Distance Teaching (Surprise!) and COVID-19

If you have Canvas, use its built-in quiz tool. It can do automated grading, or you can grade manually. It’s pretty good. Students like it because its right there in the course space. The downside is that it’s not a great fit for most STEM courses. If you need to do multiple choice, or even short typed answers, anything from Google Forms to Canvas can work very nicely.

For traditional STEM courses where problem solving is the goal, you’ll need to do a bit more work. One of the simplest solution is to have students take a photo with their phone, convert it to a PDF and then upload it through your LMS (Canvas, Blackboard, etc.) Recommend one of the free apps that make this easy. I really like Scannable for iOS – it adjusts contrast, perspective and cropping automatically, and automatically stitches multiple pages into a single document. There are similar apps for Android. In fact, I’ve stopped using my big office copier/scanner because my phone and the app was faster and gave me similar quality.

Jupyter notebooks are also quite good for this as well, particularly if you’re replacing a lab assignment. Students take photos of their work and add them to the notebook, provide their formal report, and can do data analysis and the like in the notebook if they has experience with python, etc. Or just have them assemble them in their tool of choice (Office, Google Docs, etc.) and send you a PDF.

One of the bigger challenges with large classes is simply organizing the work that comes in for ease of grading and returning it to students. That’s really what your LMS helps most with, but if you don’t have one, and need to rely on emailed assignments, etc. make sure you give them some hard rules on file naming and such. One of the big challenges at my institution is each student has two IDs – their numerical student ID and the first part of their campus email. Different systems sort on different IDs. Do yourself a favor and have them name the file [ID]-[Assignment Number] so that you can easily organize the assignments into different folders and sort them on your computer to match your gradebook. If you have TAs, that can help divide up the work if you normally work with paper assignments.  Consider a file sharing tool like DropBox that allows you to do file requests so their emailed files will all drop into a folder for you: https://help.dropbox.com/files-folders/share/create-file-request#filerequest Students don’t need a DropBox account. You can put a deadline on the request and submit to multiple people so you can dump your whole roster in there.

Writing assignments are always challenging. Consider a service that can help with peer grading for formative work. Some LMSs have this built-in, Turnitin offers it as a service and there are 3rd party services such as www.peergrade.io. Find the ones that work best for you. Peer grading can help reduce the amount of review that you need to provide. There are a number of studies that show that peer grading does a servicable job at giving students feedback. In fact, you can shift your approach a little bit and use the quality of peer feedback the student gives as part of the grade, just to ensure they take it seriously.

My instructors really like Canvas Speedgrader once they get it all set up. It’s a bit of work to get set up, and required them to change their approach a little bit, but the payoff was worth it. Students upload their assignments as PDFs, my instructors use an iPad Pro with Pencil to load the assignment, mark it up just like a paper assignment, submit the grade, and return the work to the student. It removes a lot of the administrative overhead of grading, and works very well for both writing and for traditional STEM problem solving assignments. It also works well for take-home exams.  You really do want a tablet with decent pen input though – iPad Pro, Surface Pro, some Samsung tablets, some convertible laptops all work well. Not a cheap setup, but we’ve been able to reduce the number of graders and readers doing this becuase a surprising amount of their workload is actually just taking a stack of paper assignments and sorting them, etc. and here the computer does all of that adminsitrative stuff for you and allows everyone to focus on assessment and grading.

Summative Assessment

Here’s where things get hard. Test taking services like ProctorU are appealing and do work pretty well in most situations, but have a few drawbacks you should consider. These services work by having students install a piece of software on their Mac or PC that takes control of the computer, preventing students from switching into other apps. It also take over their microphone and camera so that a person at a workstation can monitor the student, just as you do when proctoring an exam. The student needs to show the proctor they have no study aids around, that there is nobody else in the room with them and the proctor enforces a time limit on the exam. The exam is in a web browser and students submit their answers online, which you get in electronic form. The caveats:

1) I do not think they can scale to the current situation. Unlike Zoom which is a matter of spinning up new servers, ProctorU and similar services need to have a person monitoring students – they usually monitor roughly a dozen students at time. I’m skeptical they can staff up and add workstations for the current situation given that almost everyone holds exams in the same few weeks. I would do extra effort to ensure they can handle your course.

2) It works well for multiple choice, short answer, essay – things that can either be easily typed or run through a scantron. It does not work well for problem solving, equations, sketching a diagram, etc. We have worked around that by having the student type in the final answer to each problem, and then taking a picture of their work product with their phone as I describe above and upload that with the exam. They have to do this within 15 minutes of completing the exam. It works, but we’ve never tried it a scale more than a few dozen students, and you don’t get the benefit of easy organization of work materials that your LMS offers.

3) It costs $15-$30 per exam. This is a serious issue at my institution where we have a tremendous number of low income students and being a public, we don’t spring unexpected costs on them. Putting out up to $120 for a set of four finals is something we don’t ask students to do.

