  • The purpose of this research was to investigate ways of restructuring key competencies (KCs) in preparation for a revision of Korean science curriculum. Recently a number of countries have reformed their curricular using competencies as a key element because they believe that competencies-based curriculum helps students build up the necessary skills to live in the future society. Through literature reviews, in-depth interviews with experts and teachers, expert meetings, Delphi methods, and surveys with teachers, three major categories of KCs emerged as follows: Character competencies, Intellectual competencies, and Social competencies. For each major category, its definition, characteristics and teachers' comments are discussed. The specific components of KCs for each major category and implementing KCs should be determined at the subject- and teacher-level based on teacher professionalism. In the conclusion section, we suggested a couple of important points that deserve readers' attention when we reconstruct science curriculum by incorporating three major categories of KCs. When we develop a science curriculum in the future, we need to include three major categories of KCs, and set up KCs as a minimum set of goals for all students. We need to remember that specific components of KCs for each major category and linkage among KCs may vary depending on science topics and objectives.

  • TIMSS (Trends in International Mathematics and Science Study) aims to produce reliable and internationally comparable indicators of student achievement. The TIMSS science achievement scale summarizes student performance on test items designed to measure a wide range of student knowledge and proficiency. This study analyzed Korean middle school students' science achievement at the advanced and high international benchmarks of the four benchmark levels of the benchmarks classified in TIMSS 2003 in light of science content areas (physics, chemistry, biology, earth science, and environmental science) and item characteristics. The average percent correct on items at the advanced benchmark by Korean students was highest in physics followed by earth science, biology, chemistry, and environmental science, whereas internationally the order was earth science, chemistry, biology, physics and lastly environmental science. Korean students performed relatively better in physics yet somewhat worse in chemistry than other top-performing countries. According to item analysis, Korean students reaching the advanced international benchmark understood some fundamentals of scientific investigation, but demonstrated weakness in written explanations of scientific principles, abstract science concept comprehension, and application of scientific concepts to solve quantitative problems. In addition, Korean students reaching the high international benchmark demonstrated relative weak conceptual understanding of ecology compared with other countries.

  • 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.

  • The purpose of this study was to identify STEAM education program fit for club activities in consideration of the present curriculum and investigate its effect on science club students' self-efficacy and attitude toward science by applying it to science club students. In consideration of such chapters as 'Solar System' and 'Exosphere and Space Development' in the 2009 Revised Curriculum, this study developed a STEAM education program related to the observation of the solar system and the measurement of a distance of the stars in consideration of the present curriculum. For this study we selected 14 science club students in H Middle School, located in G Province and applied a 7 weeks' program to them. To find out change in their self-efficacy and attitude toward science, this study conducted tests of self-efficacy and attitude toward science for a single group before and after introducing this program and analyzed the results. The results of this study could be summarized as below. Firstly, science club activities with this STEAM education program applied improved students' self-efficacy significantly. Secondly, there was a significant difference found in students' attitude toward science through science club activities with this STEAM education program applied as they showed higher scores in the attitude toward science in the posttest than the pretest. Lastly, despite a research limit that this science inquiry program was conducted for a short period of time, this program was found to have positive effect on the improvement of students' self-efficacy and attitude toward science.

  • This study analyzed content on sustainable development in the middle school science curriculum of 2007-Revised. Analyses criteria were developed based on literature reviews. The analyses showed that among 25 units, nine of them dealt with the topics and issues on sustainable development. However, the content had too much partiality for biology and earth science, lacking integration with other areas of science. Results of this study suggest the need for developing systemized teaching material on sustainable development that can be incorporated in the science curriculum by pursuing the following tasks: First, the educational goal of sustainable development and its need should be mentioned in the science curriculum. Second, the class content, themes, objectives, teaching-earning programs on sustainable development should be formulated. Third, within the science curriculum, the content should deal with topics beyond natural or environmental issues, to issues such as economical and socio-political so as to bring better understanding of the concepts related to sustainable development.

  • In this research, we investigated the historical development and ways of improvement of the teacher employment test (TET, hereafter) in Korea. This paper consists of three parts. The first part details the secondary science teacher education system in Korea. The second part elaborates upon the development of the TET since 1990's. The third part provides conclusion by addressing ways to improve science teacher education and employment systems in Korea. After all, the keen competition for teacher education and the demanding entry test ensure that secondary science teachers are selected from a pool of candidates with high academic achievement. Korean teacher employment system in general places more weight on subject knowledge. Although we cannot simply conclude that Korean science teachers must have profound knowledge in the subject matter and are competent in pedagogy, it stands to reason that the teachers could be more competent in performing their roles than those of many western countries with an acute shortage of teachers. We also suggested future directions and ways of improvement regarding teacher education and the TET in Korea.
