Acording to Professor Adey (March 2 "In Need of Second Thoughts") the intelligence of 12-year-olds can be increased by particular methods.
But isn't intelligence a rather controversial topic, subject to manynbsp;variations?
Claiming that one group of learners is better or worse than average doesn't explain five years of secondary education that leads up to the GCSE examination.
Can Professor Adey discuss the "intellectual challenges" he enjoyed so that the "theory" deployed in resolving those challenges is plain to TES readers? His argument assumes coherent sets of pupils awaiting the right teaching approach, rather than heterogeneous individuals who have some freedom of choice when deciding what counts as "interesting" challenges.
