Simulation studies are needed to investigate how many score categories are sufficient to treat ordered categorical data as continuous, particularly for bifactor models. The current simulation study aims to address such needs by investigating the performance of estimation methods in the bifactor models with ordered categorical data. Results support…

Within the frequentist structural equation modeling (SEM) framework, adjudicating model quality through measures of fit has been an active area of methodological research. Complicating this conversation is research revealing that a higher quality measurement portion of a SEM can result in poorer estimates of overall model fit than lower quality…

Dynamic structural equation models (DSEM) are designed for time series analysis of latent structures. Inherent to the application of DSEM is model parameter estimation, which has to be addressed in many applications by a single time series. In this context, however, the methods currently available either lack estimation quality or are…

Objective: Psychologists have a responsibility to conduct standardised assessment according to instructions in test manuals and guidelines in assessment texts. In practice, circumstances arise that are not addressed in manuals and texts. The aim of this study was to explore the ways in which experienced psychologists manage some of these issues.…

In this study, I explore my lived experience to evaluate an established team-teaching artefact. I achieve this by implementing an adapted meta-synthesis of retrospective, published individualised and co-authored autoethnography (MICA) methodology. The MICA framework was first penned by Hughes and Pennington (2021), which I adapt to determine the…

Hindu sacred scriptures are a rich interweave of cosmological revelation that is embedded in melopoeia (melodic poetry) and sung in designated meters during rituals, liturgical services, festivals, and personal prayers. Revelation is conveyed through enigmatic dialogues, debates, parables, anecdotes, legends, and narratives. These occur between…

This study examined the early implementation stages of the Modeling Method of Instruction (MMI) in the science classroom to find the most valuable strategies for effective implementation. In this qualitative study, eleven teachers were interviewed to uncover effective implementation strategies. Interview data were analyzed using the constant…

The purpose of this study was to explore the information, activities, and methods teachers take and apply to their classrooms and teaching after participating in a two year long professional learning (PL) cohort entitled "Equity and Inclusion in the Classroom." The PL was based on Hammond's (2015) "Ready for Rigor" framework…

This research investigates how three students' learning attributes--attitudes, behavior, and English proficiency background contribute to the students' writing performance. Statistical methods explored three primary areas: (1) the influence of students' attitudes towards the students' choice of teaching methods and learning behavior, (2) the…

As the 21st century progresses, we are increasingly reminded of the importance of and need for green chemistry, which also leads to the corresponding need for green chemistry education. The UC Berkeley Department of Chemistry developed a green chemistry laboratory curriculum-the "General Chemistry Green Curriculum" ("GC[superscript…

As teachers face barriers to communicating climate science, new ways of communicating and teaching are needed. This study explored new ways to educate about climate change while addressing the literature gap for how sound can communicate information about climate change and be used to increase learning and engagement. The purpose was to learn to…

Dissertation objectives included investigating how environment and plant life history influence aspects of leaf vascular infrastructure that supports photosynthesis, as well as photoprotection of the photosynthetic process. Additionally, I aimed to engage students in science and plant biology through innovative teaching methods. In summer annual…

This design case details a seven-year iterative design process to create an app for use in online physical education classes. Each iteration addresses the shortcomings of the previous version. The most recent iteration of the app allows students to use Fitbit™ devices to record heart rate data, which each student sees as progress toward course…

Music composition, particularly within the Chinese Yan Huang style, holds significance for its artistic merit and potential to enhance literacy development and foster cultural appreciation. This study delves into the literacy composition techniques employed by composer Bao Yuankai within the Chinese Yan Huang style, focusing on the piece…

Cirques are often the most representative and numerous landforms in alpine glaciated watersheds. The readily mappable and measurable nature of cirques (especially aspects and floor elevations) may yield information about the climatic, geologic, and topographic conditions that created them. These ubiquitous landforms are the foci of an alpine…
