• Chose the "Input type". Algebraic input is a good general type and accepts algebraic as well as numeric input. The other Input types are advanced features.
• Type in your "Model answer". This can be an expression or good practice suggests defining the correct answer as a Question variable and you can enter the Question variable as the model answer.
• Optional: Chose the settings you require for the answer settings.

Potential response tree

The potential response three is where you build the automated feedback to the students. This guide will focus on creating and managing simple behaviour of the nodes.

The Potential response tree is created by through a series of true/false conditions. If a student's response matches a condition the tree follows the green arm of the branch or if it doesn't match the tree follows the red arm. When the logic reaches a [stop] command the accompanying feedback is given.

Node 

Answer test: This is the type of comparison the node will compare the student's answer against a test condition such as algebraic equivalence, number of significant figures, partial fractions etc. There are a large variety of conditions which are beyond the scope of this document.

SAns: This is where you enter the variable for the students answer and will generally be ans1 from the question text field. If you have set up the question with multiple inputs you will need to chose the correct student answer variable as you will then be creating multiple Potential response trees.

TAns: This is the reference answer you wish to compare the student's answer against. Typically for the first node it will be the same as the model answer. Many of the reference answers will be typical mistakes students make and so the TAns will be pre-determined incorrect answers.

Test options. Many of the Answer tests require options to be defined. For example, if you are testing for significant figures you will need to define this in the Test options.

Quiet. This option determines whether the feedback is displayed. No means it is not quiet and hence displayed.
