Virtual Reality in a Learning Environment

Introduction

Virtual reality or VR as it is often referred to is one of the latest buzz words in technology, with applications showing up for gaming, design, media, travel, and education.  What is it really though?  VR is a method of visualizing media content, usually through wearable peripherals.  The most common pieces that make up a VR experience include a headset with small screens in front of the eyes, headphones or speakers, and controllers in the users hands.  These pieces come together to simulate a generated environment that the user is in, so that when they turn their head, the image moves in unison on the screen, making it feel like they’re looking around the virtual environment.  It’s a method of

transporting oneself out of the environment they’re currently in into any environment that could be conceived.  It could be a beach, a giant movie theater, a game, etc.  The environment can be artificial (Computer generated), or a video or image that was taken by a 360 degree camera or camera setup.

There are a few terms that are closely associated with VR, but that mean slightly different things, which we’ll briefly go over to remove any ambiguity.  Augmented Reality (AR), is when the user can see the REAL world around them, and images or animations are superimposed on their vision, often through mini projectors onto glasses.  Mixed Reality (MR) is similar and overlaps with both VR and AR, and refers to when artificial objects are overlayed onto the real world.  Whatever the application, “virtual … experiences are not fads soon to fade away” (Johnson, 2019).

Regarding VR in education, “VR has been shown to lead to changes in student attitudes, such as increasing student engagement or self-efficacy” (Cook et al., 2019).  We will be reviewing the use of VR in education, specifically how it can be used, its pros and cons, and how it may improve education.  The following headings are applied based on the SECTIONS model of Teaching in a Digital Age – Second Edition (CC BY-NC).

Students

Student demographics have a significant influence on how a course can be taught.  Some students will have a desire for a face-to-face instructional method that lends them many aids while studying, others will want the flexibility of an online course so it can be taken while working.  The benefit of VR is that it can fulfill both of these requirements.  It can be used to make a course entirely online based, and be accessible from home, but also allows direct contact between the student and teacher in a learning classroom environment.  VR headsets can allow multiple people (students and teacher in this case) to enter a virtual lobby or classroom, where they can look around, interact, and learn.

Ease of use

The ease of use of VR headsets seems to scale inversely with the cost, which for our application is actually quite useful.  The more inexpensive the VR, the easier it is to use, possibly only with the exception of google cardboard (the flimsiness of the cardboard adds to the difficulty).  Ease of use is often a limiting factor for teaching, as any time used to teach how to use the technology will subtract from the time available to teach the actual topic.  The simplest forms of VR are simple and application based, with clear instructions, as well as moderately inexpensive.  Examples of this include Google Cardboard, Google Daydream, and Samsung Gear VR.

Costs

Google Cardboard

This is an area where VR can tend to struggle.  Depending on the technology being used, it can be as simple as putting a mobile device (smartphone) into a headset and following the prompts.  Mobile friendly headsets cost as little as $15. Or as complicated as setting up a plethora of sensors around a room, wiring them all correctly, installing multiple programs on a desktop computer capable of processing the difficult computations associated with VR, etc.  These applications, assuming you have a powerful enough computer already, have costs in the realm of $600.  For educational purposes the simplest and least expensive implementation would probably be sufficient.  Products like google daydream or google cardboard are quite inexpensive, and could accommodate most classroom requirements.  They do however require a compatible smartphone, something that some students may not have.

Brown and Green found that “Much of the truly useful virtual reality production and presentation software is freely available to educators and students” (2016).  Additionally, Unity software, an industry standard, and Google’s Street View project are also both free, and provide excellent educational tools (Brown and Green, 2016).

Teaching functions

When it comes to teaching functions, this is an area where VR has the potential to excel.  Virtual Reality can be used to build a virtual classroom, that when donning headsets each student would then find themselves in.  Teachers could have their faces visible, and a slide deck in view as well, just like a classic classroom.  If they wanted they could move the entire class to almost any outdoor setting or experience, like a planatarium, museum, foreign monument, etc.  The different teaching tools available are almost endless. Students could virtually raise their hands when wanting to ask a question, or move back and forth within the slide deck in case they missed something without bothering others.  For those who aren’t available during regular class hours the entire class could be recorded so they could experience it at their convenience.

In a study carried out by Makransky et al., their research supported the equivalence hypothesis, “that students learn as well from computer-based interactive science simulations when they are performed at home as when they are performed in class” (2019).  This shows that people learn just as well when using a VR platform as when in a classic classroom situation (Makransky et al., 2019).

