In this study, we analyzed the analogies in the chemistry domain of 27 middle school science textbooks and 8 high school chemistry textbooks developed under the 2009 Revised National Curriculum. A total of 284 analogies (science, 143; chemistry, 141) were identified from the textbooks, which means that 8.11 analogies (science, 5.3; chemistry, 17.6) per textbook and 0.68 analogy (science, 0.66; chemistry, 0.70) per 10 pages were used on average. Compared with previous curricula that the number of analogies gradually increased, the use of analogy was found to be somewhat decreased in the 2009 Revised National Curriculum. The number of analogies found in each textbook considerably varied depending on course, unit, and publishing company. One hundred ninety one different kinds of analogies were used, among which 38(19.9%) were used over twice. Further analyses of the types of analogies indicated that verbal and pictorial analogy, analogy with abstract target and concrete analog, and enriched analogy were frequently used. However, the term 'analogy' and the description about the limitation of the analogy were rarely mentioned. Artificial analogy, teacher-centered analogy, and analogy with low systematicity were also found to be frequently used. Educational implications of these findings are discussed.

In this study, the texts of science textbooks of the past 20 years were collected in order to systematically carry out researches on scientific languages and scientific terms that have not been noticed in science education. We have collected all the science textbooks from elementary school to high school in the 6th curriculum, the 7th curriculum, and the 2009 revised curriculum, and constructed a corpus comprising of 132 textbooks in total. Sequentially, a raw corpus, a morphological annotated corpus, and a semantic annotated corpus of science terms, were constructed. The final constructed science textbook corpus was named K-STeC (Korean Science Textbook Corpus). K-STeC is a semantic annotated corpus with semantic classification and classification of scientific terms, together with meta information of bibliographic information such as curriculum, subject, grade, and publisher, location information such as chapter, section, lesson, page, and sentence, and structure information such as main, inquiry activities, reference materials, and titles. Throughout the three-year study period, a new research method was created by integrating the know-how of the three fields of linguistic informatics, computer science and science education, and a large number of experts were put in to produce labor-intensive results. This paper introduces new research methodologies and outcomes by looking at the whole research process and methods, and discusses the possibility of future development of scientific language research and how to use the results.

The effects of education utilizing history of science on science achievement and attitudes of the ninth grade students were investigated according to their achievement level, along with the development of teaching and ;earning materials. A total of 144 ninth grade students were divided into the experiment and control group. Instructing students using history of science was performed in the experiment group, while conventional instruction was used in the control group. The scores of both pre-test and post-test were estimated by ANCOVA. Instructions applying history of science were more effective in increasing the students' science achievement and attitude than conventional instructions. In particular, the former enhanced the achievements of the upper-level students, more than it did for the middle and lower-level students. In addition, using history of science showed a better effect on higher and middle-level students, in improving their attitudes toward science, than it did for lower-level students. This study suggests that the instruction utilizing history of science should be designed based on the students' achievement level, and that various teaching and learning materials related to the instruction were helpful.

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.

The purpose of this study is to examine what aspects of mathematical activities in elementary school mathematics textbooks pre-service school teachers pay attention to in the process of didactic transposition. To do this, the third grade students of the College of Education were asked to analyze the activities of the elementary mathematics textbooks and then select a lesson activities as needed to modify or supplement the activities. As a result of the study, in the process of revising textbook activities for mathematics lessons, pre-service teachers pay attention to whether the textbook activities provide concrete activities, whether they induce student motivation, and whether there is overlap between classes activities. For the didactic transposition of textbook activities for mathematics lessons, pre-service teachers were able to comprehensively utilize relevant curriculum documents such as national curriculum and teachers' manual for checking the goals and achievement standards and lesson objectives.
