  • study investigated the influences of the forms of verbal external representations and students' verbal learning style in learning chemical concepts with drawing as a method to assist students in connecting and integrating multiple external representations. Seventh graders (N=133) at a coed middle school were assigned to formal drawing (FD) and personalized drawing (PD) groups. Students in the PD group were provided words at personalized style as verbal external representations for drawing, while those in the FD group were provided words at formal style. All students were taught about Boyles Law and Charless Law for two class hours. Results revealed that the scores of a conception test for the PD group were significantly higher than those for the FD group. In a situational interest test, students with strong verbal learning style preference scored significantly higher than students with weak verbal learning style preference in the two groups. Most PD group students were found to prefer to read verbal external representations at personalized style for drawing rather than at formal style, and perceived their activities positively upon cognitive, affective and motivational aspects. Students with strong verbal learning style preference had more positive perceptions about their activities than students with weak verbal learning style preference especially upon affective and motivational aspects.

  • Phantasy is the psychic reality in which drive, sadism and anxiety are represented and constructed. It is one of important metapsychological concepts of the psychoanalysis which explains the formations of symptoms, internal psychic structure, and the mutual relationship between internal subjective world of man and external world. Through the understanding of phantasy we can approach the man's unconsciousness and fathom the structure of the subject itself. Especially S. Freud and M. Klein's psychoanalysis give us the deep insight into the phantasy, on the basis of which we can investigate the cause and structure of the pathological phenomena of the man.

  • The purpose of this study was to analyze the uses of the external representations in the $3{\sim}6th$ grade science textbooks developed under the 7th National Curriculum on the basis of the theories and the research results on learning with the multiple representations. The results showed that the frequencies of the macroscopic external representations were higher than those of the symbolic external representations. The external representations with drawing and/or writing, especially writing, were used more frequently than those without drawing and/or writing. However, the most of the external representations were rarely used according to the principles and/or the theories (e.g., personalization principle, dual coding theory, cognitive load theory, and social constructivism theory) for effective uses of the multiple external representations in the science textbooks. The present study provides the guideline to establish the effective uses of the external representations in the science textbooks that not only meet learners but also teachers.

  • Large Jar had been manufactured and used broadly in Mahan area from late second century. At first, it was used for various purposes, for example storing utensils at household and religious service at tombs. But it's usage was shifted with the political expansion of Baekje. In late third century, large jar coffin appeared in tombs as an important burial unit at Yeongsangang river valley. It has specific traits such as saw blade-shaped design etc. That style is distinguished from Baekje's. Unification of form and style of large jar coffin signify the socio-political distinction between Yeongsangang river valley and Baekje. Large jar coffin was used emblemic style for this purposes by the political elites of the Yeongsangang river valley. This process was caused by political reason, that is, need for integration of the Yeongsangang river valley communities against the territorial expansion of Baekje state.

  • Many e-learning programs in Korea use lecture as a main instructional method. A meta-analysis study reports that e-learning programs using lectures were the most ineffective. In addition, many researchers in the field of distance education contend that the active participation of learners is the key to the success of e-learning. These imply why we can easily find many people who don't have good impression about e-learning. The quality of e-learning depends on the application of appropriate pedagogy. This study aims to present the implications for the improvement of e-learning programs in the Republic of Korea by analyzing the psychological characteristics reflected on the e-learning programs in the U. S. that have been improved through design research for a long time. The result shows that the e-learning programs in the U. S. have five major psychological aspects, i.e., reflective thinking, collaborative interaction, knowledge construction, situated action, and utilizing multiple representations. Consequently, this study suggests that e-learning programs in the Republic of Korea need to reflect learning principles such as learning by doing, situated learning, collaborative learning, learning with multiple representations in order to improve the quality.

  • This study investigated the effects of varying visuals in drawing and writing as methods to assist students in connecting and integrating multiple external representations provided in learning the particulate nature of matter. Seventh graders (N=233) at a coed middle school were assigned to control, static drawing (SO), dynamic drawing (DD), static writing (SW), and dynamic writing (DW) groups. The students were taught about "Boyle's Law" and "Charles's Law" for two class periods. Two-way ANCOVA results revealed that the scores of a conception test for the two drawing (SD, DD) groups and the two writing (SW, DW) groups were significantly higher than those for the control group. Within the writing groups, students of lower spatial visualization ability in the DW group scored significantly higher than those in the SW group. However, no significant differences were found in the scores of the conception test for the two drawing (SD, DD) groups regardless of students' visualization ability. Researchers also found that most students in both DD and DW groups had respectively positive perceptions of dynamic visuals in drawing or writing.

  • This study investigated the influences of small group discussion and students' visual learning style in learning chemical concepts with drawing and writing as methods to assist students in connecting and integrating multiple external representations. Seventh graders (N=449) at a coed middle school were assigned to individual drawing (ID), pair drawing (PD), individual writing (IW), and pair writing (PW) groups. All students learned "Boyle's Law" and "Charles's Law" for two class periods. Analyses of the results revealed that the students in the PD group, regardless of students' visual learning style, scored significantly higher than those in the ID group in a conception test. The scores of the students with strong visual learning preference in the PW group were significantly higher than those in the IW group in the conception test, while the scores of the students with weak visual learning preference were not significantly different between the two groups. Although the conception test scores of the PD group were higher than those of the PW group, the difference was relatively small. It was found that most students in both PD and PW groups perceived pair drawing and pair writing positively upon cognitive and motivational aspects.

