As it has been said before, second language teachers should select carefully the instructional materials used in the process. Furthermore, it has been said that they should be created by the teacher because in this way they are properly contextualized and fit the needs of the students.
What istructional materials should have? there are some principles that a teacher must follow when designing or selecting materials. First, materials should have certain elements that motivate the student to learn, those elements should be positive expectation that include a good climate and activities that help the students' improvement properly contextualized; feedback, that is very important because in this way the students notice their progress and are aware of their learning process and then, the appearence of the materials. They have to look attractive but complete; that is, they have to be meaningful for the learner. Second, the instructional materials should throughly teach a few important ideas, concepts or themes. These ideas help the learner to have the picture of what the topic is about. Third, The materials must contain clear statements of information and outcomes. For this principle, explicit instruction is relevant since it clarifies direction and explanations and ambieguity is excluded. Fourth, instructional materials must include guidance and support to help students safely and successfully become more independent learners and thinkers. This is that the students obtain the guidence and support in the needed levels to improve their language skills. Finally, Instructional materials should include instructional and assessement strategies that make the students successful learners. Those strategies must be aligned correctly and completely enough.
