MoDa

MoDa is a web-based environment that juxtaposes computational modeling side by side with real-world data for comparison and validation. The environment includes a modeling area and a real-world data area. The environment consists of:

1. A Coding workspace where learners program their models using a library of domain-specific blocks (Wilkerson, Wagh & Wilensky, 2015). This is a custom block-based coding tool built on Google’s Blockly library;
2. A Simulation workspace where students can run and manipulate the model they built in the coding workspace. Models are generated using the NetLogo engine (Wilensky, 1999); and,
3. A Model Data Visualization area that displays plots for selected data generated by the model in real time.
