Binary tree

This is an example of a binary (2 option) decision tree taken from ELSAC's exercises.
It contains options and responses. When the student chooses an option they a given another question (a response) to guide them through. Once they get to the end of a branch they will be given a final response which in this case is instant feedback if they have chosen the correct path or not.

Multi-node tree

This is an example of a tree that contains nodes with multiple options in this case 7 options.
There are few limitations to the tree:

• If you allow the editor to choose random node name you are limited to 100 nodes (however you may name all nodes you will escape this limitation)
• If you fill the viewable area of the tree it is possible to extend the viewable area, however not that once the area is wider than the content area of CourseBuilder, scrollbars will appear.

Using HTML

Here are some examples of HTML in the nodes.
You'll notice the root node has text color applied, bold text and tooltips.
You'll also find some links to external sites in some nodes.
One of the leaves (last node in a branch) contains an image.

Links beween trees

It is possible to link from one tree to another.
There are several reason why you may want to do this.
If the tree you wish to create is very large, you can break down the large tree into smaller trees and link the end of one tree to the root of another.
Another reason for linking trees is to allow students to go from one tree to the next without having to use the next/previous button. This mean a student may be directed to another tree in a non-linear order depending on the result of their decision.

Points reward

For students to keep track of their progress, you may add a points reward system.
This will keep a running total of the points depending on which node the student chooses.
It is also possible include negative points for incorrect choices.

NOTE: it is not possible to keep a formal record of these points and should NOT be used for any formal assessment.

Star reward

For students to keep track of their progress, you may add a star reward system.
This will keep a running count of how many nodes they have correctly chosen.

NOTE: it is not possible to keep a formal record of these points and should NOT be used for any formal assessment.

Chart

In this example, the option "Display as a chart" is checked. This forces all the nodes in the tree to be shown as soon at the tree is loaded. This feature can be used for an organisation chart of example. The only limitation is the structure must be a tree.
