Student Events#

This section lists events that are typically initiated by learners. These events are generated by interactions with the learning management system (LMS) other than the instructor dashboard.

For a list of events generated by course team interactions on the instructor dashboard, see Course Team Events. For a complete, alphabetical list of events, see the Alphabetical Tracking Log Event List.

The descriptions that follow include what each event represents, the system component it originates from, the history of any changes made to the event over time, and member fields in addition to the common context or event fields.

The value in the event_source field distinguishes between events that originate in the browser (in JavaScript) and events that originate on the server (during the processing of a request).

For more information about the common context or event fields, and about the event_source field, see Common Fields.

Bookmark Events#

Bookmark events are described in Course Resource Events.

Certificate Events#

This section includes descriptions of the events related to certificates, which are awarded to qualified learners when they complete a course.

edx.certificate.created#

When a certificate is generated, a record is created in the certificates_generatedcertificate table, triggering an edx.certificate.created event.

It may be important to note that it is possible for this event to be fired when an existing certificate record in the certificates_generatedcertificate table is updated. For example, if a certificate was revoked from a learner due to them no longer passing the course, and then they earned a passing grade at a later time, an edx.certificate.created event will be fired again (even though the record for this learner already exists in the database).

Cohort Events (Student)#

This section includes descriptions of the following events.

edx.cohort.created#

When a course team or the system creates a cohort, the server emits an edx.cohort.created event. Cohorts can be created manually by members of the course team. The system automatically creates the default cohort and any cohorts that are defined by the auto_cohort_groups advanced setting when they are needed (for example, when a student is assigned to one of those cohorts).

Additional events are emitted when members of the course team select Instructor in the LMS to create a cohort on the instructor dashboard. See Cohort Events (Course Team).

The display name of the cohort.

edx.cohort.user_added#

When a user is added to a cohort, the server emits an edx.cohort.user_added event. Members of the course team can add users to cohorts individually or by uploading a .csv file of student cohort assignments. The system automatically adds a user to the default cohort or a cohort included in the course’s auto_cohort_groups setting if a user who has not yet been assigned to a cohort accesses course content.

Additional events are emitted when members of the course team select Instructor in the LMS to add a user to a cohort on the instructor dashboard. See Cohort Events (Course Team).

Course Content Completion Event#

This section describes the event emitted by the completion XBlock, which adds a toggle control in course content. This toggle allows learners to mark the associated section of course content as complete.

EdX recommends using the completion XBlock primarily for progress tracking of ungraded activities, such as reading assigned texts, watching videos, or participating in course discussions.

Learners are not limited in the number of times that they can toggle the control between the default incomplete state and the completed state.

History: Added 27 Jan 2016.

edx.done.toggled#

Both the browser and the server emit the edx.done.toggled event when the control added by the Completion XBlock is toggled. The event_source field indicates whether the event was emitted by the client or the server.

event Member Fields:

Field

Type

Details

done

Boolean

Indicates the state of the Completion toggle at the time the event is emitted. Possible values are true (a learner has completed the associated content) and false (a learner has not completed the associated content).

Content Library Interaction Events#

This section includes descriptions of the following events.

Course teams in an organization can collaboratively contribute to content libraries, such as a collection of problem components for a particular subject. Content libraries are created and maintained separately from courses so that their content can be used in different courses.

In a course outline, course teams can include randomized content block components that reference a content library and deliver its content to students. In a randomized content block component, the course team defines the type and number of content library components to deliver to each student.

edx.librarycontentblock.content.assigned#

The server emits an edx.librarycontentblock.content.assigned event the first time that content from a randomized content block is delivered to a user. The edx.librarycontentblock.content.assigned event identifies the components delivered from the library to a user.

Additional edx.librarycontentblock.content.assigned events can also be emitted if the course team makes a change that results in an increase in the number of components that the randomized content block delivers. After such a change, the randomized content block delivers more components to any user who revisits it after that change. For those users, the edx.librarycontentblock.content.assigned event identifies the complete set of components delivered from the library and also the components that were delivered for the first time.

History: Added 18 Mar 2015.

