Research: Students’ online and offline social networks can predict course grades

Researchers at the Ben-Gurion University of the Negev’s (BGU) Social Networks Security Research Group have developed a method to predict how well or badly a student will perform in an academic course by looking at social relations both online and offline. It can look a bit strange that they extrapolated some of the offline interactions through their online interactions, but there is some smart thinking. Btw, don’t use this research to argue that you better team up a good student with a lesser one.

From their press-release:

The researchers analyzed data from a BGU course that included assignments submitted online and Web site logs (containing 10,759 entries) to construct social networks of explicit and implicit cooperation among the students. The implicit connections are used to model all the social interactions that happened “offline” among the students: e-mails with questions, conversations in the lab while preparing the assignments and even course forums.

“These connections were very important, as we sought to model the social interactions within the student body,” co-author and Ph.D. student Michael Fire explains.

In addition to analyzing the online submissions of the students who had to work in pairs or in groups, they also tracked login time and computer usage. For instance, if two students submitted their assignments from the same computer, it was a likely indication that the two had worked together to complete the assignment. If two students submitted assignments from different computers, but one right after the other on more than one occasion, the authors gave a value to that data, as well.

“One explanation for what we discovered is that your friends influence your grade in the course, so, if you pick your friends well, then you will get a higher grade,” Fire says. “Alternatively, social networks in courses offer conditions whereby good students will pair with other good students and similarly weaker ones will pair with other weaker students.” he continued.

Abstract of the research paper, freely available here:

In this paper, we propose a novel method for the prediction of a person’s success in an academic course. By extracting log data from the course’s website and using network analysis, we were able to model and visualize the social interactions among the students in a course. For our analysis, we extracted a variety of features by using both graph theory and social networks analysis. Finally, we successfully used several regression and machine learning techniques to predict the success of student in a course. An interesting fact uncovered by this research is that the proposed model has a shown a highcorrelation between the grade of a student and that of his “best” friend.

Clickers from the seventies

Do you know clickers? These are little devices so all students (or groups of students) can participate during class even in a big auditorium. Seems pretty high tech, no?  Ok, one could argue that why we should botter with an extra device if most students have their cellphone (often nowadays a smartphone) or a laptop with them?

But maybe it beats the old-fashioned way Dylan William does it in the famous Classroom Experiment-documentary, although those little whiteboards proved quite effective (if not for some brighter students)?

But clickers are not at all that new, actually, as we can learn from a blogpost by Larry Cuban with the bit provocative title ”Why Do Smart People Do Dumb Things? Thinking about School Reform“. Stanford University had them already installed in the seventies!

The amphitheater-shaped room with half-circular rows looked down on a small stage with a lectern, a massive pull-down screen, and two large monitors suspended from the ceiling. At most of the individual seats was a small punch-button pad called the “student responder.” The responder contained the numbers 1-10 and letters T and F.

But were the responder a big success? Well, no, not at all.

Cuban argues now that we don’t seem to learn from our former insights. This might be true, but he takes a big leap when comparing responders with MOOC’s. Still one can ask ourselves indeed if we don’t put too much hope into MOOC’s, just as we have done in School TV, Smartboards and maybe it’s too early to write tablets? This doesn’t mean these devices can’t play an important role in education, and actually quite often they do, but a role is not the same as the game-changing element we like to expect.

The Perfect Storm for Universities

Even if universities may look well on the surface there is an increasing (and justified) concern that all will change soon. New data and analysis increase the anxiety that the current monopoly of higher education will be lost and just few universities will survive. No one knows which, how many or even if any university will have the chance to celebrate the middle of this century.

Please refrain from the use of digital native (again)

Prenzky doesn’t use it anymore. Research has shown over and over again that it isn’t true, but people keep on calling young people digital natives. Well, some more (literature) research by Erika Smith (University of Alberta) giving arguments to stop doing this (HT @wrubens). She sees 8 claims in the digital natives discourses for which she sees little proof:

  1. Possessing new ways of knowing and being. A persisting claim within digital native discourse is that there is an urgent need for educational institutions (administrators, educators) and parents to recognize and adapt to digital native learners who possess new learning styles or different ways of knowing and being. This viewpoint sees current problems with education as a part of old ways of schooling (i.e., old ways of being and knowing), often associated with digital immigrants.
  2. Driving a digital revolution transforming society. Another dominant claim is that there is a pressing need to acknowledge and accept a digital revolution transforming society. Many argue that this revolution is especially evident within and important for higher education.
  3. Innately or inherently tech-savvy. Within digital native discourse, students are seen as innately or inherently tech-savvy, desiring and using digital technology in all arenas, as opposed to older educators who lack tech-savvy.
  4. Multi-taskers, team-oriented, and collaborative. Net generation students are often said to be multi-taskers, team-oriented, and collaborative.
  5. Native speakers of the language of technologies. Purported as native speakers of the language of technologies, digital natives are often seen as having unique viewpoints and abilities, especially regarding their unique aptitude for the language of technology.
  6. Embracing gaming, interaction, and simulation. According to digital native claims, gaming, interaction, and simulation (i.e., multi-linear, visual, virtual environments) are both embraced by and well-suited to the Net generation.
  7. Demanding immediate gratification. The Net generation is often portrayed as demanding immediate gratification, with short attention spans and no tolerance for delays. However, even some digital native proponents dispute this argument, such as Tapscott.
  8. Reflecting and responding to the knowledge economy. Proponents of digital native notions often present a strong relationship between needs of the Net generation and the knowledge economy (i.e., students as consumers, demanding customer satisfaction), specifically within the context of the Information Age.