Interaction

This topic was already touched on briefly in teaching functions.  VR is one of the best environments for digital interaction since it employs not only voice, but also an motion or movement the user wants to make.  Each character in a chat room can have an avatar representing themselves, and sees all other members around them.  They can walk around, talk, interact, separate into groups, etc.  The closer you are to someone the louder conversation can be, so ultimately a large group could develop into smaller in class discussions if necessary, but still not be disconnected from the whole.  The potential for class interaction is quite large.

Organisational issues

This is an area that is less applicable to the area of VR.  Any organisational issues that exist pre-implementation will likely continue to exist, and VR is unlikely to introduce any significant organisational issues of its own.  VR is a tool by which teaching methods can be expanded online, and into an environment that is flexible for a larger number of students.  It incorporates tools that already exist, like exercises, slide  decks, etc, and increases their accessibility.

Networking

This is an area that is still growing in VR.  Due to it being quite a young technology, the infrastructure of social networks has not yet fully developed around it.  There are social networks for VR, but they are still young and in development.  If networking is one of the significant requirements of an online course, then VR may not be the best choice of technologies to implement.

Security and privacy

The security and privacy of using VR in an online environment is similar to that of using any other online technology.  There is a greater than zero risk that information uploaded is not private.  Because of this, any usual privacy measures should be followed.  Users are recommended to take all normal precautions for anonymity on the web.  Don’t use your real name, or give out information like birthdate, etc.  Otherwise, VR isn’t any less secure or private than other online social platforms, and your privacy is ultimately dependent on your own connection, where you’re accessing from, where the chat room is hosted, etc.  Privacy and security are a concern, but not a major one, and not significant compared to other online platforms.  However, finding a service where all server data is stored within Canadian borders could prove to be difficult, especially considering how young the technology is.

Examples and Challenges of VR

An inner-city charter school in Washington D.C. is using virtual reality teaching applications in a variety of ways, including following the story of a “migrant traveling from Guatemala to the Texas border”, sitting in the front row of a Prince concert, and a course module on the Vietnam War (McKibben, 2019).

As novelty goes, VR is a huge success, and is showing signs of maintaining interest even after the novelty factor wears off.  Johnson has found “[s]tudents are motivated to include VR experiences in their learning. For example, of their own volition, social studies learners have chosen to include 360-degree immersive experiences rather than twodimensional illustrations as part of projects. These students have also begun to create 360-degree
content of their own” (Johnson, 2019).

One of the major current setbacks of VR is the lack of standardization.  There aren’t any standart formats for how content is coded, with many different companies using their own formats, and there aren’t any best practices in place either, forcing institutions wanting to adopt VR to come up with their own solutions (Cook et al., 2019).

Conclusion

Virtual Reality is an incredible technology that is still in its early phase, and growing at an alarming rate.  There are still quite a number of unknowns regarding how it could be applied, and where it will go.  We do know how it is being used currently, and that there seems to be incredible potential for applying it to learning, specifically online and at home learning applications.  Despite how new the technology is, it has already reached a level of cost that is within the grasp of teaching tools, as well as a simplicity of use that makes it easily applicable in a teaching setting.  It compliments teaching applications and interaction, and has minimal organisational issues.  It does still have setbacks regarding networking and data privacy, but with time those should also be overcome.  Overall it is an exciting technology which is usable now, and has the potential to take the teaching and educational world by storm within the next decade.

MY SURROUND SOUND ADVENTURE

The majority of my more memorable online learning experiences have been when I’ve become interested in a hobby or topic, and take it upon myself to find as much information as I can.  This has included looking up information about how headphones work, digging into the world of numismatics, exploring the developments of a certain groundbreaking electronic vehicle company, or most recently, my quest to understand home-theater setups, and how to build one from scratch.  I’m a bit of a techy, and have a certain appreciation for AV equipment and good cinema, so when the chance to go from a simple soundbar to a full surround sound system presented itself I jumped at the opportunity!  I’d found some high quality

speakers listed for free pickup because the surrounds had deteriorated, and I was sure I could fix them.  If you’re wondering what a surround is, it’s the foam circle around a speaker cone, and can be seen in the picture to the left.  But now I found myself with speakers, and no way to plug them in, and so I began to do research regarding how to complete a surround sound setup, and discovered a world I had known to be deep and complex, but was much more so than I had imagined.

First Acquisitions

First off, since I had picked up a set of passive speakers (un-powered), I apparently would need an amp or receiver to power

them.  Now an amp simply provides power, while a receiver is the intermediary of a home theater setup, having IO for all audio and visuals.  I needed the latter.  But a receiver can be very confusing to look at, and there are many different types, prices, and features.  With speaker setups there are a variety of formats, each of which has their pros and cons: 2.0, 5.1, 7.1, Dolby Atmos.  I researched the different forms and settled on 5.1 as the format that would work the best with my space, desires, and budget.  I then had to find a receiver that would work, and be powerful enough to drive my speakers, add additional speakers, since a 5.1 system requires 6 speakers, and figure out the best way to put it all together.

