This was my problem but I managed it by explaining the lesson in English and use my body (this is a tecnique in teaching English) to let them get the meaning of the new words ,during the the lesson I may use the Arabic if I feel it is needed to get the full meaning . The important thing that I always ask for the preparation at home and check it with marks and gifts ,I even bought them dictionaries .I always ask them to say easy sentences loudly with marks or gifts in front of other students . Day after day you will notes the changes but you have to be a wide-hearted teacher .
sorry for being talkative , I wish you all the best .......
