Dashboards have been hypothesized to facilitate adaptive guidance in classrooms. Thus far, however, empirical studies in this domain are badly missing. We present a dashboard, which enables teachers to observe concurrent groups as they engage in mathematical tasks using Dynamic Geometry tools and to guide groups when their intervention is needed. We rely on a case study with this dashboard in which a single teacher could successfully orchestrate the progression of several groups working on difficult problems in geometry, when being sent realtime alerts about critical moments, moments whose occurrence may impinge on further co-construction of knowledge. In the present study, we chose six 20-min long demo videos of small groups in a variety of sessions of unguided group work, where each video describes the work of one of six small groups (dyads or triads) dealing simultaneously with identical set tasks. Two versions of this demo were prepared, one with alerts of critical moments generated according to predefined rules, and the other without alerts. The teachers observing concurrent groups and being updated about critical moments (N1 = 21) better understand progression in groups than teachers that are not informed about these critical moments (N2 = 18). In a second study we found that the dispatching of alerts impinges on the ways the teachers navigate across rooms. In particular, they pay attention to certain alerts and at the same time, focus on learning processes in mathematics. We conclude that such tools may help bringing collaborative settings more often in classrooms.

数学教室中的协作学习:教师能否理解并发协作小组的进度?

假设仪表板可促进教室中的适应性指导。然而,到目前为止,在这一领域的实证研究严重缺失。我们提供了一个仪表板,该仪表板使教师能够在使用动态几何工具进行数学任务时观察并发的小组,并在需要干预时指导小组。我们依靠此仪表板的案例研究,在该仪表板中,一位老师可以成功地协调几个小组讨论几何难题的进度,向他们发送有关关键时刻的实时警报,这些时刻的发生可能会影响知识的进一步共建。在本研究中,我们选择了6个20分钟长的小型演示视频,这些视频是在无人指导的小组工作中进行的,每个视频都描述了六个小组(二重奏或三重奏)之一同时处理相同的设定任务的工作。准备了该演示的两个版本,一个版本具有根据预定义规则生成的关键时刻警报,另一个版本没有警报。与不了解这些关键时刻的老师(N2 = 18)相比,观察并发组并了解关键时刻(N1 = 21)的教师更好地了解了小组的进步。在第二项研究中,我们发现警报的分配会影响教师在教室中导航的方式。他们特别注意某些警报,同时专注于数学学习过程。我们得出的结论是,此类工具可能有助于在教室中更频繁地带来协作设置。
