In educational assessments two types of missing responses can be discerned: items can be "not reached" or "skipped". Both types of omissions may be related to the test taker's proficiency, resulting in non-ignorable missingness. This paper proposes to model not reached and skipped items as part of the response process, using…

Comparability studies between CBT and PPT studied if there were score differences between these two versions. However, there were no consistent results across studies and time. The purpose of this study is to summarize the testing mode effects for K-12 mathematics tests by conducting a meta-analysis. 103 effect sizes of 32 studies were collected…

Over the few years, computer based language testing has become prevailing worldwide. The number of institutions the use computers as the main means of delivery has increased dramatically. Many students face each day tests for well-known high-stakes decisions which imply the knowledge and ability to use technology to provide evidence of language…

This paper briefly discusses four measurement challenges of data science or "big data" in educational assessments that are enabled by technology: 1. Dealing with change over time via time-based data. 2. How a digital performance space's relationships interact with learner actions, communications and products. 3. How layers of…

This document is from a presentation at the 2015 annual conference of the Science Teachers Association of Texas (STAT). The two sessions (each listed as feature sessions at the state conference) examined classroom strategies the presenter used in his chemistry classes to maximize Texas end-of-course chemistry test scores for his special population…

The vertical scales of large-scale achievement tests created by using item response theory (IRT) models are mostly based on cluster (or correlated) educational data in which students usually are clustered in certain groups or settings (classrooms or schools). While such application directly violated assumption of independent sample of person in…

This paper was delivered as a response to a presentation by Jan Kronberg MLC, Chair of the Education and Training Committee, Parliament of Victoria that published a report of the "Inquiry into the Extent, Benefits and Potential of Music Education in Victorian Schools." Her presentation and this response were part of a forum conducted by…

In this article we are presenting the results of the research "The Connection between the Results in the National Assessment of Knowledge and the Pupils' Socio-cultural Environment, Instruction and Homework," taking place at the National Education Institute, Slovenia, in the years 2008/2009. In the introduction we are writing the…

Competitions are used by many teachers at the grass roots level to develop the talents of their gifted students. Each year the top Math, Chemistry, and Physics Olympiad students are identified and assembled into national teams that compete against teams from around the world. This article summarizes findings from the American Olympiad study. Our…

The concept of dynamic vertical scaling (DVS) from longitudinal point of view has been proposed as comparing to traditional vertical scaling or static vertical scaling (SVS) from cross-sectional perspective. The effects of differences between DVS and SVS on large-scale student achievements have been investigated. The potential application of DVS…

The purpose of this study was to determine the relationship between mathematics and reading/language arts Comprehensive Assessment Program (TCAP) scores at a selected elementary school. The sample consisted of 12 randomly selected males in a third grade classroom. Data were collected for this study using the overall reading/language arts subtest…

The purpose of this paper is to identify and discuss some of the problems presented by the use of computerized adaptive testing (CAT) in an instructional programs environment versus large scale testing applications, and to describe an actual implementation of CAT in an instructional programs setting. This particular application is in the…

This paper examines long-range problems caused by test-controlled schooling. It looks at the demands of both curricular and accountability uses of tests from the point of view of the urban school district's testing office. On the basis of interviews with 12 New Orleans teachers and the experiences of the authors in working in two large city…

A new testing strategy that provides protection against the problem of having examinees in adaptive testing choose difficulty levels that are not matched to their proficiency levels was introduced and evaluated. The method, termed restricted self-adapted testing (RSAT), still provides examinees with a degree of control over the difficulty levels…

This is a descriptive study of the activities, statistics, and decisions made regarding the re-testing of six inner-city elementary schools, based on results of a norm-referenced achievement test given in the Cincinnati Public School district in April, 1985. Three statistical operations were performed on test data from the Design for School…
