these differences as qualitatively different levels might need further research, but we expect that this research will serve as a foundational study for further research in students' learning 'differential calculus' from the perspective of rate of change.

In the field of arithmetic in mathematics education, there has been lack of fine-grained investigations addressing the relationship between students' construction of division knowledge with fractional quantities and their whole number division knowledge. This study, through the analysis of part of collected data from a year-long teaching experiment, presents a possible constructive itinerary as to how a student could modify her unit-segmenting scheme to deal with various fraction measurement division situations: 1) unit-segmenting scheme with a remainder, 2) fractional unit-segmenting scheme. Thus, this study provides a clue for curing a fragmentary approach to teaching whole number division and fraction division and preventing students' fragmentary understanding of the same arithmetical operation in different number systems.

The purpose of this study is to investigate the differences in the meanings of two $7^{th}$ grade students over 'a' in expressing and interpreting a function of the form of 'y=ax+b(a, b is a constant, $a{\neq}0$)', and to identify causes of the differences. We collected data from a teaching experiment with four $7^{th}$ grade students who participated in 23 teaching episodes. Analysis of the collected data revealed marked differences between student A and student B in expressing and interpreting given situations with linear functions. The differences between the two students and the causes of differences were also analyzed. The results show that the students expressed and interpreted 'a' in the linear function 'y=ax+b', on the basis of their construction of quantities and their quantitative relationships in a given situation involving a constant rate of change.

The purpose of this thesis was to design and develop an effective e-PBL(Problem-Based Learning) for cultivating consciousness of information and communication ethics. The proposed e-PBL is based on PBL which is one of the constructivism teaching-learning theories. Online learning and face-to-face classes were systematically combined for achieving the teaching-learning goals. And the main module for online learning run on Moodle, an open source learning management system. To examine educational effectiveness of the proposed e-PBL, an experimental study was conducted through the education content and method to the subject of two class in the second-grade of university located in OO city. For experiment 60 students(treatment group=30, control group=30) are participated. And they were randomly assigned to one of ten subgroups, comprising of six students, respectively. The results of this study showed that the education using proposed e-PBL is more effective in cultivating consciousness of information and communication ethics and learners responded positively than the education using traditional face-to-face PBL learning method.
