Discusses and defines immediate and delayed feedback as they apply to computer-assisted instruction and testing. A research classification matrix is presented to provide a framework for classifying existing feedback studies and to guide future research, and a sample bibliography classified according to the matrix is given.

An alternative approach to the systematic design and development of computer-assisted instruction courseware by classroom teachers is described which consist of three main stages of design, development, evaluation, and revision. Each stage produces a usable output: (1) computer-assisted testing program; (2) drill and practice courseware; and (3)…

Describes the workings of computerized adaptive testing (CAT). Focuses on the key concept of information and then discusses two important components of a CAT system: the calibrated item bank and the testing algorithm. Describes a CAT that was designed for making placement decisions on the basis of two typical test administrations and notes the…

The evaluator is an instructional system product that provides practice, testing capability, and feedback in a way not yet seen in computer-assisted instruction. Training methods using an evaluator contain scenario-based simulation exercises, followed by a critique of performance. A focus on competency-based education and performance makes the…

Presents a rationale for future research relating to educational computing, discusses beneficial studies that have been undertaken, and outlines specific areas where further research is needed, including studies on achievement, retention, and transfer measurement; material characteristics which enhance achievement; implementation variables,…
