Effectiveness of a digital interactive multimedia tutorial for preparing veterinary students to perform ultrasonography in horses

Development and Implementation of a Basic Veterinary Ultrasound Curriculum

Diagnostic ultrasound is an important imaging modality in veterinary medicine. Surveys of veterinarians suggest that ultrasound is a desired clinical competence and that new graduates are expected to practice basic ultrasound skills. This report describes the development and implementation of a basic ultrasound training program in the core curriculum at Iowa State University College of Veterinary Medicine (ISU-CVM). A multidisciplinary team of ISU-CVM faculty created and delivered a basic ultrasound training program consisting of two lectures and two hands-on laboratories incorporated into a second-year core course, utilizing ballistic gel and silicone phantoms as well as live-dog scanning. The focus of training was on basic image acquisition, image optimization, and regional sonographic anatomy of the canine abdomen. Students were surveyed at 6-month intervals during program implementation. Survey data from graduating students, alumni, and employers were also analyzed. The program was successfully implemented and was well-received by all key stakeholders. Alumni and employer surveys reinforced the importance of basic ultrasound skills as a competency for new graduates. Student survey data revealed that satisfaction with ultrasound training increased after implementation of the program, as did students' perception of their skill level in individual ultrasound competencies. Student surveys also identified ways to enrich the program by providing additional opportunities for ultrasound practice in subsequent laboratory courses and clinical rotations. This report summarizes lessons learned during development of basic ultrasound training in the core curriculum at ISU-CVM and can serve as a reference for other institutions considering similar programs.

Impact of the educational setting on the teaching and learning of the equine distal limb ultrasonography

The use of immersive methodologies is a trend in the educational environment, but their outcomes in the teaching-learning process need to be better understood. This study aimed to assess the impact of the educational environment on learning equine distal limb ultrasonography, comparing immersive classroom, traditional classroom, and virtual classroom. A total of 153 veterinary medicine students from the first to the third semester participated in this study. The students were divided into four groups: traditional (n = 22), immersive (n = 100), online (n = 31), and traditional-immersive (n = 15). The students completed a questionnaire before and immediately after the class. The online group had a lower average gain in correct answers compared to the others (p < 0.01). Regarding student perception, it was observed that the virtual group had the lowest satisfaction score (p < 0.001), and students in the immersive and online environments were more satisfied with the resources used compared to the traditional classroom (p = 0.01). Concluding, in the present study students showed a greater interest in environments associated with technology, and that in-person modalities resulted in significantly superior learning outcomes compared to online ones.

Development of an Online Distance Learning Platform Combining Anatomy, Imaging, and Surgical Practice to Support Mastery Learning of the Equine Locomotor Apparatus

There are many challenges in teaching veterinary anatomy, such as available classroom time, costs, and difficulties accessing animal cadavers, mainly due to animal welfare concerns. Furthermore, veterinary surgeons and radiologists complain that recent graduates lack anatomical knowledge. On the other hand, the current limitations of face-to-face teaching due to the COVID-19 pandemic suggest that the development of online distance education tools is necessary, mainly in specialties that lack this type of material. Teaching platforms promoting the integration of anatomy with other applied disciplines such as imaging and surgery in the horse were not found in the consulted literature. Therefore, this work aimed to develop an online distance education platform for studying the surgical anatomy of a horse's locomotor apparatus as a complementary tool for training students enrolled in undergraduate courses in veterinary surgery. The locomotor apparatus was chosen as the focus as it is the most commonly found in equine surgeries. Anatomical pieces referring to the locomotor apparatus were prepared. These were complemented with material related to diagnostic imaging, surgery videos, theoretical explanations, and an interactive radiological anatomy tool. Finally, all the material was uploaded to a virtual platform accessible via the Internet. The platform is expected to be a tool that helps students in surgical training and prepares them with a better understanding of anatomy and its application in surgery.
