Research on how to support learning with scenarios that are relevant to the specific situation. Even though this is explicitly about workplace training, the major recommendations could be adapted for instructional design in education contexts too.
Utilize decision-making scenarios. Consider using them not just in a minor role—for example at the end of a section—but integrated into the main narrative of your learning design.
Determine the most important points you want to get across AND the most important situations in which these points are critical. Then, provide extra repetitions spaced over time on these key points and situations.