Event Source: Server

event Member Fields:

Field

Type

Details

added

list

Lists the library components that were delivered to the user for the first time. The content of this field is different from the content of the result field only if the user revisited the randomized content block and it delivered additional components from the library.

location

string

Identifies the randomized content block component.

max_count

number

The Count specified by a course team member in Studio. Defines the number of library components to deliver. This number is greater than the number of library components listed by the result field only when the library has too few matching blocks available.

previous_count

number

The number of components assigned to this student before this event. The first time the user views the randomized content block, this value is 0.

result

list

Lists all of the library components delivered to the user.

  • descendants, when present, is a list that identifies each part of a library component that contains multiple parts (the children of an XBlock with children).

  • original_usage_key and original_usage_version identify the component in the library.

    When students attempt a problem component delivered by a randomized content block, the resulting problem events also reference the original_usage_key and original_usage_version in context.module member fields. See context Field.

  • usage_key identifies the location of this component in the course. This value identifies a child of the randomized content block component.

To identify a component consistently within a course, you can use either usage_key or original_usage_key as a consistent identifier. To identify components across courses, use orignal_usage_key.

edx.librarycontentblock.content.removed#

The server emits an edx.librarycontentblock.content.removed event when a user revisits a randomized content block and one or more of the components that were previously delivered to that user can no longer be delivered.

  • If components are removed from the library and the course team resynchronizes the randomized content block to the library, the server emits an edx.librarycontentblock.content.removed event if a user who was previously assigned one of those components revisits the randomized content block or accesses the progress page.

  • If the course team changes settings for the randomized content block so that fewer or different components are allowed.

    For example, the course team reduces the number of library components to deliver or specifies a different type of problem to deliver.

History: Added 18 Mar 2015.

Event Source: Server

event Member Fields:

The edx.librarycontentblock.content.removed events include the following event member fields. These fields serve the same purpose for events of this type as for the edx.librarycontentblock.content.assigned events.

        }
}

edx.ui.lms.sequence.next_selected#

The browser emits this event when a user selects the “next” control in the unit navigation bar in the LMS. Users can use the “next” control to navigate from one unit to the next unit within the current subsection, or from the last unit in one subsection to the first unit in the next subsection.

History: On May 3, 2016, the “next” navigation control in the LMS was enhanced to allow users to move not only within a subsection but also between subsections. The seq_next event was correspondingly enhanced with additional fields and now maps to the new event edx.ui.lms.sequence.next_selected. Before May 3, 2016, the name and event fields for the seq_next event were both set to the same value. Events that have both a name and an event_type of seq_next are no longer emitted.

The new event with a name value of edx.ui.lms.sequence.next_selected is emitted when users navigate in the LMS using the “next” control. Depending on whether a learner navigates within the current subsection or between subsections, the resulting event has a different event_type value.

  • Navigating to the next unit within a subsection (the already supported interaction that previously emitted the seq_next event) now emits the new event with an event_type of seq_next, so that you can continue to track the same interaction.

  • Navigating from the last unit in one subsection to the first unit in the next subsection, which is the newly supported interaction, emits the new event with both an event_type and name of edx.ui.lms.sequence.next_selected.

Component: Sequence

Field

Type

Details

current_tab

integer

Identifies the tab or icon in the unit navigation bar that the user was viewing prior to selecting “next”. Tabs correspond to the unit in the subsection (or verticals in the sequence) and are indexed starting from 1. If this value is equal to tab_count, the user was on the last vertical of the subsection.

id

string

The usage key of the subsection that is being navigated by the user.

new

integer

Identifies the tab that the user was navigating to.

This field is included only for events that are emitted by “next” navigation within a subsection. These events have an event_type of seq_next to enable backward compatibility with the seq_next events emitted prior to 3 May 2016.

old

integer

Identifies the tab that the user was navigating from.

This field is included only for events that are emitted by “next” navigation within a subsection. These events have an event_type of seq_next to enable backward compatibility with the seq_next events emitted prior to 3 May 2016.

The edx.ui.lms.sequence.next_selected events emitted after 3 May 2016 use the current_tab value to identify the user’s position in the unit, and do not include this field.

tab_count

integer

The number of tabs in the unit navigation bar. This number matches the total number of units in the current subsection.

widget_placement

string

Unit navigation controls appear at the top and bottom of pages in the LMS. Values for this field can be “top” or “bottom”, indicating the position on the page of the control that the user selected.

