The purposes of this study were to investigate the relationship between science achievement and student-related variables in the 2006 National Assessment of Educational Achievement (NAEA), the subjects of which included 3% of students within the entire population of the grades 6, 9 and 10. The results showed that the more they talk with parents, study by themselves, and read the books, the higher the students achieved in science. The science achievement was also significantly and positively related to self-regulated learning, adaptation to school life and attitude toward science. It is implied that the approach of stimulating internal motive such as interest, attitude toward science and human relations is more effective in resulting in the students' higher science achievement than focusing on external attitudes such as forcing good study habits.

The purpose of this study were to develop of courseware using scaffolding strategy and to investigate the effect of courseware instruction upon students' conceptual understanding and affective domain including effort and self-checking. 10th grade students in the experimental and control groups were selected from high school at Cheongwon-gun in Chungbuk, and taught about chemical reaction rate for 3 class hours. The students in the experimental group studied individually through courseware using scaffolding strategy and worksheet and teacher-centered expository lesson was used in the control group. Prior to the instructions, test specification for problem-solving assessment (TSPSA) was administered and the scores of the previous science achievement test were obtained. After the instructions, the posttest on conceptual understanding and TSPSA were administered. Results of this study revealed that the mean score of the experimental group in the conceptual understanding test was similar to that of the control group at statistically significant level. This result implies that the courseware using scaffolding strategy could be a tool of the individualized instruction. The experimental group improved significantly better in three components of the TSPSA such as effort, self-checking, and cognitive strategy. From this result, it is considered that learners' self regulation is improved by being taken over responsibility of learning. So, it is suggested that instruction using scaffolding strategy is needed in science class to improve self-leading learning ability.

This study aims to 1) verify the validity of the Science self-efficacy scale and 2) perform a latent mean analysis of the background variables about a pre-service teacher. The study uses pre-tests to analyze data from 187 pre-service teachers, which uses Tark's Science self-efficacy scale (2011). To identify the factor structure, exploratory factor analysis was performed. Based on the results of the pilot test, the expert group council revised the scale for the pre-service teachers to respond to the 3-factor structure. In the main test, 354 data were analyzed through a modified Science self-efficacy scale, and exploratory and confirmatory factor analyses were performed. The results of the study are as follows: First, in the pilot test, the pre-service teacher responded to a 3-factor instrument, but the validity of two items was examined further below. Second, the pre-service teachers responded to a 3-factor instrument on 29 items for the modified Science self-efficacy scale. The total reliability of the instrument was .886 and the reliability of each factor was analyzed as .882-.886. Finally, the latent mean analysis by gender showed that females have a higher self-regulation efficacy factor and males have a higher self-confidence factor (Cohen's d > .3). Furthermore, there is a significant difference in task difficulty preference and self-regulatory efficacy factor (Cohen's d > .8) between the college preparatory and science subject preference. This study provides important insights into and contributions to the accurate scientific self-efficacy diagnosis of pre-service teachers, as well as proposes a curriculum to improve the scientific self-efficacy of prospective teachers.

The purpose of this research is verifying the effects born by reading-based learning coaching programs on Korean language performance and the psychological variables of middle school students. A reading-based learning coaching program applied alongside a coaching model was developed and presented to first grade middle school students living in a local county-level city. The psychological variables were measured three times: prior to the program, immediately following the end of the program, and one month after the end of the program. Korean language performance was only measured twice: prior to the program and following the end of the program. Results revealed that compared to the control group, the experiment exhibited showed significant improvement in the scores of learning efficacy and self-regulation efficacy after the program. As well, these changes lasted for up to one month after the program. The future time perspective didn't show any significant interaction effects between time and group. The experimental group's performance in terms of Korean language was also significantly improved after completing the program. Based on these results, implications and limitations are discussed.

