Introduction
Vista University is known in South Africa as a historically disadvantaged or black university. It is a multi-campus university (it has eight campuses throughout South Africa) and caters for learners from historically disadvantaged backgrounds. The Department of Mathematics and Statistics holds an annual meeting to coordinate the activities in the department across all eight campuses. Attendance is compulsory for all lecturers from all the campuses. Every year the same problem arises, which is to have examination papers drawn up that will be of a uniform standard across all the campuses.
Analyse
Before any application is developed, it is essential to ascertain whether such an application is really necessary. During a meeting of the Department of Mathematics and Statistics (Vista University) it was decided that a database of questions must be developed and made available on-line. As one may expect, such a database of statistics questions already exists on the Internet: DASL claims to “provide data from a wide variety of topics so that statistics teachers can find real-world examples that will be interesting to their students” and the question arises whether the language of instruction (English) and the culture/background of the first-year Vista student can be seen as major obstacles with the result that they cannot identify with these « real-life » examples.
Comprehensive reading
In statistics the student must interpret the analysis done in terms of the problem. Most of the time the interpretation is written in disjointed, jumbled sentences. This agrees, even in 2001, with the findings of Lanham (1986): “…research shows that it is quite possible to go through the motions of reading and to apply the product of such reading by passing a conventional comprehension test based on a text which is actually nonsense; in other words, not really to understand the text.”
Graphics
The author also suggests that strategies to create background knowledge must be used: pictures, titles and event-orientated words in early sentences can help the reader to raise to a level of conscious awareness of the background knowledge needed for understanding the text.
