Coding as Another Language (CAL) curriculum
About the Intervention
Coding as Another Language (CAL) is a curriculum developed by Boston College's DevTech Research Group that integrates coding and computational thinking with literacy skills for kindergarten, first, and second grade students. The curriculum uses the ScratchJr app and consists of 24 lessons of 45 minutes each, delivered in-person to whole classes during regular school hours. CAL introduces coding in a playful, developmentally appropriate way by integrating powerful ideas of computer science with literacy and math skills through both unplugged activities and on-screen coding. Before implementation, teachers attend two 2-hour professional development workshops (4 hours total) and complete their own ScratchJr project. Teachers also have access to onsite and virtual coaching support during implementation.
