CELTIC: Calculus for ELementary Teachers: an Innovative Context

这个项目开发、试验、分析和改进了一系列任务和活动，这些任务和活动构成了专门为基础教育专业设计的两学期微积分序列的第一学期，并取代了目前的小学数学本科课程。微积分不仅是数学的基础，对其他STEM领域也是如此，因此学习微积分对于这个专注于STEM的新品牌小学教师来说很重要。这门面向小学专业的微积分课程是为了满足国家对培养懂STEM的小学教师的需要。未来的小学教师也需要对小学数学有深刻的理解，这个项目将微积分与小学数学联系起来，这是必要的和重要的联系。为此，北卡罗来纳州立大学数学系、数学教育系和基础教育系的教育工作者开发了一套材料，作为这门创新微积分课程的基础和小学教师的教科书。在进行这一发展的过程中，对材料的实地测试和对教师学习情况的评估决定了这一耐人寻味的假设的有效性。

This project develops, pilots, analyzes, and refines a set of tasks and activities that make up the first semester of a two semester calculus sequence designed specifically for elementary education majors and replaces the current elementary mathematics undergraduate courses. Calculus is foundational not only to mathematics, but to other STEM areas as well, so learning calculus is important for this new brand of STEM-focused elementary teachers. This Calculus for Elementary Majors serves the nation's need to educate elementary teachers who know STEM. Future elementary teachers also need a profound understanding of elementary mathematics and this project makes necessary and important connections between calculus and elementary school mathematics. To do this, educators in the mathematics department, mathematics education department, and elementary education department at NC State developed a set of materials that serve as the basis for this innovative calculus course and a textbook for elementary teachers. In the process of conducting this development, field testing of the materials and assessment of the learning of the preservice teachers determined the validity of this intriguing hypothesis.
