In this study, open inquiry reports of 165 eighth graders in Daegu were analyzed in terms of content area, the types of inquiry hypothesis, and the types of inquiry variables. Before summer vacation, students learned about inquiry process and explored their own inquiry topic for two class hours. During summer vacation, students performed open inquiry including problem selection, designing and performing experiment, data collection, data analysis, and writing report. After the vacation, students submitted their reports, and answered to additional survey regarding the source of inquiry idea, the definition of hypothesis, and the most difficult step of inquiry process. As a result, chemistry was the most dominant content area of the reports and biology and life science were the next. 130 out of 165 reports included inquiry hypotheses, and most of them were predictive hypotheses. In many reports, dependent and independent variables could not be identified because of their ambiguity. However, inquiry variables described in experimental design, which were mostly categorical variables, were clearer than those described in inquiry subject and inquiry hypothesis. The most difficult step of inquiry process for students was to generate an idea for open inquiry.

The purpose of this study was to explore the relationship among science process skills. mental capacity and cognitive styles of elementary students. For the study 264 fifth-grade students were sampled. The Test of Science Process Skills(TSPS) was used as a measure of science process skills. Figural Intersection Test(FIT) was used as a measure of mental capacity. Group Embedded Figure Test(GEFT) was also used as a measure of cognitive styles. The results of this study showed that the science processskills increases progressively as the mental capacity increases. The field independent students showed significantly higher(p<.05) science process skills than the field dependent ones. There was no significant interaction between mental capacity and cognitive styles on science process skills. The findings indicated that there may be evidence to argue that mental capacity and cognitive styles play a important role in development of science process skills. The present study provided a possibility of Neo-Piagetian approach in science education research, and also showed an importance of cognitive development in the performance of science inquiry task.

The purpose of this study was to understand characteristics of eighth graders' conclusions presented in their self-directed scientific inquiry reports. We developed a framework, Analysis of Conclusions of Self-Directed Scientific Inquiry, to analyze students' conclusions. We then compared the conclusions with the inquiry questions students generated to find out whether the questions affected students' conclusions. In addition, we analyzed students' responses from the survey about their perceptions of drawing conclusions. According to the results, the conclusions were characterized into two categories, i.e., scientific basic assumption and scientific explanation. Almost half of the students' conclusions fall under the scientific basic assumptions. Most of the scientific explanations were deductive explanations and inductive explanations. Then, the kinds of conclusions were affected by the inquiry questions because the scientific explanations were made more than the scientific basic assumptions in answering the inquiry questions. Some students couldn't recognize differences between conclusions and experiment results.

In this study, a science writing heuristic class with emphasis on social interaction and tool improvement for 10 middle school students at the National University Science-Gifted Education Center in Jeollanamdo was conducted to investigate the perception of STS (science technology society) relationship and students' perception of the effects of class. After science writing heuristic class emphasizing social interaction and tool improvement, the students became aware of the STS relationships as follows: Science-gifted students have come to perceive that experimental tools and technology contribute to the development of scientific theory, that it is difficult to solve all social problems with only science and technology, and that science is a social interaction activity. In addition, science-gifted students responded that they became aware of the relevance of STS through intensive inquiry conducted on the same subject for several hours, communications with colleagues in another group through peer reviews, communication to solve problems with colleagues in the same group, activities to improve tools in the process of inquiry, inquiry using familiar materials and phenomena. In order for students to effectively recognize the relationship of STS in science-gifted class for middle school students, it is necessary to provide experience to solve problems using various experimental tools, experience to have trial and error in the process of solving inquiry problem under the same subject, experience to improve tools in the process of solving inquiry problem, experience to communicate with colleagues who conduct inquiry activities under the same subject, experience to share the results with other groups, and inquiry activities using familiar materials and phenomena.

The extended science investigations, comprehensive investigations contrasted with exercises of process skill components and cookbook style experiments, should be pursued for giving opportunity of more authentic science activity. The characteristics of the extended investigation tasks were emerged from critical argument on school practical work. And one of important educational objectives in students' investigations is to achieve motivation for investigation. The purpose of this study is to explore how the characteristics of the extended investigation tasks, that is practical context, openness and continuity, affect middle school students' motivation for investigation. On the basis of questionnaire results and students' school science achievement, ten students were interviewed to see the change of motivation for investigation and its causes while they perform two textbook investigations and four extended investigation tasks. Among the interviewees, the students who showed positive motivation for the extended investigations were critical about textbook experiments as they are just confirmations of theories and perceived practical context and openness as the main causes of their positive motivation. The students who showed negative motivation for extended investigations preferred textbook experiments as there was enough guidance from teacher and textbook-centered learning. They recognized the openness of the tasks as a main reason of their negative motivation for investigation. Some students showed negative responses about continuity of the extended investigation tasks but continuity was not recognized as a main cause for their motivation for investigation.

