Imagine being 12 years old and being told that you’re made up of tiny bits, that are made up of tiny bits, that are made up of tiny bits; and all those bits are going to interact in different ways and have AWESOME names that sound more like spells from Harry Potter than English. For me, teaching cell transportation at the middle school level has been a challenge.
When students walk into our classrooms many of them have no concept of cells other than the ones they’re carrying in their pockets. We, as science teachers, have long relied on analogies to demonstrate concepts; although this method has worked, I find there’s always a student who is confused by the “endoplasmic reticu-what” and cannot work their way up Bloom’s or grasp the Depth of Knowledge (DOK) I’m seeking for mastery,
This fall, I decided to change my approach when teaching the topic of cells. Instead of having my students dance out the process of endocytosis (think the hokey pokey: “things move into the cell, things move out of the cell… and they move all about”), I would try to align more to NGSS using an approach rooted in phenomena.
