Perception is a question component for the Adapt framework.
Images are presented to the learner accompanied by a series of possible 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.
Perception must be manually installed in the adapt framework and authoring tool.
If Perception has been uninstalled from the Adapt authoring tool, it may be reinstalled using the Plug-in Manager.
The attributes listed below are used in components.json to configure Perception, and are properly formatted as JSON in example.json.
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 Perception's model in components.json.
_component (string): This value must be: perception.
_classes (string): CSS class name to be applied to Perception’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.
_canShowModelAnswer (boolean): Setting this to false prevents the _showCorrectAnswer button from being displayed. The default is true.
_canShowFeedback (boolean): Setting this to false disables feedback, so it is not shown to the user. The default is true.
_canShowMarking (boolean): Setting this to false prevents ticks and crosses being displayed on question completion. The default is true.
_recordInteraction (boolean) Determines whether or not the learner'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.
_options (array): Each item represents one choice for the item and contains values for text.
text (string): This text becomes the text on the option button.
_items (array): Each item represents one item for the perception question and contains values for _correctOption, title, body, and _graphic.
_correctOption (number): Determines which option is correct.
title (string): This text becomes the title for the item.
body (string): This text becomes the body text for the item.
_graphic (object): This contains values for _src, and alt.
_src (string): File name (including path) of the image used for the item. Path should be relative to the src folder.
alt (string): This text becomes the image’s
altattribute.
_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.
Perception 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.
