Development And Validation Of The Statistics Assessment Of Graduate Students, Dammika Lakmal Walpitage
Development And Validation Of The Statistics Assessment Of Graduate Students, Dammika Lakmal Walpitage
Doctoral Dissertations
This study developed the Statistics Assessment of Graduate Students (SAGS) instrument, and established its preliminary item characteristics, reliability, and validity evidence. Even though there are limited number of assessments available for measuring different aspects of statistical cognition, these previously available assessments have numerous limitations. The SAGS instrument was developed using Rasch modeling approach to create a new measure of statistical research methodology knowledge of graduate students in education and other behavioral and social sciences. Thirty-five multiple-choice questions were written with stems representing applied research situations and response options distinguishing between appropriate use of various statistical tests or procedures. A focus …
An Examination Of The Psychometric Properties Of The Student Risk Screening Scale For Internalizing And Externalizing Behaviors: An Item Response Theory Approach, Sara E. Moulton
Theses and Dissertations
This research study examined the psychometric properties of the Student Risk Screening Scale for Internalizing and Externalizing Behaviors (SRSS-IE) using Item Response Theory (IRT) methods among a sample of 2,122 middle school students. The SRSS-IE is a recently revised screening instrument aimed at identifying students who are potentially at risk for emotional and behavioral disorders (EBD). There are two studies included in this research. Study 1 utilized the Nominal Response and Generalized Partial Credit models of IRT to evaluate items from the SRSS-IE in terms of the degree to which the response options for each item functioned as intended by …
The Effects Of Scaling On Trends Of Development: Classical Test Theory And Item Response Theory, Weldon Z. Smith
The Effects Of Scaling On Trends Of Development: Classical Test Theory And Item Response Theory, Weldon Z. Smith
College of Education and Human Sciences: Dissertations, Theses, and Student Research
The scale metrics used in educational testing are often arbitrary, and this can impact interpretation of scores on measurements. Both classical test theory sum scores and item response theory estimates measure the same underlying dimension, but differences in the two scales may lead one to be more preferential than the other in interpreting data. Mismatch between individual ability and test difficulty can further result in difficulties in correctly interpreting trends of development in longitudinal data. A previous limited simulation by Embretson (2007) demonstrated that classical test theory sum scores result in misinterpretation of linear trends of development, and that item …
Longitudinal Analysis For Ordinal Data Through Multilevel And Item Response Modeling: Applications To Child Observation Record (Cor), Zijia Li
Theses and Dissertations--Educational, School, and Counseling Psychology
The large proportion of children from low SES backgrounds and the increasing achievement gap between disadvantaged children and their more advantaged peers are beckoning national attention to investment in early childhood education (Reid, Kagan, Hilton, & Potter, 2015). As evidenced in many research studies (e.g., Heckman & Masterov, 2007), early childhood experiences are critical to the development of children. High-quality early learning is necessary for children, especially disadvantaged children, to narrow the school readiness gap and to build a foundation for more advanced academic, social, and cognitive skills. Importantly, high quality assessment tools (i.e., reliability and validity evidence supporting the …
