We present the concept of instructional program coherence and explain why school improvement frameworks that incorporate instructional program coherence are more likely to advance student achievement than multiple, unrelated efforts. We present evidence that Chicago elementary schools with stronger instructional program coherence make higher gains in student achievement. We also share observati...

It is of course very difficult to accurately project important characteristics of the future state of any rapidly evolving field, and the field of authoring systems for computer-assisted instruction (CAI) is no exception. However, strong trends in evolving CAI systems of today would seem to indicate some important characteristics of the software systems underlying tomorrow’s automated instructi...

After several decades of learning research and the reactions of cognitive psychology to this research, educational psychologists and training designers developed prescriptive model for the systematic design of instruction (Derry and Lesgold, 1994). This model, called Instructional Design (ID) or Instructional System Design (ISD), consists of knowledge, terminology and procedures that are widely...

The Experimental Advanced Design Advisor (XAIDA) is a system for the development of computer-based maintenance training. XAIDA acquires knowledge of a device from a subject matter expert and applies common maintenance-training procedures to generate interactive training from the description. XAIDA provides maintenance training in four areas: the physical characteristics of a device, its theory ...

The Multi-channel learning environment is nebulous and incidental configuration where channels reinforce as well as contradict each other. The Multi-channel learning system is a deliberate, planned configuration to create the sync and synergize the power of various media to achieve optimal learning. This articles examines instructional design for the classroom, for self instructional materials,...
