Teaching at D.Tech High School: Chemistry (Part 3)

I enter the classroom after Greg Fenner has begun the lesson. Thirty-one students sit at eight scattered tables in a large room adorned with the essential Periodic Table of Elements. A cart filled with tablets sits at one side of the room. Each table seats four students comprising a team for activities and homework that the teacher assigns during a lesson.
Sporting a trim beard and mustache, Fenner wears jeans, blue T-shirt and tan desert boots. He also has a cloth shoulder strap holding a small pouch.  Perched on his head is a pair of goggles. A graduate of a Bay area university’s teacher education program, this is Fenner’s fourth year at d.tech. He lives in San Francisco and often bikes to the city train station, rides to a stop a few miles away from d.tech high school and completes the commute on his bike.
Today is lab day.  Students will be studying chemical reactions using hydrochloric acid and baking soda. They follow instructions in their textbook, Chemistry in the Earth System, a text linked to Next Generation of Science Standards adopted by California.

Lab workbook exercise
A table near where I am sitting holds eight lab trays filled with a thermometer, flask, measuring cylinder, filter paper, beaker, and one pair of goggles. Fenner explains what the strength of the acid is and the importance of being careful when using it in the experiment. He explains students will mix it with sodium hydrogen carbonate (baking soda). He gives safety instructions to the class before one student from each team comes up to get a tray to bring back to the CONTINUE READING: Teaching at D.Tech High School: Chemistry (Part 3) | Larry Cuban on School Reform and Classroom Practice
