Beyond This Place There Be Dragons

In A Private Universe, Heather’s challenges come from a number of places:

  1. Her brain’s attempt to integrate correct information from differing topics (see: Heather’s reference to analemmas in her description of orbits)
  2. Integrating learned conceptual knowledge with observed phenomena (seasonal differences caused by proximity to the sun makes sense when we think about our experience with proximity to a heat source)
  3. Her own best guesses at information she has not yet learned.

Heather’s misconceptions tend to be around phenomena she can’t observe.  As Driver et al (1985) states, “some elements in the structure of a scientific theory do not correspond to direct perceptions” (p. 5).  Because of this, Heather must assimilate knowledge of her perceived environment with the theoretical or unobservable.  The demonstrations her teacher led with the model of the solar system were helping to correct her understanding.  Posner et al (1982) theorized that to change a misconception, a person must: be dissatisfied with current conceptions, have the ability to understand a new conception, have an initially plausible new conception, and the new conception must be seen as means to open up new learning.    Heather’s old thoughts had a stickiness to them – whenever Heather was questioned beyond a point of her comfort zone, she would return to her old explanations.  When it came to her description of the seasons, it sounded like she was on the right track, but misconceptions revealed themselves when she was questioned.  Chi (2005) would point out that Heather was mis-categorizing an ‘emergent’ process as a ‘direct’ process.  Her ideas of direct and indirect light seemed to be based on her observed notions of reflection.  The observed direct process was so powerful in her thinking that she was able to ignore the fact there is almost nothing in space for the sun’s light to reflect off to ‘bounce’ back at Earth.

As a teacher, I remain an optimist about my student’s ability to adapt to new ways of thinking.  For Heather, I hope that, as she integrates correct information into her understanding, it will replace misconceptions.  It seems to me that the deeper her inquiry and the more frequent her exposure to the correct information, the more likely Heather is to rewire her brain away from the misconceptions she holds (though maybe that is my own deeply held misconception!).  While I was watching the video and listening to all the Harvard grads explain their flawed view of the changing seasons, I found myself shaking my head and feeling quite smug.  Later, I reflected on Heather’s interview and remembered how her improved explanations fell to pieces when she was questioned and probed deeper.  As an experiment, I began asking myself deeper questions about my own understanding of the seasons, and found it didn’t take long until I was out of my depth.  The fact is, there is a point at which every person’s understanding on a given topic comes to its limit.  Like the signs on ancient maps, ‘beyond this place there be dragons’, it is imagination, educated guesses, and misconceptions that live in that place beyond our understanding.

  1. Josh,
    Thank you for the engaging subject header line! There are a number of key points raised in your post. I’ll focus on a few for the class:

    1. “Heather’s misconceptions tend to be around phenomena she can’t observe”. Yes, when we can’t observe something or “see it in real life” we must rely in part on resources (our own cognitive resources and others). What implications does this have for promoting understanding in math and in science in our classrooms?
    2. “Heather’s old thoughts had a stickiness to them – whenever Heather was questioned beyond a point of her comfort zone, she would return to her old explanations.” Partial, incomplete, alternative, pre- or mis-conceptions have staying power. The spiral curriculum in science and math was supposed to address this, but as we see of the Harvard graduates who have taken courses, some whom have taken courses in astrophysics, and others who have “gotten pretty far,” student conceptions about the way the world works are fairly robust. The deeper questioning, as you noted, is a key instructional strategy. It also underscores how vital teaching is to math and science understanding. What are your thoughts on the structure of the new BC curricular changes for science and math? Are concepts revisited? What strategies are promoted?
    3. Mickey Chi’s work is a seminal piece on conceptual understanding. We met a few months ago at Purdue and discussed her ideas on expertise. Her work suggests that students place concepts in incorrect ontological categories and that these need to be addressed first. An example: heat is a “thing” versus a “process”. Her paper is well worth the read; I’m glad you took it up here Joshua.
    Thank you, Samia

  2. Hi Josh!

    I too share the same feeling that while I was shocked at the Harvard graduates and the similarity of their responses to grade 9 students, I began to wonder how much exactly do I know about the phases of the moon. I was struck with a blank mind as I couldn’t recall any information, let alone misconceptions. So like any self-respecting adult, I hunted down videos on youtube explaining the phases of the moon to balance the disequilibrium in my brain. So to your point, it is definitely true there is a limit to the depth of all knowledge that we can possess as individuals.

    Great post, thanks for sharing!
