Enhancing Mathematics Communication: Creating and Delivering Web-based Homework Problems

数学科学（21）。本项目正在调整和实施一个基于网络的家庭作业分发系统WQS，该系统由肯塔基大学（英国）在美国国家科学基金会资助下创建（du -99542436）。首先，WQS被用来提供大学代数、第一学期微积分、第一学期微积分实验室和商业微积分的大量家庭作业问题。这些材料为在某些先决主题上技能薄弱的学生提供帮助，以及在新的课程主题上提供帮助。其次，该项目改编了英国为未来高中数学教师开发的问题解决课程，学生使用Maple设计基于网络的问题，并通过WQS将其发布到网络上。最后，pi正在为大学教师和现任高中教师举办学年和夏季研讨会，以设计基于网络的问题，并与他们自己的学生一起使用WQS。评估包括多次学生和教师调查和比较研究，通过衡量教师和学生之间的沟通，学生之间的合作以及学生表现的改善来确定WQS对学生在大学课程中的价值。

Mathematical Sciences (21). This project is adapting and implementing a web-based homework delivery system, WQS, created at the University of Kentucky (UK) under NSF funding (DUE-99542436). First, WQS is being used to deliver extensive sets of homework problems in college algebra, first term calculus, first term calculus lab, and business calculus. The materials are providing assistance for students with weak skills in certain prerequisite topics, as well as help on new course topics. Second, the project is adapting a problem-solving course developed at UK for prospective high school mathematics teachers in which students use the Maple to design web-based problems, posting them on the web via WQS. Finally, the PIs are conducting academic year and summer workshops for college faculty and current high school teachers to design web-based problems and use WQS with their own students. Assessment includes multiple student and faculty surveys and comparative studies to determine the value of WQS for students in university courses by measuring communication between faculty and students, collaboration among students, and improvements in student performance.
