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.

As organizations have come to be more complex and diverse, management has come to spend an increasing proportion of its time and efforts in handling organization conflict. Moreover, organizational conflict problems are often not recognized until the balance of interests is destroyed or a radical organizational change such as BPR takes place. Once an organizational conflict arises, however, it reduces corporate synergy seriously, leading to organizational ineffectiveness. Therefore, it is important to identify the cause of organizational conflict in advance and resolve it based on the proper diagnosis as early as possible lest it should undermine the organizational effectiveness. We propose a method that facilitates diagnosing potential organizational conflict and determining appropriate strategy to the conflict, based on the analysis of cognitive maps. To support the application of the method in the real world context, a computerized tool is introduced. The working procedures of the method and the features of the tool are illustrated with their application to the real case of the cable TV home shopping company.

Based on conceptual change theory, cognitive conflict is known as an important factor for conceptual change even though there are still questions about its positive and negative effects on science learning. However there are little research which propose types of meaningful(constructive) cognitive conflict in learning science. The purpose of this study is to find out how are the anxiety types of cognitive conflict to which high school students respond in the action-reaction task, and to reveal what's the characteristic of the explanatory hypothesis according to the anxiety types. The result of this study indicated that first, the characteristics of the anxiety types of the cognitive conflict were classified as eight types. Especially the students who belong to the types of conviction of logical misconception and reasonable modification suggested explanatory hypothesis close to physical nature. On the other hand, the students who showed other types of anxiety except the two types of anxiety suggested temporary supported hypothesis or simple explanatory hypothesis based on students' observation and intuition. Finally we discussed the importance and the implication of the types of anxiety in applying the cognitive conflict strategy to science instruction.

In this study, the relationships among students' cognitive/affective variables, cognitive conflict induced by anomalous data, and conceptual change were investigated. Tests regarding background knowledge, field dependence-independence, learning strategy, logical thinking ability, goal orientation, self-efficacy on prior concept and ability, and control belief were administered. Tests of prior conceptions, responses to anomalous data, conception, and retention of conception were also administered. There were no significant correlations of cognitive conflict induced by anomalous data with students' cognitive and affective variables. However, prior knowledge on molecular motion, field dependence-independence, and learning strategy were significantly correlated with students' conception and retention of conception. Logical thinking ability was also correlated with their conception. Multiple regression analysis indicated that learning strategy significantly predicted students' conception and retention of conception. For the affective variables, self-efficacy on ability was significantly correlated with students' conception and retention of conception, and goal orientation was correlated with their conception. Self-efficacy on ability was a significant predictor on students' conception and retention of conception, and goal orientation on their conception.

This study examined the influences of cognitive conflict and anxiety induced by a discrepant event and an alternative hypothesis, attention, and effort on conceptual change. Two hundred three students having misconceptions about density were selected from 462 seventh graders based on the results of a preconception test. Tests of cognitive responses and anxiety to a discrepant event were administered before and after presenting an alternative hypothesis. Computer-assisted instruction (CAI) was then provided to students as a conceptual change intervention. Tests assessing attention and effort allocated to the CAI, and conceptual understanding were administered as posttests. Cognitive conflict induced by a discrepant event was found to increase after presenting an alternative hypothesis. Pre-cognitive conflict induced by only a discrepant event exerted a direct effect on post-cognitive conflict induced by a discrepant event and an alternative hypothesis. Post-cognitive conflict had a direct effect on conceptual change. Pre-anxiety decreased after presenting an alternative hypothesis. Pre-anxiety influenced post-anxiety, and this influenced on conceptual change via effort negatively. Attention had a direct effect as well as an indirect effect on conceptual change via effort. These results suggest that the strategy presenting both a discrepant event and an alternative hypothesis to students in concept learning could facilitate conceptual change by inducing more cognitive conflict or active participation of students through the decrease of anxiety than that presenting a discrepant event only.

In this study, students' responses to anomalous data in studying ‘density' were analyzed, and the relationships among trait/state self-regulation strategies, the degree of cognitive conflict, and conceptual change were examined. A trait self-regulation strategy test, a preconception test, and a test of response to anomalous data were administered to 352 eighth graders. Among them, 146 students whose preconceptions were consistent with the presented initial theory were selected. After they had read a scientific explanation, a state self-regulation test and a researcher-made conception test were administerd. There were no significant correlations among the subcategory scores of trait/state self-regulation strategies and the degree of cognitive conflict. The scores of the conception test were significantly correlated with those of trait planning, trait effort, state planning, state self-monitoring, and state effort. State effort was only a significant predictor on students' conceptual change.

