We are writing to you to introduce the new edition of Focus, our five-level course for upper secondary students. As writers, it is always a privilege to be invited to ‘have another go’ and we are grateful to our publisher Pearson for giving us this opportunity. At the same time, we are particularly wary of introducing change for change’s sake. ’If it ain’t broke, don’t fix it’ is a maxim we set great store by. In our own classrooms, we are still using ideas and teaching techniques that we learnt early on in our careers. Why? Because they still work.