Example edx.ui.lms.sequence.next_selected Events#

The following example shows the relevant fields in the event that is emitted when a user navigates within the same subsection using the “next” control.

        }
}

edx.ui.lms.sequence.previous_selected#

The browser emits this event when a user selects the “previous” control in the unit navigation bar in the LMS. Users can use the “previous” control to navigate from one unit back to the previous unit within the current subsection, or from the first unit in one subsection to the last unit in the previous subsection.

History: On May 3, 2016, the “previous” navigation control in the LMS was enhanced to allow users to move not only within a subsection but also between subsections. The seq_prev event was correspondingly enhanced with additional fields and now maps to the new event edx.ui.lms.sequence.previous_selected. Before May 3 2016, the name and event fields for the seq_prev event were both set to the same value. Events that have both a name and an event_type of seq_prev are no longer emitted.

After May 3 2016, an event that has a name value of edx.ui.lms.sequence.previous_selected is emitted when users navigate in the LMS using the “previous” control. Depending on whether a learner navigates within the current subsection or between subsections, the resulting event has a different event_type value.

  • Navigating to the previous unit within a subsection (the already supported interaction that previously emitted the seq_prev event) now emits the new event with an event_type of seq_prev, so that you can continue to track the same interaction.

edx.ui.lms.sequence.tab_selected#

The browser emits this event when a user selects any tab in the unit navigation bar in the LMS to navigate to another unit within the subsection. Tabs correspond to the unit in the subsection (or verticals in the sequence).

History: On May 3, 2016, the seq_goto event was promoted to a new naming infrastructure and now maps to the new event edx.ui.lms.sequence.tab_selected. Before May 3, 2016, the name and event fields for the seq_goto event were both set to the same value.

New fields have been added to the event, but existing fields are retained for backward compatibility. The updated event has a name value of edx.ui.lms.sequence.tab_selected and an event_type value of seq_goto, to ensure that you can map these new events to the seq_goto events that were emitted previously.

Discussion Forum Events#

This section includes descriptions of the following events.

The server emits discussion forum events when a user interacts with a course discussion. This section presents the discussion forum events alphabetically. However, several of these events have hierarchical or sequential relationships.

  • When a user creates a new thread, such as a student asking a question, the server emits an edx.forum.thread.created event.

  • When a user responds to a thread, such as another student answering the question, the server emits an edx.forum.response.created event.

  • When a user adds a comment to a response, such as a course team member adding a clarification to the student answer, the server emits an edx.forum.comment.created event.

These events are emitted and included in daily event logs in addition to the MongoDB discussion forums database data that is included in the weekly database data files.

If a thread, response, or comment was part of a team discussion within a course, a team_id field is also included in events for creation or voting interactions. The team_id identifies the team that triggered the discussion event. For more information about events for teams, see Teams-Related Events.

Testing Events for Content Experiments#

This section includes descriptions of the following events.

Course authors can configure course content to present modules that contain other modules. Content experiments, also known as A/B or split tests, use this structure. For example, a parent module can include two child modules that contain content that differs in some way for comparison testing.

  • Internally, a partition defines the type of experiment: comparing the effectiveness of video alone to text alone, for example. A course can include any number of modules that have the same partition or experiment type.

  • For each partition, students are randomly assigned to a group. The group determines which content, either video or text in this example, is shown by every module with that partitioning.

  • Students are assigned to groups randomly. Assignment to a group takes place when student navigation through the course requires data from that module. For example, one student is assigned to a group when he visits the course progress page, while another student is assigned to a group when she visits a course component that is the parent module of a content experiment. Based on this random group assignment, the content of just one of the two child modules is shown to the student.

  • For investigations into which students in each group actually interacted with tested content, review the events for the behavior you want to learn about. For example, review the students’ play_video , textbook.pdf.page.navigated, or problem_check events.

The events that follow apply to modules that are set up to randomly assign students to groups so that different content can be shown to the different groups.

History: These events were added on 12 Mar 2014.

xmodule.partitions.assigned_user_to_partition#

When a student views a module that is set up to test different child modules, the server checks the user_api_usercoursetag table for the student’s assignment to the relevant partition, and to a group for that partition.

