  • This study intends to analyze open-ended inquiry activities of elementary science-gifted students in terms of how similar they are to authentic science inquiry and suggest desirable ways to make more effective programs for the gifted. For this study, we selected a small group with five elementary science-gifted students who had participated in the open inquiry program of summer camp held in the Institute for Science Gifted Education and collected data through recording and video-taping their discussion and performance from planning to coordinating inquiry results. The data was analyzed in terms of epistemological features and cognitive process in authentic science inquiry. The results is as follows. In terms of epistemology, students' inquiry methods were theory laden and they constructed knowledge in collaborative groups. For example, the students often discussed about performing the thought experiment and scientific concept related to inquiry task or their opinion. And in terms of cognitive process, their designing inquiry was similar to authentic science inquiry especially selecting variables, planning procedures, controlling variables, planning measures.

  • The purpose of this study is to consider the implications of science experiment in class and to seek a direction for its improvement. For this purpose, Science textbooks, teachers' cognitions, and classroom activities have been analyzed to find out how many and what kind of levels of inquiry elements are included in those. In this study, 22 teachers have participated in the questionnaire to investigate their perception about experiment class, and the two instruction cases in two classes of 9th grade have also been analyzed. Results show that most of the textbooks have included questioning, evidence collecting, explanation of phenomena, and connection with existing scientific knowledge. But the elements of communication and justification have been few. Most levels of the inquiry are teacher-led. Although the teachers thought communication and justification are important, their classroom activities does not coalesce with their thoughts. The students mostly spend their time with connecting evidence, they hardly explain the phenomenon based on the proofs as the results of experiment, and the activities of connection with the existing scientific knowledge, and communication and justification.

  • Inquiry-based experiments provide opportunities to understand scientific knowledge and acquire nature of science. In this study, the difficulties which pre-service teachers experienced in inquiry-based experiment class were investigated and analyzed. Twenty-two pre-service teachers attended course designed as ‘ill-structured inquiry’ for 13 weeks, and researchers investigated their difficulties by questionnaires and interview. They showed difficulties mostly in designing experiment and interpretation and also in understanding inquiry purpose, lack of prior knowledge, confidence in inquiry performance, and understanding of experimental instruments and facilities. As a result, it is necessary to provide opportunities to engage in inquiries and environments to properly instruct pre-service teachers the inquiry ability in college of education.

  • In this paper, an Online Scientific Inquiry Learning System was developed with the aim of improving student's scientific literacy and scientific inquiry ability. It was determined that there should be 4 distinct principles applicable to the design of the Learning system. First, it should enrich learner's motivation. Second, it should provide students with the chance for reflecting on the inquiry process. Third, it should emphasize multi-dimensional forms of interaction. Fourth, students should be able to create new information through it. The server system including the database, equation editor, reporting tool, search engine were all utilized for developing the learning system. In addition, the authors produced 24 web-based projects which were guided inquiry activities in which various inquiry abilities (reasoning, prediction, experiment design) could be developed. An Online Scientific Inquiry Learning System is not the only program which could be utilized in improving scientific inquiry abilities, but at the very least, such a system can serve as the prototype for developing an online learning system.

  • The purpose of this study is to investigate the understanding of nature of scientific knowledge and attitudes toward scientific inquiry of pre-service science teachers experienced open inquiry. The study was conducted in 10 sessions of open inquiry-based chemistry experiment. The subjects were 40 pre-service science teachers recruited from the experiment class. They received pre-test, mid-test, post-test on understanding nature of scientific knowledge and attitudes toward scientific inquiry of open inquiry activities. 20 pre-service science teachers among them participated in the interview. The results of this study are as follows. First, there was a significant difference in pre-service science teachers' understanding of the nature of the scientific knowledge (p<.05). In particular, understanding of creativity and sociality parts improved gradually. Second, pre-service science teachers' attitude toward scientific inquiry had changed negatively until the middle of the semester, and then changed positively later. The post-test score was significantly higher than the mid-test score (p<.05).

