CBI requires better learners as well. Students are hypothesized to become autonomous and independent in CBI, so that they are conscious of their own learning process and can take charge of their learning. Furthermore, students are expected to support each other in collaborative modes of learning. Finally, students need to make commitment to this new approach to language learning (Stryker & Leaver, 1993). Typically, the materials in CBI are used with the subject matter of the content course. It is recommended that “authentic” materials are identified and utilized. There are two implications of authenticity. One implication is that the materials are similar to those used in native-language instruction; the other relates to the use of newspaper and magazine articles and any other media materials “that were not originally produced for language teaching purposes” (Brinton et al., 1989). Some realia such as tourist guidebooks, technical journals, railway timetables, newspaper ads, or TV broadcasts are also recommended by many CBI practitioners (Richards & Rodgers, 2001).
