Cui, Zhongmin; Kolen, Michael J. – Journal of Educational Measurement, 2009
This article considers two new smoothing methods in equipercentile equating, the cubic B-spline presmoothing method and the direct presmoothing method. Using a simulation study, these two methods are compared with established methods, the beta-4 method, the polynomial loglinear method, and the cubic spline postsmoothing method, under three sample…

Qualls-Payne, Audrey L. – Journal of Educational Measurement, 1992
Six methods for estimating the standard error of measurement (SEM) at specific score levels are compared by comparing score level SEM estimates from a single test administration to estimates from two test administrations, using Iowa Tests of Basic Skills data for 2,138 examinees. L. S. Feldt's method is preferred. (SLD)

Freeman, Donald J.; And Others – Journal of Educational Measurement, 1983
This investigation attempts to determine if the congruity in textbook-test content varies as a function of different styles of textbook use. Across all standardized tests, instructional validity of the five styles of textbook use was far lower for the management-by-objectives model than for any other styles. (Author/PN)

Baglin, Roger F. – Journal of Educational Measurement, 1986
Norm-referenced standardized achievement tests are designed for obtaining group scores which can vary widely, depending on not only the measure of central tendency but also the type of derived score employed. This situation is hypothesized to be the result of using inappropriate statistical procedures to develop publishers' scaled scores.…

Waltman, Kristie K. – Journal of Educational Measurement, 1997
A socially moderated link was established between statewide achievement results and the National Assessment of Educational Progress (NAEP) by using the same achievement level descriptions in an Iowa Test of Basic Skills standard-setting and an NAEP standard setting study. A statistically moderated link was established through an equipercentile…

Feldt, Leonard S. – Journal of Educational Measurement, 1973
This paper provides a guide to the minimum size of treatment groups, inferred from the relationships between pupil norms and norms for class averages of standardized achievement tests. (Editor)

Plake, Barbara S.; Hoover, H. D. – Journal of Educational Measurement, 1979
An experiment investigated the extent to which the results of out-of-level testing may be biased because the child given an out of level test may have had a significantly different curriculum than the children given in-level tests. Item analysis data suggested this was unlikely. (CTM)

Baglin, Roger F. – Journal of Educational Measurement, 1981
While major test publishers randomly select school districts for their national norming studies, a survey of "accepting" and "declining" districts supports the hypothesis that self-selection bias results in overrepresentation of districts which already use a specific publisher's tests or instructional materials.

Cummings, Oliver W. – Journal of Educational Measurement, 1982
The stability of subskill scores on the Reading Comprehension Test of the Iowa Tests of Basic Skills was studied. It was concluded that the subskills are of limited use in diagnosing specific strengths or weaknesses in a student's reading comprehension skill development. (Author/GK)

Bliss, Leonard B. – Journal of Educational Measurement, 1980
A mathematics achievement test with instructions to avoid guessing wildly was given to 168 elementary school pupils who were later asked to complete all the questions using a differently colored pencil. Results showed examinees, particularly the more able students, tend to omit too many items. (CTM)

Iwanicki, Edward F. – Journal of Educational Measurement, 1980
Five new test batteries are reviewed: California Achievement Tests, Iowa Tests of Basic Skills, Metropolitan Achievement Tests, SRA Achievement Series, and Sequential Tests of Educational Progress. The review covers six basic areas: test administration, norming, test scores, reporting and interpretation, aptitude test considerations, and general…

Loyd, Brenda H.; Hoover, H. D. – Journal of Educational Measurement, 1980
Three levels of a mathematics computation test were equated using the Rasch model. Sixth, seventh, and eighth graders were administered different levels of the test. Lack of consistency among equatings suggested that the Rasch model did not produce a satisfactory vertical equating of this computation test. (Author/RD)
