Site visits or field trips are widely recognized by construction educators to engage students in active learning, supplement traditional lessons, and achieve better student learning experiences. However, site visits pose significant logistical and accessibility challenges for educational institutions and teachers, limiting the number of students who can benefit from them. Moreover, the restrictions on site visits have widened recently, as the reality of COVID-19 public health concerns have compelled instructors to fast-transition to online course delivery, canceling most site visits. The purpose of this study is to present construction students with online site visits to supplement contextualized learning in risky, unsafe, or impossible-to-achieve situations. In this project, Mozilla Hubs® was used to establish a virtual collaborative environment that resembled a real-world site visit to a building facility. A pilot study (i.e., a plan-reading assessment) was employed within the virtual environment that provided affordances involving an in-depth learning experience through collaborative communication. The findings demonstrate that virtual collaborative site visits give unique chances to deliver spatiotemporal contexts of sites online and provide an effective remote alternative when these learning opportunities are unavailable.
iVisit: Digital Interactive Construction Site Visits Using 360-Degree Panoramas and Virtual Humans
Site visits or field trips are an integral part of construction management education, providing students with experiential learning of jobsite conditions. However, these types of real-world opportunities are difficult to obtain within the current educational framework based on classroom instruction. To expose students to jobsite spatiotemporal contexts (spatial, temporal, or social situations), field trips must be organized at locations that are often inaccessible, dangerous, or expensive to reach. To address field trip barriers, this research proposes the use of iVisit—a proof-of-concept platform for guided interactive site visits that leverages 360-degree panoramas and virtual humans. In this paper, the technical requirements for the creation of digital site visit experiences and resulting educational platform are explained in detail. Additionally, a pilot study was conducted to assess the iVisit platform in terms of usability, presence, and student knowledge gains. A masonry materials’ site visit learning experience was designed and tested with 10 participants at introductory level construction courses. It was found that students perceived the iVisit guided tour as easy to use (SUS Usability Score – Mean = 86%; STD = 8.8%) and highly realistic (SUS Presence Score – Mean = 68.4%; STD = 14.4%). However, students answer approximately one-third of the presented knowledge questions correctly (Student Knowledge Score – Mean = 31.7%; STD = 25%). These outcomes in student knowledge gains were linked to low image quality in the 360-degree captures and augmented pictures within the digital site. Supporting feedback provided by the study participants suggested that future improvements to iVisit require higher image quality and some refinements to its user-interfaces to increase presence and knowledge gains.

Effective communication is essential for students in construction management and relevant fields. Nevertheless, very little emphasis on communication practices has been placed in the construction management curriculum, and limited communication skills are still widely found among students. Ideal construction site visits not only supplement traditional learning in the classrooms but also provide opportunities to communicate with professionals onsite. However, challenges exist that limit the application of site visits and ultimately reduce such opportunities to practice communication skills with experts on the jobsites. This research aims to help overcome the barriers by proposing a novel approach that leverages 360-degree digital sites with virtual human as conversational partners on site (iVisit-Communicate). In this paper, the design and development processes of iVisit-Communicate were described in detail, followed by a case study of its implementation on a digital site visit to a mechanical room. It was found that most students agreed that iVisit-Communicate provided them an opportunity to practice communication skills.more » « less

null (Ed.)The construction field trip is an interactive and essential component of construction education, and its significance is widely recognized by educators and researchers in the construction domain. However, due to its real-world nature, there are several challenges that limit the extensive employment of this teaching approach. A few examples of such spatiotemporal challenges are time conflict, large class sizes, short site visit duration, and not being able to see or hear in a crowded or noisy environment. Construction educators and researchers have been using virtual field trips to support traditional field trips or offer an alternative when these learning opportunities are not available. This paper presents the current status of virtual field trip application in construction education while specifically focusing on the construction subject areas, technology use, and learning assessment techniques used in those virtual field trips. The review shows that VFT has been mostly integrated with construction courses in fundamental and introductory level, and their learning objectives are mainly general and broad without a specific focus on certain construction aspects or techniques. The technologies to develop VFTs can be categorized into captured-reality using regular or 360 images or videos and virtual reality using computer-generated simulation of reality. Advantages and disadvantages of both technologies are discussed. Interview and questionnaires were mainly used to assess the reviewed VFT as a learning tool, and it is reported that in the majority of those papers, the feedback from students is mostly positive. These outcomes provide construction educators and researchers insights on successful implementation and potential challenges of virtual field trips in construction education.more » « less

Field learning is fundamental in geoscience, but cost, accessibility, and other constraints limit equal access to these experiences. As technological advances afford ever more immersive and student-centered virtual field experiences, they are likely to have a growing role across geoscience education. They also serve as an important tool for providing high-quality online instruction, whether to fully online degree students, students in hybrid in-person/remote programs, or students experiencing disruptions to in-person learning, such as during the COVID-19 pandemic. This mixed-methods study compared learning outcomes of an in-person (ipFT) and a virtual (iVFT) geoscience field trip to Grand Canyon National Park, each of which highlighted the Great Unconformity. Participants included introductory and advanced geology students. In the ipFT, students collectively explored the Canyon through the interpretive Trail of Time along the Canyon rim, guided by the course instructor. In the iVFT, students individually explored the Canyon and studied its geology at river level. 360° spherical images anchor the iVFTs and serve as a framework for programmed overlays that enable active learning and allow for adaptive feedback. We assessed cognitive and affective outcomes in both trips using common measures. Regression analysis showed the iVFT to be associated with significantly greater learning gains. The ipFT students had significantly higher positive affect scores pre-trip, reflecting their excitement for the trip. Overall, our results provide clear evidence that high-quality iVFTs can lead to better learning gains than ipFTs. Although field trips are employed for more than just content learning, this finding may encourage greater use of iVFTs in coursework.more » « less

The reality of COVID-19 public health concerns and increasing demand for distance education have forced educators to move to online delivery of their courses. Particularly in construction education, the majority of physical location-based educational activities (e.g., labs, site visits, or field trips) have been canceled during the pandemic that results in reducing students’ engagement, learning motivation, and cognitive achievement. Virtual Social Spaces (VSS) with innovative interaction affordances and immersive experience are well poised to supplement current online construction education. This paper discusses the potentials of VSS for construction education while focusing on the common applications of VSS, the communication and collaboration affordances of VSS, and design principles of this technology based on 15 popular VSS platforms. Overall, VSS applications are mainly found in education, entertainment, and socializing. The main communication and collaboration affordances of VSS include avatars, multi-user support, asynchronous commenting, synchronous chat, and visual-sharing affordances. These technical features illustrate the potentials of VSS for improving online construction education quality, eliminating the challenges associated with geographical dispersion of students, and decreasing the students’ lack of engagement.
