adapt-contrib-assessment

Assessment is an extension bundled with the Adapt framework.
It is not a single question component. It is an extension that provides a score for all the question components contained within a single article and that communicates the score to the LMS if so configured. It does not display results. Results are presented with the Assessment Results component (for the results from a single assessment) or the Assessment Results Total component (for the results from multiple assessments).

Important:
The Assessment extension applies to the entire article. Since _randomisation may reorder blocks within the article, it is highly recommended to include only question components within the assessment article. The Results component should be placed in a separate article, not within the assessment article.

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

##Installation

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

• If Assessment 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-assessment

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

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

Settings Overview

Assessment is configured with the attributes that follow. It is configured on three levels of the content structure: course (course.json), article (articles.json), and block (blocks.json). The attributes are so grouped below and are properly formatted as JSON in example.json. Visit the Assessment wiki for more information about how they appear in the authoring tool.

Attributes

course.json

The following attributes, set within course.json, configure the defaults for all assessments in the course. These attributes can be overridden on a per assessment basis by setting attributes of the same names in articles.json.

_assessment (object): The Assessment object that contains values for _scoreToPass, _isPercentageBased, _postTotalScoreToLms, and _requireAssessmentPassed.

_scoreToPass (integer): This is the achievement score required to pass the assessment. The learner's score must be greater than or equal to this score. It is the cumulative raw score needed to pass unless _isPercentageBased is set to true.

_isPercentageBased (boolean): Determines whether the value of _scoreToPass should be treated as a percentage or as the raw score. For example, if _isPercentageBased is set to true, a _scoreToPass value of 60 will be treated as 60%.

_postTotalScoreToLms (boolean): Specifies whether the total score (as a percentage) should be sent to the LMS. Acceptable values are true or false.

_requireAssessmentPassed (boolean): Determines if a pass is required for each assessment to be completed.

articles.json

The following attributes are appended to a particular article within articles.json. Multiple assessments may be used within a course, but they must be configured in separate articles.

_assessment (object): The Assessment object that contains values for _isEnabled, _id, _isPercentageBased, _scoreToPass, _banks, _randomisation, _questions, _includeInTotalScore, _assessmentWeight, _isResetOnRevisit, and _attempts.

_isEnabled (boolean): Turns the assessment on or off. Acceptable values are true or false.

_id (string): This is a unique name for the assessment. This value is used by other plug-ins, such as adapt-contrib-assessmentResults, to identify the assessment and to display its variables.

_isPercentageBased (boolean): Determines whether the value of _scoreToPass should be treated as a percentage or as the raw score. For example, if _isPercentageBased is set to true, a _scoreToPass value of 60 will be treated as 60%.

_scoreToPass (number): This is the achievement score required to pass the assessment. The learner's score must be greater than or equal to this score. It is the cumulative raw score needed to pass unless _isPercentageBased is set to true.

_includeInTotalScore (boolean): Determines if the score from this assessment should be sent to the LMS. The score sent is a percentage according to _assessmentWeight.

_banks (object): If _banks is enabled, its attributes determine which questions from a series of question banks/buckets will be presented to the learner. Contains values for _isEnabled, _split, and _randomisation. (Use either _banks or _randomisation; the value of their _isEnabled attributes must be opposite booleans. If _banks is enabled, blocks must be organized into questions banks by adding the _quizBankID attribute referenced below.)

_isEnabled (boolean): Turns on or off the ability to use question banks.

_split (string): This is a comma-separated list of numbers corresponding to the number of questions to be drawn from each identified block. The position of the numberal in the list corresponds to the _quizBankID assigned to a block. The value of the number determines how many questions to retrieve randomly from that particular quiz bank. For example, a _split with a value of "2,1" would pick 2 questions from bank 1 ("_quizBankID": "1") and 1 question from bank 2 ("_quizBankID": "2").

_randomisation (boolean): Determines whether the questions will be displayed in the same order as the blocks are ordered in blocks.json or will be shuffled before they are presented to the learner. Acceptable values are true or false.

_randomisation (object): If _randomisation is enabled, its attributes control how many random questions will be presented to the learner. Contains values for _isEnabled and _blockCount. Questions and the order in which they are presented are maintained throughout an attempt, should a learner leave the assessment incomplete and return later. (Use either _randomisation or _banks; the value of their _isEnabled attributes must be opposite booleans.)

_isEnabled (boolean): Turns on or off the ability to use _randomisation.

_blockCount (number): The number of blocks to present to the learner. (Questions are presented by blocks. If one component occupies a block, it will be presented alone. If multiple components occupy a block, they will always appear together.)

_questions (object): Contains attributes for overriding question component behaviours. Contains values for _resetType, _canShowFeedback and _canShowMarking.

_resetType (string): Determines whether the question component will register as completed when reset. When assigned a value of soft, the learner may continue to interact with it, but the component's _isComplete attribute remains set to true. When assigned hard, _isComplete is set to false, and the learner will be forced to complete it again if it is reset. Other plug-ins, such as Page Level Progress and Trickle, base their behavior on the value of a component's _isComplete attribute. Acceptable values are hard or soft.

_canShowFeedback (boolean): Determines whether a question component within the assessment will be permitted to show its feedback. Acceptable values are true or false.

_canShowMarking (boolean): Determines whether a question component within the assessment will show the marking after the user has answered. Acceptable values are true or false.

_assessmentWeight (number): If there are multiple assessments in the course, this value controls the proportion of the LMS score which is attributed to this assessment. 1 = 100%.

_isResetOnRevisit (boolean): Controls whether the assessment should be reset automatically (up to the number of available attempts) when a user revisits the page. Acceptable values are true or false.

_attempts (number): Controls the number of attempts available to the user. Any of the following values may be used to indicate an infinite number of attempts: -1, 0, null, undefined, "infinite".

blocks.json

_assessment (object): The Assessment object that contains a value for _quizBankID.

_quizBankID (string): Add the _quizBankID attribute to your assessment blocks in order to organize them into question banks/buckets. IDs are coordinated with positions in the _split attribute. Quiz bank IDs are a 1-based index. The first position in the list corresponds to "_quizBankID": 1, the second position corresponds to "_quizBankID": 2, and so on. A value of '2,1' in _split would pick 2 questions from "_quizBankID": 1 and one question from "_quizBankID": 2.

Limitations

Assessment must be used with question components that extend and implement Adapt's questionView. If data is required to be passed to a SCORM conformant LMS, the Spoor extension must be enabled. If question components are required to display feedback after attempts, the Tutor extension must be enabled. And if it is appropriate to display performance results to the learner, a separate component such as Assessment Results is required.
