Teaching and learning of mathematics are integral parts of societies throughout the world. The fundamental or core nature of mathematics, its compulsory acquisition, requires high quality mathematics learning experiences. Moreover it is highly desirable that the emergence of new technology positively influences learning experiences in mathematics. Since 81.5 per cent of countries in the world belong to developing countries, it is important that technology-based learning experiences are implemented in these countries. Based on a survey in Bojonegara Sub District, Indonesia, a prototype of modifiable and shareable electronic maps has been developed. This product would be useful for teachers mapping mathematical learning resources in the Internet for easy access and download for use for teaching and learning. The teachers could also create, modify and share the maps with others. (Contains 15 tables and 12 figures.)
