This project combines hands-on experiential discovery laboratory exercises with computer-aided instruction into computer aided laboratory instruction (CALI). The goal of the project is to enhance laboratory learning and understanding while significantly reducing the time, equipment, staffing and space requirements. A generalized, interactive software application is being developed which presents the laboratory problem, guides students through setup of the experiment and physical apparatus, monitors the experimental effort, provides feedback during the laboratory exercise, and evaluates student performance. An existing prototype CALI experiment is being modified, based on experience to date, and two new experiments are being developed. The efficacy of the CALI system is being evaluated by having randomly selected experimental groups perform the CALI experiments and comparing their short and long term learning with control groups performing conventional laboratory experiments with similar apparatus without the CALI interface. This evaluation procedure is being replicated at another institution for one of the experiments. Resources are being tracked to estimate potential savings. CALI details and the evaluation results will be disseminated by conference presentations and through testing of the system at the second institution.

该项目结合动手体验发现实验室练习与计算机辅助教学到计算机辅助实验室教学（卡利）。该项目的目标是加强实验室学习和理解，同时大幅减少时间、设备、人员配置和空间需求。 一个广义的，交互式的软件应用程序正在开发，提出了实验室的问题，引导学生通过设置的实验和物理仪器，监测实验的努力，在实验室练习提供反馈，并评估学生的表现。 根据迄今为止的经验，正在修改现有的卡利实验原型，并正在开发两个新的实验。 通过随机选择实验组进行卡利实验，并将其短期和长期学习与对照组进行常规实验室实验（使用没有卡利接口的类似设备）进行比较，来评估卡利系统的功效。 另一个机构正在为其中一项实验复制这一评估程序。 正在跟踪资源，以估计可能的节省。 卡利的详细情况和评价结果将通过会议介绍和在第二个机构测试该系统来传播。
