The purpose of this study was to investigate the effect of cooperative skill training on problem based learning for elementary school science class. Two experiment groups were involved, in which problem based learning model was used and control group, in which traditional instruction was employed. One of experiment groups was trained in cooperative skills before the instruction. The results demonstrated a significant main effect in the scores of achievement and a significant interaction effect between the instructional strategies and learning ability level. The performance of high-level students in the two experimental groups was higher than that of control group. However, the performance of medium and low-level students trained with cooperative skills training was higher than that of students without cooperative skills training. A significant main effect was also found in self-esteem, but there was no significant interaction between instructional strategies and learning ability. Therefore, this study suggests that cooperative skills training is of great importance for minimizing the free-rider effect and increasing collaborative interaction in cooperative learning.

The purpose of this study is to develop instructional strategy which utilizes thinking maps focused on drawing as a measure to enhance science learning motivation, self-directed learning activity and science academic achievement of learners, and to examine the effects of its application. The target unit for this study is 'life cycle of plants' in the fourth grade of elementary school. Two classes of 4th grades of elementary school were selected and divided into two groups. The learners of experimental group have completed thinking map by drawing a picture to express the results to be observed and measured, and used it to arrange the learning contents. The result of this study is as follows. First, it is proven that using thinking maps focused on drawing actually helped improving the motivation of learners to study science. Second, it is proven that this strategy was effective to change their self-directed learning ability in positive ways. Third, it contributed to the improvement of learners' science academic achievement. We found out that the application of this strategy enabled them to enjoy the mapping using drawing, to be immersed in learning, to better recognize the scientific concepts and the structure of learning contents, and to have a positive awareness of the usefulness of thinking maps focused on drawing.

In this study, we have look through the national progress of computer science education in South Korea and analyzed the main subjects and contents of each period. We suggests the ways to evolve the current computer science education in terms of class hours for computer science education, hierarchical instructions, and the limitation of current national curriculum. In South Korea, it has been leaded the computer science education in the world since the it was promoted in earnest since 1995. Based on the recently revised national curriculum, South Korean government are taking efforts to nurture a leader through computer science education in terms of the students' future skills. However, it should be promoted to strengthen the ability of not only problem-solving ability through programming education, but also balanced computing and digital literacy through enhancing the ICT skills. In order to improve the curriculum of computer science education in elementary school of South Korea, a sufficient class hours of computer science education should be secured first.

This study investigated the effects of an instructional method which consists of think-aloud paired problem solving (TAPPS) and mole-map. Three classes (100 students) of a high school were assigned to the control, the TAPPS, and the TAPPS with mole-map (M-TAPPS) groups. Prior to the instructions, students' perceptions of learning environment were examined. Tests of mole conception, problem solving ability, and perception of learning environment were administered after the instructions. Two-way ANCOVA results indicated that the high-level students in the TAPPS group performed better in the conception test than those in the control and the M-TAPPS groups. However, there was no significant difference among the three groups in problem solving ability. The scores of involvement for the TAPPS group were significantly higher than those for the control group.

This study investigated the influences of an instructional method related to problem solving. The new instruction consists of a four-stage problem-solving strategy emphasizing 'planning' and 'checking' stages, and a think-aloud paired problem solving in order to check students' performances in solving problems. Two high school classes (n=91) were randomly assigned to the treatment and the control groups. Prior to the instructions. students' perception of involvement and self-efficacy were examined, and their scores were used as covariates in the analysis. Students' problem-solving ability, perception of involvement. and self-efficacy were examined after the instructions. The test scores of the treatment group were significantly higher than those of the control group in the problem-solving ability and the perception of involvement. However, there was no significant difference between the scores of the two groups in the self-efficacy.

The purpose of this study was to develop an instructional module for creativity(lMC) which was mainly based on a unit ('Sun's family' in the 2nd semester of the 5th grade in the textbook), to verify the effect of this module on Elementary student's creativity and attitudes related to science. The subject in this study was two 5th grade classes from J elementary school located in Busan. One of the group took the lessons which were designed for the IMC, and the other group took the normal classes. The effect of this subject for the experimental group and controlled group was verified by post-test: creativity and attitude related to science. The results of this study are as follows. First, the experimental group showed more creativity than controlled group on the post-test. The IMC was more effective to enhance student's creativity than general class. Second, the IMC was effective to enhance student's creativity without the difference in academic ability level. Third, the IMC was effective to enhance student's creativity without the difference in the gender. Fourth, the IMC was more effective to change student's attitude related to science than general class in the module application.

This study has been performed in order to achieve three objectives. They are as follows: To analyze, based on the research literatures, the nature of scientific inquiry ability and the characteristics of its constitutive elements. To identify inquiry skills and techniques essential to such areas as physics, chemistry, biology. and earth science. To develop instructional models and materials for enhancing inquiry ability on the part of high school students. It was found in the study that the scientific inquiry was interpreted in terms of different meanings according to the viewpoint of the person who are interested in the nature of science. The scientific inquiry has been viewed as the process of knowledge formation, scientific method, inquiry process or process skills depending on the epistemological, methodological, educational perspectives, respectively. It was also identified that certain kind of skills or techniques would be used for inquiry in only one specific area of the science. This study drew a conclusion based on the findings that the skills and techniques will effectively be learned when those are taught with specific knowledge in each area of the science. Reported in this paper are the materials developed, for fostering scienctific inquiry skills on the part of the high school students. The materials were developed, using two themes of a theoretical-abstract chemistry topic and a conceptual-concrete biology topic. Those materals were designed for an experiment and an observation, respectively.

The purpose of this study was to classify types of preconception about the motion of the moon held by middle school students and find out how the lesson applying cognitive conflict instructional model changes their conceptual view of the motion of the moon. A quantitative study was first conducted with 48 ninth graders and then followed by a qualitative study. In the qualitative study, male and female students were organized into groups of five and ten respectively. Students were instructed to observe the motion of the moon about for a month and at the same time were taught via the cognitive conflict instructional model for three class periods. Data were collected from interviews and a questionnaire evaluating the degree of concept development that each student showed. A majority of students were found to hold misconceptions formed from elementary school programs on the motion of the moon. Further, students showed lack of scientific ability to interpret the phenomena of the moon. This study showed that the cognitive conflict instructional model was effective for students to make progress regarding their conceptual views of the motion of the moon. However, it was observed that misconceptions by students may possibly occur when two dimensional figures or miniatures were used.
