In recent years there has been a disruptive trend toward providing educational courses online. In general, the online courses offered today are provided in video recorded lecture format. In this format, a video recording is made of the lecturer, e.g., standing at a podium or on a stage, or at a chalkboard or whiteboard or on a virtual whiteboard displayed in the video. A student user views the video online, and may be presented with a multiple choice quiz or other type of test to assess their comprehension and mastery of the subject matter. Additional supplemental materials such as a slide deck, text document, hyperlinks to web pages, etc., may also be provided as separate download files.
While offering certain benefits, the present state of online course technologies lacks authoring flexibility for educators, as they generally require use of video editing tools to make any edits, modifications, deletions or additions to a recorded lecture. It is often difficult or even infeasible to insert quizzes, interactive exercises, web-content or linked-videos into the video-flow of lessons. There is also no easy way to obtain comprehensive analytics and statistics from student viewing of such lessons with linked interactive components.
It is with respect to these considerations and others that the disclosure made herein is presented.
Technologies are described herein for authoring, sharing and consumption of interactive online courses (which might also be referred to herein as “lessons”). In particular, an augmented presentation document format is provided for authoring, sharing and consumption of online courses that utilize slides with various objects including video objects and digital ink objects. In one example, the augmented presentation document is authored using a presentation application with a lesson creation extension that provides the additional online course authoring functionality and features described herein. Other content creation applications might also utilize and leverage the concepts presented herein, such as word processing applications, spreadsheet applications, electronic book applications, and others.
In the authoring process, a user, such as an educator, may prepare an augmented presentation document including a sequence of slides with content, such as chart objects, graph objects, photo objects, text objects, animation objects, embedded video objects/audio objects, hyperlink objects, etc. Utilizing various technologies disclosed herein, interactive content, such as quizzes, interactive laboratories (“labs”), and/or other types of content might also be inserted into the augmented presentation document as objects during the authoring process. Quiz objects may assess a student's progress in understanding the lessons. Quiz objects may include true/false questions, multiple choice questions, multiple response questions and/or freeform questions, for example. Interactive lab objects may enhance a student's mastery of the lessons through the utilization of various exercises. The user may create quiz objects and/or interactive lab objects or may be insert previously created objects. The user may also insert quiz objects and/or interactive lab objects from third parties such as KHAN ACADEMY.
The educator author then records a lecture of their presentation of the slides in the augmented presentation document. The lesson creation extension captures audio and video of the educator presenting the slides, and may also capture their writing on the slides in one or more digital ink objects. The lesson creation extension segments the recorded content into objects associated with individual slides of the augmented presentation document. In one example, each video object is the video captured of the educator while discussing the associated slide. The extension also captures the time sequence of the digital ink object, also associated with individual slides.
After recording the presentation, the author can edit the presentation by moving or deleting slides, which also moves or deletes that slide's video object in the overall slide-sequence of the presentation. This allows the author to easily modify the sequence of objects, and delete objects. Additionally, the author can add further slides, record video objects and/or digital ink objects associated with the slides, and then edit the additional slides into the original presentation.
Once the author has completed the creation of the augmented presentation document, the augmented presentation document may be uploaded to a portal system for sharing with other users, such as students. The portal system may provide functionality for searching, rating, and viewing of uploaded lessons. The portal system might also provide functionality for allowing an authorized user, such as an educator, to view statistics regarding the viewing of presentations, individual slides, and/or information regarding the use of quiz objects and interactive lab objects contained within presentations. The portal system might also provide forums and other types of community features for students, educators, and other users to share information regarding the lessons.
The portal system also provides functionality for playback of lessons on virtually any type of client computing device. In this regard, playback might be performed through the same application utilized to create a presentation (e.g. a presentation creation application), through the use of a playback tool implemented as a web browser plugin or in another manner, through a dedicated playback application, or in another manner.
During playback (e.g., for viewing by a student user), the augmented presentation document presents each slide synchronized with any objects, such as the slide's video object. The presentation may also present any digital ink object for that slide in a manner that is synchronized with the video object. The playback tool may display a progress bar with segmentation marks corresponding to a slide sequence. The viewer can select a specific point on the progress bar to commence playback, which will go to the associated slide in the augmented presentation document and start playback of the video object for the slide at the time corresponding to the selected point on the progress bar.
