The IDEA-Pen project is using tablet technology to provide a means of helping students perform engineering analysis problems in a classroom environment. Using an electronic pen, students will be able to sketch structural analysis problems. Image analysis software previously written by the investigators is used to pass the sketch to a Finite Element Analysis (FEA) program. The FEA program will then provide analysis of the sketch made by the students. Student learning is expected to increase because they will be able to explore several options for design (increase the design space) since the analysis can be done quickly. By increasing the design space, students will be able to observe the effects that design changes have on the performance of their design. This will increase intuition about system performance and will result in better design skill. This outcome is being monitored by analyzing student performance on exams. It is also expected that the technology will help shift the classroom from a teacher centered to a student centered environment. This expectation is being monitored by analyzing the number and variety of problems attempted that are not assigned by the instructor. Classrooms are expected to become more interactive and certainly more engaging for the students. This expectation is monitored by directly measuring the numbers of problems attempted by students. Widespread dissemination of the project results are expected to occur because the software will be provided in an open source format and could be distributed through popular application downloads centers.

IDEA-Pen项目利用平板电脑技术帮助学生在课堂环境中进行工程分析问题。使用电子笔，学生将能够画出结构分析问题的草图。使用先前由调查人员编写的图像分析软件将草图传递给有限元分析（FEA）程序。然后，FEA程序将对学生所做的草图进行分析。学生的学习预期会增加，因为他们将能够探索几个设计选项（增加设计空间），因为分析可以快速完成。通过增加设计空间，学生将能够观察到设计变化对其设计性能的影响。这将增加对系统性能的直觉，并将导致更好的设计技能。这一结果是通过分析学生的考试成绩来监测的。预计该技术将有助于将教室从以教师为中心转变为以学生为中心的环境。这种期望是通过分析教师没有布置的问题的数量和种类来监测的。课堂应该变得更加互动，对学生来说当然也更有吸引力。这种期望是通过直接测量学生尝试的问题数量来监控的。由于该软件将以开放源代码的形式提供，并且可以通过流行的应用程序下载中心分发，因此预计项目结果将得到广泛传播。
