The Lehigh Gap Story: A Design Partnership for Developing an Immersive Virtual Reality Field Trip

We established a designed partnership that includes Lehigh University faculty, students, and Lehigh Gap Nature Center staff to design and develop an immersive virtual field trip (iVFT) to enable people to understand the environmental changes that occurred in the Lehigh River Watershed in Pennsylvania during the past two centuries as a result of the zinc smelting plant operation at the Lehigh Gap. A green mountainous ridge became a barren “moonscape” as a result of zinc smelting activities that began in the 1890s. The smelting plant emitted approximately 3,450 pounds of sulfur per hour from 1918 to 1970, along with heavy metals, into the atmosphere. These pollutants produced acid rain and spread over the surrounding landscape. Five years after the smelting plants ceased operations, a comprehensive and laborious revegetation project was initiated by the U.S. Environmental Protection Agency and a local community group. The Lehigh Gap is revitalized today through a mixture of warm season grasses that have trapped the heavy metals in the soil. Today, the site includes a 756-acre wildlife refuge and the Lehigh Gap Nature Center, which is used for education, research, and outdoor recreation. Our iVFT tells this story through immersive experiences. Our design includes a virtual hike in the refuge through a series of 360° photospheres, animations, and assets to allow learners of all ages to experience historical events and geographical landmarks that are difficult to access or are no longer readily available. In addition, users learn about the construction and operations of historical transportation systems in the area (railroads and canals along the Lehigh River). Our session presents the iVFT and discusses important considerations for creating effective design partnerships among non-formal educators and university faculty.


Please Remain Seated: Large Classroom Virtual Field Trips with and Without 360° Headsets

Field trips are a pedagogical cornerstone of the natural sciences and are particularly effective at developing deep learning skills (e.g., critical thinking). They promote student enjoyment and as such, facilitate long-term knowledge retention. However, field trips require considerable logistical planning, present significant health and safety concerns and are often associated with prohibitive financial costs for students. The concept of “virtual” field trips has emerged as an alternative option to traditional site visits. Virtual field trips can provide a more inclusive experience for students that are financially burdened or physically disadvantaged and can also provide some of the same benefits of field trips themselves. More recently, 360° imagery has gained popularity for virtual tours and educators can use specialized camera equipment (e.g., GoPro Fusion) to record the entire panoramic view of an environment. Inexpensive headsets can be coupled with user smartphones to provide a more immersive experience that responds to a student’s gaze as they journey through virtual tours. Here, I explored student perceptions and opinions about viewing virtual tours using immersive reality headsets (e.g., Google cardboard) versus less immersive technologies (e.g., laptops and projectors) in a controlled study of over 300 environmental science students. Virtual tours were popular with the students and helped provide context to learning material; however, when immersive reality headsets were used students reported a significant decrease in their understanding of the course content. The potential causes for this decrease along with recommendations for the appropriate use of both virtual tours and immersive headsets will be discussed in the presentation.

Place-based and fieldwork learning play a key role in higher education in environmental sciences and other geo-spatial disciplines. We report on a study in which we evaluated a web-based virtual tour application for teaching natural resource management in fire-prone western forests in two undergraduate classes. The virtual tour uses 360°-image-based virtual scenes and pre-recorded audio commentary by a domain expert to lead participants through the Stanislaus-Tuolumne Experimental Forest where forest treatments were implemented to reduce fire hazard. We present results from assessing students’ overall perception of the virtual tour, their views towards its application in undergraduate education, and their feedback for improving the design of future virtual tours. Furthermore, we discuss the collected data from the perspective of gender differences and differences in familiarity with the topic of the tour.

Spatial learning is a process of acquiring spatial knowledge and the foundation of our daily interactions with the living environment. Extended reality (XR) has been widely used in spatial learning research for decades with two representative types - Virtual reality (VR) and Augmented reality (AR). VR is often used to understand spatial learning behavior and spatial cognition process, and AR has great potential to assist spatial learning in real world. This short paper reviews the studies on the deployment of VR and AR to evaluate or assist spatial learning. We summarize the devices, technologies and analysis methods used, and identify factors that need to be considered in experimental design. Our work serves as a reference for new researchers who intend to design further user studies on spatial learning with VR and AR technologies.
