In this article, we introduce an example about 'computers and mathematics education' and discuss its educational meaning. First, we survey two microworlds of Logo and DGS, which are two different representation systems for geometric phenomena. And we propose needs of connecting two microworlds with common perspective. And we suggest a mediation model that connects two representations in a microworld. Using this mediation model(Circle model), we construct a circle, a ellipse, and a cardioid with two different representations. It is important that the mediation model makes it possible that we translate descriptions from one representation into the other, and guess perimeters of planar curves. We also discuss roles and mathematical implications of this mediation model by error case in calculating perimeters of ellipses.

This research investigated if the embodied symbol using a turtle metaphor in a microworld environment works as a cognitive tool to mediate the learning of combinatorics. It was found that students were able to not only count the number of cases systematically by using the embodied symbols in a situated problem regarding Permutation and Combination, but also find the rules and infer a concept of Combination through the activities manipulating the symbols. Therefore, we concluded that the embodied symbol, as a bridge that connects learners' concrete experiences with abstract mathematical concepts, can be applied to introduction of various mathematical concepts as well as a combinatorics concept.

This study examines the effects of teacher's emotional intelligence on teacher-child interaction through the sequential mediation effects of efficacy belief about play and professional recognition. Participants were 268 teachers working at kindergartens in Gyeonggi area. Data were analyzed by descriptive statistic, Pearson's product-moment correlation, and the structural equation model using the SPSS 21.0 and Mplus 6.12 program. The main findings of this study are as follows: First, in regards to the relationship between emotional intelligence and teacher-child interaction, a single mediation effect of efficacy belief about play is significant. But there is no significant mediation effect of the professional recognition. Second, in regards to the pathway from emotional intelligence to teacher-child interaction, the professional recognition precedent mediation model is statistically significant, but efficacy belief about the play precedent mediation model is not significant. Based on the results, a concluding discussion was made regarding methods toward enhancing interaction between teacher and child.

This study aimed to identify the causal relationships among self-regulated learning strategy, problem solving efficacy, task value and learning outcome, and mediation effect of self-regulated learning strategy in engineering capstone design course. The data were collected from 363 university students who enrolled in capstone design courses and analyzed using structural equation modeling method. The results were: first, problem-solving efficacy and task value exerted significant effects on self-regulated learning strategy. Second, self-regulated learning strategy exerted significant effects on learning outcome, but problem-solving efficacy and task value did not. Third, problem-solving efficacy and task value showed significant indirect effects on learning outcome, which confirmed that self-regulated learning strategy fully mediated between two exogenous variables and learning outcome.

This study examined the association among practical teaching competence (PTC) and teaching efficacy (TE), and explored the mediation effects of theoretical teaching competence (TTC) between the PTC and TE of Practical Arts (Technology and Home Economics Education) teachers. Data were collected from the 301 survey responses completed by elementary, middle, and high school teachers. All teachers showed high levels of PTC, TTC, and TE. Elementary school teachers perceived higher PTC than middle and high school teachers. PTC, TTC, TE showed significant effect in regards to teacher's age and teaching career. Using multiple regression analysis, this study found that TTC fully mediated PTC and TE of elementary school teachers. For middle and high school teachers, there was a partial mediation effect of TTC in the relationship between PTC and TE. This study suggests that teacher education programs should develop a program that can enhance teaching efficacy by cultivating TTC and support teachers who want to strengthen competence, and more practical opportunities to practice teaching.

In this paper, the effect of daily creativity of engineering students on problem-solving ability is addressed through the dual mediating effect of teamwork competency and self-directed learning ability. To this end, a regression-based statistical mediation analysis has been performed on the dual mediation model in which daily creativity and problem solving ability were treated as independent and dependent variables respectively, and teamwork competence and self-directed learning ability were included as mediation variables. The analysis result confirmed that the daily creativity has direct effect on the problem-solving ability, as well as indirect effects through teamwork competence and self-directed learning ability. In particular, the serial mediating effect of teamwork competency and self-directed learning ability was also confirmed to be statistically significant in the relationship between daily creativity and problem-solving ability. This verifies that problem-solving ability can be improved not only directly by improving daily creativity but also indirectly by improving teamwork competence and self-directed learning ability. In addition, teamwork competency showed greater indirect effect on problem-solving ability than self-directed learning ability, so increasing teamwork competency has a more significant effect on improving problem-solving ability than increasing self-directed learning ability. Therefore, in order to develop better problem-solving ability, it is necessary to identify and improve the learners' teamwork competency first and to strive to create an environment where learners can solve problems based on mutual trust with their teammates.

Objective: The purpose of this study was to identify the mediation effect of value of children in the relationship between maternal parenting stress and ideal number of children and to verify whether perception of the adequacy of national public childcare facilities moderates this mediation relationship. Methods: For the analysis, the 6th year results (2013) from the Panel Study on Korean Children by the Korean Institute of Child Care and Education were used. The main subjects of the study were 1,611 mothers with children aged 60 - 66 months. Results: First, there was a partial mediation effect of mother's parenting stress influencing the ideal number of children through the value of children. Second, the enhancing effect of the perception of the adequacy of national public childcare facilities moderating the value of children and ideal number of children was verified. Third, perception of the adequacy of national public childcare facilities had enforcing effects moderating the value of children and ideal number of children and mediation effects moderating the influence of maternal parenting stress on ideal number of children through the value of children. Conclusion: Based on the results, it was confirmed that the expansion of national public childcare facilities is a factor strengthening the maternal intention of birth.

Objective: This study aimed to examine the sequential mediating effects of children's perceived maternal acceptance and peer acceptance in the relationship between maternal warmth and first grade children's school adjustment. Methods: Participants in this study were 979 seven-year-old children(498 boys, 481 girls) recruited for the Korea Child Panel Study. Data were analyzed by analyzing descriptive statistics, correlations, and significance of serial mediation pathways using SPSS 18.0 and PROCESS Macro 3.4. Results: Maternal warmth at age five effected perception of maternal acceptance at age six. Perceived maternal acceptance at age six effected perceived peer acceptance at age six. Perceived peer acceptance at age six effected school adjustment at age seven. Lastly, perceived maternal acceptance and peer acceptance at age six had a serial mediation effect between maternal warmth at age five and school adjustment at age seven. Conclusion/Implications: Perceived social acceptance during preschool years should be emphasized in order to promote school adjustment for first grade children. Parent education for promoting better parent child relationships should be considered and teachers should encourage peer play interaction to help children perceive acceptance from their peers.

The present study examined the relationship between parental academic achievement pressure and self-efficacy mediated by student's achievement goal orientation among elementary school students. The 638 participants were fifth graders living in a metropolitan area. Analyses revealed that children who were high both in performance-goal and mastery-goal orientation reported highest perceived parental academic achievement pressure and self-efficacy. Performance-goal orientation played a mediation role in the relationship between parental academic achievement pressure and self-efficacy, while mastery-goal orientation did not. The limitations of the present study and suggestions for future research were discussed.
