This study investigated the effects of assigning cognitive roles, a method that may promote verbal interaction in knowledge-building processes, in small-group discussion for science concept learning. Two classes (62 students) of 7th-graders respectively received a concept learning instruction through small-group discussion with assigned cognitive roles (CR) asking to explain and contradict one's idea and to synthesize and conciliate group's idea, and a concept learning instruction through small-group discussion with no specific assigned roles (NSR), for 9 class periods. After the instructions, the tests of achievement, conceptions, the perceptions on science learning environments, and the perceptions toward small-group discussion were administered. ANCOVA results revealed that low-achievers in the NSR group performed significantly better than those in the CR group. Similar tendency was also found in the scores of the conceptions test. Two groups did not differ significantly in the perceptions on science learning environments and toward small-group discussion.

Purpose: The purpose of this study was to investigate the effects of a small group collaboration learning program through MBTI on nursing professional self-concept and career maturity of nursing college students. Method: A randomized control pre-post test experimental research design was used. There were 30 sophomore nursing students in the experimental group and 30 in the control group randomly assigned and randomly selected from the nursing program of T University in Daegu, Korea. The program through MBTI was developed by Kwon (2002) using a program by Shim and Kim (1997) as treatment. The experimental group received the program through MBTI for 30 hours (2 times a week for 15 weeks) while the control group received no treatment except a series of tests. Measures were the MBTI test, nursing professional self-concept scale, and career maturity scale. The data were analyzed with SPSS Win 17.0 program, chi-square test, and t-test. Result: The experimental group which received the program through MBTI had a higher score of nursing professional self-concept and career maturity change than the control group. Conclusion: A small group collaboration learning program through MBTI was effective in increasing nursing professional self-concept and career maturity of nursing college students.

This study investigated the effect of generative concept maps according to learning achievements and cognitive load. A total of 78 students in the first grade of middle school participated in this study. Before the experimental treatment was implemented, students had to fill out a questionnaire assessing prior knowledge. The study was designed where all the students were presented the same learning contents regarding photosynthesis; however, the two experimental groups were provided with different concept map methods: a learner-generative concept map (GCM) and an instructor-provided concept map (PCM). GCM students were asked to make a concept map by themselves in small groups while they are reading material. PCM students were instructed to study in small groups in order to read the material; however, they were provided a concept map developed by their teacher. The control group (CG) had the teacher present the learning contents in traditional lecture format with no accompanying concept map. The results show that there were significant differences in the achievements among the groups. CG showed higher achievement than both the experimental groups. There was also a significant difference in cognitive load. Although the GCM group did not obtain higher achievement than the other groups, the GCM group showed higher mental effort and lower physical fatigue than the other groups. The GCM group might have invested more effort to find and connect ideas when drawing their concept map with peers which is unlike the conditions for the PCM group and CG. In conclusion, we should consider applying GCM in teaching and learning design in order to increase learning achievement and decrease extraneous cognitive load.

The aim of this study was to investigate how the small group activity system influences individual to form concepts of prime number and composite number through activity theory on learning process of mathematically gifted 5th-grade students. Student's worksheets, recorded video, and interview were gathered and transcribed for analyzing data. Process of concept formation and using symbol behavior were used to derive the stage of mathematical concept from students, and the activity system and stage of concept formation process were schematized through analysis of whole class activity system and small group activity system based on activity theory. According to the results of this study, two students who were in different activity groups separated into the state of semi-concept and the stage of complex thinking respectively, and therefore, social context and the activity system had effects on process of concept formation among the students.

In this study, a concept learning strategy emphasizing social consensus during discussion (SCS) was developed. The instructional effects of this strategy were compared with those of cognitive conflict strategy (CCS) and traditional instruction in the aspects of students' achievement, conceptions, communication apprehension, perceptions of science learning environment, and perceptions of small group discussion. There were no significant differences in the scores of an achievement test. For the students of low communication competency, however, the scores of the CCS group were significantly higher than those of the traditional group. The adjusted mean of the SCS group was higher than those of the other groups in a conceptions test. The social consensus strategy was also found to be more effective in learning concept for those who were more competent in communicating. No significant differences were found in the communication apprehension. The scores of three groups did not differ significantly in the subcategories of 'personal relevance' and 'students' negotiation' of the test of the perceptions of science learning environment. However, the students in the SCS group scored higher in 'participation'. The students in the SCS group perceived small group discussions more positively.

