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)

An articulation screening procedure that considered the phonological content of the child's error was compared to a procedure that treated all errors as equally important with 333 preschool children. Predicting eventual therapy placement was more accurate when only selected errors were used. (Author/DB)

Two studies that avoided methodological problems associated with inconclusive previous reports found that 6-year-olds had less reliable feeling-of-knowing (FOK) judgments but greater FOK accuracy than did 10- or 18-year-olds. Moreover, 18- and 70-year- olds had equally reliable FOK judgments and equivalent FOK accuracy. (RH)

An approach to teaching factors and terms is offered that builds directly on students' knowledge of arithmetic. Errors arising from factor and term confusions are noted, followed by the pedagogical strategy of exploration, invention, and discovery. (MNS)

Presents a conceptual framework and notation for learner modelling in intelligent tutoring systems based on the computational distinction between behavior, behavioral knowledge, and conceptual knowledge and between the system, the learner, and the system's representation of the learner. Approaches to learner modelling based on a review of the…

Spontaneous utterances from 3 conversational contexts were generated by 3 groups of 10 children, including children with specific language impairments (SLI), and analyzed for accuracy of pronoun usage. Results indicated that children with SLI exhibited more total errors than chronological peers but not more than their language level peers. A…

First graders listened to the pronunciation of single syllable nonsense words and were asked to spell the words. Results showed that, for nonsense words of the form consonant-vowel-consonant-consonant, in which the consonant following the vowel was a nasal or a liquid, children often omitted the second consonant in their spelling. (BC)

Found dissociations between regular and irregular inflectional processes in the formation of English past tenses, German noun plurals, and German participles. Children's inflectional errors include using regular patterns for irregular forms. Some linguistic processes, such as forming compound words, are sensitive to the distinction between regular…

This response to Fey (EC 604 058) presents arguments and examples in support of using concepts of phonological processes and constructs in assessing and treating phonological disorders in children. The paper disagrees with Fey's contention that using the term "process" for "rule" leads to confusion. (Author/DB)

An experiment with 67 Australian junior high school students demonstrates that presentation of goal-free 2-move mathematics problems, reducing the use of means-ends analysis, prevents the stage effect (increase in errors at the subgoal stage) from occurring. Implications for enhancing learning are discussed. (SLD)

Discusses recent advances in cognitive theory and the design of computer-based instruction and suggests implications for the design of authoring tools and tutoring system shells. Highlights include the design of courseware; advanced organizers; knowledge representation; design evaluation; models of knowledge; models of errors; and models of…

Investigates the written syntax of 81 college-able individuals demonstrating a specific learning disability. Supports a control impairment hypothesis, predicting that sentence production errors will be of the same kind as found in the language of writers demonstrating no handicapping conditions. Investigates the correlation of specific cognitive…

Examines whether dual-route models of spelling account for the misspellings of Spanish children of different educational levels. Finds that second graders relied heavily on phonological mediation, whereas eighth graders seemed to use a lexical strategy, and fourth-grade children showed an intermediate pattern. Finds support for dual-route spelling…

Investigates whether intermediate Turkish-speaking and English-speaking learners of Spanish know which unaccusative verbs alternate in transitivity and which ones do not, and whether they find causative errors natural with intransitive verbs. Results confirm similar findings to those reported in English interlanguage and first-language acquisition…

Errant mathematical views are widely found among teachers, their students, and authors of applied mathematics texts. Suggests classroom experimentation, both to confirm the occurrence of these errors, and to apply the appropriate corrective teaching. (Author/ASK)
