Initialization

This article details the properties that are passed as parameters to the window.LearnosityItems.init() method to initialize Items API.

This method is the starting point to initializing and rendering Items API, and as you can see in the example below, takes two key parameters.

Only the Initialization object is mandatory. Further detail on getting started and initializing Items API can also be found in the Getting Started guide.

Initialization Object

The Initialization object is a JSON object which is passed as the first parameter into the window.LearnosityItems.init() method. It includes all the information needed to initialize the API.

It contains the following two top-level properties:

The Security object is a property generated by the Learnosity serverside SDKs to ensure that any of the APIs are only initialized from a secured, allowed source, using your consumer key and secret.

Default: false
skip_highlight_animation Deprecated
Type: boolean

This property skip_highlight_animation is superseded by skip_replay_animation which can be used for general usage to skip animations for all question types. Please refer to and use skip_replay_animation.

Default: false
skip_replay_animation
Type: boolean

Causes replay animations to be skipped for all Question types, when set to true.

If this property is enabled in the "review" state, Question types that support replay animations won't show the replay animation (such as image highlight and drawing Question types).

The property skip_replay_animation will be considered true if either skip_replay_animation or skip_highlight_animation is set to true.

This property supersedes the skip_highlight_animation property, which has been deprecated.

Default: false
validateOnSubmit
Type: boolean

If enabled, Items API will determine whether instant feedback should be provided when the users submit their assessment.

Not all questions support this feature. Incompatible questions will be ignored.

Note When enabled, all supported questions will be validated regardless of the setting of instant_feedback inside each question.

Important Each question may define its own maximum number of validation attempts through feedback_attempts. Once reached, the question will not be validated again.

Important Supported with rendering_type: "inline" only.

Default: false
question_source
Type: string

If set, Questions API will attempt to render questions using saved data within the Learnosity database, instead of the values passed in the questions array.

Note This behavior only affect activities initializing in "resume" or "review" states.

Possible values:
  • "original" retrieves the Question JSON captured on init. This is always the original Question as seen by the student.
  • "scorable" retrieves the version of the Question currently used for backend scoring. Unless modified via the rescoring process, this will be the same as the original Question seen by the student.
  • "raw" uses the latest/raw JSON definitions loaded by Items API from the Itembank.
Default: raw
object
Used to define time parameters including countdown and expiry settings.

Important Supported with rendering_type: "assess" only.

Properties:
countdown
Type: number
Count down time in seconds shown to the student in a modal window, if an administrator ends their session via remote control.
Default: 10
countdown_option
Type: boolean
By default, the timer in the player counts up from zero. Setting this option to true will enable the timer to count down from max_time.
Default: false
limit_type
Type: string
Specify the action when the time limit (max_time) expires. A hard limit forces a dialog for the student to submit the test, a soft limit has no action.
Possible values:
  • "soft"
  • "hard"
Default: "soft"
max_time
Type: number
The length of test session, in seconds.
Default: 1500
warning_time
Type: number
If set, the assessment player will show a visual cue (red background) in the timer element when the session has warning_time seconds left.
 
"time": {
    "max_time": 600,
    "limit_type": "hard",
    "warning_time": 60,
    "countdown_option": true
}
object

The properties inside this object are used to configure options relating to Dynamic Content, a form of smart content which allows many variations of the same Question.

See What is Dynamic Content? for more information.

Properties:
data_table_seed
Type: string

A randomising seed that will be used to generate a sequence of data rows given to students clicking Try Again.

Default: If not defined, the random seed will use the value of the current session_id.
try_again
Type: object

Allows students to ask for another set of data for the Question they are attempting.

 
"dynamic_items": {
    "data_table_seed": "SOME_SEED",
    "try_again": {
        "max_attempts": 5,
        "random": true
    }
}
object

Allows students to ask for another set of data for the Question they are attempting.

Properties:
max_attempts
Type: integer

A number from 1 to 10 that sets the amount of times the user can click Try Again. Dataset rows are processed sequentially by default.

