Academic performance and behavioral patterns

In an article just published in EPJ Data Science, Valentin Kassarnig, Sune Lehmann and Andreas Bjerre-Nielsen look into smartphone data of undergraduate students to assess factors influencing social behavior and educational performance.

Everyone has one, everyone uses them: smartphones. In the last decade, technology has fundamentally changed the way we communicate, socialize and interact with each other. But what are the consequences of these changes? How is our behavior affected? What role does the social environment play? An interesting venue to explore these questions is educational research, where the goal is to understand which factors influence academic performance – and how.

In order to shed light on those questions we investigated data collected from 538 students’ smartphones. As part of a larger project (and with explicit consent from everyone involved), we recorded a rich dataset of social behavior: Bluetooth scans, call and text message meta-data, Facebook activity logs, and mobility traces. These data were complemented by personality tests filled by the participants, as well as and administrative data. (More information about the larger project and the data collection process can be found here.)

In our new study, we analyze this dataset in order to shed light on how different aspects of behavior impact the students’ academic performance. We place a special focus on the students’ social environment which was captured across five different channels: calls, text-messages, physical proximity (from Bluetooth scans), Facebook interactions, and Facebook friendships. These ways of interacting are arguably some of the most important channels of communication.

The mean GPA of peers is highly correlated with academic performance

Our analyses revealed that the mean grade point average (GPA) of peers is highly correlated with academic performance. That is, students with high performing friends are very likely to also perform well. Although this effect was consistently observed across all investigated channels, it was most pronounced for calls and text messages, which are considered to be proxies for strong social ties. When we divided students into three groups according to their GPAs we could observe that the dominant fraction of text messages was exchanged among members of the same group:

Distribution of exchanged text messages among students of different performance groups.

So, if you’re not getting good grades maybe it’s because you have the wrong friends?

Unfortunately, things are not that simple. Whether these effects are driven by selection (people select friend that are similar to themselves) or adaption/peer-effects (people grow to be more similar to their friends) still remains an open question.

Social environment strongly influences academic success

However, due to our rich dataset, we were able to compare the importance of various features on academic performance (features about personality, behavior and social network). In our models, the network factors had consistently higher explanatory power than individual factors, underlining the importance of the social environment for academic success.

Among the considered individual effects, class attendance and the personality traits “conscientiousness” and “self-esteem” were found to have significant impact on academic performance.

When we performed a thorough analysis of attendance behavior, we once again found a strong social component, as attendance levels among friends tend to be highly correlated. (A detailed discussion of that topic can be found here.)

Our findings emphasize that academic performance depends to a considerable extent on personality, behavior, and social environment

Finally, we achieved the highest explanatory power when combining all individual and network features. In a supervised learning experiment with the full feature set we achieved state-of-the-art performance without using any information on past performance. Usually past performance is the most important feature in predicting academic success, so that result is quite remarkable.

In summary, our findings emphasize that academic performance depends to a considerable extent on personality, behavior, and social environment. We hope that our work will inspire further studies of the impact of the social environment on academic success, as well as the interplay of individual and network factors.
