Analyzing Clustered Longitudinal Data Using Latent Curve Model With Structured Residuals (Lcm-Sr), Dongho Choi
Analyzing Clustered Longitudinal Data Using Latent Curve Model With Structured Residuals (Lcm-Sr), Dongho Choi
College of Education and Human Sciences: Dissertations, Theses, and Student Research
The LCM-SR can provide an inferential basis for understanding reciprocal relations while controlling for individual differences in the trajectories of young children’s psychological development. Yet, a hierarchical structure in the data has not been often adequately addressed even though that is common in social and educational research. The purpose of this study is to explore the impact of dependency among observations on the results when using the LCM-SR, and how to appropriately analyze the clustered longitudinal data for more accurate inference. To do this, the MLCM-SR (disaggregated approach; the “two-level” model) was introduced and compared with the single level LCM-SR …
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 …
Effective Science Teachers’ Professional Development: A Multiple-Case Study Of District-Level Science Supervisors’ Perspectives, Chris J. Schaben
Effective Science Teachers’ Professional Development: A Multiple-Case Study Of District-Level Science Supervisors’ Perspectives, Chris J. Schaben
College of Education and Human Sciences: Dissertations, Theses, and Student Research
At its heart, science teachers’ professional development is about continual growth and improvement (Yager, 2005). Conducting research to understand what constitutes effective professional development is inherently complex (Hewson, 2007). The imperative to link research on professional development to student achievement (Fishman, Marx, Best, & Tal, 2003) increases complexity of research on the topic. These complexities require multiple research approaches and indicate that all stakeholders could provide insights to identify what constitutes effective professional development. District-level science supervisors’ voices are missing from the data on effective science teachers’ professional development and this provides a potential gap in the literature (Banilower, Heck, …
The Embodied Mind In Early Development: Sitting Postural Control And Visual Attention In Infants With Typical Development And Infants With Delays, Regina T. Harbourne
The Embodied Mind In Early Development: Sitting Postural Control And Visual Attention In Infants With Typical Development And Infants With Delays, Regina T. Harbourne
College of Education and Human Sciences: Dissertations, Theses, and Student Research
As infants learn to sit between the ages of 5 and 8 months, they undergo many changes in their bodies as well as in their minds, creating conditions for the emergence of skills that allow greater interaction with their environment. The present study focused on the interaction of developing postural control in sitting with cognition, exemplifying the concept of the embodied mind. Look time, or the time an infant looks at an object, served as a proxy for the construct of cognitive processing. Three experiments examined developmental changes in sitting postural control and looking. The first experiment examined archival data …
