  • This study included eleven elementary pre-service teachers who participated in the first and second teaching practices held by J Education College in 2015. After the pre-service teachers were encouraged to self-reflect on their mathematics teaching using a reflective survey sheet of mathematics teaching expertise, their uses of mathematics teaching expertise were analyzed according to the times of their mathematics practice instructions. The results are as follows: First, as the frequency of their mathematics teaching increased, the pre-service teachers' uses of mathematics teaching expertise increased, especially greatly with seven of them. However, the number of subcategories where the teachers' uses of mathematics teaching expertise increased was different from at least two to seven depending on the teachers. Second, the pre-service teachers who performed mathematics teaching practices four times used more of mathematics teaching expertise than those who did two times or three times. Third, some pre-service teachers who taught two or three times never reached 90% of the total score of any subcategory, even in the subcategory where they showed increase in their uses of mathematics teaching expertise. Fourth, the subcategory of 'reflection before class - teaching perspective - understanding of mathematics subject knowledge' was analyzed as the most difficult one for the study participants, and the reason is, they think, that there are not enough materials on the historical back grounds of mathematical concepts.

  • The purpose of this study is to examine the relationship between self-leadership of teachers who conduct free-selection activities in kindergartens. In addition, we analyze the mediating effect of teacher self-efficacy. This study was conducted using data gathered through a survey conducted on 325 kindergarten teachers in Seoul and Gyeonggi-do areas from September 17 to 28, 2018. To analyze the data, the author used SPSS Statistics 22.0 and AMOS 20.0 programs to conduct reliability analysis, confirmatory factor analysis, correlation analysis, and structural equation modeling. The result of the verification of the hypothesis showed that self-leadership of kindergarten teachers who engaged in free-selection activities positively influenced self-efficacy. Self-leadership of teachers who employed free-selection activities had a positive effect on the expertise of teachers as well. Also, self-efficacy of kindergarten teachers positively affected expertise of these teachers. In addition, the self-leadership of kindergarten teachers mediated self-efficacy, so that the indirect effect on teacher expertise was statistically significant. Also, the direct effect of self-leadership on expertise of teachers was significant, which showed that the self-efficacy of the kindergarten teachers indirectly mediated the relationship between self-leadership and expertise of the teachers. This study showed that to enhance expertise of kindergarten teachers, this requires enhancing self-leadership of teachers. Also, in order to enhance the level of self-efficacy of teachers, necessary knowledge and skills that can enhance self-efficacy of these teachers in their working environment should be provided. In addition, someone who can play the role of active facilitator or helper is needed in order to enhance expertise of these teachers.

The 400 valid samples were applied to the data analysis. The study used SPSS 21.0 for processing the gathered data via a frequency analysis, a reliability analysis and a correlation analysis and in order to verify the hypotheses, the study applied AMOS 21.0 and conducted a confirmatory factor analysis and a structure equation model analysis. Findings that the study had extracted are summarized as follows. First, the study confirmed that the scuba diving instructors' expertise has a positive effect on the instructor reliability. Second, the scuba diving instructors' expertise was reported to positively influence the instruction efficiency. Third, the results revealed that the scuba diving club members' reliability in the instructors has a positive influence on the instruction efficiency.

  • The purpose of this research was to identify expertise in ait traffic control by using cognitive skill analysis for novices and experts in routine and non-routine situations. The result of study was to understand expertise in air traffic control tasks in terms of what cognitive processes are responsible for the expert's high performance levels. The problem solving task was difficult for novices, but performed relatively automatically by experts in a routine situation. The difficulty could indicate the presence of controlled processing. Rather than rules and strategies, novices focused more on environmental factors, which merely increase cognitive load. In a non-routine situation, novices showed that they did not categorize the information consistently and alternative resources were not available for them. Experts, however, performed automatically a task by arranging and organizing information related to problem solving components in contexts without regard to a routine and non-routine situation. Especially experts developed a stable representation and directed alternative resources for air traffic flow and efficiency. Based on the results, cognitive processes of experts could be useful to understand expert performance and analyze the learning process, which imply the necessity of developing expertise systematically.

  • The objective of this paper is to study if the EEG spectral relative power would be a reasonable measure of expertise level. EEG electrodes were placed on the locations of Fp1, Fp2, F3, F4, T3, T4, O1, O2 while 5 subjects were playing 4 kinds of game on PC. EEG spectral relative power was significantly related with expertise level on the locations of Fp1, T3, T4, O1, O2. And the results showed that the $\theta$ and $\alpha$ activities were decreased, while $\beta$ and $\gamma$ activities were increased. The results indicated that the EEG spectral relative power would be applicable as a quantitative measure of expertise level.
