Teaching in higher education – there isn’t enough evidence to tell us what works and why

Do I deliver this unit online or face to face? How should I arrange my lesson? Do I incorporate pre-class and post-class activities? What methods should I use to engage my students: problem-based learning, active learning strategies, small group work? Should I ask students to come to class or connect remotely? If they come to class, should I ask students to bring and use their own devices? How should I arrange the classroom furniture for my lesson? Does it matter what I do or how I do it?