According to one aspect presented herein, a system for publishing is provided for an augmented presentation document. The system includes a processor and a memory coupled to the processor storing computer-executable instructions. The computer-executable instructions execute in the processor from the memory. The system receives the augmented presentation document, which comprises one or more slides. As described above, the slides have one or more objects associated therewith. In one implementation, the system extracts objects from the augmented presentation document and stores the objects by object type. Additionally, the system may retrieve the stored objects in response to receiving a request to present the augmented presentation document. The system may also cause the augmented presentation document to be presented in synchronization with the objects.
According to another aspect, a computer-implemented method is provided for creating an augmented presentation document. In one implementation, the method includes executing a lesson creation extension in a presentation application to create the augmented presentation document comprising one or more slides. The method may further include recording one or more types of content. The method may also segment the content into objects, with each object associated with a slide so that the objects and the slides may be presented in synchronization during playback.
According to yet another aspect, a computer-implemented method is provided for receiving an augmented presentation document with one or more slides. The slides of the augmented presentation document having one or more associated objects. In one implementation, the method includes extracting the objects from the augmented presentation document and storing the objects by object type. The method may also include retrieving the object in response to receiving a request to present the augmented presentation document. The method may also provide causing the augmented presentation document to be presented in synchronization with the objects.
It should be appreciated that the above-described subject matter may also be implemented as a computer-controlled apparatus, a computer process, a computing system, or as an article of manufacture such as a computer-readable medium. These and various other features will be apparent from a reading of the following Detailed Description and a review of the associated drawings.
This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended that this Summary be used to limit the scope of the claimed subject matter. Furthermore, the claimed subject matter is not limited to implementations that solve any or all disadvantages noted in any part of this disclosure.
The following detailed description is directed to technologies for authoring, sharing, consuming, and obtaining feedback analytics for online courses. While the subject matter described herein is presented in the general context of program modules that execute in conjunction with the execution of an operating system and application programs on a computer system, those skilled in the art will recognize that other implementations may be performed in combination with other types of program modules. Generally, program modules include routines, programs, components, data structures, and other types of structures that perform particular tasks or implement particular abstract data types. Moreover, those skilled in the art will appreciate that the subject matter described herein may be practiced with other computer system configurations, including hand-held devices, multiprocessor systems, microprocessor-based or programmable consumer electronics, minicomputers, mainframe computers, and the like.
In the following detailed description, references are made to the accompanying drawings that form a part hereof, and which are shown by way of illustration specific configurations or examples. Referring now to the drawings, in which like numerals represent like elements throughout the several figures, aspects of a computing system and methodology for authoring, sharing, and consuming online courses will be described.
As discussed briefly above, the mechanism described herein utilizes three components in some configurations: 1) an authoring component that extends a presentation application in order to make interactive online lessons easy to create; 2) a lesson player application for students that allows students to learn from such interactive lessons on any device and platform of their choice; and 3) a web portal that allows teachers to publish, share, and manage the lessons they create, and to get analytics for their lessons to determine how they may guide students further.
As discussed further below, the mechanism described herein reduces network bandwidth usage by separately storing objects by object type. The objects of an augmented presentation document can be updated from a central location. The updated objects can be retrieved and rendered during playback. Having objects of the augmented presentation document in a central location increases user efficiency and also reduces network bandwidth usage. Additionally, the augmented presentation document increases user efficiency by leveraging familiarity with existing applications, such as a presentation application to create an online lesson with rich objects including video objects and digital ink objects.
