This idea has attracted some interest in both science and mathematics in secondary schools. Each of the calculator manufacturers also provides support for, and examples of, data loggers for schools, with the emphasis on their use in science. For example, the data logger shown above is the EA-100 for Casio calculators, for which there is a collection of support materials for science teachers. Colin Croft has provided a number of science applets for the HP-38G calculator for teachers and their students to try out. Calculator-based data loggers from different companies share many of the same characteristics, but also have a few differences.
Data loggers have some significant advantages for collecting data.
These sorts of things are discussed a bit in an article I wrote recently for Scios , the journal of the Science Teachers Association of Western Australia .
