This study applied the maximum expected information (MEI) and the maximum posterior-weighted information (MPI) approaches of computer adaptive testing item selection to the case of a test using polytomous items following the partial credit model. The MEI and MPI approaches are described. A simulation study compared the efficiency of ability…

An ability-based guessing model is formulated and applied to several data sets regarding educational tests in language and in mathematics. The formulation of the model is such that the probability of a correct guess does not only depend on the item but also on the ability of the individual, weighted with a general discrimination parameter. By so…

How do district policies, leadership, and support services influence the quality of teaching and learning in public schools? This article uses a rich longitudinal school-level database to estimate a model of student achievement and analyzes the residuals in the model to obtain estimates of the contributions of unobserved school and school district…

In a recent issue of the "AASA Journal of Scholarship and Practice," Hilling (2004) described procedures for obtaining a fair compensation process for principals, and the thrust of this work was on establishing internal consistency for salaries among administrators. This article addresses similar concerns, but differs in several important ways.…

The possible use of a calendar algorithm was assessed in DBC, an autistic "savant" of normal measured intelligence. Testing of all the dates in a year revealed a random distribution of errors. Re-testing DBC on the same dates one year later shows that his errors were not stable across time. Finally, DBC was able to answer "reversed" questions that…

A study examined the calculation of staff:student ratios (SSRs) in nursing and midwifery education in courses validated by the English National Board for Nursing, Midwifery and Health Visiting (ENB). Data were collected from questionnaires mailed to all 108 colleges of nursing and midwifery and higher education institutions offering ENB-validated…

This study investigated manifestations of collaborative work with pairs of kindergarten children during counting tasks designed to promote early number development. The data were collected by means of classroom observations, interviews with individual students, and teaching sessions with pairs of students. Ten students were paired to be compatible…

This paper summarizes an experiment conducted to examine the counting performance of 7- and 8-year-olds. Analysis of variance was computed on counting errors produced when enumerating a set of squares on a computer screen. The factors included in the analysis were age, gender, array size, error type, proximity, and error form. The primary…

This book provides regular classroom and special education teachers with alternative, individualized methods of teaching math computation skills. Learning activities are designed to appeal to auditory, visual, and kinesthetic learning modalities. Six mathematics topics addressed include modeling addition and subtraction, basic facts for addition…

In this instructional guide, a third-level, two-semester mathematics course specifically for the student who plans a career in a vocational field is presented. The course is designed to meet the needs of students with varying mathematical backgrounds and to teach the mathematical skills required by various technical areas. In this practical…

The relationships among types of errors observed during probability problem solving were studied. Subjects were 50 graduate students in an introductory probability and statistics course. Errors were classified as text comprehension, conceptual, procedural, and arithmetic. Canonical correlation analysis was conducted on the frequencies of specific…

This paper describes a study that examined parents' beliefs about children's number skill development. Twenty-seven parents of 4- and 5-year-olds were interviewed about number tasks that could be solved by children between the ages of 4 and 7 years. In addition, parents were asked a series of open-ended questions about how they would answer a…

Counting books offer children the time and the tools to develop the understanding needed to solve problems. Stimulated by these books, children may use mathematic language and talk about mathematics as they get involved with materials to move and manipulate, as they use supportive aids found in illustrations, and as they interact with materials to…

Describes the construction and use of the teacher developed nomograms as an aid in calculation for the less academic student, and in the teaching of mechanics, Boyles' law, and momentum. (GS)

The question addressed here is how to integrate computational tools, namely interactive general-purpose platforms, in the teaching of process units. Mathematica has been selected as a complementary tool to teach distillation processes, with the main objective of leading students to achieve a better understanding of the physical phenomena involved…
