Due to inherent factors like a small and fragmented market and rapid hardware obsolescence, the conventional textbook is inadequate for DSP laboratory education. Freely available open-content materials that enable and promote both local customization and further development by a community of educators offer a fresh approach to lab text development that can surmount these barriers. In this paper, we overview a joint effort under the aegis of the Connexions Project to develop a large pool of DSP lab modules sufficient to serve as a complete, stand-alone text for several types of DSP lab courses. In addition, we introduce a pilot project whose aim is to demonstrate the suitability of using Connexions for languages other than English, such as the Japanese, Chinese and Thai languages.
