This study examined the content diversity of seven authorized science textbooks by comparing the characteristics of the science concept description and the contents of inquiry activities in the "weight of objects" unit. For each textbook, the flow of concept description content and the uniqueness of the concept description process were analyzed, and the number of nodes and links and words with high connections were determined using language network analysis. In addition, for the inquiry activities described in each textbook, the inquiry subject, inquiry type, science process skill, and uniqueness were investigated. Results showed that the authorized textbooks displayed no more diversity than expected in their scientific concept description method or their inquiry activity composition. The learning elements, inclusion of subconcepts, and central words were similar for each textbook. The comparison of inquiry activities showed similarities in their contents, inquiry types, and scientific process skills. Specifically, these textbooks did not introduce any research topics or experimental methods that were absent in previous textbooks. However, despite the fact that the authorized textbook system was developed based on the same curriculum, some efforts were made to make use of its strengths. Since the sequence of subconcepts to explain the core contents differed across textbooks, this explanation process was divided into several types, and although the contents of inquiry activities were the same, the materials for inquiry activities were shown differently for each textbook to improve and overcome the difficulties in the existing experiments. These findings necessitate the continuation of efforts to utilize the strengths of certified textbooks.

The purpose of this study was to analyze elementary school teachers' implementation for the emphasis on the revision, major contents, teaching and learning method, and evaluation in the 2009 revised national science curriculum. To fulfill the purpose of this study we carried out a survey with 222 elementary school teachers. Main findings of this research were as follows: First, they highly agreed to the increase in class hours and the application of subject classroom, but they had a lower recognition for setting the subject groups. Second, the degree of necessity in discussion and STS was relatively high, but the degree of implementation in science writing, discussion and STEAM was low. Third, in teaching and learning method, they showed a high performance for mutual cooperation, student-led activities and communication, but, a low implementation for open inquiry and instruction considering individual differences. Fourth, in the evaluation of science learning, they showed a high implementation for evaluation based on achievement standards and one based on the understanding and application of basic concepts, but, a low implementation for the development of common evaluation tools. Fifth, it seemed that their recognition for amount, level and interest of science contents and inquiry activities was appropriate and positive.

The International Olympiad on Astronomy and Astrophysics (IOAA) initiated by the Thailand Astronomical Society in 2007 is an annual competition for high school students. One of its aim is to enhance the development of international exchange in the field of school education in astronomy and astrophysics. This paper first provides the overview of the IOAA in terms of key regulations based on its statutes, history and current status. Secondly, the published syllabus of the IOAA is used for content analysis according to subject areas regarding the exam questions of the IOAA in theoretical, observational and data analysis parts from 2007 to 2010. Also, a scientific inquiry framework is applied to the same questions for assessment based on scientific inquiry in the cognitive aspect with two sub-classes of scientific knowledge and scientific reasoning. Among a dozen astronomy subject areas listed on the syllabus, the theoretical part of the IOAA makes more frequent use of the Sun, the solar system, properties of stars, and concept of time. In content knowledge, a factor of scientific knowledge, the IOAA questions, especially in the theoretical part have a lesser degree in difficulty than the IAO (International Astronomy Olympiad) exam questions for the same period whose degree in difficulty is comparable to college level. With regard to scientific reasoning, the IOAA questions tend to involve convergent rather than divergent thinking. Lastly, in light of these findings, discussions are given on the outcome of Korean participation in the previous IOAAs and ways to help better in preparing Korean students for future astronomy Olympiads.

Among five types of the model textbook based on storytelling, the type of 'Inquiry into history of Mathematics' focuses on adapting the logic of mathematical discovery to the organization of mathematical contents. It enables students to recognize that mathematics has been developed by human needs and creativity while they are engaged in the story about knowledge formation. Moreover the textbook offers the context in which students are able to understand mathematical insights and logics hidden in the subject matter, so that they can reinvent and develop mathematical knowledge. In this study, we found the principles for development of the textbook based on storytelling for 'Inquiry into History of Mathematics' by analyzing the chapter about 'Complex number and Quadratic Equations' of the model textbook. The chapter was implemented in classroom environment and students' understanding of the subject matter and their perception on the textbook based on storytelling were surveyed before and after the implementation. The results showed the possibilities of adapting the textbook based on storytelling and we suggested some implications for further development.

The purpose of this study is to examine the change and appropriateness of inquiry tendency in elementary science textbooks by national curriculum period by comparing previous researches that reported Romey's Involvement Index in the science textbook and other subject textbooks. The results of the study are as follows: First, for the text index (T), the value of science textbooks by curriculum tends to continue to decline overall. The value of science textbook based on the 3rd curriculum is judged to be extremely inquiry oriented and the value of the textbooks based on the 2007 and 2015 revised curriculum are the values judged as somewhat authoritative textbook and as a textbook at the appropriate level of inquiry, respectively. There is no significant difference compared to the T values of other subject textbooks since the 2007 revised curriculum; Second, the index of figures and diagrams in the text (FD) of science textbooks also continues to decline by curriculum periods. In particular, the FD value of science textbook of the 2015 revised period is judged to be a authoritative textbook, which is lower than the value of other subject textbooks; Third, in the case of the activity index (A), it gradually decreases from the third curriculum to the 2015 revised curriculum, but it is judged as textbooks suitable for inquiry. However, after the 7th curriculum, the value of A is generally lower than those of other subject textbooks; Fourth, for the index of the questions at the ends of chapters (Q), the value of Q is reported to be extremely limited compared to the aforementioned three indices(T, FD and A), which may be mainly due to differences in the composition of science textbooks by curriculum period.

This study examined the instructional influences of MBL programs on elementary school students' science achievement, scientific inquiry skills, and science learning motivation. The perceptions of students and their teacher toward science classes using MBL programs were also examined. The subject of this study was sixty four 4th grade students from two classes. The experimental group engaged in science classes that applied MBL and the control group engaged in traditional science classes based on the textbook and experiment workbook. As results, there was no significant difference in academic achievement, scientific inquiry skills, however, were significantly higher for the experiment group compared to the control group. There was also significant difference in the relevance and confidence, the sub-categories of science learning motivation. In the analyses of students' perceptions toward science classes using MBL, students showed positive perceptions in aspects of interests of science classes, content comprehension, and convenience of experiments. The teacher also showed positive perceptions using MBL in elementary science classes. Educational implications of appling MBL in elementary science classes were discussed.
