| ==Answer box placeholders==
| | </p> |
| | |
| Answer box placeholders provide a simple way to arrange the answer boxes in the part's text. It is particularly useful when the subquestion requires more than one answer. This flexibility allows you to arrange the answer boxes in the form of a matrix, coordinates, embedding into the question text or any other way you want.
| |
| | |
| There are two answer box types: the quantity box and the unit box. The placeholder names are <span style="font-family:monospace;font-size:113%;">_0</span> for the first quantity box, <span style="font-family:monospace;font-size:113%;">_1</span> for the second quantity box, etc, and <span style="font-family:monospace;font-size:113%;">_u</span> for the unit box. The number of placeholder names that can be used is the same as the number of elements entered in the answer field, plus one if the unit is specified.

| <div style="font-family:Lucida Sans Unicode;font-size:150%;color:#f98012;margin:10px 0 10px;>Example</div> | |
| | |
| A subquestion that has two elements in the answer field and a common unit:
| |
| | |
| <pre style="font-size:113%;width: 98%;">
| |
| General
| |
| Question name ! Two quantity and one unit answer boxes
| |
| Main question
| |
| Question text ! Using answer box placeholders
| |
| Given: Point A is at position x = 100 mm and y = 200 mm.
| |
| Part 1
| |
| Part's mark* 1
| |
| Answer type Number
| |
| Answer* [100, 200]
| |
| Grading criteria* Absolute error == 0
| |
| Unit mm
| |
| Part's text Question: What are the coordinates of point A? The answer must be given as follows: '(x,y) unit'.
| |
| A(x,y) = ({_0},{_1}) {_u}
| |
| </pre>
| |
| | |
| The formulas question should look like this:

| |
| | |
| ''Each answer box placeholder can only be used once in a part.'' For example, none of the following will be accepted: | |
| | |
| <pre style="font-size:113%;width: 98%;">
| |
| Part's text {_0}{_0} Comment: {_0} can not be used twice
| |
| | |
| Part's text {_0}{_1}{_1} Comment: {_1} can not be used twice
| |
| | |
| Part's text {_0}{_u}{_1}{_u} Comment: {_u} can not be used twice
| |
| | |
| Part's text {_3}{_3} Comment: {_3} can not be used twice
| |
| </pre>
| |
| | |
| The placeholder names do not have to appear in any particular order such as the increasing order {_0}{_1}{_2}...{_u}. The order of the quantity boxes and the unit box correspond to the order of the placeholder names in the part's text. For example, the following:
| |
| | |
| <pre style="font-size:113%;width: 98%;">
| |
| Part 1
| |
| Answer* [0, 100, 200, 300]
| |
| Unit mm
| |
| Part's text {_2}{_0}{_3}{_u}{_1}
| |
| </pre>
| |
| | |
| gives
| |
| | |
| [[File:En29FormulasDocumentation04.png|680px]]
| |
| | |
| Neither do the quantity answers have to be in increasing order (of course) and we would get exactly the same as above with the following:
| |
| | |
| <pre style="font-size:113%;width: 98%;">
| |
| Answer* [200, 0, 300, 100]
| |
| Unit mm
| |
| Part's text {_0}{_1}{_2}{_u}{_3}
| |
| </pre>
| |
| | |
| By default, all missing placeholder are automatically appended at the end. For example, <span style="font-family:monospace;font-size:113%;">{_0}{_u}</span> for a one answer sub-question and <span style="font-family:monospace;font-size:113%;">{_0}{_1}{_u}</span> for a two answer sub-question.
| |
| | |
| The box <span style="font-family:monospace;font-size:113%;">{_0}</span> corresponds to the special variable <span style="font-family:monospace;font-size:113%;">_0</span> in the Grading variables.
| |
| | |
| ===Quantity and unit boxes side by side or merged===
| |
| | |
| When the quantity placeholder <span style="font-family:monospace;font-size:113%;">{_0}</span> and the unit placeholder <span style="font-family:monospace;font-size:113%;">{_u}</span> are directly side by side, such as <span style="font-family:monospace;font-size:113%;">{_0}{_u}</span>, the quantity box and the unit box merge into a longer single answer box in which both quantity and unit must be entered.
| |
| | |
| When the quantity placeholder and the unit placeholder are not directly side by side, i.e. when they are separated by a space or any other string of characters, the answer boxes do not merge and hence they are displayed side by side.
| |
| | |
| <div style="border:1px solid #bce8f1;border-radius:4px;padding: 0px 15px 0px; margin:20px 0 25px;">

| <div style="font-family:Lucida Sans Unicode;font-size:150%;color:#f98012;margin:10px 0 10px;>Example</div>

| Answer with both quantity and unit:
| |
| | |
| <pre style="font-size:113%;width: 98%;">
| |

| ==Width of answer boxes==
| |
| | |
| The width of the quantity and unit boxes, both separate and merged, can be adjusted by modifying the width parameters in the <span style="font-family:monospace;font-size:113%;">styles.css</span> file for the Formulas question as shown below. This change can readily be done by your Moodle site administrator.
| |
| | |
| <code css>
| |
| | |
| /* Set the width of the unit box to 150px: */
| |
| input.formulas_unit {
| |
| margin: 0.em 0 0 0;
| |
| width : 150px;
| |
| }
| |
| | |
| /* Set the width of the quantity box to 130px: */
| |
| input.formulas_number {
| |
| margin: 0.em 0 0 0;
| |
| width : 130px;
| |
| }
| |
| | |
| /* Set the width of the box for merged quantity-unit to 250px: */
| |
| input.formulas_number_unit {
| |
| margin: 0.em 0 0 0;
| |
| width : 250px;
