The purpose of this study is to identify elementary school teachers' perceptions, practices, and background factors related to introducing students' everyday experience in science teaching process. The participants of this study were four elementary school teachers who have different features such as major, teaching period, gender, growth area, and age. The data was collected through semi-constructed and in-depth interviews. The results of the research are as follows: Teachers mostly used students' everyday experience during the introduction phase of science lessons for the purpose of motivation. They hold a positive view of using students' everyday experience during science lessons and thought that science teaching needs to actively use more of students' everyday experience, while in actual practice they disregarded or only passively introduced students' everyday experience. The various background factors found to affect teachers' practice are as follows: positive memory on their science class; educational experience of their own children; their own childhood environment; their learning style; their insufficient knowledge or enthusiasm; perceived educational value of everyday life in science education; teacher's duties; importance of students' achievement; difficulty in guiding experiment; reaction of students on introducing everyday experience; characteristics of science textbook and teacher's guidebook; lack of lesson time; realization of national common basic education; characteristics of their students; demands from parents or students; effect of introducing everyday experience. In addition, we found that the teachers behave not in accordance with what they thought due to external factors related to their profession and that, for a more active use of students' everyday experience in their teaching, teachers need support from textbooks and teachers' guidebooks.

In this study, I investigated prospective mathematics teachers' perceptions of activities using Wax-paper, a hands-on material (manipulatives), and GeoGebra, a technological tool, in teaching quadratic curves. Twenty prospective mathematics teachers in the Mathematics Education Department of a local university participated in a survey on their perception of the use of hands-on materials and technological tools in teaching quadratic curves. According to the results of this study, prospective mathematics teachers generally preferred the use of technological tools for learning and teaching quadratic curves. Additionally, mathematics teachers thought that the tool helped students develop intuitive thinking through visualizing quadratic curves, enabling the exploration of various mathematical properties, assisting the comprehension of various concepts, and increasing students' interest levels. However, they were concerned about the immature use of technological tools by students or teachers, and recognized that the advantages and disadvantages of using hands-on material and technological tools were complementary. Based on these findings, it is suggested that hands-on material and technological tools should be used complementally in mathematics classes, and the development and dissemination of class materials that are not affected by students' or teachers' ability to use technological tools is important.

The purpose of the study is to investigate the applicability of portfolio assessment to ordinary elementary science classes, and the effects of a portrolio assessment on students' science achievement, inquiry ability, and science attiudes. Two schools were sampled from a metropolitan area, a city, and three schools from rural area in central Korea. Two fifth-grade classes were sampled from each school selected, and one class is assigned to experimental group and the other to control group, respectively. The total number of participants of the study are 475. Portfolio assessmest was administered to experimental group, and conventional teaching to control group for two and half month. Science achievement test, science inquiry ability test, and science attitudes test were administered as a pre- and post-test. Portfolio asseddment seems to be applecable to ordinary elementary science classroom. Statistically meaningful difference was not found in students' science achievemant by group, region, and sex. Students' inquiry ability and science attitudes showed statistically meaningful difference by region rather than group. Experimental group showed more positive scores on some sub-domains of science attitudes, such as perception on science education, and science career, interests in science activity, and criticism. In conclusion, portfolio assessment can be applicable to ordinary dldmentary science classrooms. The effects of portfolio assessment are at least the same as the traditional teaching on student science achievement, inquiry ability, and science attitudes.

At the present time when the need for universal artificial intelligence education is expanding and job changes are being made, research and discussion on artificial intelligence liberal arts education for non-majors in universities who experience artificial intelligence as part of their job is insufficient. Although artificial intelligence education courses for non-majors are being operated, they are mainly operated as theory-oriented education on the concepts and principles of artificial intelligence. In order to understand the general concept of artificial intelligence for non-majors, it is necessary to proceed with experiential learning in parallel. Therefore, this study designs artificial intelligence experiential education learning contents of difficulty that can reduce the burden of artificial intelligence classes with interest in learning by considering the characteristics of non-majors. After, we will examine the learning effect of experiential education using App Inventor and the Orange artificial intelligence platform. As a result of analysis based on the learning-related data and survey data collected through the creation of AI-related projects by teams, positive changes in the perception of the need for AI education were found, and AI literacy skills improved. It is expected that it will serve as an opportunity for instructors to lay the groundwork for designing a learning model for artificial intelligence experiential education learning.

The purpose of this study was to investigate children's recognition and needs about rest and naps at child care education centers, in the view of respecting children's rights. The participants were 40 children(20 4 year olds and 20 5 year olds), attending B Public Child Care Education Center in Seoul. The research methods were accomplished by participant observation in project activities and interviews with semi-structured questions. The collections of this process which were recorded document materials and video materials were analyzed by transcribed method. The results of this study were as follows: First, the meaning of the children's recognized rest showed time for family together, time for fun play, time required when they were very stressful and angry, and time for eating delicious meals. Second, children recognized that nap time in the child care center was time for a forced nap, time for listening to quiet music, and time for feeling good after a nap. Third, as for the needs to take a rest and a nap for children, they wanted to rest when they came together at full day class after their friends had returned home, they wanted a special area except the classroom, and they wanted to be cared for by familiar adults. Based on these results of the study, future research directions were proposed in terms of respecting children's rights of enjoying a rest and a nap.

