Reflection: Checks for Understanding A Day of Discovery (C how Elegant Model Organism Nervous Systems Are!) - Section 4: Explain/Extend


     In this section of the lesson I aimed to gain some insight into my students appreciation for C elegans as a viable model organism. Given the opportunity to both observe the worms' behaviors and read background on their physiology, I personally wanted to witness if students would grow in their responses to the overarching question: "Are C elegans ideal model organisms for human nervous system studies?" What I noticed is that in general students were convinced from their first round of observations that it was an ideal model, but had some difficulties articulating why (no specific biological basis). After reading the background information, which understandably yielded a detailed biological basis for the organism, students were even more convinced (See Student Sample #2 responses) to use the worms as model for human systems. Still, they were pretty generic in their articulations (See Student Samples) and this created a basis for me to enrich further discussions onward so that could solidify why we use model organisms in general.

A Day of Discovery (C how Elegant Model Organism Nervous Systems Are!)

Unit 11: The Brain and Toxins (Drugs and Environmental)
Lesson 1 of 8

Objective: Students will develop and use models to qualify C elegans as a model organism for human nervous system studies.

Big Idea: C elegans are ideal model organisms which provide researchers with insight to the repercussions of environmental agents that could potentially cause harm to the human nervous system.
