M. F. Cleugh 
Teaching the ‚Slow‘ Learner in the Special School [PDF ebook] 

This book is a re-issue originally published in 1961. The language used is a reflection of its era and no offence is meant by the Publishers to any reader by this re-publication. Dr Cleugh was in charge of the course for teachers of so-called ‚educationally sub-normal‘ children at the University of London Institute of Education.This work, an up-to-date guide at the time, was written by practising teachers who had passed through the Institute’s course, and covers every part of the curriculum from the point of view of the ’slow‘ learner.
