For a profound understanding about the elementary students' scientific attitude, I have performed this study based on the students' opinion by the ethnographic interview and participant observation of science classes. I have analyzed the data by qualitative data analyzing method, and compared the analyzed results with analyzed results by the Likert's scaled as il questionnaire method. To perform this study, I selected one elementary school located in an agricultural village in Choong-Buk Province in Korea and studied four 5th grade students. Here, I present results of this study as follows. First, in ethnographic interview, all informants represented positive reaction to scientific curiosity. But, It is appeared that there are external curiosity and internal curiosity. Internal curiosity is more closely and positively related to problem solving skills. Second, all informants represented positive open-mindness expressing their own opinions actively and accepting other students' opinions. Students who had positive critical-mindness and voluntariness recorded high scores in science achievement. Third, scientific attitude analyzed by ethnographic methods didn't correspond with scientific attitude measured by Likert's scale in all cases. I presumed this discrepant result could come from subjects' different tendency on replying to questionnaire and students' own criterion.

The purpose of this study was to examine the effects on the effects of science lessons using six thinking hats techniques on creativity and science academic achievement. To verify the research problem, the subject of this study was fourth-grade students selected from four classes of an elementary school located in Busan. For ten weeks, the experimental group of 40 students was taught using the six thinking hats techniques. The comparative group also of 40 students, was taught in normal classes which used a Text-book. Children were given a creativity test and academic achievement test in science to measure the effects on six thinking hats techniques. Likert scales were used to gather students feedbacks on creativity and science academic achievement. Through these procedures, the following results were obtained: First, the six thinking hats techniques had a more effect on creativity than the normal classes, where a text-book was used. Second, the six thinking hats techniques could be seen to be effective in improving the student's academic achievements in science than the normal classes which used a Text-book. Third, the result of the student recognition investigation, we could know that the students showed lots of interest in the science lessons using six thinking hats techniques, and they were able to understand the scientific theories. As a result, the elementary science class with six thinking hats techniques had the effects of developing creativity and science academic achievement. It means the science class with six thinking hats techniques has potential possibilities and value to develop creativity and science academic achievement.

The purpose of this study was to examine the effects of science lessons using mind mapping on creativity and academic achievement in science. The subjects of this study were fifth-grade students selected from four classes of an elementary school located in Busan. For ten weeks, the experimental group of 40 students were taught using the mind mapping technique. The comparative group, also of 40 students, was taught in normal classes which used a standard text-book. Children were given a test on science processing skills and academic achievement in science to measure the effects of mind mapping. The Likert scales were used to gather student's feedback on creativity and academic achievement in science. Through these procedures, the following results were obtained: First, mind mapping had a greater effect on science processing skills than the normal classes, where a text-book was used. Second, mind mapping was effective in improving the student's academic achievements in science at a greater level than the normal classes where a text-book was used. Third, after viewing results of the Student Recognition Investigation, we found that the students showed a higher level of interest in science lessons that used mind mapping, and were better able to understand the scientific theories. As a result, the elementary science class with mind mapping developed greater science processing skills and saw higher academic achievement in science. We conclude that science classes that use mind mapping have the potential to develop better science processing skills and improve academic achievement in science.
The aim of this study is to investigate the change of science writing ability between pre and post-science writing which was written before and after argumentation activity and to show how argumentation influences the science writing ability. To fulfill this aim, eight 5th grade students were chosen from an elementary school. They were involved in the nine science writing themes which was compose of scientific contexts and social scientific contexts. Students' science works in argumentation and writing activity were collected and analysed based on four domains of framework for science writing ability: scientific thinking, logic, creativity and expression ability. The result of this study showed that the affirmative change of four domains of science writing ability on post-science writing written after argumentation was observed. Also, an affirmative change was observed in all of the scientific and social scientific themes. A lot of changes of the scientific writing ability were observed especially when the themes were familar to student. The degree of change depended on the level of the student, but overall it influenced all participating students with a positive improvement for their scientific writing ability. Students with high grade of academic achievement showed high improvement in science writing ability, but students who had low grade of academic achievement also showed a positive improvement in science writing ability.