Study courses using cognitive conflict strategy about geological stratum were performed on the 6th grade elementary students and their conceptual changes were investigated. Some misconceptions about geological stratum that the students have are as follows: (1) stratum was formed due to volcanic eruption, (2) gneiss composes the geological stratum, (3) folds in the stratum were formed due to vertical pressure from the top. The classes had positive effects on the changes of some the misconceptions: (1) the places where the stratum is filmed, (2) the kind of rock in the stratum, and (3) the reason for folding. However, there were no significant changes in the following items: (1) the reason that every layer consists of different sizes of grains. It shows that some misconceptions can be changed easily by cognitive conflict strategy, while others can not. We checked the students who didn't change their misconceptions after the test. These students have very strong misconceptions that most of the natural phenomena on the earth's surface are due to the internal heat pressure, and volcanic activity. Another affecting the students' misconceptions are the role of teachers in class and mass media, such as TV.

This study examined 8th-graders' conceptions of force on a simple pendulum and investigated cognitive conflict and conceptual change through kinesthetic experience in swing. Participants of this study were guided to anticipate the direction of total force acting on a pendulum at three critical positions and observed it through swing experience. Having completed this, students read an article explaining the results they observed. Most of them considered gravity, tension, and motion-force to be the real forces acting on a pendulum in pre-test. Though they were interested in the activity and conceded their expectations to be different from observed results, the degrees of their cognitive conflict were not significantly high. In summation, 'interest' was the highest and 'anxiety' was the lowest. Most of the students memorized the direction of forces on a swing, but few could explain the reason behind the occurrence in an immediate post-test and delayed post-test.

In this study, we investigated the influences of the epistemological beliefs on the conceptual change processes in respects of cognitive conflict, situational interest, attention and state learning strategies. After administering epistemological belief questionnaire as a pretest, 218 seventh graders possessing misconceptions about density were selected from the results of a preconception test. The questionnaires of responses to a discrepant event and situational interest were administered. After learning with a CAI program, attention test, state learning strategy test and conception test were also administered as post-tests. Analysis of the results revealed that fixed ability, quick learning and certain knowledge, which are epistemological factors, were highly related, but only certain knowledge exerted a direct effect on conceptual understanding negatively. It also had positive effects on attention directly as well as via situational interest, and thus increased conceptual understanding, even if the effects were relatively smaller than the direct effect. However, epistemological beliefs had little influence on conceptual understanding through cognitive conflict and/or state learning strategies.

Purpose The purpose of this study is to investigate cognitive mechanism of goal relations (Single-goal vs. Multiple-goals) and to-do list (Packing vs. Unpacking) and also verify the role of self-efficacy in the perspective of motivation belief. The perspective of cognitive mechanism is related to the effects of how the relations of multitasking environments affects to facilitating relation or conflicting relations. In pursuit of a single goal, judgement of task importance can be facilitated by unpacking effect due to relations of strongly associated project components including to-do list. On the other hands, in pursuit of multiple goals, judgement of task importance can be conflicted due to mutually exclusive relations of multiple goals. Additionally, the cognitive mechanism can be regulated from the role of self-efficacy, which contributes to motivation belief on how much a person is confident in achieving given tasks. In the end this research is to identify self-efficacy as boundary condition in inhibiting the effects of facilitation and conflict. Design/methodology/approach This study conducted Two-way ANOVA (Packing/ Unpacking * Single-goal/ Multiple-goals) to explore the effects of cognitive mechanism on task importance. After that we performed Three-way ANOVA, 2 (To-do list: Packing/ Unpacking) * 2 (Goal relation: Single-goal/ Multiple-goals) * 2 (Self-efficacy: Low self-efficacy/ High self-efficacy) to verify the role of self-efficacy between goal relations and to-do list. Findings In the cognitive mechanism, the task importance is not significantly different between in packed and in unpacked condition in pursuit of a single goal. But multitasking with multiple goals causes goal conflict, which means packed condition indicates significantly higher task importance than unpacked condition. Additionally, for a group with low self-efficacy unpacking leads to conflicting relation, which implies that packed condition is more efficient strategy than packed condition. On the other hands, in pursuit of mulitple goals, either packing or unpacking has no distinctive effects on task importance. However, participants with high self-efficacy are no longer affected by facilitating relation and conflicting relation as well in pursuit of either a single goal or multiple goals as well.
