Using Rasch Residuals To Analyze The Demographic Characteristics Of Respondents With Unexpected Incorrect Answers: Implications For Construct Validity, Robert K. Gable, Larry Ludlow, Ph.D., Stacey L. Kite
Research Methodology
This paper illustrates the use of Rasch model residuals to better understand perceived respondent meaning and structure of item content in the context of construct validity. Data were gathered from1366 grade 7-8 students using the Survey of Knowledge of Internet Risk and Internet Behavior. The characteristics of the respondents with unexpected patterns of residuals for persons not fitting the Rasch model are examined for 7 items defining the Knowledge of Internet Risk scale. These analyses contribute to a better understanding of the item content and person scores, and contribute to more meaningful score inferences.

A two-phase, sequential mixed-methods design was used to assess perceptions of teacher efficacy (10 item survey, alpha = .90) to differentiate instruction for N = 36 graduates from one MAT teacher preparation program.

Data were analyzed using descriptive statistics, one-way ANOVA and t-test procedures. A focus group with N = 10 purposively selected 2010 graduates and interviews with N = 2 graduates each from the 2008 and 2009 classes, and N = 2 faculty were conducted. No significant relationships were found for tenure and …
