  • In National Curriculum of Science revised in 2007, 'Free Inquiry' was newly introduced to increase student's interest in science and to foster creativity by having students make their own questions and find answers by themselves. The purpose of the study was to analyze characteristics deployed in the processes of elementary school students' free inquiry activities applying a brain-based evolutionary science teaching and learning principles. For this study, 106 the fifth grade students participated, and they performed individually free inquiry activities according to a brain-based evolutionary approach. In order to characterize the diversifying, estimating-evaluating-executing, and extending-applying activities in behavioral domain, the free inquiry diary constructed by the students, observations by the researcher, and interviews with the students were analyzed both quantitatively and qualitatively. The major results of this study were as follows: First, the students preferred basic inquiry process skills and the majority of the students selected observation as a major approach of their inquiry. The reason was found to be that they were accustomed to only typical basic inquiry skills which is frequently presented at textbooks and regular instruction and didn't have appropriate experience for using relevant integrative inquiry skills. Second, most of the methods diversified and selected by the students were confined to descriptive explanation rather than causal one. Third, both of the science attitude and academic achievement were associated with the number of diversified methods and the selection of appropriate method. Based on these findings, implications for supporting domain novices in inquiry learning environments are advanced.

  • This study is intended to develop plant inquiry instruction using Rapid-cycling Brassica rapa (RcBr) whose life cycle is relatively short, and to apply it to the elementary science instruction of the 4th grader and examine their plant concept, science inquiry skills and science-related attitudes. The materials were consisted of laboratory manuals for the students as well as teachers' guide. By observing the life cycle of RcBr, students can experience the conceptual learning of the plant's life cycle. In addition, this study investigated the cause of change in science inquiry skills and science-related attitudes by interviewing 12 students. It has shown that plant inquiry instruction using RcBr has meaningful effects on students' understanding of the plant concept, improving students' science inquiry skills, and changing students' science-related attitudes. Students who showed improvement in science inquiry skills were able to answer questions regarding science knowledge correctly. And students whose science related attitudes were improved had a positive attitude on cultivating RcBr. Students told that RcBr was an interesting and good material to inquire plant. Because of its small size and its relatively short life cycle of RcBR, it should be a desirable plant material for the inquiry instruction which can give rise to useful and meaningful results for the elementary school students.

  • Inquiry occupies an important place in science education, and research related to inquiry is widely conducted. However, due to the inclusiveness of the concept of "exploration," each researcher perceives its meaning differently, and approaches may vary. In addition, criticisms have been raised that the results of classes using inquiry in science education do not guarantee meaningful changes to students. Therefore, this study attempts to identify the trend of SSCI-level research papers dealing with inquiry in science education over the past three years to confirm the current status and effectiveness of the inquiry. Researches used in the analysis are International Journal of Science Education, Journal of Research in Science Teaching, Research in Science Education, and Science Education, and limited to those that directly suggest "inquiry (enquiry)" as a keyword. Based on extracted 75 papers, the classification process was conducted, and an analysis frame was derived inductively by reflecting the subject and characteristics. Specific cases for each category were presented by dividing into three aspects: perception and perspective on inquiry, support and strategy for inquiry, and teacher professional development for inquiry. The results of examining the implications for scientific inquiry are as follows: First, rather than defining inquiry as an implicit proposition or presenting it as a step-by-step procedure, it was induced to grasp the meaning of inquiry more comprehensively and holistically. Second, as to whether the inquiry-based instruction is effective in all aspects of the cognitive, functional, and affective domains of science, the limitations are clearly presented, and the context-dependent and subject-specific properties and limitations of inquiry are emphasized. Third, uncertainty in science inquiry-based instruction can help learners to begin their inquiry and develop interest, but in the process of recognizing data and restructuring knowledge, explicit and specific guidance and scaffolding should be provided at an appropriate timing.

  • The purpose of this study was to develop a spider inquiry program for elementary school students based on the scientific-knowledge generating model. For the purposes of this study, we selected three species of snider (e.g. Pardosa astrigera, Argiope bruennichii, Nephila clavata) which were easily found in a school garden by elementary school students. The spider inquiry program was based on a model of the process of scientific-knowledge generation, and consisted of two sections: for students and teachers. The students' program was designed to generate scientific-knowledge, whilst the teachers' program was designed to guide the inquiry smoothly even in the case of teachers who lack experience in inquiry activities or possess limited subject knowledge on spiders. As a result, this program was found to have an influence on generating the scientific-knowledge of elementary students and the results further suggest that it may be helpful to teachers conducting an inquiry activity. Additionally, this program could be used as a selective activity lesson such as a science inquiry lesson, or as a biology inquiry class, as a weekend life experience study or as an activity on a science camp.

  • In this study, we investigated the characteristics of the authentic inquiry components in the inquiry tasks of Science Inquiry Experiments textbooks developed under the 2015 Revised National Curriculum. After classifying inquiry tasks by core concepts, we analyzed the cases that students autonomously planned or performed the authentic inquiry components. The results of the study revealed that investigating multiple materials component most frequently appeared in all units. However, generating research question, selecting variables, observing multiple variables and transforming observations components appeared in a few tasks of history and everyday science units as they were often guided or structured in textbooks. Controlling simple or complex variables, observing intervening variables and considering methodological flaws components rarely appeared in all units as most of textbooks did not consider or indicate explicitly. Authentic inquiry components of everyday science unit tended to be handled in small group activities. On the bases of the results, the implications for the development of the inquiry tasks of Science Inquiry Experiments textbooks are discussed.
