Metacognitive activity in the physics student laboratory: is increased metacognition necessarily better?

In this study natural-in-action metacognitive activity during the student laboratory in university physics is explored, with an aim towards quantifying the amount of metacognition used by the students. The study investigates whether quantifying natural-in-action metacognition is possible and valuable for examining teaching and learning in these contexts. Video recordings of student groups working during three types of introductory physics laboratories were transcribed and then coded using a coding scheme developed from related research on mathematical problem solving. This scheme identifies a group’s general behaviour and metacognitive activity. The study recognizes that reliably identifying metacognition is challenging, and steps are taken to improve reliability. Results suggest that a greater amount of metacognition does not appear to improve students’ success in the laboratory—what appears to matter is whether the metacognition causes students to change behaviour. This study indicates that it is important to consider the outcome of metacognition, not just the amount.

Two-year follow-up study of cognitive behavioral therapy for sexually abused children suffering post-traumatic stress symptoms

OBJECTIVE: The present study sought to determine whether the 12-session pre- to posttest therapeutic gains that had been found by Deblinger, Lippmann. and Steer (1996) for an initial sample of 100 sexually abused children suffering posttraumatic stress disorder (PTSD) symptoms would be sustained 2 years after treatment. METHOD: These sexually abused children, along with their nonoffending mothers, had been randomly assigned to one of three cognitive-behavioral treatment conditions, child only, mother only, or mother and child, or a community comparison condition, and were followed for 3 months, 6 months, 1 year, and 2 years after treatment. RESULTS: A series of repeated MANCOVAs, controlling for the pre-test scores, indicated that for the three measures of psychopathology that had significantly decreased in the original study (i.e., externalizing behavior problems, depression, and PTSD symptoms), these measures at 3 months, 6 months, 1 year, and 2 years were comparable to the posttest scores. CONCLUSIONS: These findings suggest that the pre- to post-treatment improvements held across the 2-year follow-up period. The clinical and research implications of these findings are discussed.     

An exploratory study into the complexity of relations between physics lecturers’ crafting of practice and students’ expectations of quality teaching

This study contributes to research that characterises the affective learning that is evoked and taken on by students in response to their perceptions of their contextual learning environments. Interview-discussions were held with lecturers of both introductory and higher-level physics courses (n = 3) concerning how they formulated their patterns of teaching in terms of a particular conceptual framing that they considered to best optimize making learning possible. Subsequently their students (n = 212) were asked with written questions, and some select follow-up interview-discussions, to describe what they expected from ‘a good physics lecturer’. The relationships between these two things—the lecturer’s crafting of practice and the students’ expectations of quality teaching—were investigated. Results show that students’ expectations tend to match their lecturers’ practice, indicating that students are strongly influenced by a contextually based appreciation of ‘good’ teaching.

Boys to Men: Age,Identity, and the Legitimation of Amateur Wireless in the United States, 1909–1927

Although amateur radio remained popular for 100 years, it faced a crisis of legitimacy during the 1910s. The damaging behaviors of some operators threatened amateurs with banishment from the airwaves. Through an analysis of archival material from various sources, this paper demonstrates that in order to distance themselves from the actions of malevolent pranksters, responsible wireless operators tapped into contemporary cultural debates about maturity and the emergence of adolescence. As a result, amateur operators legitimated themselves in the eyes of the public while carving out a distinct space for youth hobbyists.
