In this study, the effectiveness of the education program was analyzed through the invention education program using Hands-on Robots, the change of perception of invention and robots of primary and secondary students. The results of the study were as follows: there were many differences in robots that students recognized before and after education, and the change was noticeable in lower grades. In addition, perception of inventions included many robots after they were trained, compared to the fact that robots were not included before they were learned. There has also been a change in attitudes toward robots and their attitude toward inventions, which was more pronounced in the lower grades. By doing so, it can be analyzed that the invention education program using Hands-on robots is effective in giving elementary and secondary students a change in their perception of inventions and robots.

In a 7th graders' cooperative science class, verbal behaviors were categorized and their relationships with the improvement of learning strategies used. motivation, and attitudes were investigated. Students' perceptions of cooperative learning were also studied by the achievement level. Verbal behaviors in cooperative learning were positively related with the improvement of monitoring and organization strategies used, self-efficacy, and attitude toward science class. In the analyses of students' perceptions of cooperative learning, medium- and low-achieving students had positive perceptions but some high-achieving students had negative ones. In the aspect of effectiveness of cooperative learning, especially, medium- and low-achieving students perceived that they could learn more and better due to verbal interactions with peers. To be contrary, high-achieving students perceived that they learned less and superficially.

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.

This study is about investigating students' recognition and expression on relationship of 'time, distance, speed' via teaching experiment. In this process, students showed not only a change in perception of the relationship of 'time, distance, speed' but also recognizing the average speed as a viewpoint of the slope of the line connecting the end points of the interval in the distance function as well as another way of perceiving average speed of a height of a rectangle. In this process, the study shows the scene of expanding the relation of 'distance = time ${\times}$ speed' to 'distance = time ${\times}$ average speed', and also the student who makes the continuous reasoning shows the possibility of constructing a new function that can explain the change of the primitive function by allocating the average rate of change to the interval. Although this study was conducted with a limited number of students, this study suggests some implications through the observation of relationship of 'time, distance, speed' the students'. We hope that these results will be the starting point for various studies for constructing the integral learning model in the future.

The purposes of this study are to develop a measuring instrument for perception of science classes based on the view of 'Community of Inquiry in Science Classroom' and to investigate elementary school students' perceptions with the instrument developed in the study. A total of 417 6th grade students participated in this study. As a result, first, we developed two set of questionnaire: (a) the questionnaire for the 'process of inquiry' consisted of six factors: 'problem recognition I: recognition of inconsistency,' 'problem recognition II: interests,' 'problem explanation I: hypothesis generation and examination,' 'problem explanation II: cooperative review,' 'problem solving I: reflection on the change of relationship with objects/conceptions,' and 'problem solving II: reflection on the change of relationship with community/ inquirer,' comprising a total of 42 items; (b) the questionnaire for the 'basis of inquiry' consisted of three factors:'will of conducting inquiry,' 'attitudes of conducting inquiry,' and 'structure of communication,' comprising a total of 17 items. Second, we found that elementary school students had positive recognition generally on their science classes in terms of the 'community of inquiry in science classroom,' but they had relatively negative recognition on the factors of problem recognition based on recognition of inconsistency, problem solving accompanied with reflection on the change of relationship with objects/conceptions, and attitudes of conducting inquiry based on severity and fallibilism, Finally, several suggestions for the science education were given.

The research carried out to analyze the change of recognition of elementary school students after a forest experience to determine the effectiveness of the environmental education in elementary school curriculum. The data is collected through surveys before and after forest experience for 311 people on 2nd and 3rd grades of two elementary school in Jeonju city, then the conclusions analyzed the results of the surveys are as follows. Students who participated in the forest experience show a positive change in all areas after the forest experience, for example, awareness of the forest and behavior recognition in the forest, the need for commentary about the forest. Especially, the area of the behavior recognition has much significant result than the other areas. In the details of the behavior recognition, a behavior recognition and environmental awareness for the life of the forest have been greatly improved. From the results described above, the forest experience can be seen a great help to elementary school students to have a respect and dignity of life and recognize the importance of the natural environment. Thus, the nature experience such as the forest experience is needed to enhance the life respect and environmental consciousness, foster sensitivity to natural cycles. In order that much more elementary school student can participate in evironmetal education through the forest experience, it would suggest to perform the forest experience as creative and experiential activities in the school curriculum.

This study aimed to generate basic data for enhancing efficiency of education by analyzing and comparing the differences between students and teachers in their attitudes for female teachers'attire. A questionnaire was administered to about 622 students and 176 teachers (from elementary, middle and high schools) in Seoul and Suwon in South Korea. Data obtained from the responses were analyzed using the SPSS program. The results were as follows: First, both students and teachers exhibited higher than average scores in neatness and modesty of female teachers' attire and hair style, and especially teachers considered modesty of attire more important, while students considered neatness of hair style more important. Teachers thought the correlation between attire and efficiency of instruction was high, while students thought otherwise. Also, teachers usually considered teacher' attire more important than students did. Second, according to the results of analysis by school, students in elementary schools considered neatness of female teachers' attire and hair style to be more important than teachers did. On the other hand, teachers in high schools considered it more important than students did. With regard to modesty, the difference between students and teachers became significant in high schools compared to middle schools. In middle and high schools, teachers demanded modest outfits for female teachers more strongly than students did. Across elementary, middle and high schools, teachers exhibited a more positive attitude toward the correlation between what female teachers wear and their teaching efficiency.

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).
