This study investigated the influences of applying the Cognitive Conflict Process Model (the Procedural Teaching Model using Cognitive Conflict Strategy: Kwon, 1989) upon students' achievement and attitudes in a middle school science concept instruction. For the treatment group, science instruction to apply the Cognitive Conflict Process Model was used. For the control group, traditional instruction was used. Prior to instruction, students' pre-conceptions test and attitudes test related to the science were administered. After instruction, the above two tests and the regular examinations were measured. Also students' perceptions of their teacher's new teaching style was investigated by questionnaire. But, above all, the main purpose of this study was to investigate the principal accompanying matters of general application of the teaching model to science concept instruction rather than conceptual and attitudinal change. Therefore, this study identified necessary conditions of applying the teaching model to science instruction.

The purpose of this study is to understand the conflicts that occurred in the rural village's joint management project. This study examined the perception of conflicts among people working in agricultural related fields. A questionnaire survey was given to collected data from people who participated in nation-wide resrvice training course programs. The content of the questionnaire consisted of the factors of conflict in a rural village and the details recognized by general farmers. The data was collected from October 15 to 23, 2007. 206 samples were used for final analysis from a total of 240 samples. Frequency analysis and T-test between variables were conducted by SPSS 14.0. The results suggest that farmers have a negative perception of the business partnership. Proposal for business partnerships should be avoided because of the conflicts between partners. Accordingly, as farmers don't recognize that their joint project is a business partnership, the likehood of a conflict in the agricultural joint business operation and management is contained. Conflicts mainly exist between a village leader and villagers. The main reasons for conflicts are a lack of interest and lack of communal homogeneity, and lack of methodology to share the benefit of business. It will be necessary to understand the aspects of future conflicts in order to manage joint projects ill agricultural experience villages.

The types and the characteristics of students' responses to anomalous data in studying 'boiling point' were investigated, and the degree of cognitive conflict and conceptual change were compared by students' cognitive variables. Tests regarding field dependence-independence and logical thinking ability, a preconception test, and a test of responses to anomalous data were administered to 137 sixth graders. Among them, 90 students whose preconceptions were consistent with the presented initial theory were selected. After learning the scientific concept, students' conceptual change was examined. Six types of responses identified were as follows: Rejection, reinterpretation, exclusion, uncertainty, belief decrease, and theory change. The main responses were rejection (33%) and theory change (39%). The results of Mann-Whitney U test indicated students who were field independent and had higher logical thinking abilities felt more cognitive conflict and exhibited more conceptual change.

In this study, we investigated the role of a discrepant event from both cognitive and motivational perspectives in learning the concept of combustion. A preconception test, a test of response to a discrepant event, and a situational interest questionnaire were administered to 433 eighth graders. After learning the concept of combustion, the tests of attention, effort, and conceptual understanding were administered as post-tests. The reponses of 208 students who had been found to possess the target misconception were analyzed. The percentages of rejection and exclusion responses were relatively high compared to the previous studies about density concept, whereas a proportion of belief change was low. The results of the path analysis indicated that situational interest after presenting an alternative hypothesis had a direct effect and an indirect effect via attention and effort on conceptual understanding. Situational interest induced by a discrepant event directly influenced cognitive conflict after presenting an alternative hypothesis.

This study was to investigate the elementary students' preconception on the brightness of electric bulb and degree of consistency on their preconceptions. Participants were 160 students of fifth graders in Seoul area. They had already teamed about the brightness of series circuit and parallel circuit of batteries. After they solved six problems in the same context, we provided them a pair of circuit which was an anomalous situation. And then they conducted CCLT (Cognitive Conflict Level Test). Elementary school students showed various preconceptions when they explained the light of bulb of two Simple electric Circuits. Many Students Consistently Showed the Scientific misconceptions like 'the light of bulb of two simple electric circuits was that the more batteries and the fewer bulbs were brighter.' The level of consistency that students presented scientific misconceptions was grouped all of four, such as 'high, middle, low, and nothing.' Therefore the higher scientific achievement they have, the higher consistency they have. As the students had high consistency level, they revealed high cognitive conflict level significantly. This high consistency will help them to change their preconception on the brightness of electric bulb and their cognitive conflict.

