The Design and Development of a Simple Spreadsheet-Based Tool that Enables Students to Make Measurements on Astronomical Images

Abstract

This article describes the need for a software tool to make simple measurements on JPEG images, such as those obtained by students from robotic telescopes. Specifications for such software are given, followed by a description of a spreadsheet-based tool called the JPEG Viewer that was developed to meet these specifications. The main underlying aim was to enable students to carry out meaningful scientific projects using astronomical JPEG images. An evaluation is described of a project that involved students in measuring a spiral galaxy. Evidence is presented that it was successful in engendering interest, motivation, and understanding.