  • The partition ID is the user_api_usercoursetag.key.

  • The group ID is the user_api_usercoursetag.value.

If the student does not yet have an assignment, the server emits an xmodule.partitions.assigned_user_to_partition event and adds a row to the user_api_usercoursetag table for the student.

Note

After this event is emitted, the common context field in all subsequent events includes a course_user_tags member field with the student’s assigned partition and group.

Timed Exam and Proctored Exam Events#

Special exams are a type of course exam that includes timed exams, proctored exams, and practice proctored exams. These exam types offer more complicated functionality than other assignment types in graded subsections, and they emit additional events. Special exam events provide information about special exams included in courses and learners’ interactions with those special exams.

  • Proctored exams have a time limit and they require learners to install and run monitoring software while taking the exam. After a learner completes a proctored exam, a team of reviewers determines whether the learner complied with all of the exam rules based on records generated by the monitoring software.

  • Practice proctored exams allow learners to become familiar with the monitoring software that they will use during an actual proctored exam. The way that a learner experiences a practice proctored exam is identical to a proctored exam. In a practice proctored exam, the monitoring software does not send exam records to reviewers.

  • Timed exams have a time limit. Learners do not install or use monitoring software when they take a timed exam.

Practice proctored exams follow a workflow that is similar to proctored exams but do not include a review of the exam attempt. Timed exams also follow a similar workflow but do not include any proctoring software or review of the exam attempt.

The following diagram shows the workflow for a proctored exam.

A diagram showing the workflow for a proctored exam.

Some special exam events are emitted when course teams develop and administer exams. For more information, see Timed and Proctored Exam Development and Administration Events.

Because special exams include similar functions and behavior, they share some similar events. For example, the edx.special_exam.proctored.allowance.created, edx.special_exam.practice.allowance.created, and edx.special_exam.timed.allowance.created events include identical fields.

This section includes descriptions of the following events.

Video Interaction Events#

This section includes descriptions of the following events. Due to a naming convention change, many of these events have two identifying names. In this list, the original name, which is present in the event_type field for all events, is followed by a newer, revised name. The revised name is present in the name field only for events that have an event_source of ‘mobile’.

A browser or the edX mobile app emits video interaction events when a user interacts with a video.

  • When users use a browser to stream video files on a desktop computer or mobile device, the browser emits the events.

  • When users use the edX mobile app to stream or download course videos for offline viewing, the mobile app emits the events.

    When a user interacts with a downloaded video file offline using the edX mobile app, note that the app can only forward its events during the next connection opportunity. As a result, the date and time in the event’s time field can be different from the date and time in its context.received_at field. Data packages can include events emitted on past dates.

This section presents the video interaction events alphabetically. Typically, an interaction with the video player begins with a play_video/edx.video.played event.

For courses that include a pre-roll video, user interactions with the pre-roll video result in different events. For more information, see Pre-Roll Video Interaction Events.

History: The edX mobile app for iOS began to emit a subset of the video events on 25 Feb 2015. The edX mobile app for Android began to emit a subset of the video events on 23 Dec 2014.

pause_video/edx.video.paused#

When a user selects the video player’s pause control, the player emits a pause_video event. For videos that are streamed in a browser, when the player reaches the end of the video file and play automatically stops it emits both this event and a stop_video event (as of June 2014).

Note that course teams can specify a Video Stop Time for video files.

  • If the user streams a video file in a browser and a Video Stop Time is present for the video, the player stops at the specified time and emits the pause_video and stop_video events.

  • If the user plays a streaming or downloaded video in the edX mobile app, the app ignores the Video Stop Time and plays the file to its end. The app then emits only the stop_video event.

In addition to the identifying event_type of pause_video, the events that the edX mobile app emits include a name field with a value of edx.video.paused.

History:

  • Updated 5 May 2015 to include the effect of a Video Stop Time.

play_video/edx.video.played#

When a user selects the video player’s play control, the player emits a play_video event.

Note that course teams can specify a Video Start Time for video files.

  • If the user streams a video file in a browser and a Video Start Time is present for the video, the player starts at the specified time and emits the play_video event.

  • If the user plays a streaming or downloaded video in the edX mobile app, the app ignores the Video Start Time and emits the play_video event when it plays the file from the beginning.

