This study aims to explore the effect of an appropriate technology program related to water acquisition and purification on scientific attitudes and creative problem-solving skills in elementary school students. Thus, this study developed a learning program related to the appropriate technology composed of 8 sessions, and some were for exploring water acquisition-related scientific principles and the appropriated technology of Warka Tower, and the others were for conducting water purification-related inquiry experiments, such as Life Straw and Drinkable Book, and the last two sessions were for presenting practical tasks through creative ideas and designs and carrying out the relevant campaign activities. For research subjects, this study selected 51 students from two sixth-grade classes, and after modifying the scientific attitude questionnaire and the creative problem-solving skill questionnaire fit for the environment and situation, this study conducted a paired-sample t-test by applying both the questionnaires before and after this program. In addition, while looking into the correlation between scientific attitudes and creative problem-solving skills, based on the post-test results, this study examined relationships between sub-domains perceived by the students after this program was applied. The results can be summarized as below. Out of all the scientific attitudes, curiosity, openness, cooperation, and creativity showed statistically significant results with an increase in the average value when their overall averages of the pre-test were compared with those of the post-test. With creative problem-solving skills, the domain of mastering a specific area and the domain of divergent thinking showed statistically significant results. The correlation analysis results showed that cooperation out of the scientific attitudes had a significant correlation with all the domains of creative problem-solving skills, especially showing the highest correlation coefficient with such sub-domains as critical and logical thinking. All the four domains of creative problem-solving skills showed a number of significant correlations with the sub-domains of scientific attitudes. Through the research results above, this study has several implications on how and where to apply such appropriate technology-related topics in the future and various responses from students.

This study examined how specific aspects of epistemic cognition are developed in elementary students during modeling activities, using the Apt-AIR framework. The study focused on a class unit titled 'Shall We Find Out What the Landscape of a Riverside Looks Like?' which is part of the land chapter in the third-grade Korean elementary science curriculum. Ambitious Science Teaching (AST) was applied as a teaching strategy to enhance students' model construction. Seven science classes were conducted in line with the core practices of AST, with 29 elementary school students participating in the study. The classes were organized into four stages: initial model composition, inquiry activity, group model composition-sharing, and final model construction. The class activities at each stage were analyzed using both the AIR model, i.e., epistemic aim and value (A), epistemic ideals (I), and reliable epistemic processes (R), and the multi-faceted framework for epistemic thinking from the Apt-AIR framework. The results of the study revealed that in science classes emphasizing modeling activities based on the core practices of AST, the elementary students progressively developed more sophisticated explanatory models that included causal relationships explaining the topographic differences between the upstream and downstream sections of a river. This result was due to their engagement in constructing initial models to describe phenomena, supplementing the initial models using data collected in the model experiment, and participating in discussions to share and evaluate group models. Additionally, from the perspective of the Apt-AIR framework, the aspects of epistemic cognition demonstrated by the elementary students in their modeling activities were appropriate for engaging with cognitive processes related to epistemic aims and values, epistemic ideals, and reliable processes. The other four aspects of the Apt-AIR framework, however, were not performed as effectively. In particular, the application of reliable epistemic processes for knowledge construction required more improvement.

