Evaluation Designs for Practitioners. TM Report No. 35.
Eash, Maurice J.; And Others
Practitioners are not afforded the luxury of ideal laboratory conditions. The natural settings of the classroom, the school, or the school system place constraints on the type of data obtainable; hence, educators must work with less than an ideal experimental design. Four evaluation designs used in natural settings are described. Each involves an evaluation study that takes into account a variety of constraints, but nevertheless provides a basis for subsequent program and/or organizational decision. The study includes a true experimental design in a field setting, a nonequivalent control groups design, a time series design, and a no comparison groups design. (Author/RC)
