Recently, the ITT Technical Institute Nashville Campus began offering their General Education courses in an online format for incoming students. A strong possibility exists that some technical core courses will be offered in the future using a distance delivery method to minimize the amount of time students spend on campus. Investigation into different delivery methods is imperative for an adequate comparison, as well as determining which method, if any, would be better suited for the school and students alike. The focus of this paper is to determine the best instructional technology method to be used for the introductory computer-aided drafting and design course. The methods to be compared are computer-aided instruction, computer-based training and Web-based training.

Learning Drafting and Design Basics in an Online Environment: A Study Determining the Effectiveness
Within the last nine months, the ITT Technical Institute Nashville Campus began offering their General Education courses online to incoming and transfer students. When the online program officially began over a year ago, it was managed through another school and student information was sent to the ITT Technical Institute where the student was registered to take their technical core courses. Since that time, the online program has undergone a few revisions. The current instructional method,...