How I found Information

For my research I used a variety of tools.  I looked up

tutorial videos and

informational videos on YouTube, I looked up answers to specific questions on Reddit, as well as a variety of opinion pieces, debates, and other fun stuff.  I found specifications and reviews for specific devices and products on retailer websites like Bestbuy and Amazon as well.  I find video to be an excellent medium for myself.  I’ll often watch them as breaks from tasks (like homework), or while working

on menial chores (dishes, vacuuming).  They allow me to disconnect from my task, and enjoy hearing about how someone else is passionate about a certain topic.  In recent research regarding the uptake of YouTube based clinical digital education, Rangarajan has found an increase in the number of users going to YouTube for information, and comments on the efficacy of said platform (Rangarajan, 2019).

Reddit is a medium that offers humanization of the learning experience for me.  It’s a discussion of a variety of people, some more informed than others, and some more opinionated.  It allows everyone to be on an equal standing, and give their opinion on a topic, and lends a transparency to what you’re learning.  You see past the facts and figures to the real life scenarios, the ways things can go wrong, and so on.  YouTube is able to offer this as well, but to a lesser extent, as it is often more edited and what you see is more controlled.

Wrapping It Up

Through watching informational videos and reading guides I found out how power levels on speakers are rated, and how to read them.  I informed myself on different types of speakers (powered, passive, floor-standing, satellite, bookshelf), how the quality of cables might effect sound.  How to plugin, setup, and calibrate the various pieces of equipment, and familiarized myself with the various brands and types available.  Below are a few different sets of surround speakers, as well as a diagram of a typical 5.1 setup.

This type of learning is fun for me, and I find picking up little hobbies can be quite rewarding.  Despite none of the resources I used costing any money, I still was able to come away quite informed.  However, due to many varying opinions, I did have to apply a level of discernment regarding contrary information or opinions.  I know this learning method is not ideal for many, however I believe it’s an excellent way to acquire new knowledge and apply it at the same time.

Fourth Reflection

The Floe Inclusive Learning Design Handbook (Attribution 2.5 Canada (CC BY 2.5 CA)) is an excellent learning tool for designing and improving educational resources.  It has been created for teachers, and content creators in general as a free resource for increasing their ability to teach by improving the resources they have.  It has a strong focus on inclusivity and adapting resources for people coming from a wide spectrum of situations.

“handbook Co Pocket” by lexly87 aka Duc N. Ly is licensed under CC BY-SA 2.0

Within the handbook, the three concepts that seemed the most important to me were the three dimensions of inclusive design.  These are the foundation for creating a design that is accessible and usable by the widest spectrum of people possible.

Here are the three dimensions:

  1. Recognize, respect, and design for human uniqueness and variability.
  2. Use inclusive, open & transparent processes, and co-design with people who have a diversity of perspectives, including people that can’t use or have difficulty using the current designs.
  3. Realize that you are designing in a complex adaptive system.

The first identifies the fact that not all people are the same, but all deserve recognition and respect.  If you start off creating material without this concept in mind, then you’ve already failed.  The second one speaks to principles that will help with designing effective tools.  Again, it includes as many people as possible in the process, because many people learn in different ways, so it wants to allow for as many learning styles as possible.  The third simply speaks to the fact that once the tool is designed, the journey is not over.  The content may change, or the audience, or the means by which to communicate the information.  Things are always changing, and we need to be prepared for that, and accept that our design will probably have to change over time as well.

There were a couple ideas within the material that didn’t completely understand or agree with.

The first was the section within perspectives with the heading: “If you are unique (and aren’t we all), numbers are not our friends“.  Which spoke about how the size of numbers is a constant pursuit for humans, and in a world where the biggest number gives value, when you’re only a small number (minimal readers, likes or view count), it can be discouraging.  However, I think numbers can give us very valuable information, and if you can learn to remove your worth from the numbers, then joy can be derived from seeing numbers increase, or feedback about what to change when numbers decrease.  Numbers be a great source of information, and when properly applied, are indeed our friends.  They aren’t malevolent, we just need to view them properly, and not attach our value to them.

The second was “Sonification“.  I found the topic interesting, but hard to think of applications where it would be well used, or make a significant difference in the learning experience.  Using non-verbal audio is not overcoming a major accessibility barrier, and using sounds allows rudimentary communication, but can’t communicate any more without visual aids.  Ultimately I see it as having minimal usefulness.

The one question I found unanswered was simply where are examples pertaining to all these techniques and theories?  It would be nice to see more examples of the methodologies and techniques in action, as well as more evidence for why one method is better than others.

