Do students really prefer repeated rereading over testing when studying textbooks? A reexamination

Experimental studies have shown that testing promotes better long-term retention than repeated rereading. Regarding implications for educational practice, based on a survey study seemingly showing that students prefer repeated rereading over testing when studying [Karpicke, J. D., Butler, A. C., & Roediger, H. L. (2009). Metacognitive strategies in student learning: Do students practise retrieval when they study on their own? Memory, 17, 471-479. doi: 10.1080/09658210802647009 ], it has been concluded that increasing the number of tests may boost students' achievement. However, a closer look at the survey study reveals that "repeated rereading" has been operationalised in terms of "restudying" which represents a term that may subsume a variety of study strategies. We reexamined the study behaviour of students in a more fine-grained way by surveying both their hypothetical (Study 1) and real (Study 2) study behaviour when restudying texts. Results showed that rereading is preferred only by few students early in the learning process, with almost all shifting to testing late in the learning process, and that rereading is mainly performed in terms of "rereading not understood parts", and rarely in terms of "repeated rereading". These results indicate that the implications of the testing effect for educational practice may have to be reconsidered.
