Qualitative Differences Between Learning Environments Using Videos in Small Groups and Whole Class Discussions: A Preliminary Study in Physics

Interactivity, group learning and student engagement are accepted as key features of social constructivist learning theories. The challenge is to understand the interplay between such features in different learning environments. This study focused on the qualitative differences between two interventions—small-groups and whole-class discussions. In both interventions, three short video slices on the abstract topic ‘the physics of superconductivity’ were interspersed with the different discussion styles. The video slices are based on the Bruner stages. Twenty-nine first year university physics students completed a pre-test, underwent the intervention and completed a post-test. The remainder of the data were collected from student drawings, video recordings, observer notes and facilitator feedback. Results indicate that the use of the video slices in both interventions were successful in changing students’ understandings of superconductivity. However, the small groups treatment tended to facilitate questioning, meaning-making and subsequent changes of ideas more so than the whole class discussions. Implications for research and practice are discussed.

同步录音录像制度的功能、问题与期待

同步录音录像具有规范侦查取证、保障公民权利、证明取证合法以及增强办案能力的制度功能,但新刑事诉讼法中有关同步录音录像的规定比较笼统,实践中选择性录音录像成最大难题。现阶段有必要鼓励对所有刑事案件进行录音录像、对“全程录制”进行严格界定与执行,同时规范同步录音录像的相关操作程序,并在实践中探索同步录音录像实施的制度性保障。

Affordances of using Multiple Videoed Events to construct a rich understanding of adult–child book readings

This paper explores the affordances of using video-based research to capture a multiplicity of events, along with multimodal representations when producing data related to adult–child book readings. In doing this we answer two questions: (1) why more than one event is needed when seeking a comprehensive collection of information for the purpose of analysis; and (2) why one mode of data production alone (e.g. audio recordings or note taking) is insufficient to record practice or interviews when richness is of priority. This research used three videoed events to produce data. These included videoing: (1) caregiver–child interactions during four shared book reading sessions, (2) interviews with caregivers immediately following each of the reading sessions and (3) video-stimulated discussions with caregivers within two months of the final shared book reading. In this paper, I contribute to discussions that highlight the affordances of using video-based research as a means of capturing the multimodal elements of an experience, which can contribute to the analysis and interpretation of data. I expand on this, however, to suggest that when coupled with a multiplicity of events, video-based research can be a means of pursuing richness via a method that has been criticized for its narrow subjectivity.     

“It Lets Me Fight the Bad Guys”: An Exploration Into the Factors Predicting Enjoyment of Violent Video Games

In an exploratory survey that sampled video gamers, participants were asked to indicate why they enjoy playing their favorite video game. On the basis of ESRB ratings, we compare those whose favorite game is violent to those whose favorite game is nonviolent. Consistent with self-determination theory, the findings suggest need for autonomy and competence are important motivating factors. However, the findings also suggest fans of violent games differed from fans of nonviolent games in the degree to which arousal, liking violence, playing the vicarious hero, and playing the vicarious villain drive enjoyment. Furthermore, being able to play the hero and “fight bad guys” was a significant predictor of enjoyment of violent games. Implications for self-determination theory and theories of media enjoyment are discussed.
