This document discusses the SlideShare tool, which allows users to share virtual presentations publicly or privately in various formats like PowerPoint, OpenOffice, PDF and Word. It maintains copyright and protects personal information. The author suggests using SlideShare in teaching by having learners express ideas creatively and autonomously to generate interaction and experiences that promote knowledge acquisition. Learners can actively participate, think and discuss in a real virtual environment, supporting an excellent learning process by exposing individuals to different socio-cultural contexts and topics. SlideShare is also useful for teaching English as it supports learning outside the classroom and can be adapted by teachers for different environments and topics while providing direct contact with the language.
