All rights reserved. In September, we began by using activities from the FOSS Variables kit. We spent about a month on this, and I became rather impatient to begin working with the investigation kits I had created. So in October, we launched the kits. The students were engaged, for the most part, but after a number of sessions, they proved unable to resolve their activities into bona fide investigations.