In the 2015 revised curriculum, 'Integrated Science' was established to increase convergent thinking and designated as a common subject for all students to learn, regardless of career. In addition, the 2015 revised curriculum introduced 'competence' as a distinctive feature from the previous curriculum. In the 2015 revised curriculum, competencies are divided into core competencies of cross-curricular character and subject competencies based on academic knowledge and skills of the subject. The science curriculum contains five subject competencies: scientific thinking, scientific inquiry, scientific problem solving, scientific communication, scientific participation and life-long learning. However, the description of competencies in curriculum documents is insufficient, and experts' perceptions of competencies are not uniform. Therefore, this study examines the perceptions of science subjects in science high school teachers by deciding that comprehension of competencies should be preceded in order for competency-based education to be properly applied to school sites. First, we analyzed the relationship between achievement standards and subject competencies of integrated science through the operation of an expert working group with a high understanding of the integrated science achievement standards. Next, 31 high school science teachers examined the perception of the five subject competencies through a descriptive questionnaire. The semantic network analysis has been utilized to analyze the teachers' responses. The results of the analysis showed that the three curriculum competencies of scientific inquiry, scientific communication, scientific participation and life-long learning ability are similar to the definitions of teachers and curriculum documents, but in the case of scientific thinking and scientific problem solving, there are some gaps in perception and definition in curriculum documents. In addition, the results of the comprehensive analysis of teachers' perceptions on the five competencies show that the five curriculum competencies are more relevant than mutually exclusive or independent.
Background: Humidifier disinfectant exposure is an ongoing issue, and there is still considerable related controversy. Various approaches are needed to secure scientific evidence on the extent of the victims' damages and for the determination of appropriate compensation. Objectives: The purpose of this study was to assess the association between humidifier disinfectant (HD) use and academic achievement in Korean children. Methods: This study used data from the 8th Panel Study on Korean Children in 2015. For the final study, 1,598 cases were used. T-tests and multiple linear regression analyses were conducted to determine whether the use of humidifier disinfectant is a factor that affects academic ability. Results: Children in groups using humidifier disinfectant showed statistically significantly lower scores in all areas of language, including reading, speaking and writing, and statistically lower scores in all areas of mathematics, including counting, addition and subtraction. In the multiple regression analysis results, which control for the effects of various demographic/social variables, the use of humidifier disinfectants showed statistically significant beta coefficients (β: -0.357, p<0.001), negatively affecting children's language ability. As for the 'math' variable, which was created by combining counting, addition, and subtraction scores, the use of humidifier disinfectants as independent variables also showed statistically significant beta coefficients (β: -0.200, p<0.001), negatively affecting children's math ability. Conclusions: The results of the study showed that depending on whether or not humidifier disinfectants were used, there are differences in children's language abilities, such as reading, speaking, and writing, as well as in their mathematical abilities, such as counting, adding, and subtracting numbers. These findings are thought to serve as a scientific basis for extending the perspective from health effects to more diverse areas of demographic and social impact related to humidifier disinfectant damage and compensation.

The purpose of this study is to search effective assessments methods by using the Fusion model of Cognitive diagnosis theory. Attributes are skills or cognitive processes that are required to perform correctly on a particular item. After test items were developed, item's attributes were decided and Q-matrix about item's attributes was made. After testing, the result was analyzed according to gender and achievement level. The results of the analysis showed that students mastered 'Interpreting data' best, and 'synthesizing' worst among the five attributes. Female students showed higher ability than male students in 'recalling.' Students of high achievement level mastered more scientific attributes than students of low achievement level. Conventional assessments only provided a single summary score but Cognitive diagnosis modeling provided useful information by estimating individual knowledge states by assessing whether an examinee has mastered specific attributes measured by the science test. The skill profiles can offer a skill level of strong, weak, or mixed for each student for each skill. Therefore, the skill profiles will provide useful diagnostic information in addition to single overall scores.

The purpose of this study was to help elementary teachers to design systems for small group study to improve the efficiency of both teaching and learning in science education. This was done by examining how teachers form and manage a small group study, and by observing students' perceptions regarding small group study. For this study, an in-depth interview was conducted with 8 elementary teachers and 8 sixth grade elementary students chosen according to their levels of class participation and scientific achievement. The results showed that although elementary teachers preferred a group of 4 students, 6 students were randomly picked to form a group due to the physical aspects of the educational environment in most of the cases examined. It was also found that when the small group was composed of students with different personalities rather than according to their level of achievement, this better encouraged research activities and fostered scientific attitudes as compared to educating solely for the transference of scientific knowledge. On the elementary students' part, a change of perception on their new role and skills of interaction was also required. Elementary students preferred to compose small groups so that they resembled a group of close friends, and from their perspective, small group study was useful, interesting, time efficient, and helpful to each other in studying science.
This study mainly intended to investigate the relation between scientific inquiry and several entrance exam results of the gifted in earth science gifted program. The scientific inquiry was tested with their experiment designs. Entrance exams included achievement scores, creativity scores, problem solving, and oral test of high ability students. Student entrance scores were used to judge the level of students' competency in science. Recently students' ability of 'doing science' as measured by their designing experiments has been highly appreciated as a criteria of scientifically gifted students. One of the well known tests was Diet Cola Test developed by Fowler(1990). We used it as a test to figure out students' experiment design ability. We selected 22 gifted students in earth science. We compared their entrance test scores and Diet Cola Test results. Based on the comparison results we proposed several guideline of science education program for high ability students.
