The present invention enables a providing students and teachers with a tool (also referred to herein as “snapshot tool”) that enables direct messaging between teachers students. Although for the sake of simplicity students and teachers are mainly referred to herein, it will be understood that any other users may be relevant, for example, some embodiments of the invention may be used by pupils, instructors, etc
As described herein, a snapshot tool provided by embodiments of the invention enables capturing content in a display screen of a student, enabling the student to add information to the captured content and sending the captured content and added information to a teacher or other recipient In an exemplary scenario carried out by a system according to an embodiment, a student is provided with a pedagogical element such as a game. During the game (e.g., when completing a level in the game), a snapshot of the screen is captured. The snapshot is then converted to an image (e.g., according to the Joint Photographic Experts Group (JPEG) format). The image is saved in the student's account. A system may then enable the student to associate content with the image. For example, the student is provided, by a system, with a text tool for entering text and associating the text with the image. For example, the image and text are included in a pedagogical element and the pedagogical element is stored in associating with the student's account.
The pedagogical element may be submitted to a teacher. The teacher may add content to the pedagogical element. For example, the teacher may be provided with a text tool, a draw tool and/or an erase tool and may use these tools to add an assessment to the pedagogical element. A pedagogical element that includes an assessment from a teacher may be provided to the student.
As described herein, a tool provided by some embodiments of the invention enables a teacher to review content received from a student, revise the content or add information to the content, and return the revised or modified content to the student. Accordingly, a system and method according to some embodiments of the invention enable students to use, consume, or interact with educational or other content and provide teachers with feedback related to the content, where the feedback is provided with at least a snapshot related to the content. A system and method according to some embodiments of the invention enable teachers to return feedback or instructions to students where the feedback or instructions from teachers include a snapshot of the relevant content. A tool described herein may be part of, or included in an online system that connects teachers and students and allows direct messaging between the teachers and each of the students or direct messaging between a teacher and a group of students.
As described herein, a snapshot tool may draw, capture or obtain student assessment data For example, in an embodiment, the snapshot tool captures a screenshot of a display of a student's computer (that may be similar to device 100) and the snapshot tool may finther enable the student to add comments or other information to the screenshot to generate assessment data.
In an embodiment, the snapshot tool enables or allows easy transfer of assessment data to the teacher, the snapshot tool enables the teacher to revise the assessment data (e.g., add comments) and send the revised assessment data back to the student
In an embodiment, the snapshot tool captures a screenshot of content on a display of a student (e.g., content such as a video, a game or educational content), converts the screenshot into an image (e.g., as a JPG file), and saves an image of the screenshot
In an embodiment, the snapshot tool enables a user (e.g., a student) to write comments related to the captured screenshot and the snapshot tool further submits the image of the captured screenshot and comments of the user to a teacher or to a system.
Accordingly, an embodiment of the invention may create an artifact from a learning activity, and send the artifact to a teacher for assessment. For example, an embodiment may include packaging of the snapshot tool as a Flash library so that it may be included in a source code of a Flash game or content, that allows easily implementation of the snapshot tool within that Flash game or content.
When running on a user's device, a module or unit, e.g., the snapshot tool, may include a graphical user interface (GUI) button labeled “TAKE SNAPSHOT” Reference is made to FIG. 2 that shows a screen capture of an exemplary screen that may be presented on a display of a user As shown by button 210, a “TAKE SNAPSHOT” button may be added to content presented by a game or other entity. For example, code included in the code that generates and/or presents a game as shown by FIG. 2 may cause button 210 to be presented as shown.
Clicking button 210 may cause a screenshot to be taken and stored. In some cases, the clicking button 210 may also trigger or cause a quick white flash over the game with an accompanying shutter sound to indicate, with minimal disruption to the play, that a snapshot was taken. In an embodiment, when clicked, button 210 may briefly but prominently change color (e.g., to read) and may further replace (e.g., for three seconds) the label of “TAKE SNAPSHOT” to “SNAPSHOT SAVED”. Accordingly, a system and method may enable a user to store a snapshot of a screen by clicking a button embedded in content presented by an application Otherwise described, a button used by a user to capture and store a screenshot may be included in content presented by any application and a user may use the button within the context or screen of the application, without having to leave or exit the application
Once a snapshot has been saved, a “VIEW SNAPSHOTS” button may be added. Reference is made to FIG. 3 that shows a screen capture of an exemplary screen that may be presented on a display of a user. As shown by button 310, a “VIEW SNAPSHOTS” button may be added to content presented by a game or other entity. For example, the button may be added using a system and method as described with reference to button 210 Accordingly, a system and method may enable a user to view snapshots by clicking a button embedded in content presented by an application.
