The Effects of Hybrid Algebra I on Teaching Practices, Classroom Quality, and Adolescent LearningThe Effects of Hybrid Algebra I on Teaching Practices, Classroom Quality, and Adolescent Learning

Key outcomes and measures

The primary measures of the intervention's impact on student outcomes are designed to capture both the immediate impact on student achievement in algebra I and longer term effects on achievement and educational attainment. Outcome measures include an end-of-course test in algebraic understanding administered by trained site researchers in late spring of the intervention year, as well as the math portion of the PLAN® test—given to all Kentucky students in the fall of grade 10. The researchers use administrative records for intervention-year students from the Kentucky Department of Education to construct their enrollment rates in higher level math courses as well as high school continuation rates, in the postintervention school year. End-of-course tests are also given to assess the algebra I achievement of grade 9 students in the second year group in treatment and control schools. This assessment, given in the postintervention school year, provides an estimate of the longer term impact of the intervention on teaching effectiveness measured in terms of student achievement.
