Engineering students have traditionally had a lot of difficulty in reaching the objectives they have to cover, established in the different [Mathematics] courses. In a distance learning an onlineon-line environment, both the learning methodology and the students’ profile (adults with family and professional responsibilities and with usually insufficient previous knowledge levels) are elements which aggravate these difficulties. In particular, it is mathematical notation which is necessary and ubiquitous in this kind of learning that presents a problem for the expression of content: verbalization is not a simple task and it is not easy to write using common digital resources. This second factor is especially significant in distance learning.

A mathematical expression verbalization tools have been developed with the goal of improving teaching quality in courses requiring scientific and technical notation unknown to many students. These tools have been integrated in web-based learning onlineon-line study material, written in MathML, pertaining to a basic mathematics course for engineering at the UOC (Universitat Oberta de Catalunya). A first test with a group of students has been carried out with very satisfactory results.

Because of this initial success, we believe that this application improves the communication competences of students in courses with high mathematical content, reducing semantic confusion and so easing communication between students and teachers. From a technological point of view, it means including a new functionality to a formulae editor based on the MathML standard.
