adapt-contrib-gmcq

Graphical Multiple Choice Question (GMCQ) is a question component bundled with the Adapt framework.

It presents possible answers in the form of graphics or images. GMCQ is a variation on MCQ. It can be configured with a single correct answer or multiple correct answers. Upon submission, feedback is provided via the Tutor extension, if installed. Feedback can be provided for correct, incorrect and partially correct answers. The number of attempts allowed may be configured.

Visit the GMCQ wiki for more information about its functionality and for explanations of key properties.

##Installation

As one of Adapt's core components, GMCQ is included with the installation of the Adapt framework and the installation of the Adapt authoring tool.

• If GMCQ has been uninstalled from the Adapt framework, it may be reinstalled. With the Adapt CLI installed, run the following from the command line:
  adapt install adapt-contrib-gmcq

  Alternatively, this component can also be installed by adding the following line of code to the adapt.json file:
  "adapt-contrib-gmcq": "*"
  Then running the command:
  adapt install
  (This second method will reinstall all plug-ins listed in adapt.json.)

• If GMCQ has been uninstalled from the Adapt authoring tool, it may be reinstalled using the Plug-in Manager.

Settings Overview

The attributes listed below are used in components.json to configure GMCQ, and are properly formatted as JSON in example.json. Visit the GMCQ wiki for more information about how they appear in the authoring tool.

Attributes

In addition to the attributes specifically listed below, question components can implement the following sets of attributes:

• core model attributes: These are inherited by every Adapt component. They have no default values. Like the attributes below, their values are assigned in components.json.
• core buttons: Default values are found in course.json, but may be overridden by GMCQ's model in components.json.

_component (string): This value must be: gmcq.

_classes (string): CSS class name to be applied to GMCQ’s containing div. The class must be predefined in one of the Less files. Separate multiple classes with a space.

_layout (string): This defines the horizontal position of the component in the block. Acceptable values are full, left or right.

instruction (string): This optional text appears above the component. It is frequently used to guide the learner’s interaction with the component.

_attempts (integer): This specifies the number of times a learner is allowed to submit an answer. The default is 1.

_shouldDisplayAttempts (boolean): Determines whether or not the text set in remainingAttemptText and remainingAttemptsText will be displayed. These two attributes are part of the core buttons attribute group. The default is false.

_isRandom (boolean): Setting this value to true will cause the _items to appear in a random order each time the component is loaded. The default is false.

_questionWeight (number): A number which reflects the significance of the question in relation to the other questions in the course. This number is used in calculations of the final score reported to the LMS.

_selectable (number): Defines the number of _items, or answers, that can be selected. If the value of _selectable is 1, _items will be presented with HTML radio buttons. If the value is greater than 1, they will be presented with HTML checkboxes. This number must match the number of _items whose _shouldBeSelected is set to true. The default is 1.

_recordInteraction (boolean) Determines whether or not the user's answers will be recorded to the LMS via cmi.interactions. Default is true. For further information, see the entry for _shouldRecordInteractions in the README for adapt-contrib-spoor.

_items (array): Each item represents one choice for the multiple choice question and contains values for _graphic, text, and _shouldBeSelected.

text (string): Optional text that is displayed as part of the multiple choice option.

_shouldBeSelected (boolean): Value can be true or false. Use true for items that must be selected for a correct answer. The value of _selectable must correspond to the number of _items where _shouldBeSelected is set to true.

feedback (string): This attribute is used only when the value for _selectable is set to 1 (i.e., radio button style questions). This text will be shown if the learner selects this item, and it is an incorrect answer.

_graphic (object): The image that appears as a possible answer. It contains values for large, small, alt, and title.

large (string): File name (including path) of the image used with large device width. Path should be relative to the src folder (e.g., course/en/images/origami-menu-two.jpg).

small (string): File name (including path) of the image used with small device width. Path should be relative to the src folder (e.g., course/en/images/origami-menu-two.jpg).

alt (string): This text becomes the image’s alt attribute.

_feedback (object): If the Tutor extension is enabled, these various texts will be displayed depending on the submitted answer. _feedback contains values for three types of answers: correct, _incorrect, and _partlyCorrect. Some attributes are optional. If they are not supplied, the default that is noted below will be used.

correct (string): Text that will be displayed when the submitted answer is correct.

_incorrect (object): Texts that will be displayed when the submitted answer is incorrect. It contains values that are displayed under differing conditions: final and notFinal.

final (string): Text that will be displayed when the submitted answer is incorrect and no more attempts are permitted.

notFinal (string): Text that will be displayed when the submitted answer is incorrect while more attempts are permitted. This is optional—if you do not supply it, the _incorrect.final feedback will be shown instead.

_partlyCorrect (object): Texts that will be displayed when the submitted answer is partially correct. It contains values that are displayed under differing conditions: final and notFinal.

final (string): Text that will be displayed when the submitted answer is partly correct and no more attempts are permitted. This is optional—if you do not supply it, the _incorrect.final feedback will be shown instead.

notFinal (string): Text that will be displayed when the submitted answer is partly correct while more attempts are permitted. This is optional—if you do not supply it, the _incorrect.notFinal feedback will be shown instead.

Accessibility

Graphical Multiple Choice Question has been assigned a label using the aria-label attribute: ariaRegion. This label is not a visible element. It is utilized by assistive technology such as screen readers. Should the region's text need to be customised, it can be found within the globals object in properties.schema.