Farm village business performance may be influenced by village leader's leadership and conflict management between villagers, so the objective of this study is to analyze the relationships among farm village leader's leadership, conflict management between villagers and farm village business performance. The questionnaire was performed for 376 villagers in Jeollabuk-do Province. The collected data was analyzed by structural equation model and Sobel test. The result shows that farm village leader's leadership such as human-relationship ability, management ability, communication skills, and industrial knowledge ability have statistically significant positive effects on the conflict management between villagers. The conflict management between villagers also showed a statistically significant positive effects on the social and economic performance. The farm village leader's leadership such as human-relationship ability, sensibility·awareness ability, management ability, communication skills, industrial knowledge ability showed no statistically significant effects on the social and economic performance. But, they showed a statistically significant effects on the farm village business performance in indirect manner with the mediating effect of the conflict management between villagers. It is worthwhile that in this study, the effect of village leader's leadership on the conflict management between villagers and farm village business performance was verified, and then, it is meaningful to present the role and importance of farm village leader's leadership.

The purpose of this study was to investigate high school students' ideas related with dinosaur extinction, to classify students' responses types with alternative hypotheses of inconsistent with their ideas, and then to examine their cognitive conflict levels and the degree of ideas change. To investigate students' ideas, we analyzed responses 98 eleventh graders of a high school in Anyang area. The results of this study were as follows: First, most of the students responded a large scale asteroid impact with the cause of dinosaur extinction, and rest of them responded changed Earth's climate accompanying tectonic activity, extreme volcanic activity, shortage of food, disease(virus) and decrease of their habitat. Also, they thought that dinosaur was exterminated not by just one reason but by several complex reasons. Second, the students' responses of alternative hypotheses were classified into six types: rejection, reinterpretation, uncertainty, belief decrease, partial theory change, and theory change. Third, except rejection and reinterpretation types, other four types were arousing of cognitive conflict and the percentage of the students who felt cognitive conflict was 62.3% and that of the students who took the theory change was just 6.1 %.

The purpose of this study is to compare and analyze secondary school student's brain activity on assimilation, conflict, and accommodation processes of self-regulation. The self-regulation task was presented a biological phylogenetic task, and the brain activity was measured and analyzed with fNIRS. As a result, a significant activation was found in the left DLPFC, OFC, and FP regions in the conflict process compared to the assimilation process, and a significant activation was found in DLPFC and VLPFC in the accommodation process. As the age increase, the DLPFC also increases in the conflict process and VLPFC increases in the assimilation process. In addition, comparing conflict and accommodation process, the 7th grade students show a significant brain activity in the right VLPFC, the 9th grade students show significant brain activity in the left FP and DLPFC areas in the accommodation process. However, the 11th grade students did not show any significant brain activity at this process. These results presumably show that the neurological research method could be applied to educational research in cognitive activity and classroom instructional situation.

This study was conducted to provide basic data to understand the interaction patterns of dual-income parents' happiness by confirming the effect of work-family reconciliation recognized by dual-income parents on parental happiness. The subjects of the study were 630 pairs of dual-income parents out of 1462 pairs of parents who participated in both the main questionnaire and in the mother and father questionnaires in the 8th Panel Study on Korean Children (2015), and they were analyzed based on the Actor and Partner Interdependence Model (APIM). The results of this study show that the gain and strain of parents' work-family reconciliation had an actor effect on parents' happiness, and the gain and strain of father work-family reconciliation had a partner effect on mother's happiness. This study was meaningful in that it provides basic data on intervention and program development that could increase the happiness of dual-income parents. In order to increase the happiness of dual-income parents, it is necessary to provide intervention and education. In the future, we propose a study to confirm changes in influencing factors of parents' happiness according to time.
