  • The purpose of this study is to compare by learner groups(K-12, geology-related majoring students, science teachers) how geologic fieldwork education cases in domestic and foreign papers for recent 20 years reflect the elements of inquiry in field geology. The total number of analyzed cases is 53(58 for double counting), and the analysis was conducted on the elements of inquiry in field geology and their sub-element. As a result, there was a clear difference between the cases of geologic fieldwork education for K-12 and college students majoring in geology-related disciplines, in the way of reflecting elements of inquiry in field geology. Because most of K-12 target fieldworks were designed based on the curriculum, it mainly included 2-3 elements of observations, representations, and/or abductive reasoning. On the other hand, because fieldworks for geology-related major students aim to train geologic experts, it diversely contained four or five of the elements of inquiry in field geology, including spatial thinking and diachronic thinking in a high proportion, and also frequently used activities that require specialized skills such as geological mapping. Fieldworks for science teachers were found to have mixed features of K-12 and geology-related major students. Considering the diversity of included inquiry elements, similarities with the activities performed by geologists, and the autonomy of learners, it was analyzed that geologic fieldwork for geology-related major students was more close to authentic geologic inquiry than fieldwork for others. Based on the results of this study, we suggested implications for improving geological fieldwork as authentic science inquiry.

  • The purpose of this study was to investigate elementary teachers' views on the barriers in implementing inquiry-based instruction in science education. For this, semi-structured in-depth interviews were performed with 22 elementary school teachers who have served for more than five years in the Gyeonggi province. The interview questions were developed through triangulation of Seidman's phase to achieve reliability in the interview data, then interview questions were modified and completed through an analytic induction method in pre-interviews. In-depth interviews were performed individually and all the interviews were recorded. The data of teachers' views on the barriers were categorized and analyzed into external and internal factors of teachers. The study found that the external factors referred by teachers included the following; the lack of a unit time, lack of materials and equipments, too many students in a class, problems in science curriculum management, difficulty in the assessment of students' inquiry activities, the students' learning, lack of opportunities for teaching inquiry activities, harmfulness of accidents, and so on. Internal factors included the following; lack of preparation for inquiry activities, lack of self-confidence, lack of patience, and so on. The various barriers presented and their causes were analyzed in detail, and possible efforts in activating inquiry activities in elementary science education were suggested.

  • Scientific inquiry has emphasized its importance in various aspects of science learning and has been performed according to various methods and purposes. Among the various aspects of science learning, it is emphasized to develop core competencies with science, such as scientific thinking. Therefore, it is necessary to support students to be able to formulate scientific reasoning properly. This study attempts to explore problem-finding and scientific reasoning in the process of performing scientific inquiry. This study also aims to reveal what factors influence this complex process. For this purpose, this study analyzed the inquiry process and results performed by two groups of college students who conducted the inquiry related to osmosis. To analyze, research plans, presentations, and group interviews were used. As a result, it was found that participants used various scientific reasoning, such as deductive, inductive, and abductive reasoning, in the process of problem finding for their inquiry about osmosis. In the process of inquiry and reasoning complexly, anomalous data, which appear regularly, and the characteristics of experimental instruments influenced their reasoning. Various reasons were produced for the purpose of constructing the best explanation about the phenomena observed by participants themselves. Finally, based on the results of this study, several implications for the development context of programs using scientific inquiry are discussed.

  • The purpose of this study is to estimate the ability of inquiry performance for students gifted in science in elementary school. 56 sixth graders were included in this study. Initially, a question 'How does the dust effect on human health?' was posed to students. Then, an assessment framework for analysis of the inquiry report was developed. It is composed of 5 domains: data collection, prediction, the inquiry process, results, conclusion and presentation. The findings reveal that the students achieved high scores in the domain of 'data collection' and followed by prediction, inquiry process, results, conclusion and presentation. The results of our study are as follows : first, in spite of high scores obtained in basic inquiries such as data collection, students needed to improve their skills in prediction, the inquiry process, results, conclusion and presentation. Second, the reason why students were outstanding in data collection is that they have improved their ability to handle data in a know-ledge-based information society. Third, even though students were good at citing and applying some information, they didn't fully understand the meaning of data and exhibited weaknesses in arguing their own opinions.

  • The purpose of this study is to develope and analyze a test for the assessment of physics inquiry experiment. To do this, three experiments about 'analysis of motion', 'the relation of force and acceleration', and 'free fall motion' in high school physics textbooks were chosen, and 5 scientific inquiry domains and 16 science process skills have been specified. For each experiments, test sheet of $29{\sim}44$ questions for assessing students' ability about physics inquiry experiment were developed on the basis of the scientific inquiry processes developed earlier. After instruction about 3 experiments mentioned above, a test was administered to the students who took experiment. After the adminstration of a test, the ratio of correct answers, discrimination index, and reliability were analyzed. Using the ratio of correct answers, we can determine item difficulty. Through the D.I(discrimination index), we can find which items can discriminate the students who took experiment well from those who took experiment badly, and we can also find the stability of a test result by the reliability analysis. The test developed in this study were also administered to the students who did not take experiments, and the results were compared with the those of the students who took experiments. With the comparison by chi-square method, we could find which items can discriminate the students who took experiments from those who did not take experiments.

