Laboratory instruction is under siege because space, capital equipment funds, and faculty time are all in short supply. In response, computer simulations commonly replace hands-on laboratory experiences. Computer simulations are powerful tools, but they must be linked directly to physical phenomena if they are to teach the physical realities of engineering. The purpose of this project is to develop simulation software and matched experiments that will enable students of statics and mechanics of materials courses to conduct side-by-side, real time comparisons of Analytical and Experimental results of small-scale model tests in a portable, PC-controlled laboratory called "ANNEX." ANEX has been developed and implemented successfully in junior-level structural analysis courses at UMR and the University of Michigan at Ann Arbor. Newly developed software and matched experiments (called "MECH-ANEX") will extend ANEX to address a broader audience of lower-division undergraduates, thus increasing the utility of ANEX stations and the probability that ANEX will make a national impact on undergraduate laboratory instruction. MECH-ANEX software will include lecture reinforcement and case study modules tailored to several engineering disciplines that typically require statics and mechanics of materials courses in their curricula. In addition, a complete set of matched, bench-scale experiments will be developed. MECH-ANEX will be integrated into the UMR curriculum, assessed over a multi-semester trial period, and presented in a series of national seminars and workshops. This project will produce an innovative model for lecture and laboratory integration with potential applications across the engineering and science disciplines.

由于空间、资本设备资金和教师时间都短缺，实验室教学受到围攻。作为回应，计算机模拟通常取代实验室实践经验。计算机模拟是强大的工具，但如果要教授工程的物理现实，它们必须与物理现象直接联系起来。 该项目的目的是开发仿真软件和匹配实验，使材料静力学和力学课程的学生能够在名为“ANNEX”的便携式 PC 控制实验室中对小规模模型测试的分析和实验结果进行并排实时比较。 ANEX 已在 UMR 和密歇根大学安娜堡分校的初级结构分析课程中成功开发和实施。新开发的软件和配套实验（称为“MECH-ANEX”）将扩展 ANEX，以适应更广泛的低年级本科生受众，从而提高 ANEX 站的实用性以及 ANEX 对本科生实验室教学产生全国性影响的可能性。 MECH-ANEX 软件将包括针对多个工程学科量身定制的讲座强化和案例研究模块，这些学科通常需要在课程中包含静力学和材料力学课程。此外，还将开发一整套匹配的小型实验。 MECH-ANEX 将纳入 UMR 课程，在多个学期的试用期内进行评估，并在一系列国家研讨会和讲习班中进行介绍。该项目将产生一个创新模型，用于讲座和实验室集成，并具有跨工程和科学学科的潜在应用。
