Paving Consensus: Enacting, Challenging, and Revising the Consensus Process in a Cohousing Community

This study focused on a cohousing community's use of consensus to make a decision about surfacing a parking area. It revealed that the community's use of consensus decision making allowed the residents to balance three goals: making an appropriate decision, meeting members' needs, and maintaining the community's well-being. Reaching agreement, however, was complicated by members' value differences and discontinuity in their participation. The analysis of this case reveals three qualities characteristic of the enactment of consensus: the role of structured communication within and between group meetings, a tension between maintaining process openness and reaching decision closure, and the expectation that group members will work within the consensus process. The analysis also highlights the importance of timing in the interpretation of conflict in a consensus-oriented group and the role of process change when a group reaches the limits of members' commitment to consensus.

Explaining match outcome in elite Australian Rules football using team performance indicators

The relationships between team performance indicators and match outcome have been examined in many team sports, however are limited in Australian Rules football. Using data from the 2013 and 2014 Australian Football League (AFL) regular seasons, this study assessed the ability of commonly reported discrete team performance indicators presented in their relative form (standardised against their opposition for a given match) to explain match outcome (Win/Loss). Logistic regression and decision tree (chi-squared automatic interaction detection (CHAID)) analyses both revealed relative differences between opposing teams for “kicks” and “goal conversion” as the most influential in explaining match outcome, with two models achieving 88.3% and 89.8% classification accuracies, respectively. Models incorporating a smaller performance indicator set displayed a slightly reduced ability to explain match outcome (81.0% and 81.5% for logistic regression and CHAID, respectively). However, both were fit to 2014 data with reduced error in comparison to the full models. Despite performance similarities across the two analysis approaches, the CHAID model revealed multiple winning performance indicator profiles, thereby increasing its comparative feasibility for use in the field. Coaches and analysts may find these results useful in informing strategy and game plan development in Australian Rules football, with the development of team-specific models recommended in future.

美国教师入职教育评价研究

自20世纪80年代以来,美国教师入职教育蓬勃发展,被视为初任教师进入教学专业场域的必经部分,并一致认同入职教育的展开与教师留任、教师效能有关。美国教师入职教育在各州、各学区的施行虽不尽相同,但由各州教育主管部门、以美国新教师发展中心为代表的非营利性机构研究机构所倡导的评价体系大多涉及以下内容:评价初任教师、导师、行政管理人员等参与对象;勾勒评估框架,评价入职教育项目的投入与产出、结果与成效等整体全貌;评价入职教育政策,对全美各州现行入职教育政策进行回归分析,提炼关键要素,拟定参考标准等。
