This study explored whether a daytime nap aids children's acquisition of letter-sound knowledge, which is a fundamental component for learning to read. Thirty-two preschool children in Sydney, Australia (M[subscript age] = 4 years;3 months) were taught letter-sound mappings in two sessions: one followed by a nap and the other by a wakeful period.…

Research has found mixed evidence for the production effect in childhood. Some studies have found a positive effect of production on word recognition and recall, while others have found the reverse. This paper takes a developmental approach to investigate the production effect. Children aged 2-6 years (n = 150) from a predominantly white…

Measurement is a critical component of mathematics education, but research on the learning and teaching of measurement is limited. We previously introduced, refined, and validated a developmental progression -- the cognitive core of a learning trajectory -- for length measurement in the early years. A complete learning trajectory includes…

Children's Approaches to Learning (AtL) represents how children seek learning opportunities in their classrooms. It can include children's persistence, attention, and initiative. It has often been studied using a composite of a teacher-rated scale. However, person-centered approaches may account for heterogeneity in children's learning approaches,…

Prior work showed that infants look longer at impossible figures than possible ones, although it is unclear whether they or older children understand "impossibility." We employed a series of matching and sorting tasks with pictures and objects to evaluate children's knowledge of this dimension. In Experiment 1, nearly all children…

Executive Functions (EFs) are crucial top-down processes characterized by cool and hot aspects, required for goal-directed behaviour. Only a few studies evaluated and trained concurrently cool and hot EFs. Therefore, we promote a training aiming to enhance both EFs components. A total of 91 children attending the second year of kindergarten were…

Wayfinding is one of the most important skills that children have to learn in order to safely move in the environment. One problem that 5-year-old children encounter with wayfinding is changing their point of view to that of another person in different position in the same environment, such as that of a person opposite them whose perspective is…

The competence in identifying and comprehending the meaning of idiomatic expressions developed at an early age. However, second language learners reach the comprehension skill differently within the age and at pace. There are many unresolved questions regarding the age which children start to comprehend L2 idioms. The objective of this study was…

This research investigates the effect of production on 4.5- to 6-year-old children's recognition of newly learned words. In Experiment 1, children were taught four novel words in a produced or heard training condition during a brief training phase. In Experiment 2, children were taught eight novel words, and this time training condition was in a…

This study explored the development of theory of mind (ToM) in 80 Swedish-speaking 3- to 5-year-olds, a previously unstudied language and culture. The ToM scale was translated and tested in a Swedish context. The results show that the ToM abilities improve significantly with age. In addition, a gender difference was observed for the whole sample,…

This study investigated transfer effects of gaze-interactive attention training to more complex social and cognitive skills in infancy. Seventy 9-month-olds were assigned to a training group (n = 35) or an active control group (n = 35). Before, after, and at 6-week follow-up both groups completed an assessment battery assessing transfer to…

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…

Within teacher education, there is ongoing debate about the nature and extent of the propositional and conceptual knowledge that teachers need. In this paper we interrogate the learning tasks detailed in six learning modules offered in a formal qualification for South African Foundation Phase (grade R-3) teachers. Our purpose is to analyse to what…

This study investigated the relation between theory of mind (ToM) and metamemory knowledge using a training methodology. Sixty-two 4- to 5-year-old children were recruited and randomly assigned to one of two training conditions: A first-order false belief (ToM) and a control condition. Intervention and control groups were equivalent at pretest for…

We present a synthesis of findings from constructivist teaching experiments regarding six schemes children construct for reasoning multiplicatively and tasks to promote them. We provide a task-generating platform game, depictions of each scheme, and supporting tasks. Tasks must be distinguished from children's thinking, and learning situations…
