The purpose of this study is to examine the interactive effects of teaching methods (expository and discovery) and learner's cognitive styles on the retention of learned content in Earth Science three weeks after an instruction is given. The subjects of this study were 1st graders of a boys' high school (n = 185) and co-educational high school (n = 189) in Gwangiu Metropolitan City of Korea. 92 students of the boys' high school and 95 students of the co-ed high school were assigned to the expository teaching group, and the rest of the boys' high school students and the co-ed high school students were to the discovery teaching group. The students were classified into field-independent learners, medium learners, and field-dependent learners based on their cognitive styles. The results of the study can be summarized as follows: First, the discovery teaching was more effective than expository teaching in terms of comprehension and application related to post-instruction retention of learned content. But there was no noticeable difference in knowledge domain. Second, the field-independent cognitive style was more effective than its counterpart, the field dependent cognitive style. Third, in the post-instruction retention test, not so much relevance was found between teaching methods and learner's cognitive style.

The purpose of this study were to develop a tutorial for secondary students to understand of basic concepts of special relativity, which is appropriate for the cognition level of secondary student. We developed the concept evaluation tool and the tutorial material. Result from pretest and post-test are presented to verify the effect of the tutorial for helping student understanding of the concept such as time, event, reference frame, relativity of simultaneity. Secondary student had intense cognitive conflict about the complex concepts such as simultaneity, length contraction and time expansion. This tutorial could be proposed methodology to overcome cognitive difficulty for understanding these concepts.

When mathematicians solve the new problems, they present the solutions to their colleagues for getting the approval. If the solution is accepted, it will be theorems. This phenomenon also happens to classrooms in elementary and secondary school. That is main reason to emphasize mathematical communication activities in mathematics education. This study is aimed to develop teaching and learning model for the improvement of mathematical communication ability, applicate the teaching and learning model to two groups and analyze for mathematical thoughts. This study is a case study of 3rd grader's activities. Eight students, four are group applied the teaching and learning model and four are traditional group. The results have been drawn as follows: First, students in the teaching and learning model group induced richer interactions for student's understanding and investigation when we compare to those of traditional group. Second, students in the teaching and learning model group have the chance to explain their thoughts. And we can observe students to clear on their thought through speaking and discussing. This model makes students to enhance organizing, forming and clearing in their mathematical thoughts and is effective to estimate of students thought for teacher.

Even though identical science textbooks are used in elementary science classes, differences exist in teachers' teaching practices. The purpose of this study was to understand the relationships between elementary teachers' beliefs of science learning and their science teaching practices. An Likert-scale survey and interviews were performed on four elementary teachers to obtain information about the beliefs of teachers in science learning. In order to understand their teaching practices and the relationships between teachers' beliefs and their teaching practices, 2 classes per each teacher were recorded and instruction analyses were performed in the aspects of teaching contents, methods, and learning environments. The results showed that teacher A and B, who held traditional beliefs of science learning, taught their classes mainly based on teacher's explanation. While, teacher C and D, who held constructive beliefs of science learning, reorganized the contents of textbooks and applied various teaching methods and strategies in conducting their teaching practices. There were differences in teachers' beliefs of science learning and teaching practices. These differences in beliefs were related with their science teaching practices.

액션러닝은 팀기반으로 실제의 문제를 해결하는 교수-학습방법이다. 최근 대학에서 액션러닝을 도입하여 대학의 현장적합성을 반영하고, 이론과 실제를 겸비한 교육으로의 변화를 추구하는 움직임이 일어나고 있다. 그러나 학습자들이 강의식 수업 또는 다른 팀기반 학습에 비하여 많은 학습노력에 대한 부담감을 느끼고 있으며 교수자들이 이에 대한 수업의 불성실한 참여 및 불만족을 우려하고 있다. 이에 이 연구에서는 학습자들의 성취목표지향성이 학습과정의 개인 노력과 팀노력 그리고 결과만족을 설명할 수 있을 것이라 보고 이들의 관계를 탐색하였다. 분석 결과 숙달접근의 학습자들은 학습노력을 많이 기울이며 결과에도 만족하는 것으로 나타났으며 회피접근보다는 수행접근의 학습자들이 학습 노력을 많이 기울이며 학습결과도 만족하는 것으로 해석되었다. 따라서 액션러닝을 설계하고 운영할 때, 수업방법의 의미와 학습노력 및 결과에 대한 의미부여와 공감을 충분히 하여 숙달접근이 아닌 다른 성취 목표지향성을 보이는 학습자들을 독려할 수 있어야 하겠다.

In this study, we collected teachers' opinions with regard to the effects of the instruction using analogy generation, the disadvantages of the instruction, the problem-solving methods of the instruction, and the teacher's role in it, and accordingly tried to investigate its effectiveness with the analysis of students' academic achievements and motivation, and through the student's interview, after applying the activities of creating generated analogies, finding the difference between the objects and comparisons, and presenting new-known genetics concepts as the students themselves generated analogies. As a result of a teachers' workshop on instruction using analogy development, it was expected to have a positive effect on students' understanding of scientific concepts in genetics, which were found to be difficult for students to understand in learning biology. Students found analogy examples for concepts in genetics in daily life, compared their analogs to those of peers, and examined inconsistencies between targets and analogs through the process of discussion, which finally led to their correct perception of scientific concepts in genetics. In addition, instruction using student-generated analogies proved to have a more positive effect on improving academic achievement and motivating learning, compared with traditional expository instruction.