An augmented presentation document (which might also referred to herein as a “lesson”) created utilizing the technologies disclosed herein may be experienced in any web browser on any platform. In one configuration, the lesson appears like a slideshow on the web or a video, but it is much more. At a base level, the viewer is presented the augmented presentation document as a slideshow that has been augmented with teacher narration (e.g. audio-video objects and dynamic inking objects on the slide). The narration works seamlessly with animations and other rich element objects of the slideshow. The student may also experience interactive quizzes that the teacher has inserted as quiz objects into the augmented presentation document to help with mastery of content. The student may also find additional resources, such as video objects from KHAN ACADEMY, seamlessly interleaved with the teacher's lesson to enhance their learning. The student may also find other interactive lab objects, from KHAN ACADEMY or other providers, to enhance and test their knowledge. Students can keep trying new questions until they feel they have achieved mastery. To maximize their understanding and mastery of topics, the lesson player application makes it easy to replay, skip or speed-up any parts of the lesson. All student interactions with the lesson player may be recorded so that information may be collected and analytics may be provided to the teacher to help them personalize and guide student learning.
In order to author such an augmented presentation document, a teacher may start with a slide deck that they already have, or they could create a new slides for the online lesson leveraging the familiar capabilities of their presentation application. They would then download an add-in lesson creation extension for their presentation application that implements some of the functionality disclosed herein. Video objects may be generated using a webcam or other video capture device. Digital ink objects may be generated using a Tablet PC or a stylus digitizer or a mouse, among other options.
Within the lesson creation extension, the teacher has tools to create an augmented presentation document. In some configurations, the teacher may utilize a “record lesson” button to record narration and inking to slides. The audio and video objects are automatically split between slides. The teacher or other author does not have to lecture continuously and can chose to review and redo on a slide granularity.
When the teacher exits the record lesson mode, the audio and video objects and digital ink objects will be presented and clearly associated with the slides. The video objects may be repositioned and resized. The slides may also be reordered to change the video objects in the lesson. New slides can be added to further embellish the lesson. These change may be occur while initially making the lesson or later.
In the lesson creation extension, other buttons may allow the teacher to add screen-recording, quizzes, videos, interactive labs, and web pages. In one implementation, the teacher may add a quiz object by selecting the type of quiz along with the questions, hints, etc. before inserting the quiz object. The questions will then appear at that spot in the augmented presentation document. Similarly, the teacher may insert a KHAN ACADEMY video object in the augmented presentation document by clicking on an add-video button, searching for the desired video object and inserting the video object into the augmented presentation document. Interactive lab objects from KHAN ACADEMY, or another provider, may be added into the augmented presentation document by clicking the add-lab button, searching for and inserting the interactive lab object into the augmented presentation document. These interactive lab objects may be HTML5 JAVASCRIPT websites. Once the teacher is finished adding to the lesson, the augmented presentation document may be published by utilizing a “publish” button to upload the augmented presentation document to a portal system to share with students.
A web portal is also provided that allows a teacher to further manage and share the augmented presentation documents created, and to see the analytics collected that describe how students have been interacting with the augmented presentation documents. In the portal, the teacher can rename the lesson, add a description for the lesson, and perform other functionality. The teacher may share the augmented presentation document with their class or another group of users by simply obtaining a uniform resource locator (“URL” or “hyperlink”) for the lesson and sharing the URL with their class through email or a learning management system. The teacher may share the augmented presentation document with their class or may make the augmented presentation document public.
The portal may also allow the teacher to look at information collected for the lesson as analytics. For example, the teacher may see whether students have watched the assigned lesson, what portions they have watched, and how students have done on the quizzes and labs. This information may provide the teacher with essential information to further guide their students. Additional details regarding these mechanisms, and others, will be provided below with regard to

In the authoring process, a user of the presentation application 102, such as an instructor, prepares a slide presentation of a sequence of slides 108 with conventional slide presentation content, such as chart objects, graph objects, photos, text, embedded video objects 112, embedded audio objects 118, hyperlinks 120, web page objects 114, etc. The hyperlinks 120 may point to other slides in the same lesson. Interactive content, such as quiz objects 116, interactive “lab” objects 122, and other types of content might also be inserted into the slide presentation.
An author, such as an instructor, may record a video narration of their presentation of the slides 108. The lesson creation extension 104 captures a video of the instructor presenting the slides 108, and may also capture their writing on the slides 108 as a form of digital ink objects 124. The lesson creation extension 104 segments the recorded video into segments associated with individual slides 108 of the slide presentation, whereby each video object 112 is the video captured of the instructor while discussing an associated slide 108. The lesson creation extension 104 also captures the time sequence of the digital ink objects 124, which is associated with individual slides 108.
