  • The self-directed inquiry to improve students' core scientific competency is an important teaching method. Students experience a variety of difficulties in carrying out their inquiry tasks, sometimes fail to produce the desired results, or fail to perform a meaningless inquiry. This study was conducted to identify the causes of difficulties and failures in students' self-directed scientific inquiry. The study involved 16 high school students with experience in science research at science high schools and science-focused high schools. The data collection consisted of in-depth interviews centered on semi-structured open questions. Qualitative data analysis was imputed by finding paragraphs from the interview material that might reveal the difficulties and failures experienced by participants and the reasons for them. The study found that most of the causes of failure were lack of ability, incomplete procedures, and selection of complicated tasks. A variety of cognitive biases, such as overconfidence, planning fallacy, and groupthink, were also analyzed as causes. Based on the results of the study, it is necessary to develop an educational strategy that students can be fully prepared to reduce their trials and errors in a self-directed inquiry maximally.

  • In this study the authors developed the practice-centered science camp program which was based on the review of out-of-school scientific activities and the standards of HASA (Hands, Head and Heart At Science Activity) curriculum emphasizing on hands-operated skills. After applying this science camp program we confirmed the validity of the program based on the students' responses at the camp. Using students' reports written during the camp and their essays written on the web-site after camp, we analyzed students' responses into four categories; knowledge, inquiry, hands-operated skills, and scientific attitudes. Also we evaluated the components of the science camp programs and students' perception of science and science-related attitudes using a questionnaire before and after the camp. In terms of contents and activities for the development and application of science camp, our result showed that the science camp program should be complemented to connect real life with high-tech science and include more activities related hands-operated skills and competition activities evoking constructive competitive spirits. In conclusion, we can infer that the agencies which take parts of the national policy enterprise related science education, such as Scientific Education Research Center, must develop and specialize science camp program with more competitive human resource system and economic support. Science educators should give more attention on joining school science education with out-of-school science education, which might have a positive effect on students' attitudes and participation toward science.

  • Inquiry became an essential methodology in science education. Recently, argumentation becomes more important in inquiry, but inquiry-based teaching in school science would not provide enough opportunities for students to have voluntary and active interactions during inquiry activities. Informal science learning can be an alternative for authentic inquiry. Accordingly, this study aims to find interaction patterns in dialogic inquiry of junior high school students in small groups in the natural history gallery. Inquiry elements and interaction patterns are analyzed with 42 dialogues of 13 small groups. As a result, seven interaction patterns are identified. First, five major interaction patterns were drawn as follows; Sharing questions, asking questions and simple response, asking questions and simple explanation, asking questions-simple explanation-(collecting data)-data based explanation, and asking questions-collecting data-data based explanation. Second, pattern 2, 'asking questions and simple response', is subdivided into three categories; passive and/or evasive response, inaccurate response, and repeated patterns of asking questions-simple response. The results of the study provide different patterns of dialogic interactions in a small group inquiry in informal contexts from formal contexts, and provide foundations to understand middle school students' interactive dialogues of inquiry occurred in the natural history gallery.

  • In this study, a restriction enzyme mapping inquiry experiment was developed for cultivating basic knowledge on molecular biology and the effects on inquiry experiment ability and positive experience on science through student-centered molecular biology inquiry experiment class for second graders of a general high school was analyzed. First of all, it was found that the experimental class through the inquiry experiment was significantly effective as the percentage of high school students who answered 'yes' or higher in the positive science experience of general high school students was higher after than before the test. As a result of developing and applying a series of five classes for the creation of restriction enzyme maps, not only did the students' interest in science studies, but also their class participation increased. They were also used as effective specific science learning motives, science career aspirations and experience data. The science environment of the inquiry experiment class led to the improvement of students' learning attitudes and positive science experience, which had a positive effect on the importance of class concentration and class quality, active communication and mutual cooperation among students. In addition, inquiry and experiment classes will provide opportunities for career experience, which will become the foundation for cultivating basic knowledge on molecular biology and advancing to science and engineering.

  • 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.

  • This study is to design, develope, and deploy of e-learning inquiry based content in elementary science class. First, this study analyzed related literature review, case studies, and inquiry based class models for seeking better applicable design and development modes. From focus group meeting, experts discussed the inquiry content design ideas for elementary students for science class. This study finally established its own inquiry design mode for online science class with the flow of understanding of problem, sep up hypothesis, problem solving, and solution analysis. The developed content was deployed in real classroom setting to see how students received the contents and how well they processed the learning activities. We found that inquiry based online content, especially when applied to science subject, can be effective in students interests and their motivations. We also observed that there were a few managerial errors such as detailed lesson guidance and tutor support for students activities. This study concluded that inquiry based online contents should be designed considering students interests based on learning subjects and also developed in terms of students interests and strong motivation as well. We suggest that related research should be expanded toward to other subject than science and various students age groups.
