  • 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.

  • 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.

  • This study investigated the effects of scientific inquiry experiments emphasizing social interaction on the academic achievement, the ability for science inquiry and the learning motivation of the students. To examine the differences among the classes of scientific inquiry experiments according to the way of organizing small groups, the effects of the group in homogeneous cognitive level and the group in heterogeneous cognitive level were compared. 255 7th-graders were grouped into the treatment group and the control group. After the treatment group received the scientific inquiry experimental lessons emphasizing social interaction and the control group received traditional lessons for one year, academic achievement, ability for scientific inquiry, and learning motivation were examined. These inquiry experiments were composed of four steps which are eliciting, familiarizing, constructing and bridging. And students can interact with peers and teachers through the process of relating observed phenomena to concept, constructing experiment procedure, and eliciting results. The ANCOVA results revealed that there were significant effects of science inquiry experiments emphasizing social interaction on the academic achievement, the ability for scientific inquiry and the learning motivation of the students. The significant academic achievement of the students in most of the cognitive levels, if not all, was found and degree of improvement in the ability for scientific inquiry was lower than that in the academic achievement. Concerning the effects according to the way of organizing small groups, there were significant improvement in academic achievement and learning motivation of the group in homogeneous cognitive level compared to the group in heterogeneous cognitive level. These results indicate that social interaction in learning is important and it has positive influences on the improvement in academic achievement and ability for scientific inquiry of students.

  • The purpose of this study was to investigate the effects of reflective thinking-based laboratory report on learners' metacognition and inquiry skills. In a general physics experiment class consisting of 11 experiments, 20 college students used reflective thinking-based laboratory report, and then the changes of their metacognition and inquiry skills were compared with those of who used general laboratory report. The opinions of students used reflective thinking-based laboratory report were surveyed. The results showed that their metacognitions were increased more than those of comparison group that used common experiment report. Their inquiry skills also were increased as much as comparison group's. According to the survey results, they recognized that reflective thinking-based laboratory report helps to improve their performance, metacognitions, and inquiry skills.

  • The purpose of this study was to evaluate the level of elementary gifted students' argumentation and examine the special features of argumentation founded in scientific inquiry. 28 students were selected in the special education center for the gifted in K National University. They were organized 8 groups of 3~4 students and engaged in scientific inquiry activity. The researcher wasn't involved in students' inquiry activity and argumentation except for the guiding and introducing their activity. In the first session, each group carried out the experiment 'Putting a heated can in the water' and then, the students discussed to probe their experimental results and build their explanation. In the second session, each group presented their experiment results and evidence from their experiment justifying their claims, and had questions from other groups. The protocol data during 8 groups' argumentations were analyzed using 'Rubric for Scientific Argumentation Assessment' (Yang et al., 2009) in three domains- the form, content and attitude. As a result, in form domain, almost groups were rated 2 points due to their argument without rebuttal on the subcategory of 'composition', but they got a good grade above 3 points in subcategory such as 'claim', 'ground', and 'conclusion'. In content domain, almost groups got points above 3 points. In attitude domain, there were some striking contrast between each groups. Six groups got good score more than 4 points on the subcategory of openness, but two groups, they alleged and got score below 3 point. While the 6 groups of all got 4 points in the aspect of participation, 3 groups got 3 points lower than because they only just asserted and not interact with other groups. Throughout the argumentation, two features were found that; as time goes by, arguments were refined; Students tended to use their prior to knowledge rather than evidence such as experimental data in making claims and conclusions.

  • In this study, elementary school students' science learning characteristics together with the levels of inquiry requirement in elementary school science experiment instruction were investigated in terms of the affective domain. We divided seventy-three students of the fifth ade into two groups according to the levels of inquiry requirement. After each instruction had been implemented, the characteristics of the students' learning in terms of the affective domain were compared and analyzed within the context of the levels of inquiry requirement. There were no significant differences between Level 1(LL) and Level 2(HL) groups in terms of the affective characteristics. These results may be caused by the burden imposed by the difficulty in thinking through and setting up the experimental methods. However, the HL group students' levels of interest in science experiments was higher than that of the LL group. In conclusion, the HL instruction contributed little to the improvement of affective characteristics. Some possible reasons might be that students felt difficulties with the somewhat unfamiliar instructions which required them to design and perform experiments. Higher levels of interest in science experiments amongst HL students' implies that well-organized and continuous exercises involving the design and performance of experiments could improve students' scientific affective characteristics.

  • Argumentative discussion is one of the important components of an educational program, which allows students not only to learn the process of social negotiation through discussions, but also to improve students' overall research abilities. The purpose of this study was to examine a) the changes between inquiry of before-argumentative discussion and inquiry of after-argumentative discussion, and b) the connections between the inquiry changes and online argumentative discussion. This study analysed 726 messages in an online argumentative discussion, as well as in first research reports and second research reports. The results of the study indicate that science-gifted students' research abilities were improved through on-line argumentative discussion that provided them with feedback based on interactive discussions, and encouraged them to re-examine hypotheses and experiment processes. The science-gifted students showed knowledge and abilities for identifying simple errors in research processes and arguing problems in the flow of the whole logic of research.

  • 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.
