Problem-based learning (PBL) offers a powerful approach to engage students in meaningful learning experiences by connecting classroom content to real-world challenges. This Spotlight explores how PBL can be implemented across K-12 to foster critical thinking, collaboration, and problem-solving skills. From preparing students for the workforce…

In 2 experiments, I studied the effects of an Equivalence Based Instruction (EBI) math intervention on the emergence of untaught selection responses and abstraction to production responses. In Experiment I, using a multiple baseline design, I implemented the EBI intervention among a group of 17 first grade participants with varying levels of math…

This study used a person-centered approach to examine mother-daughter dyad behaviors when jointly solving addition problems during a card game. The goal was to identify maternal and child profile behaviors during the interaction as predictors of children's autonomous addition accuracy and strategy use at the end of first grade. Videotaped…

We investigated whether preschoolers' social-emotional competencies predict their peer relationships and academic achievements during grade one. Measures of cool and hot executive functions, theory of mind, social-problem-solving, and peer acceptance were administered to a sample of 48 preschoolers (M = 77.91 months). Academic achievement and peer…

The study aims at examining the effects of Engineering Design Process Based STEAM activities applied with tales on the creativity and problem-solving skills of 6-6.5 year-old students. The research was carried out with a pre-test, post-test, and quasi-experimental design with the control group. The research participants consisted of students…

STEM education in the early childhood grades is continuing to evolve. This study investigated the responses of children in first grade when they were engaged in STEM lessons throughout one school year. Qualitative data were collected from one classroom of eighteen children and one classroom teacher extracted from student and teacher artifacts,…

Question asking plays a fundamental role in learning, and the cognitive development literature contains many studies of specific types of question-asking skills. However, little is known about the developmental course across different aspects of question asking, of which we explore: (a) the ability to ask questions that enable children to solve a…

A theoretical framework grounded in constructionism and pragmatism theories supported research on learning by doing. This framework underpinned the purpose of this qualitative case study to explore how K-8 STEM teachers facilitated projects utilizing innovative technologies to solve community-based problems. The problem was a lack of connection…

This study explored the role of growth in the executive components of working memory (WM) on second language (L2) mathematical problem-solving in elementary school children who are emerging bilinguals whose first language (L1) is Spanish. To this end, children (N = 429) in Grades 1, 2, and 3 at Wave 1 were administered a battery of math, reading,…

Few Spanish language tools are available for assessing important social-emotional learning (SEL) skills. The present study presents evidence of the psychometric properties of a Spanish-language version of SELweb (SELweb-S), a web-based system for assessing children's ability to recognize others' emotions and perspectives, solve social problems,…

The authors detail word-learning strategies from a small-scale early reading intervention for first graders (N = 3) focused on Greek and Latin roots in science-based informational texts. Educators can provide explicit instruction to support student awareness of word structures in content-specific vocabulary, and this instruction can be adapted to…

Spatial abilities--required in both academic and everyday information processing--are recommended as an important target for explicit instruction in the K-12 curriculum. However, most school curricula do not address this spatial issue, probably because spatial ability is a general rather than domain-specific skill and also due to debate regarding…

Using a cluster-randomized controlled trial research design, this study investigates the effect of the first year of a three-year teacher professional development program on grades 1 and 2 student achievement in mathematics. Although the findings reported in the present report do not meet the standard cutoff for statistical significance (e.g., 95%…

This article presents results from two studies that included ethnically and socioeconomically diverse samples totaling 4,462 children in kindergarten through third grade. Each study examined the psychometric properties of a web-based, self-administered battery of assessments of social-emotional comprehension called "SELweb." Assessment…

This report describes efforts to measure teachers' knowledge of their own students' abilities in mathematics and offers preliminary findings. It provides a description of the sample, a description of the study design and its realization, and descriptive statistics for teacher judgment accuracy. The work described here was completed as part of a…
