This paper examines whether and how L2 learners’ reading strategies vary depending on the task type or on the measure of eliciting strategy use. Participants were 28 college students in a Korean university. Two reading tasks (i.e., reading for comprehension vs. reading for summarizing) and three measures of strategy use (i.e., pre-reading strategy survey, while-reading think aloud, and post-reading strategy check list) were employed to answer the posed research questions. The researcher’s observation of the participants’ thinking-aloud and a post-task interview were also implemented for data triangulation. All the participants completed two tasks based on two texts (one for each) selected from the same chapter in a book that were considered equivalent in length, readability, and topic. The results revealed that the number of reading strategies reported decreased dramatically in the order of strategy survey, strategy check list, and think aloud. Significantly more frequent use of reading strategy was found in reading for comprehension than in reading for summarizing, large portion of which was devoted to bottom-up style decoding, while in reading for summarizing the students approached the text with more focused attention caring about propositional connections at discourse level. Some other findings are presented along with implications for reading research and for L2 reading instruction.
