Responsive teaching is an effective teaching approach in which teachers engage and respond to students' mathematical ideas to support their mathematics learning. In this study, the relationship between preservice teachers' (PSTs) noticing expertise and their teaching moves was investigated in a simulated AI chatbot environment. The AI chatbot…

Autism spectrum disorder presents as a multifaceted condition characterized by pronounced impairments in social communication and behavioral patterns. Diagnosis hinges upon the expertise of clinicians, comprehensive developmental history, and observation of specific behavioral markers. However, in low-income countries, access to screening tools…

The National Institute of Mental Health created the National Database for Autism Research (NDAR) to accelerate autism knowledge through data sharing and collaboration. However, our experience using NDAR reveals systematic challenges across several aspects of data submission, selection, management, and analysis that limit utility of this resource.…

Online ethnography is a research approach that adapts traditional ethnographic methods for studying communities that exist online. This case study reports on an online ethnography of Webheads in Action (WiA), an online community of English language teachers, founded in 2002. In this online ethnographic research, I examined how the Webheads…

Telecollaboration in pre-service teacher education promotes intercultural communicative competence and bridges knowledge and practice. Although a growing body of studies has addressed the affordances of telecollaboration for developing student-teachers' (STs') competencies, research focusing on their knowledge of classroom interaction--and on…

Pearson's product-moment correlation can be explained by means of the probability of concordant pairs of observations on two continuous variables (ie, the order of the observations from two randomly selected individuals is the same between the two variables). The probability of concordant pairs features relatively easy computation and offers an…

There is nothing new about teacher educators collaborating across Europe, but when the surging pandemic required extraordinary creativity in the spring of 2020, two art teachers in early childhood education (ECE) in Serbia and Norway--improvised by teaching with what they had on hand: short videos of the first author's son that simulated what…

Patricia Carini valued children's own play and work--writing, drawing, sculpting, building--as a critical mode of meaning-making and learning. Modern education often places little emphasis on such play and work: standards-based programs and projects absorb every moment of the school day, often requiring even more time than is available. Yet…

Given the recent attention on early childhood mathematics education, it is important to understand how early childhood educators conceptualize the work of mathematics teaching and learning. This article describes a study of preschool educators' conceptions of mathematics teaching and learning in the context of a multi-year professional development…

Teacher noticing can be an important element in improving teaching and students' mathematical success. While the focus of the international project "Learning from Lessons" was on teacher learning, in this paper we report what mathematics teachers noticed and claimed to learn through the process of planning, teaching, and reflecting on…

Does the choice of observation instrument make a difference in the feedback and ratings that teachers receive? This study explores how lessons are rated differentially across various observation instruments. To investigate this question, ten randomly selected mathematics lessons were rated using six different observation instruments. Overall…

Electrochemistry is a branch of chemistry concerned with the interrelation of electrical and chemical effects, in which mathematical equations are employed to describe the fundamental principles of electrode processes and measurement methods. In this work, we present a graphical simulation that provides visual observations of dynamical behavior…

Instructional videos are widely used to study teachers' professional vision. A new technological development in video research is mobile eye-tracking (MET). It has the potential to provide fine-grained insights into teachers' professional vision in action, but has yet been scarcely employed. We addressed this research gap by using MET video…

Face-processing deficits, while not required for the diagnosis of autism spectrum disorder (ASD), have been associated with impaired social skills--a core feature of ASD; however, the strength and prevalence of this relationship remains unclear. Across 445 participants from the NIMH Data Archive, we examined the relationship between Benton Face…

This study is a qualitative investigation of caregiver-child interactions, involving 15 autistic children who are in the early stages of language learning. Data consisted of 15-min videos of free-play interactions recorded in a University clinic. We use conversation analysis to examine the sequence organization of proposal episodes, where the…
