1. 任务教学是在前苏联心理学家Vygotsky等人的语言与学习理论基础上,由Willis设计出的一种教学模式。该教学模式是以完成任务为主要教学形式。在“任务型”课堂上，学生始终处于一种积极的、主动的学习心理状态。根据不同层次的学生的水平，创造出不同的任务化活动，让学生通过学习伙伴合作、协商去完成任务。学习过程充满了反思、顿悟和自醒，从而可以最大限度地调动学生的学习内驱力，提高学生发现问题、解决问题的能力，发展他们的认知策略，培养他们的合作精神和参与意识，并在完成任务的过程中体验成功的喜悦，充分发挥自身的潜能。本节课以学生为主体、教师为主导，引导学生积极运用英语进行交流并完成一篇小文章。
2.创设合理的情境。创设情境教学既能活跃课堂气氛,激发学生的学习兴趣,锻炼学生的语言能力,又能培养学生的思维能力和空间想像能力。创设与学生生活有关的情境，让其在轻松熟悉的环境中学习。
3.合作学习。通过合作交流和相互改正，提高学生的集体荣誉感和合作精神。
