This thesis aims to know about the effect science club activities have on the students' science-related attitude. The subjects are 551 high-school students who consists of the students who participate in science club activities and students who don't participate in science club activities. The questionnaires include the questions about cognition of science, interests toward science, and scientific attitudes which belong to the affective domain of Science. The answers are analyzed using by SPSS 11.5 program. This survey shows that whether or not students participate in science club activities affects the cognition of science, the interests toward science, and the scientific attitudes. In other words, science club activities affirmatively enhance the cognition of science, cultivate the thinking power about science, enlarge problem-solving ability by knowing how to survey natural phenomenon, increase the insight into science and help to cope with technological changes. Therefore, since science club activities affect the cognition of science, the interest toward science, and the scientific attitudes in the affective domain of Science, much consideration and concern should be given to science club activities so that students can cherish science club activities and deal with club activities with more attention.

Inquiry-centered education is important in science education, but in the actual education field, scientific research is being done in a uniform manner due to realistic difficulties. In this study, we use RS (Reverse Science) as a secondary chemistry class to provide opportunities for students to engage in inquiry learning and scientific thinking through process-oriented activities. In this study, we developed and applied it to explore the effects on the scientific inquiry abilities of middle school students and checked the students' perception of it. For the application of the program, 128 students were selected from 6 classes of the 2nd grade in D district middle school, 64 from the experimental group and 64 from the comparative group. The experimental group taught RSP-based the chemistry inquiry programs and the comparative group taught instructor-led classes and verification experiments on the same topic over the seventh hour with three themes. In addition, we analyzed the results of the pre- and post-test by using the science inquiry ability test, and discussed the effects of the program based on the students' perceptions through class observation, student activity area, questionnaire and interview. As a result, the class using the program showed statistically significant changes in the science inquiry ability of secondary school students. Specifically, the experimental group was found to be significant in its prediction among the subcomponents of basic exploration ability compared to the comparative group. The differences have also been shown to be significant in terms of data translation, hypothesis setup and variable control, which are subcomponents of integrated exploration capabilities (p <. 05). In addition, students became interested in the process of creating the theory of science, and were highly interested in collaborating with their friends. It also provided students with opportunities to experience scientific thinking through process-oriented inquiry. Finally, based on the positive impact of the RSP-based chemistry inquiry program on students, we were able to identify the potential use of the program.

This study investigated the change of pre-service elementary teachers' professional visions through video-based reflection on science teaching with focus on their attention and pedagogical reasoning about student learning. Specifically, we compared two reflection cycles before and after pre-service elementary teachers went through the collaborative video-based reflection process in a professional learning community. The primary data were collected from eight pre-service elementary teachers and included their science lesson plans, videotaped lessons, video-reflection papers, and transcripts from the interviews. Pre-service elementary teachers' attention was categorized in five aspects: classroom management & control, teacher's instruction, students' thinking & learning, subject knowledge, and assessment. The level of their pedagogical reasoning about student thinking and learning was determined with six levels based on the number of evidence, evidence area, and evidence type. The findings revealed that 1) individual reflection is not enough - collaborative reflection is essential to change their attention toward students learning and thinking 2) pedagogical reasoning levels increase gradually throughout the individual and collaborative video-based reflection processes. The participants not only attributed student learning solely to the characteristics of students but also connected it with their own instruction or science content knowledge and used different types of evidences as they went through two reflection cycles. Implications for using video in the teacher education program were discussed.

Recently, Information Communication Technology(ICT) is one of the most important technology that supports the modern society. As the ICT rises, the needs of the nurturing talents, who can develop a service or hardware on the basis of the humanities increases. As a result, teaching programming skills to students studying humanities and social science are essential. Also, it is important to train students studying science and engineering to write their thoughts logically. In order to serve these students, we introduce a pedagogy for computer programming using programming essay. Since a program is a sequence of the operations based on the programmer's logical thinking, programming can be considered as describing programmer's logic in the proper order using programming syntax. In this research, we train students to describe their logic using natural language. Students write down their essays for a given programming problems. Also, we introduce a pedagogy guideline using programming essay.

E-learning is a new teaching model nowadays, and Virtual Reality (VR) technology is reported that the use of virtual reality as an education tool can increase student interests, understanding, and creative learning because of encouraging students to learn by exploring and interacting with the information on the virtual environment. Besides that, LEGOs have long been the favorite of many children. LEGOs provide a mechanism to understand and do for many concepts from spatial relationships to robotics platforms. In this paper, we present a virtual reality application based on the assembly of LEGO-Like bricks to increase math and science learning by improving spatial thinking. It not only encourages students to pursue careers in science, technology, engineering, or mathematics but also enhances learner's ability to analyze and solve problems. The application is built by Processing 2.0 as the easier programming language which is a top-down approach to build the 3D interactive program.

In this study, we develop 15 learning programs to enhance the variable identification and control abilities for the middle school students and analyze the effect of the programs applied to the class. To increase the learning effect of the variable identification and control abilities, we design the programs so that the students can monitor their thinking processes and also they can evaluate the results from their cognitive activities objectively. We analyze the effect of the programs applied to the class and the results show that the test group, which uses the program, marks higher scores in the variable identification abilities compared to the control group. Also, the test group has the increased level of logic to control the variables. Especially, the effect is higher with the students who do not have any logic to control the variables. From the results, we know that it is possible to improve the variable identification and control abilities of the students through the meta-cognitive learning programs developed by us. Furthermore, the results show that the score of variable control abilities positively correlate with that of meta-cognitive level. It means that the meta-cognitive strategy meaningfully increases the variable control abilities of middle school students.

This study applied the PBL class to the 'Nursing Process and Critical Thinking' courses in the second semester of 2018, and is a primitive research that utilized a single-group, pretest-posttest experimental design in order to examine the effects of the class on Critical Thinking Disposition, Problem Solving Ability, and Professional Self-Concept. Self-report questionnaires were administered to 59 nursing college students in G province. The PBL class consisted of 8 weeks of traditional lectures and 4 weeks of PBL classes. The SPSS/WIN 23.0 program was used for data analysis. Frequency and percentage were used to analyze the general characteristics, and mean, standard deviation and paired t-test were used to analyze the difference between the two groups. As a result, the Critical thinking Disposition of nursing college students was significantly increased(t=4.39, p<.001) after PBL class(3.71±.36) than before PBL class(3.41±.40). The Problem Solving Ability was notably improved(t=3.97, p<.001) after PBL class(3.70±.59) than before PBL class(3.36±.38). The Professional Self-Concept was considerably increased(t=4.84, p<.001) after PBL class(3.22±.50) compared to before PBL class(2.92±.28). Therefore, applying Problem-Based Learning in nursing education to a greater extent is estimated to be effective in increasing the core competencies of nursing college students.
