Research purposes and design: This study aimed to compare the effects of different explicit approaches used in modeling-based instruction on students' understanding of scientific models and modeling (USMM). In Study 1, a self-study approach was compared to a preliminary explicit approach. In Study 2, preliminary explicit approach and embedded…

In this article, I provide the first publication thoroughly detailing how the theoretical foundation for the self-regulated strategy development (SRSD) instructional model was developed. I explain the development of the theoretical base for the SRSD model of instruction and the initial focus on writing instruction. I detail the reasoning and…

Students often learn about measurement uncertainty as an isolated topic, with a focus on generalizable strategies to manage uncertainty in scientific investigation. In this study, we report and analyze a case of emergent learning about measurement and uncertainty, in which students in a Chinese elementary school science class explored and…

The term social participation is widely used and has various meanings in different contexts. This article aims to enhance the understanding of social participation in science museums. The research was conducted using a cultural-historical perspective in six steps: (1) survey to identify the meanings attributed to the term social participation and…

This study examines the effects of universal public pre-kindergarten for 3-year-olds (Pre-K3) on later public education outcomes, including enrollment, school mobility, special education status, and in-grade retention from kindergarten through second grade. While universal pre-kindergarten programs typically target 4-year-olds, interest in…

The early care and education (ECE) sector in New Hampshire (NH) is a complex ecosystem that must account for families' needs and resources, the capacity and availability of the workforce, and the costs of providing services. This ecosystem is also bolstered (and constrained) by local, state, and federal policy. This series of primers, titled the…

The purpose of this article is to describe an emergent model that conceptualizes common experiences for nonbinary people as they explore and navigate their identities by synthesizing existing nonbinary identity development literature. We ground our manuscript epistemologically in queer theory, queer of color critique, and intersectionality theory.…

The study aimed to (1) investigate the components and indicators of active learning instruction competency among elementary school teachers, (2) examine the current state, desired state, and necessary requirements of active learning instruction competency among elementary school teachers, and (3) develop an educational supervision model based on…

When planning a cluster randomized trial, evaluators often have access to an enumerated cohort representing the target population of clusters. Practicalities of conducting the trial, such as the need to oversample clusters with certain characteristics in order to improve trial economy or support inferences about subgroups of clusters, may preclude…

In real-world situations, multidimensional data may appear on large-scale tests or psychological surveys. The purpose of this study was to investigate the effects of the quantity and magnitude of cross-loadings and model specification on item parameter recovery in multidimensional Item Response Theory (MIRT) models, especially when the model was…

Purpose: The purpose of this study is to determine the competency characteristics required for the employment of master's degree students in educational technology. Design/methodology/approach: A combined qualitative and quantitative method was used to consult multiple experts through a modified Delphi method. Competency characteristics were…

Social justice mathematical modeling is powerful in helping teachers build awareness of social issues, critique existing systems, and engage in rich mathematical reasoning. In this article, we document a task in which 28 preservice teachers (PSTs) explored if teacher pay is fair and how to define "fair" mathematically. Through…

School improvement planning can serve as a mechanism for school leaders to identify and address inequities. Yet, despite longstanding mandates, the empirical evidence base on school improvement plans (SIPs) is surprisingly limited, and even less literature focuses on the intersection of equity and school improvement planning. Using a conventional…

Mediation analysis is widely applied in various fields of science, such as psychology, epidemiology, and sociology. In practice, many psychological and behavioral phenomena are dynamic, and the corresponding mediation effects are expected to change over time. However, most existing mediation methods assume a static mediation effect over time,…

The article presents the application of 3D technologies in STEAM education through a conducted scientific research, highlighting the role of 3D modeling and 3D printing as an innovative approach in achieving an interdisciplinary learning model. The research included the following stages: preparation for designing a detailed 3D steam locomotive…
