The present study investigates the effectiveness of question paraphrases in supporting students' understanding of a specific task. Secondary school students (i.e., eighth grade) read two texts and answered several questions while texts were available. A paraphrase including core information about each question was included before students provided their answer. Individual differences in reading comprehension explained the beneficial effect of paraphrases. Concretely, the presentation of paraphrases improved the performance of less-skilled but not skilled comprehenders. These findings are discussed in terms of the processes involved in task model formation and individual differences underlying these processes.
