A large amount of data becomes \"Big data\" when it meets three criteria: volume, variety and velocity, data in a vast, partially structured data set. The development of computerized learning modules enables assessment of students in systematic, real-time ways. Data mining and data analytic software can provide immediate feedback to students and teachers about academic performance. That approach can analyze underlying patterns in order to predict student outcomes such as dropping out, needing extra help, or being capable of more demanding assignments.
