The problem

As the authors state in the article (O’Connor et al., 2018):

From a modeling perspective, the nanoscale represents an interesting domain, because the objects of study (for example, molecules) are invisible to the naked eye, and their behavior is governed by physical forces and interactions significantly different from those forces and interactions that we encounter during our day-to-day phenomenological experience. In domains like this, which are imperceptible to the naked eye, effective models are vital to provide the insight required to make research progress….

molecular systems typically have thousands of degrees of freedom. As a result, their motion is characterized by a complicated, highly correlated, and elegant many-body dynamical choreography, which is nonintuitive compared to the more familiar mechanics of objects that we encounter in the everyday physical world. Their combined complexity, unfamiliarity, and importance make molecules particularly interesting candidates for investigating the potential of new digital modeling paradigms.

Until recently, building dynamic models that operate not only in real time but also in three dimensions required not only specialized virtual reality equipment, but more importantly massive amounts of computing power to handle the visual representation and modelling of highly complex and dynamic molecular activity.

The solution

However, through the use of cloud computing and faster networks, building such models has now become a reality, enabling not only such models to be represented but allowing some degree of real-time manipulation by researchers in different locations but within the same time-frame – in other words, distance research and teaching. 

In the Department of Chemistry at the University of Bristol in the U.K., Dr. David Glowacki and his team in their VR laboratory have created an interactive molecular dynamics modelling tool in the form of Nano Simbox VR, which allows anyone to visit and play within the invisible molecular world. This was made possible through a partnership with Oracle which provided the researchers access to its Oracle Cloud Infrastructure with a grant from the Oracle Startup for Higher Education programme.

The main advantage of the use of a cloud platform is to allow the scaling up of modelling from simple to much more complex dynamic nano interactions and the synchronous sharing of the virtual reality experience with multiple users.

The Nano Simbox VR app allows several people to interact at once with the digital models. Users can download the framework and choose the Oracle data center (Frankfurt, Germany; Phoenix, Arizona; Ashburn, Virginia) nearest to them for minimal network latency. 

The main aim of this particular project is to provide an intuitive feeling of the way molecules operate in multiple dimensions to enable researchers and students to have a better understanding of how nano worlds operate.

The paper published by Glowacki and his team in Science Advances describes how the iMD VR app enabled researchers to

  • easily “grab” individual C60 atoms and manipulate their real-time dynamics to pass the C60 back and forth between each other.
  • take hold of a fully solvated benzylpenicillin ligand and interactively guide it to dock it within the active site of the TEM-1 β-lactamase enzyme (with both molecules fully flexible and dynamic) and generate the correct binding mode (33), a process that is important to understanding antimicrobial resistance
  • guide a methane molecule (CH4) through a carbon nanotube, changing the screw sense of an organic helicene molecule,
  • tie a knot in a small polypeptide [17-alanine (17-ALA)].

Glowacki’s team measured how quickly users were able to accomplish these tasks using the iMD VR app compared with other platforms, and found that in all applications the VR application led to faster mastery.


This is just one instance where VR is operating at the interface of research and teaching. In particular, its value lies in providing a deep, intuitive understanding of phenomena that are otherwise difficult if not impossible to visualise in other ways.

In some ways this reminds me of the impact of the first mathematics television programs developed by the UK Open University in the 1970s, which included simulations and models of mathematical formulae and processes. This enabled students who were often struggling with the abstract nature of numerical and algebraic calculations to understand in more concrete terms what the calculations and formulae meant.

This intuitive understanding is critical not only for deeper understanding but also for breakthroughs in research and applications of science. In other words, it is a great use of media in education.

The current madness in online learning: case no. 2

Keith Devlin, Stanford University, who offers a MOOC on mathematical thinking. Is there a bias of white male presenters in MOOCs?

Baker, R. et al. (2018) Bias in Online Classes: Evidence from a Field Experiment, Stanford CA: Stanford Center for Education Policy Analysis, CEPA Working Paper  No. 18-03

Yesterday I ranted at the high costs in the UK of online programs aimed at part-time, working people. Today, I want to look at a recent study from researchers at Stanford University reporting racial bias in online discussion forums.

First let’s report the facts: what did the researchers say? (Please read the report for yourself if you are uncomfortable with my comments about their conclusions).

Main finding

They report:

this study provides what we believe is the first evidence of the possible presence of racial and gender biases among students and instructors in online courses. 

First, it provides novel and fundamentally important insights into a rapidly proliferating type of learning environment. In 2013, 25 percent of all postsecondary students took some or all of their courses online. This fact has equity implications given that students enrolling in less selective colleges make up a larger fraction of the online student body online. Even in K-12 education, more than 300,000 students exclusively attend online schools, with as many as 5 million students having taken at least one online course….

