To maximize educational effect with new educational methods in the 4th Industrial Revolution era, immersive education has become the core type of education and virtual reality (VR) is at the center of realistic content. VR education is increasing in school, but researches on VR production education are insufficient. Our study has proposed a school-level curriculum for students to create their own VR content. The output and the survey results were analyzed to find out the learner characteristics of elementary school students, middle school students, and pre-service teachers at each school level. As a result, there were some noticeable differences in concentration, content subject, and production time according to school level. Primary school students focused on their subjects, middle school students related to learning, and pre-service teachers put top priority on contents useful for primary education.

The rapid development and progress of information and communication technology are bringing about changes in the field of education, and innovative methods in teaching-learning have been introduced and applied a lot in the actual field starting with the pandemic. Reflecting this trend, the purpose of this study is to examine the perception of prospective elementary school teachers on the use of edutech, which is widely used in the educational field after COVID-19. To this end, I analyzed the results of 7 major ideas selected at the Edutech Utilization Competition held by K University of Education and the focus group interview conducted with 2 pre-service teachers. As a result of the analysis, it was found that prospective elementary school teachers valued the necessity and importance of edutech-based classes. In addition, they were positively aware of the educational effect of edutech-based classes. To sum up, it could be predicted that edutech classes are also linked to the policies and plans of the Ministry of Education, and will play an important role in effectively guiding future learners while achieving the goals set by the curriculum.

This study investigates the relationships between rhythm and fluency indices and listeners' ratings of the rhythm and fluency of Korean college students' English paragraph reading. 17 university students read and recorded a passage from "The North Wind and the Sun" twice before and after three months of English pronunciation instruction. Seven in-service and pre-service English teachers in graduate school assessed the rhythm and fluency of the utterances. In addition, the values of 14 indices of rhythm and fluency were extracted from each speech and the relationships between the indices and the listeners' ratings were analyzed. The rhythm indices of the speakers in this study did not differ significantly from those of native English speakers presented in previous studies in %V, VarcoV, and nPVIV, but were higher in ΔV, ΔC, and VarcoC and lower in speech rate. The level of rhythm and fluency demonstrated by Korean college students was comparable, at least in terms of objective values for certain indices. The fluency indices, such as percentage of pauses, articulation rate, and speech rate, significantly contributed more to predicting both rhythm and fluency ratings than the rhythm indices.

The purpose of this study is to examine the differences of perceptions of teachers and students regarding teaching skills. For the analysis, data was collected by ICALT(International Comparative Analysis of Learning and Teaching) class observation tool and students survey called My Teacher Questionnaire. a student survey. The data of teachers and students can be compared because as the two tools have seven common domains(Safe and stimulating learning climate, Efficient organization, Clear and structured instructions, Intensive and activating teaching, Adjusting instructions and learner processing to inter-learner differences, Teaching learning strategies, Learner engagement). In 2016, in Daejeon, Chungbuk and Chungnam. trained teachers collected data from 106 classes, and 2,866 students responded the survey. The reliability and validity of the two tools, class observation and MTQ(My Teacher Questionnaire) are proven to be satisfactory for use in Korean schools. Students perception on teaching was high, particularly when students are in lower grades and learning major subjects like English, Korean, and math. The domain of higher teaching skills, male students show higher perceptions while female students reported higher perceptions on lower-level teaching skill domains. To compare the perceptions of teachers and students, the predictive reliability of students engagement against teaching skill domains was used. Teachers showed higher predictive reliability on lower teaching skill domains while students showed higher predictive reliability on higher teaching skill domains. It is recommended for further study to develop a professional development model using a teacher class observation tool and the My Teacher Questionnaire for pre-service teachers and school teachers.

Under the banner "Toward Global Excellence in Teacher Education", Daegu National University of Education has strived for the single aim of excellence in pre-service and in-service for over fifty years. Specially the department of Mathematics education aims to develope students' mathematical power which is related to elementary school mathematical concepts & theories. However not a few of the students seem to have test-anxiety which is relate to teacher recruitment examination. In these view, we conclude that students must have been suffered from test anxiety. Consequently the results of the study are follow. $\cdot$ 2nd paper-pencil test of the elementary school teacher recruitment(2010) has been emphasized on statement of examinee logocal thought about all 10 subjects. $\cdot$ 3rd test of the elementary school teacher recruitment(2010) has been focused on only speaking english of examinee. Thus we conclude that these Recruitment Examination(2010) couldn't minimize the test anxiety of the students. Therefore next test of the elementary school Teacher Recruitment should contain on mathematical problem-solving in elementary school mathematics textbooks.

This study aims to test the efficacy of English-based automated computer scoring models and machine translation to score Korean college students' written responses on natural selection concept items. To this end, I collected 128 pre-service biology teachers' written responses on four-item instrument (total 512 written responses). The machine translation software (i.e., Google Translate) translated both original responses and spell-corrected responses. The presence/absence of five scientific ideas and three $na{\ddot{i}}ve$ ideas in both translated responses were judged by the automated computer scoring models (i.e., EvoGrader). The computer-scored results (4096 predictions) were compared with expert-scored results. The results illustrated that no significant differences in both average scores and statistical results using average scores was found between the computer-scored result and experts-scored result. The Pearson correlation coefficients of composite scores for each student between computer scoring and experts scoring were 0.848 for scientific ideas and 0.776 for $na{\ddot{i}}ve$ ideas. The inter-rater reliability indices (Cohen kappa) between computer scoring and experts scoring for linguistically simple concepts (e.g., variation, competition, and limited resources) were over 0.8. These findings reveal that the English-based automated computer scoring models and machine translation can be a promising method in scoring Korean college students' written responses on natural selection concept items.
