metaStudio for semantic networks and concept maps

This is the second post on metaStudio featuring the special features of gnowsys-studio.

The site allows collaborative construction of semantic networks between the wiki pages.  Users can define and use the relations between pages.  The graph produced is published in SVG which allows navigation of the graph by mouse click.  When Control + Click is used the graph reloads on the same page showing the additional nodes in the neighbourhood of the selected node. This way, a merged graph can be created.   Explore more pages at the site.

Free Software for Science and Mathematics Education

Last three days (12th – 14th of November 2009) our Centre invited teachers and students from around Mumbai to share our work with the public (Vigyan Vividha). During this program the team members of gnowledge.org lab demonstrated several free software applications that can be used for science and mathematics education.  We did demonstrations of several of them to hundreds of visitors. Though we showed several applications, our focus was on the following selected applications.

• Phoenix (Computer Interfaced Science Experiments)
• Step (An interactive physics simulator, part of KDE-EDU package)
• GeoGebra (A dynamic Geometry and Algebra Platform)
• KTurtle (A simple turtle graphics program using LOGO for children)
• Inkscape (An advanced vector (SVG) graphics editor)
• Stellarium (A planetarium for your computer)

Many of them are well known, except Step.  I want to therefore say few words about it.  This program will have a great role to play for physics education. An excellent platform for learning as well as teaching.  If you are a physics teacher or an educator, consider using Step.  Though the program needs several finishing touches (sometimes eats up resources while simulating complex systems), the author (Vladimir Kuznetsov) is ambitious and did a fantastic job.  Once this program is improved, it will be a classic tool for education in the high school and college level physics.

Geogebra also gives the same experience for mathematics.

These are all free software for education.  I encourage teachers to use them in the classroom, and students who own a PC must install GNU/Linux on their PCs and enjoy these applications among several others.
