  • It has been known that the tool characteristics embedded in physical tools and virtual tools act with different underlying mechanisms in a user's knowledge acquisition and conceptual understanding. This overview study examines the learning process through the use of physical and virtual tools from the perspective of conceptual frameworks, affordability that tools present, and the depth of cognitive engagement that occurs in the process of learning concepts through various learning activities. Based on the conceptual frameworks, the results of previous comparative studies were reinterpreted. It was found that what mattered for learning is the amount of new information that a tool provides and the different level of cognitive engagement that students use through various learning activities. Finally, the implications to be considered when teachers use physical and virtual tools to help students better understand various concepts are discussed.

  • While we interact with other people or objects, the brain continuously updates our own body schema to recognize the agent of observed actions. The Extrastriate Body Area (EBA) provides an initial interface for the sense of agency by integrating visual inputs of body parts with internal signals related to self-generated body movements. Less is known, however, about how the functional use of tools contributes to such processes. Here, we investigated whether tool-specific affordance would differentially affect the neural responses in the EBA depending on the agency of imaginary actions. In each trial we presented a picture of an object in a rectangular frame. Objects were either the tools typically brought towards the body (body tools; e.g., telescope, earphones) or away from the body (world tools; e.g., pen, dice; Rueschemeyer, Pfeiffer, & Bekkering, 2010). Depending on the color of the frame, participants imagined either themselves or the other person using the tool (self vs. other conditions). These four types of trials were randomly intermixed with blank trials. As results, independently localized right EBA regions of interest showed greater activation when participants imagined themselves using body tools than using world tools whereas no such differential activations were found when they imagined the other person using the tools. The postscan test revealed no significant difference in vividness of imagery between the self and other conditions. Our results suggest that the EBA incorporates functional affordance of tools into the body schema in order to enhance the sense of agency and to guide our own actions.

  • The purpose of this study is to review the role of dragging in dynamic geometry environments. Dragging is a kind of dynamic representations that dynamically change geometric figures and enable to search invariances of figures and relationships among them. In this study dragging in dynamic geometry environments is divided by three perspectives: dynamic representations, instrumented actions, and affordance. Following this review, six conclusions are suggested for future research and for teaching and learning geometry in school geometry as well: students' epistemological change of basic geometry concepts by dragging, the possibilities to converting paper-and-pencil geometry into experimental mathematics, the role of dragging between conjecturing and proving, geometry learning process according to the instrumental genesis perspective, patterns of communication or discourse generated by dragging, and the role of measuring function as an affordance of DGS.

  • 국내 인터넷 활용인구의 증가와 함께 연령층의 확대로 초등학생 인터넷 이용률은 날로 높아지고 있다. 어린이들에게 인터넷은 이미 친숙한 매체이며, 효과적인 학습도구로 활용되고 있다. 아이콘은 사용자가 클릭을 통해 다른 곳으로 이동할 수 있도록 방향성을 제시하는 navigator 역할로 사용자들의 행동을 유도하는 기능을 가지고 있다. 어린이를 주 이용 대상으로 하고 있는 어린이 포털 사이트의 경우 아이콘의 기능은 무엇보다 중요하다. 그러므로 아이콘을 지각하는 어린이의 감성을 파악하는 것은 필수적인 과정이다. 따라서 이러한 어린이 포털 사이트의 아이콘을 제작함에 있어, 사이트 방문자인 어린이의 감성을 조사하여 효과적인 아이콘 설계 방안을 제시하고자 한다. 이를 위하여, 이용자 접속률이 높은 세 개의 국내 어린이 포털 사이트의 아이콘 샘플을 추출하고 이를 서울지역 초등학생을 대상으로 선호 이미지 형용사를 조사하였다. 이는 향후 어린이를 대상으로 한 다양한 서비스에 기초 자료로 활용될 수 있을 것이다.

