Instructional design is the theory surrounding how learners perceive information and is prevalent in simulation-based medical education. Simulation is used for a variety of medical procedures including central venous catheterization (CVC). The dynamic haptic robotic trainer (DHRT) is a CVC teaching simulator developed to specifically focus on training the needle insertion portion of CVC. While the DHRT has been validated to teach CVC as well as other training methods, an opportunity was seen to redesign the instructions of the DHRT to increase the learnability of the system. A hands-on instructional walkthrough was designed. A group trained with the hands-on instructions was compared to a previous group to assess initial insertion performance. Results indicate that changing the instructional method to be hands-on may have an impact on system learnability and help reinforce development of core components of CVC.
教学设计是关于学习者如何感知信息的理论，在基于模拟的医学教育中很普遍。模拟被用于包括中心静脉置管（CVC）在内的各种医疗程序。动态触觉机器人训练器（DHRT）是一种专门为训练CVC的针头插入部分而开发的CVC教学模拟器。虽然DHRT已被证实与其他训练方法一样能教授CVC，但人们发现有机会重新设计DHRT的操作指南，以提高该系统的易学性。设计了一个实际操作的教学演练。将一组接受实际操作指南培训的人员与之前的一组人员进行比较，以评估初始插入操作的表现。结果表明，将教学方法改为实际操作可能会对系统的易学性产生影响，并有助于加强CVC核心组件的开发。
