This study is the subsequent study that has the objectives examining the relationships among 'substantive understanding', 'scientific literacy' and 'learning intention' in computer supported intentional learning environments and inquiry ability, variables for affecting knowledge construction derived from the finding out of the former study. As a result, the current study confirmed in CSILE the close correlation between 'the learning intention for scientific inquiry' and 'substantive understanding', between 'the learning intention for scientific inquiry' and 'scientific literacy'. Another result showed that 'scientific literacy' was the most significant predictor on inquiry ability. Base on the result of this study, the present researcher is about to make suggestions to stimulate learners' scientific literacy in CSILE-based inquiry learning.

This study investigated the influences of the cooperative and the individualistic learning strategies on the academic achievement and the attitudes toward science instruction and science by the level of achievement. These two learning strategies endowed students with the responsibility of learning and emphasized student-centered learning which included higher order thinking activities. Cooperative learning group students studied the tasks through small group discussion, and individualistic learning group students solved the same ones individually. In the traditional group. teacher-centered expository lesson was used. The subjects of this study were 7th graders of coed middle school, and were taught about separation of mixture for 10 class periods. Two-way ANCOVA results revealed that the test scores of academic achievement for cooperative learning group were significantly higher than those of individualistic and traditional learning groups. The attitudes toward science instruction and science were also more positive in cooperative learning group than the others. No interactions between the treatment and the level of previous achievement indicated that the cooperative learning strategy was effective regardless of the level of achievement.

Valid and effective science education would require research-based decisions on multiple aspects of science education including policy decisions, science curriculum development, designing teaching resources and methods. However, this has not been the case. In order to provide a research base for science education practices and policy-making, this study reviewed research articles published in major science education research journals in South Korea in the last ten years. The analysis was focused on 8 areas including student conceptions, student thinking, inquiry, affective domain, student ideas about science, science curriculum, students' learning and classroom activity, and student learning in informal settings. General research trends found include: First, science education research conducted for the past decade focused on a certain limited topics/areas. Second, research participants were also limited to certain grade levels or types of students. Third, rather than examining developmental processes descriptive research was prevalent. Fourth, there was a lack of research on developing new areas of study or research on generation of new perspectives, theories or tools. Fifth, many studies were related to school science learning while relatively less studies were about other areas that would impact students' future. Based on the results, we suggest several implications for science curriculum development, policy development, science teaching and learning resources, and others.

As an attempt to consider what to pay attention to in science learning, this study was conducted with the aim of discussing the meaning of science learning as a heterogeneous network. As a result of theoretical investigation, the characteristics of the heterogeneous network were described in three aspects: heterogeneous composition, existence by relations, and construction and change by translation. And it was discussed that science learning also has these characteristics of heterogeneous network. Relating to what to pay attention to in science learning, it was also discussed that science learning as a heterogeneous network requires us to pay attention to the elevation of things, the concept as a punctualized heterogeneous network, and the construction and expansion of heterogeneous network with neonadeuri of 'unripe' and 'ripe'. Finally, several suggestions for the science learning were given.

The present study tries to identify the characteristics of Problem Based Learning (PBL), which affects the development of middle school students' science self-efficacy. Additionally, we have tried to analyze the relationship within those characteristics to demonstrate the processes of science self-efficacy development. In line with this reasoning, we have developed a 20-module, problem-based learning science program and applied this program to 9th grade students (n=17). Two rounds of qualitative interviews have been conducted with each participant after the program, which has been analyzed with the well-documented method by Corbin and Strauss (2007). As a result, three characteristics of problem based learning have been identified to affect the development of science self-efficacy: a) authentic and ill-structured problem sets, b) small group activity, and c) result sharing. Further analysis has revealed that an authentic and ill-structured problem set as a condition precedent of self-efficacy development, while small group activity has worked as an acceleration condition. Lastly, sharing the result works as a transition condition to future interest on science-related activity or choosing science-related majors.

