  • The purpose of this study was to investigate the relation between the levels of cognitive conflict and students' conceptual change. In this study, 30 Korean high school students were selected from 450 10th graders by examining the pretest results. Two different strategies were used to induce cognitive conflicts in students, an anomalous or conflict situations; demonstrations and logical arguments against students' preconception. After arousing the students' cognitive conflict, the level of cognitive conflict was rated. Pretest, post-test and delayed post-test were administered to check the conceptual change. The tests consisted of 5 items in mechanics and electricity, respectively. Therefore, the demonstration method showed effective conceptual change, more than the logical argument method did. Students changed their conceptions more easily and frequently in the area of mechanics than in electricity. Students who showed higher levels of cognitive conflict indicated more positive conceptual change than those who showed lower conflict levels. 59 cases (56%) out of 105 who experienced high levels of cognitive conflict were changed into scientific conceptions one month later; however only 16 cases (35%) out of 46 who experienced low levels of cognitive conflict changed into scientific conceptions. Students who experienced higher levels of cognitive conflict showed higher rates of conceptual change. It could be concluded that designing instruction to induce cognitive conflict is a useful strategy to promote conceptual change.

  • The purpose of this study is to investigate the relationships between cognitive conflict and students' causal attributions and to find out what kinds of attributions affect successful resolution of cognitive conflict in learning physics. Twenty-nine college students who attended a base general physics course took an attribution test and a conceptual pretest related to action and reaction concept. Of these, twenty students who revealed alternative conceptions were selected. They were confronted with a discrepant demonstration and took part in the cognitive conflict level test, a posttest, and delayed posttest. Those students who experienced high levels of cognitive conflict were selected and interviewed to find out what kinds of attributions affect resolving the conflict. When confronted with the discrepant event, the students who attributed success outcomes to "effort" experienced higher levels of cognitive conflict than those to "task difficulty." However, those students who revealed high levels of cognitive conflict and attributed success outcomes to effort did not always produce conceptual change. They had different perspectives on effort and conducted different effort activities to resolve the cognitive conflict. In addition, these effort activities appeared to include their motivational beliefs, metacognitive and volitional strategies. The results of this study indicate that in order for the conflicts to lead to change, students need to have the perspective on effort implying the use of the self-regulated learning strategy and to conduct effort activities based on them. Beyond cold conceptual change, this article suggests that there is a management strategy of cognitive conflict in the classroom context.

  • The purpose of this study was to examine the role of cognitive conflict in the conceptual change process. Ninety-seven high school students in Korea participated in this study. Before instruction, we conducted pretests to measure learning motivation and learning strategies. During instruction, we tested the students' preconceptions about Newton's 3rd Law and presented demonstrations. After this, we tested the students' cognitive conflict levels and provided students learning sessions in which we explained the results of the demonstrations. After these learning sessions, we tested the students' state learning motivation and state learning strategy. Posttests and delayed posttests were conducted with individual interviews. The result shows that cognitive conflict has direct/indirect effects on the conceptual change process. However, the effects of cognitive conflict are mediated by other variables in class, such as state learning motivation and state learning strategy. In addition, we found that there was an optimal level of cognitive conflict in the conceptual change process. We discuss the complex role of cognitive conflict in conceptual change, and the educational implications of these findings.

  • This study investigates how cognitive and affective conflict affect performance and social outcomes in the new product situation. We examine the corporate, project, and personal characteristics that determine the level of inter-functional conflict between marketing and R&D. From a survey of Korean high-tech companies, we found : (1) time pressure was positively related to cognitive and affective conflict, (2) joint reward systems, interdepartmental connectedness, and years of education were negatively associated to cognitive conflict, (3) while cognitive conflict was positively related to new product creativity and NPD performance, affective conflict was negatively associated to marketing-R&D integration and perceived effectiveness of the relationship, as well as new product creativity and NPD performance.

  • 개념변화에서 인지갈등의 중요성에도 불구하고, 실업계 학생들의 인지갈등 특성에 관한 연구는 찾아보기 힘들다. 이 연구의 목적은 실업계 학생들의 인지갈등 유형을 알아보고, 그 유형에 따른 인지갈등 특성을 밝혀보는 것이다. 이 연구에서 연구자들은 실업계 학생들이 작용과 반작용 개념과 관련된 불일치 상황에 직면했을 때, 인지갈등 유형에 따라 학생의 동기적 요인과 인식론적 신념이 어떻게 인지갈등 과정에 영향을 미치는가를 탐색하였다. 연구결과, 많은 실업계 학생들이 낮은 수준의 인지갈등을 경험하고, 불일치 현상을 설명하는데 수동적이거나 갈등 상활을 해결하려는 시도를 쉽게 포기하려는 경향을 보여주었다. 왜냐하면 이 학생들은 교사의 절대적 지식에 의존하려는 인식론적 신념을 갖고 있고, 쉬운 과제 선호성과 교사의 인정에 초점을 맞추는 외적 동기를 갖고 있기 때문이다. 따라서 교사들이 인지갈등 과제를 제시할 때, 실업계 학생들의 개념변화를 촉진하기 위해서는 이러한 인지갈등 특성을 잘 인식해야만 한다.

