As part of a longitudinal study, infant/toddler pretend play development and maternal play modelling were investigated in dyadic context. A total of 21 children were videotaped in monthly play sessions with their mothers, from age 8 to 17 months. Child and mother pretend play frequencies and levels were measured using Brown's Pretend Play…

Drawing on longitudinal data, this study explores the dynamic relationship between the development of conceptual knowledge of language and the emergence of sociostylistic variation in second language (L2) speech. Participants include eight intermediate-level US university learners of French who participated in a concept-based pedagogical…

Increasingly, children spend much of their day in the care of adults other than their parents, such as child care providers. Consequently, it is important to analyze nonparental adults' use of strategies suggested to foster language development, such as contingent responsiveness, during interactions with young children. This study examined…

An extensive research literature in education and psychology demonstrates positive effects of perspective-taking on various forms of learning. Until recently, perspective-taking has been limited to the mental simulation of how someone with different beliefs, knowledge, physical location, etc., perceives an object or event. Over the last decade…

The use of a video camera may markedly improve demonstrations of optical spectra. First, the output electrical signal from the camera, which provides full information about a picture to be transmitted, can be used for observing the radiant power spectrum on the screen of a common oscilloscope. Second, increasing the magnification by the camera…

Given the rise in students identified as having autistic-like characteristics that are impeding their ability to receive educational benefit without support, evidenced based interventions are a vital part of educational services. Children presenting with social and communication deficits require appropriate interventions in order to make progress…

Although stress is frequently claimed to impede foreign language (FL) reading comprehension, it is usually not explained how. We investigated the effects of stress, working memory (WM) capacity, and inferential complexity on Spanish FL readers' inferential processing during comprehension. Inferences, although necessary for reading comprehension,…

We report a simple experiment that clearly demonstrates a common error in the explanation of the classic experiment where a small piece of paper is put over a book and the system is let fall. This classic demonstration is used in introductory physics courses to show that after eliminating the friction force with the air, the piece of paper falls…

This study investigates designing and implementing a speaking course in which face-to-face instruction informed by the principles of Task-Based Learning is blended with the use of technology, the video, for the first-year student teachers of English in Turkish higher education. The study consisted of three hours of task-based classroom…

Picture the scene--a child in a class has brought in a fabulous example of a snake skin, a snail, a seed, a fossil or rock and the whole class wants to see it. How does a teacher allow them all to observe it without destroying it or jostling each other? One way to get around this issue is to use a visualiser. A visualiser is essentially a small…

Evaluators use their eyes to see what is there, whether it is intended or not. But they use their test instruments to measure what is intended, whether it is there or not. Evaluators have been broadening their repertoire of instruments for years: curriculum-embedded tests, observer checklists, audiotape recorders, videotape recorders, unobtrusive…

The major goals of the present study were to (a) examine age differences in susceptibility to age stereotypes and (b) test a self-awareness manipulation in counteracting age stereotypes. Young and older adults read two sets of descriptors that only differed in the to-be-ignored age-related information. In the high self-awareness condition,…

This article narrates how the use of video camera has transformed the life of Jack Williams, a 10-year-old boy from Colorado Springs, Colorado, who has autism. The way autism affected Jack was unique. For the first nine years of his life, Jack remained in his world, alone. Functionally non-verbal and with motor skill problems that affected his…

This investigation examined the effects of Classwide Peer Tutoring (CWPT), a variation of peer tutoring on the volleyball skills of four 6th grade middle school students purposefully selected from an intact class of 21 students. Participants were average to low skilled males and females. A single subject A-B-A-B withdrawal design was used to…

Classroom video excerpts are often used to help preservice and practicing teachers explore students' mathematical ideas. This article describes several types of video clips that the authors have found to be particularly productive for this purpose. The authors also discuss three dimensions that can be used to characterize the student thinking…
