This study investigated the effect of small group discussion for science concept learning in cooperative learning environments that encourage verbal interaction with peers upon students' understanding of the concepts at the particulate level, application abilities, perceptions of students' negotiation, and communication apprehension. Two classes of 7th grade at a coed middle school were assigned to the control and the treatment groups. They were taught about change of states and motion of molecules for 7 class periods. Two-way ANCOVA results revealed that the scores of a conceptions test for the treatment group were significantly higher than those for the control group, and that the low-achievers in the treatment group performed better than those in the control group. However, the scores of two groups did not differ significantly in an application test. The perceptions of students' negotiation for the treatment group were more positive, but the scores of the communication apprehension for two groups were not significantly different.

Comics is sequential art. In comics, the story is developped by its sequential panels which have their own sizes and sites. Accordingly, comics is closer to 'space' art than text. The reading order in a page of comic book follows the human long-standing reading habit, and it is the same as that of textbook. When we read a korean comic book, our eyes run from left to right, and downward on the page. But some factors related to panels or comic structures can change the typical reading order. Meanwhile, breaking the typical reading order is easier in the "infinite canvas" by reason of unconstrained spatial composition. This paper introduces the factors that change the comic book readers' reading order and proposes a tablet PC comic book layout which includes an arbitrary reading path using interaction

The purpose of this study is improving the teachers' self-efficacy for pre-secondary music teachers. The research questions for this study were the improvement for teachers' self-efficacy for pre-secondary music teachers and the pre-secondary music teachers' perception about peer mentoring. In this study performed the interview and analyzed the in self-reflection journal in order to identify the improvement effect of teachers' self-efficacy and the participants' perception change in the peer mentoring. As the results from analyzing the change in participant's perception about peer mentoring the mentors had the opportunity to review previous learning contents and practice experiences while developing their team activity and for the mentees. Mentees said that they were given various help from the mentors' advices and their interactions and communication with mentors. From these results, it could identify that there was positive change in participant's perception about the peer mentoring. Based on these results, this study analyzed that it would need to require some chances for pre-secondary music teachers to be given some educational practice and field experience utilizing various teaching methods in order to improve their self-efficacy and the perception of peer mentoring.

This study examined the effects of Children's Social Development and Picture Representation Ability on Wordless Picture Books Activities. The study subjects were 30 children aged 3 years in K kindergarten: 15 in the experimental group and 15 in the comparative group. The experimental group was exposed to Wordless Picture Books Activities for 8 weeks. Image representation ability and social development test were conducted in both groups before and after the study. The after Wordless Picture Books Activities were found to be effective in linking various colors, detailed descriptions, harmonious spatial representations, various shapes, subject-related representations, uniqueness of representations, completeness of figure representations, and language representations. These study results are expected to validate the educational value of the wordless picture books meaningfully as teaching-learning materials in the field of early childhood education.

This study tried to investigate the differences between auditory preferences for a discrimination study of minimal pairs with the different onset and the same nucleus of a syllable on the basis of articulator-distance in case of Korean infants and toddlers. As a result we found a main effect for articulator-distance and age but not an effect according to the types of phonation especially in terms of tense. Former results are line with the previous studies having reported the order of consonants acquisition based on the places of articulation suggesting that more sensitive responses for the contiguous and different phonemes may lead earlier acquisition for the same place of articulation of the speech sounds. Specifically, bilabial soudns are followed by alveolar and palatal sounds in order. The latter results also showed that tense consonants got a high rate of recognition beside lax consonants according to the age and sex.

This study aims to figure out how the brand experience design elements works in the Shortform video-based branding through case analysis. The sense, feel, think, act, relate experience of Shortform video brand are provided through the implementation of specific experience design elements in the process of the creators expressing personality through social media channels and communicating and interacting with consumers. As a result, LIZIQI's food videos provided a brand identity as an 'Eastern gourmet' to consumers through the audiovisual stimulation of food in video, the cognitive reinforcement which is combined of identities and products, and the behavioral participation by web sites·electronic media. In addition, a strong brand relationship was established by sharing emotional ties using human factors and responsibility through co-branding. This can be extended to various Shortform video contents-based branding cases, and it will suggest a useful approach to the brand building strategy through strategic brand experience design elements.

Recently developed compilers perform some optimizations in order to speed up the execution time of source program. These optimizations require the transformation of the sequence of program statements. This transformation does not give any problems in a single-threaded program. However, the transformation gives some significant errors in a multi-threaded program. State-of-the-art model checkers such as Java-Pathfinder do not consider the transformation resulted in the optimization step in a compiler since they just consider a single memory model. In this paper, we describe a new technique which is based on SMT solver. The Java Memory Model Simulator based on SMT Solver can compute all possible output of given multi-thread program within one second which, in contrast, Traditional Java Memory Model Simulator takes one minute.

The purpose of this study was to investigate the effects of scientific program for gifted elementary students using metacognition on learning-flow and lingual interaction. For the purpose, the two classes for elementary science of P Institute for Gifted Education located in Pusan were assigned to experimental and control groups, respectively. The experimental and controls groups received eight sessions applying a program for scientifically gifted students using metacognition and same program without using it, respectively. The learning-flow test and the lingual interaction observed among students and between teacher and students pre and post program were compared and analyzed. The results shows that there was no significant difference between pretest and posttest in experimental group, indicating that learning-flow is not a construct obtained by short-term using of metacognition. For the lingual interactions, however, the amounts of conversation and the ratio of high level conversation in experimental group were 1.6 and 1.5 times higher than those in control group. This suggests that the lingual interaction may be varied among classes even with same experiments, by instruction method. The lingual interaction is not active in control group where the experimental results may be obtained easily only with sincere attitude while, in experimental group, questions using metacognition and providing intellectual stimulation is continuously presented, leading to high level of lingual interaction, therefore it is considered that the development of scientific program for gifted elementary students using these advantages is needed.
