Online discourse reading plays a very important role in collaborative discussions. However, not many studies have examined the influence of group configuration on online discourse note reading. The current study examined note reading workloads and participants' perceptions of the three group configurations (large whole class, small whole class, large with subgroups) in online graduate-level courses from one institute. In this mixed-methods study, we analyzed tracking logs from 25 graduate-level online courses (25 instructors and 341 students) and interviews from 10 instructors and 12 graduate students with diverse backgrounds. Findings suggest that all three configurations had their own advantages and disadvantages in fostering online discourse reading. However, our analysis suggests that the advantages of subgroup discussions in supporting note reading outweigh those of the Small and Large configurations. The overload effects in information reading due to large class sizes can be minimized by dividing students into small groups for discussion purposes. Group configuration into proper-size groups may reduce students' reading loads. Interviewees felt that the waving of small groups into large classes benefited their collaborative discussions. We conclude this paper with a list of pedagogical recommendations and new software features that may help group configuration and enhance learning in online courses. This study may have implications for both practitioners and researchers to seek optimal group configurations to achieve more fruitful online discussions through note reading. 相似文献

Expanding beyond Singapore's boundaries has been a source of increased business for Singapore transnational construction corporations (STCCs). This paper analyses the significance of ownership advantage and disadvantage factors of STCCs in pursuing their international construction business, relative to other ASEAN contractors and contractors from developed countries. Moreover, this study examines if these ownership factors do vary significantly according to firm specific contextual variables in the STCCs such as size, international age, multinationality and extent of specialization/diversification. Based on responses from 22 STCCs, this study has found that the most important ownership advantage factors of STCCs were identified as coming from: (1) information, knowledge, technology and R&D capability; (2) the firm's name and reputation; and (3) management and organizational capability. Relative to established international contractors STCCs have a significant size disadvantage with reference to certain project types. 相似文献
