Materials development is concerned with all the resources available for helping the teaching and learning process. These resources include professionally printed products such as textbooks, activity books & teacher guides as well as CD-ROM, DVD, and online computer resources. Resources also include those materials created by teachers & students. In this course, we review various re- source options, discuss their advantages & disadvantages, and outline ways in which teachers can both use and create effective and efficient materials to help in the teaching and learning process.

In this course, we look at different methodologies for TESOL, with an emphasis on the theory, principles, and procedures of the Communicative Method. However, in practice, most teachers employ a range of methodologies.
