To adequately prepare students for engineering practices, it is imperative that institutions adopt innovative methods of teaching, learning, and assessment. One such approach is the use of real field trips (RFT) to construction sites, which can enhance students’ perceptions of related careers. Although virtual field trips (VFTs) have emerged as a viable alternative—or supplement—to traditional field trips, little is known about their potential to provide the same or similar career exploration advantages. Using responses from a self-reported questionnaire administered to university students who participated in an RFT, this study sought to examine the usefulness of site visits in developing essential skills required for civil engineers. It also examines student perceptions on the use of VFTs as part of their university experience and the extent to which it could replace RFTs. The results indicate that students consider VFT as an enjoyable way to learn, given the possibilities facilitated by the new technology. However, notwithstanding its success, the students commonly opined that VFT was not a substitute for a RFT. From a holistic perspective, the issue is not whether VFTs can replace traditional field trips or not; it is rather the focus on identifying an integrated approach that combines lectures, and virtual and real field trips in a manner that supports a social constructivism mode of learning. Ultimately, this combination will enable students to effectively construct multiple links between lectures given in a hall and the real world outside.

Fieldwork has long been considered an essential component of geoscience research and education, with student field experiences consistently valued for their effectiveness in developing expertise in geoscience skills and cognitive abilities. However, some geoscience disciplines recently have exhibited a decreasing focus on data collection in the field. Additionally, some students have been disinclined to pursue a geoscience career if physical fieldwork is perceived as necessary for the completion of their academic degree. More recently, travel restrictions due to the COVID-19 pandemic have restricted access to field locations for many students and geoscience researchers. As a result, geoscience educators are developing virtual field trips and exercises that address many of the learning objectives of traditional in-person field experiences. These virtual field trips and exercises use a variety of online and computer platforms, including web-based and desktop versions of Google Earth (GE). In this contribution, we highlight how educators can create virtual geoscience field trips and exercises using web GE, desktop GE, and a web-based tool for generating oriented geologic symbology for GE. Examples of methods and approaches for creating virtual field experiences in GE are provided for a virtual field trip that uses a web GE presentation to replicate a typical class field trip, and for a geologic mapping exercise that uses a KML file uploaded into web or desktop GE. Important differences between web and desktop GE are discussed, with consideration for which platform might be most effective for specific educational objectives. Challenges and opportunities related to virtual field trips are discussed in comparison with traditional in-person, on-location field trips. It is suggested that in a post–COVID-19 world, a combination of in-person and virtual hybrid field experiences might prove the most effective approach for producing a more inclusive and equitable learning environment, and thus strengthening the geoscience workforce.

The efficiency of virtual field trips (VFTs) compared to their physical counterparts, is often regarded as one of their key benefits. Virtual field trips are typically more time, cost and environmentally efficient and logistically easier to plan and execute. This is largely due to the lack of travel, however, the nature of these efficiencies, which is essential for deciding whether a trip should be virtual, physical or blended, have not previously been quantified. Here we present a quantitative evaluation of several measures of efficiency, using data from a like-for-like comparison between 10 day long virtual and physical field trips to Utah, USA, from the University of Aberdeen, UK. For this case study, our results demonstrate that virtual field trips are more efficient across all the categories of time, cost, environmental impact, and logistics. In addition to saved air travel days at the start and end of the physical trip, a further 33.3% of the time on the physical field trip was spent travelling (walking and driving). This time saving allowed an additional 16 localities to be visited on the virtual field trip. The virtual field trip localities also ran in an order that best suited the geological narrative rather than their geographic location which the physical field trip was restricted by. Flights and driven kilometres for the physical trip produced c. 4 t of carbon dioxide equivalent (CO2) per student. The virtual trip produce <1% of the CO2 and was comparable to a typical teaching week, making it significantly more environmentally efficient. The cost of the virtual trip was negligible compared to that of the physical trip (saving up to £ 3000 GBP per student). These findings were compared to the fulfilment of learning outcomes, quantified primarily through questionnaires, the student responses suggest that the PFT and VFT perceptions of learning outcomes were generally comparable. Efficiency is not the only measure of a successful field trip, with other parameters such as social cohesion and embodiment within the outdoor environment that must also be considered when planning a field trip. Therefore, the authors do not advocate or support an abandonment of physical field trips. Rather, this study aims to provide a first attempt to quantify efficiency to inform decision making when planning field training.

Service-learning (SL) is a high-impact pedagogical strategy that has been shown to have both cognitive and affective benefits for students and has the potential to engage and involve a more demographically diverse spectrum of students into the field of STEM. However, research on the impacts of SL in STEM courses is limited, and therefore there is a great need to identify the specific outcomes linked to participation. In addition, faculty from STEM fields have been hesitant to incorporate SL into their curriculum due to perceptions that it lacks academic rigor. This purpose of this mixed-methods case study was to examine how participation in SL in an introductory environmental science course specifically impacted students’ knowledge of course content and development of agency, both at the projects and beyond. Students in the study participated in a range of different SL projects through the course. SL outcomes were compared across different types of SL projects to determine the overall impact of SL on course content and agency growth, as well as to more effectively assess the general characteristics of projects that fostered growth in these areas. The findings from this study showed that SL participation led to increases in both course content knowledge and agency. Students with high course content knowledge growth also had exhibited high agency in the projects. The findings did not, however, show any significant differences in course content growth and agency across projects. This is likely due to the fact that all the SL projects in the study were well established and already using best practices in their projects. The results of this study contribute additional research on SL impacts in STEM to the field and also help guide best practices for the future.

