The precision of measurements in today's society is discussed and is related to the range of uncertainty or variation of measurement. Numerous examples provide insight into the margin of error in any measurement. The issue of uncertainty is particularly applicable to levels of toxic chemicals in the environment. (SA)

The article outlines specific procedures for analyzing student errors and using the information gained as a tool for making appropriate assessment and instructional decisions. (DLS)

It is asserted that many errors in a foreign language result not merely from inaccurately learned grammatical items or structures but also from failure to understand the meaning distinctions indicated in the grammar of the new language. Implications for language teaching are discussed. (Author/RM)

This article discusses the relationship in language instruction between the verbo-tonal system of phonetic correction and a structuro-global audio-visual method which takes the communication aspects of language learning into account. (Text is in French.) (CLK)

Conclusions reached by recent studies of errors of students learning a foreign or second language give weight to the argument that an error analysis hypothesis could be used as a criterion for preparation of instructional materials. Error analysis reveals the learning strategies and processes in language education. (CHK)

Interviews conducted with each of 35 sixth graders who made errors on the Metropolitan Achievement Test showed little evidence that poor reading abilities affected children's success on word problems. (DT)

Identifies three types of translation blunders found in international business communication: those due to carelessness, those due to words having multiple meanings, and those due to idioms. A number of mistakes from actual advertising mistranslations are included as examples. (Author/CK)

Examined relations between algebraic word-problem attributes and students' strategies, errors, and problem difficulty. Found that constructed responses capture strategy formulation and high-level planning--as do traditional measures of quantitative reasoning--but are more sensitive to individual problem characteristics and procedural errors that…

Two experiments examined the communicative bases of preschoolers' object appearance-reality (AR) errors. Found that AR performance correlated positively with performance on a control test with the same discourse structure but nondeceptive stimuli, and on a naming test. Overall findings indicated that the discourse structure of AR tests elicits a…

Presents an alternative definition of negative evidence, based on the idea that the unique discourse structure created in the juxtaposition of child error and adult correct form can reveal the child in contrast or conflict between the two forms. Findings reveal that children reproduced the correct irregular model more often and persisted with…

From an interlanguage perspective, argues that many perplexing errors in second language writing are the result of the interaction between developing linguistic competence and basic principles of ordering information in texts that learners already know. Shows how this interaction results in errors at the sentence level. These insights are applied…

This study compared the levels and types of errors found in an existing card catalog and a newly created online catalog. It was found that the online catalog was more accurate and presented fewer problems for users. The implications for retrospective conversion and nonconverted records are discussed. (eight references) (CLB)

False positive and false negative error rates were studied for competency testing when failing examinees are permitted to retake the test. Formulas are provided for the beta-binomial and Rasch models. Estimates based on these models are compared for six data sets from the South Carolina Basic Skills Assessment Program. (SLD)

Evaluation of the speech of five Dutch-speaking adolescent girls with Down's syndrome found that speech errors tended to be identical to the error patterns in young normal children supporting the view that misarticulations in Down's syndrome subjects are mainly the result of a delay in speech development.

Difficulties experienced by algebra students are listed, with comments on what can be done and some implications for teaching. (MNS)
