Some units do not have every section, but the order followed is nonetheless similar. Such a strict organizational framework has distinct advantages. First, teacher and learners quickly become familiar with the process followed in each unit and in each type of exercise. Once this occurs, time spent explaining how to do a particular exercise is reduced. In addition, by consistently repeating the same cycle of material, learners grow to know what is expected of them both within individual exercises and throughout a given unit.
Clear expectations can, in turn, reduce confusion and enhance the learning process.
Ideally, teacher and learners work together to establish a rhythm that best suits the class. However, these advantages can become disadvantages if certain pitfalls are ignored. Although establishing a class rhythm is important and reassuring, a rhythm can easily become a routine engraved in stone. With any text that recycles format and material as carefully as Contemporary English does, teachers must guard against this happening. Too much routine can become boring and can discourage creativity, spontaneity, and fresh ideas from teacher and learner alike.
