Math learning materials combining print materials and web based training

This paper presents a new type of math learning materials which combines print materials and web materials. By reading a two-dimensional bar code on the print material with a mobile phone camera, students are able to access the web materials easily. The print materials are used to avert the problems of inputting equations into computer and to promote the writing of equation in the process of answering. The web materials are used to ensure the efficient learning through the reference to the linked pages one after another.
