First, research shows that incidental exposure to written texts can do more to improve one’s lexical knowledge than instructional programs for teaching vocabulary. In other words, being able to read in a foreign language contributes drastically to the learning of that language. Second, many contexts in which language learners find themselves require them to interact with written texts in order to succeed. But even foreign students who meet the language criteria for university study are slower in processing the language and show more limited comprehension, which limits what they can achieve. Improving the reading fluency of foreign learners of English, and of English learners of a Modern Foreign Language, will be hugely beneficial to the students, the academic institutions and the UK as a nation.