Clicking the “VIEW SNAPSHOTS” button may launch a pop-up with a text entry field for the user to write comments about his or her snapshots. For example, all snapshots may be presented (e.g., as thumbnails or in full size) with the most recent snapshot in focus. A roll of preview thumbnails may be provided to allow a user to select, edit, delete and rearrange snapshots A unit may enable a user to save any number of snapshots snapshots in each session. In some embodiments, the number of snapshots that may be saved for each session may be limited by a threshold, e.g., only five snapshots may be saved and/or submitted as further described herein
When a session ends, e.g., the user has finished or completed a game session, a unit or module may enable the user to submit the screenshots, e.g., to a database or to a teacher. For example, a system as described herein may include user accounts that may be stored on and supported by a server and screenshots and any content generated by a user (e.g., comments added to a screenshot) may be stored in a user's account. For example, all screenshots and related comments may be stored as a group that may be associated with the session that the user was involved in when the screenshots were taken. A group of screenshots (or an individual, or specific screenshot) may be associated with a game, a lesson, an activity, a teacher, a subject (e.g., history, geography etc), a timestamp or any other metadata.
A system and method may enable a user to edit saved screenshots. For example, clicking on a saved screenshot presented as described herein may open or display the saved screen shot and enable editing the saved screenshot. A system and method may enable a user to save a screenshot after editing.
Reference is made to FIG. 4 that shows a screen capture of an exemplary screen that may be presented on a display of a user. As shown by button 410, a “SAVE” button may be added to content in a saved snapshot, e.g., a snapshot saved in a user's account as described. For example, button 410 may be added using a system and method as described with reference to button 210 Accordingly, a system and method may enable a user to edit screenshots and save edited or modified snapshots by clicking a button embedded in content presented by an application
Clicking the button 410 may add any text entered by a user to the saved snapshot A spinner may be presented while changes to a screenshot are being saved, e.g., locally, on the user computer or device or on a remote server. The save button (e.g., button 410) may be removed after saving a screenshot. The save button may automatically be presented when a text field is selected again, or when a different screenshot is selected for editing. For example, when clicking a saved screenshots, text field for entering text may be presented in a window as shown in FIG. 4, above save button 410.
A system and method may enable supervising of an activity. For example, a teacher may be involved in educational activities of students by receiving activity reports from students, receiving comments from students, providing assessments etc For example, an activity page may be presented as described herein and may further be used to enable students and teachers or personnel to exchange or communicate information related to activities as described herein.
Reference is made to FIG. 5 that shows a screen capture of an exemplary screen that may be presented on a display of a user. As shown by the row of buttons 510 at the bottom of the page, other than a save button and a submit button, an edit button, an erase button and an edit button may be included in a display.
Typically, only one tool (represented by buttons 510) may be active at a given time. A default button may be made the active button by a system, e.g., the text entry tool may be active by default. The button of the currently active tool may be darkened or made to match the color of the active tab at the top of the page. It will be understood that any buttons may be presented in any screen, e.g., based on a configuration of the unit that presents the buttons. For example, in one configuration, an application that presents buttons as described herein may only cause the drawing tools to appear on the activity screen or tab but may remove the drawing button when a user moves to the vocabulary tab shown at the top of FIG. 5.
The save button may save the activity to the student's account. When an activity is saved, a row of progress boxes may be presented next to the save button as shown. For example, the boxes may represent the number of activity pages available for the current topic, and indicate the number of activities already completed. Information presented by the progress boxes (e.g., number of tasks or activities completed) may be stored on a server and may be presented to both a student and a teacher. Accordingly, a system and method may enable both student and teacher to track a progress of the student.
For example, when an activity is saved, the corresponding box will get a white fill to indicate that the activity has been saved The submit to teacher button may only send data related the currently selected tab to the teacher. Submitting unsaved changes may automatically save those changes. Once an activity is submitted, the save and submit options may no longer be presented
Snapshots (e.g., of a session) may be presented to a student. A presentation of snapshots taken during a session may include buttons to enable a student to review a snapshot, submit a snapshot or perform other actions.
Reference is made to FIG. 6 that shows a screen capture of an exemplary screen that may be presented on a display of a user. As shown, snapshots of a session may be presented, e.g., to a student, in a timeline view. A students can use a display as shown by FIG. 6 to submit snapshots by pressing the submit button shown next to each snapshot. A user may further view and edit a saved snapshot by clicking the view button next to the snapshot as shown in FIG. 6. For example, clicking the view button may cause a unit to open or present a page that may be similar to the activity view shown in FIG. 5.
