  • This study investigated not only the existence of differently functioned item due to gender but also domain. In this study, the randomly selected data of TIMSS 2007, which consist of 681 male and 646 women, were analyzed. To detect differently functioned items, this study employed Raju method. For Raju method, three-parameter logistic model was selected. Signed and unsigned area between two item characteristic curve were measured within the real ability range. An item which was detected commonly SA and UA area in Raju method was defined as a differently functioned item. As a result of this study, six items among twenty seven items of mathematics in the TIMSS 2007 were differently functioned item. Five items among those six items, were in favor of boys and one item was in favor of girls. Number, Geometric Shapes and Measures, and Applying were in favor of boys. but Data Display, Reasoning were in favor of girls. The conclusion of this study was summarized as existing differently functioned items in TIMSS 2007 and difference between favorable domain based gender. Finally, it is desirable to consider the differently functioned items by relating those item content for improving the test reliability of TIMSS 2007.

  • Chinese Taipei won the first place at the mathematics achievement of TIMSS 2007. Especially, there was a significant difference in the percentage of correct answers between Chinese Taipei and Korea, and Chinese Taipei' percentage of correct answers was higher than Korea. This study compared the education system, mathematics instruction environment, and instructional activities of two countries. And for algebra, curriculum and textbooks were compared between two countries based on TIMSS 2007 framework. It was found that Chinese Taipei emphasized homework and test, and MCFL of that was low. Their textbook was formal, and induced the hasty abstraction, Also, some themes were introduced earlier than Korea and repeated across different grades.

  • The purposes of this study were to examine trends in Korean middle school students' attitudes toward science and the differences in boys' and girls' attitudes toward science as well as to analyze Korean middle school students' attitudes toward science compared to those in Singapore, Chinese-Taipei, Hong Kong, and Japan. In order to achieve these purposes, we analyzed students' survey data on self-confidence in science, interests in science, external motivation for science, and career preference for science collected from TIMSS 1995, TIMSS 1999, and TIMSS 2003. Korean students' interests in science and external motivation for science reduced in TIMSS 1999 and increased again in TIMSS 2003. The amount of change was greater in interests in science. On the other hand, self-confidence in science and career preference for science consistently declined from TIMSS 1995 to TIMSS 2003. Self-confidence in science among boys and girls was similar in TIMSS 1995 and 1999. But self-confidence of girls in science declined rapidly from TIMSS 1999 to 2003, while self-confidence of boys in science remained almost the same. Trends of interests in science were similar between boys and girls; they declined in TIMSS 1999 and increased again in TIMSS 2003. External motivation for science of both boys and girls increased, and the increase among girls was greater. The percentage of boys who wanted to have a job using science consistently declined from TIMSS 1999 to TIMSS 2003, while the percentage of girls declined in TIMSS 1999 and increased in TIMSS 2003 again. The results from an international comparison with other Asian countries having similar cultures showed that Korean students' self-confidence in science, career preference for science of middle school students was the lowest.

  • This study analyzed the characteristics of organization scheme and the levels of core concepts in science textbooks used in Korea, Singapore, and Taiwan, which have shown superior achievement according to the TIMSS 2007. Science textbooks in Korea clearly divide the fields of Energy, Matter, Biology, and Earth, presenting the fields in nearly equal proportion in each grade. In the case of Singapore, science textbooks take an integrated content approach, combining concepts from several fields under a single theme. Science textbooks in Taiwan present a single content field in each unit. Also, because each grade engages in a specific field intensively, there are many cases in which concepts related to a single field are studied in a single grade. In view of levels of core concepts, Singapore or Taiwan showed higher achievement than Korea in themes of 'Cell and their Functions', 'Ecosystems', and 'Human Health' under the TIMSS 2007 biology field. Singapore introduces core concepts for these themes in lower grades compared to Korea and presents them repeatedly in several grades. In Taiwan, there are many cases in which these core concepts are taught only once during the course of $3^{rd}$ to $8^{th}$ grade, but the explanations are presented at a level that is suitable to TIMSS 2007 assessment objectives. Considering the results of this analysis, there is a need to reconsider the division of content fields and methods of presenting core concepts in the science textbooks of Korea.

  • Gender differences have been given major attention in mathematics education in the context of pursuing gender equity in instructional and learning environment. It had been traditional belief that male students would outperform female students in mathematics, especially in the areas as geometry. This belief has been given doubts by cumulated empirical evidences that gender differences are gradually diminishing or even reversing its direction as time goes on. In this study, gender differences in geometry were explored using TIMSS 8th grade mathematics data administered in TIMSS 2003, 2007, and 2011, based on a cognitive diagnostic modeling(CDM) approach. Among various CDM models, the Fusion model was employed. The Fusion model has advantages over other CDM models in that it provides more detailed information about gender differences at the attribute level as well as item level and more mathematically tractable. The findings of this study show that Attribute 3(Three-dimensional Geometric Shapes) revealed statistically significant gender differences favoring male students in TIMSS 2003 and 2007, but did not show significant differences in TIMSS 2011, which provides an additional empirical evidence supporting the recent observation that gender gap is narrowing. In addition to the general trends in gender differences in geometry, this study also provided affluent information such as gender differences in attribute mastery profiles and gender differences in relative contributions of each attribute in solving a particular item. Based on the findings of the CDM approach exploring gender differences, instructional implications in geometry education are discussed.

  • The purpose of this study was to compare and analyze the elementary science curriculum of Finland, which ranked at the first place in the science domain of Programme for International Student Assessment (PISA), a comparative study on the academic achievements of OECD member nations, for three consecutive years and recorded a high national competitiveness index, and that of South Korea, thus providing information needed to develop curriculums and textbooks in the middle of occasional curriculum revisions and giving useful implications for the implementation of curriculum in the field of education in South Korea. The research findings were as follows: First, as for the science content areas based on the ratio of large area items according to the evaluation and analysis framework of TIMSS 2007, South Korea's ratio of life, chemistry, physics, and earth hardly showed fitness for TIMSS 2007 and exhibited equal distribution among the areas. In Finland, the ratio of life, chemistry, physical, and earth was similar to the fourth grade level of TIMSS 2007. The country showed differential distribution with life accounting for the highest percentage. Second, as for the cognitive domains, South Korea showed a high percentage in "Uses and Procedures of Tools" of "1. Knowing" and "Making Connections," "Comparison/Contrast/Classification," and "Uses of Models" of "2. Application." Finland recorded a high percentage in "Information Interpretation" of "2. Application." While South Korea focused on the uses and methods of scientific instruments during scientific activities, Finland made an approach with a focus on problems related to daily life such as the interpretation of information including reports and graphs from an interpretative perspective.
