A Parameter-based Statistical Algorithm for Math Items in Multimedia Education

Castle Rock Research provides quality curriculum-based educational resources to students, parents and educators, both online and in print. This project involves the design of a parameter-based statistical algorithm to automatically generate math questions for multimedia education applications. Rather than relying on a curriculum designer to create questions one by one, multiple questions can be generated by the algorithm. By varying the parameter values, the model is able to control the difficulty level of the questions. Different from the multiple choice question, where only “correct” or “wrong” can be awarded, this model is capable of scoring partial marks. The algorithm will be used in the Castle Rock Online Multimedia Learning and Testing System.
