This study is focused on how the science gifted students can improve their system thinking by applying 3-steps mind map activities about astronomy contents. Through the pre-study two times, 9 students in 6th grade were participated in this study. It was analyzed the degree of improvement of systems thinking through the science gifted students' mind maps, causal maps and their interviews. The results of the study showed that the experimental group's system thinking who learned 3-steps mind map activities was more complex and diverse than the controlled group's. Therefore 3-steps mind map activities that have been developed in this study will be valuable as an alternative to improve their system thinking. Through this study, 3-steps mind map activities were confirmed that by inducing background knowledge activation and thinking systematization can be an alternative to improve the system thinking of science gifted students. So the 3-steps mind map activities can be helpful in cultivate human resources with creative problem solving ability based on their system thinking.

This study identified essential areas of student satisfaction by presenting questions concerning each educational area. The measurement tool of this study was developed based on a literature review, and its validity and reliability were verified through qualitative research and exploratory and confirmatory factor analysis. To measure student satisfaction in university, we developed a tool comprising seven areas: curriculum and instruction; student advising, educational environment, student support, campus life, university image, and administrative services. A total of 54 questions were prepared, and 7 factors were derived. Cronbach's alpha was 0.970 for all questions and ranged from 0.70 to 0.93 for each factor. The results of the confirmatory factor analysis were GFI 0.830, CFI 0.916, TLI 0.910, RMR 0.047, and RMSEA 0.047, which confirmed the suitability of the research model. Moreover, the convergent validity showed that the questions in this tool consistently described the component areas. Therefore, the research tools developed in this study were found to be suitable for measuring student satisfaction.

This study analyzed student noticing in a lesson that emphasized relational understanding of equal signs for first graders from four aspects: centers of focus, focusing interactions, mathematical tasks, and nature of the mathematical activity. Specifically, the instructional factors that emphasize the relational understanding of equal signs derived from previous research were applied to a first-grade addition and subtraction unit, and then lessons emphasizing the relational understanding of equal signs were conducted. Students' noticing in this lesson was comprehensively analyzed using the focusing framework proposed in the previous study. The results showed that in real classroom contexts centers of focus is affected by the structure of the equation and the form of the task, teacher-student interactions, and normed practices. In particular, we found specific teacher-student interactions, such as emphasizing the meaning of the equals sign or using examples, that helped students recognize the equals sign relationally. We also found that students' noticing of the equation affects reasoning about equation, such as being able to reason about the equation relationally if they focuse on two quantities of the same size or the relationship between both sides. These findings have implications for teaching methods of equal sign.

In this study, a restriction enzyme mapping inquiry experiment was developed for cultivating basic knowledge on molecular biology and the effects on inquiry experiment ability and positive experience on science through student-centered molecular biology inquiry experiment class for second graders of a general high school was analyzed. First of all, it was found that the experimental class through the inquiry experiment was significantly effective as the percentage of high school students who answered 'yes' or higher in the positive science experience of general high school students was higher after than before the test. As a result of developing and applying a series of five classes for the creation of restriction enzyme maps, not only did the students' interest in science studies, but also their class participation increased. They were also used as effective specific science learning motives, science career aspirations and experience data. The science environment of the inquiry experiment class led to the improvement of students' learning attitudes and positive science experience, which had a positive effect on the importance of class concentration and class quality, active communication and mutual cooperation among students. In addition, inquiry and experiment classes will provide opportunities for career experience, which will become the foundation for cultivating basic knowledge on molecular biology and advancing to science and engineering.

The purpose of this study is to investigate the difficulties of teachers and students on the unit about 'measuring weight.' In this research, we have acquired data about teachers through survey, interview, and self-reflection journals, at the same time we have collected information on the students through survey, assessment test, and interview. We have extracted the difficulties from analysis with constant comparison method. In addition, we have analysed the curriculum of science and mathematics to know the leaning sequence. The analysis had been checked up by experts in science education. The result of the study is as follows: The difficulties of teachers are from the lack of teachers' descriptive knowledge, disorder of conceptual hierarchy in the curriculum, poor experimental instruments, and low psychomotor skill of students. The difficulties of students are from common misconceptions, opaque concepts, lack of manipulation skill, insufficiency of mathematical ability, difficulty of application of principles to the real situation, and lack of problem-solving ability. In addition, teachers have recognized that students face more difficulties in experiment class, while students think that they face more difficulties in conceptual understanding class.

Small Group Collaborative Instruction in school settings has been endorsed by many educational experts over the years. Some studies found that learners greatly benefit from one another through communication and interaction with their peers. These studies previously indicated improvement of a learner‘s academic ability as well as the application of the affective domain when using this type of instruction. Lower-level students with limited mathematical abilities improved their problem-solving and conceptual thinking skills when tasked to work with other learners. On the other hand, the effectiveness of this process was questioned to be less evident with higher-level performers. Therefore, this study was designed to observe the efficacy of Small Group Collaborative Instruction on higher-level students and to explore their learning process as they interact with and teach lower-level students. This study observed that higher-level students use high-level mathematical thinking skills when helping lower-level students, and they improved problem-solving ability as well as communication skills.

Although Internet provides a lot of convenience such as easy accessibility, interactivity, concurrency, openness, subsequent dysfunction causes serious problems. Especially elementary school students are indiscriminately exposed to the problems, and thus information communication ethics education is needed for the students. This study conducted a survey with randomly selected 5th and 6th graders in Chungbuk area, and analyzed 'students' experience and perception related to information dysfunction' and 'their experience and perception related to information & communication ethics education at school'. In addition, for the detailed understanding of students' current status and accompanying instructional approach, an additional analysis was conducted to examine the existence of the difference according to students' gender and grade. As a result, significant differences were found according to students' gender and grade in their experience and perception related to the information dysfunction and information & communication ethics education. Considering such differences according to students' gender and grade, appropriate instructional approach needs to be prepared to satisfy students' needs for more effective information & communication ethics education.
