Designing and Implementing a Video Game to Assist Teaching-Learning Process of Numerical Expressions

Nowadays, there has been a real change in the traditional methodology for learning and teaching; the teaching of mathematical subject needs to identify the real necessities of students to avoid deficiencies in static classrooms. The benefits of the digital game based learning approach as a learning paradigm are widely recognized, because they support learning environments where students are actively related in implementing their own knowledge; passing through passive to active learning states. This article describes the development of an educational video game that aims to help first semester high school students to improve their understanding of the Numerical Evaluation of Algebraic Expressions.The game is verified by testing to ensure that the graphic and textual components show the correct communicability interfaces and transmit efficiently the intent of the educational content. The results of communicability testing were analysed on the same day and show that interfaces with greater communicability problems were those that concentrate more on graphical and textual components.
