At present the prevailing pedagogical assumptions in translator training programs are (1) that there is no substitute for practical experience — to learn how to translate one must translate, translate, translate — and (2) that there is no way to accelerate that process without damaging students' ability to detect errors in their own work. Faster is generally better in the professional world, where faster translators — provided that they continue to translate accurately — earn more money; but it is generally not considered better in the pedagogical world, where faster learners are thought to be necessarily careless, sloppy, or superficial.
This book is grounded in a simultaneous acceptance of assumption (1) and rejection of assumption (2). There is no substitute for practical experience, and translator training programs should continue to provide their students with as much of it as they can. But there are ways of accelerating that process that do not simply foster bad work habits.
