Final answer:
The correct answer is option B, which describes a study session where a student alternates between history, math, and Spanish, exemplifying the interleaving technique.
Step-by-step explanation:
The concept of interleaving refers to the practice of alternating between different subjects or types of material when studying, rather than focusing intensely on a single subject at a time. This approach has been shown to improve retention and understanding. Looking at the options provided:
- (A) represents spaced repetition rather than interleaving.
- (B) is an example of interleaving, as it involves studying different subjects sequentially within the same study session.
- (C) represents blocked practice, which is the opposite of interleaving.
Therefore, the correct answer is (B) studying history for 1 hour followed by 1 hour of studying math followed by an hour of studying Spanish.