Smith concludes:

Despite a growing body of recent evidence challenging such notions of students as digital natives, these ideas remain influential. As a learner and practitioner who (to some) may also be considered a part of the Net generation, I do see important and well- warranted educational innovations occurring with the use of emerging technologies. However, by mapping the key digital native arguments shaping higher education technology research and practice over the past decade, I am advocating for further discussion and analysis of the varied themes that continue to form the many facets of this debate.

Abstract of the research that you can download freely here.

More than a decade after Prensky’s influential articulation of digital natives and immigrants, disagreement exists around these characterizations of students and the impact of such notions within higher education. Perceptions of today’s undergraduate learners as tech-savvy “digital natives” (Prensky, 2001a), who both want and need the latest emerging technologies in all learning situations, continue to dominate the discourse in educational technology research and practice. Popular yet controversial conceptions of digital natives continue to be embedded within the assumptions of several contemporary research studies on student perceptions of emerging technologies, seemingly without regard for a growing body of evidence questioning such notions. In order to promote critical discussion in the higher education community considering potential directions for further research of these issues, especially within the Canadian context, the purpose of this review of recent literature is to analyze key themes and issues emerging from contemporary research on the Net generation as digital natives.

A Gift for You: Why Education Matters

Reblogged from Diane Ravitch's blog:

This article is a Christmas gift from me to you.

Leon Wieseltier of The New Republic has written one of the most eloquent explanations of why we need teachers, schools, and universities.

At a time when we hear hosannas to online learning, home-schooling, inexperienced teachers, the business model of schooling, for-profit schools, and the commodification of education, this is bracing reading.

Great piece. Does remind me of the question 'what do teachers make?' The difference, off course!

Raising kids by Triple P, not that sure if it works…

This week Renske Schappin presented her PhD at the University of Utrecht in which she examined the effect of the Triple P-approach with 2-5 years old preterm born children with emotional / behavioral problems which has proven to be quite popular. She compared 2 groups of children with behavioral problems from which the parents and educators of one group  received Triple P-training, the other group didn’t. (Source in Dutch)

When compared, Schappin couldn’t find any significant effect of the approach.

If you wonder what Triple P is:

Wikipedia describes Triple P as

a multilevel parenting intervention with the main goal of increasing the knowledge, skills, and confidence of parents at the population level and, as a result, reduce the prevalence of mental health, emotional, and behavioral problems in children and adolescents. The program is a universal preventive intervention (all members of the given population participate) with selective interventions specifically tailored for at risk children and parents.

A Triple P website for parents advertises

the international award winning Triple P – Positive Parenting Program®, backed by over 25 years of clinically proven, world wide research, has the answers to your parenting questions and needs. How do we know? Because we’ve listened to and worked with thousands of parents and professionals across the world. We have the knowledge and evidence to prove that Triple P works for many different families, in many different circumstances, with many different problems, in many different places!

The Triple P website for practitioners declares

As an individual practitioner or a practitioner working within an organisation you need to be sure that the programs you implement, the consultations you provide, the courses you undertake and the resources you buy actually work.

Triple P is one of the only evidence-based parenting programs available worldwide, founded on over 30 years of clinical and empirical research.

Earlier this year, in November, Scottish researchers described how much of the earlier proof of the positive effect of the approach evaporates when they examined the evidence. (check their systematic review and meta-analysis)

On PlosOne James Coyne takes a closer look at the work by Philip Wilson and his Scottish colleagues and discovered that they found an important weakness in the research but to hi, they even underestimated how big the problem is: “Wilson and colleagues pointed to serious deficiencies in the body of evidence supporting the efficacy of Triple P parenting programs, but once we exclude underpowered trials, there is little evidence left.”

The thing is, just as with many of such programs a lot of money is involved and it’s sometimes very difficult to criticize. Schappin stated that she found it very difficult to get her research published as the major journals which she perceived as a publication bias, something that Coyne and Wilson also mention of sorts. I don’t know for sure if that’s the case of course. What I do know that for an expensive program, there is reasonable doubt and further research is at least advisable before investing?