Snapshots of a session or game may be displayed in a numbered column, with the student's comments placed under the corresponding snapshot. Reference is made to FIG. 7 that shows a screen capture of an exemplary screen that may be presented on a display of a user. As shown, text entered by a student, in connection to the snapshot, may be presented under the snapshot.
A system and method may enable a teacher to add comments to a snapshot and a system and method may present to a student comments related to the snapshot, as entered by a teacher.
Reference is made to FIG. 8 that shows a screen capture of an exemplary screen that may be presented on a display of a user. As shown, text entered by a teacher may be presented using a wider version of the page shown in FIG. 7 where an additional column on the right displays teacher's comments next to each snapshot.
As described herein, activities may be saved, e.g., including any text entered by a student that performed the activity. Reference is made to FIG. 9 that shows a screen capture of an exemplary screen that may be presented on a display of a user For example, as described, snapshots (e.g., related to activities) may be submitted to, or saved on, a server. Saved snapshots may be sent from a server to a user's computer and presented thereon (e.g., presented on a computer of a student or teacher). As shown in FIG. 9, saved snapshots' pages may be displayed as single tabbed images, with the tabs allowing the user to toggle or scroll through their saved activities. As shown in FIG. 9, a set of tabs may present snapshots for a respective set of activities. For example, a first tab for vocabulary, and a second tab for activity may be presented.
For example, as shown, tab 910 is the one selected and therefore a saved snapshot of “activity” is shown. In this example, if the user selects tab 920, snapshots of activities related to vocabulary will be displayed.
In one embodiment, presenting tabs as shown in FIG. 9 is selective For example, if no snapshots or other content were saved by a user for a specific topic, activity, subject or field, then a tab for that field or activity is not shown. For example, for a student who did not save any snapshots related to vocabulary activities, tab 920 is not shown. Accordingly, tab 920 being displayed as shown may be an indication that activities related to vocabulary were saved.
A system and method according to embodiments of the invention may enable a teacher (or any other authorized person) to review content submitted by students. For example, a teacher may open an activity submitted by a student, may add comments or other content to the saved activity and save the revised activity The student may then open the revised activity and see any content added by the teacher. Content added by a teacher may be text, e.g., entered in dedicated text fields or it may be graphical content, e.g., an image or other a drawing, e.g., as exemplified in FIG. 11
Reference is made to FIG. 10 that shows a screen capture of an exemplary screen that may be presented on a display of a teacher. As shown by text entry field 1010, a text entry field may enable a teacher to enter text for, or in relation to, a saved snapshot. As shown by button 1015, a “SEND COMMENTS” button enables a teacher to send the comments. Sending comments may include at least storing or saving the revised snapshot on a server. Accordingly, a student may open a revised snapshot and see the comments or other content added by the teacher
For reviewing activities, a teacher may be provided with a screen similar to the activity screen presented to a student. Reference is made to FIG. 11 that shows a screen capture of an exemplary screen that may be presented on a display of a teacher. As shown in FIG. 11, the same tabbed navigation may be used for both student and teacher. The teacher may further be provided with other graphic tools, e.g., a drawing tool that enables adding a drawing as shown by drawing 1110.
In an embodiment, clients are provided with executable code that is executed on their computers. In the description that follows, postMessage is a built-in browser method for communicating data between windows and ExternalInterface is a built-in Flash Player method for communicating data between Actionscripts and Javascripts.
For example, a precompiled Flash Actionscript (e.g., BrainPOPScreenSend.swc described herein) included in a Flash Actionscript 3 project is installed on clients' computers. For example, BrainPOPScreenSend.swc is code that captures screenshots from Flash, encodes captured screenshots or images, and the transfers images to Javascript.
In an embodiment, BrainPOPScreenSend.swc is imported into a Flash project. To initialize the core class of BrainPOPScreenSend.swc, a line of Actionscript is added to the project, for example, “var screenSender:ScreenSender=new ScreenSender (stage)” The project is then exported as, or converted to, swf file or format, and the swf code is then embedded in an HTML page that may be served to students and teachers. The HTML page may be hosted on any web site, and may be included as an ifiame within a default HTML page of a site, e.g., www.BrainPOP.com.
To allow cross-domain communication between the Flash project and the HTML page, a JavaScript method (e.g., postMessage included in module or unit cameraProxy.js as described herein) is used as a bridge between the 2 domains.
