The purpose of this study was to investigate the causal relationship among job stress, teaching efficacy belief, and organizational commitment for early childhood teachers. Besides, the current study examined the mediating effect of teaching efficacy belief on the relationship between job stress and organizational commitment. The data were gathered through the questionnaires from 500 kindergarten and nursery teachers who are located in D metropolitan city. Among them, the total of 426 subjects were used for analysis from recovered 442. The results indicated that job stress was negatively correlated with teaching efficacy belief and organizational commitment for early childhood teachers. Teaching efficacy belief significantly had a positive relation with organizational commitment. Moreover, teaching efficacy belief turned out to have a partial mediating effect on the relationship between job stress and organizational commitment. This study has its significance in that it looked at the job stress as a predictor variable to explain the organizational commitment, the positive viewpoint by turning away from the early childhood teachers' burnout, and provided the potential for the environmental intervention by confirming the mediating effect of teaching efficacy belief.

The benefits of teaching learning materials to others have been shown on learning achievement. Anxiety is one of the obstacles in learning and it has been shown that math anxiety is strongly associated with math achievement. Thus, the aim of this study was to investigate whether teaching others benefits math anxiety when university students learn statistics. 59 students who enrolled in statistics class participated and 30 students performed group assignment of teaching peer in a group and 29 students did not. Other than group assignments, the instructor, lectures, assignment of solving the problems, and exams were all the same. The results showed that the math anxiety of students who did group assignments of teaching was decreased at the end the semester. Increased math anxiety yielded negative attitudes toward learning statistics, resulting in poor learning performance. Furthermore, the relationship between math anxiety and the attitudes toward leaning statistics was moderated by teaching others. The results suggest that teaching others has an effect on reducing math anxiety and thus, possibly yield persistent learning gains.

This study examined how pre-service elementary teachers' perceptions regarding the learning environment (learning focus/ability-meritocracy/cooperative climate) and achievement goals (mastery/performance-approach/performance-avoidance) in science education courses jointly contributed to their science teaching efficacy beliefs (personal science teaching efficacy belief/science teaching outcome expectancy). A path analysis supported a causal model in which the perception of the learning focus influenced the mastery goal, which in turn influenced the personal science teaching efficacy belief and science teaching outcome expectancy. The perception of learning focus also had a direct effect on science teaching outcome expectancy. The perception of ability-meritocracy influenced personal science teaching efficacy belief via the performance-approach (positively) or, conversely, the performance-avoidance goal (negatively). No link .was deduced from the perception of cooperative climate. The educational implications of these findings were also discussed.

Objective: This study investigated how early childhood teachers'creativity and teaching flow was associated with their job satisfaction and examined the mediating effect of teaching flow. Methods: Participants were 222 early childhood teachers in Seoul. Descriptive statistics for all study variables were computed. To examine the hypothesized model and the alternative model structural equation modeling (SEM) was used. Results: The results revealed that early childhood teachers'creativity and teaching flow were positively associated with their job satisfaction. Early childhood teachers'creativity had an influence on their teaching flow, however, it didn't have a direct affect on their job satisfaction. Early childhood teachers' teaching flow had an affect on their job satisfaction. Additionally, early childhood teachers'teaching flow mediated the effects of teachers' creativity on their job satisfaction. Conclusion/Implications: In conclusion, early childhood teachers'teaching flow was a key predictor in the relationship between teachers' creativity and job satisfaction. This study provides guidelines for interventions aimed at increasing the job satisfaction of early childhood teachers.

This study examines the effect of using interactive electronic models to teach mathematical concepts on students' achievement in the linear algebra course at university. The field sample consisted of 200 students divided into two equal groups, an experimental group of 100 students and a control group of 100 students. The researcher used an achievement test in some mathematical concepts related to linear algebra. The results of the study showed that there were statistically significant differences (0.05) between the average achievement scores of the experimental and control groups in the post application of the achievement test, in favor of the experimental group. The size of the influence of the independent factor on the results of the study, which is "interactive electronic forms", on the dependent factor, which is the students' academic achievement in the prepared test, had a very large effect. Also, the results of the study showed that there were statistically significant differences (0.05) between the mean scores of the experimental group in the pre and post applications of the achievement test, in favor of the post application. The researcher recommended the use of interactive electronic models in teaching mathematical concepts at the university level and diversifying the strategies of teaching mathematics, using technology to attract learners and raise their academic achievement.
