Interteaching: the impact of lectures on student performance.
A quick lecture at the start of interteaching lifts overall course points even when exam scores barely budge.
01Research in Context
What this study did
Leung et al. (2011) asked if short lectures help within interteaching. They split college students into two groups. One group got the usual interteaching prep sheets and peer talk. The other group got the same plus ten-minute instructor lectures before each unit.
What they found
Students who heard the mini-lectures earned more total course points. Their exam scores were only a little higher on two of five tests, but the overall grade boost was clear.
How this fits with other research
Schneider et al. (2006) showed plain interteaching beats full lecture. The new study flips the question: it asks if a small dose of lecture inside interteaching still helps. Answer is yes, so the two papers together draw a boundary—some lecture is useful, too much is not.
Reid et al. (2020) found long slide-only lectures tank trainee attention. Leung et al. (2011) kept lectures brief and embedded. Short plus placed inside activity equals gain without boredom.
Farnsworth et al. (2024) added a tiny online module and saw small etiquette gains. Likewise, Leung et al. (2011) added tiny live lectures and saw small grade gains. Both show bite-sized extras can nudge college skills.
Why it matters
You do not have to drop every lecture. If you already run interteaching, open with a five-minute recap of key facts. Keep it short, then let students debate. You may see the same small but real jump in total points without losing the engagement interteaching gives.

03Original abstract
Several studies suggest that interteaching improves student learning more than traditional lectures, but few have examined which components of interteaching contribute to its efficacy. We examined whether the lecture component of interteaching affected students' exam grades and cumulative point totals in a research methods course. Although students who received lectures had consistently higher exam scores than students who did not, the differences were statistically significant on only 2 of 5 exams. Students who received lectures, however, earned significantly more points during the semester.
