Inverted classes as a successful tool to overcome teaching and learning challenges imposed by COVID-19 lockdown to food microbiology laboratory classes

This study evaluated if the online inverted classes (IC) model maintained high students’ learning engagement and performance on the laboratory component of Food Microbiology during an academic year dominated by COVID-19-lockdown, compared to pre-pandemic years. Porto University students from 2 courses (n = 36-Pharmaceutical Sciences; n = 59-Nutrition Sciences) were engaged. A high rate of students answered they prefer the IC rather than lecture-only style delivery mode and were involved in the IC learning process (prepared classes asynchronously; participated in case-studies resolution during synchronous classes). Very good laboratory final performances were maintained as in pre-pandemic years. Variable perceptions about work volume and adaptation to face-to-face laboratory classes were observed among both groups, potentially related to different course organization and defined learning outcomes/competences.
