Should law students use flashcards?
Yes, for the right material. Law exams reward applying rules to new facts, so flashcards cannot be your whole strategy, but you cannot apply a rule you cannot state. Flashcards are well suited to black-letter rules, the elements of a claim or defense, and standards of review. Use them to make recall automatic, then spend your practice time on hypotheticals and past exams where you apply those rules.
Practice testing is one of the two study techniques rated “high utility” in a major review of learning research (Dunlosky et al., 2013). Self-testing on rules through the semester also means less cramming during the reading period before finals.