Because our study relies on fictive student identities, it cleanly isolates behavioral effects due to instructors and unequivocally rules out mechanisms related to student reactions to a particular instructor.

…a comment from a White male is a statistically significant 5.8 percentage points more likely to receive a response from an instructor than non-White male students. The magnitude of this effect is striking. Given the instructor reply rate of 6.2 percent for non-White male posters, the White male effect represents an 94 percent increase in the likelihood of instructor response.

This is a pretty damning criticism of online learning. How did they come to this conclusion?


We tested for the presence of racial and gender biases in these settings by creating fictional student identities with racial- and gender-connotative names, having these fictional students place randomly assigned comments in the discussion forums, and observing the engagement of other students and instructors with these comments.

We situated our study within 124 Massive Open Online Courses…..Critically, we also believe there is credible external validity to conducting this study within MOOCs because their basic design features (e.g., asynchronous engagement, recorded lectures, discussion forums) and their postsecondary content are widely used in other online courses.

Using fictive student identities, we placed eight discussion-forum comments in each of the 124 MOOCs. Within each course, eight student accounts were used to place one comment each. The eight student accounts each had a name that was connotative of a specific race and gender (i.e., White, Black, Indian, Chinese, each by gender); each race-gender combination was used once per class…..By observing the responses to our comments by instructors and by students in the course, we can identify any difference in the number of responses received by our student accounts that were assigned different race and gender identities.

Fifty eight percent of the courses in our sample were taught by either one White male instructor or a teaching team of exclusively White men….White students were 5.9 percentage points more likely than non-White students to respond to one of our comments when that comment was assigned a White name….We find that White women were over 10 percentage points more likely to respond to a post with a White female name than non-White women.

My comments

This study has received a lot of attention, being reported in many different outlets. The main reporting suggests that discussions in online learning are strongly biased, with more attention being paid to white male students by instructors, and white female students more likely to correspond with or respond to other white females.

I don’t dispute these findings, as far as they apply to the 124 MOOCs that the researchers studied.

Where the madness comes in is then generalising this to all online courses. This is like finding that members of drug gangs in Mexico are likely to kill each other so the probability of death by gunfire is the same for all Mexicans.

MOOCs are one specific type of online learning, offered mainly by elitist institutions with predominantly white male faculty delivering the MOOCs.

Furthermore, the instructor:student ratio in MOOCs is far higher than in credit-based online learning, which still remains the main form of online learning, despite the nonsense spouted by Stanford, MIT and Harvard about MOOCs. In an edX or Coursera MOOC, with very many students, it is impossible for an instructor to respond to every student. Some form of selection has to take place.

In most credit-based online courses, discussion forums are much more tightly managed by instructors. Many using best practices try to ensure that all students in their online discussion forum are as fully engaged as possible in the discussions. This is just not possible for an instructor to ensure in very large MOOC discussions forums. Also to imply that their findings will also apply to k-12 online courses is even more ridiculous. Their statement that the basic design features of MOOCs are widely used in other online courses is just not correct.

So yes, because of the very nature of most MOOCs, I am not surprised to find racial and gender bias in the discussions forums. I am sure that if one looked closely enough, one would probably find some instructors in credit-based online courses show either conscious or unconscious bias, but I would need to see evidence drawn from this context, not from a completely different context such as MOOCs.

Once again, we see faculty from Stanford assuming that MOOCs are the standard for online learning, when all along they have been a mutant, and so it is not surprising to find mutant behaviour in them.

What I would like to see in online learning in 2018: 1: a theory of classroom affordances

Prediction is difficult, especially about the future, so I won’t waste your time in suggesting what technologies are likely to take off in 2018. Instead, I’d rather focus on what I would like to see happen in 2018.

A research-based theory of classroom affordances

a. The challenge

With more and more teaching and learning occurring online, every instructor is now faced with the question: what is best done face-to-face and what is best done online? From a student’s point of view, what can the institution offer educationally on campus that they cannot get online? I am suggesting that we do not yet have a sufficiently powerful research-based theory that can realistically answer these questions.

b. What we know

Those of us working in online learning are well aware of the assumption made by many instructors that the classroom experience is inherently superior to any form of online learning. We are also aware of how often this assumption has proved wrong, with for instance student-student and student-instructor interactions online often being just as or more effective than in classrooms.

With the development of video, simulations, games-based learning and remote labs, even forms of experiential learning such as scientific and engineering experiments, manual operations and familiarity with tools can be developed as effectively online as in labs, workshops or classrooms. 

