Interchange Intro Lab Cassettes

The Intro Lab Guide and Lab Cassettes are designed to give students additional practice in listening comprehension, pronunciation, grammar, vocabulary, and oral fluency. They are suitable for use in the language laboratory, in the classroom, or for self-study. The Lab Guide supplies tapescripts of the material on the cassettes and offers flexibility by providing three different levels of support for students. The cassettes can be used on their own or with the support of the Lab Guide.
