  • In this study, we investigated and compared the types of analogy generation processes and the perceptions of analogy generation on saturated solution of fifth grade scientifically-gifted and general elementary students. After the instruction of self-generating analogies on 'saturated solution' concept for two classes, 12 scientifically-gifted and 8 general elementary students were interviewed to explore their analogy generation processes and the perceptions of the abilities required in the processes, the conditions of good analogies, and the advantages/disadvantages of analogy generation. The results revealed that their analogy generation processes were classified into three types. The scientifically-gifted students generated the analogies in more systematic and efficient ways and had better understanding of the important parts in the processes than the general elementary students. They also suggested more concrete and various ideas about the conditions of good analogies. Many scientifically-gifted and general elementary students thought that analogy generation would have positive influences on the developments of the cognitive aspects such as various higher-level thinking abilities and understanding of science concepts as well as the affective aspects such as science learning motivation and interest. Educational implications of these findings are discussed.

  • This study investigated the types of analogies generated by science-gifted students, mapping errors on the chromatography, and the perceptions on generating analogy. The subjects were science-gifted eighth-graders (N=68) enrolled at four gifted-education centers in Seoul. Analyses of the results revealed that most science-gifted students represented the analogies using verbal and pictorial forms based on concrete and everyday experiences, and they elaborately explained them including the functional attributes and the causal relationships of the target concept. Science-gifted students selected the analogies having rich similarities or similar structure and principle between the target concept and the analogy as the best of the self-generated analogies. And they used mainly their 'school life' as analogy materials. The results of the mapping test showed that many science-gifted students had mapping errors such as 'failure to map' and 'overmapping'. They were found to have the positive perceptions on generating analogy. The present study will provide the basic information to develop an instructional model in generating analogy in an education program for science-gifted students.

  • study investigated the effect of an instruction using generating analogy on scientific conceptual understanding, science learning motivation, attitude toward science instruction, and perception of instruction. Two classes of seventh graders at a middle school in Seoul were randomly assigned to the treatment group and the control group, and they were taught about the motion of molecules for 5 class hours. The instruction for treatment group was developed based on the Glynns Teaching-With-Analogy model. Two-way ANCOVA results revealed that the scores of the treatment group were significantly higher than those of the control group in the conception test. However, there was no significant difference between two groups in the science learning motivation test and the test on the attitude toward science instruction. Survey results on the students perception of instruction showed that generating analogy was hard for the greater part of students, and finding appropriate analog was the most difficult work. Educational implications are discussed.

  • In this study, we examined the characteristics of analogies generated by science-gifted students depending on the consideration of attributes and relationships in the processes of generating analogies and investigated the applicability of analogy-generating activities in science-gifted education programs. The analyses of the results revealed that the analogy-generating processes of science-gifted students were categorized into three kinds of patterns depending on the consideration of attributes and relationships of the target concept and the source analog. There are also some differences in the types of analogies generated and selected to be good, and in the proper mapping numbers by the patterns depending on the consideration of attributes and relationships. Most science-gifted students used the analogy-generating activities to other target concept, and recognized them to be useful. However, they had difficulties in selecting source analogs at the processes of generating analogy. These obtained in this study will help to explore a potential use of the analogy-generating activities in an effective education program for fostering the creativity of science-gifted students.

  • This study investigated the mapping errors induced in learning the concept of reaction rate with analogies, and compared these mapping errors by the analogy presentation types. Tenth graders (N=418) at a high school were assigned to the four groups by the target concepts and the analogy presentation types. The target concepts were 'concentration and reaction rate' and 'temperature and reaction rate'. In presenting analogy, the verbal and the verbal/pictorial analogs were used. After the students learned one of the analogs, a mapping test was administered. From the analysis, eight types of mapping errors were identified: overmapping, artificial mapping, failure to map, rash mapping, mismapping, mapping of a superficial feature, retention of a base feature, and impossible mapping. According to the analogy presentation types and the features of the target concepts, there were some differences in the frequencies of mapping errors. Educational implications of these findings are discussed.

