The student does not necessarily have to agree, but your first goal is letting her know that she can and will learn the material in her own way and at her own pace. For students with autism, attention deficit disorder or dyslexia, learning anything is an uphill battle. Maintaining confidence in their capabilities, having patience while teaching and using alternative teaching methods are vital in bringing out the students' strengths while improving their weaknesses.
Your next goal is to figure out exactly how the student learns through observation and parental interaction. Note how the student expresses himself and communicates to others. He could learn either in visual, physical verbal or written ways. Discussing his past with the parents, as well as what methods work best at home, also helps you to understand how to best extract the student's strengths.
This goal is critical in building a student's confidence in her abilities. Pointing out where she is smart, capable and unique alerts her to assets that can be used in situations where she may not be sure of her potential. Discuss with the student what she enjoys doing, what you observe her strengths to be and what she could work on.
After completing the previous goals, the final goal comes much easier than if it were to be tackled first. Use a teaching method specific to the student's way of learning and at his own pace. Remind him of his strengths and past accomplishments so he may make attempts at improving his weaknesses with confidence.
