How do online college courses affect student success?

Well, I would argue it depends and research seems to tell this to. Check this graph taken from Clark and Mayers classic book “E-learning and the science of instruction” taken from Bernard et al., 2004:

The graph shows the effectiveness of particular courses of study and the extent to which these courses involved the use of online teaching methods and you can see that the online courses are on both the positive and the negative side of effect sizes.

But a new study by Bettinger et al. shows that it’s maybe a bit more complicated. How do including virtual courses in a curriculum affect students progress in a whole? Well, I think I have some bad news…

Our analyses provide evidence that students in online courses perform substantially worse than students in traditional in-person courses, and these findings are robust to a number of potential threats. We also find differentially larger negative effects of online course-taking for students with lower prior GPA. The results are in line with prior studies of online education in showing that in-person courses yield better mean outcomes than online courses (Figlio, Rush, and Yin 2013; Xu and Jaggars 2013; Alpert, Couch, and Harmon 2016; Streich 2014b; Joyce et al. 2015; Hart, Friedmann, and Hill forthcoming). Our results also suggest one reason why, as other studies have found, for-profit students may have poorer labor market outcomes (Turner 2012; Lang and Weinstein 2013; Cellini and Chaudhary 2014; Darolia et al. 2015; Deming et al. 2016).

The authors try to explain why this could be the case:

Online courses substantially change the nature of interactions between students, their peers, and their professors. First, in online courses, students can participate at any hour of the day from any place. That flexibility could allow students to better allocate time and effort, but could also be a challenge for students who have not learned to manage their own time. Chevalier, Dolton, and Lührmann (2016), studying incentives and student effort, find evidence consistent with this hypothesis. Second, online courses change the constraints and expectations on academic interactions. Professors and students do not interact face-to-face; they interact only by asynchronous written communication. Thus, students likely feel less oversight from their professors and less pressure to respond to professors’ questions. In the standard principal-agent problem, effort by the agent (student) falls as it becomes less observable to the principal (professor): see Jensen and Meckling (1976). Third, the role of the professor is quite different. Online classes standardize inputs, which traditionally vary between professors. For example, lectures are replaced with videos. Between-professor variation in student outcomes may shrink or may widen depending on how professors choose to use the time saved by not lecturing.

Or summarized: relation is key for learning?

Abstract of the study (H/T Jeroen Janssen):

Online college courses are a rapidly expanding feature of higher education, yet little research identifies their effects relative to traditional in-person classes. Using an instrumental variables approach, we find that taking a course online, instead of in-person, reduces student success and progress in college. Grades are lower both for the course taken online and in future courses. Students are less likely to remain enrolled at the university. These estimates are local average treatment effects for students with access to both online and in-person options; for other students, online classes may be the only option for accessing college-level courses.

  1. […] Een studie die ik dit weekend op mijn Engelstalige blog plaatste werd zeer veel gelezen. Uit deze studie blijkt dat online lessen geen positief effect zouden hebben in vergelijking met offline lessen, integendeel. Studenten zouden minder slagen én het zou net voor leerlingen uit zwakkere milieus een groter negatief effect hebben. In een discussie over dit onderzoek via Twitter voegde Herman Van der Werfhorst dit onderzoek uit 2015-6 van Bos et al er aan toe: […]

  2. […] Related to this is a second element: human contact as luxury. If you go to McDonalds you order now your food via a screen. In a more expensive restaurant you will pay extra for a human waiter or waitress. This is a scenario from hell for education in which poor students get the technology while children who’s parents pay more get the actual teachers. It’s not unlike the MOOC’s who were a hope for more democratization of education, but were also actually the opposite or the danger of using taped courses online. […]
