The multiple-choice questions on the RRMCS were developed using student ideas from demonstration-based interviews. The questions were revised through expert review, additional student interviews and analysis of results after giving the test to a large number of students. Appropriate statistical analyses of reliability and discrimination were conducted, and the RRMCS was found to have good reliability and discrimination. The RRMCS has been given to over 3000 students in algebra-based, calculus-based, honors and upper-level courses and the results are published in one peer-reviewed publication.
The average test scores in non-honor introductory (n=669) and upper-level (n=17) classes ranged from 44% to 61%, while a class of freshman honor students (n=93, required to have a QPA of 3.5 or better) scored 75% on an average.
