In this article, the authors investigate if preservice teachers that experienced the CFSEP model in their science methods course and teaching practicum demonstrate stronger beliefs and practices in culturally responsive science pedagogy than a comparison group of preservice teachers. The participants were teacher candidates in the intervention group, who received a science methods course and teaching practicum experience that provided guidance in teaching science in culturally and linguistically responsive ways. The authors compare changes between a control group of preservice teachers and those involved in the intervention. The findings reveal that the intervention group increased more than the control group in their beliefs about the efficacy of this practice, which includes teacher’s use of purposeful grouping and sharing authority with students during science investigations.
