The development and application of a simulator designed with Excel spreadsheets to teach procedural skills in atomic absorption spectrometry and atomic emission spectrometry are proposed. For the development of the simulator, different analytical procedures were followed including analysis of pharmaceutical, forensic, and environmental samples.…

A spreadsheet-based exercise for students is described in which they are challenged to explain and reproduce the disparate temperature dependencies of the heat capacities of gaseous F[subscript 2] and N[subscript 2]. For F[subscript 2], C[subscript p,m] increases from 300 K, reaches a maximum at 2200 K, and then decreases to 74% of the maximum…

This article provides two activities, exploring genetic drift of small breeding populations, highlighting the black-footed ferret ("Mustela nigripes"). According to the U.S. Fish and Wildlife service, all black-footed ferrets are descended from 18 individuals, making them extremely vulnerable to genetic drift. They were thought to be…

GRANTISM (GReenland and ANTarctic Ice Sheet Model) is an educational Excel™ model introduced by Pattyn (2006). Here, GRANTISM is amended to simulate the Svalbard-Barents-Sea Ice Sheet during the Last Glacial Maximum, an analogue for the contemporary West Antarctic Ice Sheet. A new name, "GRANTSISM," is suggested; the added S represents…

A fun activity is presented using singing wine glasses for introductory physics students. Students tune a white wine glass and a red wine glass to as many semitones as possible by filling the glasses with the appropriate amounts of water. A smart phone app is used to measure the frequencies of equal-temperament tones. Then plots of frequency…

Discusses how computers can help students learn to design experiments, collect data, and quickly analyze that data both mathematically and graphically. Demonstrates some of the capabilities of the spreadsheet for these purposes with examples of data from gas law experiments. (JJK)

Describes two types of star charts commonly available for astronomical viewing and outlines a strategy by which teachers can have students use a computer spreadsheet to prepare their own easy-to-use star charts appropriate for the location, date, and time of viewing. (Author/MKR)

Describes combining the simple activity of collecting monthly student height measurements with the technology of using a computer spreadsheet for a year-long activity that teaches measurement and data manipulation. (PR)

Describes how spreadsheets can be used for helping students learn about direct current electrical circuits. (PR)

Describes a two-week lesson on electric fields that combined lecture, interactive video, lab experimentation, computer spread sheets, and computer-assisted-graphing. (PR)

This document contains the fifth volume of the proceedings of the 30th Conference of the International Group for the Psychology of Mathematics Education. Conference presentations are centered around the theme "Mathematics at the Centre." This volume features 59 research reports by presenters with last names beginning between Sac and Zaz:…
