In this study, we investigated the characteristics, the mapping understanding, the mapping errors, and the perceptions of student-generated analogies on the separation of mixtures using the sizes of particles by elementary school students' approaches to learning. Fourth graders (N=92) were selected and administered with the tests on the approaches to learning, self-generating analogies, and perception of self-generating analogies. The results revealed that the meaningful learners made more analogies, especially structural/functional, enriched, and higher systematic ones than the rote learners. However, there were little difference in students' approaches to learning in the subcategories of representation (verbal, pictorial, and verbal/pictorial), artificiality (artificial and everyday), and abstraction (abstract and concrete). The meaningful learners had deeper understanding of the analogy and fewer mapping errors than the rote learners. In addition, the numbers of the shared attributes included in student-generated analogies and the scores of the mapping understanding of the meaningful learners were significantly higher than those of the rote learners. Many students, regardless of students' approaches to learning, had positive perceptions of the self-generating analogies in various cognitive and motivational aspects. However, they also point out the various difficulties in the self-generating analogies as their disadvantages. Educational implications of these findings are discussed.

In this study, we investigated the characteristics of analogies generated by middle school students in the perspectives of the number of analogies, the mapping understanding, and the diversity and originality of analogs. We also compared the results by students' scientific creativity, field independence/dependence, and learning approach. Participants in this study were 250 9th graders in Seoul. The analyses of the results revealed that the students of higher scientific creativity generated more analogies, had a higher level of mapping understanding, and used more diverse and original sources. Field independent students had a higher level of mapping understanding. However, the other characteristics of analogies were not related to field independence/dependence. Meaningful understanding approach was related to all the characteristics of analogies, while rote learning approach was not related to any characteristics of analogies. Educational implications of these findings are discussed.

The purposes of this study were to identify the characteristics of students with different cognitive styles in the communication process according to the types of mathematical tasks and investigate the effects of their cognitive styles and types of mathematical tasks on their mathematical communication. For this, the investigator selected subjects according to the field dependent-field independent cognitive style by Witkin et al.(1977, p. 7). Mathematical tasks were developed in the areas of numbers and operations, regularity, and measurement according to the four types of Stein & Smith(1998, p. 269), which include the Memorization, Procedures without Connections, Procedures with Connections, and Doing Mathematics tasks. The selected students were divided into homogeneous groups according to their cognitive styles, and their communication processes according to the four types of mathematical tasks were observed through participation and videotaped. The videotapes were then transcribed and analyzed in protocols. The conclusions is that mathematical tasks of high cognitive level had positive effects on the activation of significant mathematical communication among the students and that differences in approaches to tasks according to their cognitive styles influenced their communicative activities in speaking and listening.

Objective : The purpose of this study is to provide basic information for professional education by investigating to learning styles and achievement goal of the first year students in the department of occupational therapy and physical therapy. Methods : 123 first year students of the department of occupational therapy and physical therapy filled out a questionnaire in Gyeongbuk and Kangwon Province. In this study, Kolb's Learning Styles and Elliot & Church's Achievement Goal were used, and to analyze, Pearson correlation, chi-square were used. Results : The results of the study were as follows. 'Accommodator' was the preferred learning type for students, while 'diverger' was not. Collage students differed from university students in learning styles. A mastery level was the preference in the academic goal types of the students. Male students received higher grades on performance approach goals than female and student of department of physical therapy received higher grades on performance avoidance goals than students in the department of occupational therapy. There is a coefficient of correlation between performance avoidance goal and converger learning type. Therefore, first year students in the department of occupational therapy were not differed from the department of physical therapy in academic achievement but collage students differed from university students in learning styles. Conclusion : From these results, we suggested some effective teaching/learning methods based on the mastery achievement goal. An educational approach is necessary for understanding of the students' individual learning styles and achievement goal characteristics are account for students' individual negative/positive characteristics.

The purpose of this study was to analyze elementary school students' interpretation of data characteristics by cognitive style. Participants were elementary students in sixth grade who can use integrated inquiry process skills. The students were divided into two groups, analytic cognitive style and wholistic cognitive style according to their response to Cognitive Style Analysis. They performed scientific interpretation of data activity. To collect data for this study, participants recorded the result on scientific interpretation of data activity paper and researcher recorded the situation on videotape and interviewed with participants after the end of interpretation of data to get additional data. And the findings of this study were as follows: First, the study analyzed interpretation of data characteristics by the operator regarding different situations of interpreting data according to cognitive style. For example, in the intermediate state, analytic-cognitive style students showed high achievement in identifying variables, and wholistic-cognitive style students were active in using prior knowledge to interpret data. Second, the result of analysis on the direction of interpreting data and preference for data types in interpreting data activities according to cognitive style are as follows: Wholistic-cognitive style students showed relatively high perception of information through the top-down approach. On the other hand, analytic-cognitive style students usually used the bottom-up approach gradually expanding detailed information to the scientific question-related answer and showed a preference data of the table type. Through the result, this study aimed to help establish a data interpretation strategy for learners to solve problems based on understanding of interpretation of data characteristics according to learners' cognitive style, and purposed the instruction design suggesting the data requiring various data interpretation strategies to develop learners' data interpretation ability.

