This document discusses the benefits of shared lesson planning among teachers using information and communication technologies (ICT). Traditionally, lesson planning has been an isolated process for individual teachers. Shared lesson planning allows teachers to collaborate, build on each other's expertise, and continuously improve their lessons. When lessons are shared digitally using tools like documents and PowerPoint files, they can be easily modified, adapted, and standardized at a high quality level. Overall, the document argues that shared lesson planning facilitated by ICT can help teachers teach better and reduce the isolation of traditional lesson planning methods.
