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,…

In this paper, the relationships between students' beliefs about knowing and learning mathematics, and how they engage with calculators, are investigated. An online survey was conducted for 964 Singaporean and 176 Victorian senior secondary students. Students' "connected knowing-deep approach" conception of mathematics was found to be…

Since the 1999 fall semester, the TI-92 Plus or the TI-89 has been a compulsory purchase for new students entering one engineering school in Montreal, Canada (almost 1000 enrolments a year). The purpose of this paper is to share impressions of a campus-wide experience and to communicate solutions adopted to help students and faculty members in the…

Assumptions: In mathematics learning, one of the considerations in the graphing calculator (GC) use is to understand students' attitude toward calculators. Rationale: This presentation describes design of an assessment instrument of students' attitude toward graphing calculator. Objectives: A pilot study that assessed the effectiveness of the…

Drawing from experiences at Ohio State University (OSU) with remedial college students and with 12th grade students without elementary algebra skills, this paper outlines a numerical approach to algebra instruction using handheld calculators. Introductory material discusses problems with traditional approaches to math education and outlines some…

This paper explores questions about linear relationships through the use of pattern. Participants in the session generated and extended patterns and used calculators to investigate the relationships. Examples from current Texas Instruments (TI) books and U.S. textbook series, plus examples from proposed TI materials are shared. These activities…

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…

Discussed are the difficulties that entering college freshmen seem to have with mathematics, particularly with fractional forms. A success-oriented program is suggested in which all students are successful. To obtain this goal, a number of alternative routes are discussed such as presenting decimals before fractional forms and the use of the…

The study of linear functions is important as it provides students with their first experience of identifying and interpreting the relationship between two dependent variables. This paper, which builds on previous research, reports a study undertaken with 64 year 9 students from two Australian schools. Linear functions were introduced to these…

This paper presents some ideas on how to utilize TI-83 Plus calculators to perform division of one polynomial (the divided) by another polynomial (the divisor) and how that procedure might be incorporated into a college algebra lesson. Four ways to obtain the quotient and remainder when dividing a polynomial by a first-degree polynomial are…

Assumptions: Today, when technology has taken its place in almost all classrooms in schools and colleges across the country, there is a need to know how technology "influences the mathematics that is taught and enhances students' learning" (NCTM, 2000, p. 24). Rationale: This presentation describes qualitative study which purpose was to…

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…

In this report, we give a sociocultural account of the mediating functions handheld graphing calculators and social interaction play in students' mathematical understanding. We discuss the evolution of students' abilities to symbolize, model, and develop collective mathematical practices about polynomial inequalities in instrumented activity. In…
