The purpose of this study is to construct factors of AI education utilization competency. AI education utilization competency is used as basic data for education to enhance the AI education competency of pre-service early childhood teachers. To this end, 7 studies related to competency factors and models were selected by searching for previous studies. Seven preceding studies were analyzed. As a result, 18 competency factors were extracted, including understanding of artificial intelligence. The extracted competency elements were divided into six areas, which are divided into understanding subject knowledge through coding, class preparation, class management, class result feedback, class guidance, and self-development. And 15 factors were constructed. The draft formed through coding was improved through review by three early childhood education experts. Factors improved through expert review were structured by classifying them into knowledge, skills, and attitudes to organize the curriculum. The validity of the structured competency factor was verified through expert Delphi. As a result of the Delphi verification, all factors were converged in the first survey. Through this, 6 competency areas, 11 competency factors, and 19 competency factors were composed of knowledge, 10 skills, and 5 attitudes. The implication is that the competency factors presented as a result of this study can be used as basic data for organizing a curriculum to improve the ability of pre-service early childhood teachers to use artificial intelligence education.

Along with the increased significance of SW education in the 2015 revision curriculum, SW education using various educational methods and tools is being performed, and teaching and learning contents using SW education tools are continuously being developed. In this paper, we analyzed pre-service teachers' EPL contents preference types, preferred development subjects, and their relationship with pre-service teachers based on the analysis conducted after their EPL class session in which its results were assortatively analyzed by department, letter grade, and type. The result signified a clear difference in development subject and types among the departments, and it also showed a difference in development subject and its recipients among the types. However, there was no difference between development subject and type among the letter grade. This will provide a feedback on EPL classes and help develop EPL-related curricula as well as its application.

This study is to propose a FOCUS Teaching & Learning model to educate pre-service early childhood teachers and in the era of convergence and integration and the Fourth Industrial Revolution. In an era where the use of digital technology is maximized due to COVID-19, boundaries of each fields are blurred and convergence is emphasized, a teaching and learning model is needed to strengthen capabilities of freshmen at colleges that train specialists. This study proposes ways to vitalize ICT education in early childhood education and proposes an integrated teaching and learning model. Through this model, pre-service early childhood teachers will be able to enhance their digital capabilities and contribute to the field of early childhood education by producing video content, activities and teaching aids to be provided to early childhood education institutions. In addition, the model can be applied to areas other than early childhood education to improve digital capabilities through video production and utilization.

The purpose of study was to introduce and propagate the children's verses as the teaching/learning strategies in science education far elementary students and teachers. 238 pre-service teachers, 140 in-service teachers and 602 elementary students wrote the own verses and read colleague's verses with respect to science. In this situation, the writing was considered as creation and the reading was reception and appreciation for the verses. When they wrote the verses, the themes were not restricted except that they were related to science. Mostly, the subjects were something about science concepts, scientific phenomena or experimental instruments, etc. In addition, this study investigated the merits and demerits of the reading/writing activities of children's verses as the teaching/learning strategies in science classroom.

This study is a study of factors affecting pre-service teachers' learning immersion in online science classes. The results of a survey on the responses of 88 pre-primary teachers to online science classes were interpreted. In online science class, independent variables were set as ease, usefulness, and social presence, and dependent variables were set as learning immersion. Online science classes were conducted based on the university's LMS system. The results of the study were interpreted by regression analysis for t-test, correlation between factors, and multicollinearity test in pre-post-responses of pre-service teachers for ease, usefulness, and social presence. The results of this study are as follows. First, there was a significant effect in the before-and-after tests of factors in the online science class. Second, the correlation coefficient between factors in online science class is .306 for sense of community and mutual support and concentration at the significance level of .01, and .354 for learning immersion and open communication, indicating that there is a correlation. Third, considering the effective results of the pre-post test of each factor in the online science class, it cannot be interpreted that a particular factor had an effect, but it is interpreted that learning was immersed in ease, usefulness, and a sense of social presence.

This study aimed to design a robot programming lecture for pre-service mathematics teachers to improve their TPACK-P (TPACK-Programming) and analyze its effectiveness. The lecture design involved stages of analysis, exploration, primary micro-teaching, and secondary micro-teaching, with each stage including design, application, and evaluation. The TPACK-P survey was conducted before and after the lecture, and the results indicated a statistically significant difference in TCK at the 1% significance level and TPK, TRACK, and TRACK(P) at the 5% significance level. Further analysis using dependent sample t-tests showed that the post-test mean was significantly higher than the pre-test mean in categories such as TCK, TPK, TPACK, and TPACK(P). These findings suggest that the designed lecture positively affected the growth of pre-service mathematics teachers' TPACK-P.

In the elementary school science curriculum, wind is one of the most important concept. In particular, land and sea breeze has been a key example to deliver how wind is driven, and thus its model experiments have been used to help students understand causes of wind. Here we compare causes and explanations for wind and land and sea breeze between textbooks in colleges and elementary schools to examine any potential improvement for the contents. In addition, we conducted survey to examine how pre-service teachers understand land and sea breeze, and convection box experiment used in elementary school textbooks is useful to understand land and sea breeze. Based on the comparison, we find that college level textbook explains the cause of wind as atmospheric pressure difference while elementary school textbooks explain them differently according to curriculums. In the textbooks, there are a difference in the way described for land and sea breeze. Analysis of questionnaire indicate that pre-service teachers understood land and sea breeze correctly, and they selected the convection box experiment in 2009 curriculum textbooks as the most suitable one. Explanations and experiments for land and sea breeze in the textbooks have been revised as the modification of elementary school curriculums. We expect this study helps to deliver more solid contents for wind and land and sea breeze in the upcoming new curriculum.

The purpose of this study was to investigate the conceptual structure of subjects related to matter having pre-service elementary school teachers by applying semantic network analysis (SNA). The analyzed concepts in the subjects of matter were 6 words such as 'atom', 'molecule', 'ion', 'electron', 'matter' and 'particle'. The results of SNA of the concepts are as follows : 1. In the semantic network of 'atom', words having a high betweenness centrality were linked with the words based on both the scientific context and the everyday context. 2. The network of 'molecule' was analyzed to be more organized than the network of the 'atom'. 3. In the network of 'ion', the group of words of the scientific context was distinguished from the group of words of the everyday context. 4. The network of 'electron' was analyzed to be more oriented on electricity and magnetism in the field of physics. 5. In the network of 'matter', the words related to compounds were linked with knowledge of history of science. 6. The network of 'particle' was not structured with words based on particulate nature of matter.

To improve oral hygiene management, the effects of toothbrush training on general oral hygiene based on the simplified oral hygiene index(S-OHI) and degree of knowledge about toothbrushing were examined. Pre-and post-training changes in the S-OHI (lower score = better oral health status) showed a significant decrease in score in all variables (gender, age, marital status, occupation, and level of education).Pre- and post-training changes in the degree of knowledge about toothbrushing showed a significant increase. Negative correlations between the S-OHI, oral health status, and degree of knowledge about toothbrushing and the S-OHI and the Decayed, Missing, Filled (DMF) index (the better the oral cavity environment, the lower the DMF index) were observed. Positive effects of repeated toothbrush training on the maintenance of healthy oral cavity environment and continuous oral health management were observed, as reflected by the correct toothbrushing-related knowledge and skills.
