  • In this study, the analogies in the chemistry domain of middle school science textbooks developed under the 2007 revised National Curriculum were analyzed. A total of 235 analogies were found in 27 middle school science textbooks analysed, which means that one analogy per 10 pages was used on average. The number of analogies found in each textbook considerably varied depending on both publishing company and chemistry domain. Functional analogies, verbal and pictorial analogies, analogies with abstract target and concrete analog, enriched analogies, everyday contexts analogies, student-centered analogies, and analogies with low systematicity were frequently used. On presenting the analogies in the textbooks, the term analogy and description about the limitations of the analogies were rarely mentioned. In comparison with the analogies in the science textbooks developed under the 7th National Curriculum, the frequency of analogies per page was increased. There were positive changes in the aspects of representation, extent of mapping and artificiality. No differences, however, were found in the patterns of the other aspects.

  • In this study, the analogies on saturated solution generated by elementary school teachers were analyzed in their numbers, materials, and types aspects. The results were also compared with those of general and science-gifted elementary students. A test on the self-generating analogies on the target concept was administered to 111 elementary school teachers, 60 fifth graders at four science-gifted education institutes and 91 fifth graders at three elementary schools. The results revealed that the teachers made more analogies than the general and science-gifted students. In general, both the teachers and the students tended to make the analogies using the materials in family, riding, digestive, and school situations. However, there were a little difference between the teachers and the students in the cases of the analogies using other situations including body/physical activity. Similarly to the cases of the students, the teachers made more functional analogies than structural or structural/functional ones and did more concrete ones than abstract ones. However, they made more verbal, artificial, and enriched analogies than the students. They also made more highly systematic analogies than the general students, and did less ones than the science-gifted students. Educational implications of these findings are discussed.

  • The purpose of this study is to research the effect of using analogies in high school earth science classes. According to the usage of TWA model, three types of teaching strategies were developed: text developer-generated, teacher-generated, and student-generated analogies. The model described in this paper began with a task analysis of highschool science textbooks for grade 10 to identify how the textbook authors used analogies to explain plate tectonics concepts. In this study, 210 students were sampled from first graders of high school. After 7 classes, the consciousness of students was investigated with questionnaires. The results are as follows: 1. Many plate-tectonics analogies are used in high school science textbooks (total 25). Teachers and authors construct effective analogies to help students build on their relevant knowledge by applying it to new knowledge acquired from textbooks. 2. Analysis of the data indicate that instruction using student-generated analogies was more effective than others. But in the class in conveying complicated concepts (ex. transform fault), teacher-generated instruction was effective. Teachers need to be aware of the weakness of using analogies in order to select the most appropriate analogies. 3. Making analogies in general, as well as using analogies have systematic steps. Analogies should be used after considering student's preconception, teacher's consciousness and text author's intention to use analogies as powerful instructional tools.

  • The purpose of this study was to analyze the use of analogies in high school science textbooks in explaining abstract science concepts. For this study, the analogies used in high school science textbooks of the 7th science curriculum were analyzed. The analogies were classified into the six following types: the nature of shared attributes, representation, analogy/target abstraction, number of analogies, with and without specified use of analogy, and casual relations. A total of 189 analogies were found in the 7th science textbooks. This means that 16.9 analogies were used for each book. In analyzing the analogies, we found some analogies were appropriate, while others were ambiguous and inadequate in explaining the various science concepts. The number of analogies used varied considerably according to the publishing company and the science domain. For more effective understanding of various science concepts, it is necessary to develop more analogies and research the application of analogy.

  • Research studies have shown that phonological awareness focused analogies and anagrams can be used as an effective game-based teaching instruction. However, previous studies used analogies and anagrams as separate instructional tools, especially in EFL-related situations. There has been no vocabulary learning in analogies/anagrams instruction provided, nor has there been usage of an integrated workbook for 'vocabulary learning and analogies/anagrams'. This study examined the effect on learners' vocabulary acquisition scores when a truly phonological awareness integrated 'analogies/anagrams and vocabulary learning' workbook was used as an instructional practice workbook. The results show that the phonological awareness integrated instruction significantly increased learners' vocabulary acquisition scores among 40 college students with minimal or basic level of English proficiency.

  • In this study, we investigated pre-service science teachers' design for lessons using analogies in the perspectives of PCK. Three pre-service science teachers at a college of education in Seoul participated in this study. After the workshop of instructional analogies in science education, they practiced lessons using analogies in teaching practices. We observed their lessons and collected all of the teaching-learning materials. Semi-structured interviews were also conducted. The analyses of the results reveal that they dealt with mapping and unshared attribute only when using main analogies in their lessons and these processes were teacher-centered. There were some cases where they failed to adequately deal with analogies including concepts beyond the curriculum. When dealing with unshared attributes, they did not tend to accept students' opinions although they thought that unshared attributes are strongly related to misconceptions. Their understanding of assessment using analogies was not high. Assessment was relatively well done when they use student-centered analogies such as physical analogies or role-playing analogies. On the bases of the results, we suggest some educational implications for pre-service science teacher education.

  • The purpose of the study was to investigate middle school students' comprehension about analogies for explaining conceps related to electric current. For the study, 14 seventh grade students and 14 eighth grade students were sampled, and they were divided into two group, one group for implementing pictorial analogies, the other for analogies in words. The subjects are academically high achievers. The conclusion of this study is that the middle school students' comprehension about analogies of electric current is low. So the author of this study suggests that conditions as analog and context of analogy usage should be considered for the use of the analogies.

  • The purpose of this study was to analyze the analogies used in elementary science textbooks. For this, the analogies were classified into the following criteria : analogy-related contents included in elementary science text-books, types of representation style, and the role of analogy. The results of this study were as follows : the total of analogies was 154 in the 6th and 166 in the 7th curriculum. Most of them were expressed in textbooks and experimental texts. More structural/functional, verbal/pictorial, concrete/concrete, concrete/abstract, simple and enriched analogies were included in the science textbooks of the 7th than those of the 6th. Most of them took the role as an aid to understanding. According to the domain of science content, energy, material, life domains were increased in the 7th than the 6th, with the exception of the earth science domain. The ratio of used analogies in the life domain was higher than the others, and in the material domain it was the lowest. From these results, it can be said that, in order to help students' understanding, further research into the application of analogies is needed.

  • In this study, students' understanding of the analogies used for chemical concepts in science textbooks, misconceptions induced by the analogy, and the factors affecting conceptual understanding were investigated. In addition to the tests of field independency and logical thinking ability, tests of students' understanding of concepts and analogies on three states of matter, pressure-volume relation, molecular motion, and changing state depending upon energy were administered. The results revealed that half of the subjects understood the analogies differently from the textbook writers' intention and that students' conceptual understanding was significantly correlated with the degree of understanding on corresponding analogies, field independency, logical thinking ability, and prior achievement of science. The results of analyzing the direct and indirect effects of each variable on conceptual understanding showed that the direct effect of prior achievement was significant and that field independency and logical thinking ability had indirect effects through understanding of analogies and prior achievement of science. The limitations and implications of using analogies in science education were discussed on the basis of the results.
