All middle school teachers in North Carolina have to teach physical science, which is required for middle school students in NC public schools. Unfortunately, over 80% have never taken a physical science course and many of those who have, have taken a course that is of no help to their students. Naturally, with their limited backgrounds, they hare heavily dependent on the materials they are given to teach from. In addition, in many instances these materials form the teacher’s own introduction to the subjects. It is especially important, therefore, that the textbooks and other materials that teachers and students are forced to use get it right.
