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…

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)

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)…

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)

Reports on the effectiveness of a theoretically based computer spelling program designed to help learning disabled students practice lists of words. The program employs a type of computer response called Imitation-Plus-Modeling. (AEA)

Seven graduate students in a seminar on classroom computing received instruction in LOGO programming. Programming protocols were collected periodically and examined for errors and misconceptions; in-depth interviews were conducted in order to understand specific misconceptions better. As novice students transit from instruction to experience in…

Noting that while the number of errors gives a general indication of spelling ability, it may represent an oversimplification of the spelling process, a study examined the spelling ability of 40 Canadian third grade students of average ability. Subjects were divided into low and high spelling ability groups on the basis of the Edmonton (Alberta)…

Recall of multiplication number facts is a major educational objective in elementary grades, yet some children never acquire total mastery. A microcomputer multiplication number facts training program was developed which incorporated programmed instructional features including feedback, positive reinforcement, vanishing, branching and pairing.…

These proceedings include two lectures followed by working group and topic group contributions in reduced format. The two lectures were by Heinrich Bauersfeld, speaking on contributions to a fundamental theory of mathematics learning and teaching, and Henry Pollak, speaking on the relationship between applications of mathematics and the teaching…

The computer has become an indispensable tool for teachers. Presently, many teachers are making efforts to master needed computer application skills. This study first focused on the differences between novice and experienced users to identify possible task-oriented factors that might help novice users overcome the learning curve. Errors frequently…

Eleven learning-handicapped students, ages 8-13, generated text at microcomputers both alone and as members of dyads. Examination of mechanical errors revealed a lower error rate in the dyad condition compared to working alone. The relationship between error monitoring and the social interaction needed for collaboration is discussed. (Author/JDD)

A study investigated the roles of phonological encoding and visual processes in word recognition in American learners of Arabic as a foreign language. Subjects were 36 individuals with proficiency ranging from beginning to native. Two experiments in word recognition were conducted, one at word and one at sentence level. At each level, the word…