In addition to the identifying event_type of play_video, events that the edX mobile app emits also include a name field with a value of edx.video.played.

History:

  • Updated 5 May 2015 to include the effect of a Video Start Time.

seek_video/edx.video.position.changed#

A browser emits seek_video events when a user selects a user interface control to go to a different point in the video file.

  • On a desktop computer, users can click and drag in the playback bar or click in a transcript to change position.

  • In the edX mobile app, users can click and drag in the playback bar or tap the “back 30 seconds” button to change position.

  • When using a browser on a mobile device, users can click and drag in the playback bar to change position.

In addition to the value seek_video in the event_type field, the events that the edX mobile app emits include the value edx.video.position.changed in the name field.

History:

  • Updated 10 Mar 2015 to include the final implementation for events emitted by the edX mobile app for Android and iOS. Prototype events were emitted by the mobile app in February and March 2015.

  • Prior to 25 Jun 2014, the old_time and new_time fields were set to the same value.

Event Source: Browser or Mobile

context Member Fields:

Only video interaction events with an event_source of ‘mobile’ include additional context member fields in addition to the common member fields. The same set of additional context fields are added for seek_video/ edx.video.position.changed events as for play_video/edx.video.played. For an example of an event with these fields, see Example: Mobile App-Emitted edx.video.played Event.

event Member Fields:

The seek_video/edx.video.position.changed events include the following event member fields. These fields serve the same purpose for events of this type as for the play_video/edx.video.played events.

  • code

  • id

The following additional event member fields apply specifically to seek_video/edx.video.position.changed events.

Field

Type

Details

new_time

number

old_time

number

The time in the video, in seconds, at which the user chose to go to a different point in the file.

requested_skip_interval

number

Applies only to events with an event_source of ‘mobile’. The number of seconds that the user moved backward (expressed as a negative) or forward in the file.

History: Added 10 Mar 2015.

type

string

The navigational method used to change position within the video.

In events for a user of a desktop computer, this value can be ‘onCaptionSeek’ or ‘onSlideSeek’. In events for a user of the mobile app, this value can be ‘onSlideSeek’ or ‘onSkipSeek’.

show_transcript/edx.video.transcript.shown#

When a user toggles Show Transcript to display the video transcript, the browser or mobile app emits a show_transcript event.

In addition to the identifying event_type of show_transcript, events that the edX mobile app emits also include a name field with a value of edx.video.transcript.shown.

History: Updated 25 Feb 2015 to include events emitted by the edX mobile app for iOS. Updated 23 Dec 2014 to include events emitted by the edX mobile app for Android.

Event Source: Browser or Mobile

context Member Fields:

Only video interaction events with an event_source of ‘mobile’ include additional context member fields in addition to the common member fields. The same set of additional context fields are added for show_transcript/ edx.video.transcript.shown events as for play_video/edx.video.played. For an example of an event with these fields, see Example: Mobile App-Emitted edx.video.played Event.

event Member Fields:

The show_transcript/edx.video.transcript.shown events include the following event member fields. These fields serve the same purpose for events of this type as for the play_video/edx.video.played events.

  • code

  • currentTime: The point in the video file at which the transcript was opened.

  • id

speed_change_video#

A browser emits speed_change_video events when a user selects a different playing speed for the video.

History: Prior to 12 Feb 2014, this event was emitted when a user selected either the same speed or a different speed.

Event Source: Browser

event Member Fields:

Field

stop_video/edx.video.stopped#

When the video player reaches the end of the video file and play automatically stops, the player emits a stop_video event.

Note that course teams can specify a Video Stop Time for video files.

  • If the user streams a video file in a browser and a Video Stop Time is present for the video, the player stops at the specified time and emits the pause_video and stop_video events.

  • If the user plays a streaming or downloaded video in edX mobile app, the app ignores the Video Stop Time and plays the file to its end. The app then emits the stop_video event.

In addition to the identifying event_type of stop_video, the events that the edX mobile app emits include a name field with a value of edx.video.stopped.

History:

  • Updated 5 May 2015 to include the effect of a Video Stop Time.

  • Updated 25 Feb 2015 to include events emitted by the edX mobile app for iOS.
