Pownell and Bailey (2001) identify four “technological trends” in the relationship between Information and Communication Technologies and educational environments. In the 1960s the first computers, which were very large and extremely expensive were rarely used in the educational area. They were only used to help in administration and in management. In the seventies with the arrival of the personal computer, schools in several countries, as in the United States, introduced computer basic courses to help students learn the use of this new technology. In the nineties the large-scale diffusion of Internet and the World Wide Web lead to a huge number of people who communicated through a computer mediated communication. At last in 2000, extremely small computers were sold on the market and the era of wireless connections began. These two factors in the educational field encouraged the beginning and the development of mobile learning.
