Computing has become an integral part of the practice of modern science, math, and engineering. In addition, contemporary STEM careers and research show increased emphasis in the workforce on the need to understand, and to be able to use computing and have computational thinking skills. Moreover, the National Research Council Framework for K-12 Science Education (NRC, 2012) outlined important epistemic practices of science regarding computing that was intended to guide STEM instruction. However, for a myriad of reasons, institutions like K-12 education have not kept up-to-date with integrating the necessary skills development needed for STEM careers. Further, K-12 teachers need assistance in developing and using effective, evidence-based practices for integrating computing and/or computer science into their STEM practice, such as modeling, data analysis, systems and computational thinking.
