Although observation largely takes into account the needs and abilities of individuals with profound intellectual and multiple disabilities, several difficulties are related to this assessment method as well. Our aim in this study was to investigate what possibilities the use of physiological measurements make available to validate alertness…

We propose the use of Tracker, freeware for video analysis, to analyse the moment of inertia ("I") of a cylindrical plate. Three experiments are performed to validate the proposed method. The first experiment is dedicated to find the linear coefficient of rotational friction ("b") for our system. By omitting the effect of such friction, we derive…

This article discusses findings from a two-day teacher conference focusing on discursive authority and sociocultural positioning in mathematics classrooms. The conference was designed to study how research on classroom discourse could be transformed into effective professional development activities. We describe how the focus on discourse,…

This article aims to offer both a theoretical contribution and examples of practices of trust building in peace education; the article presents an empirical analysis of videotaped interactions in the context of peace education activities in international groups of adolescents. The analysis aims to understand if and in which ways peace education is…

This article examines a science teacher's use of and reflections on classroom talk in teaching a unit on genetics on a bilingual education programme. Constructivist, sociocultural and discursive psychological perspectives on conceptual change and classroom talk are reviewed. Data are drawn from three sources: preactive interview, video-recording…

By taking up the strand in Lave and Wenger's writing on situated learning that directs attention to social dynamics and issues of power and positioning, the present article argues for the fruitfulness of including the concept of negotiated participation in approaches to teaching and learning. Based on a fieldwork in vocational media production…

To chart the developmental path of children's attribution of pride to others, we presented children (4 years 0 month to 11 years 11 months of age, N = 108) with video clips of head-and-face, body posture, and multi-cue (both head-and-face and body posture simultaneously) expressions that adults consider to convey pride. Across age groups, 4- and…

The study explored the nature of the interactive play behaviours of children with albinism and children without albinism and compared the interactive behaviours of both children with albinism and children without albinism. Naturalistic observations were conducted during periods of free play, using the interactive play behaviour checklist aided by…

Kids and nature seem like a natural combination, but what was natural a generation ago is different today. Children are spending less time outdoors but continue to need nature for their physical, emotional, and mental development. This fact has led author Richard Louv to suggest that today's children are suffering from "nature-deficit disorder"…

Grading is one of the most enduring features of schooling. No matter what other reforms occur in a school, grading remains as one of the cornerstones of educational practice. But recently this long-standing tradition has come under scrutiny with some alarming results. Many traditional grading practices actually "depress" achievement, and may, in…

Two longitudinal studies examined associations between relational aggression and friendship quality during adolescence. In Study 1, 62 adolescents in Grades 6 (25.8%), 7 (32.3%), and 8 (41.9%) completed assessments of friendship affiliations, relational and overt aggression, and friendship quality at 2 time points, 1 year apart. Results using…

When discussing race in the classroom, getting students--including, importantly, white students--to see that all people have racial identities can be a challenge. This classroom exercise employs a rap video as a tool for helping to reveal white as a racial identity and for exploring the concept of white privilege--the idea that economic, social,…

Students may fear that they will feel unsupported and isolated when engaged in online learning. They don't know how they will be able to build relationships with their teacher and classmates solely based on written words, without facial expressions, tone of voice, and other nonverbal communication cues. Traditionally, online learning required…

Purpose: All-terrain vehicle (ATV) injury is an increasingly serious problem, particularly among rural youth. There have been repeated calls for ATV safety education, but little study regarding optimal methods or content for such education. The purpose of this study was to determine if an ATV safety video was effective in increasing ATV safety…

Imagery is a powerful sport psychology tool easily accessible to coaches. These reminders can help coaches improve their athletes' images and performance: (1) Create vivid and controllable images; (2) Use polysensory images and instructional cues, delivered, ideally, in real time; (3) Use internal and external perspectives; (4) Use imagery during…