The purpose of this study was to investigate how the argumentations were affected by the students' characteristics in the small groups. The level of self-concept and science related attitude were examined to the eleventh grade high school students in Daejeon city, and the twelve students were participated for this study. The participants were divided into homogeneous groups and heterogeneous groups. The argumentations under the condition of the interpretations about the experimental results in each small group were recorded by VCR. The recorded data were transcribed, then argumentation levels from transcripts in each small group were analyzed through Mitchell's parameters of argumentation. The results of this study were that the group which had higher level of both self-concept and science related attitudes achieved higher level of argumentation. Therefore, it is necessary for teachers to induce students to ask questions and present activities appropriately in order for those who have low self concept and science related attitudes to participate in argumentation.

This study was surveyed concept and consumption for Instant foods by homemakers in Inchon city. The result of study were as follows. 1. In the view of integral numberized high, middle, low, high group reached 19.2%, middle was 50.2% and low showed 30.1%. As higher their ages up, the point was high. 2. Their concept of instant food is close to 'convenience' and 'time saving' but far from 'good for health', 'high nutrition' and 'safe sanitation'. 3. Divied into two groups with positive and negative, which proved their concept of Instant foods as 57.5% positively. Negative group which has negative concept for instant food has a good dietary pattern, Positive group which consists of low ages and high income showed positive attitute for instant fodds. 4. Consumption of bred, noodles and soybean sourecs is little bit higher than other items. Consumption by the group which has low ages, highly educated, having small number of children proved high percentage. Also, the group which has good dietary pattern showed low consumption of instant foods comparing to other group. 5. According to the relation between concept and consumption of the instant foods the group that conceives instant foods positive consumes higher than the group which has negative concept.

The purpose of this study was to analyze the patterns and features of interaction in teacher interviewing with high school students' small group for biology learning. The interactions in variety between the students and between the students and the teacher were made as the interviews with each small group were repeated to feedback for biology learning. The patterns of interaction were categorized into four types by interactive level of interaction among group members and a teacher: leader representation without interaction among students and the teacher(LR, leader representation), interaction among a part of students and the teacher(PSI, partial students interaction), active interaction among students inside the group, but only interaction between the teacher and the leader student(SAI, students active interaction), and interaction between all of the students and the teacher(teacher-students active interaction). Even though complex patterns of interactions were made among the students at the initial stage of insufficient understanding on the study concept, the simple interaction processes were shown as students had gradually completed the understanding on the concept. It was displayed that the interaction in the small group for biology study provides the opportunity to confirm and understand the concept to the students who were poor at the understanding on the concept, and it can influence positively on the mutual creation of study concept.

Among the various fields of Earth Science, especially in Astronomy, we often deal with the change of space-time in an abstract way. Thus, making use of 'Concept Sketches'-simplified sketches that represent the main features, principles, processes and interrelationships of the learning content by using some concise explanations, signs and terms could help the students efficiently learn the phenomena of Astronomy. This study's aim was to check its effects and analyze the results of the lessons that included concept sketches and a discussion about the field of Earth Science in high school. The control group took traditional lessons, while the experimental group did a small-group discussion that used the concept sketches. After the lesson, some students were chosen to answer a questionnaire and go through an in-depth interview. The result of the data shows that the small-group discussion lesson that used the concept sketches helped both the high-ranking and low-ranking students to build concepts and was able to attract students' attention. Moreover, the students produced long-term memories of the content learned through the class discussion, which allowed them to exchange their own thoughts and opinions with other students. Most of all, drawing pictures, a familiar activity, appealed to the students, so they took part in the class eagerly.

This study investigated the effect of small group discussion for science concept learning in cooperative learning environments that encourage verbal interaction with peers upon students' understanding of the concepts at the particulate level, application abilities, perceptions of students' negotiation, and communication apprehension. Two classes of 7th grade at a coed middle school were assigned to the control and the treatment groups. They were taught about change of states and motion of molecules for 7 class periods. Two-way ANCOVA results revealed that the scores of a conceptions test for the treatment group were significantly higher than those for the control group, and that the low-achievers in the treatment group performed better than those in the control group. However, the scores of two groups did not differ significantly in an application test. The perceptions of students' negotiation for the treatment group were more positive, but the scores of the communication apprehension for two groups were not significantly different.