  • The study presents preliminary research on how science activities focusing on problem recognition worked and affected students' perception of their learning environment in a sixth science classroom. The science activities were based on the Science Writing Heuristic (SWH) which was suggested by Keys, Hand, Prain & Collins (1999), where problem recognition was an important part of scientific inquiry. For developing the working sheets for the modified SWH in this study, analyses of target units of 6th grade science curriculum in the aspects of problem recognition were conducted. After consecutive 6 classes with the developed working sheets for sixth graders, the student working sheets for each lesson were collected and analyzed. In order to investigate the developed units' affect on student learning, students' perceptions of their learning environment were administered before and after the applied classes. Students working sheets and questionnaires on their perceptions of learning environment indicated that students perceived that the science activities were more student-centered classes where students had active discussion and dialogue with one another giving them more chances to actively take part in the class as well as they used more properly recognized their inquiry problem.

  • The purpose of this study is to help science gifted students construct posters after conducting scientific open inquiry. To this end, we analyzed 25 posters written by elementary science gifted students and extracted deficient aspects from the posters. Based on this, a checklist consisting of 17 items in 5 categories was developed to help students construct posters. By applying the developed checklist to the evaluation of 14 posters constructed by science gifted students in middle school, the correlations between evaluators and Cohen's kappa values showed high reliability. In addition, by comparing the evaluation results of the seven 7 posters constructed using the checklist with the evaluation results of control group, a significant difference at the level of p<.01 was obtained, therefore, the usefulness of the checklist was confirmed. Students who used checklists responded positively, including that the checklist helped them to recognize deficiencies in their inquiry and to construct posters systematically without omitting key items of the posters. Finally, additional considerations were discussed for the preparation and presentation of the students' posters.

  • This study is aimed at exploring the effects on Science Inquiry Ability, Scientific Attitude and Science Achievement of the Elementary School Students according to the Input time of Web-Based Instruction Programs. As the object of the study, seventy-two students were selected from three classes in the fifth grade of Y Elementary School located in the city of T, Gyungsangnam-do. They were classified into the three groups such as Group A (Class 1), Group B (Class 2) and Group C (Class 3). The author threw web-based instruction programs into the begining of a unit, during a unit, the end of a unit to each group, and explored the effects. The results of this study were as follows: First, for the learning effect of science inquiry ability, it was indicated that there was the highest effect in the case of throwing web-based instruction programs into during a unit, but the effect reduced a little in the case of throwing them into the end of a unit. Secondly, the scientific attitudes tended to be reduced in the case of throwing them into during a unit, but there did not occur statistically significant improvement. Thirdly, the degree of improvement of the science achievement tended to be highest in the case of throwing them into the end of a unit. Such findings indicated that the time of throwing in web-based instruction programs affected science inquiry ability, scientific attitude and science achievement of elementary school students. Thus, it will be said that teachers need to teach their students with the class strategies of considering various scientific elements revealed at the time of throwing in web-based instruction programs.

  • The purpose of this study was to investigate how prospective elementary school teachers perceived teacher's inquiryoriented teaching practice, with an emphasis on students' scientific explanations based on scientific evidence. For this study, 94 prospective elementary school teachers were participated. 14 among 94 participants had chances to intensively experience this particular teaching methods for 15 weeks. All of the 94 participants observed the intended science teaching practice for 4th graders in two different elementary schools, which utilized the science talks emphasizing students' scientific explanation activity. For quantitative data analysis, they were asked to provide their reaction to the science teaching methods after their classroom observation. For qualitative data analysis, 5 among the participants, who had relatively long term experience with this teaching practice, were chosen to interview in order to understand their individual reasons of the ways they perceived about the inquiry-oriented teaching methods boosting students' scientific explanation. The results show that the prospective elementary teachers generally thought the emphasis of students' scientific explanation based on scientific evidence could enhance young elementary students' science content understanding, stimulate their curiosity/interests, and further develop their ability to engage actively in scientific discussions. However, some prospective teachers tended to think that the science teaching. methods would not be effective in terms of managing science classes, though. This study concludes that the prospective teachers tended to hold an endemic dilemma. On the one hand, they had their clear preference to the inquiry-oriented teaching practice as the most ideal teaching methods. On the other hand, they also had their persistent hesitance in using these methods due to their fear that elementary students might not adequately grasp the important science content when engaged in scientific discourse through an inquiry-oriented class.
