Teaching Programming with BYOD

Bring Your Own Device.  It is a solution and it is a problem.  All my programming classes are BYOD.  I have loaner laptops for those that cannot afford a laptop but that really is not much different from BYOD.

Why BYOD?  Many reasons.  The school has two computer labs.  One is in a classroom so it is out.  The main school lab is pretty sterile, computers in rows elbow to elbow.  Just not what I would consider an atmosphere for thought and exploration.  It is also used regularly so putting a programming class in there is going to be a pain for other teachers.  I used to have computers lining the walls of the room in which I teach.  I would install all the software and have things pretty cookbook.  But then I had problems with privileges when the kids wanted a sprite, needed to save locally, saving on Google Drive and half a dozen other issues because the kids were not administrators.  I wanted the kids to learn how to download and install the software they were using.  Getting Python up and running with an editor is not always a trivial exercise.  The kids should know how to troubleshoot an install.  BYOD allows those that want to work at home to do so.  Admittedly I do not get a large number of those students but there are enough to justify the BYOD hassle.  Perhaps the biggest reason for BYOD is I want the kids to know about their device.  The kids can run apps, download from Steam and get Netflix to work but changing resolution, hooking up a second monitor in extended display and installing a Google Drive folder are not tasks the techno generation seem familiar with.  So BYOD it is.

A big advantage of BYOD is the kids that own their own laptop (most of them) have a better device than anything the school owns.  There is just something about working on an i7 with 16 GB of RAM and a dedicated video processor that make a Python or Unity assignment run better than on one of the ten year old school loaner laptops or lab towers.  The only way I get to see really cool hardware is when a kids brings it in.  BYOD eliminates any administrator install issues (unless the computer has something like Network Nanny on it.  I had a long discussion with a parent over that one.)

The big disadvantage of BYOD is you are now dealing with five different brands, weird malware, fourteen viruses and a partridge in a pear tree.  I actually like dealing with all these issues.  At the beginning of the semester the kids learn all sorts of software and hardware issues.  Cool.  Another somewhat interesting disadvantage is the kids that are working on 11-inch computers.  My eyes do not see that small any more.  A Unity project on an 11-inch screen is just silly.  Then there is the kid with the Mac.  Kid, you are on your own.  If you want to borrow a PC I have some.  Even worse is the kid with the Chromebook.  It is always an interesting conversation with the parents about how that new, cheap Chromebook is not going to do the trick for anything we are going to do in my programming classes.  A sad, sad moment.

Some lessons learned:

  1. Teach file management. The kids keep forgetting where they save things or they scatter files everywhere.
  2. Stress saving to Google Drive or the like. Backpacks are rough on computers and I have had a couple kids kill their computers by not being careful.  Bad, very bad.
  3. They need a mouse. Trying to do something like Unity without a mouse is not practical.
  4. Bring the power cord every day.
  5. All sorts of things are on that BYOD laptop so watch them like a hawk.
  6. Expect weird issues so be flexible.
  7. Have some kind of central file storage area for assignments, YouTube videos and what not the kids can have access to. Something like Google Classroom or a Google shared folder.
  8. Have enough power outlets in the room. My school was built in 1922.  Electricity was a fad at the time.  The classrooms have two outlets.  I had to have maintenance run conduit and outlets around the room.  Laptops do not pull a lot of amperage so there is no problem with the breaker.
  9. The internet content filter is going to cause a problem. Be on a first name basis with the person that controls it.  In my case it is me.
  10. Read #6 again. Several times.

After several years of BYOD programming I would never do it any other way.  Yes, it can be a pain at times but the advantages for the student far outweigh that pain.

    Great topic. It’s always 1, 6, 9, even without BYOD. My son’s hs cs class would have gone better as BYOD as IT dragged their feet at installing software for the class.

    I always wished we could have done BYOD when I was at Stuy. I was able to work around the problem with my students now at Hunter College since the students in my honors program get laptops as part of the deal. It’s the best of all worlds since they all get the same laptop, if they’d rather use their own, it’s up to them to get it to work.

    Even if a school or laptop isn’t doing BYOD you still have to do deal with all sorts of install problems since the kids need to have access to the tools from home. It’s actually easier to have a laptop so we can see the problem live and in person.
