Many lecturers hesitate because they think active learning means tearing up their whole course and starting from scratch. In reality, you can begin with tiny changes that leave your overall design intact and still make a difference. Gradually, you can build in more active learning components when you get good results.
In fact, most lecturers in studies on the topic do that; they make small changes to their lectures to promote interactivity, or replace a few elements of a course, rather than everything at once. More elaborate active learning strategies can for example be used to revive underattended or passive tutorials; check the examples and templates in the STEM active learning activity finder or read some of your peers best practice experiences.
Time constraints are a frequently cited barrier, but the literature indicates that modest planning yields large returns. Tackle the design of appropriate activities as a planning strategy that balances difficulty, duration, and course constraints. Actions that require little extra class time and that can be increased and/or reiterated over the years.
If your schedule is fully packed, it might actually be wise to reconsider the ILOs and end-terms. Sometimes content gradually increases year by year, without losing what is no longer appropriate. Or, reconsider the number of lectures and the content covered in each lecture, to prevent information and brain overload (also see Why active learning works in STEM).
