CELTIC: Calculus for ELementary Teachers: an Innovative Context

本项目开发、试点、分析和完善了一套任务和活动，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，并取代了目前的基础数学本科课程。微积分不仅是数学的基础，也是其他STEM领域的基础，所以学习微积分对这些专注于STEM的新一代小学教师来说很重要。《小学专业微积分》满足了国家教育懂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，这个项目在微积分和小学数学之间建立了必要而重要的联系。为此，北卡罗来纳州立大学数学系、数学教育系和小学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，也是小学教师的教科书。在进行这一开发的过程中，对材料的实地测试和对职前教师学习的评估确定了这一有趣假设的有效性。

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.
