Objective: The authors provide examples for the use of the WebCam as a therapeutic tool in child psychiatry, discussing cases to demonstrate the application of the WebCam, which is most often used in psychiatry training programs during resident supervision and for case presentations. Method: Six cases illustrate the use of the WebCam in individual…

A simple spectrophotometer was designed using cardboard, a DVD, a pocket digital camera, a tripod and a computer. The DVD was used as a diffraction grating and the camera as a light sensor. The spectrophotometer was calibrated using a reference light prior to use. The spectrophotometer was capable of measuring optical wavelengths with a…

The study describes an adapted form of "interactive writing" (McCarrier, Pinnell, & Fountas, 2000) and examines its effectiveness as an approach to beginning writing instruction for young children who are deaf or hard of hearing. Systematic videotape analysis was used to document the content of 45 adapted interactive writing lessons across an…

There has been little research on academic writers that shows how social interaction influences the construction of "discoursal identity" (the impressions that writers convey about themselves in their texts and that readers develop about writers). This study analyzes a collaborative writing session among college students to explore the negotiation…

The present article focuses on in situ social comparison among junior high school students. Rather than studying social comparison as an individual phenomenon in experimental situations, which has been common in previous research, the study analyzes social comparison as a real-life social practice. The results show that the practice of social…

Although researchers have reported positive effects on teacher learning from observing published video, teachers' own video, and their colleagues' video, very few professional development programs have integrated all three types of video to improve teacher learning. In this study, we examined the affordances and challenges of the three types of…

In this article, the authors introduce a new conceptual tool, intimate technology, to mobilize social work students' commitment to anti-racism. Intimate technology is marked by its emotional intensity and accessibility, and its effect of de-centering knowledge and authority. This teaching strategy integrates the modality of intimate technology via…

This study investigated students' activating positive affective experiences in mathematics lessons, their antecedents, their cognitive and motivational consequences, as well as their effect on achievement. The participants were 682 Grade 8 and 9 students from 37 classes from Germany and Switzerland who participated in a video study of lessons on…

This study investigates how accurate one item writer can be on item difficulty estimates and whether factors affecting item writer judgments correspond to predictors of actual item difficulty. The items were based on conversational dialogs (presented as videos online) that focus on pragmatic functions. Thirty-five 2nd-, 3rd-, and 4th-year learners…

Web 2.0 technologies can be considered a loosely defined set of Web application styles that foster a kind of media consumer more engaged, and usually active in creating and maintaining Internet contents. Thus, Web 2.0 applications have resulted in increased user participation and massive user-generated (or user-published) open multimedia content,…

This study explores the extent to which a teacher elicited students' mathematical reasoning through the use of challenging tasks and the role her knowledge played in doing so. I characterised the teacher's knowledge in terms of a "local theory" of instruction, a form of pedagogical content knowledge that involves an empirically tested set of…

Prior studies have indicated brain abnormalities underlying social processing in autism, but no fMRI study has specifically addressed the differential processing of direct and averted gaze, a critical social cue. Fifteen adolescents and adults with autism and 14 typically developing comparison participants viewed dynamic virtual-reality videos…

This is a two-part discussion. Part 1 is entitled "English Language Learning in Subject Lessons", and Part 2 is titled "Video as a Research Tool/Counterpoint". Working with different research concerns, the authors attempt to draw attention to a set of methodological and theoretical issues that have emerged in the research process using video data.…

The perceived relation between assigned student grades and instructor evaluations of teaching has been the subject of much debate, though few laboratory studies have been conducted with adequate controls. Marsh and Roche suggested that experimental field studies may be a particularly promising avenue for further analyses of this relation. The…

The quality of measurement systems used in almost all natural sciences other than behavior analysis is usually evaluated through calibration study rather than relying on interobserver agreement. We demonstrated some of the basic features of calibration using observer-measured rates of free-operant responding from 10 scripted 10-min calibration…
