The purpose of this study is to investigate the effect of learner-centered instructions using instructional materials which are developed in the light of constructivism and implementing practices of the instruction. According to the result of Recall Test, experimental group and comparing group have not statistically meaningful difference. However, in the result of Generation Tests which include the contents not dealt with during the experiment treatments, the two groups have statistically meaningful difference. It can be drawn from the result that students who take learner-centered instruction are in a good readiness for learning of the contents which will be addressed in future.

The purpose of this study is provides an implication of further teaching learning process by analyze the common and difference and characteristic of mathematical self-efficiency between three peer tutoring groups discourse in the mathematical teaching leaning process that use peer tutoring. To achieve this goal, three groups formed that consist of one peer tutor who received a first grade of mathematic achievement and one peer student. Peer student of each group is divided into high grade, middle grade, low grade of mathematic achievement. Then analyze the discourse in the exponential function problem solving process. Based on the results of study, this paper provides a concrete example of merit of peer tutoring on the peer tutor. Result of study also provides a practical help to make a peer tutoring group by considering a difference of grades between peer tutor and peer student. Because there is a possibility of mutual discourse on the tutoring group that consist of similar grades.

The purpose of this study was to investigate the effects of the group reward and cooperative skill training on science achievement and learning motivation of elementary students. 3 classes of the 6th grade students were selected from an elementary school in Busan. Group I took traditional cooperative learning (TCL), group II took cooperative learning with competitive group reward (GR), and group III was trained in cooperative skill (CS) before cooperative learning. Students were taught about 'weather forecast' for thirteen periods and problem-based learning steps were applied in each class. The results from this study were as follows: First, there was an interactive effect between the treatment and achievement level in the science achievement test scores. In the case of high-level students the group reward was more effective than cooperative skill training on the science achievement; on the other hand, in the case of low-level students the cooperative skill training was more effective than the group reward on the science achievement. Second, there was no interactive effect between the treatment and achievement level in the motivation scores.

This study investigated the effects of grouping (group composition) in cooperative learning strategy upon students' achievement, the attitude toward science instruction, the perception of learning environment, and the self-esteem. Three different groups were used in this study. For the two treatment groups with cooperative learning strategies, High-Medium-Low ability grouping (HML) and High-Low I Medium-Medium ability grouping (HL/MM) were used. For the control group, traditional instruction was used. Before the instructions, the short-version Group Assessment of Logical Thinking, the test of attitudes toward science instruction, the perception questionnaire of learning environment, and the questionnaire of self-esteem were administered, and their scores were used as covariates. Mid-term examination score was used as a blocking variable. After the instructions, a researcher-made achievement test consisting of three subtests (knowledge, understanding, and application), the test of attitude toward science instruction, the perception questionnaire of learning environment, and the questionnaire of self-esteem were administered. The ANCOVA results revealed that there were significant interactions between the instruction and the level of prior achievement although there were no significant differences in all subtest scores of the achievement test. The high-level students in the HL/MM cooperative group performed better than those in the control group and the HML cooperative group. The low-level students in the HL/MM cooperative group also performed better in the subtest of knowledge than those in the other groups. However, the medium-level students in the HML cooperative group scored better than those in the control group and the HL/MM cooperative group. Significant main effect was also found in the perception of learning environment but not in the attitude toward science instruction and self-esteem. The cooperative groups, regardless of grouping, exhibited more positive perception than the control group.

The purpose of this study is to investigate the effects of the learning environment on the learning achievement of the learners and to improve the learning achievement of the learners while accepting the fact that it is difficult to change the class environment in which the middle and large group. Among the learner's positive and cognitive factors, we examined the factors that can classify learners into homogeneous groups in programming learning. The difficulty level of the learning contents influenced factors that classify the homogeneous group, and the factors were analyzed by dividing the intermediate difficulty and the final achievement. In addition, we examined the factors that affect the difference between two grades in order to analyze factors affecting steady learning regardless of difficulty level. It was found that the learners' personal motivation influenced the learning achievement of easy learning contents, and the performance self - efficacy had influence on the learning achievement and achievement of difficult learning contents.

The purpose of the research is to assure the effect of learner-centered instruction driven from the constructivism. The school in participation of the research is one of them called "achievement increase intensive school". Quasi-experimental design is applied for the research. Some conclusions were drawn from the research. Experimental group' achievements of both "learned contents" and "none learned contents" were more superior than ones gained from comparative group with statistically significant difference. The results implied that learner-centered instruction is effective for students who have low achievements from standards tests.

Although there was an introduction of the class with in mind learner's individual learning ability as a method improving problems of the class which consists of students with various kinds of levels, it was a burden to both teacher and students because of many realistic problems. In this paper, we investigate the efficiency of peer tutoring teaching method which is the one that students having a superior ability for learning become peer tutors and they teach other peer tutee under the teacher's guidance and supervision. After we apply the class-wide peer tutoring to some sophomore classes, we obtain that this teaching method affects positively the students's learning achievement and learning attitude in mathematics class. In particular, we obtain that the peer tutoring is more effective in three to one group than in one to one group.

This paper examines the perception of Korean phonemes by Egyptian learners of Korean and presents the learnability gradient of Korean consonants and vowels through High Variability Phonetic Training (HVPT). 50 Egyptian learners of Korean (27 low proficiency learners and 23 high proficiency learners) participated in 10 sessions of HVPT for Korean vowels, word initial and final consonants. Participants were tested on their identification ability of Korean vowels, word initial consonants, and syllable codas before and after the training. The results showed that both low and high proficiency groups did benefit from the training. Low proficiency learners showed a higher improvement rate than high proficiency learners. Based on the HVPT results, a learnability gradient was established to give insights into priorities in teaching Korean sounds to Egyptian learners.

This study investigated the effect of the grouping method in cooperative learning applied to chemistry concept learning. Two grouping methods used were the HML (High-Medium-Low) and the HL/MM (High-Low/Medium-Medium) ability grouping. Three classes (N = 136) at a high school in Seoul were randomly assigned to the control and the treatment groups. Before instruction. the test of attitude toward science instruction, the perception questionnaire of learning environment consisting of three subtests (participation, conflict, and competition), and the questionnaire of self-esteem were administered, and a mid-term examination score was obtained. These scores were used as covariates. After instruction, the three tests administered before instruction and the conceptions test were administered. Two-way ANCOVA results revealed that there was a significant interaction between the treatment and the level of previous achievement. The low-level students in the HL/MM cooperative group performed better than those in the other groups. The cooperative groups, regardless of the grouping methods, exhibited more positive perception than the control group at participation subtest of the perception questionnaire of learning environment.
