1. Single Subject Design

2. Agenda Finish Group Analysis Article Review Survey Issues
Introduction to Single Subject

3. Types Longitudinal of Survey Studies
Trend
Changes over time
e.g., gallop poll
Cohort
Common defining characteristics
e.g., 3rd grade students in 2007, may or may not be the same group in the 5th grade in 2009
Panel
Same people over time
LBSI students at practicum, student teaching, 1 year after first job

4. Devising your own Survey is Tricky!
Clear terminology and wording
Points to the studies questions
Eliminate vague questions
Anchor ratings
Pilot your instrument

6. Functional Relationships????

7. Establishing Cause and Effect
Single subject design is can establish cause and effect
It does this by demonstrating that repeated applications of interventions, under controlled conditions, allows us to make an inference about the connection between the independent variable and the dependent variable
Different patterns and types of designs help us establish the “functional relationship”

8. Baseline Terminology and Comprehension
What is it?
Why is it important?
What do we need to know?
Baseline
Predictive Function
Trend
Decreasing Baseline
Increasing Baseline
How do I compute baseline stability and what is it?

9. Explain the Design AB Design & Changing Criteria Reversal Design
Alternating Treatments Design
Multiple Baseline
Define/Purpose
Limitations and Strengths
Graph and explain an example use based on a hypothetical experiment
