Online Science Instruction Can Promote Adolescents' Autonomy Need Satisfaction: a Latent Growth Curve Analysis.

This research examined the differential motivational effects of a pre-college science enrichment program delivered in both online and in-person learning formats. Using self-determination theory as a guiding framework, we hypothesized that (a) students would exhibit growth in their perceived satisfaction of needs for autonomy, competence, and relatedness, (b) online learning would be associated with greater growth in autonomy, and (c) in-person learning would be associated with greater growth in both competence and relatedness. Using a sample of 598 adolescent participants, results of latent growth curve modeling indicated that satisfaction of the three needs grew unconditionally over the course of the program. However, format type was unrelated to growth in need satisfaction. Rather, this effect was found to be conditional upon the type of science project undertaken by students: astrophysics students exhibited significantly greater autonomy growth when receiving online instruction than did biochemistry students. Our findings suggest that online science learning can be just as effective in motivating students as in-person learning provided that the learning tasks are conducive to remote instruction.

Facebook and romantic relationships: intimacy and couple satisfaction associated with online social network use.

Online social networks, such as Facebook, have gained immense popularity and potentially affect the way people build and maintain interpersonal relationships. The present study sought to examine time spent on online social networks, as it relates to intimacy and relationship satisfaction experienced in romantic relationships. Results did not find relationships between an individual's usage of online social networks and his/her perception of relationship satisfaction and intimacy. However, the study found a negative relationship between intimacy and the perception of a romantic partner's use of online social networks. This finding may allude to an attributional bias in which individuals are more likely to perceive a partner's usage as negative compared to their own usage. Additionally, it was found that intimacy mediates the relationship between online social network usage and overall relationship satisfaction, which suggests that the level of intimacy experienced in a relationship may serve as a buffer that protects the overall level of satisfaction.
