The rapid advancement of generative AI has ushered in an era where anyone can create and freely utilize personalized chatbots without the need for programming expertise. This study aimed to develop a customized chatbot based on OpenAI's GPTs for the purpose of pre-service teacher education and to analyze its educational performance in mathematics as assessed by educators guiding pre-service teachers. Responses to identical questions from a general-purpose chatbot (ChatGPT), a customized GPTs-based chatbot, and an elementary mathematics education expert were compared. The expert's responses received an average score of 4.52, while the customized GPTs-based chatbot received an average score of 3.73, indicating that the latter's performance did not reach the expert level. However, the customized GPTs-based chatbot's score, which was close to "adequate" on a 5-point scale, suggests its potential educational utility. On the other hand, the general-purpose chatbot, ChatGPT, received a lower average score of 2.86, with feedback indicating that its responses were not systematic and remained at a general level, making it less suitable for use in mathematics education. Despite the proven educational effectiveness of conventional customized chatbots, the time and cost associated with their development have been significant barriers. However, with the advent of GPTs services, anyone can now easily create chatbots tailored to both educators and learners, with responses that achieve a certain level of mathematics educational validity, thereby offering effective utilization across various aspects of mathematics education.

The purpose of this study was to examine whether there was a difference in the recognition and teaching strategies for the young child's behavioral problems according to teachers' socio-demographic variables and ego-resiliency level by analyzing survey responses from 238 teachers of 3, 4, and 5-year-old children. This study found that the group of teachers with the education level of junior college graduation or higher showed higher degree of recognition of children's behavioral problems than the group of teachers with a lower level of education. And the group of teachers at kindergartens showed a higher degree of recognition of children's behavioral problems than the group of teachers at day care centers. Regarding the difference according to the level of ego-resiliency, the group of higher ego-resiliency showed higher degree of recognition of children's behavioral problems than the group of lower ego-resiliency. In terms of teachers' teaching strategies for the behavioral problems, differences were recognized at sub-categories. To explain, differences were recognized in accordance with the teachers' age and career as well as their education level and work place; the higher the teachers' age, career, and education the more often they used the positive prevention strategy I. And teachers at kindergartens resorted to the negative response strategies more often than those at day care centers. Finally, the teaching strategies for the behavioral problems according to the teachers' ego-resiliency, group differences were seen in all the sub categories. The result of this study suggested that the need to develop and apply such programs for pre-service teachers and for teacher reeducation reflect those variables.

Due to the importance of biotechnological literacy, the educational community in fields such as technology education, science education, and agricultural education has acknowledged the importance of biotechnology instruction for secondary school. Although recognized as a content organizer in the field of technology education, the actual teaching of biotechnology has not been broadly implemented in technology education classes. In the perspective of expectancy-value theory, technology teachers' motivation is the key factor for affecting the biotechnology instruction. This study investigates Korean technology teachers' motivational beliefs toward biotechnology and its instruction and their perceived ability and value toward biotechnology learning contents. To measure their motivational beliefs and attitudes, a composite on-line survey (fifteen motivational beliefs items, eight biotechnology content items, and related demographic items) was developed. Based on 114 Korean technology teachers' responses the researcher performed a descriptive analysis, independent t-test, and factor analyses (exploratory and confirmatory factor analysis using M-plus 5.0 and SPSS 16.0). Korean technology teachers' abilities toward eight biotechnology contents indicated lowscores while their values were relatively high. Through the independent sample t-test by two demographic variables (gender and professional development), this study found several significant differences in the perceived value. As a preliminary finding of exploratory factor analysis, fifteen items was separated into two motivational constructs of expectancy (6 items) and value (8 items). One item (item #6) was eliminated due to the cross loading. The final findings of this study may have significant implications for professional development regarding biotechnology and its instruction (both in-service and pre-service training) of technology teachers. Also, the confirmatory facctor analysis supported the preliminary finding. Finally, this study recommends that a validity test for other population, investigation for motivational sub-constructs, and in-depth investigation toward biotechnology instruction.

