Last week, while in class, I found myself becoming agitated with my students. They continued to ask the same questions about the same material…over and over again. I’m talking about asking the exact same question covering the same two or three terms/concepts. Brutal. Why were they not getting it? We weren’t covering anything too complex or difficult. How many times do I have to tell you the definitions for absolute threshold and difference threshold? Will I give you examples of each? Of course I’ll do it…again.
I think most of us have been there. It’s easy to become frustrated with a student, a group of students, or even an entire class that just doesn’t understand something that appears to be quite elementary. Explaining once or even twice is normal..but the need to revisit multiple times across several days is a bit much, right?
Enter the curse of knowledge. This term refers to “a cognitive bias that occurs when an individual, communicating with other individuals, unknowingly assumes that the others have the background to understand.” (1) Need an example of this? Reread the first paragraph. The nature of teaching lends itself to displays of this bias. I mean, I understand what I said…it makes sense to me. Why can you not understand it?
What we sometimes fail to understand ourselves, as educators, is that we have a well-developed schema for the material. We have organized much of the information that accompanies and supports specific knowledge of a concept/idea/term. Not only do we comprehend the meticulous details of the subject, but we also see how it all fits together in a larger picture. Our students, much of the time, have very immature schemas and this can cause the puzzle pieces of knowledge to not fit together correctly.*
Think back to when you initially experience new information. It can take a few explanations and perhaps a few examples to fully understand. Or consider how many times you may have to teach a particular aspect of your curriculum before you actually know and understand it. I know, for me, I only now really feel that I firmly grasp all of the information I am teaching in my AP psychology class…and I’ve been teaching it for six years. I still vividly remember my first year, only being one day ahead of the class, spending many early morning hours going over the material in hopes of avoiding looking ignorant in front of my students. Scary times.
Now, back to my original scenario. While my students continue to ask me the same questions about the same material, I stay calm. I proceed through a few steps:
- Try giving different examples.
- Ask another student to explain their understanding to the confused student as I listen for correctness. Sometimes, peers can offer up an example that better relates or explains the term/concept.
- Ask for the confused student to explain what they do understand about the term/concept. From there, I can pick up with an explanation. Usually, once I can pinpoint where their misunderstanding begins, I can proceed with more specific help.
Knowing that I am prone to experiencing the curse of knowledge actually helps me avoid it. I can remain calm instead of frustrated and continue to instruct my students; giving them the knowledge they need to mature their schemas and grow their understanding.
Have you ever experienced the curse of knowledge in your classroom?
How can knowledge of the curse of knowledge better your classroom?
