This study reports on the development, validation, and reliability of a geometry disposition scale (GDS) to measure pre-service teachers' (PSTs') attitudes to geometry learning. PSTs from two Colleges of Education (CoEs) in Ghana volunteered to participate in the study (N = 153). A principal component analysis (PCA) extracted four factors: deep…

This descriptive research study examined 2013 NAEP 12th-grade mathematics scores by students' use of graphing calculators in math classes and the kind of calculator students used during NAEP assessment. NAEP Data Explorer analysis included two questions from Student Factors: How often do you use these different kinds of calculators in math class?…

This paper reports on the role of the graphing calculator (GC) in the learning of derivatives and instantaneous rate of change. In a longitudinal study, we administered task based interviews before and after the introduction of calculus. We analyzed students' use of the GC in these interviews. This paper reports on the case of one student, Andy,…

This paper reports an instrumental case study of the strategies employed by Year 11 students engaged in solving a functions population task. The task was implemented as part of a study of students studying functions in a Technology-Rich Teaching and Learning Environment (TRTLE). Student strategies related to the perception and enactment of…

The beliefs of preservice elementary-school teachers regarding the use of basic calculators and "Illuminations" activities were investigated. The goals of the study were to describe preservice teachers' beliefs, identify the sources of those beliefs, and determine which interventions successfully modify them. Participants included 210…

This study sought to gather empirical evidence of the effectiveness of calculus instruction like that used in the Calculus and Mathematica project by examining and comparing the effects of three different instructional approaches to calculus on students' (n=100) abilities to use and understand connections between numerical, graphical, and symbolic…

This paper discusses TI-89 and TI-92 graphing calculators as a tool for teaching mathematics. How this technology is likely to affect the teaching of mathematics and the role of technology in general is described. Discussion begins with a comparison of two areas, mathematics and moving/transportation, from a technological aspect, and focuses on…

The purpose of this study was to determine the effects of an implementation plan that would support middle school science teachers as they integrated a specific technological tool, Calculator-Based Laboratory (CBL) probeware. The final goal of the implementation process was pedagogical and curricula transformation by the participants. The…

This paper discusses different ways of using statistics more creatively. One method begins with two conflicting headlines from newspapers and analyzes them statistically by using a graphing calculator. Other activities using graphing calculators are also presented. (ASK)

This paper presents three activities on how to analyze rates of change in real-life situations using TI-83 calculators and computer-based laboratories. Activities include 24 hour temperature data, the temperature of a light bulb, and an M&M toss. Each section contains descriptions of equipment/materials, data collection, and data analysis. The…

This project description is designed to show how graphing calculators and calculator-based laboratories (CBL) can be used to explore topics in the physics of sound. The activities address topics such as sound waves, musical notes, and chords. Teaching notes, calculator instructions, and blackline masters are included. (MM)

This paper presents the features of graphic calculator technology that can be implemented in noncalculus-based educational statistics courses. The objectives are to: (1) present potential uses of the graphing calculator; (2) discuss current research concerning graphing calculator implementation in the classroom; and (3) illustrate current…

The relationship between college students' preferred mode of processing mathematical information--visual or nonvisual--and their performance in calculus classes with and without technology was investigated. Students elected one of three different versions of an introductory differential calculus course: using graphing calculators, using the…

The study analyzed gender attitudes of students in learning mathematics by using a calculator, in one of Botswana's Junior Secondary Schools. Students' attitudes were sought using a questionnaire and data was analyzed by both quantitative and qualitative methods. Attitude variables used were usefulness of calculators, enjoyment and anxiety in…

Analysis of student achievement data following the introduction of graphics calculators to tertiary entrance examinations in mathematics in Western Australia suggests the possibility of an equity problem between the sexes in their usage. While males out-performed females in a number of categories, the most conclusive evidence emerged in questions…
