What limits the encoding effect of note-taking? A meta-analytic examination

Previous meta-analyses indicate that the overall encoding effect of note-taking is positive but modest. This meta-analysis of 57 note-taking versus no note-taking comparison studies explored what limits the encoding effect by examining the moderating influence of seven variables: intervention, schooling level, presentation mode and length, test mode, and publication year and source. It was found that (a) either positive interventions or rise in schooling level did not enhance the benefits of note-taking; (b) visual presentation of learning material interfered with the note-taking process, whereas longer presentation did not; (c) recall test detected the encoding effect more than recognition and higher-order performance tests; and (d) publication year and source contributed to the variation in effect sizes. These results suggest that the modest encoding effect is not due to the incompleteness of students' spontaneous note-taking procedures, but mechanical demands of note-taking, type of learning outcome measure, and publication characteristics.
