9351910 Rogers We have acquired a scanning tunneling microscope (STM) for use by undergraduates in supervised laboratory course work, in classroom demonstrations and for scheduled use in undergraduate independent research projects. The STM offers new and dramatically better ways to introduce students to the physics of materials and to the basic quantum mechanical nature of our world. However, because the STM technique is quite new, its use in physics and chemistry courses is extremely rare. We are harnessing the instructional potential of STM by integrating it into our undergraduate curriculum. We are initially implementing this plan in three specific ways. First, we introduce a set of quantitative STM experiments for use in our senior level experimental laboratory course. We are designing a laboratory section in which the students explore quantum mechanical tunneling and learn how it can be used to study the properties of materials. Second, we are developing two classroom demonstrations which use the STM to illustrate the atomic structure of surfaces and molecules respectively. Third, we are tapping the potential of STM for high quality hands-on research experience for undergraduates by scheduling the use of the STM for undergraduate independent research projects. We believe that it is important to bring modern research results into the classroom as soon as it is practical to do so. We are integrating the new field of molecular imaging and manipulation into our curriculum to give students a more concrete understanding both of our physical world and the fundamental principles underlying modern technology. ***

9351910罗杰斯我们已经获得了一个扫描隧道显微镜（STM）的本科生在监督实验室课程工作中使用，在课堂演示和本科生独立研究项目中预定使用。 STM提供了新的和更好的方法来向学生介绍材料物理和我们世界的基本量子力学性质。 然而，由于STM技术是相当新的，它在物理和化学课程中的使用是非常罕见的。 我们正在利用STM的教学潜力，将其整合到我们的本科课程。 我们将从三个具体方面初步实施这一计划。 首先，我们介绍了一套定量STM实验，用于我们的高级实验室课程。 我们正在设计一个实验室部分，让学生探索量子力学隧道，并学习如何将其用于研究材料的特性。 其次，我们正在开发两个课堂演示，分别使用STM来说明表面和分子的原子结构。 第三，我们正在挖掘STM的潜力，为本科生提供高质量的实践研究经验，安排STM用于本科生独立研究项目。 我们认为，重要的是尽快将现代研究成果带入课堂。 我们正在将分子成像和操作的新领域整合到我们的课程中，让学生更具体地了解我们的物理世界和现代技术的基本原理。 ***
