Delay of self-testing in three types of programed text.
Wayne A. Hershberger, Donald F. Terry · Journal of Educational Psychology · 1965
This study compared three intervals of delay (corresponding to the times required to read several words, paragraphs, or pages) between initial reading and subsequent self-testing for recall, in three types of programed texts. One type of text permitted the subject to reread before answering (Preview), another after answering (Review), and a third type exposed the correct answer after the subject responded (Confirmation). Three matched groups of pretested sixth graders, 55 in all, read the three types of programs and took a posttest. Both variables, program type and delay interval, affected program errors but neither affected gain scores. However, all delay intervals of self-testing were superior to no self-testing. Related research was reviewed from a cybernetic viewpoint. (Author)
