“I think this is all intriguing, given the rising interest in MOOCs (Massive Open Online Courses). Groups such as Coursera and Udacity are trying to revolutionize higher education, but this study at least suggests that the manner of delivery is not the only element that contributes to learning. “

Several months ago, Clark Quinn and I were at a workshop and we were discussing the problem of evidence-based practice. We agreed that staying connected with academic research was a critical activity for instructional designers, but we both recognized that it was really hard to do. Busy practitioners just don’t have time to sit down and read all the way through the latest copy of BJET (the British Journal of Educational Technology).

The Internet is a mixed blessing in this regard—a huge number of journal articles are freely available online, but the academic publishers are firewalling them more frequently these days. And even if you can get access to articles—who has time to read them?

This Learning Solutions article is the first in a series intended to address this problem. This series will present short summaries of academic research that may be of interest to eLearning designers. The Learning Solutions article authors (there are several of us) will offer a short, blog-length summary of each study and include a brief discussion of the implications for design. Some of the journal articles we summarize will be newly released research, and some will be older studies that we think still have implications for eLearning design.

We are very interested in your feedback—we want to know whether this is helpful to you as a practitioner? Let us know what you think—please leave your reactions in the comments following the article!

The study

Okita, S. Y., Bailenson, J., & Schwartz, D. L. (2007). The mere belief of social interaction improves learning Pilot Study. In D. S. McNamara, & J. G. Trafton (Eds.), Proceedings of the 29th Meeting of the Cognitive Science Society (pp. 1355-1360). Nashville, TN.

The question

Do you learn more if you interact with a live person, or if you interact with a computer? Specifically, does the belief that you are interacting with another person (as opposed to a computer) affect learning?

The study used virtual reality to test this idea. Thirty-five test subjects interacted with a virtual character in a virtual reality environment. All of the participants interacted with the exact same character—the interactions were scripted, and were identical, but part of the test subjects thought that there was a real person operating the virtual character (an avatar) and the other group of test subjects believed they were interacting with a computer-generated character (an agent).

The methods

They randomly assigned two different conditions to 35 college students and then they asked each of the participants to read a one-page text passage that described how a fever works in the body of a sick person. After being told they would have to tutor someone else on the content, they met a young woman named Alyssa and were given a few minutes to get to know her (by playing the game Operation, of all things).

Then they told half of the participants that they were going to interact with Alyssa in a virtual reality environment, while they told the other half they were going to interact with a computer in a virtual reality environment.

They gave the test participants a list of questions to ask the computer-generated character. For example, in the avatar condition, participants thought they were addressing the question to the person they’d met (e.g., “Alyssa, why do your hands and feet get cold when you have a fever?”), and in the agent condition, participants would address the computer (e.g., “Computer, why do your hands and feet get cold when you have a fever?”).

In reality, both conditions were identical. All of the participants interacted with a recorded computer program.

The results

Each of the participants took a post-test to see how much material they retained from the fever passage.  Additionally, the researchers looked at how the participants physically reacted during the experiment using skin conductance level (SCL), which indexes arousal. They used this measure to see how much of a reaction the participants were having to the situation.

Overall, participants who believed they were interacting with a live person (the Avatar condition) did better on the post-test. Their answers were evaluated on a 0-2 scale (0: incorrect or no answer, 1: partially correct but incomplete, 2: precise and detailed).

Researchers also used various tones for the responses. Some of the computer responses sounded exhilarated, some were neutral in tone, and some sounded shameful. (Figure 1)

 

Figure 1: The effects of tone and novelty on performance.

Participants did best when they heard a novel tone from the avatar—for example when they heard an exhilarated response for the first time, or when they heard a shameful response for the first time. Participants who heard the different tones from the computer didn’t show a significant reaction, either in their physical response or in their test results.

Implications for eLearning design

First—people seem to pay more attention if they think they are interacting with a real person. We spend a lot of time trying to get our learners engaged with the material. One of the tools in our toolbox should be social interaction. The increasing availability of social-learning tools makes this more and more viable as a strategy.

Second—part of our role may be to help learners pay attention. We all have an incredible number of stimuli competing for our attention. Nothing was different between the two conditions here except that the avatar group seemed to be paying more attention. Maybe one of our responsibilities as learning designers is to help our learners pay attention. Novelty (in the form of a change in tone or media) and social interaction can potentially help us do that.

I think this is all intriguing given the rising interest in MOOCs (Massive Open Online Courses). Groups such as Coursera and Udacity are trying to revolutionize higher education, but this study at least suggests that the manner of delivery is not the only element that contributes to learning. MOOC designers are working on ways to provide social interaction for learners, but I know that one of the things I get when I pay tuition for a course with a live instructor is the obligation to meet the instructor’s expectations. Just as many people find that personal trainers help them be more disciplined about working out, I use the expectations of a professor to help me maintain discipline around reading and studying a topic.

Julie, good thinking, this series. Is your target only new research findings or do you foresee covering some goldie oldies, too?

Only yesterday I found myself battling the learning styles claptrap with the magnificent meta-study that drove the nails in that one's coffin.
Nice, Julie - I think we'd talked before about the value of something like this; glad you've got things rolling.

There are some interesting points raised in the article you discuss here - particularly related to motivation and attention; this might have me digging a bit deeper into this topic as it would be interesting to see if the results of this sort of study would vary significantly depending on the level of learner expertise.
This is a terrific idea! YES -- practitioners not only need help sifting through individual research studies, but also (and perhaps more) making sense of multiple research studies. To my mind, it's dangerous to assume that the results of one study reveal WHAT WORKS and WHAT WE SHOULD DO. For that, I look for a body of research that I can generalize from, not just a single study. The results should be replicated before we follow their recommendations.

I recently attended a webinar by Dr. Will Thalheimer sponsored by the eLearning Guild titled "Research-Based Learning: 15 Years of Balancing Research and Practice" (in which he mentioned your book, Julie). Will made exactly this point about the need for translators and synthesizers of research. He writes research-to-practice reports containing translation and synthesis of research that are understandable to practitioners and readily applicable. You can find his articles at http://www.work-learning.com.
Love this Julie... VERY interesting! Especially about our role in helping learners pay attention.

For those of you interested in translation of research, don't forget Guild Research. Right now there are Research Reports out that discuss the research on Informal Learning and Social Learning.
Excellent idea, hits the spot! Concur with jaycross, some golden oldies would be useful for those newer to the area
Great resource, I will be looking forward to reading more of these. I started doing something similar about 4 years ago on the more general topic of performance improvement (scanning 30+ journals and surveying 15+ researchers each year for important articles). I have collected lots of articles and given several presentations on what I am finding. A recent presentation for the Michigan ISPI chapter is available at (www.ryanrwatkins.com/presentations.html) with brief summaries of 17 research articles. My favorites from each year are also posted on (www.needsassessment.org) in the Research area -- but the list of exciting research findings could be endless! Enjoy.
This series is an exellent idea!
About this research: I think the impact of the factor person/computer will vary a lot with the relevance of the subject to the learner. Was "fever" of specific relevance for the learners?
Julie, I have been looking for a better way to stay in touch with academic research as an instructional designer. Thank you to all of authors for starting this series. It's very helpful to me! Any research article in e-Learning that you detail will be very informative to me! Thanks again!
This will definitely be a great time-saving resource! In addition, some of us may even be able to share similar experiences which may validate the findings to a certain extent.
To Jaycross, what is the study you refer to by the comment 'Only yesterday I found myself battling the learning styles claptrap with the magnificent meta-study that drove the nails in that one's coffin.'?
