Inside Writing takes a genre approach to writing. Students learn how to write different text types, for example, newspaper articles, persuasive essays, and summaries. This approach enables students to write for different audiences and purposes effectively.

Writing techniques, including analyzing audience, providing a hook, and using correct register, prepare students for academic writing. Writing models show examples of authentic academic text types and allow students to analyze what makes a text effective before creating their own. Grammar and vocabulary instruction ensures students are good writers on both sentence and essay level.

Inside Writing helps students to acquire vocabulary from the Academic Word List by systematically incorporating AWL vocabulary across all five levels. Students first encounter the unit vocabulary words in a pre-unit self-assessment exercise, enabling them to check how familiar they are with the vocabulary they will encounter in the unit. These words are highlighted throughout the unit, meaning that students can learn them in context. Based on a corpus of 3.4 million words, the Academic Word List (AWL) is the most principled and widely accepted list of academic words.

Example sentences from the Oxford English Corpus teach real-life English, based on authentic texts. The Oxford English Corpus is based on a collection of over 2 billion 21st Century English texts. The sentences taken from the corpus demonstrate the most frequent and salient use of a word, meaning that students learn to produce authentic English in use.
