1 A collaboration between Maryland Virtual High School and the Pittsburgh Supercomputing Center

2 Participants will gain A working definition of computational reasoning by using simulations to collect and analyze data, test hypotheses, and illustrate scientific concepts. A basic understanding of the capabilities of a variety of computational tools. Insight into the ways in which computational reasoning can be infused in their teaching.

3 Three Facets of Computational Reasoning Meeting the Pennsylvania Standards d Coin-flipping and Forest Fires Fractions and the Water Cycle A Smorgasbord of Resources Next Steps

4 Understanding di how to analyze, visualize and represent data using mathematical and computational tools Using computer models to support theory and experimentation in scientific inquiry Using models and simulations as interactive tools for understanding complex scientific concepts
