  • Inquiry-centered education is important in science education, but in the actual education field, scientific research is being done in a uniform manner due to realistic difficulties. In this study, we use RS (Reverse Science) as a secondary chemistry class to provide opportunities for students to engage in inquiry learning and scientific thinking through process-oriented activities. In this study, we developed and applied it to explore the effects on the scientific inquiry abilities of middle school students and checked the students' perception of it. For the application of the program, 128 students were selected from 6 classes of the 2nd grade in D district middle school, 64 from the experimental group and 64 from the comparative group. The experimental group taught RSP-based the chemistry inquiry programs and the comparative group taught instructor-led classes and verification experiments on the same topic over the seventh hour with three themes. In addition, we analyzed the results of the pre- and post-test by using the science inquiry ability test, and discussed the effects of the program based on the students' perceptions through class observation, student activity area, questionnaire and interview. As a result, the class using the program showed statistically significant changes in the science inquiry ability of secondary school students. Specifically, the experimental group was found to be significant in its prediction among the subcomponents of basic exploration ability compared to the comparative group. The differences have also been shown to be significant in terms of data translation, hypothesis setup and variable control, which are subcomponents of integrated exploration capabilities (p <. 05). In addition, students became interested in the process of creating the theory of science, and were highly interested in collaborating with their friends. It also provided students with opportunities to experience scientific thinking through process-oriented inquiry. Finally, based on the positive impact of the RSP-based chemistry inquiry program on students, we were able to identify the potential use of the program.

  • The purpose of this research was to identify the components of scaffolding in open inquiry and to explore the functions of teachers' scaffolding, which is necessary to support students' open inquiry. In order to identify scaffolding components, at first, we conducted a survey using a questionnaire on what students think about open inquiry on 110 students who performed open inquiry in two middle schools, and then carried out factor analysis based on the survey results. It was attempted to investigate students' perception through focus group interviews corresponding to scaffolding components that were identified through factor analysis. Also, we examined teachers' empirical view of scaffolding functions in open inquiry through in-depth interviews with four teachers. The results of exploratory factor analysis revealed that there were five scaffolding components of open inquiry: motivation, planning, strategy, environment and participation. The results of focus group interviews showed that students experienced difficulties in planning, strategy, environment and participation components, except for motivation component. In particular, students asked for support to strengthen the participation component, which means recognizing their role, active participation and collaboration with peers. Meanwhile, the results of in-depth interviews with teachers showed that teachers' empirical views of scaffolding function in open inquiry were categorized as cognitive (conceptual, metacognitive), emotional (motivational, arbitrative) and strategic. Interviewed teachers preferred the strategic scaffolding and cognitive scaffolding to the emotional scaffolding. Based on the results, we also discussed the implications for performing open inquiry effectively.

  • The knowledge and information processing competence is one of the essential competencies in an information-oriented society which is highly related to science education. The purpose of this study is to investigate middle school students' difficulties in science inquiry activity in view of the knowledge and information processing competence. Collection, processing, and application of information are extracted as common elements of the knowledge and information processing competence through literature search. Data were obtained from eight students of a middle school in Seoul for five months and were analyzed based on constant comparative method to extract students' difficulties. As a result, the element of information collection is observed through science inquiry and the element of information processing is observed in hypothesis setting step, inquiry result analysis step, and inquiry result sharing step. The element of information application is observed in the creation of posters for sharing and inquiry reports. Difficulties in information collection were found in lack of confidence in information gathering, systematic search strategy, and information reliability. Difficulties in information processing appeared in the inexperience of analysis program use, information transformation, and interpretation of linkage information. Difficulties in information application were caused by the lack of effective organization and effective expression of information. In this study, it is meaningful to provide a clue as to how the knowledge and information processing competence can be established in science education.

  • The active participation and active interaction of learners in small group science inquiry activities are the main factors that determine the effectiveness of science learning. Roles can be assigned to members of a small group to facilitate interaction between members within the small group. The purpose of this study is to analyze the effect of role assignment on the types and patterns of verbal interactions in middle school students' small group science inquiry activities. For this, 172 students from middle schools located in metropolitan cities were surveyed. We analyzed 18 small groups with assigned roles and 15 small groups without assigned roles. The change in verbal interaction type in small group science inquiry activity according to role assignment was largely divided into alienation and participation. In the case of small groups with assigned roles, the participation type occupied a higher proportion than the alienation type. The change in verbal interaction patterns did not show much significant differences when the role was assigned in terms of cognitive and affective. Based on this, further research is needed on how role assignment affects verbal interactions depending on the type of scientific inquiry and the stage of inquiry. In addition, further research on the composition of small groups and role assignment is required.

  • This study aims to develop performance criteria based on characteristics observed in science inquiry tasks for elementary school students. First, the performance characteristics by observing 70 fifth-grade elementary school students' science inquiry activity report are listed. Second, the checklist-type scoring criteria in connection with the theoretical framework of scientific inquiry process and relevant competencies are developed. Third, with the developed scoring criteria, 11 raters participate in scoring 350 students' reports. The main findings are as follow: first, the scoring data are well-fitted for the many-faceted Rasch model, and 22 scoring criteria are reasonably-well differentiated for various levels of proficiency. Second, at low performance level, observable characteristics are to answer questions explicitly required by the task or to observe objects or phenomena using pre-learned scientific concepts, while at high performance level, to explore additional data other than given data or to reflect on one's experimental process. Based on the results, the usefulness of analyzing students' performance characteristics for developing the scoring criteria, and further research directions are discussed.

  • The purpose of this study was to examine the consistency and balance of learning objectives of units and instructional units according to grades and educational domains. Educational domains were cognitive(scientific knowledge), scientific inquiry(inquiry process skills), affective(scientific attitude), and science-technology-society(STS). Learning objectives of life field of the 7th elementary science curricular teaching guidebooks were analysed. Scientific inquiry process skill objectives(43.5%) were most dominant in units, but cognitive objectives(53.9%) were most dominant in instructional units. STS objectives were most recessive in both units and instructional units. Especially, objectives of units and instructional units were shown no consistency by grade. The results of this study suggested that the textbooks and teaching guidebooks should be developed consistently by considering learning activities and contents on the basis of background and properties of science curriculum.

  • 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.

  • The purpose of this study is to investigate the effects of research project activities using the science writing heuristic on science inquiry abilities and attitudes toward science in high school students. For this purpose, we conducted the research project activities using the science writing heuristic consisting of questioning, experimental design, observation, argument and evidence, reading, and reflection steps for 73 students of the second year of science core course in high school in Jeonnam. In order to analyze the effects of the program, we surveyed the scientific inquiry ability and attitude toward science, investigated the perception of the research project class applying science writing heuristic, and conducted interviews when there was difficulty in interpreting the results. And the results of this study are as follows. First, among the science inquiry abilities, the score of Reasoning, Hypothesis setting, Finding variables, Operational definition, Experimental design, Graphing and data interpretation, Generalization was significantly improved statistically (p<.05), but the score of Expectation was not statistically significant (p>.05). Second, among the attitudes toward science, the score of 'Leisure interest in science', 'Enjoyment of science lessons', 'Career interest in science' was significantly improved statistically (p<.05). And the score of 'Attitude to scientific inquiry' decreased but it's not significant statistically. The high school research project applying science writing heuristic had a positive effect on scientific inquiry ability and scientific attitude but it could be burden to students because it is led by students in a form different from general science class for a long time. And so continuous study on research project that minimize these disadvantages and maximize their merits is needed.
