Evolution by natural selection may be characterized as a system in which a large store of genetic information will persist indefinitely while it remains coordinated with its environment but will continuously produce small random variations that are tested for environmental effectiveness. In any environment, effective variations will persist while ineffective variations will disappear. Similarly...

This paper presents an evaluation of the instructional text generated by Isolde, an authoring tool for technical writers that automates the production of procedural on-line help. The evaluation compares the effectiveness of the instructional text produced by Isolde with that of professionally authored instructions, such as MS Word Help.

Kirschner, Sweller, and Clark (2006) make a general case for the effectiveness of a teaching method—direct instruction—without reference to any context of what it is that is being taught by whom and to whom. In so doing, they bypass what is arguably the most pressing concern facing educators—not how to teach students but what to teach them. An argument is made for the need to contemplate instru...

This paper describes a study conducted in recognition of the increasingly widespread use of computers and the importance of exposure to instructional technology (IT) in all aspects of the poultry science curriculum. The study consisted of the distribution and analysis of two cross-sectional surveys. One survey was sent to departments to obtain profiles of poultry science degree programs and the...
