I. What Does AuthorIT Mean for Developers/Researchers?
Faster More Cost-Effective CBI Development Content – use AutoBuilder to define what is to be learned Interface – use Blackboard Editor to define user interface
in easy to use GUI Delivery – use Option Tool (dialog box) to specify one or
more ways for content to be delivered Delivery – TutorIT delivers content to learner in any of the
specified ways (e.g., to conduct definitive research)
Integrated Development Platform Means Quality Control / Uniform Quality
II. What Does AuthorIT Mean for Developers/Researchers?
Greater Precision To be acquired knowledge can be
represented at whatever level of precision may be desired
Analysis is cumulative – continued as resources allow
Diagnostic precision & tutor effectiveness – increased as resources allow
Utopian goal of guaranteed learning becomes attainable
III. What Does AuthorIT Mean for Developers/Researchers?
Single Development Cycle –
Multiple Products
Instruction – delivers instruction systematically in optimal order
Diagnostic – quickly determines what learner knows Adaptive – automatically adjusts testing & instruction in
optimal fashion Simulation/Performance Aid – Guides learner step by
step in performing tasks Practice – provides practice on important material

What Does EZauthor Mean for Developers/Teachers/Trainers?
EZauthor “Short Cut” for Simple Tutors
Build adaptive tutors with absolutely no programming
Automatically concentrates on what learner does not know - e.g., learn a language more efficiently)
Leading CBI Developer Estimates* Development Times
Tutorials – 200 hours per 1 hour of instruction
Simulations, Games, Intelligent (adaptive) Tutors – 200-800 hours per 1 hour instruction
Non-interactive – 100 hours per hour of instruction
Allocation of Time 1. Front end analysis - 20% 2. Instructional Strategy Definition - 30% 3. Creation of Media and software assets - 20% 4. Integration of components and testing - 30%
* Foshay & Preese, Technology, Instruction, Cognition & Learning, 2005.
Estimates with AuthorIT Development Times
Tutorials – 20-100 (vs. 200) hours per 1 hour of instruction
Simulations, Games, Intelligent (adaptive) Tutors – 20-400 (vs. 200-800) hours per 1 hour instruction
Non-interactive – 10 (vs. 100) hours per hour of instruction
Allocation of Time 1. Front end analysis – no change (20%) 2. Instructional Strategy Definition – (1% vs. 30%) 3. Creation of Media and software assets – no change (20%) 4. Integration of components and testing – estimate continuing
reductions as system matures to (5% vs. 30%)
