The instructor gives the ok sign to each of us, one after the next, and waits for our mimed response. Next, he points two fingers at us and then at his eyes. Once he has everyone’s attention, he removes the second stage from his mouth and slowly blows out bubbles as he searches for his “missing” air supply. He finds it, puts it back in his mouth, and starts breathing normally again. Then, he points directly at my youngest child and signals for him to repeat the same actions. Nearby, I watch patiently, waiting for my turn, confident that, far from putting us in danger, this activity will make us all safer in the long run.
This week, my family is taking a scuba diving course. We’re learning a lot and I, of course, am busily observing both how we are instructed and how we are learning. I am always curious about how skills are taught outside of classrooms. Scuba is particularly fascinating because the consequences of not being able to perform the skills effectively can be deadly, but plenty of regular people scuba dive, so, while there can be no compromise, skills acquisition has to be manageable for all sorts of people.
Before we arrived on the island, all of us completed a five-section, multi-part online course with a final exam that we had to pass with a minimum of 75%. Each section built on previous sections for at least some of the learning (i.e., “How to be a Diver, part 3). As a family, we took four very different paths to success: one of us started early and learned methodically, using the “You will learn” introduction to each section to guide their reading, taking notes to learn “how not to die underwater”; one of us read the information in chunks, making sure they were able to pass the short required quiz at the end of each section before moving on; one of us skipped most of the reading but watched the videos for each section before “acing” the quizzes (not my word); and one of us went straight to the quizzes and tried them, then, once they knew what they didn’t know, went back to review only that section before completing the quizzes correctly and moving on. These choices were not obviously age-based, and no, I was not the one who took notes. We all passed the final exam, though one of us had to take it twice (72% then 80%). The last person finished the day we left on vacation. (Ok, that was a kid.)
If you’re keeping track… PADI (the group that administers the course)
- used a focus checklist (“by the end of this section, you will be able to…”)
- presented the information in both written and video format
- offered low-stakes immediate retrieval assessment questions (we could redo them as often as necessary)
- encouraged spaced practice by expecting us to review things we had learned in previous sections
- at the end of each of the five sections, offered more retrieval with a section quiz which we had to pass but could retake and THEN
- provided an evaluation which mimicked the section quizzes and which we had to pass with a 75%. If we needed to, we could review material and take it again.
That is decent pedagogy.
Today, we started the “practical” portion of the course with… wait for it… a written quiz based on the material we learned online. It was not for points. We simply took the quiz and then the instructor reviewed the answers and chatted with us about mistakes that anyone had made. For much of the information, this was at least the FOURTH time we had been asked to retrieve it. I don’t want to shock anyone, but we all passed this low-stakes review.
I’ll probably write more about the practical part of the course later, but I want to pause here and notice what I can take into the classroom from the written portion. For me, the lesson focus wasn’t particularly useful – I tended to skip that part – but one of my children loved using it to guide his attention. Interesting. We all spent different amounts of time with the information and took it in differently (I didn’t watch a single video; everyone else watched some or all of them). The low-stakes retrieval questions worked for all of us, as did the “do it until you pass” mastery quizzes at the end of each section and of the written course. The spaced practice was effective, too: if you’d forgotten something from a previous unit, you got a quick review in order to pass the current one.
I was most impressed, however, with the “extra” retrieval we did today. Let me tell you, everyone who took the course is very clear on the biggest ideas – and PADI has used both spaced practice and retrieval practice to ensure that we actually remember it.
Of course, a classroom is a different place. Most obviously, students’ motivation for learning in a classroom is not quite as compelling: rarely does anyone die because they forgot where to put a comma or mispronounced “epitome.” But I’m also thinking about how our family moved at different paces and took information in differently. That could happen in a classroom, to some extent. I think a lot about the Modern Classrooms Project, for example, which seems to account for some of that. My particular school is desperately low on technology, so I’m not quite ready to adopt the approach, but it seems right. I wonder what I could do to make learning in the classroom just a little more like getting ready to scuba dive?
Maybe I could just bring some really cool fish.
