Louisiana State University (LSU) received an Education Innovation and Research (EIR) grant to implement its Introduction to Computational Thinking (ICT) course from fall 2019 through spring 2023. ICT is a yearlong course that builds skills in problem solving, programming, and mathematics (algebra and geometry) and is intended to improve performance on Louisiana state math assessments. The course's goals are to improve understanding of mathematical concepts and computational thinking and increase engagement and interest in mathematics and computer sciences for students from all backgrounds. For this project, the ICT course was implemented in high schools in East Baton Rouge Parish (EBR); non-EBR high schools that are considered high need, many in rural areas; and non-EBR high schools that are considered low need, many in suburban areas. LSU contracted with Education Northwest to conduct the impact and implementation fidelity studies required of every EIR grant recipient. This report summarizes findings associated with the second year of implementation, which includes summer 2022 and the 2022-23 school year. The implementation fidelity study addresses three research questions: (1) Were the key components of the intervention implemented as planned? (2) How did implementation fidelity vary by school geographic area (urban, suburban, town, or rural) and level of need? and (3) What were facilitators of and barriers to implementation?
