The purpose of the present study was to investigate how two types of cooperative groupworks will affect learners' academic self-efficacy and English achievement in the first graders of Middle school. Experimental class A was done by similar-level groupwork, experimental class B by differential-level groupwork, and controlled class C by whole classwork. In order to accomplish the goals of the study, questionnaires on learners' academic self-efficacy were examined before and after the experiment. Also English achievement tests were done during the experiment. The analytic results of the questionnaires and English achievement tests were like the following conclusions: First, two types of cooperative groupworks were more effective on improving learners' academic self-efficacy than the whole classwork. Second, two types of cooperative groupworks were more effective on improving two levels' (higher and medium) academic self-efficacy. Third, among three types of classworks, differential-level groupwork was the most effective on improving learners' English achievement. Fourth, in case of medium-level learners, differential-level groupwork was more effective on improving their English achievement than similar-level groupwork.

We have compared Korean and American mathematics curriculums in 5 areas: whole number(concepts and its operations); geometry; pattern and relations; measurements; statistics and probability. We have found significant differences in geometry area. Korean curriculums contain simple planar figures (circles, triangles, rectangles, and squres) and some of the spatial figures until 3rd grades. But in America they learn various planar and spatial fugures(cone, pyramid, triangular prism, etc) since the 1st grade starts. They also start the 1st grade by dealing with topological concepts like open/closed, inside/outside, order, etc. As the grade goes on, students learn other geometrical concepts like congruence, symmetry, 3-dimensional views. We also found that American curriculum focuses on students' activities and courages communication through projects, groupwork, journal writing, etc. It's also superior in respects of motivation, and connections with real life and other subjects. Korean curriculum needs more improvements in these aspects. Furthermore for lower graders reviewing sections need to be enhanced for feedback.

Since Lau and Murnighan first introduced the concept of faultlines in 1998, there are many extended studies related to faultlines theory. It is obvious that faultlines theory adds valuable explanations in addition to what numerous previous demographic studies have explored. However, previous research has not been able to fully integrate the characteristics embedded in the workplace environments, and the influence of faultlines in IT industries has yet to be explored. So it is not reasonable and convincing to extend the findings from previous faultlines research to other industries in the global world. In this study, IT related influence is given considerable weight into traditional faultlines theory and the impact of IT-based faultlines is revealed. Our study indicates that IT-based faultlines have negative impact on task conflict, process conflict and relationship conflict, and also have negative impact on individual outcomes such as individual performance and satisfaction. The influence of IT-based faultlines on people s intend to remain in the current organization is found to be insignificant. Our empirical study reconfirmed that faultlines are important indicator in group works and also that faultlines are intimately related to various conflicts and individual outcomes. We hope our research findings would be beneficial to the organizations concerned with effective and efficient group work.

이 논문에서는 동기적 그룹 작업을 위해 기본적으로 갖추어야할 환경인 다자간 멀티 미티어 회의 시스템을 설계하고 구현한 내용을 소개한다. 이 시스템은 공유 자료를 일관성 있게 유지하는 한편 중앙으로의 통신 부담을 줄이기 위하여 중앙 집중 구조(centralized architecture)의 장점을 결합한 혼합형 하부 구조(hybrid infrastructure)와 복제 구조 (replicated architecture)의 장점을 결합한 혼합형 하부 구조(hybrid infrastructure)을 가지고 있다 공동 작업의 관리는 가상 노드로의 중앙 집중형 구조에 기반하며, 오디오, 비디오, 텍스트 등의 실제 데이터는 복제형 구조에 기초를 둔다. 이 시스템은 실시간으로 오디오와 비디오를 처리하기 위하여 동적 큐와 다중 스레드를 이용하였다.

The goal of this study is to explore productive ways to engage students in groupwork using dynamic geometry tasks in online synchronous classroom environments. In particular, we aim to understand the social, mathematical, and technological aspects of student collaboration in virtual spaces. We analyzed how three online groups of students collaboratively worked on dynamic geometry tasks of exploring interactive kaleidoscope applets in Desmos and producing visual representations and written descriptions of geometric transformations used in the applets. The students shared their screens in Zoom as they shared their findings and discussed how to draw and write to represent the kaleidoscopes. We identified three emerging practices of the students collaboratively working on dynamic geometry tasks in online synchronous environments: (a) drawing in response, (b) co-construction, and (c) writing in real time. The emergent practices captured how students socially interacted with others, engaged in mathematical processes, and utilized technology tools. We also discuss inequity in students' participation in collaborative practices in an online environment and possible ways to ensure equitable learning opportunities for online students.
