No, this does not mean just oversimplifying the information at hand. Students are far more likely to retain information taught by sticking with key concepts and important ideas rather than just trying and "control-V" the information word for word from their brains to the page.
Students who are attempting to summarize information may be allowed to close their laptops/other devices showing them the information and vocalize a summary or do a quick summarization on paper.
Sketchnotes are visual representations of challenging concepts students can use to help them imagine what they're learning. They are also a great graphic organizer for the artist/creative type students in the class.
Along with sketchnotes, other visual aids like flow-charts and concept maps can also help the class conceptualize the important information.
Asking students questions is a time-honored practice, something that never fails to get some kind of response from the class. Whether that response is positive or negative, however, is always left up to chance. Asking good questions can get a class thinking. Yes or no questions can activate surface level thinking and participation, but other types of questions can do the job much better.

Asking "great" questions allows a class to engage with the content on more than one level. Explaining, exploring, and interpolating can do miles more than just asking them whether something is true or not.
