From the result of the research Professor Butler provides six recommendations for best practice interactive exercises. Avoid complexity, as digital learning technology gives more opportunities for complex interactive items has become more common when creating interactive questions for tests and learning. However, as interactive exercises make the exercise more complicated for the learner. It does not help understanding and higher-order thinking at the same level. The complex interactive exercises tend to be too much about the form at the expense of content and deeper learning. Another recommendation is to focus on the engagement of specific cognitive processes and make it challenging for the learner, but not too difficult. And again, something that has been much easier to create in the digital age, namely focus on qualitative feedback, that is inevitable for qualitative learning with interactive exercises but also works as a formative added value in tests.
