Talking is the single most important way to communicate. People do it everyday whether it be talking on the phone, face to face or even sign language. This is how people communicate in everday society. Without talking I don't think we would be able to function as a whole, nobody would know what to do and the children wouldn't be able to learn what they need to because there is no communication.
Talking is very benifiacial in the classroom because it is a way to communicate something new to children. You have to talk to teach and the children can't just be quite all day so they have to be able to talk also. Talking is also very benificial in group assignments, the children are able to talk to one another and help each other out. For instance, if one child doesn't get exactly what is going on another person in the group could maybe explain it better in a way the child can understand.
Talk in the classroom for example could be asking the students, "What do you think about this?" or "What would you do in this situation?" Asking questions such as these one gives the children a chance to express their opinion and to gives them a chance to communicate with one another creating a discussion that could help them better understand the lesson. Asking open ended questions involves the students and allows them to talk with one another so they can express there own opinion and be able to communicate with other classmates and the teacher.
