Economics of learning Piotr Wozniak, December 1994
Economics of Learning, the doctoral dissertation by Dr Piotr Wozniak, has laid a theoretical foundation for developing SuperMemo 8 for Windows (and its successors). The full text of the dissertation can be found on SuperMemo CD-ROM titles (e.g. Advanced English 97, Cross Country, Video English or MegaMix 99). Below only the most important or influential texts are presented (often hyperlinked to newer or more detailed texts). Small italicized hyperlinks in parentheses suggest and alternative more up-to-date reading
