The purpose of this study was to identify the scientists' abductive reasoning in three stages of hypothetical-deductive inquiry process; generating hypothesis, designing, and interpreting data and to suggest new analytic coding frames on abductive reasoning in each of the stages. For this purpose, the interview protocols collected through in-depth interviews with eight scientists were analyzed by the early frame with sub-elements derived from the literature reviews. The need of a new frame of analysis beyond the previously established elements arose from the result of this analysis because the processes of abductive reasoning were found in all three stages. Based on scientists' interview data, this study then designed a new frame of analytic coding frames on the abductive reasoning in each of the stages. The content validity index from four experts was 0.90, and these frames showed a good fit to analyze the scientists' real process of abduction in three stages of hypothetical-deductive inquiry process.

The purpose of this study is to suggest improvements in the science concepts and inquiry activities presented in the earth science section in the 2015 revised curriculum elementary science textbooks. For this study, two science educator and three elementary school teachers developed a survey questionnaire to investigate science concepts, inquiry activities, and suggest improvements. The survey was conducted two times, and 30 elementary school teachers and three earth science professors (geology, meteorology, astronomy) participated in the survey. As a result, it was investigated that eight concepts in the solid section, three concepts in the fluid section, and one concept in universe and integration section contained misconceptions. It was investigated that the content of inquiry activity needs to be supplemented, with seven elements in solid section, three elements in fluid section, and one in the universe and integration section. According to the research results, if the textbook is revised, it is necessary to accurately confirm the science concepts or content of inquiry activities. Also in the case of science concepts presented in textbooks, it will be necessary to consider not only the scope and sequence of contents but also the process of learning progression.

This study focused on the use of student assessment activities to investigate the impact on reflective thinking in Argument-based Inquiry. The participants of the study were 166 10th grade students (six classes). Over one semester, students participated in five ABI programs that we developed. The experimental group (84 students) was taught Argument-Based Inquiry with students' self and peer assessment activities. The comparative group (82 students) was taught without the activities. We analyzed students' reflective writing to investigate how the student assessment activities influenced the students' reflective thinking. We also used the interviews and surveys to examine the validity of student assessment activities. According to analysis of the reflective writing, the experimental group had a significantly higher mean score than the comparative group in the 3rd and 5th writing. The ratio of students who showed a metacognitive level of reflection with regard to analysis of inquiry process, understanding of learning, and change of thinking increased in both groups, but the experimental group's ratio was higher than the comparative group's. The result of analysis of the reflective practice showed that the ratio of the experimental group's students who reached the metacognitive level of reflection in their writing increased, while the comparative group's decreased. Therefore, we conclude that student assessment activities can create a learning environment that facilitates student participation, increases the students' engagement in the learning process, and can be used as a tool to scaffold learning.

The purpose of this study is to develop the evaluation criteria for students' research reports on online science inquiry problems that promote thinking abilities. The steps of developing the evaluation criteria are as follows; First, based on previous study results and literature review, the evaluation categories of the science inquiry contents were determined: 1) knowledge, 2) logical and analytical thinking, 3) critical thinking, 4) science process skills, 5) problem-solving, and 6) creative thinking. Second, evaluation criteria are developed according to the following steps: 1) define each category, 2) identify sub-category, 3) develop evaluation criteria for all categories that could serve as guidelines in the development of scoring rubrics, and 4) expert validation processes were performed. Finally, the usability test for these evaluation categories and criteria were done by being applied to the development of real scoring rubrics for 24 problems included in e-learning contents. Then the users' feedbacks were filed and the implications of this study were discussed.