  • 이 연구는 인지갈등전략을 사용한 중학생들의 작용과 반작용에 관한 수업에서 인지갈등 해소 지연에 따른 학생들의 개념변화의 차이를 알아보았다. 인지갈등이 일어나고 있는 동안 학습자는 의식적 무의식적으로 인지갈등을 해소하기 위해 여러 정신 과정과 육체적인 활동이 이루어지리라 생각할 수 있다. 그러나 아직까지 이에 대한 연구는 별로 이루어진 바가 없었다. 이 연구에서는 인지갈등을 유발한 후 어느 정도의 시간이 경과한 다음 인지갈등을 해소하는 것이 개념변화에 효과적인가를 알아보기 위해 연구대상을 즉시해소 집단, 2일지연해소 집단, 7일지연해소 집단으로 나누었다. 세 집단에 대해서 작용과 반작용에 관한 문항으로 사전개념검사와 해소직전개념검사, 사후개념검사, 지연개념검사를 실시하였으며, 설문조사를 통해 지연해소 집단의 학생들이 인지갈등 해소를 지연하는 기간 동안 인지갈등 해소를 위해 어떠한 활동을 하였는지 알아보았다. 연구결과는 다음과 같다. 첫째, 즉시해소 집단이 지연해소 집단보다 개념변화 정도가 유의미하게 큰 것으로 나타났다. 즉, 즉시해소 집단이 2일지연해소 집단과 7일지연해소 집단보다 사전개념검사에서 오개념을 가졌던 학생들이 지연개념검사에서 과학적 개념으로 더 많이 바뀌었다. 둘째, 지연해소 집단의 학생들은 인지갈등 해소를 위해 동료와의 상호작용을 통한 방법을 가장 많이 사용하였다. 셋째, 지연해소 집단 내에서 인지갈등 해소를 위해 시간을 소모한 학생이 그렇지 않은 학생보다 개념변화가 유의미하게 큰 것으로 냐타났다. 위의 연구결과를 볼 때, 인지갈등전략을 사용한 중학생의 과학수업에서 인지갈등 해소를 지연시키는 것보다 불일치 상황을 인지하고 있는 상태에서 즉시 해소기키려고 하는 것이 개념변화에 더 효과적임을 알 수 있다.

  • 과학교육에서 개념학습이 중요한 위치를 차지히는 만큼, 개념변화에서 인지갈등의 역할은 크다. 그러나 과학교육 연구에서 인지갈등을 유발하는 방법이 과연 얼마나 효과적인지 다수의 인원으로 검증한 연구가 많지 많으며, 같은 상황임에도 학생에 따라 인지갈등과 개념변화의 정도가 다른 원인에 대한 연구도 찾아보기 어렵다. 본 연구는 이러한 의문을 해결하여 인지갈등을 올바로 이해하고, 앞으로의 개념변화 학습에 보다 효과적으로 활용하고자 인지갈등과 개념변화에 미치는 학습자 특성에 따른 차이를 알아보았다. 연구 대상은 대도시, 중소도시, 읍지역의 777명 남녀 중학생이며, 학습자 특성이란 과학 개념학습과 인지갈등 관련 문헌의 고찰과 과학교육 전문가 대상의 설문 조사를 통하여 대표적인 6가지 학습 변인으로서 지능, 인지수준, 성적, 인지양식, 성격, 과학에 관련된 태도등이다. 연구 결과, 인지갈등 전략에 의한 개념변화에서, 인지갈등의 정도는 성격과 태도 등 정의적 영역과 관계 있으며, 과학적 개념으로의 변화는 지능, 성적 등 지적 영역과 관계 있었다.

  • Purpose - Social media platforms have presented individuals with an opportunity to create and maintain their social relationship through the use of social media services. However, such social relationship has a negative influence on users' interest in social media. Design/methodology - Using structural equation modeling, this study seeks to examines the effects of different social media conflicts (individual and social conflicts) on users' psychological internal state, especially user apathetic behavior Findings - The findings confirm that, among social media conflicts, social-related conflict, especially social interaction overload has a negative effect on cognitive resonance, while individual conflict has the highest effect on cognitive dissonance. Also, cognitive dissonance has a much greater effect than cognitive resonance on user resistance, this means that users' negative perception of social media has a greater influence on their resistance. Lastly, user's resistance was found to have a positive influence on user's apathetic behavior. Originality/value - In other to capture social media Apathetic behavior, this study focus on social media conflict perspective, which includes social-related conflict and individual conflict, which are found to influence users' internal states towards social media and further induce social media behavior. This study is unique because it is among the first to explore social media apathetic behavior by focusing on the influence of both external social media conflict and internal state. Also, this study proposed that social related conflict has a higher negative influence on WeChat user than individual related conflict.

  • The idea that students must experience cognitive conflict before conceptual change can occur is not new. In light of this idea, many teaching strategies have been applied in educational practices. However, there is not much literature about how students are experiencing cognitive conflict, how this experience affects students learning processes, and how we use that knowledge to improve our science instruction. This study aimed to propose possible answers about these questions. In this paper, we conducted the first question as a first part of our research. To do this, we reviewed related literature and analyzed protocols that were produced in previous studies. As a result, a model of cognitive conflict was developed. This study's findings may lead to further understanding and use of students' cognitive conflict, which has a complex role in science instruction.
