Actually, strong evidence that reports higher exam scores and lower failure rates with active learning comes from large lecture courses, often with hundreds of students in the room. Active learning is not just for small groups, but can easily be implemented even in very large classes.
The question is rather how to structure interaction so that it scales in a large group. There are many small activities that can be used in lectures and tutorials without you having to individually respond to each student, or to give feedback to hundreds of separate hand-ins. Check the examples in these best practice stories by your peers in maths or in cell biology. Or watch this video on using worksheets in a large algebra lecture to engage students.
