The purpose of this study is to investigate the effects of the causal thinking activity of Let's Think Through Science(LTTS) program on causal thinking and science process skills of elementary school students. Four classes of 4th graders (N=119) from a elementary school were divided into the control and the experimental groups. Causal thinking activity of LTTS program was used with the experimental group, while the normal curriculum was conducted with the control group. Both groups were given a pre-post test on causal thinking abilities and science process skills. And the experimental group was given 15- item questionnaires analyzing of perception on LTTS program. This study revealed that causal thinking activity of the LTTS program were effective on the development of students' causal thinking abilities and science process skills. ANCOVA results revealed that the scores of causal thinking abilities for the experimental group significantly higher than those of the control group. In the sub-tests of the causal thinking abilities all categories were effective. And ANCOVA results of the science process skills were also effective. Science process elements of observation, recognizing of a problem were significantly higher. And elementary students preferred to the causal thinking activity of LTTS program so that it was interesting, useful, helpful to each other in studying science.

최근 코로나19 상황으로 인한 비대면 교육의 확산으로 온라인 교수·학습 및 평가 도구에 대한 관심이 높아지고 있다. 도구의 효과적인 활용을 위해서는 학습자의 정의적, 인지적 변인 간의 구조적 영향력과 인과 관계에 대한 규명이 필요하다. 본 연구는 '온라인 저지'를 활용하는 프로그래밍 교육에서 도구의 활용 횟수, 자기효능감, 몰입, 컴퓨팅 사고력, 논리적 사고력으로 구성된 연구 모형과 경쟁 모형을 설정하고, 모형의 적합도와 경로 분석을 실시하였다. 분석 결과, '도구의 활용 횟수 → 자기효능감 → 몰입 → 논리적 사고력 → 컴퓨팅 사고력'에 이르는 인과 관계를 규명하였고, 도구의 활용 횟수가 학습 동기를 거쳐 사고력에 영향을 미치는 경로 상에 '자기효능감 → 몰입'의 이중 매개 효과, 또는 '몰입'의 단독 매개 효과를 확인하는 동시에 '몰입 → 자기효능감'의 이중 매개 변인으로는 도구의 활용 횟수가 사고력으로 발현되지 않음을 확인하였다. 한편, 동일한 경로 상에 '논리적 사고력 → 컴퓨팅 사고력'의 경로는 규명되었으나, '컴퓨팅 사고력 → 논리적 사고력'의 경로는 규명되지 않았다.

The purpose of this study is to analyze the school autonomy policy based on the system thinking perspective using causal loop diagrams. School autonomy was the main educational policy concerning school domain during the last government and was the instrument for school-based management, but it was not implemented effectively in site. The school autonomy policy practically disappeared as an explicit policy agenda in the current government. This study displays causal loop diagrams about the policy's logic and contents of school autonomy, in terms of curriculum, human resource management, and a supportive system. The causal loop diagrams depicting the implementation of the school autonomy policy are suggested concerning excessive enforcement and the confirmative mechanism for policy implementation. The conclusion provides some research implications and future directions.

Factors and causal structures of pre-service elementary teachers about the critical thinking and the scientific literacy competency were investigated in this study. The third grade university students and the first grade university students in the metropolitan city participated in this study. The factor analysis method and the structural equation modeling method were used for the data analysis, and the following results were obtained. First, the third grade university students and the first grade university students recognized 'inquisitive thinking' factor and 'reflective thinking' factor as factors of the critical thinking, and 'scientific explanation' factor and 'evidence-based conclusion' factor as factors of the scientific literacy competency respectively. Second, the third grade university students showed more the influence from 'reflective thinking' factor to 'scientific explanation' factor and from 'reflective thinking' factor to 'evidence-based conclusion' factor than the first grade university students.

Adolescent media addiction has emerged as an important social agenda in Korea. However, there has not been enough discussion on the causal structure of media addiction and policy interventions. The objective of this study is to identify and assess the mechanism of the existing and the revised Shutdown policy based on the systems thinking approach. To achieve this purpose, we establish the relationship between media usage, flow, and addiction, and develop a causal loop diagram. Based on the causal loop diagram, we explore the causal structure of two policy scenarios: shutdown policy and deregulation. Our study suggests that policy interventions inducing direct parental control on children's media usage time are ineffective since the time control reduces children's autonomy, which helps alleviate media addiction. Therefore, this study suggests that policy intervention should focus on alleviating addiction itself rather than on controlling media usage time.

This paper deals with the policy failure in housing markets. In order to understand basic mechanism leading to policy failure, systems thinking and system dynamics modeling is applied to housing markets and housing policy. This paper will show different set of causal maps on housing policy, and compare causal reasons of housing policy and its critics.

The purpose of this research is to understand a structural relationship between financial regulations and security industry based on the systems thinking perspective using causal loop analysis. As a result, the positive regulations on security technology against finance security incidents shrink the autonomy of the security industry and will deteriorate the competitiveness of the security industry through the unknown feedback loop. The conclusion provides the direction that policy makers understand causal loop diagram related current regulations and open enough to the consideration of the negative regulations.

This study investigated dynamic causal relationship between CSR implementation and consumption of environmentally friendly fashion products through systems thinking. Based on literature review and empirical research, we drew causal loop diagram for CSR implementation in environmentally friendly fashion product industry. By analyzing feedback loops, we found that companies and consumers interact in the process of CSR activities. In the process of CSR implementation, companies and consumers are closely related and affect each other as stimuli and prior condition. This study suggests that companies adopt push strategy to actively create demand by developing and promoting environmentally friendly fashion products and that companies communicate with consumers in order to be recognized and rewarded by consumers for their CSR activities. In addition, this study suggests that consumers not only support companies of CSR activities but also actively boycott anti-environmental companies by collective action.

The purpose of this paper is to analyze the functional changes of local educational authority policy based on the systems thinking perspective using causal loop diagrams. In the past, the main function of the local educational authority was to manage and supervise schools. Through this policy, local educational authority would be transformed into a support agency. However, this policy did not achieve the goal, was to cause confusion and require improvement. This study shows structured causes of the problem based on systems thinking. These diagrams make it possible for educational policy makers to provide ideas, although they have some complicated environment. The findings indicate that based on systems thinking in this policy can help those who related to policy decision than existing diagnosis method.

This study explores hedge fund characteristics that affect hedge fund performance, namely, fund size, fund age, and performance fee. Previous studies have examined relationships between hedge fund characteristics and fund performance using singular and static thinking to report inconsistent findings without providing full understanding of the causal relationships among variables. To identify that comprehensive causal relationships between hedge fund characteristics and hedge fund performance, this research applies the system dynamics perspective, which allowed demonstration of the interactions within the overall system beyond the singular causal relationships between hedge fund characteristics and performance found in existing traditional research. This study contributes to existing literature in the following ways. First, it overcomes the limitations of singular research methodologies by looking at the integrated system of hedge fund characteristics and fund performance from a bird's eye view based on their dynamic feedback relationships. Second, policy suggestions in terms of regulation and education are presented as growth strategies for the sustainable development of the Korean hedge fund market.
