Title:	BYU TestBank: An Automated System for Unique Test Generation and Correction
Author(s):	David G. Whiting*+ and Del T. Scott
Companies:	Brigham Young University and Brigham Young University

Keywords:	database ; testing ; instruction
Abstract:	We describe a system for automated test creation and correction that was developed throughout the past three years and has been implemented at Brigham Young University in both introductory and advanced statistics classes. Incorporating MySQL, R, Sweave, LaTeX, and a php web-based frontend, the system creates unique tests for students based on a database of question templates. Most questions have imbedded R-code, which allows for random generation of data values and correct answers. Thus, there are virtually an infinite number of tests that can be created. Instructors create tests by querying the database with one or all of the following: keywords, class number, chapter number, question difficulty, or test number. Students are provided with a pdf file of the test and, when a question requires, a web link to download data for that particular test. An online form also is provided for entering their test answers. Tests may be corrected individually upon submission with immediate feedback provided to the student, or the instructor may opt to correct tests for the entire class upon test completion.
