This last year, I formed my graduate research lab at Iowa State University with the recruitment of Jeff Rokkum, my Ph.D. student in HCI, Elizabeth Longnecker, my Master’s student in HCI, and Darcy Besch, my co-advisee from Sociology. We’ve been busy writing papers, studying how social media and other communication technologies impact student learning, and dreaming up new ideas for future studies.
We’re excited to share our progress with you through our new lab website :
On the website, you’ll find bios of my current lab students, short descriptions of current projects, lists of publications and presentations, and some dope playlists. Our lab mascot, Rainbow Disco Pony, hopes you’ll visit us soon!
The team would appreciate your ideas as our research lab grows and begins new projects. Feel free to leave comments or questions or send us an email to our lab address (email@example.com) or @rainbwdiscopony on Twitter.
Thanks to: Kara Cipolloni & Josh Tenney for our beautiful portraits and team photos and Elizabeth Longnecker for her tireless work in creating the website.
As you may have guessed, my vacation is over. I survived. I endured another winter break away from technology. Did I miss an important email? Yup, I certainly did. Although one can ponder what “important” actually means in this case. You know those important emails pertaining to life/death situations? Yeah, that never happens. So while it was stressful to think about deleting all of my emails while I was away, all of my work was still intact, waiting for me right where I left it. The wonderful part? No stressful email backlog. And you know what else? Every time I take a break from technology, it gets a little easier. After day one, I no longer felt my phone tugging at me in the background. I was able to fully enjoy every moment that I spent with my son. We even saw Star Wars spoiler-free thanks to my avoidance of social media!
It was a proper break. It was relaxing. I was centered and calm. I slept well. When I got back, I had to hit the ground running because it was the week before the semester started. I lamented having to “come back to technology” and wished I could have taken a break for longer. The Iowa State College of Human Sciences even did a story about it.
As those of you who follow my work know, I believe in the social benefits of technology. However, it is important to understand how technology affects you and your workflow. I’ve found what works for me. Twice a year, I deactivate my Facebook account, ignore my Twitter and my Instagram, empty my inbox, and turn off all distractions. And every time I do this, I come back feeling recharged, refocused, and ready to tackle a new semester (yeah, my students think I’m nuts because of how excited I am to teach stats and methodology).
So take a vacation, a real vacation. You’ve earned it.
P.S. Stay tuned for some new publications/projects from my newly-formed research lab. Also, keep your eye out for the unveiling of our lab website
tl;dr : If you email me between 12/16/15 and 1/8/16 I won’t get it.
Those of you who have been following my work for a while know that every year I take two of what I’ve affectionately termed “vacations from technology.” Usually once during the summer and once in December, I turn off all the digital things like email and social media. I won’t lie: the first day is really really hard. On that first day, I usually check my phone multiple times expecting there to be a new message or notification. However, after that brief adjustment, it’s truly a transcendent experience. No, I’m not joking. I’m a big believer in David Allen’s thesis that email and other technologies exert a pull on your subconscious mind making you feel like there’s more to do. Because if you aren’t vigilant you might miss that ever important email. You know – the one that if you miss might cause you to suffer career, health, or social consequences.
So I’m taking a break from that pressure in order to recharge and recenter so that I can come back to my work at full emotional and physical operating capacity. To that end, I will not be checking emails during my break and all emails I receive during that time will be deleted. Coming back to an inbox that takes me at least a week to process defeats the core purposes of my break. Therefore, if you want to reach me via email, make sure your email gets to me before Wednesday December 16 or after Friday January 8, 2016. The other important bit is that I will be deactivating my Facebook during that time. If you don’t know how that works, it’ll look like I’ve deleted my Facebook profile until I sign back in again in January.
Over the last couple of years, I’ve been researching how real-time behavioral data, collected unobtrusively through technology, can predict learning outcomes. As part of this line of research, I’ve recently published the paper Predicting course outcomes with digital textbook usage data in The Internet and Higher Education.
The study used data collected from student engagement with digital textbooks in order to predict course grades. Two measures of student engagement with the texts were analyzed: an engagement index that was calculated through a linear combination of the number of pages read, number of times a student opened their textbook, number of days the student used their textbook, time spent reading, number of highlights, number of bookmarks, and number of notes. The second analysis included the individual components of the engagement index.
Major Findings: The engagement index was significantly predictive of final course grades and was a stronger predictor of course outcomes than previous academic achievement. However, time spent reading, one of the variables that make up the engagement index was more strongly predictive of course grades than the entire engagement index.
The effects of course level and instructor were controlled as well as the effects of gender, race/ethnicity, and previous academic achievement. In other words, data collected unobtrusively through the use of digital textbooks can be used to predict student outcomes even when using it for courses with different levels of reading, with textbooks that require varying levels of reading comprehension, with instructors who have different teaching styles, and for subject areas that vary in their technical nature.
