Item response theory (IRT) is currently the dominant methodological paradigm in educational and psychological measurement. IRT models are based on assumptions about the relationship between latent traits and observed responses, so the accuracy of the methodology depends heavily on the reasonableness of these assumptions. This dissertation consists…

This qualitative case study explores the story of celebration for kindergarten teachers at a suburban elementary school in northern New England. This study explored the reality of self-celebration in kindergarten teachers' current practices during staff meetings, planning meetings, response to intervention (RTI) meetings, with their colleagues,…

My dissertation research explored responder behaviors (e.g., demonstrating response styles, carelessness, and possessing misconceptions) that compromise psychometric quality and impact the interpretation and use of assessment results. Identifying these behaviors can help researchers understand and minimize their potentially construct-irrelevant…

This study addressed researchers call for collecting the perceptions of how Texas Teacher Evaluation and Support System implementation and feedback affect prekindergarten teachers' instructional practices and the alignment of the T-TESS instrument to the Texas prekindergarten guidelines because the focus of such research is usually on teachers of…

This dissertation study investigated how L2 doctoral students regulate their emotions upon receiving written feedback from their mentors. The study took a multiple-case-study approach that entailed stimulated recall of the feedback-reading and revision process. Three international doctoral students who were engaged in high-stakes writing in the…

This dissertation presents a comprehensive review of the evolution of DIF analysis within educational measurement from the 1980s to the present. The review elucidates the concept of DIF, particularly emphasizing the crucial role of grouping for exhibiting DIF. Then, the dissertation introduces an innovative modification to the newly developed…

In this portfolio, I reflect on my efforts to provide professional development targeted to support teachers during the launch phase of their mathematics teaching, to elicit and respond to student ideas and experiences. I grounded my study in research on ambitious teaching practices for launching complex mathematical tasks using problem-based…

While the number of autistic students attending college has increased, research in this area has only recently gained momentum. Research on faculty interactions and relationships with autistic students is particularly limited. In this qualitative study, I conducted semi-structured interviews with 15 faculty to explore how they interacted with and…

The goal of this study is to evaluate the effectiveness of the RTI process and its impact on student achievement. Data analysis will be used to identify areas of strength and weakness in the current system and provide insights into how to create a more effective RTI program. The findings from this study will be used to inform future…

Six experiments were conducted with graduate students to assess resurgence of compound (i.e., multi-step) academic responding under free operant procedures. Participants learned two different interobserver agreement (IOA) methods -- compound behaviors -- through instructional phases before beginning the experimental phases. Each experiment…

Math anxiety impedes people from working to their fullest potential (Hyman et al., 2015; Retanel et al., 2021) and impacts people of all ages, including both children and adults (Oh et al., 2022; SzczygieL, 2020). The influence parents' math anxiety has on children is also impactful on the children's own development of math anxiety or negative…

Despite studies showing that individuals with higher levels of emotional intelligence report higher job satisfaction and happiness, relatively few studies have looked at the relationship between higher levels of emotional intelligence and lower levels of teacher burnout, especially among music teachers. With so many music teaching positions going…

Response style, one common aberrancy in non-cognitive assessments in psychological fields, is problematic in terms of inaccurate estimation of item and person parameters, which leads to serious reliability, validity, and fairness issues (Baumgartner & Steenkamp, 2001; Bolt & Johnson, 2009; Bolt & Newton, 2011). Response style refers to…

Multidimensional Item Response Theory (MIRT) has been widely used in educational and psychological assessments. It estimates multiple constructs simultaneously and models the correlations among latent constructs. While it provides more accurate results, the unidimensional IRT model is still dominant in real applications. One major reason is that…

In identifying ways to create inclusive spaces in the classroom, instructors should not be limited by singular modes of discourse to engage students. Particularly when teaching first-year students who seek to invent the university and claim their intellectual space within it, these considerations must be deeply integrated into the course…
