Students who added a lesson with breaks to physics made greater gains
In physics as a separate subject at six English schools, adding it before the usual class was associated with gains 50% to 90% greater.
The key idea
In separate-subject physics, adding a lesson with breaks to usual instruction was associated with greater gains, which varied by course.
The study, in plain language
The lesson lasted an hour and alternated three physics blocks of 11 to 14 minutes with two 10-minute breaks. At six English schools, researchers compared using it alone, using it before usual instruction, or continuing with usual instruction only.
In physics as a separate subject, combining the spaced lesson with later instruction was associated with greater gains on the delayed test. Combined-science courses, which bring several subjects together, also had greater gains than the control, although that group started with lower scores. Results depended on the course and highlighted the full teaching sequence.
What they found
- In separate-subject physics, combining the lesson with breaks and usual instruction was associated with greater later gains.
- Combined science also showed greater gains, with a lower starting level in that group.
- Results varied by course and favored the combination with later instruction.
Something to think about
A lesson is not only what is explained; the pauses matter too. What do you do during breaks when you study something long?
How they studied it
At six English schools, researchers compared usual instruction with a one-hour lesson divided into three blocks and two breaks, offered alone or before the usual class. There were 548 students; 336 completed all assessments, including a delayed test two months after the final instruction.
What the study cannot show
- The study included six English schools and one physics topic. Many students did not complete all assessments; results varied by course and starting level. Schools delivered the intervention with remote supervision.
- The study does not show that a one-hour session can replace a full course or works the same way in other subjects or groups; the strongest result was for combining the spaced format with later usual instruction.
