Writing in English (or ‘WREN’ for short) is primarily aimed at university/university-college students who wish to develop their English writing skills across a range of genres at an advanced level. The textbook provides detailed guidance on core writing skills (note-taking, paraphrasing, cohesion and register) and covers a range of academic and non-academic genres (summary, abstract, essay, research paper, review, letters and emails). A section on accuracy addresses problems of expression and punctuation, including common pitfalls for students whose mother-tongue is Dutch. The chapters also provide tips on using GenAI tools as a writing assistant. The textbook is completed with a battery of exercises to help students bolster their skills for effective written communication. Solutions to the exercises can be accessed on the eCampusLearn platform after entering the individual code in the textbook.