  • In this study, we tried to find out the level of inductive reasoning ability and the aspects of visualization components shown in students in the class using exploratory software for the 'congruence and symmetry' unit in the second semester of the 5th grade of elementary school. To this end, classes using GeoGebra, one of the exploratory software, were conducted for a total of 19 students in one class of fifth graders in elementary school, and the results of the students' activities were analyzed. As a result of this study, the level of inductive reasoning ability of students remained at a similar level or developed, and it was shown that students inferred new properties of shapes using various functions of software inductively. In addition, in terms of visualization, students were able to quickly and easily draw shapes that met the conditions, and unlike the paper-and-pencil environment, using the 'measurement' and 'symmetry' functions, they transformed and manipulated complex yet precisely congruent and symmetrical external representations. Based on these analysis results, implications for the use of exploratory software in the area of figures were derived.

  • In Korea, Pbichim refers to a psychological state caused by emotional damages that can occur within close relationships. In this state, one might feel reluctant to express one's feelings directly to the other party. It is also possible that Pbichim transforms into anger. This study is aimed to define the term Pbichim as an indigenous psychological concept. In Korea, it is common to express one's feelings indirectly and read the other party's inward thoughts. Pbichim reflects those cultural aspects. In order to examine the representation of Pbichim in Korea, we developed a questionnaire consisting of 15 open-ended questions. The participants were 119 undergraduate and graduate students at Korea University, and the data was analyzed qualitatively. As a result, four different aspects of Pbichim (unsatisfied expectation, being ignored, being alienated, and power struggle) could be differentiated by the situation in which people are likely to present Pbichim. The personality traits of Pbichim, the way of relieving it, as well as positive and negative functions of Pbichim were also elicited. In addition, it was found that Pbichim (the concept that has been negatively perceived) has an important function in maintaining and improving an interpersonal relationship in Korea. Lastly, the importance of mind reading within a certain cultural context is discussed.

  • This study tries to illuminate the features and values of the Buddhist temple Palkyung by closely examining the forms, structures, and meanings of Tongdo-palkyung(通度八景) handed down at Tongdosa Temple, the best among Korea's Buddhist temples with its three treasures of Buddha, law of Buddha and Buddhist monks. The findings of this study can be summarized as the following. First of all, it reveals the meaning of the geographical name Yeongchuksan(靈鷲山), located to the west of Tongdosa, and a spectacular sight spread like an eagle's spread wings, as well as its location and spatial features. In particular, the arrangement features of a number of attached hermitages clearly show Yeongchuksan's world as being a temple with buddhist treasures. The multi-layered unfolding and centripetal intention of the scenery can be perceived through the shape of the Sshangryongnongju(雙龍弄珠形), around Tongdosa and the feature of the enclosed landscape encircling the steps of Hyeolcheo(穴處) Geumganggyedan. The substances and components of Tongdopalkyung include sound-based spectacles derived from Beoneumgu(梵音具) creating sounds related to religious rituals to enlighten and redeem mankind, such as Yeongji(影池: a holy pond with shadow reflections), drum sounds, and bell sounds along with physical features like pine trees, Dae(臺), waterfalls, Dongcheon (洞天), and a glow in the sky. On the other hand, Palkyung's geographical arrangements exhibit a circular spatial formation based on the main motif as Buddhist symbolism, beginning with the 'Gukjangsangseokpyo(國長生石標)' awakening the territoriality of Tongdosa and locating the first scene 'Mupunghansong(舞風寒松)' in its introductory area, with the features of water, bridge, pine grove, and Iljumun(gate) to stand for the influx. Six other scenes including 'Anyangdongdae(安養東臺)' are placed in the sacred precincts around Daeungjeon and Geumganggyedan while the glow of sunset at 'Danjoseong' just outside the domain closes the symbolic circular formation of the Tongdopalkyung, which coincides with the development of the Mandala figure symbolizing 'Gusanpalhae(九山八海)' centered in Sumisan(須彌山). What is more, Tongdopalkyung, while excluding primary scenic elements inside the temple, maximizes the domain of the mountain's entrance and the effects of the multi-layered mountain, mountain upon mountain, by intensifying the influx and centripetal qualities. The Tongdopalkyung analysis reveals the antithesis of four-coupled scenes conveying buddhist principles and thoughts on the basis of seasons, directions, space and time to display a narrative structural landscape when viewed from the temple's territoriality. Likewise, the characteristics and porch structures of Tongdopalkyung are tools and language of symbols to both externally strengthen the temple's territoriality and to internally, maximize the desires to the Land of Happiness as well as intensify religious wishes and the Mandala's multi-layered qualities through the meanings of time and space.
