A learner-centred approach puts students amidst the learning process and helps them become involved in that process. It provides an opportunity for students to choose and direct the course of the lesson. This approach is especially appropriate when dealing with ethical concerns that might be sensitive issues. When it comes to the sources for the development of teaching materials, the Internet provides numerous possibilities. Not only does it enable students to choose from a wide variety of topics but it also offers, for both teachers and students, a chance to develop their own up-to-date materials through which students improve their language skills. Nonetheless, teachers can help their students to become more autonomous and develop strategies for lifelong learning. The aim of this article is to provide ideas on materials development for teaching English as a foreign language to students of medicine and health studies and to link theory and practice in the Slovak context. Specifically, it focuses on how topics in medical ethics, such as organ transplant and euthanasia, could be taught by emphasizing the learner-centred approach. Involving the student in the learning process and using the Internet as an easily accessible source enables students to develop their skills and strategies, which will help them become more autonomous, and thus develop their confidence in dealing with authentic English outside the classroom.
