Immediate feedback – Cloze ordered

Use

• Where the user must choose an answer from two or more dropdown menus to complete the sentence. The order of the answers affects the sentence.

Source: Questions

This section describes the source code for how you would write the questions in HTML.

Example: <select name="q1" onchange="collectAns(1, 1, this.options[this.selectedIndex].value)">

Your select tags need to include the following attributes:

• onChange="collectAns(G, P, this.options[this.selectedIndex].value)" – where G is the group number (appears as question on screen) and P is the part number (which part of the group)

Consider each multiple cloze question as a 'Group' and each available response as an individual 'Part'. Therefore

• Group 1 has two parts which both require a correct answer.
• Group 2 has two parts which both require a correct answer.

In these examples the order of the answers is important.

Groups (questions) must always be numbered sequentially starting from 1. This does not mean that a question can't be seen as 'question 1a' to the user. There is no double-up of group numbers.

The number of parts relates to the group. In this example there are two groups: Each group contains two parts. Parts must always be numbered sequentially starting from 1 for each group.

There is always one image per group (a question on screen). Images must be named according to their group. For example, name="iq1" – i means image, q1 is the group it's attached to. The q is still used as opposed to g to retain the use of one universal startAgain() function for resetting. Images should start as blank.gif with an empty alt. The Javascript will change the image as appropriate.

Example: <img src="/learningplace/images/courses/interactive/blank.gif" width="18" height="18" name="iq1" alt="">

The Reset button must always include the following attributes:

• type="reset"
• name="Reset"
• value="Reset"
• onclick="startAgain(Z); resetVars(Z)" – where Z is the number of groups/images

Example: <input type="reset" name="Reset" value="Reset" onClick="startAgain(2); resetVars(2)">

Below is the source code for the example.

Source: Javascript

It's preferable to link to a separate Javascript file although, for pages individually loaded into Blackboard, including the script within the HTML is acceptable.

There are three parts of the script that need to be modified:

• Pre-loading of response image placeholders
• Setting the question variables
• Setting the response image variable paths

The response image placeholders must always start as blank.gif. Only change the value for the number of images – for (var i=1; i<=numberofimages; i++) {, and adjust the path to blank.gif – eval("iq"+i+".src = \"blank.gif\"");.

Set 2 new variables for each group as Arrays. The variables must appear as:

• var vqX = new Array("","Y","Y"); – where X is the group number and Y are the option numbers of the correct answers. There must be as many answers as there are parts (dropdown menus) in the question.
• var uqX = new Array("","0","0"); – where X is the question number and "0" are placeholders for the user's answers. There must be as many placeholders as there are answers.

Example: var vq1 = new Array("","3","4");
var uq1 = new Array("","0","0");

Set the paths of the response image variables as needed. Do not remove or rename these variables.

Below is the source code for the Javascript of the above example.
