Presents a self-administered computer spelling test that provides a detailed analysis of a student's spelling errors. (Available from: Modern Learning Publishers, Inc., 6517 Liggett, Oakland, CA 94611, $14.) (AEA)

The need for developing a technology of teaching that equals current sophistication of microcomputer technology is addressed. The importance of principles of learning and behavior analysis is emphasized. Potential roles of stimulus control and precise error analysis in educational program development and in prescription of specific learning…

Computer usage by preschool children differing in cognitive tempo was explored. Cognitive tempo refers to a child's tendency to respond slowly or rapidly in a problem-solving situation which has high uncertainty. The Kansas Reflection-Impulsivity Scale for Preschoolers (KRISP) was administered to 13 children enrolled in a prekindergarten class at…

Using Logo to work through a maze is described. Suggested programs to help students learn to debug programs are also included, along with the story of the original "computer bug." (MNS)

By handling numbers in unexpected ways, computers and calculators create headaches for computer programers and set traps for unsuspecting users by sometimes producing wrong answers. Specific examples of such computer/calculator errors are discussed. (Author/JN)

Error analysis of 260 timed writings by secondary and postsecondary beginning and advanced students found that, regardless of the level of instruction or the type of equipment (electronic typewriter or microcomputer), an inordinate number of errors were associated with home key rows. (JOW)

Several examples of mathematical diagnosis using microcomputer software are presented, with possible future considerations suggested. Three limitations of the software are discussed. (MNS)

Identifies types and distributions of errors in text produced by optical character recognition (OCR) and proposes a process using machine learning techniques to recognize and correct errors in OCR texts. Results of experiments indicating that this strategy can reduce human interaction required for error correction are reported. (25 references)…

Why a computer error occurred is considered by analyzing the binary system and decimal fractions. How the computer stores numbers is then described. Knowledge of the mathematics behind computer operation is important if one wishes to understand and have confidence in the results of computer calculations. (MNS)

A computer program is given which will generate a list of descriptions of the items to which a student has responded incorrectly on the Keymath Diagnostic Arithmetic Test. It is designed for the TRS-80, Model III, with two disk drives. The documentation lists all required materials, describes the six options and how to use them, indicates the…

The use of the microcomputer in an interactive graphics mode offers exciting possibilities for mathematics and science education. Errors made with graphs are used to introduce ideas of what should be taught. Both understanding equations and graphing utilities are stressed. (MNS)

Efficiency of three discrimination training procedures was compared for 21 mentally handicapped children. Results showed that two programmed techniques (graded stimulus and prompt fading) did not differ significantly, but both were significantly superior to trial-and-error learning. (Author/CL)

The present study examined the effect of three modes of feedback on the seriousness of error types committed on a post-test. The effect of the feedback made on post-test errors was found to be differential and dependent upon the seriousness of errors committed on the pre-test. (Author/LMO)

Some limitations of computing with calculators and computers are described, with particular reference to typical computations which might be performed by senior secondary school students. Types of errors, the laws of number, and intermediate round-offs are each illustrated, with conclusions and implications. (MNS)

Numerical inaccuracies, which occur in many ordinary computations, can create serious problems and render answers meaningless. Cancellation and accumulation errors are described, and suggestions for experimentation are discussed. (MNS)
