This study brings up that further studies on the perceptions of university students should be conducted for efficient management of student records. Moreover, the Q methodology is used to identify subjective recognition (Q1) type related to the importance of student records and subjective perception (Q2) of student records type. For this purpose, I carried out questionnaires and interviews with eight students by each grade at Chonnam National University. As a result, Q1 type was derived from Collective Evidence type, Independent activity type, Democratic witness type, and achievement-oriented type. The type of Q2 is derived from Historical Value of Community Type, Personal Possession Type, Historical Expert Management Type, Value for Historical Practical Use Type, and Non-historical Preservation Type. Based on the research results, the following are suggested: First, the management of student records is needed in a way that encompasses various records of various records properties. Second, the management of student records should be established from the perspective of the Community Archives. Third, a strategic measure for the preservation of student records produced by students is necessary (e.g., a campaign for conservation of student records).

This study searched secondary school students' epistemological views and ontological views about nature and the root causes of such their views. The subjects were 156 secondary school students and data were gathered by the questionnaire developed based on preceding researches. As a result, many secondary school students had epistemological views of unknowable nature. There were various root causes of their epistemological views such as regularity and harmony of nature, predictable and circular natural phenomenon, causation, the relation between human and nature. On the other hand, a lot of secondary school students had ontological view of supernatural nature. Their religious beliefs were very powerful influence their supernatural ontological views. The nature is the object of science and the physical world. Because those views supply science educators basic backgrounds how leaners understand science class, secondary school students' epistemological views and ontological views are precious information. From now on, it is necessary to study relations between students' epistemological views and ontological views and their science class processes.

This study investigated middle and high school students' perceptions of scientific literacy in the $21^{st}$ century through the survey. Subjects were 952 students from 13 participating schools. 482 middle school students and 470 high school students, 471 male students and 481 female were involved. The survey questionnaire asked which elements they thought would be important to be scientifically literate in the $21^{st}$ century and why they chose the elements. The results showed that most of the students tended to focus on orientation, content knowledge, and mindset. A large portion of female students showed orientation was the most important element. On the other hand, male students showed that scientific knowledge as well as orientation was important.

Convolutional neural network (CNN) generally uses two-stream architecture RGB and optical flow stream for its action recognition function. RGB frames stream display appearance and optical flow stream interprets its action. However, the standard method of using optical flow is costly in its computational time and latency associated with increased action recognition. The purpose of the study was to evaluate a novel way to create a two sub-networks in neural networks. The optical flow sub-network was assigned as a teacher and the RGB frames as a student. In the training stage, the optical flow sub-network extracts features through the teacher sub-network and transmits the information to student sub-network for baseline training. In the test stage, only student sub-network was operational with decreased in latency without computing optical flow. Experimental results shows that our network fed only by RGB stream gets a competitive accuracy of 54.5% on HMDB51, which is 1.5 times better than that on R3D-18.

The purpose of this study was to investigate relations between middle school science teachers' perception of students' learning styles and their teaching style. Data were collected by in-depth individual interviews with 20 experienced science teachers (14 years of teaching experience in average). Results indicated four categories of the relations: i.e. teachers implemented their teaching style (1) matching students' learning styles, (2) supplementing students' insufficient learning styles, (3) teacher-centered, but matching the diverse students' learning styles, and (4) based on their values and convictions. In general, teaching styles of the teachers did not match with their perceptions of students' learning styles. Instead, their teaching styles seemed to be more affected by their personal values and convictions.

The STEAM education was applied to science high school students, and changes in perceptions of students and teachers were investigated after class treatment. By the results of the student's perception survey, very positive results were found in increasing problem-solving capabilities, educational satisfaction, etc. More than 98% of students said they would continue to participate in STEAM education classes. Meanwhile, the lack of time for class activities put a burden on students to complete the problems during class. Especially nanoscience content and activities were properly organized in consideration of the level of cognitive development of the students. In addition, as a result of a survey of teachers' perceptions for students, more than 80.0% of teachers responded very positively in 'self-directed learning ability' and 'problem-solving capability', etc.

The purpose of this study was to investigate perceptions of high school students and science teachers about high school fusing science. Science teachers and high school students perceived that high school fusing science was related to various areas and they preferred to be taught separately from each area. Science teachers perceived that high school fusing science improved the understanding in the area of scientific common knowledge, advanced technology, and the history of science, but neither scientific writing nor discussion were actively involved. It also didn't contribute to the enhancement of scientific thinking and communication skill. Especially, high school students believed that they were more interested in science through fusing science. On the other hand, teachers believed that this high school fusing science might not impact student's learning and generate negative perception. Science teachers and students perceived that they were more interested in fusing science because it was combination of many areas in science. They also perceived that contents in fusing science were more related to their daily life.

The purpose of this study is to explore secondary school teachers' perceptions of student evaluations, focusing especially on students' performance in the classroom. The study selected Germany as a representative country where teachers' performance evaluation strongly affects students' school pathways. The researchers selected 4 English teachers and conducted in-depth interviews with them. The results indicated that German English teachers perceived students' performance as an individual evaluation and provided each student with oriented learning materials and evaluation results. The second, they used formative evaluations to confirm and motivate their students' learning process as well as peer assessments. The third, the German English teachers showed strong empowerment in the evaluation process. The fourth, they motivated to participation in-class activities teacher through performance evaluation considering fairness. Based on the results, future studies should need to observe real settings in the classroom and students' perceptions of their evaluations. the study also suggested using practical performance evaluations to enhance students' motivation and participation in the classroom. This study identified limitations of the research and made significant recommendations for future studies.

The purpose of this study was to examine middle school students' (N= 153) perceptions of motivational climate (teacher learning/teacher comparison/peer learning/peer comparison/peer worry) and their achievement goals (task/performance/performance-avoidance). The influence of perceptions of motivational climate emphasized by science teachers and/or peers on achievement goals was explored by stepwise regression. Although there was no difference in male/female perceptions of motivational climate, there was significant difference in their achievement goals. Regression result indicated that the pursuit of learning by peers made the strongest contribution to students' task goal. On the other hand, promotion via comparison by science teachers or peers had little effect on inducing performance goal. Anxieties about mistakes were found to be the strongest contribution to predictions on students' performance-avoidance goal. The promotion of comparison by science teachers was related to not only performance goal, but also performance-avoidance goal. Lastly educational implications for intervention efforts designed to enhance the quality of student motivational development in science education are discussed.

The purpose of this study was to find out how interest in thermal concepts and the perceived difficulty affect the stimulation of science state curiosity. To achieve this purpose, 410 elementary school students in 5th to 6th grade were asked to measure interest in the content of the thermal concept tasks, the perceived difficulty and science state curiosity while solving the thermal concept tasks. 2 (low interest vs. high interest)×2 (easy vs. difficult) ANCOVA was conducted with the covariate of the student's level of science curiosity, which is expected to affect the stimulation of science state curiosity. As a result of the analysis, students with high interest in the contents of the task were showed high science state curiosity. Meanwhile, there was no difference in the level of science state curiosity according to the perceived difficulty. In addition, science state curiosity level of the students with low interest in the content of the task were high when they perceived the task as easy, but science state curiosity level of the students with high interest in the content of the task were high when they perceived the task as difficult. This study was meaningful in that it empirically verified that interest in the content of the tasks has an effect on the stimulation of science state curiosity, and that the effect of interest on the stimulation of science state curiosity varies according to the level of the perceived difficulty.
