Description

This summary of project evaluation findings was presented to the InTERSECT team and DCPS leaders in February 2023 as a supplement to the Year 2 Summative Evaluation Report. The evaluation examined effects of Project InTERSECT on Cohorts 1 and 2, including student mathematics achievement and teacher perceptions. The project has had significant impacts on students’ mathematics achievement. Compared to a business-as-usual group (which was matched to the treatment group based on pretest scores, demographics, and grade level), students in Project InTERSECT classrooms performed significantly higher on iReady Math assessments. Treatment effects were particularly large for kindergarten (Hedges’ g = .34) and first grade students (g = .21). InTERSECT also impacted teachers’ perceptions. Compared to business-as-usual teachers, participants’ efficacy for teaching STEM was significantly higher, with large effects evident in efficacy for teaching Computational Thinking (g = 1.11), Math (g = .91), and Science (g = .63). Participation in InTERSECT also predicted teachers’ leadership beliefs (g = .48); perceptions of the quality and relevance of PD (g = 1.02), collaboration/coaching (g = .79), and feedback (g = .96). In general, findings are consistent across the Teacher Leader and PD pathways, suggesting the effectiveness of both teacher dosages in promoting improvements in teacher perceptions and student performance.
