Affordances Analysis

I am going to explore the affordances and disaffordances of blogging. Now, blogging is something that I have yet to employ but am planning on using this coming Fall semester.

Affordances of blogging.

Blogging affords students the opportunity to share videos and articles with each other.
Blogging affords discussions of shared videos.
Blogging affords electronic submission of assignments.
Blogging affords archiving and organization of post and submissions.
Blogging affords easily responding to or commenting on submissions.
Blogging affords students the opportunity to read each other's submissions and see different perspectives.
Blogging affords a more casual writing style than "normal" writing assignments.
Blogging affords a less stressful writing process compared to formally typed and printed assignments.
Blogging affords posting videos used in class so students can go back to them if they please.
Blogging affords students the opportunity to see that an assignment is due even if they weren't in class when it was assigned.
Blogging affords students the opportunity to ask classmates what they missed if they weren't in class
Blogging affords sharing ideas with many people at once.
Blogging affords students the opportunity to collaborate with students from a different section.
Blogging affords the addition an afterthought to an assignment via commenting.
Blogging affords editing an entry once it has been submitted.
Blogging affords deletion of malicious comments by blog owner?

Disaffordances of blogging.

Well when it comes to the disaffordances of blogging, I think back to When Blogging Goes Bad..
Non-mandatory blogging affords no blogging at all.
Mandatory blogging disaffords the journal-like characteristics that normally define blogging.
Blogging affords anonymity, which affords malicious comments on posts.
Blogging affords students the opportunity to read each other's submissions, potentially causing the author anxiety.
Blogging affords access to people outside of the classroom network, which can also cause anxiety.
Blogging disaffords strictly enforcing deadlines (no way to prevent late postings).
Blogging disaffords a "final version" (can always go back and edit after submitting).
Blogging disaffords grading submitted assignments directly on site (lack of anonymity).
Blogging affords answer sharing.
Blogging disaffords group work.
Blogging affords making changes that may go unnoticed if a submission was already viewed.

And I'm sure there are probably more affordances/disaffordances that I haven't even thought of yet..

Fallen Angel: The affordances of a discontinued technology

I had many grand plans of what I might analyze the affordances of.  However, as I tossed about these ideas I have also been getting structure in place for my upcoming online course for the fall.  During this process I kept finding myself thinking about Angel.

It became clear that there were certain affordances of Angel that I wanted to hold on to.  However, there are also areas where Angel's affordances are lacking.

Centralized Communication

The first affordance that I want to discuss is the way Angel affords centralized communication.  With the selection of a few preferences I can insure that when I communicate with students through Angel they receive messages both through the Angel Communicate tab and their student email.

This lets me send one message that is delivered in several places.  An important note here is that neither Angel nor the student email is especially friendly when it comes to the mobile interfaces that many students use.

Secure Repository

The second affordance of Angel is that upon course creation establishes a secure place where course materials and student assignments can be kept.  A secure repository is important for logistical reasons (the college only wants registered students to take a class) and and it is an important part of establishing a safe writing environment (e.g. a student feels uncomfortable sharing their writing with the entire class during the writing process).

A secure repository also provides a space to collect copy righted materials for class use when public distribution for class would be frowned upon.  Note: A big challenge with Angel is there is no easy way for a 'public' space where students can choose to open their work up to a larger (unknown audience).

Varied Moderation

Being able to vary the types and kinds of moderation of class discussion is another important affordance of Angel.  Whether I want to have a closely moderated discussion group for the entire class or areas where only small groups can have conversations privately Angel supports moderation that can support these types of activities.

Another part of a big challenge with Angel mentioned previously, is that in addition to not affording a 'public' space, there are not easy ways to moderate or established public dialog.  This is an activity that Tumblr easily affords.

Levels of Visibility

When working on creating a course or changing parts of an established course structure the fact that Angel affords different levels of visibility is important.  Being able to hide unfinished material or establish reveal dates or date ranges of visibility supports a wide range of activities.  As I organize a course I can create holding areas and only reveal what is finished or immediately needed by students.  This type of visibility lets me see course structure while not distracting students with changing folder contents.  Changing visibility also helps combat information overload by letting me reveal items that become important as we move through a project and hide items that are no longer needed.

