  • This study was performed to find the environmental factors of inquiry instruction perceived by secondary school science teacher. The instrument consisted of three domains such as teaching conditions, viewpoints of secondary school science teachers of environmental factors for inquiry instruction, and barrier and improve! rent factors of inquiry instruction. Teaching conditions between middle school and high school science teachers were not different significantly. Environmental factors of inquiry instruction of secondary school science teacher included five factors such as 'facilities and encouragement', 'amount of works and materials', 'teacher education and textbook', 'practice and knowledge' and 'perception of necessity and satisfaction'. And all factors except 'perception of necessity and satisfaction' were very low state for inquiry instruction. In the disturbant and improving factors, the critical factors were 'over students per class', 'textbook' and 'learning materials' for middle school science teachers, and 'over students per class', and 'entrance examination' for high school science teachers. Thus the development and diffusion of adequate inquiry learning materials may be helpful to practicing inquiry instruction as decrease of works and psychological charges, and it is needed to reorganize systematically and intensify pre- and in-service teacher education to practice inquiry instruction.

  • This study aims to find out the effect of pre-service elementary teachers' experiences of inquiry performance in the life on their images about a scientist and science teaching anxiety. Thus, this study selected 162 college juniors who completed 'Science Teaching Material Research & Teaching Methods' for one semester at a university of education. Groups of 3 to 4 pre-service teachers were made to select one of the 10 experimental topics and inquired it for themselves, and make a presentation about the results before the other pre-service teachers. The results of this study can be summarized as below. Firstly, as a result of investigating pre-service elementary teachers' opinions about the characteristics of scientists, it was found that they thought of scientists prudent, intellectually superior, creative, and hard-working, but did not consider them artistic or religious, no matter if they had inquiry performance experiences. Especially, to such characteristics as intellectually-superior, creative, open-minded, outgoing and responsible, they showed more positive responses after inquiry performances. Besides, in scientists' activity types shown in pre-service elementary teachers' drawing pictures of a scientist, 'Experimental Activity' increased most after their inquiry performances, and in the place of activity, 'Laboratory' was most since it was related to activity types. Secondly, as a result of examining per-service elementary teachers' science teaching anxiety before and after inquiry performances, it was found that they showed statistically significant differences in all the domains, scientific knowledge, inquiry class preparation and inquiry class management. This finding could be interpreted as their inquiry experiences had positive effect on their having confidence in teaching science.

  • 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.

  • This study has developed the earth science class model based on flipped learning and analyzed the effects of that model at the elementary pre-teachers' science classes. The model of this study, the material which was consists of all contents and information about classes was offered to learners before science class as a substitute for preceding homework at general flipped learning. In science class, the knowledges which were recorded in materials were explained directly to learners by instructor for 20minutes. So the learners resolved some inquiry questions in materials through mutual debate collaboration with learners in small group. After inquiry questions' resolving, the learner among small group makes a presentation in front of the whole class. At the same time, the instructor evaluated learning action of all small groups' learners during the classes as process evaluation. The final evaluation results of semester were obtained scores of the small group in 14 classes and the achievements of individual portfolio as final exam. The learners were very positive perception to this science class model, why it is helped to concentrate on the class, extended debating and thinking ability. Consequently, the class model of this study is useful to applicate the earth science classes.

  • The purpose of this study was to understand science teaching experiences of elementary school teachers who taught the system thinking-based science inquiry class. The phenomenological methods were applied to analyze four elementary teachers' meaningful experiences. The four step methods of phenomenological experience research proposed by Giorgi (1985) and interview questions developed by Seidman (1998) and Schuman (1982) were used in order to collect qualitative data. The major findings of this study were as follows: First, teachers intentionally tried to ask divergent thinking questions which promoted the system thinking in classes. The teachers used divergent thinking questions to promote their students' thinking activities and to induce students' system thinking. In addition, the receptive mood created by teachers and interactive environments had a positive effect on promoting system thinking skills. Second, teachers remarked lack of teaching and learning materials and difficulties in selecting themes of their classes in order to teach the system thinking-based science inquiry class effectively. In addition, it was very difficult for teachers to evaluate the contents and processes of students' learning correctly because there were little evaluative tools and methods readily available. The findings indicated that there were some limitations in maximizing the effects of system thinking-based science inquiry instruction due to elementary students' inappropriate process skills of inquiry activities. Findings of this study revealed significant insights about elementary school teachers' experiences regarding the system thinking-based science class.