  • The first purpose of this research is to investigate the functionalistic concept through the general consideration of Functionalism, and to study the art's aesthetic value of functionalistic expressionist artists implication and form in terms of architecture and product design. Secondly, it analyzes the implication and shape of Functionalism towards 'Art to Wear', which can be explained as a mixture of fashion and art. The results are as follows; First, functionalistic 'Art to Wear' of Mechanical Analogy appears to have futuristic inclination stressing the significance of geometric shapes and machine aesthetics. It uses new materials, and reduce an unnecessary work of art to convey more accurate, concrete and effective character of form. Secondly, functionalistic 'Art to Wear' of Organic Analogy regards natural elements as important to pursue the warm human nature. Also, it appears to be free and comforting forms of Functionalism through an organic silhouette. Thirdly, functionalistic 'Art to Wear' of Moral Analogy excludes excessive ornaments, and includes the implication of appropriate and purposive purity which serves for practical function.

  • For aerodynamic design of missile bodies of non-circular cross-section, the combination of the slender body theory and the cross-flow analogy can hardly be applied owing to the lack of experimental data. An alternative is to utilize the Euler solution in the design stage. For enhanced accuracy, however, an adequate viscous correction is necessary to the Euler solution. In this work, such a procedure is examined to compensate the viscous effect by utilizing the concept of proportionality factor in cross-flow analogy. Predictions of aerodynamic coefficients combining the Euler solution and the viscous correction via proportionality factor are made for a missile body of elliptic cross-section. Results indicate that the present approach can be adopted in designing missile bodies of non-circular cross-sections.

  • The purpose of this study was to observe five teachers' science classes and analyze the patterns of their analogies. To analyze the data, investigator triangulation was used, and the results were as follows: First, among the patterns of analogy used, expressions of similes and metaphors were utilized by all the teachers; teachers with over ten years' experience used adult's daily phrases, and teachers with under ten years' experience tended to use anthropomorphism. Regarding pictorial analogies, these manifested themselves in the sixth period, while teachers with over ten years' experience drew a simple picture about circulation of water, teachers with under one year's experience made additional materials for their analogy and they put an emphasis on the concept of the circulation itself. Teachers tended to use analogs according to their interests; teachers who majored in science education used pictorial analogies for further study. Second, the patterns emerging from the correspondence of the analogy manifested themselves in all the teachers equally, but they have no relation to the teacher's background. Third, routine analogy and artificial analogy appeared equally in consideration of degree of artificiality among the patterns of the analogies used. Regarding routine analogy, most teachers tended to look for analogs from things and experiences from themselves or their own backgrounds rather than those of the students. Regarding artificial analogies, teachers tended to purposely choose analogs to help students to understand; energetic teachers sometimes failed to choose appropriate analogs because they approached the topic with too much intensity. While a teacher who lacked experience and interest in science used many expressions of analogy, a teacher who felt some degree of constraint rarely used expressions of analogy. Fourth, most of the teachers used analogs familiar to their own experiences but students often found understanding these analogs difficult. Therefore, teachers need to make greater efforts to utilize analogs which are especially familiar to students when they attempt to explain science concepts.

  • This study investigated the effects of analyzing mapping errors on conceptual understanding, mapping understanding and perceptions of the instructions in learning chemistry concept with analogy. Seventh graders (N=121) at two middle schools were assigned to the comparison and the treatment groups, and were taught about 'states of matter and arrangement of molecules.' The students in the comparison group were taught in the Teaching-With-Analogy (TWA) model, while those in the treatment group Were taught in the instructional model that changed 'mapping similarity' and 'indicating difference' of the TWA model into 'analyzing mapping errors.' Analysis of the results revealed that the scores of the conception test and the mapping test for the treatment group were significantly higher than those far the comparison group regardless of field dependence-independence. It was also found that most students in the two groups positively perceived the instructions with analogy, but the students in the treatment group had difficulties in analyzing mapping errors, Educational implications are discussed.
