Working memory (WM) is a critical cognitive system that supports processing a variety of information. Remembering different types of objects may impose different levels of cognitive demands on WM performance. In the present study, we examined 205 children's WM in representing different types of content and its developmental trajectories in early…

We propose a simple computational model that describes potential mechanisms underlying the organization and development of the lexical-semantic system in 18-month-old infants. We focus on two independent aspects: (i) on potential mechanisms underlying the development of taxonomic and associative priming, and (ii) on potential mechanisms underlying…

Evaluating evidence and restructuring beliefs based on anomalous evidence are fundamental aspects of scientific reasoning. These skills can be challenging for both children and adults, especially in domains where they possess inaccurate prior beliefs that can interfere with the acquisition of correct scientific information (e.g., heavier objects…

In many cultural contexts, judging another as conscious or not has profound practical, legal, and philosophical consequences. However, little research focuses on how our ability to make such judgements arises. Thirty years ago a classic set of studies by Flavell et al. demonstrated that children do not develop a complex understanding of conscious…

The notion of children's working theories is an overarching outcome of Aotearoa New Zealand's early childhood curriculum document "Te Whariki." An ever-growing base of research and literature is available about the working theories children hold and ways that teachers might support working theory development. In this article, I draw on…

This paper attempts to address challenges identified by Michael Young and those arising from his writings on 'powerful knowledge' to gain a deeper insight into the relationship between everyday horizontal knowledge and disciplinary vertical knowledge as well as how we can approach it in a way that benefits pedagogy. The attempt includes the move…

Pretend play is often hypothesized in a global sense to be an effective context for young children's learning, but there is much still to learn about whether all types of information can be learned equally and whether all types of pretend play are equally beneficial. The present study tests whether preschoolers can learn a simple, novel causal…

The standard view on Theory of Mind (ToM) is that the mastery of the false belief (FB) task around age 4 marks the ontogenetic emergence of full-fledged meta-representational ToM. Recently, a puzzling finding has emerged: Once children master the FB task, they begin to fail true belief (TB) control tasks. This finding threatens the validity of FB…

Generating own examples for previously encountered new concepts is a common and highly effective learning activity, at least when the examples are of high quality. Unfortunately, however, students are not able to accurately evaluate the quality of their own examples and instructional support measures such as idea unit standards that have been…

Enhancing students' conceptual understanding is one of the primary goals of science education. Existing literature suggests that the degree of knowledge integration among students can reflect their level of conceptual understanding. This study focuses on the concept of friction force, constructing a cognitive structure model of friction force to…

Algebra is critical in shaping future mathematics success and is integral to the K-12 curriculum. Despite its inclusion, a common challenge arises as students' progress to higher grades without a solid foundation, resulting in challenging learning experiences. This action research study focuses on the algebraic learning experience of a Grade 7…

Cognitive development of eighth-grade students, as identified by Jean Piaget, occurs during a time when many of them are transitioning between concrete operations and formal operations where the ability to think in abstract concepts becomes possible. Because of this period of transition, many eighth-grade students find difficulty in demonstrating…

A case study of calculus instructional material (comprising of lecture notes and tutorial practice worksheets) designed by teachers from a Singapore pre-university is presented in this paper. As textbooks have not been available for mathematics at the pre-university levels, the instructional material was a product of the teachers' collaborative…

This study examined the effect of gamification on visual programming and computational thinking skills among primary school students, aiming to investigate how gamified learning environments enhance cognitive skill development and conceptual integration compared to traditional teaching methods. A quasi-experimental design was employed, involving…

Multilingual college students often struggle with writing and revising for academic purposes. This dissertation explored the effectiveness of a Concept-Based Language Instruction (C-BLI) approach to teaching revision processes to college-level multilingual writers. Although a significant body of research exists on effective feedback on…