However, the differences between the effectiveness of online learning and face-to-face learning usually are dependent as much on the context or the circumstances of learning as on inherent qualities of what is to be taught or the medium of teaching. It is clear there are some circumstances where we now know online learning is preferable to face-to-face teaching (e.g. where learners have difficulty accessing physical classrooms, either because they are working or because it means a two hour commute) and where face-to-face teaching is more practical than online learning (e.g. where students need to handle and use heavy equipment). 

c. The need for a theory – and research questions

Nevertheless, there are other circumstances where either it doesn’t matter in terms of learning effectiveness whether it is done face-to-face or online, or where indeed there are significant differences in certain circumstances, but we don’t yet know what these are because we have not tested or challenged them.

So we need research-based evidence that can answer the following research question:

Under what conditions and for what purposes is it better to learn in a face-to-face context rather than online? And when and how should they be used to complement each other when both are readily available?

Can we produce a theory from such evidence that would enable a set of rules or criteria that instructors could use to make such a decision? What research would be needed to develop or test such a theory?

d. Is there no current theory we could use or build on?

There are plenty of theories of how learning best takes place¹, plenty of theories that are used to support best practices in face-to-face teaching², and similarly a few theories that suggest best practices in online learning and teaching³. What we don’t have is theory about the differences (if any) between face-to-face and online learning in specific circumstances or conditions, backed by reliable research evidence, when both are available in practice.

One potentially promising line of enquiry could be built around the research on the pedagogical affordances of different media: what kinds of learning can specific media support or help develop? If we treat face-to-face teaching as a medium, what are its pedagogical affordances: what can it do better than other media? (see Norman, 1988 and Chapter 7 of Teaching in a Digital Age)

However, the issue in deciding what to do online or face-to-face is usually not only pedagogical but as much to do with cost, instructor convenience, and a lack of imagination of how things could be done differently. Also the context is critically important. An effective theory will need to incorporate all these factors.

Note that most research on differences between online learning and face-to-face teaching at a meta level results in no significant differences overall. The factors or conditions that lead to differences often cancel each other out and are ‘controlled’ or eliminated from the studies to ensure ‘comparability.’ Thus – surprise, surprise – good quality online learning could be better than poor quality face-to-face teaching, and vice versa. Thus the conditions in which each is used is essential for evaluating their effectiveness. Furthermore these meta studies are looking at replacing face-to-face teaching with online learning or more recently blended learning, not at what the unique teaching characteristics of each mode may be, and in what conditions.

However it is precisely these ‘conditions’ that we should be researching to answer the research questions outlined above. When does online learning work better than face-to-face teaching and vice-versa? In other words, do not assume that it does not matter whether we teach online or face-to-face because the research shows no statistical differences, but instead let’s focus on identifying those specific conditions that actually do lead to significant differences, especially when both are equally available to instructors and students.

e. What about the SECTIONS model?

The SECTIONS model I have proposed in my open, online textbook, Teaching in a Digital Age, provides a set of questions that instructors should ask before finalising decisions on the choice of a particular medium or technology for teaching, partly based on their pedagogical affordances (T for Teaching and I for Interaction) but also on other factors such as student access, costs, and security. If we think of face-to-face teaching as just another teaching medium, could not the SECTIONS model be applied to answering the research questions in 1. c above? 

This could be one starting point perhaps for such a theory, but it will need much more research to test and validate it. In Chapter 7, I looked at all media except face-to-face teaching, because I was unaware of relevant research that could identify the unique features of face-to-face teaching when online learning could also be used.

Furthermore, face-to-face teaching is not monolithic, but can vary enormously – as can other media – and also can incorporate other media, so probably more research is needed to establish the conditions where face-to-face teaching is superior. 

f. What about Teaching in a Digital Age?

If you have read my online open textbook, you might think that this provides a theoretical basis for choosing between face-to-face and online learning. Certainly it does discuss a number of different educational theories and looks at several different teaching methods. It also suggests guidelines based on research and best practices for choosing between different modes of delivery and different media (except face-to-face teaching as a medium).

But the book is not written as a particular theory of teaching and does not provide enough theory to identify what to do regarding the ‘either online or face-to-face when I can use both’ decision within a specific teaching context. It is more a set of guidelines derived from existing theory and best practice. Someone else needs to move this work further.

g. Next steps

  1. Acknowledge and have recognized the significance of the research questions. This is an extremely important issue for research in education. We know from the National Survey of Online and Distance Learning in Canadian Post-secondary Education that the move to blended and hybrid learning is growing rapidly. Every instructor will soon face the question of what should be done in class and what online, but we have few answers at the moment that go beyond beliefs or prejudice;
  2. build these research questions into doctoral programs in education, so we have a growing body of evidence on the research questions and students and supervisors thinking about the issue and developing hypotheses and research evidence to support them;
  3. develop a national program of research into this issue so that there is a significant mass of study and research that will likely lead to some practical and useful answers in different subject domains.

