The purpose of this study is to explore the possibility of applying big data analysis to provide appropriate feedback to students using evaluation data in science education at a time when interest in educational data mining has recently increased in education. In this study, we use the evaluation data of 2,576 students who took 24 questions of the national assessment of educational achievement. And we use K-means cluster analysis as a method of unsupervised machine learning for clustering. As a result of clustering, students were divided into six clusters. The middle-ranking students are divided into various clusters when compared to upper or lower ranks. According to the results of the cluster analysis, the most important factor influencing clusterization is academic achievement, and each cluster shows different characteristics in terms of content domains, subject competencies, and affective characteristics. Learning motivation is important among the affective domains in the lower-ranking achievement cluster, and scientific inquiry and problem-solving competency, as well as scientific communication competency have a major influence in terms of subject competencies. In the content domain, achievement of motion and energy and matter are important factors to distinguish the characteristics of the cluster. As a result, we can provide students with customized feedback for learning based on the characteristics of each cluster. We discuss implications of these results for science education, such as the possibility of using this study results, balanced learning by content domains, enhancement of subject competency, and improvement of scientific attitude.

This study is aiming to structure progressive instructional strategy for development of constructivist-thinking into the beginning stage, developmental stage, and advanced stage, then organize multiple choice, completion, descriptive, and essay problems to be suitable for each stage of the strategy, and finally, to evaluate what effects this instructional strategy has on the students' academic achievements and enhancement of their scientific essay writing skills. The results of the study are as follows. First, lessons applying the strategy for developing constructivist-thinking were more effective in enhancing student' academic achievement than the text book-oriented lecture type lessons. In changes in academic achievement, the test group, for both high and low levels, displayed a higher average than the control group, however, changes in the high level was not statistically significant and changes in the low level students were found to be statistically significant. Second, scientific essay writing skills were found to be effective in all levels of the test group and the averages in both high and low groups of the test group were higher than those of the control group and were also found to be statistically significant.

This study examined the instructional influences of MBL programs on elementary school students' science achievement, scientific inquiry skills, and science learning motivation. The perceptions of students and their teacher toward science classes using MBL programs were also examined. The subject of this study was sixty four 4th grade students from two classes. The experimental group engaged in science classes that applied MBL and the control group engaged in traditional science classes based on the textbook and experiment workbook. As results, there was no significant difference in academic achievement, scientific inquiry skills, however, were significantly higher for the experiment group compared to the control group. There was also significant difference in the relevance and confidence, the sub-categories of science learning motivation. In the analyses of students' perceptions toward science classes using MBL, students showed positive perceptions in aspects of interests of science classes, content comprehension, and convenience of experiments. The teacher also showed positive perceptions using MBL in elementary science classes. Educational implications of appling MBL in elementary science classes were discussed.

The purpose of this study was to verify the trends of Korean students'environmental science achievement in recent two international comparative studies, TIMSS-R and PISA 2000. Participants of TIMSS-R and PISA 2000 were 8th graders and 15-years-olds, respectively. The science items in TIMSS-R assess students'science concepts in the science curriculum and science items in PISA 2000 assess scientific literacy in the 21s1 daily life. To achieve this purpose, the 14 environmental knowledge items in TIMSS-R and 16 environmental knowledge items in PISA 2000 were analyzed. As a result of the comparison between Korean- and international percent correct, Korean students showed especially higher achievement in 'resources'or'ecosystem'items. On the contrary, Korean students showed relatively lower achievement in'biotechnology'or'environmental health'items. In general, Korean female students showed lower achievement than their male counterparts. The relationship among environmental knowledge, attitudes, and behavior should be examined more systematically.
