Two case studies from the University of Strathclyde describe how online assessments and activities replaced some traditional in-person lectures and tutorials. In a French class, online homework, tests, and diagnostic assessments took the place of 50% of tutorials, improving attendance, progression rates, and exam results. In a psychology class, online collaborative group tasks replaced half of lectures, increasing formative feedback and engagement while improving exam scores and failure rates. Both cases highlight how technology can efficiently deliver course content while enhancing learning outcomes.
