Both of these articles discussed the idea of choosing
anchoring events and having students create explanatory models that connect
many different ideas from the particular unit being covered. The articles argue
that these anchoring events help students narrow down why they are studying
science, create overarching meaning, and connect a number of scientific theory,
principles, and ideas.
If I am
being completely honest, I don’t love this idea. I felt that a lot of the
examples presented in the book could be searched on Google and found relatively
easily, especially with the format that these articles suggest using. I know
that personally, my kids hate being wrong and they love their iPads. If I
presented a question like this and asked to create an explanation, their knee
jerk reaction would be to ask if this particular assignment is being graded on
accuracy. And as soon as you tell a student that it is for participation grade,
often I feel that the rigor and the cognitive awareness decreases
significantly. Their second question
would be “can we use our iPads?” because creating an explanation for something
you know little to nothing about can be very daunting and overwhelming.
I also feel
like there is a lot of guesswork and unknowns for students, especially at the
beginning. Is there a way to take this uncertainty away from students and
provide a little bit more support? I like the explanatory model and I agree
that it is something that we as scientists do often. However, we typically make
explanatory models when we have more information and have done relatively vast
amounts of research. We hardly ever observe something and make a full blown
explanation. Would this still be beneficial to do in the middle of the unit
once students have a little bit more information or would that put the
cognitive load on teachers instead of students?
I would
love to see what a rubric for assignments like these look like as well as
discuss how to keep motivation high. Currently
I feel like if I did this with my kids I would just be throwing them in the
deep end with little support. I think this could work I just feel like the way
these articles describe it, students are given little support past a few
ambiguous guiding questions and guidelines concerning how students will set up
their drawings.
I also
didn’t love how the article knocked students replicating models of “things.” As
someone who teaches chemistry and deals with concepts that students can’t see
and if they do not build models they flat out will not understand. You cannot
present the atom to kids without having them build a model. They don’t know
what these things look like and the best way for them to get an idea is to see
it, touch it, and build it.
While I
agree that students should be given assignments that are relevant and
purposeful and connect many different ideas, I think that there could be other,
better ways to do it. I think that this could work however, if students had
more support and possibly a rubric detailing what students are supposed to do.
I really enjoyed reading your review and opinion of the articles. I completely agree with you about having to have replica models of atoms in a chemistry class. They also said that online simulations don't work well in the classroom, but my students seem to really enjoy them, and I think it helps them better understand certain topics, like bonding and VSEPR. I think all of the ideas sound great in reading, but in reality there are more challenges that weren't necessarily addressed in the articles.
ReplyDeleteI understand your frustrations, and I wonder how you can integrate the two? Maybe you could present students with the ability to research or view models within the context of a larger unit that has an anchoring event and they use explanatory models throughout the course of the unit. They could incorporate the given models into their own explanations. I think students would need to practice the process for it to work. I definitely agree that a rubric would help support students as they learn the process.
ReplyDeleteI really appreciate your honesty in expressing your frustration and disagreements with these readings. I think your emphasis on the importance of scaffolding is spot on. These types of models could potentially be worked up to but, if jumped straight into, could definitely intimidate students. I wonder how you could use your class culture to help create an environment in which the students feel more comfortable venturing guesses even before they have all of the information. Could you, perhaps, start with having students critique and correct existing models before moving towards creating their own?
