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.

Conducting Focus Groups With College Students: Strategies To Ensure Success, Felice D. Billups
Research Methodology
Institutional researchers are often asked to conduct focus groups as an efficient way to address an institutional concern or problem. Typically, IR professionals depend on external consultants and specialists to conduct these group interviews for them; however, due to recent resource constraints (staffing, budgets), they are increasingly assuming responsibility for conducting the focus group sessions themselves. Institutional researchers require specialized skills in order to engage college students in this type of group interviewing; college students present specific characteristics and preferences that require careful consideration. Numerous research studies have used focus groups to support or augment research on college students (Breen, …
