An ABAB reversal design was utilized to examine the effects of an electronic daily behavior report card (eDBRC) on non-compliant, off-task, and disruptive classroom behaviors of a 16-year-old with autism spectrum disorder and a 17-year-old with an intellectual disability. The intervention was implemented by two preservice teachers (interventionists) in their final student teaching requirement. In addition to visual analysis procedures, effect sizes (i.e., Tau-U) were calculated. The research questions were: (1) What are the effects of eDBRCs on participants’ disruptive and challenging classroom behaviors, (2) To what extent do preservice teachers implement eDBRCs with fidelity, and (3) Are eDBRCs a socially valid intervention? Upon completion of our study the eDBRC was effective in reducing non-compliant, off-task, and disruptive behaviors. We found that preservice special educators can implement a complex behavior intervention to support the outcomes of their learners during the student teaching experience. Additionally, we suggest eDBRCs are an acceptable intervention for students with autism spectrum disorder and intellectual disabilities.

Each year, more teachers learn about the successful intervention program known as Math Recovery (USMRC 2008; Wright 2003). The program uses Steffe's whole-number schemes to model, understand, and support children's development of whole-number reasoning. Readers are probably less familiar with Steffe's fraction schemes, which have proven similarly useful in supporting children's development of fractional reasoning. The purpose of this article is to introduce some of these schemes. We provide examples of student work accompanied by discussions of how fraction schemes can be used as tools for insight into student reasoning. We hope that teachers will find the schemes useful in understanding their students as mathematicians.
