Teachers can play critical roles in challenging or reinscribing dominant narratives about what counts as STEM, who is seen within STEM disciplines, and how these disciplines should be taught. However, teachers have often experienced STEM in limited ways in their own education and are thereby provided with few resources for re-imagining these…

We describe research results and lessons learned from a laboratory/classroom collaboration with a school system offering both traditional English-only education and a dual-language track (Spanish/English). Through this collaboration, we addressed basic research questions informing malleable factors that impact cognitive development. In a…

The development of math reasoning and 3-d mental rotation skills are intertwined. However, it is currently not understood how these cognitive processes develop and interact longitudinally at the within-person level -- either within or across genders. In this study, 553 students (52% girls) were assessed from fifth to seventh grades on 3-d mental…

Deictic linking gestures, hand and arm motions that physically embody links being communicated between two or more objects in the shared communicative environment, are explored in a cross-cultural sample of mathematics instruction. Linking gestures are specifically examined here when they occur in the context of communicative analogies designed to…

This volume provides a comprehensive and contemporary depiction of the swift evolution of learning technologies and the innovations that derive from their deployment in school education. It comprises cases studies, research focused on emergent technologies and experiments with existing tools in a wide range of scenarios. The studies included in…

There is increasing evidence of a relationship between orthographic processing skill, or the ability to form, store and access word representations, and reading ability. Empirical research to date has not, however, clarified the direction of this relationship. We examined this question in a three-year longitudinal study of children from Grades 1…

Two experiments examining the subsyllabic division behaviors of Chinese-speaking children learning English as a foreign language (EFL) are reported. In Experiment 1, target phonemes of monosyllabic English nonwords were varied in phonotactic context (e.g., (C)VC vs. (C)CVC), marginality (e.g., (C)CVC vs. C(C)VC), and/or position (e.g., (C)VC vs.…

Previous studies provided evidence of a relationship between mental rotation (MR) and motor processes in children and adults. However, there is no direct evidence that MR ability is a reliable predictor of success for motor performance. After completion of a MR test, the motor performance of 7- to 8-year-old and 11- to 12-year-old children was…

Previous research into face processing in autism spectrum disorder (ASD) has revealed atypical biases toward particular facial information during identity recognition. Specifically, a focus on features (or high spatial frequencies [HSFs]) has been reported for both face and nonface processing in ASD. The current study investigated the development…

French children program the words they write syllable by syllable. We examined whether the syllable the children use to segment words is determined phonologically (i.e., is derived from speech production processes) or orthographically. Third, 4th and 5th graders wrote on a digitiser words that were mono-syllables phonologically (e.g.…

To conceive the infinity of integers, one has to realize: (a) the unending possibility of increasing/decreasing numbers (potential infinity), (b) that the cardinality of the set of numbers is greater than that of any finite set (actual infinity), and (c) that the leap from a finite to an infinite set is itself infinite (immeasurable gap). Three…

Personal narratives are integral to autobiographical memory and to identity, with coherent personal narratives being linked to positive developmental outcomes across the lifespan. In this article, we review the theoretical and empirical literature that sets the stage for a new lifespan model of personal narrative coherence. This new model…

The apparent optionality in the use of null and overt pronominal subjects and the apparently free word order or distribution of preverbal and postverbal subjects in Spanish obey a number of discourse-pragmatic constraints which play an important role in Spanish L2 subject development. Although research on subject properties at the syntax-discourse…
