Examination performance in lecture-discussion and personalized instruction courses.

The researchers compared two ways to teach a college course. One class got the usual lecture. The other used personalized instruction, where students move at their own speed and must pass small tests before going on.

Both classes took the same final exam. The team looked at total scores and at different question types.

The personalized class earned higher exam scores. The biggest jump showed up on written-response questions. Students who had been low achievers before gained the most.

Hoffman et al. (1969) ran a similar PSI course three years earlier and saw the same lecture-beating result, so the new data act as a friendly check.

Navarick et al. (1972) zoomed in on one PSI part: proctoring. They found that even light proctoring helps, and heavy proctoring mainly makes students finish faster, not score higher. Brown et al. (1972) kept the proctoring level the same across groups, so the two papers fit like puzzle pieces.

Born et al. (1974) tracked study time and showed PSI kids learn a bit more while working the same total hours, backing up the claim that the method is efficient, not just effective.

If you teach older learners, swapping long lectures for self-paced units with quick checks can raise test scores without extra class time. Start small: turn one weekly lecture into a short reading plus a five-question mastery quiz. Watch who finishes fast and who needs another try; both groups usually score better on the next exam.
