|Abstract Title:||Surveying Students' Understanding of Measurement Uncertainty and Proportional Reasoning|
|Abstract:||As part of our NSF-supported curricular development efforts to create course materials to enhance the scientific literacy of undergraduate non-science majors, we are developing a survey instrument to probe this population's understanding of measurement uncertainty and proportional reasoning ability. By employing everyday items (scales, luggage, and kittens) and activities (weighing oneself and traveling) we have attempted to create an interview instrument and protocol that evokes and accommodates a wide range of responses and interpretations.
Although still in the development phase, we can report that our population has a very difficult time applying measurement uncertainty and proportional reasoning, even after instruction designed to improve those principles.
