Researchers have discovered some novel benefits of the technique practice, which is closely related to distributed practice, involving a practice schedule that mixes different kinds of problems or materials within a single study session.

Interleaved practice.

Explanation:

As the exercise explains, the interleaved practice is closely related to distributed practice, involving a practice schedule that mixes different kinds of problems or materials within a single study session. Furthermore, this process of mixing attempts to commit them to memory, to improve their learning skills. It develops a better long term retention and improves the ability to transfer learned knowledge.
