Preparing a course can be time consuming, so we need to be strategic and check what is available. Whilst many materials are not produced having the needs of international students in mind, we can easily adapt them. The Economics Network online learning and teaching materials site is a great resource base that provides reference lists, links to sites of interest, lecture slides, worked examples, multiple choice questions and answers, examples and activities for seminars.
Can we make a slideshow more clear in any way? Can we rewrite the learning outcomes in terms of direct questions that will be addressed during the lecture? Is there a clear summary? Can we choose slides from different presentations and can we make changes so that they become more visually interesting? Can we introduce current international issues? Can the language used be simplified?
Do not be apologetic about adapting materials, but acknowledge the sources and recognise the privilege of having access to such a wealth of resources.