Second Reflection

Historically, educational content has always come at a premium.  Education was a luxury that only the rich could afford, whether it was private schools, tutoring, or lessons.  More recently primary education was considered a human right, at least in most developed countries, and is offered to our children for free, even required.  However, higher degrees of education, in Canada, are still extremely expensive, causing many who still desire an education to take on large amounts of debt.  Some of these educational resources are available online, at a cost.   Openly licensed educational content has a different pursuit however.  The goal is to make educational content available to the public free of charge.  The main difference then is that online educational content either has a cost associated to it, or its access and use is limited.  However, openly licensed educational content is free to use, and often can even be replicated, and modified to create additional teaching resources.

An example of such an educational resource is Kimball’s Biology Pages, which can be found at the following url: https://www.oercommons.org/courses/kimball-s-biology-pages

It is a freely available resource created by John W. Kimball.  It’s a biology textbook, formatted in HTML to be viewed and easily navigated through a standard web browser.  It covers a variety of topics, and is kept up to date regarding changes in the world of biology as well.  It’s an excellent resource for anyone interested in the topic, but unable to afford a $200 textbook.

Relevance: The information would address class objectives relating to biology.

Accuracy: The information is accurate, with no obvious content errors or omissions.  No obvious spelling errors or typos.  It is unclear whether the material has been peer reviewed.

Production Quality: The information is clear and understandable, the interface is simple, but not completely user friendly.  Due to the simple html it is not as easy to understand the layout as it could be.  The design features do not strongly enhance learning.  It is not a multimedia resource.

Accessibility: The resource does not seem to be available in alternate formats.

Interactivity: The resource does not encourage active learning or class participation.  However, it could be adapted to do so, since the license allows modifications.  There appear to be no embedded questions.

Licensing: The license does allow for educational reuse of the materials, as well as modifications and adaptations.

I would use this OER as a reference regarding basic biology concepts so as to have a reliable source to go to instead of simply “googling” terms or querries.  It is searchable, has clearly defined sections, and was put together by a professional that is very familiar with the material, and strives to keep it all up to date.

I personally use OER’s in my own life for many of the DIY prjects that I take up.  This includes minor home repair, as well as simple programming, like setting up and using a Raspberry Pi.  The OER’s available I find very useful for my own educational purposes.  I also use OER’s when applicable for creating content for a variety of the course assignments I I’m given, for example creating PowerPoint presentations, or in class educational activities.

First Reflection

I found the difference between instructor-centered learning and student-centered learning very interesting.  It seems that with Instructor-centered learning there is a risk of students “zoning-out”, or losing focus, more so at least than if they were guiding their own learning.  However, when learning is student led, there is a higher risk of erroneous information being learned and never being corrected, resulting in a much less efficient learning outcome.  It seems that a mix of the two is best, with an instructor there to watch for wrong information being learned, but allowing a more active role by the student of teaching themselves the content, stepping in to clarify when a concept is too complex.  This also would vary significantly between subjects, like academic learning, cognitive processes, or athletic and physical activities.

The difference between synchronous learning and synchronous learning seems to be much more one of convenience.  In an ideal scenario, students would have all the time to dedicate to learning that was required, and different subjects would have ideal schedules for how to learn them (for example, learning a sport takes significant training, and you can’t do all of it in one day, but also can’t split it up into 5 minute increments over too long a period).  With working adults having drastically different schedules and availability, asynchronous learning helps each individual to accomplish the required learning activities within the time that they have available, without a need to excessively reschedule their lives.

With the advent of how accessible information is in our current day and age, along with the incredible amount of new information becoming available every year, connectivism seems to offer clear advantages over other more classical learning theories.  Other learning theories, like behaviorism, cognitivism and constructivism have a clear focus on the ability to either internalize information, behave in a manner that expresses the learning of something, or an ability to externalize information already learned.  All three focus on the information permeating an individual, which is a process that can take a long time, time which renders information currently being produced as irrelevant more rapidly than allows it to be fully learned.  In connectivism, the focus is instead on how information can be gathered from different sources.  Classically, this would have made very little sense, in a world where information was largely stored on books and digital media didn’t yet exist.  However, nowadays, with the internet at our fingertips, the ability to quickly gather, interpret, and apply information is of incredible importance.  Connectivism focuses on information flowing, from sources to the right people needing it to carry out action in organizations.  Carrying vast amounts of information within one’s head is no longer an ability of value when compared to being able to call up necessary information, understanding it, and applying it.  I think connectivism is a valuable perspective to have going forward regarding how to interact with information.  However, our educational institutions are still behind when it comes to training connectivism, and many grading and teaching methods still rely on older perspectives of knowledge acquisition, which are not preparing people for the challenges they’ll face in the work environment upon graduation.
