MicroWorlds is a family of computer programs developed by Logo Computer Systems Inc. (LCSI) that uses the Logo programming language and a turtle-shaped object to teach language, mathematics, programming, and robotics concepts in primary and secondary education. The program was part of a larger set of dialects and implementations created by Seymour Papert aimed at triggering the development of abstract ideas by children through experimentation.
MicroWorlds was first released in 1993 for MS-DOS and Classic Mac OS computers, and in 1996 for Microsoft Windows. The program became incompatible with macOS 10.15 and higher due to requiring 32-bit architecture. Support for the program on Windows ended 30 November, 2023 and LCSI on announced a browser-based program called Lynx would be the program's replacement.
