From an early age, children apply the mutual exclusivity (ME) assumption, demonstrating preference for one-to-one mappings between words and their referents. However, for the acquisition of referentially overlapping terms, ME use must be suspended. We test whether contextual cues to intended meaning, in the form of presence of a speaker, may be…

Children are both shrewd about whom to copy--they selectively learn from certain adults--and overimitators--they copy adults' obviously superfluous actions. Is overimitation also selective? Does selectivity change with age? In two experiments, 161 two- to seven-year-old children saw videos of one adult receiving better payoffs or more bystander…

A classroom activity is presented, which can be used in teaching students statistics with an easily generated, large, real world data set. The activity consists of analyzing a video recording of an object. The colour data of the recorded object can then be used as a data set to explore variation in the data using graphs including histograms,…

The language of school is demanding; much of the content is decontextualized and abstract, and it concerns matters that are far removed from the daily life. Students are expected to learn about rain forests and prime numbers, literary motifs, and historical events that occurred centuries ago. Consider the additional cognitive demands confronting…

In many states, electric fences are used to prevent animals from leaving a designated area, for example for grazing. They are quite well known by most students and can therefore serve as daily-life examples of electric circuits. Besides helping to grasp the ideas of Kirchhoff's laws for voltages and currents in circuits according to loop and…

Basic understanding of nuclear science enhances our daily-life experience in many areas, such as the environment, medicine, electric power generation, and even politics. Yet typical school curricula do not provide for experiments that explore the topic. We present a means by which educators can use the ubiquitous webcam and inexpensive sources of…

Viewing of online videos and television segments has become a popular and efficient way for Extension audiences to acquire information. This article describes a unique approach to teaching on camera that may help Extension educators communicate their messages with comfort and personality.

Hand-raising is an extremely useful device for classroom self-selection. There are instances, however, where hand-raising is concurrently employed with the self-selector's onset of speaking, while teacher invitation or nomination is absent. Although it appears to be one way for would-be self-selectors to successfully seize the floor, the…

This single case design study examined the effects of video modeling (VM) using an augmented reality iPad application on improving phonics skills of first-grade students who struggle with reading. Results indicated that all students made significant growth in their phonics performance and maintained the intervention gains for 5 weeks following the…

Emphasis manipulation is a way to help learners by directing their attention to particular subcomponents of a learning task. This study investigated the effects of different approaches to emphasis manipulation on knowledge transfer and cognitive load. This was done by examining the impact of three task selection strategies: system-controlled,…

This study investigated science classroom discourse in terms of the types of teacher discursive moves (TDMs) and the relationships between the types of TDMs and student-led cognitive contributions in different science concepts by considering the classroom context. An experienced seventh-grade science teacher and her 19 students were engaged in…
