Social presence is a construct that has attracted the attention of many educational scholars involved in online collaborative learning settings wherein all dialogue happening through text-based asynchronous and synchronous communication channels. The social group members associated with degree participation interaction amongst them and, as such, therefore considered critical variable for learning.

In the current article, development and validation of Work Effort Scale (WESC), a self-report 10-item scale, is described. Data from several samples are used. The three-factor structure (persistence, direction, intensity) WESC confirmed by confirmatory factor analysis reliability well documented. accordance with our expectations, we found positive correlations between self-rated performance global job satisfaction scales work effort.

The main goal of this study was to investigate the association between objectively measured physical activity and academic achievement in adolescents. Students Grades 7 9 ( N = 255) were included. Overall, we found no significant dose–response achievement. However, Grade total volume (Total PA) negatively associated with achievement, while moderate-to-vigorous (MVPA) both mathematics performance. In contrast, Total PA MVPA positively addition, overall followed an inverted U-shaped curve....
