The COVID-19 pandemic has accelerated the digital shift in higher education and forced university faculty to transform their courses into a blended or online modality to comply with current public health measures. Many instructors have implemented blended online courses, which combine synchronous and asynchronous online teaching and learning activities. The purpose of this study is to document university students' learning experiences in blended online courses during the pandemic, and to identify instructional strategies to support student engagement in these courses. It adopts a mixed-methods research strategy in which data were collected through questionnaires from students who took a blended online course in the summer semester of 2020, in a variety of disciplines and academic cycles at four Quebec universities (n = 482). Following the analysis of student responses to open-ended questions, five recurring themes were identified: the enhancement of student-student interactions, the dynamism of synchronous and asynchronous sessions, the structured presentation of the course, the explanations and feedback from instructors, and the accessibility and involvement of instructors. For each theme, suggestions from student feedback are provided to facilitate student engagement in blended online courses.
