本研究探讨了13名准中学数学教师开发和验证函数作为现实世界情境数学模型的策略。学生们选修了一门数学课程，可以不断地使用曲线筛选器、绘图工具和其他计算工具。建模方法分为4个技术使用的一般类别，通过曲线筛选器使用的范围和性质以及影响模型开发和评估的数学与现实的相对主导地位来区分。数据表明，策略选择受到任务特征和与其他学生建模者的互动的影响。提出了策略选择和使用的假设。
This study explored the strategies used by 13 prospective secondary school mathematics teachers to develop and validate functions as mathematical models of real-world situations. The students, enrolled in an elective mathematics course, had continuous access to curve fitters, graphing utilities, and other computing tools. The modeling approaches fell under 4 general categories of technology use, distinguished by the extent and nature of curve-fitter use and the relative dominance of mathematics versus reality affecting the development and evaluation of models. Data suggested that strategy choice was influenced by task characteristics and interactions with other student modelers. A grounded hypothesis on strategy selection and use was formulated.