Affording visibility in Angel does not extend pass the password protected bounds of the institution.  Although it is easy to add students and other faculty from within the institution, extending access to 'outsiders' or the public as mentioned early is not easily supported.

Let’s Be Friends? The Affordances & Disaffordances of Facebook as an Online Educational Tool



Facebook is one of those tools that many educators cringe at using in the classroom. As a social media network, the idea of incorporating students private lives and friendships into the sometimes stale classroom can be worrisome. Professors may feel that by asking students to connect and use Facebook is an invitation to have them enter (and I quote Bill here) “the professors creepy tree house”. But once getting over these initial fears, professors and students can find several affordances of incorporating Facebook into the classroom. While no doubt some disaffordances exist and some professors may opt to use a different online system such as piazza.com or voki.com, the vast literacy students (and most professors) have with Facebook makes it an arguable tool to use over other sites.

But before I get on my soapbox proclaiming the wonders of Facebook, let’s take a look at some of its disaffordances. (For I too was once a teacher who looked at the inclusion of Facebook in my course with skeptical eyes.)

Disaffordances (And Then A Critique of the Disaffordances)

“The Creep Professor Syndrome”- As I briefly mentioned above, asking students to join a Facebook group can feel at times like the professor is asking students to join a secret group. More importantly, since it is the professor asking them to join the group students may feel pressured to join and feel as if their private world of Facebook is being put under-siege by an academic outsider who ultimately controls their grade.

While I recognize this concern, a way to avoid feeling like a “creepy” professor is by asking students if they would like a Facebook page. Doing so, places the tool as an option and not as a mandatory site. From my experience, nearly every student finds using Facebook in the classroom is a great idea. Now, I recognize this reaction may be due to my age and gender, but with the frequency students visit Facebook I would put money that most students no matter what the age or gender of the professor would most likely respond positively to using Facebook.

Privacy Issues- This goes slightly hand-in-hand with the “Creepy Professor Syndrome” but no doubt is an issue. Facebook changes frequently and as such so does their privacy settings. This can often times release information that is intended to be private into a very very public world. Thus, there are legitimate concerns about privacy settings with Facebook. Additionally, some fear that Facebook may violate FERPA, which protects student’s privacy and rights in educational settings.

While these are legitimate concerns, there are solutions to working around privacy issues. Yes, Facebook changes quickly and so does the privacy settings. But so does all technology. My argument is that if you plan on incorporating technology into the classroom then you are also signing up to continually educate yourself and keep on speed with the technology that you are using. Yes, that takes more time and, at points, can be very frustrating. But it is a reality that is hard to escape.

Additionally, Facebook can be used in a way that does not require the student and the teacher become “friends”. Instead, you can create a class group where you as well as the students can post information, documents, updates, and create events. This group can be protected either as a “secret” group where no one can see the group or a “closed” group where all members must be approved to join. This avoids non-students or pesky members to join the group and create external class distractions. Creating a group then avoids teachers feeling the need to “friend” their students or students needing to “friend” their teachers. Instead, the group becomes an external meeting space for teachers and students to use for classroom purposes.

Finally, the issue of FERPA is a serious one. However, make the Facebook group and use optional. Doing so should release teachers any penalties of violating FERPA laws. Additionally, it places less pressure on the students and teachers – avoiding feelings of joining an unwanted group or site.

Access- This disaffordance is an issue though I would like to argue one that is subsiding. Yes, access is always an issue especially with the digital divide. However, teaching in higher education settings I believe minimizes issues of access. Once students enter college-level courses, most (if not all) universities expect students to have access to the Internet in some form or another. For example, MSU as an institution mandates that freshman have a laptop once they begin courses. But this is talking about technology in general. Let’s get back to Facebook and access. If you are thinking about incorporating Facebook into your class, I encourage you to take a quick poll in your class to see how many of your students use Facebook. From my experience teaching at MSU, the numbers are near 99% if not 100%. These college-level students have Facebook and use it often (even during your lecture in class). Now there may be some students who simply don’t have it or don’t want to use it, and this is a legitimate access issue. However, by making the Facebook tool optional and not mandatory avoids issues of access. Instead, it simply becomes an extra tool to use. In my own class, I make it policy that whatever I post to the Facebook page I will also send out in an email to the whole class. This then ensures that students will always have access to class information.

