Foundations of statistics research aims to establish fundamental principles guiding inference about populations under uncertainty. It is concerned with the process of learning from observations, notions of uncertainty and induction, and satisfying inferential objectives. The growing interest in predictive methods in high-stakes fields like…

Noticing is an essential skill for all teachers of mathematics. Mathematics teacher educators have utilized a variety of tools to practice and develop preservice teachers' (PSTs') ability to notice, which we extend to include photographs and learning trajectories. This article explores PSTs' noticing skills by analyzing work samples from a methods…

Given the inclusion of sensory reactivity as a diagnostic criterion for autism spectrum disorder (ASD) and the theorized etiological role of sensory reactivity in the development of autism, adequate sensory measures of sensory reactivity in autism, including measures extending to use in infancy, are needed. Adequate sensory measurement relies on…

In the United States, educators are tasked with responding to the increased needs of diverse K-12 students in mainstream classrooms through co-teaching roles that require collaborative partnerships. The purpose of this qualitative descriptive study was to understand how students in teacher preparation programs within the United States describe the…

Research into student affect detection has historically relied on ground truth measures of emotion that utilize one of three sources of data: (1) self-report data, (2) classroom observations, or (3) sensor data that is retrospectively labeled. Although a few studies have compared sensor- and observation-based approaches to student affective…

In this study, we investigated how early childhood teachers' perspectives on their enacted literacy instruction aligned with the perspectives of observers of that same instruction. Two master teachers and two researchers, all with early childhood expertise, observed and reported their perspectives of 45 instances of literacy instruction. These…

To achieve the goal of cultivating students' scientific modeling competence, it is crucial to improve teachers' epistemic knowledge and skills with respect to modeling-based teaching. Taking into consideration existing studies on enhancing teaching competence and teachers' professional development on modeling, and the importance of classroom…

Compulsory schemes that extend peer review beyond classroom observation are rare. The institution within which this study sits implements one such example named peer support. By drawing upon data from one faculty, the peer support scheme, which has been in operation since 2009 is placed under a research-led critical review. Whilst the scheme is…

Montessori was very specific about the value of observation. Observation may feel like a never-ending chore--a routine that is difficult to fit into the day that results in data that is difficult to use once collected. No matter the reason, observation can inspire feelings of discomfort, inadequacy, and confusion. Viewed from this perspective,…

The Optimizing Learning Opportunities for Students (OLOS) Observation System was developed by the Early Learning Network's assessment team at the University of California, Irvine. OLOS is a user-friendly, web-based tool designed to help teachers understand what is happening in their classrooms and uncover ways to meet the unique learning needs of…

Infants who receive better counting input at home tend to become toddlers with better number knowledge in preschool. However, for many children, in-person counting experience is not always available, despite educational media becoming increasingly prevalent. Might virtual counting experience benefit the young mind? Using a novel online looking…

There is a critical need for high-quality clinical outcome assessments to capture the important aspects of communication ability of individuals with Angelman syndrome (AS). To center the perspective of caregivers, our team developed the novel Observer-Reported Communication Ability (ORCA) measure using best practice guidelines, with the goal of…

The family resemblance approach to nature of science is receiving increasing attention by science educators since its inception about a decade ago. Many scholars of science education have contributed and continue to contribute to it not only theoretically but also by applying it empirically to a wide range of areas such as curriculum and textbook…

In this study, we examine "what went wrong" in our professional development program for encouraging cognitively demanding instruction, focusing on the difficulties we encountered in using an observational tool for evaluating this type of instruction and reaching inter-rater reliability. We do so through the lens of a discursive theory of…

Objective: The precise measurement of treatment fidelity (quantity and quality in the delivery of treatment strategies in an intervention) is essential for intervention development, evaluation, and implementation. Various informants are used in fidelity assessment (e.g., observers, practitioners [clinicians, teachers], clients), but these…
