Among the most effective educational interventions are those with testing components. Testing can be used effectively to promote learning, but that means using it more often in spaced, shorter bursts. Optimally, teachers should test their students on material at the moment they begin to forget it--the more discrete the subject matter (e.g., mathematics) the shorter the time interval between tests.

12. Why tests?
●
Students tend to study more, and learn more, when:
• they know they will be tested, but not precisely what will be tested
» (e.g.) Experiment comparing gains of students with “take-home tests” to
those with “in class tests” -- the latter learned substantially more.
• when there is reinforcement of material already studied
●
Mastery learning experiments of 1960s—1980s:
» Students learn more when asked to recall what they have learned.
» Up to a point, the more students are made to actively process information,
and describe it to others, the better they learn.

15. “Repeated retrieval during learning is the key to long-term retention.”

16. 10 benefits of testing and their applications to education
Roediger, Putnam and Smith
Direct effects of testing
Retrieval practice during tests enhances retention of the retrieved information
(relative to not testing or even to studying) -- the “testing effect”
Repeated retrieval produces knowledge that can be retrieved flexibly and
transferred to other situations
On open-ended assessments (e.g., essay tests) retrieval practice induced by
tests helps students organize information into a coherent knowledge base.
Repeated retrieval leads to easier retrieval of related information

Learning and Motivation, 55, 2011.

17. 10 benefits of testing and their applications to education
Roediger, Putnam and Smith
Indirect effects of testing
Students tested frequently study more and with more regularity.
Tests permit students to discover gaps in their knowledge and adjust their
study efforts to focus on difficult material.
Students who study after taking a test learn more than if they had not taken a
test.
Students who self-test or are tested more frequently in class learn more.

Learning and Motivation, 55, 2011.

20. 10 benefits of testing and their applications to education
Roediger, Putnam and Smith
Most teachers should be testing much more
frequently, …with smaller, shorter, less
consequential tests.
Students learn more when they test. But
learn best when the tests are “spaced”.
What is the optimal lapse of time between tests?
The best time to test again is just before students start forgetting the
information. This time lapse is shorter with discrete material, like
mathematics, than with other subjects. Some studies suggest that math
students should be tested at least once a week.

21. The more high-stakes decision points, the better the
student performance ?

23. What testing skills do teachers need…
…for interpreting information from large-scale tests?
Basic understanding of statistics:
- distributions, mean, median, skewness, kurtosis
- sampling error, measurement error
- type 1 / type 2 error, statistical power
- sampling (size, representativeness)
Protocols to help them explain
tests to others:
- to students
- to parents
- to the media

24. What testing skills do teachers need…
…for developing and administering classroom tests?
Practice (with each other) in writing
items / prompts / rubrics :
- unambiguous, relevant, un-biased
Understand that useful assessment can
be very simple:
- e.g., save the last few minutes of
each class to assess by asking
students to record 2-3 concepts they
learned that day
Learn the optimal frequency, spacing of tests for your subject field and grade level.

25. It is easy to know what you are teaching.
But, you can only know what students are learning if you assess.
