Teen2Teen provides a comfortable balance between a traditional grammar syllabus and structured listening and speaking practice. This four-level American English course for lower secondary is supportive for both the teacher and the student. Presentation of new language (target grammar and vocabulary) is simple, coherent, transparent, and explicit. Rubrics are written in clear language, reducing the amount of students’ first language in the classroom. The grammar syllabus is very carefully paced, allowing students to grasp key areas before moving onto more challenging structures. The course recognizes that typical classrooms contain large mixed-ability classes and sometimes few resources. Teen2Teen offers an easy-to-use unit structure, allowing for minimal teacher preparation time. More experienced and confident teachers can customize their classes with additional practice and features such as the Chat, an optional extension activity in which students take turns reading their personalized versions of a conversation model with a partner. Vocabulary, grammar, and social language are continuously reinforced throughout each unit (not merely presented independently), offering multiple opportunities to practice the target language and increasing memorability. A particular feature of the course is its teen appeal. The content reflects the way teenagers live and communicate; their likes and dislikes; their friends; their dreams and aspirations; and their curiosity to learn about the world. The natural, social language models and conversations, and the Teen2Teen fictional social network site feature mirror the way today’s teenagers communicate with each other in the real world. Unit and reading topics have been chosen to appeal to teenagers, as have the brightly coloured photographs and illustrations. The course does not assume existing linguistic, world, or cultural knowledge. New concepts are taught explicitly, using visual cues and definitions. Cross-curricular work is presented in the form of optional reading lessons covering geography, science, social studies, art, and other subjects, and accompanied by projects which enable students to extend their knowledge of the curriculum area in English. Teacher Resources include extra Grammar, Vocabulary, and Reading worksheets, Interactive Grammar Presentations, Vocabulary Flashcards for drilling, editable Tests, a Grammar Bank of supplementary grammar exercises, and Puzzles.
