Web-Based Homework: Curriculum Reform Incorporating Drawings And Graphs

物理改革的努力正在改变课堂教学，但管理机制对家庭作业的影响有限。基于网络的家庭作业提供了部分解决方案，但受到可用回答类型的限制，学生的图画和图表尤其成问题。该项目正在创建一组灵活的、模块化的Java小程序，用于绘制简单的图形和图表。这些自我评分的小应用程序可以与大多数基于网络的作业系统以及标准的HTML页面一起使用，从而能够使用新的练习课。PI和本科生正在开发一套完整的练习，使用这些小程序在广泛使用的网络作业系统和HTML页中伴随标准的入门物理课程。该项目还在调查使用模式、困难来源和有效性，并将评估作为项目的一个组成部分。传播是通过互联网、网络作业系统、会议演讲和工作室。智力优势：这些小程序同时解决了物理课程改革努力和使用广泛可用的技术的网络作业的重大困难。广泛的影响：这些小程序具有明确的应用，从物理入门到数学、化学、工程和任何使用图形、矢量、表格和方程的领域。练习的提供有助于鼓励和帮助以传统方式授课的教师在课堂上融入更多基于研究的方法和活动。教师准备：作为未来高中物理教师的本科生是该项目不可或缺的一部分。

Physics reform efforts are changing classroom instruction, but administrative mechanics have had limited impact on homework. Web-based homework offers a partial solution, but is limited by types of responses available, and student drawings and graphs are especially problematic. This project is creating a set of flexible, modular Java applets for drawing simple graphs and diagrams. These self-grading applets can work with most web-based homework systems as well as standard HTML pages, enabling the use of new classes of exercises. The PI and undergraduate students are developing a complete set of exercises using these applets to accompany a standard introductory physics curriculum within a widely used web homework system and HTML pages. The project is also investigating usage patterns, sources of difficulties, and effectiveness with assessment as an integral part of the project. Dissemination is via the Internet, web-homework systems, conference talks, and workshops.Intellectual merit: these applets simultaneously solve significant difficulties with both physics curricular reform efforts and web-based homework using widely available technology.Broader impact: these applets have clear applications beyond introductory physics to math, chemistry, engineering and any areas where graphs, vectors, tables and equations are used. The availability of exercises can help to encourage and assist instructors who teach in a traditional style to incorporate more research-based methods and activities in their classroom.Teacher preparation: Undergraduate students who are future high school physics teachers are an integral part of this project.
