Which study strategy promotes deeper understanding and transfer by mixing topics in one session?

• A. Interleaving
• B. Spacing
• C. Encoding
• D. Retrieval

Answer: (A)

Mixing different topics or problem types within one study session challenges you to switch gears, retrieve the right strategies, and decide which approach fits each situation. This repeated retrieval and comparison across topics strengthens connections and helps you apply what you’ve learned to new contexts, not just memorize patterns. For example, alternating algebra, geometry, and word problems in the same session trains you to recognize cues and choose the appropriate method on the fly.

Spacing distributes practice over time, which boosts long-term retention but doesn’t inherently mix topics in a single session. Encoding is about how you initially process information, and retrieval practice strengthens memory—both valuable but not defined by mixing topics in one sitting. Interleaving uniquely promotes deeper understanding and transfer by mixing topics in one session.