We’re advising switching to a paper/project final if you’re about to start a new quarter. If you can make the quiz tool in Canvas work for your final, that’s another good option. Otherwise we’re advising designing an open-book final that students upload through the LMS as a PDF. You may still want a timed final during your scheduled final exam window, and for our instructors they can still do that, but we ask them to give students some leeway on time due to problem with uploading, etc. For project courses we’re adapting an existing strategy that we use. Our project teams normally make a weekly 2 minute presentation on the status of their project, what they did in the last week, and what they are working on in the next week, and noting any new problems that developed. It’s designed to be short so they’ll have to actually put effort into it since they can’t just ramble, and the instructor has a few minutes to ask questions. It’s our way of keeping projects on track. We’re expanding that concept to the final project – students will either put together a video showing their project, addressing specific requirements as part of the course, or doing an interactive Zoom presentation where the instructor can ask questions. The former for larger courses, the latter for smaller ones. Basically, an oral exam. My son is currently doing an animation in Blender illustrating how his project works. You’ll be shocked at the skills your students have if you give them room to be creative.

There’s a lot of other cool ideas and services out there, but they require a lot more prepration and rethinking of how a course is taught. Continuous assessment is the future in a lot of areas, and I’m a big fan, but that’s for another day.

My creds – I am a law professor who, for three and a half years during massive institutional upheaval, acted as the Vice Provost for Faculty and Curriculum at my “Mid-Size Comprehensive University” (about 6000 undergrads and another 3000 grad students including law).  I was inter alia, responsible for our Center for Teaching Excellence and was also put in charge of our school’s creation and expansion of online offerings, Hybrid classes, and MOOC productions.  We also prepared a proposal for creating an in-house online production unit with the goal of starting a non-degree university extension program (certificates and specialty areas).  Well, the Higher Ed. Crash of 2013-ish put most of those projects on ice, but I still learned a lot!

And I am hoping to share some of what I learned with you.  In this first post, the plan is to start off with some basic definitions, then offer some ideas about where to start your new design.  I also will briefly mention online assessments.  We really will need another full thread focused on tech – but even now get to know your institution’s Learning Management System (LMS)!

First, so we can all be on the same page in this discussion, let’s discuss some terms.  I know many institutions use variations on these, but I will use the following terms:

F2F – Face to face, in person, teaching.  What we all currently think of as how education happens.  There are all sorts of different methods that can be employed in such a class – lecture, Socratic method, image-based learning (remember the old art-history course slide decks?), Team-Based Learning (not to be confused with group projects), discussion leaders, etc.  There are a LOT of F2F pedagogies, and every teacher has their favorite or blend of favorites in the classes.

Hybrid – This is also often referred to as a “flipped” classroom.  In a hybrid course, the idea is to take a great deal of the knowledge learning out of the classroom (minimal lecturing) forcing students to do their learning work before any F2F meeting.  In the Hybrid model, the idea is to have fewer F2F meetings, but maintain the same learning level among students.  There was a large double-blind Carnegie study regarding statistics that demonstrated that Hybrid methods improved learning outcomes.  Institutions liked it because it meant you might be able to double faculty class sizes without them having to increase teaching loads.

Online Synchronous – This is what most people think of when they first think of online teaching.  And it may be the way, in some cases, to go.  A professor teaches a course, often to a live audience, while a further audience is ‘attending’ the course via the internet at the same time.  This is the Harvard Extension School model of online education.  Now, however, the same thing might be done without any live audience – just people webbing in to watch a lecture or demonstration.

Online Asynchronous – This is the Kahn Academy model of online teaching – lectures about topics, or even whole courses, that can be viewed or heard at any time by the learner either on the intertubes or after download.  There are obvious convenience advantages for the learners, but the relationship between the teacher and the student may be limited, or non-existent.  Imagine if you could still take a course from Dr. Carl Sagan! Well, you can, but he doesn’t have office hours….

MOOC – “Massive Open Online Course.” The MOOC was pitched as a democratic solution to some education ideas.  And it can work, BUT – really good MOOCs are expensive to produce and really only suited to evergreen topics (more on this later).   Luckily, MIT and Harvard started a joint project around the promise of MOOCs called EdX.  Their business model wasn’t great – but their course research and data are phenomenal, and their baseline conclusions can be very useful for you as you get ready to go online.

Assessments – OK, tests.  But not all tests need be graded, at least not by the teacher.  There are formative assessments – that solidify learning; and there are summative assessments that are intended to rate the learning.  I am putting up a PowerPoint I once did about assessment on the vertical (how are students doing in the course) and on the horizontal (how does my course fit into the overall learning objectives of the program in which I am teaching).  In both axis both formative and summative assessments can be designed to help your students and help you make a better course.