The purpose of this study is to acquire teaching insights for improving scientific literacy by analyzing the effects of scientific communication skills, science process skills, and logical thinking skills of elementary school students on academic achievement level. The participants are 64, sixth grade elementary school students. Survey materials include the results of Scientific Communication Skill Test (SCST), Test of Science Process Skills (TSPS), Group Assessment of Logical Thinking (GALT), multiple choice test & short answer test, descriptive answer test on science, and academic achievement level test on all subjects. Based on these data, the study analyzed the relationships of science process skills, logical thinking skills, and scientific communication skills, and each category's effect on academic achievement level. Furthermore, under the assumption that scientific communication skills are affected by science process skills and logical thinking skills and directly influence the academic level, the research discovered three types of correlations as a structural model. The results show that there are considerable correlations in scientific communication skills, science process skills, and logical thinking skills. Also, these three abilities have meaningful correlations with learner's writing and descriptive question level on science curriculum and overall academic achievement level; the level of correlation differ a bit by subcategory factors. In conclusion, setting the model, science process skills and logical thinking skills influence scientific communication skill, and the skill directly influences the learner's academic level. Further analysis of the results show that scientific communication skill influences the academic achievement level of all subjects the most.

This study focused on the use of peer assessment activities to investigate its the impact on students' argumentation skills in argument-based inquiry. The participants of the study were 106 10th grade students (four classes). Two classes were assigned to the experimental group, and the other two classes were assigned to the comparative group. The experimental group was taught argument-based inquiry through the application of peer assessment activities. The comparative group was taught argument-based inquiry without peer assessments. At the claim and evidence stage, students were asked to evaluate whether peers' claims fit with the evidence and whether peers' explanation of the evidences validity was sufficient. The quality of argumentation used in the students' writing was different in each group. According to the analysis of the summary writing test, the results showed that the experimental group had a significantly higher mean score than the comparative group in argumentation components, including evidence and warrant/backing. In addition, the experimental group used better multimodal representation including explanation of evidence than the comparative group. The findings showed that argument-based inquiry applying peer assessment activities had an effect on the argumentation skills in students' writing.

In this study, the test that were used in entrance examination for chemistry class in a Science-Gifted Education Center for middle school students were analyzed by using criteria for identification and measurement of scientific giftedness and a classical test theory. The result of analysis exhibited that most of problems measured more than two elements of scientific giftedness and required applications of scientific knowledge of middle school level to solve problems. In the analysis of sub-elements of scientific giftedness, originality, fluency in creativity and finding problems/formulating hypothesis, planning inquiry, interpreting data in science process skills were dominant while drawing conclusion and generalization processes were lacking. In correlation analysis between total score and each type of problems, total score was most influenced by the problems measuring science inquiry linked with scientific knowledge. Item difficulty is moderately high and item discrimination is moderate.

In this study, we developed analogical experimental activities to foster scientific creativity in inquiry learning and applied them to 7th grade science-gifted students. The influences of inquiry learning-based analogical experiments were investigated with respect to the experimental design processes. We classified the patterns of experimental design processes by creative thinking processes and analyzed performance levels by the elements of experimental design processes. The students' experimental design processes were categorized into three kinds of patterns such as reinitiated motion, backward-divergent motion and stationary motion. Those belonging to the reinitiated motion performed precise experimental design from new perspectives by identifying the mapping in depth and considering the elements of experimental design processes. In the case of the backward-divergent motion, they shifted their positions to new directions, but the concreteness of experimental design was insufficient due to the lack of mapping or considering the elements. In the type of stationary motion, maintaining their previous positions, they showed less performance of experimental design without considering the elements sufficiently. Educational implication of these findings are discussed.

The purpose of this study is to analyze common inquiry tasks of middle school history textbooks and find out it's implications on teacher librarians' educational information services. There are 84 common inquiry tasks according to examinations of inquiry tasks related to world history in 18 kinds of middle school history textbooks. Results of the analysis show that almost all of common inquiry tasks of world history make middle school students who should resolve them research the pictures and reading materials included in the textbooks individually and verbalize under the information literacy process. Compared with information literacy process of the "Library and Information Skills" for middle schools, the First step of task definition and figuring out information needs and the Third step of representation of information are being implemented. For this reason, teacher librarian could reduce history studies teachers' burden of running the class and promote students' inquiry activities by teaching skills of information analysis and interpretation, synthesis and organization and evaluation of their information literacy process and results.
