Classroom Second Edition by Donald H. Ecroyd. In the classroom to teach is to talk and to learn is to listen, the classroom in other words is full of  oral interaction. Every classroom teacher is a speech teacher wether he/she wants to be or not, for learning, listening, teaching, and talking cannot be separated. This book is directed to the teachers in training,  its aim is really two-fold, first it is designed to help develop those speaking skills which are  so much a part of the teachers daily profssional work, and second it is planed to give insight into the kind of speech problems that elementary and secondary students face. To his students and to himself as well, every teacher owes his best possible communication skill.
