In hard disk drive, investigative newshounds Wallace and Erickson keep on with Gates from his days as an unkempt thirteen-year-old machine hacker to his present-day prestige as a ruthless billionaire CEO. greater than easily a "revenge of the nerds" tale although, it is a balanced research of a company triumph, and a stunningly pushed character.

9, p 32] But the computer environment introduces a renewed perspective inducing a change in both students' attitude towards mathematical content and expectations towards the teacher. Various roles can be mentioned with respect to the teacher's pedagogical implication in the IT classroom (see for instance [8, pp 27, 88, 97] or [10, p 84]): acting in tum as manager, task-setter, guide, Roles and needs of mathematics teachers 31 accompanist, coordinator, explainer, counsellor, leader, resource, and even as a fellow pupil (working on a task alongside the school students).

The domain which is the most out of reach without a doubt, is the one of the language and even more that of the dialogue. Therefore, a great deal of time has been lost and much energy spent on a problem which is, in the end, technical and marginal, that is the analysis of responses coming from the learner. There is an additional illustration of the false importance granted to this type of use. Many proposals of evaluation of the CAL products are made by observing and judging what the computer does and not what the teacher or learner does.

No vagueness, nothing implicit is allowed, even in educational software tutorials. The designer must therefore have considered beforehand the dialogue which is going to constitute the learning but only has access to only one of the two protagonists. It is only possible to write the role of the computer with all the subsequent responses to all the predictable reactions of the learner. The problem is therefore no longer to teach but to make the machine teach; this machine tutor is particularly limited.
