  • The purpose of this study is to investigate preservice earth science teachers' mental models through applications of Coriolis force experiment apparatus. After the root of preconception was examined by face to face interviews based on the questionnaire, five preservice earth science teachers were finally selected for this study. The mental models about concept of Coriolis force was classified into naive mental model, static unstable mental model, dynamic unstable mental model, and scientific mental model through the result of individual interviews and their drawings. According to the mental model analysis about Coriolis' force conception, students C and M showed naive mental model about concept of Coriolis force before experiment. After the experiment, student M's model changed to static unstable mental model. Student C's model improved to dynamic unstable mental model. In adiition, students D and O's model improved from static unstable mental model to dynamic unstable mental model. In the case of student B, the dynamic unstable mental model was maintained after the experiment, however, student B's preconception changed to scientific concept. It turned out that a change occurred from low mental model level to integrated mental model after the application of the developed Coriolis' force experiment apparatus. According to the results, national curriculum is similar to static unstable mental model and the result of developed Coriolis' force experiment apparatus is similar to dynamic unstable mental model. It is suggested that it become the theoretical foundation to develop more comfortable and advanced Coriolis force experiment apparatus by improving the experiment apparatus.

  • Purpose: The goal of this paper is to offer practical suggestions for developing, implementing, and maintaining a successful school mental health program based on the model of a school mental health program for middle school students at the Namgu Hyosarang adolescent Mental Health Center. The model will be divided into six areas and the challenges and future direction of this program: creative approach to funding, creative staffing, education, training, needs assessment & resource mapping, collaboration and partnerships in a school mental health program, and developing an outcome evaluation research. Method: This is a descriptive study of the school mental health program model for middle school students of Namgu Hyosarang Adolescent Mental Health Center implemented over a four year period. Conclusion: Within this paper, a blueprint that can guide the development and implementation of school mental health programs has been offered. The actual application of this model will vary depending on the structure and goals of individual programs and schools. This model of our center has been identified as an effective school mental health program and the actual application program in regular learning times to middle school students. Establishing guidelines about the types of activities necessary for the successful implementation and sustainability of a school mental health program constitutes the first step in standardizing this process, and the school mental health movement continues to receive national recognition as a viable services delivery model for adolescents in need of mental health services. The recommendations outlined indicate that a school mental health program is more effective and necessary than the clinical service of a psychiatric hospital for adolescents' emotional/behavioral problems.

  • When modeling students' conceptual understanding, there are several different frameworks, among which are the alternative conception framework and the mental model framework, which converge to suggest a form of knowledge representation. However, little research has explained how they are different from each other and from memory. The purpose of this study was to develop a new mental model theory that integrates the different terminologies and their background theories, which refer to students' ideas not only in science education, but also in other research areas. For this purpose, at first, we compared different terminologies including alternative conception, p-prim, and mental models, and the underlying theories used for representing students' ideas in learning science. Through such comparison, we tried to find the relationship among them. We reviewed related literature and synthesized the results from both cognitive science (related research areas) and science education approaches, especially, Vosniadou's mental model theory. Based on reviewing previous studies, we have developed a preliminary mental model theory 'an integrated theoretical structure of mental models'. We applied the new mental model theory to interpret data on students' ideas about circular motion from our previous research. We expect our new mental model theory will help us understand how students form their own ideas in science from an integrated perspective.

  • In science education, the research on students' conceptions has been started in early 1970. From the early 1980, the research on students' conceptions stimulated the research on conceptual change. Recently, mental model has been a theoretical background in concrete arguments on "how students' conceptions are constructed or created?" Mental model has been studied early in cognitive psychology, and several researchers have studied it partially in science education area. In this study, we compared different theories that explained students' conceptions in, mainly, physics. Further we discussed the possibility of mental model as a theory that could integrate different explanations about students' conceptions from different theory.

  • The objective of this study is to clarify how high school students recognize the mental model of the global environment and how they conceptualize the environment. Using the drawing and interview, 25 high school students participated in the survey and were asked to visualize the environmental elements of the global environment and describe the environment they portrayed. The dominant mental model in the present was Mental Model 3: the environment as a place impacted or modified by human activity. Yet, the partial mental model in the future was Mental Model 2: the environment as a place that supports human life. The implications to environmental science education are explored.

