The paper “Automaticity in Computation and Student Success in Introductory Physical Science Courses” is available as a PDF from the ArXiv site at no cost.
The article compares US math standards in place in most states until about 2012 (with impact on most current US students) to the recent findings of cognitive science on how the student brain solves problems. The impact of those standards on student preparation for quantitative science courses is discussed.
