QuantitativeQuasi-Experimental Designs
This family of research designs is characterized
by non-random selection of subjects. The
following experimental designs are based on the
problem statement The effects of teaching
method(s) on history achievement.

Question Does exposure over a period of time have
a lasting effect?

Time Series Design (example)
Hypothesis The use of a History Channel? video
as a teaching strategy will result in long-term
retention of history knowledge.

Quasi-Experimental Single SubjectA-B Design
Single Subject methodology makes use of two
conditions. The Baseline condition A and the
Experimental Treatment condition B and focuses
on the behavior of an individual.

Quasi-Experimental Single Subject/Multiple
BaselineA-B-A-B Design
The Multiple Baseline design allows one to study
multiple effects make multiple comparisons over
time.
