Abstract: Over the last 20 years, our learning environment for mathematics has changed dramatically, and mathematical tools now have an important role in our classrooms. Sage is the popular mathematical software which was released in 2005. This software has efficient features to adapt to the internet, and it can describe most mathematical problems: for example, problems within algebra, calculus, linear algebra, combinatorics and numerical mathematics. Nowadays, there are more mobile devices than personal computers all over the world. Furthermore, the most sophisticated Smartphones have almost the same processing power as personal computers and can connect to the internet easily. For example, we can connect from a mobile phone to any Sage server through the internet. We have developed our mobile infrastructure of Sage in the mobile-learning environment and have utilized it in our teaching of mathematics with Smartphones (Ko et al., 2009; Lee & Kim, 2009; Lee et al., 2001). In this paper, we introduce how to develop our Mobile Sage environment and features of Sage Graphers that have been developed using it (http://matrix.skku.ac.kr/mobile-sage-g/sage-grapher.html).

Key words: sage, mobile sage, mobile mathematics, graphing calculator, visualization
