Working alone won't get you good grades, study finds

Working Alone Won't Get You Good Grades
A graph showing interactions between 82 students during the last week of a course. High performing students are in dark blue and form a core where the highest density of persistent interactions can be observed. Mid-performing students are in red and low-performing student sin green. Persistent interactions are shown in thick blue edges, while dotted thin grey edges indicate transient interactions. 

(—Students who work together and interact online are more likely to be successful in their college classes, according to a study published Jan. 30 in the journal Nature Scientific Reports and co-authored by Manuel Cebrian, a computer scientist at the Jacobs School of Engineering at the University of California San Diego.

Cebrian and colleagues analyzed 80,000 interactions between 290 in a collaborative learning environment for college courses. The major finding was that a higher number of online interactions was usually an indicator of a higher score in the class. High achievers also were more likely to form strong connections with other students and to exchange information in more complex ways. High achievers tended to form cliques, shutting out low-performing students from their interactions. Students who found themselves shut out were not only more likely to have lower grades; they were also more likely to drop out of the class entirely.

"Elite groups of highly connected individuals formed in the first days of the course," said Cebrian, who also is a Senior Researcher at National ICT Australia Ltd, Australia's Information and Research Centre of Excellence. "For the first time, we showed that there is a very strong correspondence between and exchange of information - a 72 percent correlation," he said "but almost equally interesting is the fact that these high-performing students form 'rich-clubs', which shield themselves from low-performing students, despite the significant efforts by these lower-ranking students to join them. The weaker students try hard to engage with the elite group intensively, but can't. This ends up having a marked correlation with their dropout rates."

This study co-authored by Luis M. Vaquero, based at Hewlett-Packard UK Labs, shows a way that we might better identify patterns in the classroom that can trigger early dropout alarms, allowing more time for educators to help the student and, ideally, reduce those rates through appropriate social network interventions.

Cebrian's work is part of UC San Diego's wider research effort at the intersection of the computer and social sciences, lead by Prof. James H. Fowler, to enhance our understanding of the ways in which people share information and how this impacts areas of national significance, such as the spread of health-related or political behavior.

How many of these online connections were people simply sharing homework? Sure it leads to a better grade but not a better understanding of the course.

Conversely filtering for high achievers with little interaction can pinpoint geniuses (or cheaters).

Sharing homework doesn't get you good grades. If you live off of that then you'll inevitably flunk your exams.

Working together was prohibited by my university and was seen as an honor code violation, unless it was a group assignment of course.

I dunno if that is such a good idea.
I remember that if our core group during uni hadn't studied together during various maths, physics and other technology courses before the exams none of us would have passed.
