World English is an exciting new four-skills program which uses National Geographic content, images, and video to teach the language that learners need to succeed in their daily lives. The series is built upon clear and practical learning goals which are presented and practiced through appropriate themes and topics. World English uses real people, real places, and real language to connect English language learners to the world. Each level in the World English series is accompanied by World English Writing Portfolio which is specially written to develop learners writing skills from basic word and sentence formation to writing connected paragraphs in a variety of writing contexts.
