摘要：This work examines the effects of treating learners in a classroom to digital visual materials on ashared display, while interleaving such materials with scanned copiesof relevant textbook pages.Forty-six ninth-grade students in a public school in Bangalore (India) were divided into two groupsand given instruction in Science and Literature, the first group (control) being exposed to digitalvisual materials in both classes while the second (treatment) to the same materials interspersedwith digitally-scanned copies of textbook pages. Students in the treatment group outperformedthose in the control group on tasks involving recall and recognition of the visual materials(although the gap was significant only for recall-based tasks). Our results suggest that digitizedversions of textbooks are useful in improving students' retention of visual materials utilized duringclassroom instruction
