The purpose of this mixed-methods study was to investigate the relationship between teachers' conceptions of mathematics and their use of intelligent tutoring systems for mathematics instruction. Intelligent tutoring systems are adaptive computer programs which administer mathematics instruction to students based on their cognitive state. A…

Findings from three years of a longitudinal randomized control trial involving a national U.S. sample of Algebra 1 teachers and students are reported. The study examines the effects of a connected classroom technology (CCT) professional development and classroom intervention on student achievement when compared to classroom instruction with…

Traditionally, mathematics has been taught using a very direct approach which the teacher explains the procedure to solve a problem and the students use pencil and paper to solve the problem. However, a variety of alternative approaches to mathematics have surfaced from a number of different directions. The purpose of this study was to examine the…

This study compares the respective achievement of students in an integrated algebra course taught with two different types of handhelds over a period of one year. The experimental group was taught with TI-Nspire[TM] handhelds and was compared to the control group taught with TI-84 Plus graphing calculators. The teachers of each group received…

Graphing calculators facilitate learners' ability to build cognitive links between mathematical representations by providing quick access to multiple representations. This exploratory study investigated the effects of technology-enhanced instruction on student achievement, perceptions of technology use during instruction, problem-solving success,…

This case study documents the struggles and successes encountered by a pre-calculus teacher while using Classroom Connectivity Technology (CCT) daily in her community college mathematics course. CCT refers to a wireless communication system that connects a teacher's computer with an individual student's handheld calculator and has been associated…

Calculators are a controversial, yet widely used tool in mathematics education for all students and especially for students with disabilities. However, little research has explored calculators and students with disabilities. This paper explored the influence of calculator type (four-function and graphing) on the mathematical performance of…

This article discusses the impact of a year long professional development on high school mathematics teachers' concerns regarding the implementation of graphing calculators in their classrooms. Teachers' concerns were assessed at the beginning and end of the yearlong professional development using the Concerns Based Adoption Model Stages of…

Graphing calculators and data collection technology was integrated in an undergraduate science methods classes for preservice elementary school teachers. The study investigated whether preservice teachers' knowledge and comfort with the use of graphing calculator technology and their perspectives in the use of graphing calculator technology were…

Compiles teachers' impressions of the barriers and/or incentives associated with the use of graphing calculators on classroom dynamics, curriculum and evaluation, training, support, and overall attitude. Concludes that teachers' perceptions of the advantages appeared to be instructionally related, whereas perceptions of the disadvantages appeared…

Focuses on changes in attitude toward mathematics and calculator use and changes in how general mathematics students naturalistically solve algebraic problems. Uses a survey to determine whether a student is rule-based. Concludes that the rule-based students used an equation to solve the algebraic word problem whereas the non-rule-based students…

Discusses the results of research which examines the perceptions of teachers as they initially engage in instruction using graphing calculators. Data were collected from 261 math and science teachers of grades 6-12. Participant views changed significantly overall in favor of viewing the graphing calculator as a thinking tool to enhance conceptual…

Reports on a research study that examined how some teachers used graphing calculators in their instruction of mathematics, and how their views of mathematics were manifested in the ways in which they chose to use this technology. Suggests that teachers used graphing technology as an extension to the way they always taught the unit. Contains 23…
