Why is instructional gesture ineffective in some contexts? And what is it about learners that predicts whether they will learn from gestures? This between-subjects linear measurement training study compares gesture instruction to two controls--operant action and transient action--in a diverse sample of first-grade students (N = 174, M[subscript…

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…

One of the core functions of explanation is to support prediction and generalization. However, some explanations license a broader range of predictions than others. For instance, an explanation about biology could be presented as applying to a specific case (e.g., "this bear") or more generally across "all animals." The current…

Questioning is a core component of formal pedagogy. Parents commonly question children, but do they use questions to teach? This article defines "pedagogical questions" as questions for which the questioner already knows the answer and intended to help the questionee learn. Transcripts of parent-child conversations were collected from…

Two studies examined the role of intention in preschoolers' understanding of teaching. Three- to 5-year-olds judged stories in which there was an intention to teach or not (teaching vs. imitation) for 4 different learning outcomes (successful, partial, failed, and unknown). They also judged 2 stories with embedded instructional intent (e.g.,…

Imitation, vocabulary, pretend play, and socially insightful behavior were investigated in 5,206 same- and opposite-sex 2-year-old twin pairs in the United Kingdom. Individual differences in imitative ability were due to modest heritability (30%), while environmental factors shared between twins (42%) and unique to each twin (28%) also made…

In order to examine the effects of interrogative strategies in promoting children's associative learning, children five and six years of age, as well as sixth-grade children, were first presented with a variety of picture-paired associates and then tested for the ability to memorize them. (MP)

Purpose of the study was to evaluate the effectiveness of a hierarchically arranged instructional program in multiple classification, which refers to the ability to define a class by two or more attributes simultaneously. (Authors/MB)

Studies were conducted in Chinese, Japanese, and American classrooms during mathematics classes. Large cross-cultural differences were found in variables related to classroom structure and management. These paralleled differences in mathematics achievement among China, Japan, and the United States. (PCB)