The purpose of this study is to propose strategies of puzzle-based learning for Informatics gifted education through analyzing Informatics gifted elementary students' computational problem solving approaches in puzzle-based learning contexts. Six types of educational puzzles, which are constraints, optimization, probability, statistically speaking, pattern recognition, and strategy, were used in teaching 14 Informatics gifted students for 8 sessions. The results of pre and post test and each students' answers were analyzed to identify why students were not able to solve the puzzles. We also analysed what essential computational strategies are needed to solve each type of puzzles, and what students did not know in solving puzzle problems. We identified some problems caused by puzzle representation methods, and various students' intuitions that disturb puzzle solving. Also, we identified essential computational strategies to solve puzzles: backtracking, dynamic programming, abstraction, modeling, and reduction of big problem. However, students had difficulties in applying these strategies to solve their puzzle problems. We proposed the revised puzzle-based learning strategies, which is based on the improved problem representation, just-in-time cognitive feedbacks, and web-based learning system.

In this paper, we deal with the teaching of algebra based on patterns and generalization. The past algebra curriculum starts with letters(variables), algebraic expressions, and equations, but these formal approaching method has many difficulties in the school algebra. Therefore we insist the new algebraic approaches should be needed. In order to develop these instructions, we firstly investigate the relationship of patterns and algebra, the relationship of generalization and algebra, the steps of generalization from patterns and levels of difficulties. Next we look into the algebra instructions based arithmetic patterns, visual patterns and functional situations. We expect that these approaches help students learn algebra when they begin school algebra.

A usual approach of lyric poetry education emphasizes musicality of prosody that takes the format of singing lyric poem or reciting that involves reading with one's eyes and contemplating through one's consciousness, both with are quite remote from reality. In order to achieve an effective education, traditional lyric poetry education should focus on the recitation format that involves natural respiration. The current study specified theoretically the A study of contents in traditional Korean lyric poetry recitation. recitation. method through understanding rhythm and prosody that are basic principles of recitation. The study also attempted creating contents through three-dimentional image built on a theoretical foundation of systemic poetry recitation method in order to amplify the impression and creation of the traditional Korean lyric poetry. This was done as an effort to manifest an aesthetic nature of traditional lyric poetry and also as an effort to advance one more step in public understanding and appreciation of traditional poetry.

Given the potential of mobile applications to create new learning opportunities beyond the prevalent use of digital textbooks and Internet lectures, this study aims to derive types and themes of mobile application content that can be effectively integrated with the school curricula. Twenty primary school teachers participated in this study that examines teachers' perceptions about the advantages and disadvantages of printed and digital textbooks' modality, the advantages and disadvantages of mobile learning, and the themes relevant to develop mobile applications. Findings indicate that it is necessary to develop activity-centered applications for vertical use rather than theme-centered applications for horizontal use. In addition, while most ideas derived from teachers center on multimedia access, there was lack of ideas that leverage the affordances of mobile devices for collaborative interaction and location-awareness. Lastly, to promote the diffusion of mobile learning in school environments, this study suggests the need to overcome teachers' epistemology that perceives mobilization against inquiry activities.

Modern design has to be satisfied to user in various social class. Therefore a study of lifestyle is vary important as a basic of design. The logical starting point to grasp the user's needs is begun by consumer analysis. There are many methods of consumer analysis, In them, the study of lifestyle is extremely much used for understanding consumer who is classified with groups. Basic education of design have to teach knowledge and ability which is to be a groundwork for designer. The study of lifestyle is not a purpose itself but one of theoretical knowledge which is requested for design. By induding practical techniques and theory, theory can be achieved through practical techniques and the meaning of theory itself could be recalled. The value of this study is in the suggestion which is the way of approach to research and to study for oneself, by introduce the study through conceptual approach for lifestyle into basic design educational program. For the study of lifestyle, let students have the theoretical knowledge which is concept of lifestyle, modern social form, consumer culture, the way of using lifestyle and theorizing lifestyle, etc, And after, let students make teams for the study of lifestyle for oneself. Every team creates the subject and studies lifestyle of each social dass by the practical way such as Inquiry, observation and interview etc. As a result they have to make a report after the form of paper and let them have a presentation in each team. Students can understand lifestyle through this process not only theoretical but also practical and can be earned an ability for apply to business.
