  • This study was to examine the concepts using to explain evaporation and boiling in secondary school science textbooks developed in 6th and 7th science curriculum. The types of explanations were compared with maps represented the concepts relationships divided into middle and high schools, 6th and 7th curriculum, and subjects and chapters to find explanation diversity. The difference of explanations related to evaporation and boiling concepts was found in the school levels and subjects. There were few relationships between the main concepts of evaporation phenomena and those of boiling phenomena.

  • The purpose of this study was to compare and analyze the cognitive levels of 11th grade students and those required in high school chemistry I textbooks standardized by the 7th national education curriculum. For this study, the cognitive development stages of 456 11th grade students were surveyed using short-version GALT (group assessment of logical thinking). Furthermore, 15 basic concepts were extracted from the contents on water and air, 2 units in chemistry I order to analyze the cognitive levels necessary for understanding high school textbooks, using CAT (curriculum analysis taxonomy). The results showed that 52.5% of the surveyed 11th grade students reached the formal operational level, 28.3% transitional levels, and 19.5% concrete operational levels. 68.9% of the academic high school students and 6.6% of the technical high school students reached the formal operational levels, and the ratio of formation was very different in each logics. As a result of the analyzing the cognitive levels needed for understanding chemistry I textbook contents, in spite of a change in national education curriculum, there were no great change in cognitive levels required by scientific concept except some inquiry activities. The cognitive levels in high school chemistry I textbooks by the 7th national education curriculum appeared higher than the cognitive levels of 11th grade student, but cognitive levels of inquiry activities were similar to the cognitive levels of the students. Chemistry teachers thought of chemistry I textbooks by the 7th national education curriculum as desirable because scientific concepts were reduced and a lot of real life materials were adapted. However, they pointed out a problem of difference in contents levels compared with chemistry I textbooks because scientific concepts were greatly reduced in chemistry I textbooks. The cognitive levels required in chemistry I textbooks still appeared higher than those of the students. Consequently, various teaching and learning methods and materials will have to be developed to be suitable for the students' cognitive levels.

  • This study aimed to analyze the debate on the Elementary School Mathematics Contents in the new National Elementary Mathematics Curriculum developed in 2006. With this, the feature of the new National Mathematics Curriculum compared with the past 7th National Elementary Mathematics Curriculum was investigated. And the drafts on developing the new National Elementary Mathematics Curriculum were investigated as well. Three main controversies were identified. The first controversy was related to the item which had been dealt in middle school curriculum and moved to elementary school in the new National Mathematics Curriculum (e.g. equations, direct proportion and inverse proportion). The second one was related to the order of teaching fraction. The third one was related to the fact that problem solving became one of the five domains in Elementary School Mathematics Curriculum. Those controversies came from a basic belief on the ranges and depths of elementary school mathematics, didactical point of view, or thoughts on what should the content in the National Mathematics Curriculum be. The issues and suggestions that were discussed in this paper might serve to improve the National Mathematics Curriculum.
