Most American classrooms employ a teacher-text-centered model of instruction that is misaligned with the developmental science of how children naturally learn. This article reviews that science and the origins of the common instructional model, including three modifications intended to make it work better (grades, age-graded classrooms, and…

Although there is a rich literature on children's strategies for remembering, little attention has been paid to characterizing developmental change within individual children and to examining mediators that may bring about such change. To address these issues, we assess children's memory skills over time while simultaneously examining…

Purpose: To evaluate the validity, reliability, and sensitivity of the novel Means-End Problem-Solving Assessment Tool (MEPSAT). Methods: Children with typical development and those with motor delay were assessed throughout the first 2 years of life using the MEPSAT. MEPSAT scores were validated against the cognitive and motor subscales of the…

The current paper investigates the structural validity of the Children's Concentration and Empathy Scale (CCES), which was designed based on Montessori's developmental theory to assess, using teacher ratings, the coherence of attention-related characteristics (concentration, empathy, and normalization) in children from 1.5 to 12 years old. The…

Universal screening and progress monitoring are evidence-based practices in early intervention/ early childhood special education (EI/ECSE). Individual Growth and Development Indicators (IGDIs) for infants/toddlers are measures that programs can use for universal screening, progress monitoring, intervention decision-making, and accountability.…

Engaging, focusing, and persisting in the completion of tasks are among the skills needed for school success. Tracking whether a child is learning cognitive problem-solving skills is essential in knowing if they are acquiring skills important for development and school readiness; and if not, how they are responding to early intervention. Use of…

Developmental science demonstrates that younger children (ages 4 to 8) are capable of making meaning of their contexts and the self. Yet, younger children's meaning making is largely absent from intervention and implementation research on early childhood policies. This absence is notable given the rise in investment in early childhood policies and…

The emphasis on social-emotional competence and its importance to positive academic and nonacademic outcomes has led to a focus on identifying and implementing effective practices for supporting young children's social-emotional competence. Our work to identify, validate, and support the fidelity of implementation of evidence-based practices to…

This paper presents evidence of the score reliability, factor structure, criterion-related validity, and measurement equivalence of a web-based assessment of several important social and emotional competencies for children in fourth through sixth grades. The assessment, SELweb LE (Late Elementary), is designed to measure children's understanding…

The assessment of psychosocial strengths in children and adolescents has predominately focused on the measurement of single traits and constructs, such as grit (Christopoulou, Lakioti, Pezirkianidis, Karakasidou, & Stalikas, 2018), optimism (Oberle, Guhn, Gadermann, Thomson, & Schonert-Reichl, 2018), hope (Pedrotti, 2018), and gratitude…

Although high-quality early care and education (ECE) is widely accepted as one of the most effective means for promoting early learning and development, many ECE programs have limited impact perhaps because of issues with how ECE quality is defined and measured. This study seeks to expand definitions of ECE quality by asking which preschool ECE…

Mathematical discussions in which students compare alternative solutions to a problem can be powerful modes for students to engage and refine their misconceptions into conceptual understanding, as well as to develop understanding of the mathematics underlying common algorithms. At the same time, these discussions are challenging to lead…

School reform is an important national and international concern. The Montessori alternative school system is unique in that it is well-aligned with the science of healthy development and learning, has strong social-emotional "and" academic outcomes, is virtually unchanged in over a century, can be applied across all the school years,…

Research Findings: The Early Childhood Environment Rating Scale, Revised (ECERS-R) is widely used, often to evaluate whether preschool programs are of sufficient quality to improve children's school readiness. We examined the validity of the measure for this purpose. Item response theory (IRT) analyses revealed that many items did not fit together…

There are many continuous quantitative dimensions in the physical world. Philosophical, psychological and neural work has focused mostly on space and number. However, there are other important continuous dimensions (e.g., time, mass). Moreover, space can be broken down into more specific dimensions (e.g., length, area, density) and number can be…
