Vertical scales are widely used in educational assessment as a basis for considering grade-to-grade changes in student performance. Typically, the underlying construct is assumed to be essentially unidimensional; however, if there is a change in the measured construct across grades, this assumption may be untenable. Developing a multidimensional…

We conducted a 14-week experimental study of 2 versions of a relatively comprehensive RC intervention that involved 50 classroom teachers, 15 tutors, and 116 children drawn in equal proportions from grades 3 and 5 in 13 schools in a large urban school district. Students were randomly assigned in equal numbers to the two tutoring conditions and a…

We conducted a 14-week experimental study of 2 versions of a relatively comprehensive RC intervention that involved 50 classroom teachers, 15 tutors, and 120 children drawn in equal proportions from grades 3 and 5 in 13 schools in a large urban school district. Students were randomly assigned in equal numbers to the 2 tutoring conditions and a…

"Research in the Teaching of English" (RTE) is the flagship research journal of the National Council of Teachers of English (NCTE) in the United States. It is a broad-based, multidisciplinary journal composed of original research articles and short scholarly essays on a wide range of topics significant to those concerned with the…

This study aims to investigate a construct of reading comprehension of geometry proof (RCGP). The research aims to investigate (a) the facets composing RCGP, and (b) the structure of these facets. Firstly, we conceptualize this construct with relevant literature and on the basis of the discrimination between the logical and the epistemic meanings…

The purpose of this study was to examine the technical adequacy of a computer-based assessment instrument which is based on hierarchical models of text comprehension for monitoring student reading progress following the Curriculum-Based Measurement (CBM) approach. At intervals of two weeks, 120 third-grade students finished eight CBM tests. To…

This article reports two studies to illustrate methodologies for conducting a conditional covariance-based nonparametric dimensionality assessment using data from two forms of the Test of English as a Foreign Language (TOEFL). Study 1 illustrates how to assess overall dimensionality of the TOEFL including all three subtests. Study 2 is aimed at…

Exploratory multidimensional scaling and confirmatory nonparametric procedures were used to represent data from similarity rating and sorting tasks on nine animal names administered prior to and following the reading of two stories using those names as main characters. Changes in structure were related to authors' intent. (Author/JKS)

Multidimensional scaling was used to study the comprehension of prose. Undergraduates rated the similarity of twenty nouns before and after reading passages containing those nouns. Results indicated that the scaling analysis provided an effective valid indicator of prose representation. (Author/JKS)

This study investigated (1) relationships between reading comprehension, IQ, and equivalence range (ER) and (2) categorizing styles through multidimensional scaling and varimax rotation analysis. One hundred and six male and 97 female sixth-graders comprised three reading groups according to Metropolitan Achievement Test, Reading subtest, and Otis…

Indicates that membership in pausing and skimming clusters appears to relate to text comprehension, grade level, and rated academic ability, but that these relationships are not all simple or direct. Finds that the cluster-analytic approach provides a useful empirical adjunct to current theoretical perspectives on text analysis and reading…

The reliability, sensitivity, and criterion-related validity of concept comparison (CC) ratings and computer-derived multidimensional scaling (MDS) maps were studied as ways of assessing reading comprehension. Fifteen experts (2 district coordinators and 13 reading specialists/special education teachers) were included in this study. Reliability…
