This study tried to analyze the case of character education class using reading for pre-primary early childhood teachers. To this end, the criteria for character education were established based on literature research, and a list of books appropriate for it was selected, and then applied to practice. The goal of character education class using reading for pre-school teachers is to cultivate the character that an early childhood teacher should have and to develop the ability to apply character education program through reading to young children. This study selected books based on the contents of personality virtues after taking a course on the concept and theory of personality contents for college students who are taking the 'personality and emotional reading' course in their major. Therefore, this study is meaningful in that it presents contents that can be practiced in connection with the family as a personality education program that can be applied not only to pre-primary teachers, but also to early childhood teachers and young children.

In order to improve the SW convergence capabilities of university undergraduate students, methods to evaluate undergraduate students' code design capabilities should be researched along with the development of related courses. In previous studies, there were qualitative evaluation methods and quantitative relative evaluation methods for code results. In the quantitative relative evaluation method, the number of problem decomposition depth, number of function reuses, and number of functions were measured and evaluated. In this study, an evaluation method that was not presented in previous studies was proposed using the problem of presenting the number of input and output information types when designing code. The evaluation problems proposed in this paper applied up to three types of input information and three types of output information. Through this, five code design evaluation questions were presented and a method to quantitatively calculate code design scores was proposed. Codes from 100 student respondents were collected and analyzed through courses that applied the proposed evaluation method. Through result analysis, the number of problem decomposition depths was proportional to the number of types of input information, the number of function reuses was proportional to the number of types of output information, and the number of functions showed a correlation that was proportional to the total number of types of input and output information. Lastly, by analyzing the distribution of evaluation scores of 100 respondents, we demonstrated that the code design evaluation method according to the five input/output information condition evaluation problems is effective.

There can be two different approaches to introducing Abstract Algebra to undergraduate students: One is to introduce group concept prior to ring concept, and the other is to do the other way around. Although the former is almost conventional, it is worth while to take the latter into consideration in the viewpoint that students are already familiar to rings of integers and polynomials. In this paper, we investigated 16 most commonly used Abstract Algebra undergraduate textbooks and found that 5 of them introduce ring theory prior to group theory while the rest do the other way around. In addition, we interviewed several undergraduate students who already have taken an Abstract Algebra course to look into which approach they prefer. Then we compare pros and cons of two approaches on the basis of the results of the interview and the historico-genetic principle of teaching and learning in Abstract Algebra and suggest that it certainly be one of alternatives to introduce ring theory before group theory in its standpoint.

The purpose of this study was to investigate the effect of the 'Chemistry and Experiment' course employing the Small-Scale Chemistry(SSC) experiment on the 30 pre-service elementary teachers' attitude toward laboratory work and their science teaching efficacy. This study also examined the perception of the pre-service elementary teachers about the SSC experiment. In the result, there were found significant interactions between the treatment and prior level in attitude toward laboratory work. The attitude toward laboratory work of low-level pre-service teachers was improved while that of high-level pre-service teachers remained unchanged. However, there was no significant change in their beliefs regarding science teaching efficacy. Through the analysis of questionnaire, it was also found that they had positive perceptions about the SSC experiment, and most of them as pre-service teachers found the SSC experiment helpful to teach chemistry experiments.

In this research, we investigated the effects of mathematics education in using Socrates , method in a course of mathematics education in teacher's college. And we proposed some suggestions for education of future mathematics teachers. This study was conducted with 44 university students(third grade) who entered the department of mathematics education (future mathematics teachers) in 2005. We took a course in curriculum that was required for the future mathematics teachers in my department. In this course, we began with the reading the famous dialogue between Socrates and Meno's slave. And we analysed Socrates' questioning of Meno's slave and tried to understand what this dialogue is implicating in mathematics education. All the participants in this course was divided 11 groups. Each group designed a school mathematics class plan using Socrates' method and practiced their teaching plan by a performance(students' announcements). Through the analysis of research data. Five effects of mathematics education in using Socrates' method for future mathematics teachers were induced. Therefore, we suggest that future mathematics teacher need to have many opportunity to design and practice a mathematics teaching plan by using mathematics teaching-learning methods taught in their course.

Teaching ICT skills in extracurricular activity classes of commercial high school helps to bridge the digital divide of the students at the minimum cost, and gives them a chance of getting ICT-related licenses. The purpose of this study is to identify the determinants of satisfaction and planned behavior toward computer classes, offered as extracurricular activities in commercial high schools. A survey methodology was used to investigate a proposed model of influence, and regression analysis was used to analyze the results. The hypothesized model was largely supported by this analysis, and the overall results indicate that the intention to participate in the class is mostly influenced by the expected social effect, individual impact and playfulness from the class. In addition, it was found that the learning environment influences the level of playfulness and social effect, and that the contents quality has some impact on the level of the ease of study and playfulness. Useful suggestions for promoting computer classes as extracurricular activities in commercial high schools are also provided.
