Developing Preservice Teacher Knowledge and Confidence of Functional Assessment-Based Interventions

This study examined early childhood special education preservice teachers' perceived knowledge and confidence, as well as actual knowledge of functional assessment-based interventions pre- and postuniversity course participation. A quasi-experimental two-group pre- and posttest design was applied to examine (1) initial differences between two groups (by assigned instructor) in preservice teachers' perceived knowledge, perceived confidence, and actual knowledge, (2) growth over time on these three measures, and (3) their concluding performance following course completion. Results indicated mean score differences between groups at the start of the functional assessment-based intervention course instruction. Large magnitude effects were found for both groups when comparing pre- to posttest scores of preservice teachers' ratings of their perceived knowledge and confidence, as well as a measure of actual content knowledge. Posttest scores showed preservice teachers ended the experience with similar levels of actual knowledge, regardless of group membership. Findings indicate preservice teachers may benefit from a preparation course with applied practice to develop knowledge and confidence for using functional assessment-based interventions, a promising practice (What Works Clearinghouse, 2016), to support students with challenging behaviors. Limitations and future directions are presented.
