Notion

A notion in English language teaching is a common concept such as movement, emotions, means of transport, work, health, distance, shopping, accidents, speed and an almost unlimited number of possible subjects with which to engage students.

The traditional approach to language teaching held that notions were necessarily aimed at teaching vocabulary, but these days teachers seem less dogmatic and more flexible in when, where and how to teach all the necessary aspects and skills students need to learn and practice in the target language.
