Our earliest work as education evaluators was 1999 in support of the UMass Amherst On Line homework system (OWL) in chemistry, physics, math, computer science and art history. Since then we have supported almost 50 innovative curricula projects across STEM disciplines at 20 higher education institutions and corporations (non-profit and private). Our approach is to look at both the efficacy of the innovation on the students, and also to understand and document associated changes in pedagogy and institutional impact.