I should make it clear I have no intention or wish to lead this research because I am trying to reduce my work commitments as I grow older. It is my privilege to pose such questions but not my responsibility to answer them! I just hope though someone else will pick up the gauntlet I have thrown down.

Over to you

This is meant as a ‘thought piece’ to stimulate thinking around a particular issue that I think is important. However, you may have different views on this that I hope you will share, in particular:

  1. Is this really an important issue? Do we really need research on this? Why not let instructors experiment and find out what works best for them without the need for any formal research?
  2. Is the question: ‘What should be done online and what face-to-face under what conditions?’ a question suitable for research? Are there other, better questions that should be asked?
  3. What existing theories could help with this question? Do we need yet another theory – or just a few more hypotheses that can be tested within existing theoretical frameworks? If so which one(s)?

Are you ready for blended learning?


I’ve just come back from visiting two universities in central Canada and I have also been getting feedback from pilot institutions on the questionnaire we are developing for a survey of online learning in Canada. Although I do not want to anticipate the results of the survey, some things are already becoming clear, especially about blended learning.


First of course there is the question of definition. What actually is blended learning? It clearly means different things to different people. I have tried to describe it as on a continuum of educational delivery (see graphic below):

From Chapter 9.1.2, Teaching in a Digital Age

From Chapter 9.1.2, Teaching in a Digital Age

Blended learning can be seen as

  • nothing more than Powerpoint slides in a classroom lecture,
  • extra homework online after a face-to-face class,
  • a ‘flipped’ classroom where the lecture is recorded and available online, and the class time is used for discussion and questions about the video
  • a totally re-designed course, where careful choices have been made about what is done online and what in class (hybrid).

When there are so many different meanings for the same phrase, it becomes somewhat meaningless. For this reason, one recommendation made to us most strongly was that in our survey blended should be counted only when there is a deliberate replacement of face-to-face time with online learning. At least that should be measurable. But what if, in a flipped class, the lecture time is merely replaced with a face-to-face seminar, with the lecture online? Same amount of face-to-face teaching but an increased workload for the student.

It’s not about quantity; it’s about quality

If we take the broad definition to include all or most of the points above, we can certainly make one fairly confident prediction. Nearly all post-secondary teaching, at least in North America, will be blended. In other words, almost all teaching will be either fully online, or a mix of classroom and online activities, if it is not already. Even in the most traditional lecture-based physics courses, for instance, students are likely to have online exercises to do associated with the course set book.

In fact we’ve been told in some of the feedback on the survey questionnaire that blended learning is already the norm in most Canadian post-secondary institutions. This may or may not be true – hopefully the survey will reject or confirm this assumption – but that seems to be the perception of many of those closest to the action. The issue then is not will blended learning become the norm, but how quickly, and my guess is that nearly all courses in Canadian post-secondary institutions will be online or blended within the next five years.

The key question then is not whether or not blended learning will be the norm, but will it be done well or badly? It is this question that keeps me awake at night, because there is no guarantee that classroom instructors drifting into blended learning know anything about the best practices for online teaching, or indeed whether these best practices will migrate successfully to the many different forms of blended learning that will emerge.

What do we do on campus when students can learn most things online?

One reason I lie awake at night is because we have no evidence-based research or theory that can guide instructors on this question. We certainly have a lot of opinions about what can best be taught online and what face-to-face, and we certainly have a lot of good research and theory, and best practice, about how to teach effectively fully online.

Indeed, it is the on-campus activities that are less well defined when students can study online. Or to put it more bluntly, what can we offer students on campus that makes it worth their time to get out of bed and on the bus on a cold and frosty morning that they can’t get by staying home and studying online? What is the added value of the campus or the classroom?

The answer to this question of course will vary from subject to subject. An experienced instructor will maybe intuitively work this out for herself, but there is a lot of scope for getting it wrong as well. I don’t want to under-rate instructor intuition, but theory and research on this question is desperately needed, at least to offset guessing and ‘I know best’ attitudes. Indeed, for far too long, many on-campus instructors have incorrectly assumed that certain teaching or learning activities can only be done well on campus when in fact we have found they can be done just as well or better online. In the future, if not at present, even laboratory work may be done as well online through the use of remote labs, online simulations and/or augmented reality.