The purpose of this study was to examine the moderating effect of perceived parental empathy in the relationship between adolescent depression and eat problem. For this purpose, we conducted a hierarchical regression analysis for 246 middle and high school boys in the K region. As a result, the relationship between eating problem and depression was controlled by parental sympathy. As a result of analyzing the moderating effects of sub- factors of parental sympathy, in the case of the father, awareness of emotion, cold emotional reaction, and excessive emotional reaction showed moderating effects. And in mothers, awareness of emotion, perspective taking, cold emotional reaction, and excessive emotional reaction moderated the relationship between eating problem and depression. It is significant that this study confirmed that the empathy of parents perceived by adolescents is a control variable to mitigate the adverse effects of depression on eating problems.

The study aimed to investigate elementary school gifted students' hypothesis-generating ability and characteristics of hypotheses and to analyze the correlation between hypothesis-generating ability and meta-cognition. Nineteen students enrolled in a science gifted education center affiliated with a university in 2013 were selected as research subjects. An instrument of open ended items about hypothesis generating was developed and administered to students, and their meta-cognition as well as their preferred science teaching method were examined. Hypotheses generated by students were classified into two categories: scientific and non-scientific hypotheses, and then a closer analysis was conducted on characteristics of non-scientific hypotheses. It was found that 47% (18 out of 38 hypotheses) was scientific ones showing that elementary school gifted students in science in this study presented low level of ability in generating hypothesis. It was also found that non-scientific hypotheses frequently showed characteristics of uncertain in causality or impossible to verify relationships. Furthermore, differences in hypothesis-generating ability and characteristics of hypotheses were appeared in conditions whether inquiry questions and variable identification process were given or not. Students showed high abilities in hypothesis generating and variable identifying when inquiry questions and variable identification process were given. Compared to previous research results, students in the study showed high level of meta-cognition and tendency of utilizing monitoring strategy more than planning and regulating. In ill-structured conditions that students themselves find inquiry questions and identify variables, a significant (p<.05) correlation appeared between hypothesis generating ability and meta-cognition and a high level of correlation between planning and regulating strategies. It was also found that differences existed in hypothesis-generating ability and preferred science teaching methods between students with high level and those with low level of meta-cognition; and students with low level of meta cognition showed difficulties in generating hypothesis and identifying variables.

This study analyzed the factors influencing baby boomers' reemployment intentions. The extended Theory of Planned Behavior(TPB) as a research model used in this study. The extended TPB added outcome expectations and economic preparation as independent variables. Personal characteristics were set as a moderating variable and reemployment intention was set as a dependent variable. Based on the questionnaire survey of 250 baby boomers for the established research model, an empirical test was conducted through regression analysis. The results of empirical testing are as follows. Attitude, perceived behavioral control, and outcome expectations had a significant positive (+) effect on the baby boomer's reemployment intention. On the other hand, economic preparation had a significant negative (-) effect. Social norms have not been tested for significant influence relationships. Among the significant variables, economic preparation was found to have the greatest influence. The results of moderating effect of personal characteristics, both agreeableness and conscientiousness were found to play a role in moderating between attitudes and reemployment intention, between outcome expectations and reemployment intention. Based on these research results, academic and practical implications for the baby boomer's reemployment were presented.

As the demand for elderly care service has been on rise due to the increasing of the aging population, the role of visiting caregivers becomes increasingly important. In this context, this study aims to examine whether there are moderating effects of social support and self-efficacy on the relationship between resilience of visiting caregivers and their burnouts. The hierarchical regression analysis was used for statistical analysis. The findings from the study are as follow. First, resilience has a negative effect on burnout. As the resilience increases, the burnout decreases. Second, social support has moderating effects on the relationship between a resilience sub-variable(positivity) and burnout. Third, self-efficacy has a moderating effect on the relationship between a resilience sub-variable(self-regulation) and burnout. The findings of the study suggest that nursing facilities pay attention to psychological characteristics of visiting caregivers as well as their job characteristics in designing burnout prevention programs for them.