Geoscience courses, such as geology and geomorphology, require not only classroom lessons and laboratory exercises, but field trips as well. However, the COVID-19 restrictions did not allow the prosecution of most planned field trips, and an alternative needed to be developed. The use of virtual field trips is one such alternative. Through them, one can not only visit any area of interest, but prepare themselves for any actual educational or exploratory field trip as well. Even though they do not, and should not, substitute any physical visit of a site of interest, they have many advantages when combined with a "live" field work, in comparison to a field trip for which no preparation has been made. Through this research, we compare the advantages and disadvantages of both virtual and real educational field trips based on the opinions of our students. We thus performed a virtual navigation on the island of Naxos, Cyclades (Aegean Sea, Greece) for a series of virtual field trips, which took place during webinars in the framework of Erasmus+ CIVIS. The virtual fieldtrip was also presented to the third-year students of the Faculty of Geology & Geo-environment, National and Kapodistrian University of Athens, in the framework of the obligatory course of Geomorphology. Upon completion, all participating students were asked to fill in a questionnaire in order to evaluate the contribution of virtual field trips to their education regarding geomorphology and state their opinion as to whether they can supplement and/or substitute actual field trips. Most of them stated that virtual field trips can aid, but not substitute the actual field work. Most students mentioned that they would attend another virtual field trip in the future, both as an alternative to classroom lessons and as a means of preparation for an actual field trip, but not in order not to attend the actual one.

Virtual field trips open new possibilities for instructional designers to create more interactive worlds for learners. Three virtual field trips are examined which have all been developed for the Open University undergraduate science courses and make clever and innovative use of QuickTime Virtual Reality to allow students to enter three contrasting environments. Learning gains have been ascertained from pre- and post-test cognitive change scores. Perceived learning was also measured with a post experience questionnaire. The findings are interesting in that students felt they learnt more from the virtual environment than standing in the cold identifying biological samples. However, when it came to dealing with rock samples, students wanted to handle the real thing. This paper describes the advantages and disadvantages of using virtual science field trips and suggests the fine-tuning of feedback to students requires careful consideration in these types of virtual learning environments.

The importance of education to address current sustainability challenges in small island states has been widely recognized. Environmental education may increase knowledge, while also increasing environmental awareness and motivating students to become agents of change. Student engagement in introductory environmental science courses may benefit from operationalizing abstract concepts by embedding course material and activities within this local context. Here, we describe an introductory course in environmental science that has been tailored to the local context of a small island state in the Caribbean. In addition to reaching academic course goals, pre- and post-course surveys showed that course participants’ environmental awareness increased on the dimensions ‘Personal Value System’ and ‘Willingness to Take Environmental Action’. The described course provides a template for the development of a low-cost introductory environmental science course that integrates general theory and application within the context of Caribbean island states.

Virtual Field Trips (VFTs) have emerged as an alternative to Traditional Field Trips (TFTs), addressing logistical, financial, and accessibility constraints in geoscience education. This study presents a comparative analysis of the educational impact of a VFT and a TFT implemented with the same 10th-grade class in a Portuguese secondary school. The VFT, focused on volcanism and its socioeconomic impacts, used Google Earth to explore the island of São Miguel in the Azores. The TFT, centred on the rock cycle, was conducted at the Lavadores Beach geological site. Both interventions followed the field-based learning model by Orion and were structured around three phases: preparation, field trip (virtual or traditional), and post-activity synthesis. Data was collected through diagnostic tests, schematization, observation grids, student reports (snapshot), group projects, and written responses to a fieldwork guide recorded on Padlet during the VFT and TFT. The results showed that both VFTs and TFTs enhance conceptual understanding and student engagement, though they foster different skills: VFTs strengthen digital literacy, improve accessibility and inclusion for students with mobility or geographic constraints, allow for content revisitation, foster collaboration among students, integrate multimedia resources, and enable virtual exploration of remote locations that would otherwise be inaccessible. They also offer reduced costs, greater scheduling flexibility, and allow for individualised pacing of student learning. In contrast, TFTs provide richer sensory and practical experiences that are essential for hands-on scientific inquiry and foster stronger connections with the natural environment. The study concludes that a complementary use of both strategies offers the most inclusive and effective approach to teaching geosciences.

An interactive environmental modular science course (EMS) has been designed for education science majors preparing to become teachers at the primary and secondary level. The purpose of the EMS course is to give students experience in (i) the inquiry method to learn science, (ii) the hands-on approach in gathering data, (iii) the evaluation of data to understand scientific theory, and (iv) the application of inquiry, hands-on methods in the classroom. This course utilizes a three-phase approach: fieldwork and field trips; data evaluation and laboratory experience; and Internet course and interactive Web conferencing. The EMS course is described and examples of data collected by students are provided.
