  • The purpose of this study is to draw implication for scientific inquiry study by investigating level of understanding and actual state regarding the elementary school teachers' scientific inquiry. The survey was conducted toward 42 elementary school teachers who work at the D city by using questionnaire of Views About Scientific Inquiry. Actual state of understanding of scientific inquiry was investigated by categorized the responses to the level of understanding of the eight aspects of scientific inquiry in three levels (informed, mixed, naive) based on analysis criteria. And analyze whether the characteristic of the subjects affect to level of understanding about aspect of scientific inquiry. As a result of the analysis, the two aspects among the eights aspects of scientific inquiry; 'Inquiry procedures are guided by the question asked' and 'Research conclusions must be consistent with the data collected' were appeared to have high rates of informed level of understanding. In the remaining six perspectives, most of elementary school teachers had naive and mixed level of understanding, so informed level of understanding took a relatively low proportion. It implies that elementary school teachers who teach inquiry in the field have limit to understand about scientific inquiry. These results indicated that experiences that have taught students and science related training courses that open sofar have a little influence to increase comprehension about scientific inquiry. Therefore, it is required to reinforce the teachers' understanding about scientific inquiry and to formulate different form of plan unlike existing way of teaching for teaching scientific inquiry.

  • This paper analyzed the improvement of cognitive level of the students and interactions which occurred in each step of free-topic scientific inquiry to help science teachers understand free-topic scientific inquiry better. Free-topic scientific inquiry is helpful to students with a deep strategic learning goal orientation type or a deep strategic ability goal orientation type in their transition (2B/3A) of cognitive levels. Most students have difficulties in the phase of establishing topics and hypotheses. The result says that the discussion techniques are improved through free-topic scientific inquiry, but the quality of interaction is not easily improved. The deep strategic learning goal orientation type concretizes opinion through interaction in free-topic scientific inquiry. The deep strategic ability goal orientation type are actively involve in the interaction, but they pay no attention to the process because they stick to the result. The surface strategic ability goal orientation type can not deepen a discussion due to high frequency of low level inquiry. However, the frequency of high level inquiry increases through free topic scientific inquiry operation. As a result, the characteristics of free-topic scientific inquiry were discussed and the educational implications of the progress of free-topic scientific inquiry and the organization of grouping were drawn.

  • The purpose of this study is to investigate the relationship between cognitive levels and achievement of science process skills. A science laboratory process skills test based on optional instrument of the SISS was administered to a sample of 162 students in the 8th grade. Practical assessment tasks consisted of the contents about acid, base, density, and a property of cobalt chloride. The format of this practical test was the station type that students had to conduct a short activity. Science process skills included three sub-skills which were categorized as designing, performing, and reasoning. As cognitive levels develop from concrete operational stage to transition stage and formal operational stage. total scores of science process skills and mean scores of sub-skills were significantly increased. Regardless of cognitive levels. all students were more successful on performing than designing or reasoning. In case of being controlled cognitive levels, gender differences and area differences were not detected in achievement of science process skills. According to these results. there was a strong relationship between cognitive levels and achievement of science process skills by practical assessment. This study implies that considering student's cognitive levels is very important for improving science process skills.

  • The purpose of this study was to investigate the effects of science inquiry experiments emphasizing social interaction on the development of process skills of the students. The social interactions by cognitive level of the students were also analyzed. For this study, 197 8th grade students were sampled. They were divided into an experimental group and a control group. During four-month period, the experimental group received science inquiry experiments treatment emphasizing social interactions while the control group received traditional treatment. Not only science inquiry ability pretest-posttest, but also multiple data collection method such as a questionnaire, class observation, and audio/video recording were used in collecting the data. According to the results of this study, it was found that the mean score of the experimental group was significantly higher than that of the control group at 0.05 level. It was also found that the students of high cognitive level led the peers and participated in the class discussion actively with the teacher while the students of low cognitive level followed the students of high cognitive level and showed inactive interaction with the teacher. Analysis of the students' perceptions on inquiry experiments showed that students participated in discussion actively in the class as these experiments gave an opportunity for them to discuss and were able to solve the problems with peers' help through discussion.

  • The purpose of the study is to investigate science process skills and suggest several considerations about developing scientific inquiries for secondary science gifted students. To do this, we analyzed scientific inquiries of science gifted programs and evaluated them on the quantity of problem perception, problem finding and inquiry planning that are regarded as high level science process skills, then revised each inquiry to include those high level skills. The result was that the first, there were differences in frequencies and types of science process skills among those inquiries. The second, there were very few problem perception and problem finding and were not many inquiry planning. The third, some of the revised inquiries showed those high level skills. From this, we would like to suggest we should construct scientific inquiries of science gifted program out of many and various themes. And there should be more high level science process skills such as problem perception, problem finding, and inquiry planning. For this, scientific inquiry developers should have intentions to involve such science process skills which is appropriate for science gifted student.

  • The purpose of this study is to develop cognitive scaffolding tools and to explore their effects on integrated science process skills of high school students. For this purpose, we developed cognitive scaffolding tools including one kind of classroom instruction for training integrated process skills and two kinds of individual learning materials that students can selectively study according to their level of inquiry ability. In addition, we developed hypothetico-deductive inquiry tasks as a tool to investigate the level of students on the integrated process skills for pre-test and post-test respectively. In order to verify the effectiveness of the cognitive scaffolding tools, we conducted inferential statistics on the pre-and post-tests of the experimental group and control group to examine statistical significance of students' inquiry level change depending on the usage of the cognitive scaffolding tools. We also produced Wrightmaps based on Rasch model to compare the change of inquiry ability depending on usage of the cognitive scaffolding tools. As a result, the experimental group using the cognitive scaffolding tools showed a significantly higher scores in all the components of integrated process skills namely, designing inquiry, collecting data, analyzing data, and forming conclusion than the control group. In addition, students who used cognitive scaffolding tools improved their inquiry ability and showed a distinct transition to higher level in each component of the integrated process skills. The results of this study suggest that high school students need cognitive scaffolding to alleviate or eliminate the functional barriers they face in conducting scientific inquiries.

  • Scientific literacy has long been as one of the key goals of science education, and using scientific inquiry in school science has became an important objective to be achieved. The processes of scientific inquiry consist of proposing/developing inquiry question, designing and conducting investigation, collecting, analyzing and interpreting data, and communicating the results. However, most students experience mainly collecting and transforming data in inquiry processes in science class and they are barely exposed to the opportunities of proposing/developing inquiry questions. Middle school earth science preservice teachers participated in this study (N=36) and their abilities of developing inquiry questions were surveyed. Participants' abilities of developing inquiry questions were investigated whether they were enhanced with activities using the Inquiry Questions Development Guide (IQDG). Also, this study was interested in whether there was any relationship between abilities of developing inquiry questions and designing inquiry investigation. The results of this study were as follows; first, the level and preciseness of inquiry questions and its preciseness developed by participating teachers were enhanced after experiencing IQDG. In addition, teachers' dominating inquiry question-types were two: one is a 'relationship-inquiry question' in which students could discover the relationship between results found in the given experimental situations and the other one is a 'why-how inquiry problem' in which students could explore a cause or a process that results in the outcomes. Finally, the higher level of and preciseness the of inquiry questions were identified as an important factor the determined teachers' abilities of designing more logical investigation. A process of proposing/developing inquiry question was identified as one of the most important processes contributing to a success of scientific inquiry investigation.