The purpose of this study was to contrive the specific teaching plans based on the frame of 2007 revised science curriculum for applying open-inquiry lesson in real education situation and to research the effects of open-inquiry lesson on the student's science-related attitude, science process skill, and to investigate instructing teachers' cognition about open-inquiry. For this study, two fifth grade classes were chosen, one class was the experimental group, who were taught by open-inquiry based lesson, and another was the comparative group, who were taught by traditional method based lesson. The findings of this study were as follows: After open-inquiry lesson, the experimental group students came to enjoy open-inquiry learning and had the positive thought about it. After open-inquiry lesson, the experimental group marked higher mean score than the comparative group in science-related attitude's field but didn't showed the meaningful difference. On the other hand, in science process skill's field, the experimental group showed the significant higher improvement than the comparative one, especially in the subordinate area of basic science process skill. Finally, teachers who instructed students open-inquiry lesson thought open-inquiry lesson is the self-directed problem solving learning which raise the student's science process skill and interest. And the teachers thought the obstacles to instruct open-inquiry lesson are the lack of the student's cognition about open-inquiry and the insufficient circumstance for open-inquiry lesson. Therefore the teachers argued that the prerequisite for settling open-inquiry lesson successfully is to develope open-inquiry lesson curricula and teaching materials.

The purpose of this study is to understand the elementary student's growth and its implications from the students' experience participating in the science fair by phenomenological study. The results are as follows. First, the students have various experiences. They acquire scientific knowledge and inquiry skills by conducting in-depth experiments, visiting several places, and interviewing experts. They have some experience in writing experiment journals to record the inquiry process in their own language, and presenting their results in public. Second, the students suffer several difficulties while preparing for the science fair. They have some difficulties when the results were not consistent with the hypothesis, or they had to repeat the experiment over and over. They feel burdened in writing the experiment journal. They had a few time to meet friends or for hobbies. Third, the students improve scientific attitude through the science fair, and they receive a positive effect on the affective side. They developed scientific interest, curiosity, cooperation, etc. And they also gained a sense of accomplishment, confidence, friendship, good relationship with teachers, career interest, etc. This study finds out that students participating in the science fair have a lot of experience that cannot be done easily in a normal science class. Even though students confront some difficulties in the inquiry process, they make good progression and feel accomplished. So the science fair is valuable experience for them.

In this study, the 'extended science investigation' was conceptualized as a comprehensive science investigation contrasted with exercise of process and skill component and cookbook style experiment. The extended investigation tasks can be characterized with practical context. openness and continuity. The purpose of this study is to describe the change of students' cognitive engagement while they perform the extended science investigations and to explore how the characteristics of the extended investigation tasks affect the students' cognitive engagement. 128 7th graders attending coeducational school in Seoul were participated in this study. The questionnaire was implemented repeatedly to monitor students' cognitive engagement. And ten students were interviewed to explore the cause of the change of cognitive engagement. The result showed that there was no difference between directive traditional investigations in textbook and developed extended investigations in understanding of the content and whole process of investigations but participants' commitment was increased significantly in the extended science investigations. Especially the extent of students' understanding and commitment became higher in the second half than in the first half of the extended science investigations. The openness of the extended investigation tasks contributed on the increase of commitment. And the continuity of the tasks contributed on the increase of students' understanding in the second half of the extended science investigations.

This study focused on the use of peer assessment activities to investigate its the impact on students' argumentation skills in argument-based inquiry. The participants of the study were 106 10th grade students (four classes). Two classes were assigned to the experimental group, and the other two classes were assigned to the comparative group. The experimental group was taught argument-based inquiry through the application of peer assessment activities. The comparative group was taught argument-based inquiry without peer assessments. At the claim and evidence stage, students were asked to evaluate whether peers' claims fit with the evidence and whether peers' explanation of the evidences validity was sufficient. The quality of argumentation used in the students' writing was different in each group. According to the analysis of the summary writing test, the results showed that the experimental group had a significantly higher mean score than the comparative group in argumentation components, including evidence and warrant/backing. In addition, the experimental group used better multimodal representation including explanation of evidence than the comparative group. The findings showed that argument-based inquiry applying peer assessment activities had an effect on the argumentation skills in students' writing.
