  • Virtual reality (VR) provides a virtual experiment (VE) context consisting of information presented to the senses of the user. The user perceiver and interprets the VE context, and then naturally recognizes a level of realism in the VE. Presence is often thought of as the sense of 'being there' in the n. Presence includes overall feelings about the information conveyed from a virtual avatar to the user. Therefore, there must be brain mechanisms for integrating sensory information about presence.'Feeling of presence' is related with the user's cognition and perception about information on communication through medium. Thus 'feeling of presence' may characterize perceptual mechanisms in the brain. We studied these mechanisms by presenting a VR that consisted of an avatar telling a story about a social conversation. We performed covariance analysis on subjective brain activity (fMRI) during the story presentation with a presence score. The data analysis revealed that activity in several brain areas was correlated with the presence store. A positive correlation was shown in the right lingual gyrus, right cuneus, left lingual gyrus, right fusiform gyrus, left inferior temporal gyrus, anterior cingulate cortex and right posterior cingulate cortex of the brain. This study showed the brain mechanism to be related the feeling of presence and brain activities in our subjects, using VR to communicate information.

  • To examine the limitations of the the Blosser's (1973) 'Question Category System for Science', which is mainly applied to research in science education in Korea, we analyzed 30 hours of class conversation in a small group program (for first-year middle school students) with a researcher participating as a teacher. When classified according to Blosser's (1973) classification system, distinguishing between 'open and closed questions' was difficult. Questions with the same content were classified into different types depending on their context, whereas some questions could not be classified appropriately. Additionally, higher-level questions (open questions) were not more effective than lower-level questions (closed questions) in improving students' thinking ability or participation in class. The questionnaire's effect differed depending on the information provided by the teacher before questioning, and in many cases, previous question influenced the next questions. However, in the science education questionnaire research based on Blosser's (1973) classification, which is mainly conducted in Korea, each individual question is classified according to the cognitive level, disregarding the influence of context and prior and subsequent questions and the quality of instructions is evaluated by the frequency of higher level questioning. The results of this study indicate that the method of evaluating instruction quality based on the frequency of high-level questioning, which is currently conducted in domestic science education inquiry research, should be avoided.

  • Film literacy comprises the process of producing a new creation through understanding the elements that make up a film, the content of a film, and a critical and creative thinking process. Film literacy is employed in fields such as composition, science, social studies, and geography, and, additionally, it is used to cultivate humanities literacy and critical thinking skills. Yet despite the large proportion of the film script in the movie, it is not easy to find literacy education cases that use film English as a teaching method. Film English is a practical and authentic material, and is suitable as an English learning material in an EFL context like Korea. However, the approach of using films to teach and learn differs according to the content and genre of a film. Thus, the teacher may have a difficult time organizing and preparing for class. This study suggests six class activities that can be commonly applied to English classes using films based on the areas of critical, cultural, and creative (3Cs) activities. Four hundred and five college students taking Movie English classes participated in the present study and frequency analysis was conducted to find out their preferences through a questionnaire survey. The results from conducting class activities in university liberal arts classes suggest that the most preferred activities of students are related to cultural, critical, and creative, in that order. Creative activities that are far beyond English instruction utilizing various digital tools or providing additional reading materials can be a burden on learners.
