In this study, epistemological views of middle school students on scientific inquiry were investigated. The Views of Scientific Inquiry Questionnaire was administered to 141 9th graders. The questionnaire consists of five open-ended items concerning the contexts of scientific investigation, the methods of scientific investigation, the interpretation of data, and the data and evidence. Analyses of the results indicated that their epistemological understanding of scientific inquiry were not adequate on the whole. Although the students suggested a variety of factors influencing scientists' decisions on the questions and the methods of investigation, many of the factors were minor. Only a few students specifically described the activities of scientists and the constituents of "scientific" activity, and students did not demonstrate adequate understanding of experimentation in science and multiple scientific methods. Moreover, the percentage of students who possessed the informed view that data can be variously interpreted was found to be low. The students also did not understand the distinctions between data and evidence. Educational implications are discussed.

The purpose of this study is to examine the pre-service teachers' concept of measurement uncertainty. The subject of this study were 27 pre-service middle-school teachers in Seoul. They carried out open-ended inquiry tasks and surveyed two kinds of open questionnaires, and interviewed several persons. We analysed their behavior and responses. Through the analysis, we summarize pre-service teachers' concept about measurement uncertainty with representation data, precision and accuracy, error analysis, propagation of uncertainty. The results show that the teachers' concept is different from scientists' concept. They make a mistake in using term of precision and accuracy and pay no attention to measure precisely. Also they only point out sources of error but don't consider how the error affects the results of experiment. The results of study will give! 1 some implications for the curriculum and teaching material developers in order that pre-service teacher and student gain scientific concept.

The purpose of this study is to explore the relationship between epistemic goals, epistemic considerations and complexity of reasoning of science high school students in an open inquiry and to explore the context on how open inquiry compares with the characteristics of an authentic scientific inquiry. Two teams were selected as focus groups and a case study was conducted. The findings are as follows: First, the contexts, such as 'sharing the value for the phenomenon understanding, reflection on the value of the research, task characteristics that require collaboration and consensus, and sufficient communication opportunities,' promote epistemic goals and considerations. On the other hand, contexts such as 'lack of opportunity for critical review of related literature and environmental constraints' lowered epistemic sides. Second, epistemic goals and considerations influenced the reasoning complexity. The goal of 'scientific sense making' led to reasoning that pose testable hypotheses based on students' own questions. The high justification considerations led to purposely focusing attention to the control designs and developing creative experimental know-how. The high audience considerations led to defending their findings through argumentation and suggesting future research. On the other hand, the goal of 'doing the lesson' and the low justification considerations led to reasoning that did not interpret the meaning of the data and did not control the limit of experiment. The low audience considerations led to reasoning that did not actively defend their findings and not suggest future research. The results of this study suggest that guidance should provide communication and critical review opportunities.

In the application and composition of learning content, the field trip learning of scientific inquiry could provide a positive effect. Also, it can arouse an experience of various inquiry activities through open thinking. In addition, it could take a positive effect by providing the diversity and specificity of wildlife experience for the living organism. The biology inquiry program of the field trip is a necessary process to acquire ecological experiences in the learning context. However, there is some problem to solve before the performance of field trip learning as professional knowledge of the outdoors inquiry. Therefore, this study developed a field trip inquiry program for the plant in a coastal dune using artificial intelligence to assist professional knowledge. The researcher carried out literature reviews and analysis related to studies and programs to investigate learning steps, content, and strategy. Also, this study investigated the effects of the program on the affective domain of gifted elementary science students. According to the results of this study, the program can provide a positive effect on motivation, task commitment, and attitude level. Consequently, the field trip learning program for plant in the coastal dune using artificial intelligence developed in this study can arouse a positive effect on the affective domain. Therefore, additional study is necessary related to inquiry programs of the field trip for various students and sites.

A Science Camp Program was developed and applied as an intensified course for gifted students. The implications for the development and implementation of out-of-school science activities were also deduced through the analysis of the preliminary application results. The key point of the science camp program is to boost students' science inquiry skills through self-directed activities. Several positive effects in terms of interest and participation in the program were observed and some implications were derived as follows; (1) The program should provide the students with more opportunities for discussion and debate in group activities. (2) The tasks need be divided into two parts; basic tasks and optional tasks in order to ensure that the students engage in fewer tasks more intensively. (3) Each activity needs sufficient orientation taking consideration of the possibility that not all students may be ready for the inquiry. (4) The use of real examples of scientific research processes can help the students develop open inquiry skills and problem posing skills.

This study was designed to raise the quality of education programs for those gifted students in science education. The authors suggest the importance of autonomous inquiries amongst various activities for those gifted in this study. For this purpose, we identified the meaning of autonomous inquiry by comparison with the open inquiry and presented the importance of the autonomous inquiries with the aim of the gifted in science education. From this, we emphasized the necessity of program development to cultivate the gifted adolescents' independence, creativity, and autonomy beyond previous programs.

Recently, introduced open education, there are some models applied several cooperative teaming, but there is no case in applied Jigsaw Ⅱ. So this research is selected objects which are 147 students in the fifth grade in 1999' school year and 143 students in 2000's on Yongwon elementary school. It makes share a partial responsibility for planner, leader, investigator, helper, writer and reporter in the small groups, and apply the Jigsaw Ⅱ model. Qualitative and quantitative analyses show that they have effects of Jigsaw Ⅱ cooperative Learning on Student's knowledge, inquiry ability and attitudes on Elementary School Science Study. The final results are following. The significance of Knowledge has .02 in 1999 and .01 in 2000. Testification of Inquiry ability has 1.75 in 1999 and 2.25 in 2000. The significance of Attitudes has .03 in 1999 and .00 in 2000. Research that has emerged from the cooperative teaming has led us to better understandings of multi purposed roles, interactions, and communities that arise when students work together to team science. Each of students can also cooperative as co-builders, working as equal participants to create a product that is better than that while would have built by either individual alone. Upon asking their intention, cooperative loaming shows more participation.

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.

The 'Integrated Inquiry' unit is a new addition in the 5th~6th grade science textbooks, and was developed for the 2009 revised national curriculum. The unit deals with six integrated inquiry process skills: problem cognition, formulating hypotheses, controlling variables, transforming and interpreting data, drawing results, and generalization. The purpose of this study is to investigate the perceptions and the teaching practices of elementary school teachers on this unit in their school curriculum and where improvements can be made. Data was collected from questionnaires filled out by 92 elementary school teachers. The results are as follows: First, teachers do have a positive perception on the importance of teaching integrated process skills. Second, with that being true, this unit ended up receiving both positive and negative reviews by teachers. This research found that there were good and bad responses on the educational aspects of this unit in three particular areas: dealing with the development of integrated inquiry process skills, facilitating science learning in other units, and implementing open inquiry. Third, teachers have difficulties particularly in problem cognition, formulating hypotheses, controlling variables, transforming and interpreting data, generalization, and drawing results. There is a lack of student understanding as well as a lack of professionalism for teachers on this unit, and many issues related to the composition of the textbook. This study may have important implications for making improvements in this unit and teaching integrated process skills.
