This paper provides new evidence on the effect of computerized individualized practice and instruction on language skills, more specifically on spelling. An individually randomized experiment among 7th grade students in the Netherlands is developed to study the effect of an adaptive digital homework tool on spelling performance. Using an…

Our spelling training software recodes words into multisensory representations comprising visual and auditory codes. These codes represent information about letters and syllables of a word. An enhanced version, developed for this study, contains an additional phonological code and an improved word selection controller relying on a phoneme-based…

We present an inference algorithm for perturbation models based on Poisson regression. The algorithm is designed to handle unclassified input with multiple errors described by independent mal-rules. This knowledge representation provides an intelligent tutoring system with local and global information about a student, such as error classification…

Working with three preschool children for nine weeks, a study examined effects on children's spelling when certain ways of employing various computer features are used within the context of a language experience approach. Each Monday and Friday the children were pretested and posttested on four spelling words dictated by the researcher. After…

Notes the existence of a collection of computer-readable files containing misspellings of English words, which is now available to researchers from the Oxford Text Archive in England. Describes the content of the collection. (FL)

Reviews the best currently available spelling software, including drill and practice, tutorial, game, and proofreading/word processing programs, and discusses criteria for spelling software selection. (MBR)

Based on research that views students' spelling ability as a result of "over-learning" words, this guide presents techniques and procedures for designing a spelling program integrated with reading and writing. Following an introduction, the first section presents answers to 12 commonly asked questions about spelling, and offers…
