again this year at the beginning of the school exploded the news of rising costs. The whole thing starts to become ritual: if they speak after the August holiday jams return and the Pima and financial maneuver of 'hot autumn .
Most textbooks cost concerns: huge publishing business revolve around school. The current model of production of textbooks has certainly the merit to finance the production of books, highly meritorious work, and to finance a large number of workers and thus provide for the livelihood of many families ...
But there is a doubt: the case for this method is not out of date?
new technology can produce self- materials of comparable quality, at least in some cases, from textbooks.
Why this does not happen? I can think of two reasons:

• The big economic interests that push for the maintenance of the current situation;
• The motivation of teachers less and less able to be active and productive.
  

Self-production of learning materials would undoubtedly greatly benefit the educational activities:

• Flexibility of materials, tools
• Adaptability to various situations;
• Upgradability continuous
• Save Money.

But to use materials self-published, we need a change of mindset: from passive users to producers. And a change of organization: the model can not work a single author, works are collaborative where everyone plays a part which can be:

• Write discussion of a topic ;
• Write verification exercises or questionnaires;
• Report errors, failures, improvements,
• Use the material in its business.

It is clear that such an organization is only possible within a model similar to that which develops free software and then with the use of licenses to use, modification, copying and distribution of original works or modified.

For my part I am working on a text for the computer lab with:

• OpenOffice.org,
• The Python programming language,
• Some Python libraries for the geometry of the turtle, Cartesian and interactive.

If every teacher put in a cauldron common and well-organized their work, perhaps the publishers would be pushed to do something more interesting to change titles and versions of the same test every three years.

About my book is better than I forgive proofread instead of continuing to write to myself.

At the insistence of my children, start a blog. I do not raise particular objectives, we will evolve as the "thing" ...

For now a big hug to all those who have arrived so far.
