Discusses ways in which datalogging equipment can enable titration curves to be measured accurately and how computing power can be used to predict the shape of curves. Highlights include sources of error, use of spreadsheets to generate titration curves, titration of a weak acid with a strong alkali, dibasic acids, weak acid and weak base, and…

Describes the use of a spreadsheet in running a hands-on prey/predator simulation that enables students to see the effect of selection pressure on one allele in a gene pool. Discusses setting up and running the simulation, class discussion issues, exploring assumptions, and extensions. (JRH)

Demonstrates the application of spreadsheet analysis in solving equations beyond quadratics. Considers the costs of interest, gasoline, and maintenance in deciding how long it pays to keep a car. (MKR)

Discusses children's use of spreadsheets and the access that this gives to the instantaneous production of a variety of graphs. (10 references) (MKR)

Describes an activity that demonstrates the use of the spreadsheet as a tool to handle lower level mathematics (computations), freeing students and teacher to focus on the higher level concepts in the problems. (SR)

Discusses shareware and public domain software for MS-DOS systems that are available through bulletin board systems (BBS). Problems with computer viruses are discussed; shareware available for communications, database and file management, spreadsheets, word processing, and menuing software is described; and source information for software is…

Examines skill contexts for Application of Number, one of six UK-defined Key Skills similar to the Australian-defined Key Competencies, as part of a broader research objective of identifying a range of employer-defined skill profiles that characterize workplace performance. Indicates that spreadsheets are assuming a pre-eminent position and…

Describes research using a pedagogic strategy developed during an exploratory work called Active Graphing in which access to spreadsheets allows graphs to be used as analytic tools within practical experiments. Identifies aspects of student interaction with the experiment itself, the data collected and the graphs, and traces the emergence of…

Explores simple equations such as the exponential decay function, a terminal velocity situation, and the more complex situations of the simple harmonic oscillator and damped oscillations. (Author/CCM)

Using Microsoft Excel, several interactive, computerized learning modules are developed to demonstrate the Central Limit Theorem. These modules are used in the classroom to enhance the comprehension of this theorem. The Central Limit Theorem is a very important theorem in statistics, and yet because it is not intuitively obvious, statistics…

To integrate technology into mathematics teaching and learning effectively, teachers could create a technology-based learning environment that provides students with opportunities to experience the process of mathematical investigation. These opportunities range from exploring using mathematical ideas to making and testing conjectures, as well as…

NCTM's "Technology Principle" challenges mathematics teachers to rethink the mathematics they teach, investigate technological tools for learning mathematics, and consider how they can support students in learning mathematics with technology as a tool. In concert with the NCTM's emphasis on using technology as a tool in mathematics, ISTE's NETS…

Spreadsheets to explore regression with an algebra 2 class in a medium-sized rural high school are presented. The use of spreadsheets can help students develop sophisticated understanding of mathematical models and use them to describe real-world phenomena.

Applying the budget line/indifference curve apparatus to policy issues reveals important and sometimes counterintuitive policy implications. Also, it provides practice in using the apparatus. The author applies these tools to subsidies. The analysis follows textbook treatments but is extended at some points. In particular, the present analysis…

In "Beyond Pascals Triangle" the author demonstrates ways of using "Pascallike" triangles to expand polynomials raised to powers in a fairly quick and easy fashion. The recursive method could easily be implemented within a spreadsheet, or simply by using paper and pencil. An explanation of why the method works follows the several examples that are…
