In "Making a logical assumption" (TES, May 24), Dr Marianne Talbot has made a convincing case for logic being taught as widely as possible.
The cross-curricular impact of a training in logic is clear. It involves both grammatical analysis and giving proofs with reasons.
Pupils who have studied GCSE logic and gone on the university to study mathematics, philosophy, computer science, physics, engineering, law, linguistics etc regard logic as an inspired choice from the GCSE options available to them. It is especially important for mathematics, philosophy and computer science. University teachers of computer science have asked why skills in logic are not taught in every school.
For 13 years I have been teaching logic (O-level and GCSE) in a large comprehensive school and listening to accounts from former pupils of the impact of this subject. Unfortunately, the examination boards have decided that it is too expensive to run a course without a profit-generating candidature and so logic has been axed. Profit maximisation and lack of vision have killed it. This summer's examination is the last.
