资源理论中的一个问题是描述新的、高水平的资源的创造。我们通过分析四个学生小组在关于空气阻力的集体测验中分离变量来模拟资源创建。我们评估每个小组的流利性和两个可观察性:使用公开的(如除法、减法、等于)和隐蔽的(如移动、带来或靠边)数学语言,以及使用伴随的手势(如绕圈、抓取或滑动)。对于每一组,使用的语言和手势的类型对应于他们进行变量分离的容易程度。我们为每个组创建资源图来组织我们的观察,并使用这些图来对程序资源分离变量的创建进行建模。
A problem in resource theory is describing the creation of new, high‐level resources. We model resource creation by analyzing four student groups separating variables during a group quiz on air resistance. We assess each group’s fluency and two observables: use of overt (such as divide, subtract, equals) and covert (such as moving, bringing, or pulling over) mathematical language and use of accompanying gestures (such as circling, grabbing, or sliding). For each group, the type of language and gesture used corresponds to how easily they carry out separation of variables. We create resource graphs for each group to organize our observations and use these graphs to model the creation of the procedural resource Separate Variables.