  • For teachers' conceptions and understandings are critical to their decision making and classroom practice, this study attempts to understand pre-service elementary teachers' views and practices of science inquiry during peer teaching practice. Fifteen 4th year university students in teacher education program participated in peer teaching practice. Their teaching and reflective discussion were video and audio recorded and written lesson plans were collected for data analysis. Five science teacher educators individually looked into the data and shared their comments and interpretations on pre-service teachers' views and practice. The study findings suggest that pre-service teachers emphasized the importance of providing students with motivating resources in the beginning of lesson, employing certain inquiry teaching models, the process of predicting and dis/proving via experiment, and teachers' minimal intervention as the important features of inquiry teaching. Science teacher educators emphasized that it is critical to help children understand inquiry questions in the beginning of inquiry process, to be mindful of children's problem solving and critical thinking rather than following instruction models or simply going through prediction and test process. They also commented that teachers' guidance could lead a good inquiry process in classroom practice, not always interfering students' inquiry. Based on the findings, the study suggests science teacher educators need to understand what and how pre-service teachers view and practice science inquiry teaching and consider these as useful resources where they can start effective teaching for pre-service teachers at the university level.

  • Inquiry activity contents presented at a chapter on natural environment and our lives in 6 science textbooks of the middle school were analyzed based on kinds of the inquiry Loaming classified by textbook. The number of inquiry activity subjects showed severe variation as mean value was 8.3${\times}$3.7 ranged from 4 to 15. Moreover, textbooks had little common point among each other as the percentage of subjects appeared together in the textbooks more than 3 kinds, 50% of total ones investigated, was just 26.3%. Data interpretation occupied significant position in the inquiry activity as 42% of total activity contents, whereas observation and experiment (or survey) did slight part of the activity as 10% and 16%, respectively even though they are main factors of science education. A model for field education based on the reasonable common subjects was prepared in the Gildong ecological park located In the eastern fringe of Seoul as a plan in order to solve the problems.

  • The purpose of this study is to design and apply a pilot inquiry experiment focusing on the epistemological issues of scientific activities, and derive educational implications by analyzing experimental activities and reflective discussions. Three graduate students who major in science education participated in the study voluntarily. Participants showed the characteristics of stable enquiry in Experiment 1. However, the small but continuous changes in Experiment 2 led the experiment to a phase of fluid enquiry seeking new theories. Participants mobilized various resources, proposed new hypotheses, and models and requested additional experiments to verify them. In the process of reflective discussions, the participants led to the following three epistemological issues. First, at the beginning of the experiment, their observations were theoretically dependent. Second, when the observations were no longer coherent with theory, they face a crisis, and the adjustment of observation and theory proceeds. Third, stable enquiry and fluid enquiry are performed according to the relationship between observation and theory. The educational implications of school science inquiry based on the above process and results are as follows: First, this study shows that fluid enquiry can follow stable enquiry naturally, and examples of the activities are presented together. Second, in this study, it was confirmed that participants could draw up epistemological issues based on their experiences through reflective discussions following inquiry.

  • The scope of this study is: (1) to review or summarize the theoretical explanations of diffusion; (2) to investigate the preservice teachers' understanding of diffusion utilizing the inquiry experiment of diffusion that was developed in this study. The data was collected through questionnaires given to 41 preservice teachers in 3 universities and interviews with 20 subjects from this population, who conducted the inquiry experiment. During the experiment, the data was collected from the students' reports and 3 small groups' audio/video recordings. To understand preservice teachers' conceptions, reports, audio/video recordings, questionnaires and interviews were analyzed and discussed with co-workers. The results follow: (1) The differences between effusion and diffusion as well as equal-pressure experiment and equal-flux one on diffusion were discussed; (2) Most preservice teachers understood effusion and diffusion connected to Graham's law of diffusion by rote and have misconceptions about the diffusion process; (3) They observed two kinds of diffusion experiments (equal-pressure and equal-flux) by inquiry experiment, but the majority of them failed to find conceptual differences between these experiments. After the inquiry experiment, about 40% of the samples modified their conceptions about diffusion.