So, with some of the lingo out of the way, let’s talk about your class.  Most everyone (some lab instruction excluded) are now moving to fully online – not even the version where there is a live and online synchronous audience.  At least at my University, Professors have been told not to let students sit in the classroom while they are recording their class, even if it is a synchronous course being taught at the regular class time, in the regular classroom while being simulcast on the web.  Students just are not welcome on the campus right now if that can be avoided.  Some schools are pushing their faculty to do this and offer your online whatever only during your regularly scheduled class time.  I get the impulse.  Students are already into a regular schedule and keeping them on the same schedule is probably a good idea – but, not necessarily the best way to convey your lessons.  If you are required to produce synchronous pre-scheduled material, your challenges are different than if you can present the course in a completely asynchronous fashion of a blend of the two.

Designing an online course may feel daunting because of the technology, but let’s push that off for a moment.  The tech can follow your design.  When I was a kid, there was a Saturday morning show of international children programs. One of the foreign segments was about a boy in the Australian Outback with many wonderful animals.  But he still had to go to school!  Which was via the shortwave radio in the family room of their home.  It was question/answer and lecture.  Please don’t teach online like you are using a shortwave.  Sadly, many of my colleagues teach exactly like that.   F2F.  It will be boring for you and twice that for your students.

Backwards Design Your Course

First, go backwards.  Most teachers know this concept now – in fact, I think the younger the students you teach, the more you have been trained to course design in this fashion.

FIRST – What is/are the overarching GOAL of the course

SECOND – What are the OBJECTIVES related to each goal

THIRD – What TASKS of learning will be assigned or recommended to achieve each objective?

FOURTH – what assessments will you deploy to monitor student achievement of the tasks, objectives and goals.

You are now done designing your course! 😊  We can talk a lot more about specific online course designs later, but let’s get something ready for the next week?

Conveying Knowledge

Now how does this go online?  Your first step is to get a clear idea of the capacities in your Learning Management System (LMS).  We use Blackboard, I like Canvas, and many public schools in my area are using Schoology.  They all offer roughly the same suite of apps, with each product emphasizing this or that functionality.  In many cases, an online course could be designed entirely around the functions available in your LMS.  The most critical ones for a quick online setup will be the boards, or comment sections.  You all blog, so this should be a natural!  Every LMS has the capability of tracking responses and student engagement.  They also all have some capacity for assessments, usually including timed “check out” testing where students can take a test out but only have a limited time to complete.  Colleges use such systems for language proficiency exams now.  You could spin up a completely acceptable online course completely within your LMS – especially if it allows links to external content.  Considering the rush, I urge those who have flexibility to use the least complicated technologies as you start and save more complex tech (like Zoom) which require more tech support, set up time, etc. to take full advantage of.  So, you first step is to take your re-designed course and figure out how to get the learning to the students.

Back to the Evergreen! – In the future, which is now being catapulted by this crisis, the best courses will have all their evergreen material online.  All of it.  Evergreen material is that which does not change from class to class – like “There are nine members of the US Supreme Court.”  That may change some day, but it has been true for a very long time and will not switch anytime soon.  It is safe to consider this “knowledge” that can be put online as an evergreen fact.  It is a waste of everyone’s time to lecture about material in a roomful of students when they could learn that material outside the classroom.  This is, in theory, the first step of the Socratic method – students should learn everything they can from the assigned material and then classroom time is spent testing, challenging, and confounding that “knowledge” by the Professor.  Of course, that is not how it works, but how it should.  And it doesn’t work that way because most teachers teach like they were taught which included a very heavy amount of knowledge transfer from teacher to student in the classroom, often in lecture format.  So, first identify all the lecture material you generally deliver and put it online.  Students do not need to look at your shayna punim while you deliver this information!  In fact, it is probably better if you do NOT record yourself YouTube-style sitting in front of your computer lecturing.

My suggestion for the easiest rollout?  – make a podcast of your lecture materials. These can be heard anywhere – train, gym, bathtub – without the need for anything more than a phone.  Then, in your LMS, put up an outline or PowerPoint of that podcast lecture.  Your students will learn more and thank you for doing it. But, as mentioned by other commenters on Thursday – do not make your evergreen podcasts or viddys last longer than 15 minutes or so!  This is a very important learning reality.  The research (by EdX) suggests that the most optimal timer period for a learning module is 10-12 minutes followed by an assessment.  This creates the student learning that sticks in their brains.  15 minutes is a good target because there should be a quick preview and an overview bracketing the substance of your knowledge material.  Most teachers do this instinctively in class, mixing up knowledge transfer with other materials, anecdotes to make the material stick, other student interactions, etc.  Boredom and loss off interest is the mind killer….

Next up – we will post a more detailed something about the techniques of staying in touch (and being nice!) to your students (see the last link below).

A quick word on tech – What does your institution support?  Which technologies is your LMS most compatible with? (For example, many of my colleagues use and love Panopto (but it is more compatible with Canvas than it is with Blackboard).  So many people are discussing Zoom, but there are many other options for group meeting management.  Even Google GotoMeeting is good.  Skype also has such capacity for smaller groups.  Please do not get involved in a new technology in the middle of the semester if you or your school cannot support it

Generally, here are some nice online class primers with Zoom focus:
