The purpose of this study is to develop a software education program using micro:bit based on the ADDIE development model and to analyze the effects of the development of creativity of elementary school students. The education program was developed based on the results of the pre-demand analysis conducted on 40 elementary school teachers in Jeju. In order to verify the effectiveness of the developed education program, 42 students who participated in the education donation program conducted by ${\bigcirc}{\bigcirc}$ University were enrolled in 24 hours for 7 days for 6 days. The results of the analysis show that the software education program developed in this study has positive effects on the creativity factors by improving the programming ability of elementary school students.

In this study, we developed a data science education program using spreadsheet, applied it after educational method to improve elementary school student 's Computational Thinking, and then verified its effect. Based on the results of preliminary requirement analysis conducted by Rossett's request analysis the educational program was developed based on the procedure of the ADDIE model which is the representative model of the teaching design based on the result of prior requirement analysis of 205 elementary school students and computer teaching major 20 incumbent elementary school teachers, applying Rossett's requirement analysis model. In order to verify the effect of the developed educational program, we are promoting 42 hours of lecture for a total of 6 days for 20 students of applicants who volunteered for volunteer votes of educational donation programs implemented at ${\bigcirc}{\bigcirc}$University, We analyzed the educational effect using the results of pre-post test. As a result of the analysis, we learned that the educational program developed in this study is effective for improving elementary school student 's Computational Thinking.

This study aims to analyse the effectiveness of the mathematics teacher's training program: whether the training program is effective to improve mathematics teachers' professional competency of the developing assessment instrument (including items) or not. The teachers who were attendee of the program did pre-test before the program and post-test after the program. They wrote the opinions on the pre-developed items which had many errors in the beginning and discussed their opinions each others in the middle of program. The differences between pre-test and post-test and between opinions in the beginning and in the middle were analysed. The first result of the study is that the teacher's professional competency which is evaluated as self-perceived points is improved with regard to understanding the standardized test, item difficulty and item discrimination. Secondly, the proportion of the opinion with concrete reasons is increased as the program progressed. Thirdly, the effective elements of the program are the discussion in the group, discussion between groups, and feedback from the instructor. But the ineffective element of the program is the insufficient time for practicing.

This study analyzed the effect of an unplugged educational program which focuses on the algorithm execution time analysis on enhancing the computational thinking of the third grade students. An unplugged educational program was developed by following the procedures of the ADDIE model based on the result of the demand analysis conducted with 70 incumbent elementary school teachers and 120 third grade students. The developed program was applied to 24 third grade students for 36 classes in six days and a comparison was made through pre-post comparison tests with 24 students who were taught with a board game program for the same period of time. As a result, the unplugged education program which focuses on the algorithm execution time analysis is deemed to have positive effect on the computational thinking of the third grade students.

In this study, we analyzed the effects of data visualization education with using Python on the improvement of computing thinking ability of the 6th grade students of elementary school. Based on the results of the needs analysis of 60 elementary school teachers and 120 elementary school students, we developed the data visualization education program. In the developed educational program, 24 elementary school students were trained for 6 days and 36 hours in total. Thereafter, students were subjected to pre- and post-comparison tests. As a result of the analysis, it was found that the data visualization education with using Python is effective in improving the Computational cognition, Fluency, Originality, Elaboration of the 6th grade students in elementary school.

In this study, an unplugged education method which focuses on the data visualization training was applied to third grade students of an elementary school and analyzed its impact on enhancing their computational thinking. The analysis was conducted on 60 elementary school teachers and 124 third grade students and the unplugged education program based on the data visualization procedure was developed. The education program developed was carried out with 24 third grade students for 36 hours over six days. The effect of the program applied was analyzed through the pre-to-post comparison performed with perceptive strength test and creativity test in order to examine the enhancement in computational thinking. According to the analysis result, the unplugged education method which focuses on the data visualization training has significant effect on the 'computational perception' and 'creativity' of third grade students.

The purpose of this study is to develop a Python sorting algorithm training program based on execution time as an educational method for enhancing the logical thinking power of elementary students and then to verify the effect. The education program was developed based on the results of the pre-demand analysis conducted on 100 elementary school teachers. In order to verify the effectiveness of the developed educational program, I teached 25 students of the volunteer sample of the elementary school education donation program conducted at ${\bigcirc}{\bigcirc}$ University conducted 42 hours, 7 days. The results of the pre-test and post-test were analyzed using the 'Group Assessment of Logical Thinking(GALT)' developed by the Korea Educational Development Institute. The results showed that the Python sorting algorithm training centered on execution time was effective in improving the logical thinking ability of elementary school students.

In this paper, through a questionnaire to currently active actors, we sought to understand their understanding of American acting methods and whether there are any particularly effective or ineffective acting training methods among various method related to this. For this, pre-questionnaire was conducted to ask about their understanding of American action methods, and post-questionnaire was conducted to find effectiveness of American acting method and effect of individual method after performing simple acting training with four representative theories of American action methods According to the analysis, the actors surveyed were not familiar with the American acting method and want to systematic methods in acting training. All of the acting training through the American acting method were effective, especially Stella Adler's imagination was the most effective method. The least effective method was Sanford Meisner's repetition. The results of this study can be used as fundamental data for introduction and utilization of American acting method in domestic acting training.

The purpose of this study was to analyze the impact of mediator effect related to role-orientation of traditional newspaper editors in terms of role-cognition and role-orientation in aspects of real reportage attitude by classifying the newspaper editor's role-cognition with social stability, reform, check, on the other hand, role-orientation with reporter's intention, intention of actual fact, and reader's intention. The results were as follows: In terms of reporter's intention the research showed the fact that reporter's intentions was influenced by the role cognition of social stability and at the same time, it also made to reduce the attitude of real reportage. Compared with intention of actual fact and reader's intention, the intention of actual fact could be only influenced by the social stability, but it could not give any effectiveness to the attitude of real reportage, furthermore, the research showed the fact that reader's intention aroused some mediator effects which newspaper editor's role cognition gave rise to the attitude of real reportage much more strongly.
