In this course, students are introduced to the methods needed to evaluate the effectiveness of a variety of interventions. Students learn to develop reliable procedures for measuring behavior using both continuous and discontinuous measurement systems, effective methods to display data, and develop skills to analyze the visual representation of behavior change in a variety of graphic displays. This course places a particular emphasis on the use of single-subject designs, which include the reversal, alternating treatment/multi-element, multiple baseline, changing criterion, and concurrent chains arrangement. By the end of this course, students will be able to select an appropriate measurement system, calculate reliability measures, identify the most appropriate experimental design(s), and determine whether functional control was achieved.
