  • In this study, we investigated actual cases of assessment science teachers conducted and the cases they preferred in a typical situation based on the curriculum in the context of 'Scientific Inquiries in the History' of Scientific Inquiry Experiment. A questionnaire composed of descriptive questions was developed and a survey was conducted with 70 science teachers with experience in teaching 'Scientific Inquiries in History'. Interviews were conducted with eight of them. The assessment cases were analyzed in terms of the assessment areas and assessment methods, and the results were compared. The analyses of the results revealed that 'scientific inquiry ability' accounted for the highest ratio of the assessment areas in the actual cases of assessment. There were few cases that assessed the core concepts presented in the curriculum, 'the nature of science' and 'scientists' inquiry methods'. The assessment methods were greatly biased toward the report method and various assessment methods were not used. In preferred cases of assessment, the ratio of cases that assessed the core concept increased slightly, however the frequencies remained at a low. As for the assessment methods in preferred cases of assessment, the measurement methods decreased, the performance methods increased, and the informal methods which were not shown in the actual cases appeared. However various assessment methods were still not used. The causes of the survey results were analyzed based on the opinions of the teachers who participated in the interviews. Based on above results, plans to actively conduct NOS assessments in Scientific Inquiry Experiment are discussed.

  • In this study, pre-service elementary teachers (n=68) participated in an inquiry of exploring children's science ideas as group work. After conducting interviews with children, the pre-service teachers analyzed their science ideas on specific concept and propose a teaching plan based on their findings. This paper aimed to find the positive learning experiences of the pre-service teachers by looking into their inquiry process. Questionnaire, researcher's journal, classroom videos and final reports were collected and analyzed for this multiple case study. Four representative groups were chosen and interviewed after submitting their final reports for in-depth understanding of their inquiry process. The positive learning experiences found in the process of their inquiry into children's science ideas were as follows: (1) exploring children's ideas have brought the opportunity for enhancing pre-service teachers' science content knowledge. (2) the pre-service teachers developed their ability in creating questions that probe into children's understanding. (3) the pre-service teachers recognized that children have various incomplete and unstable science ideas. (4) the pre-service teachers could suggest teaching strategy based on their findings.

  • The purpose of this study is to investigate pre-service science teachers' difficulties in the 'inquiry mentoring' program, which was developed to improve pre-service science teachers' inquiry teaching ability. For this study, I developed the 'inquiry mentoring' program in which pre-service science teachers taught high school students. This program was adapted for 2.5 months, and 45 pre-service science teachers participated and taught 44 high school students. During this program, pre-service science teachers kept 'mentor diaries' and wrote 'mentoring reports' at the end of the program. Interviews were conducted with all pre-service science teachers. Results are as follows: first, pre-service science teachers thought that the difficulties in inquiry mentoring resulted from their inadequacy (mentor factor) than students' inadequacy (mentee factor). Second, pre-service science teachers perceived their lack of cognitive ability, inquiry ability and teaching ability as a mentor factor. Third, pre-service science teachers thought that they had difficulties in students' differences and lack of activity as a mentee factor. Fourth, they described difficulties caused by emotional distance as well as physical distance as an interaction factor. They also mentioned the difficulties related to teaching range and online interaction. Fifth, pre-service science teachers expressed a sense of frustration with the inquiry environment. Additionally, some implications were discussed for pre-service science teacher education through the 'inquiry mentoring' program.

  • This was a theoretical study of which the goal was to provide a foundation for developing and implementing earth science inquiry activities based on abduction as a scientific inquiry method. Through a review of relevant literature, the study examined the nature of earth science in terms of the goals of earth science inquiry and the characteristics of what is investigated in earth science. It also explored the forms and meanings of abduction, thinking strategies used in the abductive inference, and the abductive inquiry model. Abduction is the process of inferring certain rules (e.g., scientific facts, principles, laws) and providing explanatory statements or hypotheses in order to explain some phenomena. This method was found to be well-suited to the earth science inquiry which studies the causes and processes of natural phenomena in the earth and space environment. Abduction has the nature of ampliative, selective, evaluative, and creative inference, and several thinking strategies, including reconstruction of data, heuristic generalization, analogy, existential, conceptual combination, and elimination strategies, are employed for inferring rules and suggesting hypotheses. This study found the abductive inquiry model to be adaptable to earth science classrooms, and it is therefore suggested that earth science instructions should be based on the abductive method and that research work concerning the abductive inquiry in the classroom should follow.

