Historically, the synthesis of single subject design has employed visual inspection to yield significance of results. However, current research is supporting different techniques that will facilitate the interpretation of these intervention outcomes. These methods can provide more reliable data than employing visual inspection in isolation. This…

The primary research problem confronting many experimental researchers is finding valid stimulus (instructional) and criterial (testing) materials that operationally fit their hypotheses. Five experimental studies have been completed, and two are in progress, using the Dwyer instructional materials to address the problem of finding valid…
