Describes a method for inducing a theoretical model of a series of events that occur in an ongoing process. A data analysis method that transforms narrative data into event histories is explained, a spreadsheet display that compares event histories is described, and future research is suggested.

Discusses a method that uses spreadsheets to calculate the exact distribution of the sum of two or more discrete random variables with arbitrary distributions. Demonstrates how this method can be used to investigate several problems that would be found interesting at the elementary level. (Author/ASK)

Explores a birthday-related problem that asks about the probability of having people with the same birthday in a room. Utilizes spreadsheets to work on the problem and discusses related teaching issues. Contains 20 references. (ASK)

Explores how students interpret algebraic notation and what teachers can do to support appropriate interpretations. Presents two research-based strategies and concludes that in the face of reform and technological advances, finding a definition for symbol sense takes on added significance. Contains 22 references. (ASK)

Describes the use of spreadsheets as an alternative means of teaching complex mathematical concepts through simulation using the topic of the statistical power of tests as an example. Through the simulation it is possible for the learner to explore the design factors that influence power. Also provides a simple way of calculating power as a…

Highlights work done in a variety of preservice and in-service mathematics teacher education courses to help teachers use commonly available spreadsheets as an interactive exploratory learning tool. Discuses several examples of teachers' subsequent use of spreadsheets in their own teaching. (Contains 11 references.) (Author/ASK)

Designs a set of spreadsheet-supported activities to examine how preservice and inservice teachers behave in an exploratory computer setting, thus providing clues capable of informing the design of other learning opportunities using this technological tool. Describes the content of the activities devised and some of the strategies used by teachers…

The use of group work, in which three or more students jointly produce a piece of work for summative assessment, is an established aspect of teaching and learning in higher education. Opinions vary however about whether their marks should vary according to the respective contributions they made to the work. This paper is based on the assumption…

We describe a simple undergraduate exercise involving the titration of a weak acid by a strong base using a pH meter and a micropipette. Students then use their data and carry out graphical analyses with a spreadsheet. The analyses involve using mathematical concepts such as first-derivative and semi-log plots and provide an opportunity for…

In science, inquiry is used as students explore important and interesting questions concerning the world around them. In mathematics, one contemporary inquiry approach is to create models that describe real phenomena. Creating mathematical models using spreadsheets can help students learn at deep levels in both science and mathematics, and give…

If larger and larger samples are successively drawn from a population and a running average calculated after each sample has been drawn, the sequence of averages will converge to the mean, [mu], of the population. This remarkable fact, known as the law of large numbers, holds true if samples are drawn from a population of discrete or continuous…

Todd Lee and colleagues share some of the common technology "pranks" and peculiarities from the three most common technology tools used in our classrooms: Microsoft Excel, graphing calculators, and The Geometer's Sketchpad. The "Surfing Note" includes a link to a collection of funny math cartoons from the Carolina Biological Supply Company.

Spreadsheets can be a powerful tool when it comes to teaching physics. From data analysis and graphing to animated simulations, Excel[R] is a very versatile program for the educator and learner alike. This paper describes and supports another use for Excel through Reflective Formative Assessment Spreadsheets (RFAS). To illustrate the use of RFAS,…

The basic properties of extensive air showers of particles produced in the interaction of a high-energy primary cosmic ray in the Earth's atmosphere are discussed in the context of educational cosmic ray projects involving undergraduate students and high-school teams. Simulation results produced by an air shower development code were made…

This case study investigated the impact of a spreadsheet (EXCEL) exploration on the understanding of statistical graphs among twenty Singapore secondary school students of average ability. Four EXCEL templates were constructed to allow students to explore four aspects of statistical graphs: zero in scale, effect of different scales, size…
