When I was in high school, during IT classes we worked with DOS, WordPerfect for DOS and BASIC. When my sister showed me her school textbook ‘Information technologies for gymnasium’, I was expecting tons of Windows screenshots. But, I was surprised. Look at those:
Wow! Not only there are Ubuntu screenshots and big Wilber, no… The textbook explains what is Open Source, what are proprietary operating systems. You can even find words like FreeBSD, NetBSD, EXT2, EXT3, UFS :) They equally provide space for Microsoft Windows Vista, XP and Ubuntu Linux (no MacOSX). Granted, in the office section, they explain how to work with MS Office tools, but they acknowledge existence of OpenOffice.org, quoting ‘We were attracted by Microsoft Office 2007 and OpenOffice.org.’, providing links to OpenOffice.org (on each chapter about office tools) and manuals.
And that big Wilber isn’t just to fill in space - they actually have 10 pages long ‘manual’ on how to use basic GiMP tools! There’s no Photoshop section in the book. Only GiMP for bitmap editing - and it’s even provided on the DVD shipped with the book.
Gvozadnović, Ikica, Kos, Miljaš, Srnec, Sekulić-Štivčević, Zvonarek (authors of the textbook) - you really surprised me and kudos for this great textbook. If you can read Croatian, take a look at http://www.propyx.com/udzbenik/izbornik.
