The aim of this study was to examine the developmental trajectories of comprehension of relational concepts among 557 participants with intellectual disability (ID) of undifferentiated etiology (M age = 12.20 years, SD = 3.18) and 557 typically developing (TD) participants (M age = 4.57 years, SD = 0.80). Logistic regression analyses, with…

Infants and toddlers experience the world in interaction with others. Likewise, social interactions are important in learning about math--concepts of number ("one," "two," "three"), space ("on top," "upside-down," "round"), and magnitude ("more," "big,"…

There is growing interest in mathematics learning progressions in early childhood education. Counting is a skill usually developed early in life. The application of the counting principles in early childhood typically entails counting objects. This poses challenges for learning about zero. Indeed, the word "zero" is seldom used in the…

In order for children to understand and reason about the world in an adult-like fashion, they need to learn that conceptual categories are organized in a hierarchical fashion (e.g., a dog is also an animal). While children learn from their first-hand observation of the world, social knowledge transmission via language can also play an important…

Marsh et al.'s tests of appropriate spatial relationship concepts were administered to groups of college students to determine whether learning GIS enhances students' overall ability to generate and recognize fundamental spatial relationship concepts. 119 undergraduate students enrolled in various GIS courses and in non-GIS courses participated in…

Julia Kearney and Lori Bingham (pseudonyms), two middle school social studies teachers in a large urban school, have a problem. They want to have their students asking and exploring important questions about American history, and they want them to have the vocabulary knowledge needed to do so. While Julia and Lori recognize the rich linguistic…

The current quantitative study, a naturalistic field experiment, was conducted in a public primary school in Soweto, Johannesburg, with the objective to examine how children's achievement on four assessments at the beginning of Grade R, namely their numeracy, their mathematics-specific vocabulary, their executive functions, and their logical…

Empirical evidence is insufficient on the specific roles GIS learning plays in developing students' understanding various spatial concepts. The present study aims to draw attention to common struggles of learning some spatial concepts in geography and offer directions for future research on GIS learning and the development of student spatial…

Embodied models of language comprehension assume that words become associated with sensorimotor experiences during word learning. Novel word learning paradigms may provide insight into embodied effects, but studies in this domain have yet to account for how concepts and information known in first language (L1) might influence the sensorimotor…

While existing research into L2 classroom discourse has highlighted how knowledge and knowledge positions are negotiated, no attention seems to have been paid to what might be called "conceptual epistemic domains." Drawing on 22 hours of video-recorded data from Iranian EFL classrooms, our conversation analytic study illustrates how…

Our study examined the effects of culturally responsive literacy pedagogical approaches in the development of scientific vocabulary and conceptual knowledge among minoritized middle-grade students during a summer program. We describe the design and implementation of a literacy-enriched STEM instructional unit of study built upon the background…

This article is a qualitative study that explored bilingual/ESL science teachers' reflections about subject matter knowledge (SMK) and instructional practice in the elementary grades. Thirty-three teachers were part of a 5-year professional development program designed to enhance instructional quality and effectiveness to teach English learners.…

For food research, control, and production, valid and trustworthy analytical data are important. Our practical chemical food safety course for engineers therefore uses real-life studies for the ease of understanding the concept and the needed requirements for high analytical quality in relation to enabling correct evaluation of chemical food…

The assessment data in La Frontera School District suggests a need for improving instructional practices for middle school emergent bilingual migrant students' language and reading development. One possible solution to the language and literacy issues maybe introducing cognates. Cognates are words with identical or similar orthography and meaning…

Several studies have explored the use of iconic gestures to improve the learning of foreign vocabulary. In this quest, words for abstract concepts have been largely neglected, under the assumption that abstract concepts have poor or non-existent sensory-motor representations. Yet, the Conceptual Metaphor Theory suggests that they are grounded on…
