Surveying is a fundamental course in the Civil Engineering, Building Construction Management, Geomatics, Geography, Agriculture & Forestry, and Landscape Architecture curricula. Teaching surveying presents several challenges such as students' preparation in mathematics, geometry and trigonometry, limited access to instruments, limited availability to terrains on which to practice, dependency on weather conditions, and need for one-on-one training. This project enhances traditional surveying instruction methods with an engaging, interactive Virtual Environment for Learning Surveying (VELS) that can be integrated into surveying courses as a preparation, revision and assessment tool. The project uses innovative educational technologies that support students learning and lead to effective instructional approaches in the engineering curriculum. The VELS supports mathematical representational fluency and includes realistic virtual terrains and surveying instruments that look, operate and produce results comparable to the physical ones. The VELS solves many of the problems associated with the current surveying instruction; 1) it improves students' representation fluency in math by interconnecting concrete, numeric/symbolic, textual, pictorial, and real-world representations of mathematical, geometry and trigonometry concepts in the context of surveying, 2) provides 24/7 access to surveying equipment and practice exercises, 3) allows for surveying training at distance, 4) provides immediate feedback on student performance, 5) provides on-demand topic-specific guidance, 6) requires less dependency on team members, 7) provides access to standardized virtual equipment, and 8) provides instrument accessibility to students with motor and vision impairment.

测量学是土木工程、建筑施工管理、大地测量学、地理学、农林和风景园林等专业的一门基础课。测量学教学面临着几个挑战，如学生在数学、几何和三角方面的准备，获得仪器的机会有限，可用于练习的地形有限，对天气条件的依赖，以及需要一对一培训。该项目通过一个引人入胜的交互式虚拟测量学习环境(VELS)改进了传统的测量教学方法，该环境可作为准备、修改和评估工具整合到测量学课程中。该项目使用创新的教育技术来支持学生的学习，并在工程课程中引入有效的教学方法。VELS支持流畅的数学表示，包括逼真的虚拟地形和测量仪器，它们的外观、操作和产生的结果与物理仪器相当。VELS解决了与当前测量教学相关的许多问题；1)它通过在测量环境中连接具体的、数字/符号、文本、图形和真实世界的数学、几何和三角概念的表示来提高学生的数学表达流利性；2)24/7全天候访问测量设备和练习；3)允许远程测量培训；4)提供对学生表现的即时反馈；5)提供按需专题指导；6)减少对团队成员的依赖；7)提供对标准化虚拟设备的访问；以及8)为有运动和视力障碍的学生提供仪器访问。
