The document discusses how the interactive whiteboard (IWB) can be used to enhance the teaching of grammar in context. It explains that grammar is best taught as part of language instruction, not in isolation. The IWB allows teachers to highlight and annotate texts to draw students' attention to grammatical forms, functions, and usage. It also facilitates manipulating texts and interactive activities like clickers to help students understand meaning, recognize structures, and produce language with appropriate grammar in context. A variety of techniques are presented, such as highlighting, rearranging words and sentences, adding or removing text, and reviewing materials on the IWB.
