This application is designed to generate estimates of expected effect sizes based on known intervention or study characteristics. These estimates can be used by researchers in the study planning stage (i.e., in a priori power analyses) or by decision-makers to inform programmatic decisions in science education. For details of the study upon which this calculator is based, please see Taylor, Kowalski, Polanin, Askinas, Stuhlsatz, Wilson, Tipton, and Wilson (2018). BSCS received substantial assistance in the design of the calculator from Zhipeng Hou, Northwestern University.
