This research examines computer-supported collaborative learning. Master’s of business administration (MBA) students in an online program were surveyed to examine the extent to which an orientation toward teamwork and the development of group cohesiveness affect overall student learning and the learning that results specifically from team interactions (team-source learning). The results indicate that both teamwork orientation and group cohesiveness predict student learning, with group cohesiveness mediating the relationship between teamwork orientation and student learning. Teamwork orientation and group cohesiveness appear to be equally important predictors of team-source learning. The implications of this research for the use of teams in online distance education are discussed.
The greater reliance of U.S. farm families on off-farm income has implications for the structure of agriculture and the distribution of income within agriculture. Using annual data on farm households from the Current Population Survey, the degree of income inequality for the U.S. and by region is assessed for 1984. The distribution of income among farm families is decomposed by income source. Off-farm income is shown to contribute to higher average incomes and reduce income inequality at the margin, but only in regions where full-time farming predominates. In the Northeast and South, increases in off-farm income increase regional income inequality.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
