Previewing a text is a key global reading strategy. Previewing may increase comprehension as it can activate schema, increase global awareness of the text, and enhance the use of other reading strategies. Despite its importance, an explicit focus on previewing skills has been lacking and previous research on the reading strategies of second language (L2) learners' has largely relied on surveys. This study utilizes eye tracking technology, in addition to surveys, to evaluate the previewing strategies of Japanese L2 readers of English. The eye movement data revealed that most learners did very little previewing of the text. One measure of previewing significantly correlated with learners' summary protocol scores, which were poor overall. Finally, the eye movement data did not correlate strongly with participants' survey results. Implications for both reading education and research are discussed.
