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.

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. (Author/DB)

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

Tests of (n=107) third through sixth graders' basic addition facts found that 34% of errors involved the addition of zero and 83% of the remaining errors involved at least one of the digits 7, 8, or 9 when the other addend was 4 or more. (20 references) (MKR)

Describes a study that was conducted to determine how error patterns and a clinical approach to assessing third grade students' mathematical knowledge interrelate to design a computer diagnostic system for subtraction. Error patterns are examined, and computer diagnostic systems and analytical testing are discussed. (34 references) (LRW)

Predictive validity of preadmissions measures may be understated because of correctable defects in freshman year and cumulative high school grade point averages (GPAs). A study used item response theory (IRT) to develop a more reliable measure of performance and test it using Stanford University data. Results showed increased predictability.…

A checklist is presented to identify common problems students exhibit in arithmetic. Alongside general areas of need, common mistakes are listed to help diagnose error patterns for targeting specific skills and designing effective intervention. General areas include readiness, problem solving, whole-number computations, fraction computations, and…

Spelling errors made by children on initial consonant clusters of words were studied in 5 experiments with 130 first graders and 20 kindergartners. Young spellers have frequent problems with initial consonant clusters. Results suggest that difficulties in phonemic awareness lead to corresponding spelling difficulties. (SLD)

This response to Fey (EC 604 058) discusses the use of the term "phonological" to describe disordered speech patterns and suggests that phonological disorders include both phonetic and phonemic error types. Describing errors as either phonetic or phonemic is seen to lead to differential treatment procedures. (Author/DB)

Twelve secondary students with learning disabilities read aloud from a text after previewing the passage under one of three conditions. Results showed significant decreases in error rates under slow-rate listening previewing and silent previewing and showed that slow-rate listening previewing resulted in fewer errors per minute than did fast-rate…

To test the cross-cultural generality of relational-models theory, 4 studies with 70 adults examined social errors of substitution of persons for Bengali, Korean, Chinese, and Vai (Liberia and Sierra Leone) subjects. In all four cultures, people tend to substitute someone with whom they have the same basic relationship. (SLD)

To investigate mistakes in the reporting of diagnostic efficiency statistics, all studies of the diagnostic performance of self-report scales in two psychological journals published between 1980 and 1991 were reviewed. Of 26 relevant studies, 9 had an error in calculation of diagnostic efficiency. Implications are discussed. (SLD)

Analyzes the metaphors and theories used by instructors to conceive of their work with students labeled as "basic writers." Posits alternative metaphors for these students. Discusses theoretical and pedagogical approaches to written "error." Argues for a redefinition of the "territory of basic writing" as…

This article describes an empirical investigation of the extent to which incorrect arithmetic algorithms persist over time. Results with 30 fourth-year and third-year English students over up to 3 months shed light on "bugs," or students' learning of incorrect concepts, and indicate that they are not very stable in children of this age.…
