Educational
software Introduction
Ubuntu for education
With
a wide range of educational software and certified hardware, Ubuntu provides
secure, cost-effective, accessible computing for students, teachers and school
administrators.
What is Edubuntu?
The Edubuntu Project
Edubuntu
is a grassroots movement, we aim to get Ubuntu into schools, homes and
communities and make it easy for users to install and maintain their systems.
We
are students, teachers, parents and hackers who believe that learning and knowledge
should be available to everyone who wants to improve themselves and the world
around them.
Our Goals
Our
aim is to put together a system that contains all the best free software
available in education and make it easy to install and maintain.
An Ubuntu Project
The
majority of the technical work that the Edubuntu team performs occurs within
the Ubuntu project. All the packages we work on are available in the Ubuntu
software repositories and the Edubuntu DVD is built from the exact same
repositories as the Ubuntu discs and other official derivatives.
More about Ubuntu
To
learn more about Ubuntu, visit the
Ubuntu website and read about it on Wikipedia.
Other Free
Software in Education Systems
There
are other educational systems besides Edubuntu. Some have different goals, we
try to collaborate with other systems where possible. There is a list of other education systems on
this page.
Good
educational software is hard to come by. And with ever-tightening budgets, it
only makes sense that many schools are turning to Linux and open source
software to save money. Most people have no idea how many outstanding
educational applications there are for the Linux operating system. In the
following list, you should find at least one application that's just right for
your situation
GeoGebra
Is a multi-platform mathematics software
that gives everyone the chance to experience the Extraordinary insights that math makes
possible
What is GeoGebra
GeoGebra is
open source dynamic mathematics software for learning and teaching at all
levels. This manual covers the commands and tools of GeoGebra 5.0. Depending on your
hardware and preferences, you can currently choose between 5.0
Desktop and the 5.0
Web and Tablet App, which feature minor differences in
terms of use and interface design.
GeoGebra’s User Interface
Views and Perspectives
GeoGebra provides different Views for
mathematical objects:
Each View offers its own Toolbar that
contains a selection of Tools and
range of Commands as well
as Predefined Functions and Operators that
allow you to create dynamic constructions with different representations
of mathematical
objects.
Depending on the mathematics you want to
use GeoGebra for, you can select one of the default Perspectives (e.g. Algebra
Perspective, Geometry
Perspective). EachPerspective displays those Views and other
interface components most relevant for the corresponding field of mathematics.
Other Components of the User Interface
You may also customize GeoGebra’s user
interface to match your personal needs by changing the default Perspectives and
adding other components:
Menubar
This component is part
of GeoGebra user interface.
The Menubar is always
situated in the top part of GeoGebra window. For applets it can be switched on
and off during export. It contains following
menus:
- File Menu
- Edit Menu
- View Menu
- Perspectives Menu (Web
and Tablet App Version only)
- Options Menu
- Tools Menu
- Window Menu (Desktop
Version only)
- Help Menu
Input Bar and Algebra Input
In GeoGebra Desktop, the Input Bar is by default located in the bottom of
GeoGebra window. You can show it or hide it using the View Menu or can change it's position within the GeoGebra window.
In the GeoGebra Web and Tablet Apps an Algebra Input is integrated directly into the Algebra
View. Therefore, the Input
Bar is not displayed by
default if the Algebra
View is part of the
GeoGebra window. However, the Input
Bar can be shown using the View Menu,
replacing the Input Field.
Both, the Input
Bar and Algebra Input are providing the same functionalities
in GeoGebra. However, the Algebra
Input additionally features
an Equation Editor, which
makes it easier for you to enter equations and expressions.
What
is the Style Bar
The Style Bar allows
you to quickly and easily change a selection of basic properties of Views or objects.
In order to open or close the Style Bar, either click on the little
arrow next to the name of the corresponding View in
GeoGebra Desktop, or click the Style Bar Button in the
GeoGebra Web and Tablet Apps. Please note that there are still more properties
you can change using the Properties
Dialog.
Style Bar Options for Views
Each View has
it’s own Style Bar options. In GeoGebra Web and Tablet App,
depending on the View you select, the Style Bar can
be opened by using one of the following Style Bar Buttons, and
displays the most useful options to the related View.
GeoGebra offers a Navigation Bar that
allows you to navigate through the construction steps of your GeoGebra
file.
The Navigation Bar is shown at the bottom of the Graphics View.
The Navigation Bar is shown at the bottom of the Graphics View.
To display it: Right click (Mac
OS: Ctrl-click) on an empty spot on the drawing pad, then select the
option Navigation Bar in the appearing context
menu or activate the option Navigation Bar for
Construction Steps in the Basic tab of the Properties
Dialog of the Graphics
View.
The Navigation
Bar
The Navigation Bar provides
a set of navigation buttons, and displays the number of construction steps
(e.g. 2 / 7 means that the second step of a total of 7 construction steps is
currently displayed):
- button:
go back to step 1
- button:
go back step by step
- button:
go forward step by step
- button:
go to the last step
- Play:
automatically play the construction, step by step
Note: You may change
the speed of this automatic play feature using the text box to the right of
the Play
button.
- Pause:
pause the automatic play feature
Note: This button only
appears after activating the Play button.
- button:
This button opens the Construction Protocol
Note: This button only
appears if option Button to open construction protocol is
enabled.
The
Context Menu
The Context Menu provides a quick way to
change the behavior or advanced properties of an object. Right click (Mac
OS: Ctrl-click) (or long-tap) on an object in order to open its Context
Menu. For example, it allows you to change the object’s algebraic notation
(e.g. polar or Cartesian coordinates, implicit or explicit equation) and to
directly access features like Rename, Delete, Trace
On and Animation On.
Note: If you open the
Context Menu for a point in the Graphics
View, it gives you the option Record
to Spreadsheet (only if the Spreadsheet
View is opened). Once selected, this feature allows you to
record the coordinates of the point in the Spreadsheet
View if it is moved.
Note: Selecting Properties
in the Context Menu opens the Properties
Dialog, where you can change the properties of all objects used.
The
Virtual Keyboard
The Virtual Keyboard of the GeoGebra
Desktop Version is a semi-transparent keyboard that is displayed on the screen
when the corresponding menu item Keyboard in the View
Menu is selected.
It contains the standard keyboard
characters, as well as the most used mathematical symbols and operators, and
can be used with a mouse or other pointing devices.
This makes the Virtual Keyboard
particularly useful when using GeoGebra for presentations or with multimedia
interactive whiteboards.
GeoGebra’s user interface also provides
a variety of dialogs.
Different accessibility features as well as keyboard shortcuts allow
you to access many features of GeoGebra more conveniently.

STELLARIUM
A stellarium is a three-dimensional map of the stars,
typically centered on Earth. They are common fixtures at planetariums,
where they illustrate the local deep space out to perhaps 50 light years. Older
examples were normally built using small colored balls or lights on support
rods (painted black to make them less obvious), but more recent examples use a
variety of projection techniques instead. Stellarium is a free open source
planetarium for your computer. It shows a realistic sky in 3D, just like what
you see with the naked eye, binoculars or a telescope.
It is being used in planetarium projectors. Just set
your coordinates and go.
