Abstract:

Currently, digital natives are more receptive to using mobile devices for learning than traditional methods. One of the fields in which the learning approaches has advanced to a lesser extent is that of mathematics, especially for pre-university learning. Obviously, sheets and calculation programs are used, but not “real” multi-touch applications.

We have recently developed an approach that allows the resolution of a system of linear equations in a tactile graphical environment in which students can learn easily, through intuitive ways as well as trial and error. This technology, DNT (Digital Numbers Technology) can be used as a resolution way to solve linear equations in itself, or as an addition to the traditional approach that helps to understand the underlying numerical relationships between the variables. In previous studies this approach has been used in finance, physics or engineering.

In a simple linear equation DNT gives all the answers in a visual way. In the case of a system of two equations with two unknowns the three methods usually used for their resolution are: reduction, substitution or equalization. We have developed an interactive graphical system for each type of resolution. In this way the student has a clear and easy method of learning, and the teacher an educational instrument that facilitates student engagement. On the other hand, this method can greatly help students who present disabilities in the field of mathematics.
