Previous research on calculator use in standardized assessments of quantitative ability focused on the effect of calculator availability on item difficulty and on whether test developers can predict these effects. With the introduction of an on-screen calculator on the Quantitative Reasoning measure of the "GRE"® revised General Test, it…

The goal of this study was to determine whether adult students incarcerated at a large correctional facility in New England use the provided scientific calculator appropriately when taking the Official GED Practice Test in mathematics. 13 students were interviewed after taking a practice test and asked for their strategy for solving each problem.…

The purpose of this study was to use differential item functioning (DIF) and latent mixture model analyses to explore factors that explain performance differences on a large-scale mathematics assessment between examinees allowed to use a calculator or who were afforded item presentation accommodations versus those who did not receive the same…

Handheld calculators have been used on the job for more than 30 years, yet the degree to which these devices can affect performance on employment tests of mathematical ability has not been thoroughly examined. This study used a within-subjects research design (N = 167) to investigate the effects of calculator use on test score reliability, test…

In order to estimate the likely effects on item difficulty when a calculator becomes available on the quantitative section of the Graduate Record Examinations® (GRE®-Q), 168 items (in six 28-item forms) were administered either with or without access to an on-screen four-function calculator. The forms were administered as a special research…

Inquires into assessment items classified as "extended pieces of work" in applicable mathematics in Western Australia. Identifies opportunities for graphics calculator use in extended pieces implemented in schools. Concludes that availability of the technology has widened the scope of approaches used in extended pieces of work in…

Discussed are experiences in using the calculator to assess mathematical understanding on the Missouri Mastery and Achievement Tests (MMAT). Data from a calculator group and a no-calculator group at the eighth- and tenth-grade levels are reported. Several items showed differences between groups. (YP)

This study investigated the relationship between instructional use of handheld graphing calculators and student achievement in Algebra 1. Three end-of-course test forms were administered (without calculators) using matrix sampling to 458 high-school students in two suburban school districts in Oregon and Kansas. Test questions on two forms were…

Advanced Placement Calculus examinations were administered to nearly 7,000 students in order to determine the impact of calculator use. Both experimental examinations had two sections. Section I items were designed so that a calculator was not needed, but approximately half of the students were permitted to use calculators. Section II items…

The use of scientific calculators on standardized mathematics tests is becoming more common, and how their use affects the standardized testing process continues to be a topic of study. This study extends previous work by examining test item characteristics and equity issues, asking whether items designed to be "calculator neutral"…

Four mathematics test-item types that may perform differently when calculators are used were assessed using data from 160 high school students attending a summer enrichment program. The effects of testing with and without calculators on testing time, test reliability, item difficulty, and item discrimination were also assessed. (TJH)

Studied effects of students' use of calculators with 2 experimental forms of a university mathematics test taken by 765 and 725 college students, respectively. Calculator effects are not found for overall scores but are seen for some individual items. Analysis at the item level makes the actual impact apparent. (SLD)

Half of a sample of 11,457 college-bound juniors used a calculator on Scholastic Aptitude Test mathematics questions, while half did not. Both genders and three ethnic groups benefited about equally from calculator use. Students who routinely used calculators were relatively advantaged, but effects on individual test items varied. (SLD)
