This study was to find science high school students' perception about composing laboratory reports by grade. The instrument to survey the perception of them consisted of the perception about making a lab report, and the effect of compositing laboratory reports on the scientific concept understanding and the scientific inquiry ability. Subjects were 260 students of four science high schools in Seoul metropolitan city and Kyounggi province. Most of science high school students had a little positive perception about compositing lab reports, but they had very positive perception about the effects of it on the scientific concept understanding and scientific inquiry ability. There was the significant difference between grades, because the 10th grade students showed more positive perception toward compositing lab reports than the 11th graders(p<.05). The results suggested that different educational approaches and teaching strategies be needed for science high school students considering grades.

In this paper, both content analysis and Romey analysis were employed to analyze 'Basic Information Technology' textbooks in technical high schools. Not only was the content analysis employed to study the organization and contents of the textbooks, but also the Romey analysis was applied so as to determine inquisitive tendency on four factors - text, data, activity and evaluation. The results from content analysis showed that the total number of pages, reading material, the number of concepts introduced in each section, and the use of application software demonstrated a discrepancy among textbooks. Also, Romey analysis showed that while the section 'text' was written with relatively low inquiry tendency for its authoritative tone, two textbooks showed high inquisitive tendency for section 'activity'. Finally, based on the obtained results, the ways to improve 'Basic Information Technology' textbooks were proposed.

The purpose of this investigation is to: (1) to derive an improvement factor for inquiry-based simulated teaching-learning in pre-service teacher training programs, and pre-service teachers practice simulated teaching that reflect the improvement factor, (2) to analyze the difference in science intrinsic motivation according to science self-efficacy and inquiry-based simulated teaching-learning experience. To achieve these goals, we recruited five elementary and secondary teachers as experts to help us develop an improvement factor based on expert interviews. Subsequently, third-year pre-service teachers of a university of education participated in our analysis of differences in science intrinsic motivation, according to their level of science self-efficacy and experience with inquiry-based simulated teaching-learning. Our methodology involved applying the analytic hierarchy process to expert interviews to derive improvement factor for inquiry-based simulated teaching-learning, followed by a two-way ANOVA to identify significant differences in science intrinsic motivation between groups with varying levels of science self-efficacy. We also conducted post-analysis through MANOVA statements. The results of our study indicate that inquiry-based simulated teaching-learning can be improved through activities that foster digital literacy, ecological literacy, democratic citizenship, and scientific inquiry skills. Moreover, small group activities and student-centered teaching-learning approaches were found to be effective in developing core competencies and promoting science achievements. Specifically, pre-service teachers prepared a teaching-learning course plan and inquiry-based simulated teaching-learning in seventh-grade in the Earth and Space subject area. Pre-service teachers' science intrinsic motivation analyze significant differences in all levels of science self-efficacy before and after simulated teaching-learning and significant difference in the interaction effect between simulated teaching-learning and scientific self-efficacy. Particularly, group with low scientific self-efficacy, the difference in science intrinsic motivation according to simulated teaching-learning was most significant. Teachers' scientific self-efficacy and intrinsic motivation are needed to improve science achievement and affective domains of students in class. Therefore, this study contributes to suggest inquiry-based simulated teaching-learning reflecting school practices from the pre-service teacher curriculum.

The purpose of this study was to examine the effect of educational science magic program on creative problem solving ability, inquiry skill, and scientific attitude in elementary school science. For this, two classes of 3th grade were chosen in the J elementary school located in Suwon city as the experimental class(30 students) and the comparative class(30 students). The two groups were selected through a diagnostic examining program. Instruction using educational science magic program was applied to the experimental class. The results of this study were as follows. 1. the creative problem solving ability of the experimental class has statistically meaningful differences and improved, compared with the comparative class(p<.05). 2. the scientific inquiry skill was improved, but it has no meaningful difference statistically. However, science tasks applied educational science magic program had valuable significance to ability of measure(p<.05). 3. the scientific attitude score also was improved, but it has no meaningful difference statistically. However, science tasks applied educational science magic program had valuable significance to endurance(p<.05). 4. the results of survey showed that educational science magic program influence students' interests and concerns in science, class participation, pleasure in class, and comprehension of what is said in class positively. Therefore, a educational science magic program applied in this study might be useful to improve the creative problem solving ability, interests and concerns in science, class participation, pleasure in class, and comprehension of what is said in class.

It is necessary to realize in advance the lessons and knowhow about how to live, which humankind have developed, through learning to decrease the number of trial and error in our first trip to life. The big problem that present mathematical education is faced with is just only to place much importance on doing microscopic research ignoring macroscopic perspective, which results in the ineffectiveness of mathematics for contributing to life. The purpose of present study is to examine the way of living, classify methods of gaining an insight into life using macroscopic perspective, and develop a life model which can suggest a way of gaining an insight into life from external perspective. Also, this study explores a way of building a creative mathematical model for effective insight about life.

This study aims to find out the meaning of characters used in science textbooks by analyzing the roles of the characters on the 2009 revised science textbooks and the extracted sentences and see if there are indications referable to compiling future science textbooks by finding out where the characters are efficiently used and where supplement is needed. Target textbooks among those developed for the 2009 revised elementary school science textbooks are the first and second semester of the 4th-grade. Methods used include analysis on the roles of character-containing questions using character role analysis whose illustration analysis frame is more supplemented/adjusted than those used in the foregoing studies, analysis on character-containing questions using the existing analysis frame, analysis/survey on good cases and cases needing supplement through consultation with a science education expert, two teachers, etc. The result shows that among types of character roles, motivation and material provision are more used than experiment guide, experiment, and observation results. Result of analyzing in-textbook characters by field shows that life sphere is more used than free exploration, energy, material, and earth. Result of analyzing question types shows the order of expanding, anticipatory, transferable and personal questions and there were no reminiscent and evaluative questions. Based on the result of this study, indications on how to use in-science textbook characters more efficiently and developmentally are needed.

Science textbook is the most frequently used teaching material in elementary schools of the United States and Korea. Elementary science textbooks of the United States and Korea are analyzed to find out the educational objectives and characteristics of contents shown in textbooks. About 100 pages each in the first grade and fourth grade science textbooks each nations are selected randomly for educational objective analysis. Life science contents of 1st to 6th grade are analyzed from elementary science textbooks of the United States and Korea. The analyzed textbooks in Korea are 'Wise life,' an integrated subject with social studies and science, and 'science.' The analyzed elementary science textbooks of the United States are Harcourt Science, which is one of the frequently used textbooks. The educational objective framework used includes science knowledge, scientific inquiry, scientific attitude, STS, and philosophy and history of science. The results show science textbooks of the United States emphasize scientific knowledge more than scientific inquiry. Korean science textbooks emphasize scientific inquiry more than scientific knowledge. Elementary science textbooks of the United States present some life science topics redundantly and expose more difficult topics than Korean.