The purpose of this study was to develop 'the problem situations' for the Problem Based Learning(PBL) and to examine it's effects on the science achievement and the attitude towards science learning. Also the students' perception on the PBL model was examined. The topics of the problem situations developed were 'the future energy for reducing the green house effect' and 'the Indonesian forest fire and the El Nino'. The coaching strategies for the PBL were designed and implemented to 10th grade high school students in the science classes, the results are follows; First, the science achievement of the group of PBL is significantly higher than those of group of traditional teaching. Second, the scores of the test of attitude toward science learning of the group of PBL is significantly higher than those of group of traditional teaching. Third, the students' perception of the PBL was positive. Many students have interests and motivations in PBL, some students have difficulties in learning on the PBL. In the students' personal reflection notes the step of a problem statement is the hardest one of the PBL model. Therefore, this study suggests that developing the problem situations based on real context is of great importance for implementing a problem based learning model continuously.

There are complex interactions between personal and contextual features in teaching in a science museum. In order to analyze two teachers' holding classes in a science museum, the CHAT (cultural historical activity theory) was used as an analysis tool in a case study. The analyses of the results revealed that both teachers had difficulties teaching in a science museum due to the contradictions among the factors of subject, rules, community, and division of labor in the activity system. Although both teachers had trouble with similar contradictions, there appeared to be different sets of internalization and externalization of such conflicts depending on the difference in the teacher's perceptions and experiences about teaching in a science museum, the passion and the motivation of the teachers. These suggested that efforts should be preceded to foster the activity system providing both emotional and social supports to teachers in order to activate teaching in a science museum. Taking a teacher training course on teaching in a science museum was also found to fail to function as mediating artifacts. The course should provide not only the experience of executing proper teaching strategies for teaching in a science museum and the feedback on their teaching, but also the guidance on how to lead to optimal expansion of the factors in the activity system.

We incorporated cooperative learning focusing on the 'Crustal Deformation' in five classes of second grade students, at an all-girls' middle school of Gimje city. The groups of cooperative learning were composed of four members of students each, according to the heterogeneous level. We conducted a pretest on the students' preference before incorporating the cooperative learning. After ten weeks of cooperative school work, the students took a post test with the same questions as the pretest. The result of this method greatly impacted the change on the students' scientific preference. It means that the students showed a positive change in their awareness of and participation in science classes, compared to before. However it is difficult to distinguish the differences in their scientific attitude on the recognition about scientists and habits which make them think scientifically. This resulted from the short period of ten weeks which is not sufficient to carry out the study strategy effectively. Surveys of the students on cooperative learning indicates that the middle level students prefer this method unlike the higher or lower level students. we are convinced that they can learn from the students of higher level and are able to help the lower level with the interaction through cooperative learning. According to the result of the survey, the method has some weaknesses; it arouses the high noise levels and consequent disturbance due to verbal interaction and of conflicts due to disagreements when they discuss the process. On the contrary, advantages are developing the students's interest in science class, helping them to learn, creating positive participation in class, and fostering mutual collaboration with other students through cooperative learning.

In this study, we analyzed the effects of science inquiry learning that applies open-ended hypothesis-testing learning model in a high school chemistry class of grade 11 in respect of science process skills, science-related attitude, and appreciation towards science class by cognitive level. Open-ended science inquiry learning activities on Metals and their applications unit in Chemistry I were developed and applied to the treatment groups while the conventional science activities were applied to the control groups. Four classes of 92 students in a high school located in Seoul were assigned into the treatment and control groups, respectively. According to the results in the test of science process skills, the students treated with the alternative experiments emphasizing open-ended hypothesis-testing obtained higher scores in experimental design, data conversion and description, and hypothesis test than those with conventional experiments but not in problem cognition and definition and hypothesis fixing'. There was negative effect on science-related attitude due to increased roles and tasks in the open-ended science inquiry learning activities.
