Answer: The correct answer is: Geoff, who has been studying an hour a night over the last three weeks for his anatomy final.
Explanation: Distributed practice is understood as a learning method or strategy that consists of breaking up the operation into short sessions over a longer period.
An example of the distributed practice is a student who distributes his/her study over several short sessions over multiple weeks instead of cramming it up into one long session.
The distributed practice has shown to have benefits in the acquisition of new learnings, long term learning and a bettering in the general academic performance of students.
In conclusion, Geoff is the only student who is engaging in distributed practice because he has been studying an hour a night over the last three weeks for his anatomy final.