The purpose of this study was to investigate home economics teachers' perception of cultural diversity education, to provide an efficient educational material for the multicultural education in teacher education and teacher retraining. 160 Home economics teachers answered the survey questionnaires. To analyze the data, SPSS 19.0 for Windows was used to conduct frequency analysis, factorial analysis, credibility analysis, t-test, one-way ANOVA, and Duncan's multiple comparison. The results of this study were as follows. Four dimensions of cultural diversity education were derived by factor analysis: cultural equality, diversity implementation, diversity value, comfort with diversity. As for their awareness about cultural diversity education, it was in the order of cultural equality, followed by diversity implementation, diversity value, and comfort with diversity. The groups were significantly different according to demographic variables. As for the whole awareness about cultural diversity education and the diversity implementation, group of age 40 teachers recognized more highly than other groups. Furthermore, teachers outside Jeonbuk area recognized more highly the cultural equality, diversity implementation, diversity value than those in Jeonbuk, which is the 3rd high area in the nation of multicultural family proportion. As for cultural equality and diversity implementation, teachers over 15 years of experience, recognized more highly than other groups. Those with the teacher certification in the college of education, recognized more highly the cultural equality, diversity value, comfort with diversity than teachers from the other colleges. Teachers who need multicultural education, recognized more highly cultural equality, diversity implementation, awareness of diversity than those who don't. These results imply that in home economics education, there must be more systematic studies on school field education and related educational programs in order to revitalize multicultural education. And for teachers with highly recognizing cultural diversity to conduct a systematic multicultural education more efficiently, there should be both systematic pre-service education programs at college level and in-service education programs for the teachers in terms of cultural diversity education.

The statement, 'Taking more mathematics would result a better mathematics teacher.' sounds plausible. However, it is questionable that how much of taking university level of mathematics such as abstract algebra and real analysis would affect to teach elementary mathematics well. Would a mathematician be a better teacher for elementary students to teach mathematics than who has been prepared to teach elementary mathematics? This paper reports the effects of opportunities to learn tertiary level mathematics and school level mathematics on pre-service primary school teachers' mathematics pedagogical content knowledge. The study analyzed Teacher Education and Development Study in Mathematics 2008 (TEDS-M 2008) database using multiple regression. Prospective primary teachers who have been prepared as generalist were the focus of the study. The results support future elementary teachers might need to have opportunities to revisit school mathematics they are going to teach.

The purpose of this study is to identify the types and characteristics of elementary school pre-service teachers revealed in the process of resolving the change of lunar phases, which emphasizes the context of actual observation, and to provide suggestions for areas to be considered in the elementary school teacher training program. To this end, we analyzed the 30 pre-service teachers' explaining the observable lunar phases, and the main research results are as follows. First, the phase change of the moon was often explained by introducing the timetable for each phase of the moon rather than based on observation of the phenomenon and scientific reasoning. Second, an alternative concept of the type that the moon is invisible when the sun rises or that the moon can always be observed has been identified. Third, there was a case of explaining that the time and orientation for observing the moon can be observed regardless of the position of the sun or when observing the sun. Also, the date of observing the moon was assumed to be approached by assuming the lunar calendar. Based on the above results, pedagogical implications were discussed.

The purpose of this study was to investigate beginning earth science teachers' perceptions about Learning in Geologic Field Trip. The hundred and sixteen high school earth science teachers who were in the training for their promotion answered the questionnaire of Learning in Geologic Field Trip. It was divided into five parts: needs and educational values, teachers' experiences and their difficulties, and desirable teaching methods of Learning in Geologic Field Trip. Results indicated that the participants perceived Learning in Geologic Field Trip important in earth science education and responded positively to the educational values of Learning in Geologic Field Trip. Most of the beginning teachers had experience of geologic field trip, but did not learn how to teach it to their students during the geologic field trip in the pre-service training program. It was shown that only a few teachers had experience of geologic field trip and of teaching students in the outdoor of geologic fields after they became a classroom teacher. Most of the participants perceived that teaching students about the geologic field trip is difficult because of lack of their experience. In order to overcome the difficulty, teachers suggested that they need to learn how to teach the geologic field trip to students through their in-service training. leachers suggested that a desirable teaching method of the geologic field trip is to provide teachers with a teacher's manual including geological explanation and information about field trip sites before their visit so that they can scaffold it and facilitate the students' cooperative group activity during the field trip. As a follow up activity, the participants agreed that the presentation and discussion about the results should concur.
