Nine types of errors occurring in the process of synthesizing research are described, with examples from a recent synthesis of research on teacher professional growth. Types of errors include excluding relevant literature, wrongly reporting details such as sample size, erroneously attributing findings to studies, and stating unwarranted…

This overview of the role of error and tolerance for error in measurement asserts that the generic precision associated with a measurement procedure is defined as the root mean square error, or standard error, in some relevant population. This view of precision is explored in several applications of measurement. (SLD)

Considers the existence of halo effects in individuals' evaluations of target communicators across different dimensions. Notes that halo effects result from raters' inability to discriminate among conceptually distinct and theoretically independent aspects of a target's behavior. Discusses current conceptions of halo error and suggests several…

Alerts communication researchers to potential errors stemming from the use of SPSS (Statistical Package for the Social Sciences) to obtain estimates of eta squared in analysis of variance (ANOVA). Strives to clarify issues concerning the development and appropriate use of eta squared and partial eta squared in ANOVA. Discusses the reporting of…

An experimental study was conducted of 2 different approaches to the correction of consistent subtraction errors in 6 students aged 12-13. Tentative findings demonstrate the superiority of the old way/new way method compared to use of Multibase Arithmetic Blocks and place value charts. (JDD)

Environmentally contaminated speech errors (irrelevant words or phrases derived from the speaker's environment and erroneously incorporated into speech) are hypothesized to occur at a high level of speech processing, but with a relatively late insertion point. The data indicate that speech production processes are not independent of other…

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)
