A journey north of the city

The American Educational Research Association had the annual meeting in San Francisco last weekend drawing around 15,000 participants from around the world. I was accepted to present some research from the SWH project regarding the effect of the implementation quality of the SWH on student performance. The presentation went well with roughly 75 people attending the session at 8am on sunday morning. There was quite a bit of interest in the topic and methodology after presentation.

The SWH team had four presentations displaying many of the good results we have been seeing due to the inquiry based approach to teaching science that has been employed in all these elementary schools across Iowa. Marcia was presenting results regarding increases in critical thinking and a couple of Brian Hand’s post docs also had presentations.

We had a perfect bluebird day on Saturday up at Snowbird and an off and on day up at Park City on Sunday.…

The Freezing Rain Sidewalk Challenge

01/27/2013 at 5:38 pm

Freezing rain occurs almost every year here in Iowa. However it isn’t every year that the sidewalks and roads completely ice over. This is both entertaining and dangerous to attempt to walk up a sidewalk with any significant slope. Unfortunately the longest sloped paths I knew of were not icy enough, but we found some formidable sidewalks that were nearly unwalkable. The following video highlights Our attempts to walk the sidewalks near our apartment.
