An Equity-Based And Culturally Responsive Bill Of Rights For Early Childhood Students Of Color With Exceptionalities, Evette Simmons-Reed, Michelle Frazier Trotman Scott, Gloria Tardash, Mildred Boveda, Donna Y. Ford May 2026

An Equity-Based And Culturally Responsive Bill Of Rights For Early Childhood Students Of Color With Exceptionalities, Evette Simmons-Reed, Michelle Frazier Trotman Scott, Gloria Tardash, Mildred Boveda, Donna Y. Ford

Perspectives on Early Childhood Psychology and Education

The COVID-19 pandemic exacerbated existing disparities in early intervention (EI) and early childhood special education (ECSE) services for culturally and linguistically diverse (CLD) disabled children, exposing critical gaps in access, services and support. systemic inconsistencies in implementation, training, and funding, remain barriers limit opportunities for CLD students to benefit, despite the aims of the Individuals with Disabilities Improvement Act (IDEA). To address these inequities, this manuscript proposes an expanded and updated Culturally Responsive Equity-Based Bill of Rights for EI and ECSE. Building upon Ford and colleagues' (2018) work, this revised document extends protections to children aged zero to five, emphasizing …


Latent Transition Analysis: A Statistical Method For Identifying Underlying Subgroups Over Time, Holmes Finch May 2026

Latent Transition Analysis: A Statistical Method For Identifying Underlying Subgroups Over Time, Holmes Finch

Perspectives on Early Childhood Psychology and Education

Researchers working in early childhood research are often interested in assessing change over time in multiple variables. In addition, they may wish to ascertain whether there exist subgroups in the data with respect to these variables, and whether/how membership in these groups is related. Latent transition analysis (LTA) provides such researchers with a useful tool for investigating questions around such groups, including their composition, frequency, and the likelihood of moving from one to another at different points in time. The purpose of this manuscript is to provide a full demonstrate of LTA and show how it can be used to …


Comparison Of Multidimensional Models For Extreme Response Styles, Holmes Finch, Brian French May 2026

Comparison Of Multidimensional Models For Extreme Response Styles, Holmes Finch, Brian French

Perspectives on Early Childhood Psychology and Education

Self-administered scales are ubiquitous throughout the social sciences. Therefore, it is crucial that they properly reflect the measured latent trait(s), and are not influenced by other factors. One potential threat to validity is the response style favored by an individual completing the items. In particular, a tendency to engage in extreme responding (ERS) can result in a tendency to provide responses in the outer range of the response scale, independent of the actual level of the response to the item. The purposes of this study was to demonstrate how these models can be used to account for ERS in practice, …


A Tutorial For Identifying And Comparing Change Points In Developmental Trajectories, Holmes Finch May 2026

A Tutorial For Identifying And Comparing Change Points In Developmental Trajectories, Holmes Finch

Perspectives on Early Childhood Psychology and Education

Researchers in a variety of social science fields work with sequential data, such as measurements made over time. In some instances, one or more of the moments (e.g., mean, variance) of the series may change abruptly at some point in the sequence, yielding what is known as a change point. There is a broad literature describing methods for changepoint detection. Researchers working with multiple sequential series containing change points may be interested in comparing the locations of these changes. The purpose of this manuscript is to demonstrate how a researcher can detect changepoints and compare changepoints between two or more …


Using Multilevel Modeling To Understand Nested Data, Holmes Finch May 2026

Using Multilevel Modeling To Understand Nested Data, Holmes Finch

Perspectives on Early Childhood Psychology and Education

Researchers in the social sciences often work with nested data, in which individuals are collected in higher level clusters. For example, educational research often involves working with samples in which students are nested within schools. Standard data analyses, such as regression and analysis of variance (ANOVA), yield statistically biased results when this nested structure is ignored. One widely used and effective approach for handling such nested data is multilevel modeling. The purpose of this manuscript is to review the basics of multilevel modeling and to provide the reader with a fully worked example in which the analytic approach and results …


Using Effect Sizes, Confidence Intervals, And The Bayes Factor To Better Understand The T-Test, Analysis Of Variance, And Regression Results, Holmes Finch May 2026

Using Effect Sizes, Confidence Intervals, And The Bayes Factor To Better Understand The T-Test, Analysis Of Variance, And Regression Results, Holmes Finch

Perspectives on Early Childhood Psychology and Education

Null hypothesis testing is a widely used paradigm for assessing research hypotheses across the social sciences. Despite their ubiquity, researchers have discussed a number of problems and limitations to hypothesis testing and have suggested alternatives that might provide greater depth and explanation of research results. The purpose of this paper is to describe the use of several such alternatives and to show how they can be integrated with one another and with null hypothesis testing in order to provide a more holistic view of research hypotheses.
