    This tech demo introduces key enhancements to MoDa: A free, open-source web based modeling and data analysis system designed to support students in making sense of complex systems. MoDa is a domain-specific, block-based computational modeling tool that allows students to build models side-by-side to real-world data. Our latest enhancements include integrating quantitative data in the system using the Common Online Data Analysis Platform and Activity Player to support structured data-rich investigations, allowing students to use a wider variety of real-world data sources to refine their model toward reproducing important features of system behavior both qualitatively, by reproducing important visual and dynamic behaviors, and quantitatively by allowing closer comparison of patterns, relationships, and variability.

    Rivulet is a framework and collection of Python Jupyter notebooks for fetching pedagogically generative scientific datasets. They provide executable templates for accessing, filtering, and evaluating data from public databases using Application Programming Interfaces (APIs) and expert insights regarding quantitative features of scientific interest. Our primary goal is to support educators and curriculum designers finding data that support meaningful statistical and scientific engagement through relevance to both students and to the domain.