  • The purpose of this study is to compare inquiry activities in science textbooks' physics contents for Korean secondary schools with those of Singapore in order to provide a reference for further improvement of inquiry activities in Korean science textbooks. We analyzed inquiry activities using the framework of Millar et al.(1998) and Chinn & Malhotra (2002). The results of this study are as follows: There are differences between Korean and Singaporean inquiry activities in the area of 'learning objectives', 'students' thinking activities' and 'degree of openness'. In the area of 'learning objectives', the Korean textbooks have more activities associated with the learning of science content than those in Singaporean, whereas the Singaporean textbooks have more activities associated with the processes of scientific inquiry than in Korean textbooks. In the area of 'students' thinking activities', the Singaporean textbooks have activities like 'test a prediction', which Korean textbooks lack. The 'degree of openness' is higher in Singaporean textbooks than in Korean textbooks. And some differences in the area of 'authentic scientific inquiry' between Korean and Singaporean textbooks were also found. While the Korean textbooks do not have any activities associated with 'generating research questions', the Singaporean ones feature such activities. In the area of 'designing studies', the Singaporean textbooks have activities corresponding to 'selecting variables' and 'controlling variables', while the Korean ones never have such activities. The results of this study imply that it is necessary to balance inquiry activities in the area of 'learning objectives', 'students' thinking activities' and 'degree of openness', and to present activities close to authentic scientific inquiry in inquiry activities in textbooks.

  • This study was to analyze science process skills related to 'state of matter' and 'state change of matter' in the kindergarten, elementary and middle school science textbooks. On the base of articulation, we analyzed science textbooks of the 5th kindergarten curriculum, the 6th elementary school science curriculum and the 6th middle school science curriculum. The findings indicated that the scientific inquiry abilities of predicting, classifying, hypothesizing and designing investigations are not enough in all grade science textbooks. Also, while young children have measuring ability theoretically, it was represented only in high grade textbooks. We concluded that these were inappropriate from the viewpoint of articulation which is related to scientific inquiry ability.

  • In this study, the characteristics of science inquiry problem solving were analyzed in the interactions between science process skills and science concepts by each related its category. Nine types of problem solving, which were based on two elements and the thinking aloud were found largely by protocol analysis, but six types when integrated similar thinking processes. There were quite differences in the representative types between students who succeeded and failed when science inquiry items were solved in the abilities of recognizing problems and generating hypotheses or those of drawing conclusions and evaluating. But there were not complete differences in those types between students who succeeded and failed when they were solved in the abilities of designing and performing experiments or those of interpreting and analyzing data. The data were divided into independent variables: $D_1,\;D_2,\;D_3,\;D_4,\;D$ and $C_1,\;C_2,\;C_3,\;C_4,\;C$ and dependant variables; $E_1,\;E_2,\;E_3,\;E_4,\;E$. The former consisted of the content-free science process skill achievement levels by each category of science inquiry skill and the science concept achievement levels, the latter the science inquiry problem achievement levels by each category of science inquiry skill. The regression equations were acquired within the 0.05 significant level by regression analysis: $E_1=0.03+0.16D_1+0.29C_1,\;E_2=-0.203+0.21D_2+0.45C_2,\;E_3=-0.32+0.13D_3+0.47C_3,\;E_4=0.61+0.09D_4+0.29C_4,\;E=-1.41+0.13D+0.47C$(E : the achievement of science problems, D : the achievement of science process skills, C : the achievement of science concepts).
