This study explored students' subject interests and task difficulty recognition levels changed when they provided tasks with Keller's ARCS motivation design in PBL(Problem Based Learning) class. This study participant were 79 college students majoring in teaching profession. Experimental and comparative groups were formed for the study. Primary PBLs were conducted to measure prior levels of subject interest and task difficulty recognition. Secondary PBLs were performed to verify the effectiveness of the ARCS motivation design task. The experimental group performed the tasks that reflected the ARCS motivation design. Collected data were analyzed using ANCOVA. As a result, the experimental group had a higher level of subject interest and a lower level of task difficulty recognition.

The purpose of this study was to analyze the effect on the level of subject interest and interaction when supporting scaffolding considering learner characteristics in PBL. For the study, the participants were 86 college students. The research procedure was as follows. First, we divided the experimental group and the comparative group. A primary PBL was used to measure prior levels of subject interest and interaction. Secondary PBL was performed to verify treatment effect. In the second PBL, the experimental group received cognitive, metacognitive, and motivation scaffolding that reflected the learner's characteristics. The control group received random scaffolding. Subject interest and interaction were measured after the end of the second PBL. Collected data were analyzed using ANCOVA. As a result, the interest and interaction level of the experimental group was analyzed to be higher than that of the control group.

This study compared levels of mathematically talented students' statistical thinking with those of non-talented students in the noticing of statistical variability. t tests were conducted to test for statistically significant differences between mathematically gifted students and non-gifted students. Results for the t-test shows that there is no difference between the TE students' and NE students' noticing of variability in the measurement settings. Meanwhile, the t-test results also show that there is a difference between the TM students' and NM students' noticing of variability in the both measurement and chance settings. Table of frequencies of each level, however, shows that levels of mathematically gifted students' thinking were not distributed at the high levels but were overlapped with those of non-gifted students. These results are thought-provoking results in statistics instruction for mathematically talented students.

The purpose of this study was to compare the health behaviors of North Korean refugee women according to their health cognition level. The tools were selected through focus group interviews of researchers and respondents to carry out the purpose of the study while being as brief as possible, and to secure content validity by the expert group. Based on this, the health cognition level was divided into three stages and organized into groups, and health behavior was composed of nutrition, exercise, and sleep as three factors to help actual behavior change. For data analysis, one-way ANOVA was used to compare health behaviors according to each health cognition level, and the following conclusions were obtained. First, there was a significant difference in nutrition and sleep of health behavior according to the level of physical health awareness, but there was no significant difference in exercise. Second, there were significant differences in nutrition, exercise, and sleep of health behavior according to psychological health cognitive level. Third, there was a significant difference in nutrition and sleep of health behavior according to social health cognitive level, and there was no significant difference in exercise.

This study investigated the differential interactive effects of the combination of driving confidence and sensation-seeking on driving anger among different age groups, by using correlation analysis, a hierarchical regression and ANOVAs for the data gathered through the questionnaires administrated in a form of face-to-face interview. The results showed the followings. First, males tended to show higher level in driving anger than females. Second, whereas sensation-seeking was positively correlated with driving anger, age and driving experience were negatively correlated with driving anger, respectively. Third, although there was no significant relationship between driving confidence and driving anger among the drivers aged under 40 years, the drivers aged over 40 years showed higher level of driving anger as their driving confidence increased. Forth, level of sensation-seeking was found to be a strong predictor of driving anger in all age groups. Fifth, driving confidence and sensation-seeking appeared to affect the level of driving anger interactively among drivers aged under 40 years or over 65 years, resulting in higher driving anger only when both the levels of driving confidence and sensation-seeking were high. In contrast, driving confidence and sensation-seeking affected driving anger independently among the drivers aged 30-49 years. Implication and suggestion were discussed.