Default: If the number of dataset rows is less than the defined max_attempts, then that Item will will use the number of rows available.
random
Type: boolean

Changes the initial loading of data rows from the original author dataset to be random (when true). This controls how the data from the dataset is captured and brought down to the page.

Default: false
boolean

Loads the Events API within the Assessment enabling publishing of custom events for advanced use-cases.

Note Events API must be enabled on your consumer for this to work.

See Events API item.publishEvent() for more information.

Default: false
string
Sets the default Item Pool to retrieve content (Activity template and Items) from.

See Data API Pools for more information.

Array[string | ItemObject]

Sets the content to be shown in the session. Can be an array of unique string Item references, or an array of Item objects for advanced usage.

Important This is a mandatory property unless adaptive or sections are configured, or using an activity_template_id with items in it.

Types
string
ItemObject

Item objects can be used in place of Item references when Items from multiple Item banks or Item pools need to be used within the same Activity.
string

Name of the activity that will be displayed in Learnosity's Reports API and Data API.

Important Required only if submitting responses to Learnosity.

string
Sets the default Item Bank to retrieve content (Activity template and Items) from.

See Multiple Activity template and Item sources for more information.

string
The rendering type dictates whether the activity will be rendered using the Learnosity's assessment player, or Items embedded in multiple different locations.
Possible values:
  • "assess"
  • "inline"
boolean
Brings the Item tags along with the assessment content. Used for content debugging in test environments or other advanced use-cases.
Default: false
string
Override the scoring type of the items loaded from the Item Bank (unless otherwise overridden per item, which takes precedence).

See Item Scoring tutorial for more information.

array[object]

Sections allow split a single activity into discrete buckets of items, with the ability to have different title and subtitle per section.

Important Once students progress to a new section, they cannot navigate back.

Properties:
config
Type: array[object]
You can override initial configuration by passing properties such as:
  • regions e.g. allowing assessments to be broken up into sections for delivery, with some sections having specific tools (e.g. calculator) and others without tools.
  • title
  • subtitle
items
Type: array[object]
This works exactly like items in a normal activity.

See items definition for more information.

string

This ID is used to uniquely identify the users assessment session.

Important Must be a valid UUID Version 4. e.g: f47ac10b-58cc-4372-a567-0e02b2c3d479

object

Custom metadata to include for the user's assessment session. This metadata is stored when the session is saved or submitted.

string

Sets the state of the activity.

Since version v1.76 of Items API, for submit_practice type, Items API always checks if the session exists to decide if state should be initial or resume and adjusts it accordingly. This means you only need to set it when wanting to initialize with review state.

Possible values:
  • "initial"
  • "resume"
  • "review"
Default: "initial"
array
Subscores are a breakdown of a total score achieved for an activity. They allow you to extract groups of Items, and focus on scoring them separately.

See Activity Subscores for more information.

string
Defines the session context, including whether student responses are to be submitted and stored or remain available locally only.
Possible values:
  • "local_practice" - assessment is rendered, but the responses will not be stored in Learnosity's servers
  • "submit_practice" - assessment is rendered and responses are stored in Learnosity's servers, allowing for grading and review of the session
  • "feedback" - the assessment is aimed at capturing teacher's feedback. More information
Default: "submit_practice"
string
The ID of the user that is attempting the assessment. Should not exceed 50 characters, nor contain any personally identifiable information. Recommended to be a UUID.

The Callbacks object contains optional callback functions that allow detection of the ready status of an Items API instance and any errors encountered.

An example of how to construct this object can be seen above.

The readyListener callback in particular is very important for the correct functioning of Items API. Most of the methods provided by the returned object from window.LearnosityItems.init() will not be fully available until after the readyListener callback has triggered.

Properties

Function to be called on a Learnosity error event. Receives an Error object.

See troubleshooting for more information.

Parameters
error
Type: Error
Function to be called when the API has been successfully initialized.

In the Initialization object and Callback sections above, there are some object definitions which are complex enough to document separately. These are listed below, and linked from the relevant documentation above.
