在这项研究中，我们使用了一个设计环境，通过设计，建造，测试和评估模型来发展儿童对自然世界的理解。在这个例子中，我们让孩子们设计人类肘部的模型。儿童的模型，然后被用来作为人类手臂的生物力学探索的基础。生物力学原理的调查是我们早期研究的一个主要延伸。通过建立在儿童的设计为基础的模型，我们能够让学生参与调查的力量和二头肌附着点的位置之间的关系。在这样做时，我们能够为儿童提供机会，通过构建和解释数据表和图表，发展他们对数学和科学之间关系的理解。设计是一种解决问题的形式，其中思维，工具操作和材料反映在人工制品的构造中（Bucciarelli，1994; Roth，1996; Simon，1981）。反过来，人工制品成为促进知识共享的对象。此外，由于许多设计问题，至少在最初，本质上是不确定的，问题解决者必须首先定义问题，然后明确地陈述和证明问题和建议的解决方案之间的关系。这促进了一种知识的观点，即有目的的，流动的和有条件的（Lehrer，1993）。在这项研究中，我们使用了一个设计环境，通过设计，建造，测试和评估模型来发展儿童对自然世界的理解。我们选择了一个设计的重点，因为设计的过程为儿童提供了构建，应用，辩论和评估模型的潜力，而不是简单地
In this study, we used a design context for developing children's understanding of the natural world via the designing, building, testing, and evaluation of models. In this instance, we asked children to design models of the human elbow. Children's models were then used as the basis for an exploration of the biomechanics of the human arm. The investigation of biomechanical principles is a major extension of our earlier research. By building on children's design-based models, we were able to engage students in an investigation of the relation between force and the location of the attachment point of the biceps. In so doing, we were able to provide children with opportunities to develop their understanding of the relations between mathematics and science through the construction and interpretation of data tables and graphs. Design is a form of problem solving in which thinking, tool manipulation, and materials are reflected in the construction of an artifact (Bucciarelli, 1994; Roth, 1996; Simon, 1981). In turn, artifacts become objects that facilitate the sharing of knowledge. Moreover, because many design problems are, at least initially, inherently unspecified, the problem solver must often first define the problem and then explicitly state and justify the relation between the problem and the proposed solution. This promotes a view of knowledge as purposeful, fluid, and conditional (Lehrer, 1993). In this study, we used a design context for developing children's understanding of the natural world via the designing, building, testing, and evaluation of models. We chose a design focus because the process of design affords the potential for children to construct, apply, debate, and evaluate models, rather than to simply
