A general analysis of reaction mass efficiency and raw material cost is developed using an Excel spread sheet format which can be applied to any chemical transformation. These new methods can be easily incorporated into standard laboratory exercises.

This guide was developed as a "how to" training device for obtaining help with AppleWorks version 2.0 word processing files using the Apple IIGS computer with two disk drives. Step-by-step instructions are provided for program loading; selecting the help list; and using the help list to copy text, delete text, find parts of a document,…

Budgeting is a valuable planning tool, facilitated by basic spreadsheets. Three basic steps in creating a budget--listing fixed and variable costs, computing a break-even point, and evaluating modifications--are explained. Models illustrate the basics of moving around the spreadsheet and entering formulas. Popular spreadsheet programs and price…

Describes the use of the partially prepared template for solving selected accounting problems and examines the educational issues relating to students' perception of using them. (JOW)

This paper shows how the computational and graphical capabilities of spreadsheets allow for interactive analytic and geometric constructions from numerical modelling of homogeneous Diophantine equations of the second order. Suggested activities, designed for prospective teachers of mathematics and made possible by what is referred to in the paper…

A spreadsheet simulation of a modern particle detector has been developed and can be readily used as an instructional tool in the physics classroom. The spreadsheet creates a three-dimensional model that can be rotated and helical trajectories can be highlighted. An associated student worksheet is also presented.

A Lattice Energy Spreadsheet by Christopher King, which can help instructors and students to easily calculate crystal lattice energies in many binary compounds, is introduced.

A simple interface between VPython and Microsoft (MS) Office products such as Word and Excel, controlled by Visual Basic for Applications, is described. The interface allows the preparation of content-rich, interactive learning environments by taking advantage of the three-dimensional (3D) visualization capabilities of VPython and the GUI…

To reach a sustainable world the use of renewable energy sources is imperative. Photovoltaics (PV) is but one of the technologies that use the power of the sun and its deployment is growing very fast. Several master programs have been developed over the world, including Utrecht University, that teach these technologies. Within the framework of a…

The outline for half of a one-credit-hour course in analysis of chemical engineering data is presented, along with a range of typical problems encountered later on in the chemical engineering curriculum that can be used to reinforce the data analysis skills learned in the course. This mini course allows students to be exposed to a variety of ChE…

This article briefly describes the topics "beta coefficient"--a measurement of the price volatility of a company's stock in relationship to the overall stock market--and "market share"--an average measurement for the overall stock market based on a specified group of stocks. It then selectively recommends a database (file) on…

This digest discusses using spreadsheets in mathematics education. The case is made that being able to manage spreadsheets is an important skill in the technologically enhanced new millennium. An annotated list of World Wide Web resources is included. (MM)

Describes the use of a Lotus 1-2-3 spreadsheet to provide students in a networked microcomputer lab with up-to-date information on grades and attendance. (SK)

Presents exemplary material from the publication "From Little Acorn Grow--Spreadsheets 9 to 13," a photocopiable resource book that contains spreadsheet ideas. Highlights the process of preparing the publication. (JRH)

Describes the development and instructional use of a Microsoft Excel spreadsheet template that facilitates analytical and Monte Carlo risk analysis of investment decisions. Discusses a variety of risk assessment methods followed by applications of the analytical and Monte Carlo methods. Uses a case study to illustrate use of the spreadsheet tool…