  • This study explored pre-service teachers' mental models about eclipse phenomena to investigate their understandings on the earth science concept needed f3r an integrated approach. We conducted in-depth interviews with two different contexts on 30 secondary and 36 primary pre-service teachers participants, and analyzed phenomenological primitives (p-prims) and facets of causal explanations about eclipses. Based on this study, we identified four different levels of mental models about eclipses. Four mental models were categorized as (1) Screening model, (2) Orbital plane model, (3) Hybrid model, and (4) Shadow cast model. Screening model is a flawed mental model, orbital plane model is an incomplete correct mental model, and shadow cast model is a scientifically correct mental model. Hybrid model, composite of two or more mental models, use multiple mental models simultaneously. Orbital plane model was the most widespread mental model in secondary pre-service teachers group, whereas screening model was used frequently in primary group. It was found that the level of mental model could be determined by the level of facet and p-prims. We confirmed context sensitivity of the mental models and perceived the necessity of integrated approaches to promote progression of mental models. Implications of our findings for enhancing pre-service science teachers' topic-specific pedagogical content knowledge (PCK) associated with eclipse phenomena are also discussed here.

  • Objectives : The purpose of this study was to examine the results of the 2013 students' mental health school-community cooperative model. This study investigated teachers' awareness of change in school environment and analyzed the follow-up conditions of students. Methods : The sample consisted of 55 schools which participated in the 2013 students' mental health school-community cooperative model. Two questionnaires were used : one was composed of items about mental health resources, school policy and practice, school climate and community referral, and the other was on management of follow-up conditions for high risk students. Results : First, teachers' awareness regarding school mental health resources, school policy and practice, school climate, and community referral showed positive change. That is, the 2013 students' mental health school-community cooperative model works for improving teachers' interest, awareness and effort regarding mental health. Second, students, who were found by screening test and observation, were managed continually. Most students received follow-up interventions at school, and half of the students were referred to a specialized institution such as a mental health clinic, Wee center, personal counseling center, community welfare center, and so on. Conclusion : This study was a preliminary research, therefore follow-up studies are required in order to accomplish the 2013 students' mental health school-community cooperative model.

  • Icons are the main element of the graphic user interface (GUI). They can help users perform effectively on the computer, especially when the icons reflect user`s mental model. However, few studies in Korea represented Korean users` mental models in icon design. The purpose of this study, therefore, was to ascertain whether existing icons agreement with Korean twentieth mental model, and to deduce properties of Korean twentieth mental model. To do that, 10 icons from two commercially available toolbar-icons of word processing programs were compared with the newly developed icons, which were developed to represent Korean user`s mental modelthrough interviews, surveys, and mental model sketches. The results show that five new metaphors were found: a dog-eared part on the bottom right corner new for new document, a magnifying glass for search, a red pencil for spell-check, `+` and `` signs in the magnifying glass for zoom, and a yellow post-it for paste. These new icons were preferred to the existing. Korean twentieth users preferred rather complex and dynamic icons than simple and static ones even though icon development guideline said simple icons are better.

  • An application that has a simple user interface not only motivates a user to continue using the application, but also enables the user to develop their mental model for the application - the like of which is a product of their interaction with the application. In the information systems literature, little empirical research has been undertaken on the effects of the mental model and motivation on smartphone users' behavioral beliefs. Therefore, the aim of this study is to suggest a research model that can examine the following: 1) the effects that the mental model has not only on smartphone users' behavioral beliefs (that is, perceived usefulness and ease of use of an application) but also on their behavioral intention to use an application and 2) the effects that smartphone users' intrinsic motivation has on their behavioral beliefs through an expansion of the mental model. A survey is conducted, and structural equation modeling is then used to analyze the survey data. The results, through consideration of variables such as intrinsic motivation, perceived usefulness, perceived ease of use, and user satisfaction, indicate that the mental model has an indirect effect on a user's intention to use an application.
