摘要

当利用基本的描述性统计为真实问题建立数学模型时,许多一年级工程专业的学生在适当的时候没有处理数据分布。与这样一个问题相关的作业是创建的,它要求学生开发他们自己的测试用例,作为让学生更深入地思考所提供的数据和他们正在开发的模型的一种手段。在进行中的工作中,将分析这些测试用例。测试用例的均值和标准偏差与提供给问题的那些完全不同。然而,有证据表明,学生可能没有注意到原来的问题背景。简要说明了接下来的步骤。

Work in progress: First-year engineering students development of test cases for model development
When developing mathematical models for authentic problems that draw on basic descriptive statistics, many first-year engineering students do not address data distribution when it is appropriate to do so. An assignment was created in association with such a problem that asks students to develop their own test cases as a means of getting students to think more deeply about the data provided and the models they are developing. In this work in progress, these test cases are analyzed. The means and standard deviations of the test cases are quite different than those provided with the problem. However, there is evidence that students may not be attending to the original problem context. Next steps are briefly indicated.
