Methods and materials

Simultaneously, teledidactic and face-to-face ultrasound courses were conducted, with students completing seven 90-minute modules using handheld ultrasound probe.

Fig 1: The graphic illustrates the process of teaching ultrasound skills online. While students practiced independently, they shared their camera feed with the instructor, enabling real-time guidance and feedback on probe handling when needed. For demonstrations, the instructor shared their iPad screen with the students, helping them identify the anatomical structures to be visualized. Afterward, students uploaded their images to the app's cloud, where the instructor provided comments and ratings on their work.
The course covered a range of topics, including focused assessment with sonography for trauma (FAST), lung ultrasound, and evaluations of the kidney, aorta, thyroid gland, and spleen. Each module consisted of a lecture, a demonstration of probe handling, and self-guided practice sessions. An objective structured assessment of ultrasound skills (OSAUS) was performed as both a pre-test and a final exam, with ultrasound images obtained during the exams evaluated using the brightness mode quality ultrasound imaging examination (B-QUIET) scale.
Fig 2: The timeline of the TELUS-II study outlines the procedures used to evaluate the efficiency of the teaching methods. Both the teledidactic and face-to-face courses were conducted simultaneously, with students completing weekly modules. The final examinations took place over two consecutive days after the eight-week course duration. Abbreviations: FAST (Focused Assessment with Sonography for Trauma), OSAUS (Objective Structured Assessment of Ultrasound Skills), and B-QUIET (Brightness Mode Quality Ultrasound Imaging Examination Technique).
