In education and the social sciences, problems of interest to researchers and users of research often involve variables that do not meet the assumptions of regression in the area of an equal interval scale relative to a zero point. Various coding schemes exist that allow the use of regression while still answering the researcher's questions of…

Students who learn mathematics with CAS calculators are likely to develop new practices for doing and recording mathematics. Students discussed in this paper were able to use CAS calculators in examinations, making their own decisions about what to document as written records for solutions to problems. A comparison of some features of written…

The Microsoft Certification Program (MCP) includes many new computer-based item types, based on complex cases involving the Windows 2000 (registered) operating system. This Innovative Item Technology (IIT) has presented challenges beyond traditional psychometric considerations such as capturing and storing the relevant response data from…

This codebook contains the layout and descriptive information for survey and sampling variables for the public-use version of the 1993-94 Schools and Staffing Survey (SASS). Information in this volume allows the user to access the data file. This volume opens with a discussion of created variables and some user notes. Four appendixes contain the…

The usefulness of the curriculum vita (CV) as a data source for examining the career paths of scientists and engineers was studied. CVs were obtained in response to an e-mail message sent to researchers working in the area of biotechnology who were funded by the National Science Foundation (55 responses) or listed as authors (industry only) in the…

A survey of 26 Rorschach experts and 19 students of Rorschach use was conducted to help students using the Exner Comprehensive System determine whether to code movement for nouns with definitions that include movement. Experts and students did not reach agreement, but a literature review suggests such nouns should often be coded as movement. (SLD)

Investigates the cognitive and linguistic demands of learning algebra and explores students' understanding of algebraic notation. Findings indicate specific origins of misinterpretation that include intuitive assumptions and pragmatic reasoning about a new notation, analogies with familiar symbol systems, interference from new learning in…

A. S. Kaufman (1994) recommended that clinicians substitute Symbol Search, a new subtest, for the Coding subtest when calculating Performance and Full Scale IQs on the Wechsler Intelligence Scale for Children-III. Tables are provided for accurate derivation of IQs, percentile ranks, and confidence intervals when this substitution is made. (SLD)

Developed an empirical strategy for transforming ordinal counts and percentages to interval scale measures by recoding them as ordered categories and estimating Rasch model scale parameters. Demonstrated the strategy for a neighborhood construct defined by 8 characteristics of 77 Chicago, Illinois, neighborhoods. (SLD)

Examination of the coding of interview data in studies of the aspirations of British Muslim girls and transition to math teaching compared manual and electronic methods. Choice of methods depended on the size of the project, funds, time, and research expertise. (SK)

Questions asked by elementary students in response to narrative texts were coded by university and elementary teachers. The coding schedule was consistently applied. The community of inquiry approach helped develop students' critical analysis skills. Careful selection of texts was recommended for successful use of the approach. (Contains 23…

Provides critical analysis of Edwards (1992) presentation of a set of examples from the Child Language Data Exchange System as prototypes of bad transcription practice. The analysis argues that Edward's approach causes the development of an overly rigid set of principles that could stop progress in the analysis of spontaneous language samples.…

Describes a method for compressing tomographic images obtained using Positron Emission Tomography (PET) and Magnetic Resonance (MR) by applying transform compression using all available dimensions. This takes maximum advantage of redundancy of the data, allowing significant increases in compression efficiency and performance. (13 references) (KRN)

Discusses a flexible, high performance subband coding system. Residual vector quantization is discussed as a basis for coding subbands, and subband decomposition and bit allocation issues are covered. Experimental results showing the quality achievable at low bit rates are presented. (13 references) (KRN)

The study examined speech production abilities of 14 poor readers and 14 age-matched (second and third graders) nondisabled readers. Subjects were taught to produce four novel, multisyllabic nonsense words. Analysis indicated that encoding limitations rather than speech production limitations were primarily responsible for disabled readers' longer…
