In this step the students are introduced to the new vocabulary phrases for the lesson. There is no set number of new items to be introduced in a given session; however, three is generally considered the maximum number that can be effectively taught in a lesson. Limiting the phrases like this allows the teacher to focus on them and provide many repetitions for the students. This emphasis on thoroughly learning new material is designed to give the students a feeling of confidence and to provide sufficient repetitions to facilitate acquisition (unconscious control in recognition and output) of the new items.
