面积测量的概念被广泛认为是基本的。作为连续乘法量类的代表,它既具有内在的重要性,又具有重要的结构意义。因此,在具有意义和概念理解的情况下灵活运作是基础教育的一个重要目标。同时,学习者在面积方面遇到的困难在文献中有很好的记载,包括在可视化结构化的2D空间和概念化将两个长度量度转换为面积量度的指代转换动作方面的挑战。作为对这些挑战的回应,我们对他们的活动进行了分析,三年级的学习者通过扫描一段长度(一根橡皮刷)穿过另一段长度来生成具有面积的图形。我们描述了一组物理和虚拟学习环境,这些环境是我们开发的,用来实现这种全面的学习方法--我们还展示了这两个环境是如何支持课堂上的一群学生应对上述两个挑战的。在我们的分析中,我们借鉴了查尔斯·古德温的合作行动框架,展示了在个人和群体层面上,学习者如何开始围绕面积测量建立专业愿景,以及他们发展出的共同手势如何指向对面积作为一个动态数量的新兴集体理解。
The concept of area measure is widely viewed as fundamental. It is both intrinsically important and also structurally significant, as a representative of the class of continuous multiplicative quantities. Operating flexibly in this context with meaning and conceptual understanding is thus a critical objective for elementary education. Meanwhile, the difficulties learners encounter with area are well documented in the literature and include challenges with visualizing structured 2D space and conceptualizing the referent-transforming action that converts two length measures into area measure. Responding to these challenges, we present an analysis of their activity where third-grade learners generated figures with area by sweeping one length (a ‘squeegee’) through another length. We describe a ‘duo’ of physical and virtual learning environments that we developed to enable this ‘sweeping’ approach to area – and we show how this duo supported a classroom group of students in engaging with the two challenges mentioned above. In our analysis, we draw upon Charles Goodwin’s framework of co-operative action, showing how, at both individual and group levels, learners began to build professional vision around area measure and how the shared gestures they developed pointed toward emerging collective understanding of area as a dynamic quantity.
