Over at Reason and Wonder, Michael Fenton is exploring the possibilities for using Alex Gendler video puzzles in the classroom. Michael’s wonderful take on these rich resources, reminded me of one of the main goals of this blog, to show how students with disabilities can access rich mathematics instruction.
As we began this school year, my goal was to model how our class valued perseverance and sense-making over answer-getting. I did this for a couple of my classes by using Gendler’s Zombie Bridge Problem video. The video is long and there are a lot of details to account for before you can come to a reasonable solution. This requires quite a bit of what is called executive functioning. Executive functioning includes (but is not limited to) the abilities to initiate a task, make a plan, prioritize information, organize information, think flexibly about strategies, and self-monitor (i.e. check your work). Sound familiar? My students tend to struggle with executive functioning skills and this is often where my scaffolding is targeted.
To help scaffold my student’s executive functioning while solving the Zombie Bridge Problem, I used EDpuzzle. EDpuzzle allows a teacher to modify an already existing youtube or uploaded video by cropping it, including voiceovers and adding questions. Here is how I used EDpuzzle to scaffold the Zombie Bridge Problem.
First, I cropped the video to exclude the solution. As anyone familiar with 3-acts knows, the solution is vital, but should come after students have had time to explore first! So it was gone.
Several months ago, the new NPR show Invisibilia did a broadcast about expectations. The main theme of the program was that the expectations others hold of an individual can effect the outcomes of that individual, either positively or negatively. If you’d like to know more about this idea please listen to the radio show, its great!
I wanted to incorporate the show’s theme into a blog post about special education math classes, but was unsure how until Alex Overwijk, a teacher from Ottawa, sent me the following comment about my post about scaffolding…
This led me to consider how the over-scaffolding of mathematical tasks and problems for special education students creates an atmosphere of lowered expectations. Both Alex and I agreed that students with disabilities need a certain amount of scaffolding to be successful. What we didn’t know was to what degree and when this scaffolding should be provided.
Thinking more deeply about this question, I believe the degree to which scaffolding is provided to students with disabilities is a very individual, personalized process. Great special ed teachers who understand their student’s learning pathways will be able to determine the appropriate level of scaffolding for them. But the timing of when scaffolding is provided can show students what a teacher’s expectations are for them in math class. If scaffolding is implemented too early in a lesson or unit, students may feel a sense of lowered expectations which according to Invisibilia would result in lowered outcomes as well. You can’t get much earlier in a lesson or unit than the pre-assessment, so let’s start there.
