I joined the VPA project because I believe in the idea of making assessment fun, or at least not anxiety provoking. Assessments help us understand how our students are processing information, but poorly designed assessments can be worse than no assessment at all. How do you measure science inquiry today? If you use paper and pencil, do you feel the the measurement gives you good formative information?
VPA is revolutionary in that students are truly investigating a scientific problem and gathering evidence to form a claim. When I watch students take the test, many are fully engaged and just a few a "playing" the game. However, either way I fee I am understanding how my students think through scientific problems in an authentic environment that can not be replicated without VPA.
