Basically, the program is not flexible as only one answer will satisfy it. Communicative CALL will allow the student to explore the subject matter. Here again, there is a partial success. Students can even skip around within the lesson. These are only superficial forms of flexibility.
Students are very limited on what they can explore.
Communicative CALL will create an environment in which using the target language feels natural, both on screen and off. To me, this never appeared. There was no natural feel to any of the material. In the Oral lesson, what at first sounded like a conversation turned out not to be so as the voices were not consistent nor where the pictures. All the drills could be fill in the blank with the answer written on a space next to the sentence.
