<answer>

Basic Use Examples

<answer> is an Evaluation component that defines content for which the user is awarded credit or is required to provide a response.

The following examples illustrate some of the basic answer forms.
See the following pages for more complex examples, attributes and properties.

Example: Default math <answer>

<p><m>7x + 3x = </m><answer>10x</answer></p>

Note that, by default, any expression that is mathematically equivalent to $10x$ is considered correct, so the user can type the given expression and receive full credit in this case. See further examples on how to refine this behavior.

Example: Default text <answer>

<p>Type <c>banana</c>: <answer type="text">banana</answer></p>

Value entered into the <textInput/> must match exactly (default is case-sensitive) to the provided response, excluding white space at the beginning and end.

Example: <answer> with multiple awards

One or more <award> components enclosing correct responses may be nested inside an <answer> component to give credit for different answers. Individual awards may also have different credit values assigned, see further examples on how to refine awarding for partial credit.

Example: <answer> with basic logic

This example illustrates the use of some simple validation logic that can be constructed with an <answer> tag that references a named <mathInput/>. Credit is awarded when the boolean contained within the <when> component evaluates to true. Multiple <award> components may also be used for answers with more complex validation logic.

Example: <answer> for graded free-response

<p>Explain how you solved the problem: 
  <answer type="text" handGraded expanded forceFullCheckworkButton />
</p>

The handGraded attribute defers grading for a human to score later. When combined with the expanded attribute of a text answer, the result is a graded free-response style question. The forceFullCheckworkButton attribute was added just for aesthetics.
