Teaching English as a Foreign Language, Second Edition

3 What is the mode by which the teacher is teaching?
Is he using a purely oral/aural mode? Talking and listening?
Is he simply talking or is he using audio aids as well? a tape
recorder? radio? record player? Are there sound effects for
the pupils to listen to or is it just words? Or, is the teacher
using a visual mode? Is he using written symbols: written
words, and sentences and texts, numbers, diagrams, charts
or maps? or is he using things that represent reality in some
sense: actual physical objects, models, pictures, photographs
or drawings? Or is the teacher using a mixture of aural and
visual modes? Can they be disentangled?
