This report describes recent efforts to improve the teaching of relevant first-day skills in compounding and prescribing through active learning approaches such as blended learning and online learning resources, including flipped classroom settings and cloud-based documents to practice prescribing at one of the German Schools of Veterinary Medicine. We assessed how the introduction of blended and case-based learning and quizzes impacted learning outcomes and grades over the last 5 years, from 2019 to 2023. This timeframe included regular pre-pandemic teaching operations, remote teaching during the pandemic, and a return to in-person classes. Pandemic online teaching did not lead to worse outcomes in practical or theoretical knowledge; online tutorials for compounding improved student performance significantly during the pandemic, though performance declined after returning to in-person teaching until quiz-based extra points were introduced in 2023. Doubling prescription seminar time did not improve outcomes in 2020, but introducing a cloud-based prescription exercise in 2021 led to better results, and overall grades in pharmaceutical and narcotics law have significantly improved since 2020.
