We have wanted for some time to gauge classroom usage of the evolution poster, so last month Brights Central sent out a survey to the high school science teachers who had been recipients last year (324). We are gratified to have achieved a 24.5% response rate. Of course, some teachers were unreachable (no longer at same school, changed email addresses, etc.) and so there was a fair level of email bounces along with reports of changed teaching circumstance (9.6%).
Overall, the reported usage is heartening. Many teachers told of having integrated the poster into their instruction for a surprisingly long time (16.5 days on average!), with the most commonly reported single value being 5 school days of actual usage in instruction. The poster stayed on classroom display a far longer duration, with 63% reporting more than 2 months (doubtless some were perhaps all year, although that wasn’t a choice we offered), with 12% for 1-2 months, 8% for 2-4 weeks, and 10% 1-2 weeks. Five percent apparently did not use it, despite the commitment.
Most gratifying is how many teachers want to use the poster this coming year! Although 9.4% do not plan to use it this year and four percent will "use it, but less", those teachers who chose “as much as previously” (64%) and “more than before” (23%) combine to yield a heightened level of usage overall. This result (87%) is a superb indicator of instructional worth, even in the face of possibly changed teaching circumstances.
