1) The structure of most common Mathematics textbooks according to Johansson
(2003) is ‘exposition –examples – exercises’ model (which this study called 3es), In the
exposition part the author supports and clarifies concept formation by the student. It makes a
sequential guide to discovery. This is followed by examples. Lastly, the exercises stage, these
exercises are graded and they progress from the easier to the more difficult(Love and Pimm,
1996) just as the examples are in hierarchy of grades,. However, in an old study of German
textbook, there was about twice as much text as task reported by Sträβer (1978).
