Practising teachers in infant and junior schools will first be concerned to make the best use of the books and reading materials in their schools, and to supplement this with home-made and commercially prepared apparatus as funds allow. Teaching machines may have a place in the classroom but the initial expense and their servicing and maintenance are not inconsiderable problems. There are plenty of technical books on the teaching of reading to which reference can be made for detailed techniques or extra ideas for classroom activities. Radio and television both these media if well prepared for and intelligently followed up have a place in the primary school. Cassette tape recorders are specially useful in normal classrooms—and very young children handle them with ease and confidence. Materials and apparatus need critical assessment. The cost of buying an item must be set against the cost of raw materials and the time involved in making it.
