Welcome to English Lessons. All of these lessons integrate activities for language exchanges into English lessons posted elsewhere including LearningEnglish from the British Council and Learning English from the Voice of America. The goal is to demonstrate how use language exchanges as part of a structured sequence that practice all four linguistic skills: reading, writing, listening and speaking. Once you've done several, you'll be able to use readings or videos from around the web to form the basis for future language practice as well.
Each of the videos from the British Council include links to grammar explanations. Your language partner may not be able to help you with explanations regarding grammatical structures. If you find structures you do not understand, try OWL from the University of Purdue. If you can then give your partner a few examples from the OWL guide, they are more likely to better be able to explain when the structure is used and accurately correct your mistakes.
In addition to the grammar, I would also encourage you to make a note of new words as you learn them. Sites such as Quizlet will let you create flash cards so that you can quiz yourself later.
Note as well that at the end of each lesson there is a link allowing you to request a "confirmation" from your partner. This is entirely optional. If you do so, you will see a list of each lesson completed on your profile page. If you are using the Mixxer as part of a traditional class, your instructor can then track your progress.
