Considering the expansion of gifted education and the quantitative increase the Gifted Science Academy, it is important to seek the appropriate methods of mathematics teaching for gifted high school students. In particular, to reflect current trends in mathematics education that the mathematical creativity is being presented as an important educational goal, Now is the time we need student-centered discussion model for regular mathematics classes, not teacher-centered instruction in the way of knowledge transfer. In this study, class model of preparation-based discussion was designed and applied to the regular mathematics classes for the Science Academy. Students participating in this research had a lot of pressure in preparation activities for discussion, but they said that the discussion compared to traditional lecture was mathematically meaningful experience. These findings suggest the implication that class model of preparation-based discussion can be meaningfully applied to the regular mathematics class.

In this study, the multiplicity of synchronous online class discussion activity is explored at conceptual level. From the cultural-historical activity theory (CHAT), each utterance may be considered as a product of the activity system. Alderfer's ERG theory is employed as another theoretical framework for the study. Based on the subject's existence, relationship, growth needs, their class discussion activities constitute four different dimensions: physical/biological, cultural/institutional, social/relational, and cooperative knowledge construction. It is inherent in individual activities and has a different arrangement according to their interests and situations, and at the same time acts as a factor of cooperation and competition among the participants. Through this, collective discussion activities represent complex and dynamic development patterns.

Modern society demands leaders who are trained with competence to not only approach knowledge but also create new knowledge by comprehensively understanding and applying it, and a leader with character and commitment to share one's ideas with others and be able to accept criticisms. In response to these societal changes, universities are increasingly adopting 'small group discussion-based classes with an attempt to develop and strengthen communication skills through reading, writing and speaking. This paper seeks to introduce a case of a math lecture, where discussion-based class was applied to mathematical education, requiring practical problem-solving through an argumentative thought process.

The purpose of this study is to explore the current status and effects of online discussion classes in universities. To this end, a survey was conducted on university students attending a total of four universities in Seoul and Gyeonggi Province to diagnose their perceptions of the operation of online discussion classes and their effects. The collected data were analyzed using frequency analysis, descriptive statistical analysis, cross-analysis, F-test, T-test, and Scheffe test by applying SPSS program. As a result of the study, first, it was found that 'non-real-time recorded lessons' and 'real-time interactive video lessons' were mainly conducted at universities after the COVID19 crisis. Second, in the online class method, 'real-time interactive video class' had a positive effect on 'debate class preference' and was found to be more meaningful. Third, college students recognized participation in online discussion classes as a foundation for expanding creative thinking skills, suggesting that strengthening through smooth communication and exchanges based on learners' sufficient cognitive processes on discussion methods and procedures is more helpful.

The purpose of this study was to investigate the effect of small group discussion and debate emphasizing maker class on elementary school students's science learning motivation and scientific attitude. The conclusion of the study is as follows. First, it was shown that the small group discussion and debate emphasizing maker class had a statistically significant effect on elementary school students's science learning motivation. This is due to the fact that the small group discussion and debate emphasizing maker class stimulates students' interaction, which is why students are more interested in class while solving problems with their peers. Second, it was found that the small group discussion and debate emphasizing maker class had a statistically significant effect on the elementary school students' scientific attitude. This allows students to have enough opportunity to express their opinions through small group discussions and debate, and I think that because they listen to others' opinions when they make new things or make new plans, so they have been able to increase their scientific attitude continuously. Third, based on the analysis of the participant students' opinions on the small group discussion and debate emphasizing maker class, all the participants answered that they were interested in this kind of class and they want to participate in this kind of maker class again. Therefore, it is thought that the small group discussion and debate emphasizing maker class can play a big role in raising the elementary school students's science learning motivation and scientific attitude.

The purpose of this study was to examine how computer conferencing might facilitate collaborative learning for students to engage in meaningful discussion. The participants in this study consisted of the instructor and the students in a graduate level course. Different sources of evidence were used to triangulate the data: in-depth interviews, content analysis of transcripts of discussion, and other archival data including course syllabus, presentation materials, and lecture notes. Participants perceived web-based learning as collaborative process, providing opportunities to share the idea, respect and evaluate different perspectives, and co-construct new insights. Analysis of the data revealed several challenges related collaboration in a web-based learning environment: absence of a sense of community, technical problems, adaptability to different types of learner, and managing the discussion. The data also indicated that a variety of strategies were used to facilitate learning: building a sense of community, technical support, developing instructional methodologies, class size, and design of the content.

The purpose of this study was to examine changes in student writings of claim and evidence after group and class discussions; changes in students' critical thinking; and students' perceptions on an argument-based claim and evidence writing approach. Seventy two grade 11 students from two classes of a high school located in Seoul participated in ten chemistry activities using the argument-based claim and evidence writing approach. Claim scores for 9 topics and evidence scores for 10 topics significantly improved after group discussion. There were also statistically significant differences in claim scores for 7 topics and evidence scores for 10 topics after class discussion. Participant students responded to an open-ended survey that group discussion helped them to figure out the problem context and class discussion guided them to provide with more sufficient evidence. There were also statistically significant increases in sub-scores of the Cornell Critical Thinking Test after the intervention.
