Pyramids in Logo: A School Project in 'Search' of the Fourth Dimension

摘要

In this paper we present a school project where students constructed three-dimensional pyramids using the Logo programming language, complemented with paper-and-pencil, dynamic geometry (Cabri) and spreadsheet (Excel) investigations. The aim of this project was to give, through a fun and meaningful way, and using a constructionist approach, junior secondary students (12-14 year olds), early access to advanced topics such the applications of the Pythagorean Theorem and of trigonometric functions, as well as three-dimensional work, while at the same time covering one of the themes included in the curriculum for this age-group (the pyramid).
