belief 1: students should be taught the variation of the language that they expect to be using, with other variations afterwards, as accurately as possible in order to develop good habits. When/if students are learning another variation of the language, they will have a foundation to base it on. If you teach them at the same time the students may end up confused.
practice a: correct mistakes early, to avoid them forming into habits.
practice b: allow and encourage pursuit of other forms of the language, but after the student has achieved "sufficient" mastery in the native one.
belief 2: Students need individual attention apart from group meetings.
practice a: If possible, teachers should meet with their students outside of the group setting, to work on difficulties that individual students may have, to let them feel more comfortable asking questions, and to speak about individual interests. This could help establish better rapport and heighten the student's confidence in the group setting. This should also allow for you to cater to the individual student's style of learning.
practice b: Ask student to keep a journal in which they can write about things that interest them, questions they have about what is being learned in class or english in general, fun times they've had, etc. Have them turn in their journals to you at the end of each week or so in order for you to read and provide feedback. Feedback here doesn't necessarily mean corrections,it can be just demonstration that they have your attention and you care about them.
belief 3: Teacher should use a variety of presentation methods taking in account different learning styles.
practice a: the teacher can in addition
belief 4: There should be high student involvement in class activities.
practice a: Aim to limit your grammar explanation times to 10 or 20 seconds.
practice b: Ask questions of your students frequently to keep them talking, plan activities that get them moving around
