I have not hear of the Views of NOS Questionnaire before. I have used the CLASS and E-CLASS survey's that were specifically designed for assessing students ideas about the nature of physics and physics laboratory experiences, respectively, in post secondary settings. I believe there are varients for other contents as well.
One note is that assessments focus really on the percieved view of the field, so I am not actually sure how specific NOS activities, that might have students engage in the nature of science more broadly will affect the outcome. The research body on the CLASS suggestions that students views only become more reflective of the true nature of physics if they are in a course with investigative and inquiry based experience.
