We investigate the stability and change of participation patterns in small groups by examining two longitudinal data sets at the individual and group levels of analysis. Rejecting the dichotomy between input and process models, we advance a view at the convergence of these two perspectives. We argue that stability in participation reflects input factors and that change emerges from process mechanisms. Study 1 analyzed discussion data from zero-history laboratory groups that worked on three similar tasks in succession, each with stable membership across the tasks. Results showed significant variation within participants and between groups, indicating that group members varied their participation as needed and that group-level factors influenced participation. Study 2 analyzed longitudinal data collected from the Australian Citizens' Parliament, where tasks and group membership varied over time. Study 2 replicated Study 1's findings, but analyses showed more complex patterns of both stability and change across groups and tasks. Taken together, results from the two studies support our position that both input and process mechanisms cause variation in participation. Our Conclusion examines how structural features and participation impact democratic group deliberation.  相似文献

The long‐term import of a fundamental challenge of adolescent social development—establishing oneself as a desirable peer companion while avoiding problematic behaviors often supported within peer groups—was examined in a community sample of 184 adolescents, followed from ages 13 to 23, along with parents, peers, and romantic partners. The dialectical nature of this challenge appeared in findings that autonomy vis‐à‐vis peer influences predicted both long‐term success avoiding problematic behavior but also more difficulty establishing strong adult friendships. Conversely, being a desirable peer companion in adolescence predicted more positive adult relationships but also greater alcohol use. Adolescents who established themselves as both desirable companions and as autonomous vis‐à‐vis peers were rated as most successful by their parents at age 23.  相似文献

Student behavioral engagement is a key condition supporting academic achievement, yet student disengagement in middle and high schools is all too common. The current study used a randomized controlled design to test the efficacy of the My Teaching Partner‐Secondary program to increase behavioral engagement. The program offers teachers personalized coaching and systematic feedback on teachers’ interactions with students, based on systematic observation of videorecordings of teacher‐student interactions in the classroom. The study found that intervention teachers had significantly higher increases, albeit to a modest degree, in student behavioral engagement in their classrooms after 1 year of involvement with the program compared to the teachers in the control group (explaining 4% of variance). In exploratory analyses, two dimensions of teachers’ interactions with students—their focus on analysis and problem solving during instruction and their use of diverse instructional learning formats—acted as mediators of increased student engagement. The findings offer implications for new directions in teacher professional development and for understanding the classroom as a setting for adolescent development.  相似文献

This self-study explores the emerging identity of a first-time teacher educator using a framework that views identity as natural, institutional, discursive, and affinity. This framework provided an opportunity to unpack empirically how these various strands of identity intersected within the classroom of a novice teacher educator. Situated in the context of an elementary social studies methods classroom, this study reveals various struggles with the institutional authority of being a teacher educator. Issues such as how preservice teachers perceive a novice teacher educator, the acknowledgment of lack of experience, and the process of negotiating institutionalized and systemic power within the classroom are discussed. Because this study also featured a mentor professor as a critical friend, the implications of self-study work and mentoring first-time teacher educators are also featured in the discussion section. Considering the importance of identity in shaping the practice of new teachers, this self-study reveals the importance of further complicating the emerging and evolving identities of new teacher educators.  相似文献
