Assessing Fidelity of Implementation of an Instructional Model: Targeting Student Trajectories Toward Biliteracy

• In Event: Perspectives on Biliteracy Research

Abstract

This study examines the degree that student outcomes associated with a bilingual/biliterate instructional model vary as a function of teachers’ fidelity of implementation (FOI). We used principal components factor analysis with an oblique rotation to assess the dimensionality underlying the collection of FOI measures and created factor scores for each dimension represented in our final factor analytic model. Preliminary results suggest two dimensions underlying FOI measures collected. Subsequent models of student outcomes on standard normal, regression-method scores suggest effects associated with the FOI dimensions differ for different student outcomes. Findings inform the revision of FOI assessment measures and improve professional development targeting program implementation. Detailed attention to FOI is critical to valid assessment of proposed educational innovations for bilingual students.
