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…

The purpose of this study was to investigate the ways that teachers use connected classroom technology (CCT) in conjunction with the Texas Instruments Nspire calculator to potentially support achievement on Algebra problems that require translation between representations (i.e., symbolic to graphical). Four Algebra I classrooms that initially…

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,…

Manipulatives have been used in many mathematics classrooms across many age groups with the aim of helping students to understand abstract concepts through concrete, kinesthetic, and visual experiences. In this paper, after we provide a background for the use of physical and virtual manipulatives in teaching and learning of mathematics, we will…

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…

American students continue to struggle on measures of student achievement. This study employed Hierarchical Linear Modeling to estimate a two-level model and examine the influences of calculator use and teachers' instructional practices on student achievement in mathematics amongst first-grade students. The outcome variable was mathematics test…

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…

This paper was developed with the goal of enhancing the mathematical preparation of secondary school teachers in the technological paradigm. It shows how two-variable inequalities can be utilized as models for the construction of geometric objects using the software Graphing Calculator 3.5 (produced by Pacific Tech) as a relation grapher. An…

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…

This report summarizes findings on strategies chosen by students (n=38) when solving algebra problems related to various functions with the freedom to use a TI-83 graphing calculator, influences on student problem-solving strategy choices, student ability to approach algebra problems with use of multiple representations, and student beliefs on how…

This review analyzes, in the context of current mathematics education reform recommendations, literature related to graphics calculators, including results of some early studies assessing the impact of graphics calculators on the achievement and disposition of secondary and early college students.
