The purpose of this study was to investigate the change of elementary school students' conception on the movement of the moon, after teaching a lesson about the lunar phase which focused on concrete activities. The 396 subjects in this study consisted of intact groups of second, third, fourth, fifth, and sixth grade students. Pre-test and post-test instrument concerning on the conception in the movement of the moon were developed after reviewing the related literature and curriculum. Prevailing conceptions were identified by frequency of each conception. Then, the pattern of change and consistency of each conception were analyzed in comparison pre-test with post-test. To figure out the effect of teaching, the GEFT and the GALT instrument were administered to analyze it by gender, cognition mode and level. SPSS/WIN programs were used to process the data. The result showed that teaching 'movement of the moon' was the most effective in fourth grade. The effect of teaching 'changes in shape of the moon' was effective regardless of their sexes. Teaching 'changes in shapes of the moon' was more effective for the students whose cognitive modes were field-independent, than those filed-dependent. But the improvement by the teaching was not significantly different. The pre-score by cognitive level was significantly high in the order of the formal operational, transitional stage and the concrete operational stage. But the improvement of conception after teaching was high in the order of the concrete operational, transitional stage and the formal operational stage. That is to say, teaching was more effective as the cognitive level lowered.

The purpose of this study was to investigate the effect of learning cycle model on the changes of electricity conceptions of elementary students. Four classes in forth grade of an elementary school in Busan were selected and two of them were served as experimental group and the others as control group. The experimental group were taught the unit of "Light an electric bulb" in elementary science textbook with teaching model based on teaming cycle and the control group with traditional teaching style. The instruction effects were analyzed through pre and post-test results using questionnaire on the electricity. The results of pre-test showed that there was not a significant difference between experimental group and control group at .05 level, so two groups could be regarded as homogeneous. The mean score of experimental group was significantly higher than that of control group on the post-test at .05 level. And within-group comparison revealed that both groups made improvement on the mean score and that the improvement of each group had significant difference at .05 level. Above results said that the teaching model based on learning cycle, which focuses on hands-on activity and considers each student as an active subject, was more effective than traditional teaching style in improving the formation of scientific conceptions on electricity.ectricity.

소프트웨어교육의 중요성이 강조되면서, 초등학생의 컴퓨팅사고력 향상을 위한 다양한 교육이 이루어지고 있다. 하지만 선행연구들을 살펴보면 특정 환경이나 학습자만을 고려한 경우가 많아 학교현장에 적용하는 것에 한계가 있다. 따라서 본 연구에서는 교과서의 내용을 바탕으로 학습자에게 영향을 미칠 수 있는 요인인 교구와 컴퓨팅 사고력에 대한 학습자 수준이라는 특성을 고려한 교수·학습활동을 구성하여 소프트웨어교육을 실시하고, 학습자들의 컴퓨팅사고력 향상도 비교를 통해 효과적인 소프트웨어교육 방법의 방향을 제안하였다. 연구결과 교구와 학습자 수준에 따라서 컴퓨팅사고력 향상에 차이가 있는 것으로 나타났는데 구체적으로 활용 교구에 있어서는 비주얼 프로그래밍과 언플러그드 방식을 활용한 교수·학습활동이 보다 효과적이었으며 학습자 수준에 따라서는 사전검사에서 컴퓨팅사고력의 수준이 낮은 것으로 평가된 학생들이 상대적으로 높은 향상도를 보였다. 이러한 경향은 초등학교 소프트웨어교육에서 교수·학습활동을 구성함에 있어 다양한 학습요인을 고려할 필요성이 요구된다고 보인다.

This research conducted between March and December of 2005 has focused on analyzing a diverse range of educational services provided by English native-speaking instructors teaching in Korea. This study includes quantitative research findings from 238 university students. This dual-semester research study focuses on our most recent Korean EFL (English as a Foreign Language) programs provided for university students who wish to improve their English ability. Many students hope to partake in lectures taught by Native English Speaking teachers (hereafter NS teachers), and many universities are also willing to open additional courses for these students. However, in order for lectures to be most effective, NS instructors need to be appropriately trained or qualified teachers in order to successfully educate their students. Furthermore, NS teachers need to constantly review their teaching styles and strategies to allow for professional development and to ensure an improvement in their teaching methodology. Overall, this research provides whole English lecture views of NS teachers that is data-driven regarding designing, implementing, evaluating, and reforming the education of English taught by NS teachers working in Korea.