Distractions- This relates a little to access as well. Many students, especially college students, are using Facebook in class, on their phones, at work. It is everywhere. As such, some professors may argue that by incorporating Facebook into the classroom then encourages more distractions as they are teaching. However, my counterargument to that is these students would be using Facebook no matter what during class. Therefore, why not create a Facebook space for these students to use during (and outside) of class time? We live in a digital world where distractions can no longer be fought against. It is simply part of our everyday nature, simply look at the number of tabs you have open on your computer screen right now. (I have 13 open right now and it is only 9:30am!) Therefore, instead of wasting time in class trying to fight against the distractions of online worlds, we should attempt to try and incorporate them into our classroom spaces. Doing so may allow students to continue to feel a weird comfort level of being distracted but being connected to the class at the same time. Instead of looking at photos of their friends at a party over the weekend on Facebook, they can be looking at a new class prompt or discussion question posted to the Facebook page as lecture is going on. In a world filled with distractions, it is something to legitimately think about.

This now brings me to a set of affordances. Yes, I have tried to counter all of the claims that are disaffordances to Facebook and now will attempt to convince of the multitude of affordances.

Affordances:
Ditch Angel/D2L/Blackboard – Many professors and students find it hard to actually want to use a non-customizable system like Angel, D2L or Blackboard. The mobility of the sites are stiff, unfriendly, and out-of-date. To paraphrase Neal, it is very much like having an old kitchen where no one wants nor is inspired to cook. This is why Facebook as a tool is unique as it allows students and teachers to pretty much ditch the system! On Facebook, course updates can be posted (like emails), documents such as readings and worksheets can be uploaded, student discussions can occur, class chats too, as well as editing of documents. Further, unlike other systems, all class activity on the page is recorded and becomes a class log to an extent for teachers and students to reference throughout the course. In a way, the page contains “live notes” that constantly live, change and stored for reference.

As a teacher using Facebook, this is the largest affordance. No longer do I need to login to Angel, direct myself to the email tab, select students I want to email, compose the email, and then send the email. Instead with Facebook, all that is needed is the ability to login to the site, post an update and I’m done!

Updates- A great feature of Facebook is that it automatically updates all members of the group. When a student posts material or a question on the page, immediately I am sent an email and am directed to that post. The same works if the teacher posts anything. Students will receive an email and be directed to the teacher’s post. Personally, I find this feature to be quite beneficial because it ensures that I am constantly connected to the actions of the page. This then minimizes inappropriate use of the site as well as offers an immediate connection. This I find important especially for an online course where it can be easy for teachers and students to check out. With updates linked to email and available on the Facebook page, checking out simply is not an option.

Limit Email – The affordance of updates works to limit the amount of email the teacher must respond to. Now, you probably ask yourself, how is this possible if I am getting email updates from the page? Well, the reason is that often times while you receive those updates you do not need to respond to them.  Here is an example of how students use the Facebook page and how the site helps to “decenter the classroom”.  Jerry asks, “Can anyone tell me how to post stuff to the blog?” Samantha responds, “Go to our pages dashboard then find ‘posts’ and then ‘new post’”. She adds later on in the night “message me if you are still confused”. Here the teacher received email updates of such activity occurring on the page. However, since the activity took place at 9:30pm when the teacher was no longer checking student emails, the students themselves where able to provide correct information and appropriately direct the student to the correct page. As such, in the morning, the teacher only needed to login to Facebook, see the post and the response in order to ensure proper direction was given. In this instance, Samantha not only correctly directed the student but also extended herself to act as the teacher in this instance. Such an affordance is unique to Facebook as a tool and one of the primary reasons why I use it in my courses. (Please note, student names were changed in order to ensure privacy.)

