Note: This post is an exercise in my meandering thoughts. I usually try to bring these around to something practical, but I'm not sure this is one of those times. You've been warned, but you are also reading a blog called "On the Rabbit Trail," so maybe that is to be expected.
Edu Twitter is predictable. At certain times of year, you can rely on certain trends or arguments. Some are legitimate discussions about pedagogy (learning styles, discovery, etc.) and classroom practice (deadlines, cold calling) while others are just preferences disguised as debates (when you should and should not answer your email is the teacher equivalent of where to squeeze the toothpaste). In most of these debates, opinions are high and acceptance for the opinions of others is often low.
Occasionally, there is one that is more intriguing than others. In this case, it isn't about whether something is right or more effective, but about whether it is easier. What I find interesting about that discussion is that it seems like a straightforward question, it more complex than you might think. When the question is about effectiveness, experiments can be set up, and test results can be analyzed. But the question about whether something is easier is largely based on perception and that perception is shaped by multiple factors.
The question is "Is explicit teaching easier for the teacher than discovery learning?"
Let's define our terms - Both explicit teaching and discovery are terms loaded with academic jargon and emotional baggage, so let me define what we mean in this discussion.
- Explicit teaching - It is not the same as lecturing, but it is often confused for it because the teacher is standing at the front of the room explaining things. What's the difference, a lecture is all in one direction and has no interaction with the students. Think of it this way: If you could have delivered the same lesson after hitting play on a video of yourself teaching, that's a lecture. Explicity teaching (sometimes called direct instruction with a small d and i because capital DI is specific scripted program) is very interactive, pausing frequently for formative assessment and retrieval practice to make sure students understand and will remember what the teacher is teaching.
- Discovery learning - People on my side of this argument often set up the straw man of assuming a proponent of discovery learning is talking about "pure discovery." Pure discovery would meant the teacher goes in with no preconceived notion of what students will learn and allows them to just freely explore. I say this is a straw man because I have NEVER seen anyone do this in practice. Even the most ardent fans of discovery learning I know go in with a plan for the outcomes and fences around their playground. So, in practice, what we are talking about is "guided discovery," in which the teacher is setting the destination but allowing students to get there is a variety of ways.
When Done Well . . . This may be the most common (not to mention meaningless) phrase used in the eduTwittersphere. No matter what the discussion, someone will come along and say, "When done well, this is effective." Well, duh. Anything done well is going to be more effective than the same thing done poorly. For that matter, even a poor practice "done well" will be more effective than a good practice "done poorly."
In the case of this discussion about what is easier, it's an even dumber phrase. Doing something well requires effort, energy, organization, and time. Doing it poorly usually results from the lack of those inputs. So, either "done well" is harder than the other "done poorly."
So, let's set that argument aside and assume two classrooms, one employing explicit teaching and the other employing guided discovery, but both being done as well as they can be. In other words, both being "done well." Let's look at the factors that might make one style of teaching easier than another.
1. Lesson content - Some lessons lend themselves better to discovery than others. If I want students to know what factors influence rate of dissolving, it is not hard to set up an experience that will allow them to time how long it takes to dissolve a cube of sugar in hot water v. cold, while stirring v. keeping it stationary, and keeping the cube whole v. crushing the cube into powder. While I wouldn't say that is easier than explicitly telling them those factors, it might be worth the effort. But if I want them to learn the underlying empirical formulae for ionic compounds, it is going to be difficult to learn through discovery. I'll grant that it was originally learned that way, but that was by scientists who devoted months and years to one substance, not high school students in a class period. So, in instances like this, explicit instruction would be much easier.
2. The students - We all have one class that is, how shall we put this diplomatically, more challenging than the others. It could be the class you have righter after lunch or the one you have the last period of the day. You know the one I'm talking about though. They are the ones that make you want to pull your hair out when there is still 30 minutes of class yet. As a young teacher, I thought they would be the ones to benefit from discovery because the needed to move and talk more. Oh, my! Was I ever wrong?!?! That was the opposite of what should have been happening. My life became so much harder than I ever imagined.
3. Teacher personality - We always find a thing we love to do easier than a thing we don't. We get in a zone and things just seem to flow. If you are a teacher who loves explicit lessons, it is not going to feel hard for you to plan one. You are going to enjoy coming up with metaphors and planning your questions. This will feel easier for you. For my friend, Hannah, planning a purely explicit lesson would be torture. She loves the process of giving her kids something mysterious and pulling the concepts out of them. For her, this will seem easier (even though it objectively takes more energy) because she finds it energizing. For her, discovery teaching is easier.
