11 pages, Virtual fencing (VF) is a modern fencing technology that requires the animal to wear a device (e.g., a collar) that emits acoustic signals to replace the visual cue of traditional physical fences (PF) and, if necessary, mild electric signals. The use of devices that provide electric signals leads to concerns regarding the welfare of virtually fenced animals. The objective of this review is to give an overview of the current state of VF research into the welfare and learning behavior of cattle. Therefore, a systematic literature search was conducted using two online databases and reference lists of relevant articles. Studies included were peer-reviewed and written in English, used beef or dairy cattle, and tested neck-mounted VF devices. Further inclusion criteria were a combination of audio and electrical signals and a setup as a pasture trial, which implied that animals grazed in groups on grassland for 4 h minimum while at least one fence side was virtually fenced. The eligible studies (n = 13) were assigned to one or two of the following categories: animal welfare (n studies = 8) or learning behavior (n studies = 9). As data availability for conducting a meta-analysis was not sufficient, a comparison of the means of welfare indicators (daily weight gain, daily lying time, steps per hour, daily number of lying bouts, and fecal cortisol metabolites [FCM]) for virtually and physically fenced animals was done instead. In an additional qualitative approach, the results from the welfare-related studies were assembled and discussed. For the learning behavior, the number of acoustic and electric signals and their ratio were used in a linear regression model with duration in days as a numeric predictor to assess the learning trends over time. There were no significant differences between VF and PF for most welfare indicators (except FCM with lower values for VF; P = 0.0165). The duration in days did not have a significant effect on the number of acoustic and electric signals. However, a significant effect of trial duration on the ratio of electric-to-acoustic signals (P = 0.0014) could be detected, resulting in a decreasing trend of the ratio over time, which suggests successful learning. Overall, we conclude that the VF research done so far is promising but is not yet sufficient to ensure that the technology could not have impacts on the welfare of certain cattle types. More research is necessary to investigate especially possible long-term effects of VF.
9 pages, As the food industry becomes globally connected, it is essential to provide Food Science students with experience working in virtual teams before they enter the workforce. Working in teams virtually brings extra challenge due to a lack of face-to-face interactions. FSHN 230, Professional Issues in Food Science (asynchronously online), provided students the opportunity to practice virtual teamwork skills. Low, medium, and high dosage team projects allowed for experiential learning and practice in virtual teamwork. Team effectiveness (psychological safety, dependability, structure and clarity, meaning, and impact) was closely monitored using team members’ evaluations of the team at the middle and end of the semester. Students' perceptions of learning were assessed using a survey at the end of the instructional period. Across all teams, students were most likely to report experiencing psychological safety and dependability in their virtual teams and least likely to report experiencing the work as meaningful. Across all teams, students were most likely to perceive the virtual team project as assisting with learning about food science-related careers. As higher education continues to create real-world simulations to teach skills, such as virtual teamwork, more effort may be needed to help students connect classroom activities and career-ready skills to real-world expectations.
9 pages, via online journal, This article provides an overview of Extension's Military Families Learning Network. The network is an example of Extension's commitment to building virtual learning networks in the support of targeted professional and lay audiences. The network uses well-established and emergent pedagogical approaches focusing on adult-centered learning while employing state-of-the-art online learning technologies. We present a four-dimensional model of learning activities to illustrate how the network offers different options for and approaches to adult-centered learning and training. The Military Families Learning Network can serve as a model for broader adoption of such entities across the Extension community.
3 pages., Via online journal., Student engagement in the classroom is critical for effective learning. To enhance student engagement, several teaching approaches can be used, including a flipped classroom approach and virtual field trips. The flipped classroom approach was used in an undergraduate tropical production systems course in which students viewed lecture materials outside of class, brought their smart devices to class to review materials, searched for new information on the Internet, and participated in small group discussions. In the virtual field trip assignment, each student visited a commercial farm or nursery, interviewed the owner or manager, and gave a presentation to the class about the operation of the enterprise and its sustainable practices.
7 pages., Via online journal., Virtual plant walk maps were developed for an ornamental plant identification (ID) course, with the goal of providing an additional study resource to potentially enhance student learning. The maps provided students an opportunity to revisit plants covered in lecture and laboratory sections at their own convenience, using either a computer or mobile device. Each map plotted the locations of the plants from the corresponding list and provided photographs of specimens, plant family, common and scientific names, and plant type information. At the end of the course, a survey was given to collect information about student use and perceptions of the virtual plant walk maps for two fall semesters (n = 87). Survey results indicated 63% of the students used the virtual plant walk maps as a study resource. Students who used the maps reported accessing the maps an average of 3.2 times between receiving the maps and taking the plant ID quiz in laboratory. Students mainly used the maps to study the most current plant list and accessed previous plant list maps to a lesser extent. About 67% of students who used the virtual maps, used the maps to visually review the plants online only, although 31% of students used the maps for both visual review and to physically retrace the plant walk to view the live specimens. Of the students who did not use the maps, most found other study resources/methods more useful or they forgot about the maps as a resource. When asked to rate usefulness of the maps on a scale from slightly useful (1) to very useful (3), 43% of students indicated that the virtual maps study tool was very useful, 25% indicated the maps were useful, and 8% indicated that the maps were slightly useful. A significant dependence between student use frequency and student usefulness ratings of virtual plant walk maps was observed. As students’ use of the virtual maps increased, they perceived the maps to be more useful to their studies in preparing for ID quizzes. No differences between plant ID quiz scores were associated with virtual plant walk map use, learning style, or use by learning style. Our survey indicated that students used the virtual plant walk maps as a resource and perceived the maps as a useful tool in preparation for ID quizzes.