Mobile – A final affordance is that Facebook can and often is used on mobile devices. This allows teachers to post updates directly from their phone instead of hauling out a laptop or logging into Angel to find email addresses. Instead, class updates are available at teacher and student fingertips. Again, this limits the amount of time students and teachers need to spend to simply ask a question or post a response. And for writing teachers especially who need to grade numerous papers and of which the time to do so is incredibly tedious, using Facebook as a tool to minimize basic class management is something very appealing.

Affordance Analysis: PowerPoint


Here’s a far from exhaustive affordance analysis of the dreaded PowerPoint presentation.

AFFORDANCES:

Accessibility: To me PowerPoint’s great asset is its accessibility. PowerPoint files are påretty ubiquitous and can be opened with GoogleDocs if students don’t have the Microsoft version on their computer, which makes them sharable. You’ll find PowerPoint on most institutional computers, so it’s crazy to assign an assignment using PowerPoint. People, as a rule, don’t seem daunted by PowerPoint as a software, which is good. Basically, if you can use a word processing program and have some knowledge of file importing, you can make a pretty robust presentation. Presentations are also printable, which allows students a tangible take-away from the presentation and a place to store their notes.

Updatability: Hopefully we’re in the practice of constantly updating our teaching materials - keeping them fresh and relevant. PowerPoint’s pretty simple and easy to update.

Visibility: PowerPoint’s layouts are pretty fool proof, which makes creating easy to follow presentations a snap. Visual rhetoricians might not necessarily agree, but I think the templates make for, at minimum, legible presentations.

Multi-modal-ability (or something): For a fairly simple interface, PowerPoint allows users to do a number of sophisticated things. Users can import still images, sounds, animations, video, etc., which can make for pretty dynamic presentations. By incorporating different modalities, of course, we can reach students with different attention spans and learning styles.

DISAFFORDANCES:


Lack of Student Center-ability: I read this web article by a professor from Minnesota and he makes a good point: if one of your pedagogical standards is that students play an active and central role in the classroom dynamic, then PowerPoint might not be the most suitable technology. That’s because it’s pretty limited in the sort of interactions it encourages. Really, PowerPoint’s bread and butter is the one-to-many, presentation-style interaction which is fine. And, sure, questions can be posted on the PowerPoint to facilitate other types of interaction. But it’s not the most organic technology in the world. PowerPoint presentations solidify hierarchical structures in classrooms, which, depending on the class, could be undesirable.

Lack of Round-about-ability: PowerPoint presentations are linear by nature. Again, this is fine. But there’s something to be said about a recursive teaching or presentation style. Perhaps PowerPoint is a little limiting in the very direct way it takes a presentation from Point A to Point B. Learning very rarely happens in a straight line. In fact, it more than likely happens in loops and is recursive like writing. PowerPoint's not built for that.

Template Fatigue-ability: I doubt I’m alone in thinking that PowerPoints can be pretty boring. So many presentations cut out of the same piece of cloth. Even though PowerPoint allows for creativity, many of the key tenets of a PowerPoint are pretty predictable. I think this can lead to, among other things, students losing interest, taking parts of the presentation for granted, and generally thinking “Oh, here we go again, another boring presentation.” Even if the presentation is well made, well thought out, and interactive, it may fall victim to “guilt by association.” This might also be called stagnate-ability.

Lack of Universal Accessibility: Because it’s highly visual, PowerPoints may pose problems for people with certain disabilities like color blindness, dyslexia, vision impairment, etc. Using it as a stand alone presentation platform (or using it without consideration of its possible impediments) could lead to an unfair learning environment.

SUMMARY:

PowerPoint is a pretty valuable and dynamic piece of software, but I think it’s safe to say that it has to be used judiciously and in harmony with your teaching and learning goals. From a practical vantage point it has some pretty important affordances, but those affordances have to be weighed against the possible risks. One way to conceptualize the use of PowerPoins in classrooms is to think of it in terms of form and function - always placing function before form. I think there’s a tendency to fall back of PowerPoint because it’s so easy and quick to create professional, crisp-looking presentations. But, ease of use has led to many a bad teaching technique (WORKSHEETS anyone?). PowerPoint should only be deployed, in my opinion, if it fits correctly into your predetermined interaction grid and should not be utilized as a quick-fix.
