Quasi-experimental research designs therefore use alternative ways of assigning subjects to the treatment and control groups. The most common subset of quasi-experimental research designs are the nonequivalent control group designs. In one implementation of this design, subjects in the control group are intentionally matched by the researcher .pdf version of this page The basic idea of experimental design involves formulating a question and hypothesis, testing the question, and analyzing data. Though the research designs available to educational researchers vary considerably, the experimental design provides a basic model for comparison as we learn new designs and techniques for conducting research.

Over the past couple of decades, teacher effectiveness has become a major focus to improve students’ mathematics learning. Teacher professional development (PD), in particular, has been at the center of efforts aimed at improving teaching practice and the mathematics learning of students. However, empirical evidence for the effectiveness of PD for improving student achievement is mixed and of quasi-experimental research design. In this chapter, we separate the content into two major sections: quasi-experimental designs and single-case experimental designs.