So what guidelines or framework can we offer instructors in making these decisions? I have suggested in Chapter 9 of Teaching in a Digital Age four criteria and a simple process for making a decision about the mode of delivery but I am more aware than anybody how fragile and tentative this is without it being backed by theory and research. It is also one thing to decide to do a blended class rather than a face-to-face class, but quite another to decide what should best be done in each of the different modes of delivery.

Why get on the bus when you can study online?

Why get on the bus when you can study online?

Organizational issues

Another factor which unfortunately is often the first issue that institutions try to determine when moving to blended learning is the organizational structure for the learning support units, such as those housing instructional designers, web and media developers, and technical support for LMSs, etc. For many institutions, it is recognized that mainline, on-campus faculty will need substantial learning technology and instructional design support if they are to move to blended learning, but the problem is perceived as having the support in the wrong places.

In many North American universities, this support is often concentrated in Continuing Studies, because, historically, this is the unit that has supported distance and fully online learning. Now that support is needed for on-campus activities. However, the units supporting fully online courses and programs are usually themselves over-stretched, just managing the fully online courses.

Although it is important eventually to align support to where it is most needed, the problem should not be seen as an organizational issue but as a resource issue: there is just not enough existing resources going into academic support to cope with an expansion into blended learning.

The scaling issue

This is the main reason for my lying awake at night. Institutions are already spending a good deal to support just the fully online courses or programs. We have good models here based on instructional designers and media specialists working in a team with instructors in developing fully online courses. This way, the special design requirements for students studying off campus can be met.

However, at the moment, fully online courses constitute somewhere around 10-15% of all the credit-based teaching in North American universities. What happens when we go to 85% or more of the teaching being blended? The current learning technology support model just won’t be able to handle this expansion, certainly not at the rate that it is being predicted. However, without a design strategy for blended learning, and adequate support for faculty and instructors, it is almost certain that the quality will be poor, and it is certain that all the potential benefits of blended learning for transforming the quality of teaching will not be achieved.

Trying to extend the support system from fully online to blended courses and programs will ultimately be unsustainable. Although support units will be essential to get blended learning successfully started, teaching activities must be economically sustainable, which means faculty and instructors will eventually need to become able to design and manage blended learning effectively without continuous and ongoing support from instructional designers and media producers. This will require a huge training and retraining effort for instructors.

Possible solutions

As always, identifying a challenge is much easier than resolving it. But here are some suggestions (please suggest others):

  • Develop an institutional strategy for teaching and learning. Give priority in terms of resources and support to those academic areas ready and wanting to move into innovative teaching, in whatever mode it takes.
  • Identify additional resources for a move to innovative teaching, in the form of extra instructional designers, media producers and release time for faculty for initial course design and development. (This is a good indicator of just how serious the institution is about changing teaching). This will provide a core of support to get things going in an effective manner.
  • Give priority to supporting innovative blended learning designs, where the course is re-designed with a clear rationale for what is being done online and what face-to-face.
  • In particular give priority to supporting academic programs that have a clear strategy for blended and online learning and how it will be delivered across the program
  • Encourage innovation in blended learning design, but ensure that it is properly evaluated and that there is a strategy, if the innovation is successful, for ensuring the design is more widely applied.
  • Don’t mess with successfully operating support units that already exist. If they were needed before for what they do, they are still needed for that. Set up new units to support the move to blended learning and locate them close to the academic departments where they will be needed. Build an institutional community of practice so that the different support units can learn from each other.
  • The most important suggestion of all: overhaul completely your faculty development and training. Start with an online or blended course on how to teach online or in a blended format. Make it mandatory for instructors getting institutional support for blended or online learning. Provide a teaching track for appointments, promotion and tenure to reward innovative teaching. Redesign the post-graduate experience to ensure that teaching methods and pedagogy are also covered as well as research expertise, and ensure a direct link between such courses and teaching appointments. Provide badges, certificates or post-graduate diplomas or degrees for instructors who can demonstrate they have taken courses on teaching in post-secondary education.
  • Give research into blended learning a high priority in the SSHRC; this is going to be the norm and we need to know what works and what doesn’t. In particular we need some good theory on the pedagogical differences between online and classroom teaching – not comparative research about which is best, but what each is uniquely suitable for within a particular subject discipline and teaching context.

Then you will be ready for blended learning.

Over to you

Do you share my concerns or am I just a nervous Nellie? Should we just leave everyone to work it out for themselves?

Alternatively, what do you think needs to be done to ensure that blended learning is introduced sustainably and with high quality?

Does your institution have a plan for dealing with the move to blended learning? Is it a good plan?
