The itemBody section is where the question text, interactions, buttons and feedback are defined. Questions, solutions, etc will vary hugely depending on the question being asked, but I have included some standard sections that tend to be used regularly.

## Question Text

Question text displaying an equation using variables defined using Maxima in templateProcessing:

<div class="QTEXT"> <p>Solve the equation <m:math display="block"> <m:mrow> <m:mi>mLHS1</m:mi> <m:mo>=</m:mo> <m:mi>mRHS1</m:mi> </m:mrow> </m:math> giving your answer as an integer or as a fraction in its lowest terms. </p> </div>

### Displaying Variables

**Maths variable: **`<printedVariable identifier="mVar"/>`

**Integer:** `<printedVariable identifier="oQansVars" format="%.0f"/>`

**Number** (to 2 decimal places – change the number before the f in the format attribute to change the number of decimal places): `<printedVariable identifier="oQansVars" format="%.2f"/>`

## Interactions

### Text/numerical entry interaction

<textEntryInteraction responseIdentifier="RESPONSE" expectedLength="2" />

### Mathematical expression entry interaction

<customInteraction id="customInteraction1" ma:syntax="text/x-maxima" ma:printIdentifier="printMath" responseIdentifier="RESPONSE"/>

### Show Hint button

<feedbackBlock showHide="show" identifier="askhint" outcomeIdentifier="ASKHINT"> <p> <endAttemptInteraction responseIdentifier="HINTREQUEST" title="Show Hint"/> </p> </feedbackBlock>

### Show Solution button

<feedbackBlock showHide="show" identifier="asksolution" outcomeIdentifier="ASKSOLUTION"> <p> <endAttemptInteraction responseIdentifier="SOLREQUEST" title="Show Solution"/> </p> </feedbackBlock>

## Feedback

### Correct

<feedbackBlock outcomeIdentifier="FEEDBACK" identifier="RESPONSE-CORRECT" showHide="show"> <div>Correct</div> </feedbackBlock>

### Incorrect

<feedbackBlock outcomeIdentifier="FEEDBACK" identifier="RESPONSE-INCORRECT" showHide="show"> <div>Incorrect, try again. <br /><br /> </div> </feedbackBlock>

### No answer entered

<feedbackBlock outcomeIdentifier="FEEDBACK" identifier="RESPONSE-NULL" showHide="show"> <div>Please enter an answer<br /><br /></div> </feedbackBlock>

### Hint

<feedbackBlock identifier="HINT" outcomeIdentifier="FEEDBACK" showHide="show"> <div>Solution goes here<br /><br /></div> </feedbackBlock>

### Solution

<feedbackBlock identifier="SOLUTION" outcomeIdentifier="FEEDBACK" showHide="show"> <div>Solution goes here<br /><br /></div> </feedbackBlock>

## MathML

I won’t cover MathML in any detail here, but the University of Edinburgh’s LaTeX to MathML converter is a very useful tool to help with this. This section contains a few tips for achieving some things that aren’t immediately obvious in MathML.

### Greek Letters in MathML

These must be represented by the HTML decimal (e.g. Α) or hex codes (e.g. Α), not the HTML entity codes (e.g. Α). Here’s a full list of codes.

### Operators in MathML

**Times symbol:** `<m:mo>×</m:mo>`

**Space:** `<m:mi> </m:mi>`
