Course Description

Single subject design methodology has developed primarily within the
field of behavior analysis but has wider application beyond that
theoretical orientation.  It represents an intervention-oriented
methodology that is idiographic in nature, requires frequent
measurement of the dependent variable, and employs replications
within and across participants.  In addition, single subject design
studies frequently use direct observational methodology as the
dependent variable.  In this course, we will begin with an overview
of single subject design research methods and their application
within special education.  We will next examine methods of behavioral
assessment and techniques for conducting observational research.  A
variety of single subject research designs will be examined, with the
strengths and weakness of each identified.  Issues related to
treatment fidelity, social validity, and ethical use of single
subject research methodology will be discussed.

Structure of Course

The format of this course will include both lecture and seminar
sessions.  Students must complete all the assigned readings for each
session in order to participate in the seminar portions of class each
week.  Also, students will develop a single subject design research
proposal that addresses the research question(s) of their


By the end of this course, students will have a working knowledge of:

1.  Threats to internal and external validity of single subject

2.  Current dimensions of behavior analysis

3.  Strategies for assessing social validity

4.  The process for identifying research questions in single subject
design research

5.  Strategies for identifying target behaviors

6.  Requirements for establishing an operational definition

7.  Requirements for determining sample size in observational research

8.  Techniques for training observers

9.  Methods for assessing interobserver agreement

10.  Methods for assessing interobserver accuracy

11.  Computer and other technological aides for collecting
observational research

12.  The role of replication in single subject design research

13.  Reversal and withdrawal of treatment designs

14.  Multiple baseline designs and their variations

15.  Designs that compare treatment effects

16.  Procedure for reviewing journal manuscripts
