2 out of the 100 are interdisciplinary studies. From an employers view; I would must rather higher someone who knows not only how to teach, but knows information about science, English, health etc.
Knowing this it seems false, my grandmother graduated years ago with an interdisciplinary studies degree and now stuck in her job with no chance for advancement because of her degree and other jobs that she applies to will not take her because they feel her education is inadequate for the job.
