Speak clearly and articulate your words correctly. Your student needs to learn how to speak English correctly, and by speaking low or mumbling, you take the risk that he will mishear you.
Focus more on basic conversation skills at first. Save punctuation, grammar, and complex sentences for the future. The goal is to empower your student with the skills needed to ask for help, apply for a job, or engage in a casual conversation.
Ask your student to read aloud from a book. Start with simple texts, including children's books, and slowly make your way up to newspapers, novels, and even the encyclopedia.
Play video clips from TV shows, movies, and the news. Make certain you enable subtitles. This will allow your student to hear and read English being practiced in its conversational form.
Give your student an English to foreign language dictionary based on his native language. Teach him how to use it when needed, but encourage him to first try to find the meaning of a word based on context alone.
Encourage your student to participate in activities that will expose him to English speakers. This can include signing up for an extracurricular activity, chatting on social networks, and hanging out with English-speaking friends.
Engage in debates and topic discussions. This will help the student learn how to express his opinion in an eloquent and persuasive manner. This will in turn increase his confidence and make him more comfortable with the English language.
Play word games like Scrabble and Boggle. They are fun, educational activities that your student will enjoy. In addition, they'll force your student to learn new words and use his dictionary.
Be adaptable. If a lesson plan isn't working, then try something else. People learn in different ways, so you must be able to adjust your methods to fit the learning style of your particular student.
Assign homework and repeat everything many times. Learning a new language requires a lot of rote work. Otherwise, a student is likely to start forgetting things he has learned.
