Abstract:

Moodle is a system that allows making multiple teaching-learning activities for teachers and students through Internet, creating virtual workspaces, formed by information resources such as text format, photographs or diagrams, audio or video, web pages or Acrobat documents, among many others. The moodle architecture and tools are appropriated for online classes as well as b-learning.
Nowadays this system is used in some universities and one of the modules that it has is allow uploads the notes and tasks on the page, so students can download these files. On occasions when a teacher changes a task or certain notes, the student cannot realize these changes and neither where they were made.
With this project, we aim to create an application where registered students in a moodle course can receive notifications when there are changes to professor files and the student has the option to update these notes. This implementation would benefit, firstly the students from different universities, because it will have current information giving the teacher more comfort making a saving of time.
This application of the files update is added to moodle, will allow the students be always up to date with changes made by the professor to the notes which students have previously downloaded.
The system steps are:
1. Convert student, new and old professor file to xml
2. Compare the professor new and old file
3. Create a new file with professor changes
4. Merge the student notes file with the file produced in step 2
5. Create a new student file with student notes, professor old notes and new professor changes
To convert and compare files we use unix system calls.

By May we are going to apply an experiment with at least 70 engineering students in order to know the real benefits of this application at Universidad Autónoma Metropolitana in México City.