After recording, the user can edit the augmented presentation document 106 by moving or deleting slides 108, which also moves or deletes that slide's video object 112. This allows the user to easily modify the sequence of objects, and delete objects. Additionally, the user can add further slides, record video objects 112 and/or digital ink objects 124 associated with the slides 108, then edit the additional slides to thereby create the augmented presentation document 106.
Once the user has completed the creation of the augmented presentation document 106, the augmented presentation document 106 may be uploaded to a portal system 110 for sharing with other users. The portal system 110 may provide functionality for searching, rating, and viewing of uploaded lessons. The portal system 110 might also provide functionality for allowing an authorized user, such as an instructor, to view collected information as statistics regarding the viewing of augmented presentation documents 106, individual slides 108, and/or information regarding the use of quiz objects 116 and interactive lab objects 122 contained within the augmented presentation document 106. The portal system 110 might also provide forums and other types of community features for students, educators, and other users to share information regarding the lessons.
The portal system 110 may also provide functionality for playback of lessons on virtually any type of client device. In this regard, playback might be performed through the same application utilized to create an augmented presentation document 106, through the use of a playback tool implemented as a web browser plugin, through a dedicated playback application, or in another manner. During playback (e.g., for viewing by a student user), the augmented presentation document 106 presents each slide 108 in its sequence, along with the slide's video object 112. The augmented presentation document 106 may also present any digital ink object 124 for that slide 108 with timing coordinated to the video object 112 or the audio object 118, or if neither is desired the video object 112 can be substituted for a video containing only blank pictures. Additional details regarding the portal system 110 and playback of a lesson authored using the mechanisms described herein are provided below with regard to
As discussed briefly above, the lesson creation extension 104 is configured to record digital ink objects 124 in some configurations. In this way, an author can write and draw directly in the augmented presentation document 106, just as the author would on a whiteboard. Digital ink objects 124 are captured in time sequence and can be played back on the slide 108 in synchronization with the accompanying video objects 112 and/or audio objects 118. The computing device may utilize an appropriate digitizer, such as a touchscreen to enable capture of digital ink objects 124. Touchscreens are discussed further below with regard to
It should be appreciated that when the augmented presentation document 106 is played back, the augmented presentation document 106 is not presented as a video. Rather, the augmented presentation document 106 is presented as a slide presentation with accompanying video objects 112. This may result in a presentation with a higher visual quality than when video alone is utilized that is scalable across different devices. This implementation might also save network bandwidth as opposed to a pure video lesson. Recorded digital ink objects 124 may also be rendered over the image of the slide presentation.
As discussed briefly above, lessons created using the lesson creation extension 104 might be made more engaging by adding: quiz objects 116; audio objects 118; digital ink objects 124; screen-capture objects; video objects 112; interactive lab objects 122; and/or exercises to the slides 108 in the augmented presentation document 106. Quiz objects 116 provide functionality allowing quizzing of the viewer of the augmented presentation document 106. For example, and without limitation, quiz objects 116 may include true/false questions, multiple choice questions, multiple response questions, short answer questions, and/or freeform questions.
Interactive “lab” objects 122 might also be utilized in lessons created using the lesson creation extension 104. Interactive lab objects 122 may be created using HTML5/JAVASCRIPT, and/or using other technologies. In some implementations, adding an interactive lab object 122 to an augmented presentation document 106 is similar to adding clipart. Interactive lab objects 122 can be reused and can also be configured to provide analytics regarding their use to an authorized user, such as a teacher, through the portal system 110. Other types of elements or objects may also be placed in the augmented presentation document 106 and presented during playback including, but not limited to, hyperlinks 120, web page objects 114, video objects 112, audio objects 118, graphics, and other element objects. Quiz objects 116 and/or interactive lab objects 122 are added by plug-in applications to the presentation application 102 in one configuration. Quiz objects 116 and interactive lab objects 122 may also be shared and may be used by the same or different users in other lessons.
