This exploratory study investigated the behaviors and content of onscreen calculator usage by a nationally representative sample of eighth-grade students who responded to items from the 2017 National Assessment of Educational Progress mathematics assessment. Meaningful features were generated from the process data to infer whether students…

In this study, the effect of using on-screen calculators on eighth grade students' performance on two TIMSS 2019 Problem Solving and Inquiry Tasks items considered as examples of technology-enhanced items administered on computers was examined. For this purpose, three logistic regression models were run where the dependent variables were giving a…

To help middle school students make better sense of decimals and fraction, the author and an eighth-grade math teacher worked on a 90-minute lesson that focused on representing repeating decimals as fractions. They embedded experimentations and explorations using technology and calculators to help promote students' intuitive and conceptual…

Stresses the value of graphing and computer algebra systems calculators when teaching about waves. Discusses how to input data into these calculators. Highlights the Texas Instruments' (TI) Web site at http://www.ti.com. (YDS)

This paper describes how 8th grade students are using CBR, a motion detector linked to a graphing calculator, as a way of generating mathematical ideas regarding the motions concepts that surround their action. Students were previously introduced to the calculators in the classroom and teaching experiments were then carried out afterwards with a…

The intent of this study is to determine whether or not teaching students how to use available calculators can improve their mathematics test scores. The study involved 89 seventh and eighth grade students. These students were randomly divided into three separate groups which included two experimental groups and the control group. The control…

This study used data from the Third International Mathematics and Science Study (TIMSS) to determine trends in calculator use among Population 2 (13-year-olds) students in Japan, the United States, and Portugal. While relatively high levels of calculator use were observed for the U.S. and Portugal, virtually no calculator use was found in the…

This study addressed: (1) what difference, if any, would calculators make on a typical mathematics assessment instrument; (2) what might occur if students were allowed to use, but were not furnished with, calculators for testing; and (3) what implications do answers to these questions have for future statewide assessment. Eighth-grade students…

The paper deals with the facts obtained from TIMSS 2003 (Trends in International Mathematics and Science Study). This international comparative study, which includes 47 participant countries worldwide, explores dependence between eighth grade students' achievement in the areas of mathematics, physics, chemistry, biology and geography, and basic…

Students in grades four and eight were given parallel forms of mathematics subtests of Iowa Tests of Basic Skills, once using calculators and once without. Performance with calculators was compared to performance on regular administration of subtests. In both grades, mean scores on problem solving and computation subtests were significantly higher…

This paper provides a brief understanding of the educational technology in the teaching and learning of mathematics to Form Two students (equivalent to the eighth-graders) in Malaysia. In particular, it attempts to understand the relationships between educational technology and mathematics achievement in both the urban and rural schools. The study…

The purpose of this study was to examine the relationships between the use of technology and student computation and geometry achievement. The study also examined possible relationships between achievement differences related to demographic and background characteristics of the students and the use of technology. The sample of 956 students in…

The National Science Foundation funded Calculators and Mathematics Project, Los Angeles (CAMP-LA) developed curriculum materials focused solely on the use of calculators. The project was developed in three stages. The first stage studied the mathematics curriculums from different states and identified topics that are not included but should be if…
