According to the results of PISA 2009, while girls are more proficient readers than boys in both print and digital media, it appears that the gap in performance is narrower in the digital medium. It has been suggested that the narrowing of the gender reading gap might be attributed to relatively strong navigational skill on the part of boys. This presentation will explore the evidence for this suggestion, and will also look at other possible reasons for boys’ relative success in the PISA digital reading assessment, including the types of texts represented in the assessment and the proportions of different item formats.