Other Findings: Interestingly enough, students did not read a great deal with a median reading time of only 169 minutes over the course of a 16-week semester.
Also, students who were in the top 10th percentile in number of highlights had significantly higher course grades than those in the lower 90th percentile. This along with previous research on highlighting behaviors suggests that highlighting might be used as a proxy for level of reading comprehension.
Conclusion: Students who read more, do better in their courses. While that might be a “no duh” kind of conclusion, what is noteworthy from this research is the knowledge that behavioral academic data collected unobtrusively can predict how well a student will do in a course better than previous academic performance (which is typically the single best predictor of course outcomes).
Commonly, students are categorized as “at risk” based on previous academic performance (using high school GPA or SAT scores, for instance); however, this method of focusing interventions casts an overly broad net and misses students who might be struggling for other reasons. Prediction based on digital textbook analytics can help identify students at risk of poor performance in real time, even before a student submits any gradable material to the faculty member. In the future, digital textbook data can be added to other data sources (like learning analytics from learning and course management systems) in order to provide even more precise prediction of student success and to be better able to target interventions for those students most at need.
My newest paper, ￼Student class standing, Facebook use, and academic performance was just published in the Journal of Applied Developmental Psychology.
In previous work, I’ve discovered that social media use is related to a host of academic and psychosocial outcomes. Most notably, there is a relationship between Facebook use and academic performance and Facebook use and student engagement. When looking at time spent on the site, there is a negative relationship between Facebook use and outcome variables; however, when we parse out different ways of using Facebook, then the relationships become more complex. For instance, what students do on Facebook is more positively predictive of academic and engagement outcomes. My previous research has suggested that using Facebook in certain ways might be driving the negative relationship seen between time spent on Facebook and academic performance. Most notably, using Facebook during class or while studying seemed to explain these negative relationships.
In the current study, I surveyed over 1,600 college students and examined the time they spent on Facebook by splitting that time into two categories: 1) Time spent multitasking (i.e., task switching) with Facebook while studying and 2) “Regular” time spent on Facebook. Based on previous research, my hypothesis was that multitasking would drive the negative relationships seen between Facebook use and grades but that “regular” Facebook use would not. I also examined students at different class ranks (freshmen, sophomores, juniors, and seniors) to see if there were any differences that might be attributed to academic maturation.
Here are a few highlights of my findings:
- Seniors spent less time on Facebook than students at other class ranks
- Seniors also spent less time multitasking with Facebook than students at other class ranks
- Regular time spent on Facebook (not multitasking) was negatively related to actual GPA for freshmen but not for students at other class ranks
- Time spent on Facebook multitasking was negatively related to actual GPA for students at all class ranks except for seniors
What does it all mean?
Freshmen need to feel socially integrated into their college or university, for if they don’t, they’re at risk of dropping out. One of the ways that freshmen maintain a connection to previous friends and reach out, engage with, and learn about new friends is through Facebook. Therefore, Facebook plays an important role in helping freshmen adjust to college. However, the ways in which Facebook use are negatively related to grades suggests that freshmen have difficulty regulating their Facebook use in the service of academics. I hypothesize that this isn’t an issue related to Facebook per se, but the relationship between Facebook and grades provides a way of capturing self-regulation skills in freshmen. In other words, the pattern of Facebook use helps us see something about self-regulation we might not otherwise be able to measure. This is also evidenced by how regular use of Facebook for students at other class ranks is not related to academic performance.
Another interesting finding was that seniors did not exhibit a negative relationship between multitasking with Facebook and grades. While this is unexpected given the cognitive science literature on task switching, there have been other studies (including some of my own) that have found that use of certain technologies and use of them in specific ways while engaged in learning tasks do not impact outcomes. This area is ripe for further research and I expect to see more in the coming years elucidating what characteristics of social technologies and of their uses mitigates task-switching detriments in cognitive outcomes.

I’m looking for Ph.D. students who want to come work with me at Iowa State. If you are interested in social technologies and how they impact youth, please apply! This would be a funded position and you would work in my emerging research group that will be composed of Ph.D. and Masters students (and eventually advanced undergraduate students). I’m looking for students who are passionate about this research area. The ideal student will be creative in thinking about new research studies they could (eventually) run themselves and/or in thinking about how my existing data can be analyzed. Bonus points for coding and/or statistics skills.
I’ve got a number of projects going right now:
1. Apps and Educational Success. This is a grant-funded project being conducted in collaboration with my colleagues at University of Michigan. We are evaluating a number of apps designed to help middle and high schoolers get to college as well as apps developed to support students already in college.
2. Big Data/Predictive Analytics. This is a large-scale project where over 400 students allowed me to monitor everything they did on their computers for a month. I also have personality data on the students, survey data, as well as institutional data. One of the goals is to discover predictive models that can help identify students at risk by only using trace data.
3. A project on online safety that’s currently in the works.
4. A project on digital technologies to improve self-regulation skills that’s also currently in the works.
