I’d like to share ten benefits proposed by psychology experts Henry L. Roediger III, Adam L. Putnam and Megan A. Smith in a recent paper, “Ten Benefits of Testing and Their Applications to Educational Practice”.
Here is my summary and understanding:
- Retrieval aids later retention. There is clear evidence from psychological experiments that practicing retrieval of something after learning it, for instance by taking a quiz or test, makes you more likely to retain it for the long term.
- Testing identifies gaps in knowledge.
- Testing causes students to learn more from the next study episode. Essentially it reduces forgetting which makes the next related study area more productive.
- Testing produces better organization of knowledge by helping the brain organize material in clusters to allow better retrieval.
- Testing improves transfer of knowledge to new contexts. There are several experiments referenced in the paper where tests and quizzes help transfer and application of knowledge.
- Testing can facilitate retrieval of material that was not tested. Surprisingly there are circumstances where quizzes or tests, particularly if delayed, can help people retrieve/retain information that was related to that asked but not actually asked in the questions.
- Testing improves metacognitive monitoring – by giving students scores or self-assessments, they can better predict their knowledge and be more confident about what they know and what they need to know.
- Testing prevents interference from prior material when learning new material. If you have a test after learning one set of material before learning another set of material, it can make it less likely that the second session will.
- Testing provides feedback to instructors and lets them know what is learned or what is not.
- Frequent testing encourages students to study. Having frequent quizzes and tests motivates study and reduces procrastination.
