Reflection: Checks for Understanding Inside Information Part 2 - Section 2: Activity Day 1- Reflex Action


When I was first teaching this lesson, I was not sure why the authors included the Building a Reflex/Voluntary Pathway and the Pathway-Building Worksheet.  It seemed to me that one would be sufficient but never having gone through this lesson before I decided to include both and now I am glad that I did.

I had my students complete the Building a Reflex/Voluntary Pathway pages using color for the drawings and include a color code key, which normally I would think was sufficient.  This is a nice resource for students to have when they need a quick reference to how the nervous system functions in regard to reflexive and voluntary actions.  However, as I read through the written responses on the Pathway-Building Worksheet, I found a need to have a quick discussion on the importance of the brain and spinal column in regard to their role of interpreting the information.  For some reason, many of the students' answers discussed the different neurons involved but they failed to mention that the brain/spinal column also play critical roles.  

After a quick discussion as a class, it was clear that some students were unclear as to the role of the spinal column during a reflex action (the brain they knew but forgot to include because it was "obvious", got to love that teenage reasoning!)  Without the written portion of the formative assessment, this lack of clarity would have gone unnoticed.

Inside Information Part 2

Unit 4: Information Processing
Lesson 7 of 11

Objective: SWBAT explain how the pathway of reflex actions and voluntary actions differ.

Big Idea: Students use a simple computer model to determine how information travels in both reflexive and voluntary motor responses.