The purpose of this study was to construct an issue-centered discussion instructional model for Home Economics and to determine its effect on middle school students' critical thinking. The research questions were posed as below. 1) The object and content of home economics in the 7th national middle school curricula are analyzed to sort out possible issues. 2) An issue-centered discussion instructional model is constructed to be applicable to middle school home economics class. and a lesson plan is prepared. 3) The effect of the issue-centered discussion instructional model developed in this study on student critical thinking faculty is examined. The findings of this study were as follows : First. seven criteria were selected to determine what types of issues were applicable to home economics lesson. Based on the selected criteria. 41 themes of issues were extracted from the 7th middle school textbooks. and their content validity was verified. Second, an issue-centered discussion instructional model was designed to deal with four themes in eight sessions in the procedure of problem raising, confirming, term defining. tentative alternative selecting, data gathering. discussing/critical approaching. and selecting/concluding. Third, two different third-year classes of K middle school in the city of Busan that consisted of 75 students were respectively selected as an experimental group and a control group, and the experiment was conducted in eight sessions for five weeks to see whether the teaching plan brought any changes to the critical mind of the students. The experimental group exposed to the issue-centered discussion lesson made a significant progress in critical thinking faculty(P<.05). In particular. that instruction gave a favorable impact on demonstration evaluating(P<.05). one of the critical thinking subfactors. When the students were asked to assess the issue-centered discussion lesson. most of them viewed it favorably. In the future, more research efforts should be dedicated to enhancing the practical applicability of issue-centered discussion instruction in home economics education. developing good evaluation tools about critical thinking faculty and finding out how discussion instruction could be conducted more efficiently.
This study configured an integrated math program in which young children can directly participate through storytelling, a teaching technique that has recently earned great popularity. The purpose of the study is to have a positive effect on their mathematical disposition and self-efficacy through the adoption of this program. The program consists of the following five themes: 'understanding of the basic concept of numbers and calculation', 'understanding of the basic concept of space and figure', 'basic measurement', 'understanding of rules' and 'basic data collection and result representation'. The specific activities for each theme planned and executed according to a detailed plan were designed for 20 classes including integrated activities such as story sharing, fine arts and games. The study's participants were 48 five-year old children. The result of the research was that the experimental group's mathematical disposition and self-efficacy score was significantly higher than the control group. The Storytelling-Integrated Math Program was effective in young children's cultivating mathematical disposition and improving self-efficacy. Considering the reality that there has been some confusion and difficulty in carrying out storytelling math and an integrated math program based on the NURI curriculum, it appears that this study could provide a specific and effective teaching-learning program to teachers who want to introduce a program like this.g
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.
The purpose of this research is to investigate the participant satisfaction of public educational programs being carried out in Natural History Museum and the contribution of these programs to normal school education and to suggest an improved framework for public education programs in Natural History Museum. For this study, we choose Seodaemun Museum of Natural History in Seodaemungu, Seoul, in which more than 30,000 students have participated in the educational programs for the last 6 years. This museum has been providing more than 60 science education programs every year. Based on a public census among participating students and accompanying parents, we investigated the satisfaction ratings of education programs provided by Natural History Museum and their contribution to school science education. The result of this study can be summarized as follows: (1) It is desired to have the education program contents well connected to the exhibits of the Museum and to increase time for experiments and practice. (2) It is required to improve the ease of access and to enhance the public awareness about the program itself. (3) The biggest consensus among participants is that the education programs by Natural History Museum should be focused on strengthening the research ability and scientific attitude rather than on acquiring knowledge, which will contribute to school education more significantly in the end.

The study aimed to evaluate an activity-oriented extracurricular science program as informal science education through the assessment of opinions of student participants and lead-students and lead-teachers who organized the program. An 'Exciting Science Fair' was designed by science teachers and students and provided for 857 students for two days in early 1998. Students chose a course of science activities designed by different levels of student knowledge and interests. During their own science activity courses, the participating students were grouped as pair of two students and guided and facilitated by lead-students. A survey instrument was developed by researchers and asked respondents' opinions of 121 participating students, 72 lead-students, and 19 lead-teachers to the significance of program goals, degree of goal achievement, and program planning and management system before and after the program. It was found that most student participants, lead-students and lead-teachers satisfied with the efficiency of the program. However, it was recommended that the program should place more emphases on engaging student participants in science activities, strengthening scientific inquiry through activities, and increasing science content related to student daily life. It was also suggested that advertizement of the program be publicized in advance through media, an effect teaching-learning strategy for lead-students be developed, and collaboration among lead-students and lead-teachers be improved.

In this study, the first experience of the whole research process of a novice scientist (student A) who participated in the Undergraduate Research Program (URP) was analyzed. The data were collected through observation, interviews, and document analysis with the cultural historical activity theory being used as a theoretical lens. At the beginning of novice's research, the mentor guided him in setting a research goal and provided mediating artifacts. Student A formed a research team based on the vertical relationship without a shared mental model. Two major contradictions occurred and they were the sources of changes of student A's activity system. The first contradiction was between the mentor's educational philosophy and the mentee's educational needs, which was resolved in a way that student A asked and used the mentor's network to obtain his needs about task-specific details. The second contradiction arose because the team members wanted horizontal relationship while student A wanted to stick to the vertical relationship. After student A accepted the opinions of the team members, they cooperatively changed the division of labor in the activity system. Student A decided to become a scientist and not a physics teacher, even if his major is physics education after finishing his URP research process. His URP experience also created and expanded his network in the academic field, and his negative attitude toward collaboration changed positively. Through the analysis of the structure and changes in the activity system of URP research, implications for instructional method and support system of the apprenticeship can be obtained.
