Marc Brysbaert and François Dumoulin argue that there are several reasons for lecturers in Dutch-speaking countries to adopt Dutch textbooks instead of English (American) textbooks in undergraduate courses, in particular in introductory courses (Brysbaert & Dumoulin, 2007). They present three arguments to support their case. First, they point out that, relative to Dutch textbooks, English textbooks enhance the workload of students, which they believe is undesirable. Second, they claim that language switching associated with the use of an English textbook brings with it unwanted costs. Finally, they state that English (American) textbooks are too oriented towards the American culture at the expense of the Dutch-speaking part of the world.
