This study investigates how the GSP helps gifted and talented students understand geometric principles and concepts during the inquiry process in the generalization of the internal triangle, and how the students logically proceeded to visualize the content during the process of generalization. Four mathematically gifted students were chosen for the study. They investigated the pattern between the area of the original triangle and the area of the internal triangle with the ratio of each sides on m:n respectively. Digital audio, video and written data were collected and analyzed. From the analysis the researcher found four results. First, the visualization used the GSP helps the students to understand the geometric principles and concepts intuitively. Second, the GSP helps the students to develop their inductive reasoning skills by proving the various cases. Third, the lessons used GSP increases interest in apathetic students and improves their mathematical communication and self-efficiency.

Although astronomical observation has various educational effects and values, studies conducted in the context of earth science education have been relatively insufficient compared with other fields. In addition, few studies have been conducted on systematic design principles development guiding teachers in the application of practical astronomical observation education. In this study, we attempted to develop design principles for astronomical observation education programs for K-12 students and applied the program to the classes. The initial design principles were derived through literature research and revised through validation processes by eight experts. The final principles were confirmed based on the usability evaluation of two high school teachers, and they included 11 design principles and 27 detailed guidelines. In addition, an astronomical observation education program consisting of eight lessons was designed by applying the final design principle. This program was applied to after-school classes in high school, the responses of participating students were investigated. We anticipate our design principles can be used as a criterion for systematic design of various types of observation activities, including outdoor observations.

The purpose of this study was to investigate the impact of student assessment activities on claim and evidence formation in argument-based inquiry (ABI) for high school students. The participants of the study were 166 grade 10 students from six different classes in the same high school. The experimental group (84 students) was taught Argument-Based Inquiry with students' self and peer assessment activities. The comparative group (82 students) was taught without the activities. Over one semester students participated in five ABI programs that we developed. According to the analysis of the claim and evidence from groups, the experimental group had a significantly higher mean score than the comparative group. The result of analysis of students' assessment in the experimental group, the frequency about accurate and sufficient evidence revealed to be high and students assessed whether peers' claims fit with the evidence and whether peers' explanations of the evidence's validity was sufficient. Students' answers in the survey and interviews showed that the students though they could improve the accuracy of their ideas, appropriateness of their evidence, and the method of presenting evidence based on the assessment results.

The purpose of this study was to search for effective strategies on teaching open-inquiry by comparing students' and teachers' recognition of its difficulties and helpful strategies. This study focused on the cases of science high school students and their teachers, who carried out open-inquiry to participate in KYPT. This research was conducted through participant observation, questionnaires, and interviews. The research findings were as follows: students stated that planning and doing experiments were the most difficult parts, whereas teachers viewed that their students had difficulties in analyzing data and making a conclusion. With respect to the effective strategy, students stated that they gained many ideas from peer discussions although they have had to carry out their individual tasks. On the contrary, teachers thought that reference materials and the discussions with teachers were most helpful. There were clear differences between students' and their teachers' recognition toward open-inquiry and the gap needs to be closed. Consequently, it would be useful to guide students to form teams and to spend more time in peer discussions especially when doing experiments and to encourage teachers to understand students' actual difficulties and needs.

The purpose of this study was to investigate elementary teachers' views on the barriers in implementing inquiry-based instruction in science education. For this, semi-structured in-depth interviews were performed with 22 elementary school teachers who have served for more than five years in the Gyeonggi province. The interview questions were developed through triangulation of Seidman's phase to achieve reliability in the interview data, then interview questions were modified and completed through an analytic induction method in pre-interviews. In-depth interviews were performed individually and all the interviews were recorded. The data of teachers' views on the barriers were categorized and analyzed into external and internal factors of teachers. The study found that the external factors referred by teachers included the following; the lack of a unit time, lack of materials and equipments, too many students in a class, problems in science curriculum management, difficulty in the assessment of students' inquiry activities, the students' learning, lack of opportunities for teaching inquiry activities, harmfulness of accidents, and so on. Internal factors included the following; lack of preparation for inquiry activities, lack of self-confidence, lack of patience, and so on. The various barriers presented and their causes were analyzed in detail, and possible efforts in activating inquiry activities in elementary science education were suggested.

The purposes of this study were to develop a scientific inquiry-based STEAM education program and to investigate its effect on changing middle school students' self-efficacy in science, job awareness, and attitudes toward STEM. A scientific inquiry-based STEAM program was developed with the theme of 'earthquakes', using the ADBA model, which was taking up the total of six class periods. The final program, which had been revised and completed after being pre-tested with middle school students, was implemented to 105 third-graders of middle school in a metropolitan city. One sample pre-post paired t-test before and after applying the program to the same group was conducted, and its effectiveness was analyzed in terms of self-efficacy in science, job awareness, attitudes toward science, technology, engineering and mathematics. Results showed that the STEAM program on the theme of 'earthquakes' demonstrated its effect on improving the students' of self-efficacy in science subject and their awareness of science-related jobs. Furthermore, this program indicated a statistical significance in improving middle school students' attitudes, awareness, and abilities, values, and continuing interest towards science, technology, engineering, and mathematics. Therefore, we suggest that this scientific inquiry based STEAM program be used to help students to improve their scientific investigation skills as well as their creative and integrated thinking abilities in schools.

The purpose of this study is to explore the changes caused by using smart technology in school science inquiry. For this, we investigated 12 elementary school teachers' perceptions by using an open-ended questionnaire, group discussions, classroom discussions, and participant interviews. The results of this study indicate that the introduction of technology into classroom inquiry can open up the various possibilities and can cause additional burdens as well. First, teachers explained that smart technology can expand the opportunities to observe natural phenomena such as constellations and changing phases of the moon. However, some teachers insisted that, sometimes, learning how to use new devices disrupts students' concentration on the inquiry process itself. Second, teachers introduced the way of digital measurement using smart phone sensors in inquiry activities. They said that digital measurement is useful in terms of the reduction of errors and of the simplicity to measure. However, other teachers insisted that using new devices in classroom inquiry can entail additional variables and confuse the students' focus of inquiry. Communication about inquiry process can also be improved by using digital media. However, some teachers emphasized that they always talked about both the purpose of using SNS and online etiquettes with their students before using SNS. Based on these results, we discussed the necessity of additional analysis on the various ways of using digital devices depending on teachers' perceptions, the types of digital competency required in science inquiry using smart technology, and the features of norms shaped in inquiry activities using smart technology.

In this study, explicit Teaching and Learning strategy for middle school students were developed to improve basic science process skills. After applying these strategy in an actual class, the effects of Teaching and Learning strategy and change of students were analyzed. Explicit Teaching and Learning strategy to improve basic science process skills are developed based on analyzing preceding research. The use of application criteria for class of basic science process skills combined with explicit Teaching and Learning strategy, it is sought for the explicit instructional procedures of said skills. After analyzing the class in which explicit Teaching and Learning strategy were demonstrated, students reported that they were able to comprehend basic science process skills more effectively through the stages of explicit explaining and independent practice. The showing demonstration stage was heavily emphasized by the teacher in this class. Analysis of students' understanding degree about basic science process skills, most of them show positive outcome. Another analysis of ripple effect on daily life and other subjects, it is found that students could have the attitude to make use of science process skills for themselves. Through the result of study, it is found that explicit Teaching and Learning strategy that are developed from this study are an effective way to comprehension students' basic science process skills. Thus, continued study is needed to develop and spread explicit Teaching and Learning strategy of science process skills to be applicable in actual classes in secondary schools.
