Adding a highlighter for text selection.

By clicking Highlight highlight on the Cell Editor toolbar, you can create interactions where the learner uses colour markers to highlight words or letters.

 

Note:  Do NOT enter text in the Cell Editor, wait until you are inside the Highlight Editor before typing any text.

 

The Highlight Interaction Editor

highlight tools

The Highlight interaction editor is a little different to that for other interaction types.

Create a Cell then double click on it to start the Cell Editor.  Now click once on the Highlight button highlight to add Highlight functionality to your Cell.

 

Double click on your newly positioned Highlight icon to see the Highlighter Editor options.  In here you select which colours will be available to the user. The colours and their order are fixed, but each interaction can have its own selection of colours in use.

 

The number of rows within the Interaction Table is fixed to the number of available highlight colours. You should only modify the Positive, Negative, and Unanswered feedback texts. (See below for how these texts get used when marking an interaction.) The Label fields for the options are ignored.

 

You may choose whether the highlighting should apply to words within sentences, or letters within words. If you choose highlighting by letter, you can choose to add padding spaces around each letter, to make it easier to highlight the individual letters.

 

Below the interaction table is the Source text area, where you type the text to be used for the highlight interaction.

 

When you have entered the Source text, click on  Master master. This will copy the entered text and display it in the Mastering box. The Mastering box includes the highlight colours that will be available to the user, and formats the text as  will appear to the user.

 

In the Mastering area, select your word(s) and use the highlight colours to define the correct (master) answer.  Note: You must click on Master before clicking Ok for your changes to apply.

 

If you wish to remove highlighting from the Mastering area and start over defining the master answer, click on Clear.

 

When you have finished defining the interaction, click Ok to save the interaction.

 

 

Source Text Formatting

The Source text area attempts to maintain some layout information, including new-line and spaces.

 

If you wish to add additional formatting to the text, please enter HTML codes directly. Useful codes may include:

Format

Text to type

 

Text as displayed

Boldface

This is <b>bold</b> text

 

This is bold text

Italics

This is <i>italic</i> text

 

This is italic text

Bulleted list

<ul> <li>One</li> <li>Two</li> </ul>

One
Two

 

 

Ignored Text

When defining the correct answer in the Mastering area, you can use the Ignore highlight colour to mark text that is ignored. Ignored text cannot be highlighted by the user.

 

Word Groups

You can combine words into a single group by using the underscore (_) character. The words are displayed individually, but are highlighted together when the user clicks on any one of the group.

 

For example, “The quick_brown_fox jumps” is displayed as “The quick brown fox jumps”, and when the user highlights any of the words “quick”, “brown”, or “fox”, all three are highlighted together.

 

Marking

The Out Of score in a highlight interaction should be set to the number of highlighted texts. For example,

The quick brown fox jumps over the lazy dog.

should be marked out of 2. Similarly,

 I  n  c  r  e  d  i  b  l  e 

should be marked out of 2.

 

However, This does make it possible for the user to achieve full marks without getting the answer completely correct. For example, if the user has highlighted

The quick brown fox jumps over the lazy dog

then the score achieved will be 2, but the answer is not yet correct. The Retry button remains visible as long as any part of the interaction is incorrect.

 

If the user does not highlight any of the interaction text, the whole interaction is marked as Unanswered beside the highlighter boxes.

 

Notes:

The marking of interactions, and the feedback provided to the user, is different depending on whether the interaction is by letter, or by word.
By-Letter feedback text is determined by the user’s highlighting.
By-Word feedback text is taken from the author’s master answer highlighting.

 

 

By-Letter Interactions

When marking by-letter interactions, each “stroke” (i.e., group of consecutively highlighted letters) of the highlighter is treated as a single unit. The highlighter stroke is marked Correct if the user has marked all of the correct letters and not included any letters in the highlighted colour.

 

The user’s answer can thus be marked Wrong for three different reasons:

The user has highlighted using the wrong colour.
The user has highlighted more letters than there should be for that stroke.
The user has highlighted too few letters for that stroke.

If the user has failed to highlight a stroke that should be highlighted, that stroke will be marked with an Unanswered icon.

 

When marking by-letter interactions, the feedback text is determined by the user’s highlight colour. The negative feedback text should be kept general, since the author doesn’t know which of the above cases caused the stroke to be marked incorrectly.

 

By-Letter Feedback Example

Given a by-letter Interaction Table with the following feedback texts:

2:

The feedback to the user in a number of different cases is illustrated in the table below:

Building a By-Letter Interaction

In this example, we create a highlight interaction where the user is to mark prefixes and suffixes of words.

1.Double-click on the page to create a new cell.
2.On the cell editor toolbar, click on highlightHighlight to insert a new highlight interaction.
3.Click on the highlighter colours to keep only green and blue colours. (The interaction table won’t change.)
4.From the options, select Letters, and check that Pad Letters is ticked.
5.In the feedback text table, type in the desired feedback text
6.In the Source area, type the words below. Note that we can use carriage returns and spaces to lay out the words like a list, without needing html codes.

- Engaged
- Learning

7.Click on Master master to copy the text to the Mastering area. Note that, because we selected Pad Letters, extra spaces have been added between the letters.
8.In the Mastering area, use the highlight colours to mark the master answer. Since the highlight interaction does not distinguish letters from punctuation, you may wish to mark the list bullets to be ignored.

 -   E  n  g  a  g  e  d 
 -   L  e  a  r  n  i  n  g 

9.Since you have marked three groups of letters, set the Out Of to 3.
10.Click Ok to save the interaction.

 

By-Word Interactions

When marking by word (or word group using the underscore character, see above), each word is treated as an individual entity and marked depending on whether the highlighter colour is correct.

 

When marking by-word, the feedback text is taken from the master answer. This allows for more constructive feedback when the user has used the incorrect colour to highlight interactions.

 

 

Feedback Text Example

Given a by-word interaction table with the following feedback texts:

Label

Negative

Unanswered

Mark nouns yellow



ƒAttempt to answer this question

The feedback to the user for a number of different cases is shown in the table below:
