This paper presents teaching strategies and examples developed for a two-semester sequence in quantitative problem solving, specifically outlining a non-calculus derivation of linear regression formulas supported by the graphical display of the TI-83 calculator to visualize the minimization of the sum-squared vertical distances. The paper…

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…

Reports on a survey of Missouri teachers' knowledge about, practices with, and attitudes toward the use of calculators in mathematics instruction. Teachers were unaware of many uses for calculators and were unfamiliar with research on their use. (IRT)

Discusses the overuse of calculators in mathematics classrooms. Argues that the sole purpose of teaching mathematics is for thinking and discipline and these goals cannot be obtained when using calculators. (ASK)

Describes a calculator exercise that can help students develop a better visual and numeric feel for Newton's method. (KHR)

Explores the extent and nature of students' calculator usage as determined from examination scripts in the Western Australian Calculus Tertiary Entrance Examination. Discusses errors made and understanding called upon for seven questions. Discusses instruction and assessment of skills associated with graphical interpretation. (Author/KHR)

Presents reasons for students' use of calculators in math class and techniques for encouraging their optimal use. Many educators suggest that calculators free students from concentration on computation and enable them to concentrate on problem solving. The article includes product information. (SM)

Presents a study in which three classes of grade 10 students worked with graphics calculators throughout, five classes used them for approximately two months, and four classes did not use them at all. Posttest results showed that students who had worked with graphics calculators tended to attempt more problems and obtain higher test scores than…

Suggests a model for the learning and reinforcing of algebraic manipulative skills through the intensive use of group work using computer algebra systems (CAS). Suggests a model for assessing students through group work, for using the TI-92 as a self-assessment tool, and in cross-curricular activities. (Author/ASK)

For over a decade mathematics instructors have been using graphing calculators in courses ranging from developmental mathematics (Beginning and Intermediate Algebra) to Calculus and Statistics. One of the key functions that make them so powerful in the teaching and learning process is their ability to find curves of best fit. Instructors may use…

Two technology guidelines are contributed by Robin Rider of East Carolina University based on the TI-Interactive software she had introduced. The two guidelines to use for this software consist firstly of data gathering with a Calculator-Based Laboratory (CBL) and Calculator-Based Ranger (CBR) without a graphing calculator, and secondly the…

In this article, the authors describe how to use a TI-73/83/84 graphing calculator and Vernier's LabPro/CBL2 probe system to take pH readings. This is not an endorsement of these products, but simply the authors' attempt to give readers an idea of what is involved in using this technology in the classroom. This activity can be accomplished using a…

This volume contains the proceedings of the International Conference on Technology in Mathematics Education (TIME 2000). It includes papers, posters, and short oral reports. Research papers include: (1) "Implications of the Shift from Isolated Expensive Technology to Connected, Inexpensive, Ubiquitous and Diverse Technologies" (Jim…

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…

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…
