Instructional transactions are Instructonal algorithms, patterns of learner interactions, usually far more complex than a single display and a single response, which have been designed to enable the learner to ecquire a certain kind of knowledge or skill. Different of kinds of knowledge and skill would require different kinds of transactions. The necessary set of these instructional transactions is designed and programmed once, like other computer applications, such as spread-sheets. They can then be used with different content topics as long as these topics are of a similar kind of knowledge or skill. A transaction shell is the structure of a transaction identifying the interactions, parameters, and knowledge representation needed for a given class of transactions. A transaction shell is a piece of computer code that, when delivered to a student via an appropriate delivery system, causes a transaction to occur. A transaction shell consists of two subsystems: an authoring environment and a delivery environment. The users of the authoring environment are subject matter experts and instructors; the users of the delivery environment are students. The authoring environment has a knowledge acquisition system as a transaction configuration system. The knowledge acquisition system queries a subject matter expert concerning the knowledge and skill required by the enterprise. This information is organized and stored in a knowledge base. The transaction configuration system enables the instructor, or designer, to provide values for a wide range of instructional parameters. The parameters control the nature of the interactions with the laerner. Instructional parameters enable a given transaction shell to be customized for a particular stodent population, learning environment, and learning tasks. The instructional delivery environment provides the actual interactions with the student, as enabled by the transactions, controlled by the instructional parameters, and using the knowledge and skills represented in the knowledge base.