As discussed briefly above, audio objects 118 and/or video objects 112 of a user presenting the slides 108 may be recorded. In various configurations, the video is split so that the portion of video corresponding to each slide 108 may be presented separately. In this way, a consumer can view recorded video on a per slide basis. Additionally, this allows slides 108 to be rearranged (e.g. reordered, added, deleted, etc.) and the accompanying audio objects 118 and/or video objects 112 will stay with its associated slide 108. Video objects 112 and/or audio objects 118 associated with each slide 108 can also be edited or deleted separately from the video objects 112 associated with other slides 108.
The augmented presentation document 106 can be saved to a local client device in the same manner as a traditional presentation document. The augmented presentation document 106 can also be published to the portal system 110 when completed for sharing with others. During the publishing process, the augmented presentation document 106 is uploaded to the portal system 110, video objects 112 may be reformatted for web delivery, multiple resolution versions might be created for use on different devices and/or other types of processing may be performed. After publishing, the portal system 110 may perform background processing to optimize the lesson for faster play back. For example, the augmented presentation document 106 may be pre-processed for player consumption by encoding video objects 112 at different resolutions to allow for play back on slower networks. As will be described in greater detail below, a playback application may be utilized to allow a user to playback the slides 108, accompanying audio objects 118 and/or video objects 112, to engage with any quiz objects 116 and/or interactive lab objects 122 in the augmented presentation document 106 and to perform other functionality. Additional details regarding the operation of the lesson creation extension and related functionality will be provided below with regard to

For example, and as discussed briefly above, the community module 708 might be executed to provide forums, social networks, or other types of communities for discussing lessons and other topics.
From operation 908 the routine 900 proceeds to operation 910, where the portal system 110 receives a request to view a lesson, for example at the playback module 704. In response to such a request, the routine 900 proceed to operation 912, where the playback module 704 streams the identified lesson to the lesson player (described below with regard to
Utilizing one of these lesson player applications, students or other users can view, pause, rewind, or play lessons at variable speeds, helping students learn at their own pace. Playback of slides 108 and accompanying video objects 112 are synchronized and the recorded video objects 112 are displayed over the slides 108. Students view lessons on one device and pickup where they left off on another device. Students might also be permitted to take handwritten notes over the lesson.
Students can engage and interact with quiz objects 116 and/or interactive lab objects 122. When a quiz object 116 or an interactive lab object 122 is utilized, analytics 1008 are submitted to the portal. The analytics 1008 may be stored in the analytics data store 712. The analytics 1008 might also be made available to an authorized user, such as an instructor 1010. A student can stay on slides with quiz objects 116 or interactive lab objects 122 as long as needed and then move to the next slide when they are ready. The student can also view embedded content, like hyperlinks 120, video objects 112, digital ink objects 124, etc.
The player applications are multi-layered in some configurations. For example, a base layer might be configured to present the slides 108 of an augmented presentation document 106. On top of the base layer, a video layer may be configured to display the video object 112 associated with each slide. On top of that the video layer, an inking layer may be configured to display any associated digital ink object 124 that has been recorded in synchronization with the recorded audio object 118 and/or video object 112. A control layer might also be utilized that drives video, inking, seeking, move to next/previous slide, etc. In some implementations, the author can create an augmented presentation document 106 where some portions advance on user input and some portions that advance automatically.
The routine 1100 then proceeds to operation 1106 where the lesson player plays back the augmented presentation document 106, including video objects 112 recorded for each slide 108. The lesson player may replay the augmented presentation document 106 at variable speeds to help students learn at their own pace. Additionally, the lesson player may have a default playback speed at which the augmented presentation document 106 is played back. The default playback speed may be the same speed at which the lesson was recorded. In some configurations, the default playback speed may be faster or slower than the speed at which the lesson was recorded.
At operation 1108, the lesson player plays back digital ink objects 124 in synchronization with the recorded video objects 112. Synchronization allows the digital objects 124 to appear on the slides 108 at the same time as the video objects 112 appeared during the authoring process. At operation 1110, the lesson player renders any quiz objects 116, interactive lab objects 122, and/or other content contained in the presentation slides 108. The routine 1100 the proceeds to operation 1112 where it transmits analytics back to the portal system 110 for consumption by an authorized user, such as an instructor 1010. From operation 1112, the routine 1100 proceeds to operation 1114, where it ends.
