English language fluency and the way Polish school students work with English textbook material on the example of two students

Eye tracker makes it possible to see where and how the person is looking. During the analysis of previously collected eye-tracking data my attention was drawn to two school students whose English language communicative skills were on different levels and that is why I assumed they should work with the English textbook material in a different way. The aim of the article is to show not noticed at the first sight differences in their way of working with the English textbook material.
