Systems thinking is often referred to as "Bathtub Dynamics" (Meadows, 2008). A bathtub accumulates some amount of water that is filled via a faucet and empties via a drain. These two flows determine the level and stability of the water in the bathtub. "Dynamic equilibrium" occurs when the inflow and the outflow are equal. Our video visualizes this dynamic and shows how our "stock and flow" data tool is deeply linked to these principles.
basic model of learning
For those of us in the field of education, working in schools starts with a mental model of how students learn. That is, effective schools must be organized (or designed) around this fundamental concept. Effective systems (e.g. attendance, scheduling programming, academic interventions) reinforce the opportunities for student learning. Core school systems never operate independent of one another. A comprehensive attendance system will always reinforce instructional and academic intervention systems just as a weak attendance system will undermine them. Our systems thinking video highlights this interdependence.
And this next video highlights how the timing of assessments intersect with the basic model of learning. Poorly timed assessments have important implications for a student's ability to progress.