  • Past research showed that presence of others induces morally desirable behavior and stricter judgments. That is, presence of others makes people become a moral being. On the other hand, little research has been conducted to test what effects facial expression of others have on moral judgments. In this research, we tested the effects of emotion exposed by facial expression on moral judgments. To this end, we presented descriptions of immoral or prosocial behavior along with facial expression of various emotions (in particular, disgust and happiness), and asked participants to make moral judgments on the behavior in the descriptions. In Experiment 1, facial expression did not affect moral judgments, but variability of judgments was increased when descriptions and facial expression were incongruent. In experiment 2, we modified potential reasons of the null effect and conducted the experiment using the same procedure. Subjects in Experiment 2 made stricter judgments with disgust faces than with happy faces for immoral behavior, but the effect did not occur for prosocial behavior. In Experiment 3, we repeated the same experiment after having subjects to consider themselves as the actor in the descriptions. The results replicated the effects of facial expression in Experiment 2 but there was no effect of the actor on moral judgments. This research showed that facial expression of others specifically affects moral judgments on immoral behavior but not on prosocial behavior. In general discussion, we provided further discussion on the results and the limitations of this research.

  • Animal models can provide a useful tool for the study of some aspects of psychiatric disorders and their treatment. The four criteria for the evaluation of animal models of psychiatric disorders are as following : 1) similarity of inducing conditions 2) similarity of behavioral state 3) common underlying neurobiological mechanisms 4) reversal by clinically effective treatment techniques. Several animal models have been proposed for schizophrenia : phenylethylamine model, L-dopa model, hallucinogen model, cocaine model, amphetamine model, phencyclidine model, noradrenergic reward system lesion model, reticular stimulation model, social isolation model, conditioned avoidance reaction, catalepsy test, paw test, self-stimulation paradigms, latent inhibition paradigms, blocking paradigms, prepulse inhibition of the startle reflex, rodent interaction, social behavior in monkeys, hippocampal damage, high ambient pressure, and models using selective breeding. Among them, animals with bilateral lesion of the hippocampus may provide an adequate animal model for several symptoms of schizophrenia, and ketamine model can reproduce negative symptoms and cognitive deficits as well as positive symptoms of schizophrenia. In conclusion, no model of schizophrenia is entirely representative of the disease, and findings gleaned from model systems must be cautiously interpreted. Furthermore, the process of developing and validating animal models must work in concert with the process to identify reliable measures of human phenomenology.

  • Safety education delivered to construction workers in a lecture manner has limitations in concentration and immersion, so delivery power and interest are low. In order to improve unstable behavior through education and prevent safety accidents, it is necessary to change the paradigm to hands-on education. Purpose: Experiential safety education aims to contribute to preventing accidents for construction workers by quickly recognizing risks, improving emergency response skills, and verifying the effectiveness of pre- and post-learning. Method: Based on a survey of workers who experienced the same work environment as the actual construction site, an opinion survey on the pre- and post-safety experience education and a variable measurement tool were planned, and a research hypothesis was established. Results: The Bayesian theory and MC simulation analysis were used to analyze the structural equation model, and the change in construction worker behavior was confirmed through the intended safety (A), non-experiential education in the sub-area of anxiety (B), average, standard deviation, and minimum and maximum values. Conclusion: The effect of education and industrial accidents are reduced only when construction workers are motivated to participate.

  • The gender equality consciousness of public service workers is important since it is not only existed as attitudes and behaviors but also utilized as a policy tool. Therefore, it should be developed to improve practical abilities which enable them to analyze and integrate their own works based on gender perspective. This study examined the experiences and attitudes toward gender egalitarianism education, based on a survey of public service workers in Daejeon city(699 men and 457 women). The results can be used for desirable changes of gender egalitarianism education. We can see that the will of men to participate in the gender egalitarianism education is lower compared to it of women. To expand gender egalitarianism education, the motivation and legislation for participating in education, and the development of various education programs according to gender, age and positions are needed.
