Abstract:

Mobile devices have had a great development in recent years and they are influencing all the activities. For this reason groups like New Media Consortiumy Learning Initiative, in their Horizon Projects Report, they point out, as one of the lines of research to develop in recent years, the use of mobile devices in education.
Additionally, there is educational software, that is built especially for mobile devices, developed for different purposes: fun, acquire skill in a topic, submit information about a course, puzzle-solving, etc. These materials are disorganized and there is not a study on how they can influence the teaching-learning process (ASP). Because disciplines like educational mathematics allows to perform a research that links the technology and the theoretical work on learning, to investigate how to take advantage of these devices within a classroom.
The purpouse of this work is to take both disciplines, the mobile computing and educational mathematics, and apply them to the teaching of the calculation, focusing to the concept of function.
In the present paper we show a proposal to teach the concept of function using mobile computing. This proposal is based on educational theories such as constructivism, problem-based learning and augmented reality.
This article is organized as follows, in the first part we show some difficulties that students have in the first semester at college level while working such concept. The second part describes the application designed to be used in mobile devices by students anywhere, everywhere and at any time showing the function concept. The proposed activities are part of an educational methodology, here is shown the diagnostic questionnaire as one of the basic methodological tools and the application to mobile devices.