ChatGPT, an interactive artificial intelligence (AI) chatbot developed by Open AI in the U.S., gaining popularity with great repercussions around the world. Some academia are concerned that ChatGPT can be used by students for plagiarism, but ChatGPT is also widely used in a positive direction, such as being used to write marketing phrases or website phrases. There is also an opinion that ChatGPT could be a new future for "search," and some analysts say that the focus should be on fostering rather than excessive regulation. This study analyzed consciousness about ChatGPT for college students through a survey of their perception of ChatGPT. And, plagiarism inspection systems were prepared to establish an education support model using ChatGPT and ChatGPT. Based on this, a university education support model using ChatGPT was constructed. The education model using ChatGPT established an education model based on text, digital, and art, and then composed of detailed strategies necessary for the era of the 4th industrial revolution below it. In addition, it was configured to guide students to use ChatGPT within the permitted range by using the ChatGPT detection function provided by the plagiarism inspection system, after the instructor of the class determined the allowable range of content generated by ChatGPT according to the learning goal. By linking and utilizing ChatGPT and the plagiarism inspection system in this way, it is expected to prevent situations in which ChatGPT's excellent ability is abused in education.

According to technology acceptance model(TAN) which is one of the most important research models for explaining IT users' behavior, on intention of using IT is determined by usefulness and ease of use of it. However, TAM wouldn't explain the performance of using IT while it has been considered as a very good model for prediction of the intention. Many people would not be confirmed in the performance of using IT until they can control it at their will, although they think it useful and easy to use. In other words, in addition to usefulness and ease of use as in TAM, controllability is also should be a factor to determine acceptance of IT. Especially, there is a very close relationship between controllability and ease of use, both of which explain the other sides of control over the performance of using IT, so called perceived behavioral control(PBC) in social psychology. The objective of this study is to identify the relationship between ease of use and controllability, and analyse the effects of both two beliefs over performance and intention in using IT. For this purpose, we review the issues related with PBC in information systems studies as well as social psychology, Based on a review of PBC, we suggest a research model which includes the relationship between control and performance in using IT, and prove its validity empirically. Since it was introduced as qa variable for explaining volitional control for actions in theory of planned behavior(TPB), there have been confusion about concept of PBC in spite of its important role in predicting so many kinds of actions. Some studies define PBC as self-efficacy that means actor's perception of difficulty or ease of actions, while others as controllability. However, this confusion dose not imply conceptual contradiction but a double-faced feature of PBC since the performance of actions is related with both self-efficacy and controllability. In other words, these two concepts are discriminated and correlated with each other. Therefore, PBC should be considered as a composite concept consisting of self-efficacy and controllability, Use of IT has been also one of important areas for predictions by PBC. Most of them have been studied by analysis of comparison in prediction power between TAM and TPB or modification of TAM by inclusion of PBC as another belief as like usefulness and ease of use. Interestingly, unlike the other applications in social psychology, it is hard to find such confusion in the concept of PBC in the studies for use of IT. In most of studies, controllability is adapted as PBC since the concept of self-efficacy is included in ease of use explicitly. Based on these discussions, we can suggest perceived use control(PUC) which is defined as perception of control over the performance of using IT and composed of controllability and ease of use as sub-concepts. We suggest a research model explaining acceptance of IT which includes the relationships of PUC with attitude and performance of using IT. For empirical test of our research model, two user groups are selected for surveying questionnaires. In the first group, there are freshmen who take a basic course for Microsoft Excel, and the second group consists of senior students who take a course for analysis of management information by Excel. Most of measurements are adapted ones that have been validated in the other studies, while performance is real score of mid-term in each class. In result, four hypotheses related with PUC are supported statistically with very low significance level. Main contribution of this study is suggestion of PUC through theoretical review of PBC. Specifically, a hierarchical model of PUC are derived from very rigorous studies in the relationship between self-efficacy and controllability with a view of PBC in social psychology. The relationship between PUC and performance is another main contribution.

It is very meaningful to research on how people's perception on equality and psychology on class movement can have effect on the entrepreneurial intention at the present time when the Korean Government persuades people to create new businesses and the polarization between the rich and the poor gets severe. Accordingly, in this study, an empirical analysis was conducted to find out how the proportional equality acceptance level can affect the entrepreneurial intention via the upward mobility expectation by considering the proportionate equality acceptance level as independent variable, upward mobility expectation as a medium variable and the entrepreneurial intention as a dependent variable and then the hypothesis was tested through regression analysis. The results are as follows. First, it was found that the proportional equality acceptance level over the results makes a positive (+) effect on the entrepreneurial intention and the upward mobility expectation. On the other hand, it was found that proportional equality acceptance level over opportunity does not make any significant effect on each of entrepreneurial intention and upward mobility expectation. Second, it was found that the upward mobility expectation makes the positive (+) effect on the entrepreneurial intention. Third, it was found that the proportional equality acceptance level over opportunity and equality acceptance level over the results makes a positive (+) effect on the entrepreneurial intention through upward mobility expectation as a medium, thus showing the partial effect. This study has critical implications as it is an empirical analysis for finding out how the individual's level of perceiving equality makes an effect on entrepreneurial intention and testing the upward mobility expectation's mediating effect, thus reflecting the current society's situation.

Human anatomy courses are one of the most fundamental subjects taught to students in any health-related science field. To improve the quality and to enlarge the scope of human anatomy courses, 130 students (Biomedical Laboratory Science, Physical Therapy, and Occupational Therapy) were given a questionnaire survey. The students were asked question regarding their anatomy course and cadaver dissection class. Specific questions regarding knowledge acquisition before and after the course was queried, in addition to their views on the necessity of cadaver dissection. The survey results indicated that students of all three departments were satisfied with the anatomy course, with no statistical difference in the students' sex or department affiliation. Although there was no difference between the three majors with respect to understanding the course materials, Biomedical Laboratory Science students showed higher satisfaction in this course (p<0.05). Most students, regardless of sex and high school education, stated that cadaver dissection is an important part of the anatomy course. In conclusion, anatomy courses should implement cadaver dissection and actual practice rather than textbook-related studies alone.