In an embodiment, a software package installed on client computers includes a ScreenSender as unit, module or class that manages capturing, encoding and transfer of images; a adobe images JPGEncoder as class or unit that converts bitmap data into JPEG format images and known or public classes, e.g., adobe images.BitString.as (documented at https://github.com/mikechambers/as3corelib) and dynamicflash util Base64 as (documented at http://dynamicflash.com/goodies/base64). Module or unit cameraProxy.js allows users to set the size and quality of captured images, and may communicate with both a Flash object and a web page at or in a web site. A JavaScript in a web page at a site (e.g., module- or unit captureCrossDomain.js described herein) may communicate with the cameraProxy.js script and cause module or unit cameraProxy.js to capture images. Code in unit cameraProxy.js may enable users to set the size and quality of captured images, and may further communicate with both the Flash object and a web page at a web site
A JavaScript (e.g., module or unit captureCrossDomain.js described herein) may store the captured snapshots or images and user text or other related content, may handle additions to, and removals from images, or perform other manipulations of stored snapshots as described herein. CameraProxy.js allows partners to set the size and quality of captured images, and can communicate with both Flash objects in a Flash project and any entity in a web page at a web site
An embodiment of the invention uses web technologies for capturing and tracking screenshots, notes and metadata from students and teachers. Reference is made to FIG. 12 that shows an exemplary flow and exemplary components according to embodiments of the invention. FIG. 12 shows a flow that may be used to capture, edit, save and present snapshots as described herein. As shown, a system or flow may include a server 1205 that may be a web server as known in the art As shown, a system or flow may include a client 1206. The client side shown in FIG. 12 may be any user, e.g., a student or a teacher. For example, server 1205 and client 1206 may be computing devices similar to computing device 100 or may include similar elements. For example, server 1205 and client 1206 may each include a controller 105, memory 120 and executable code 125.
As shown, a system may include a cptureCrossDomain.js script 1210, a cameraProxy.js script 1215 and a Flash project 1220. As shown, module or unit captureCrossDomain.js may be executed when the “TAKE SNAPSHOT” button (e.g., present beneath an iframe) is clicked. As shown, module or unit captureCrossDomain.js may, using postMessage, send a message to cameraProxy.js on the client computer.
As shown, cameraProxy.js may, using ExternalInterface, send a capture request to ScreenSender as (included in Flash project 1220 as shown) specifying in the capture request parameters such as size and image quality. As shown, in response to the request, ScreenSender as may create an empty bitmap, thaws Flash pixels to the bitmap, scale the bitmap to the specified size, encode the bitmap as a JPEG image, and then encode the JPEG as a Base64-encoded string to produce a Base64 encoded image.
As shown, ScreenSender as may further send the Base64 encoded image to cameraProxy.js, using ExternalInterface. As shown, cameraProxy.js may send the Base64 encoded image to module or unit captureCrossDomain.js using postMessage. As shown, module or unit captureCrossDomain.js may display the captured image in an overlay For example, the window shown in FIG. 4 is overlaid on or over a screen or presentation of a game Otherwise described, module or unit captureCrossDomain.js may (possibly temporarily) superimpose any graphical content over a presentation of pedagogical content.
Captured images may be removed, re-ordered and annotated as described herein, e.g., by module or unit captureCrossDomain.js and based on user input. For example, additions or modifications to snapshots made by teachers and students as described herein may be performed by captureCrossDomain.js. As changes are made, updates may be sent, e.g., using an application programming interface (API), to a server or backend system that stores the images, text, student or teacher metadata etc. Once a screenshot and its associated data are stored on a server or backend system, a student can share/submit them to his teacher for comments. The teacher can then view the student's screenshot and/or text, make comments and send a revised screenshot back to the student. The student can then view his original screenshot and annotation as well as the teacher's textual comments or other input.
Reference is made to FIG. 13, a flowchart describing a method according to certain embodiments of the invention. As shown by block 1310, a method or flow may include capturing a screenshot of a presentation of an educational content object For example, an object presented may be a pedagogical element such as a game or activity. A “TAKE SNAPSHOT” may be embedded in the content object, presented to a student and used to capture a screenshot of a screen of a computer of the student. For example, the educational content object or pedagogical element and “TAKE SNAPSHOT” button may be presented by Flash code embedded included in a web page downloaded by the student.
As shown by block 1315, a method or flow may include converting the screenshot to an image. For example, a screenshot (that may be a bitmap as known in the art) is converted to JPEG format to produce an image file. As shown by block 1320, a method or flow may include receiving comments from the student and including the comments and image in a pedagogical element For example, text entered by a student using a text field as described may be combined with an image of a screenshot and the combined content may be stored as a pedagogical element.
As shown by block 1325, a method or flow may include submitting the pedagogical element to a teacher. For example, after a pedagogical element is submitted by a student, the teacher is notified that a submission is waiting for review. A notification may include the students name or other details, the related subject etc.
As shown by block 1330, a method or flow may include receiving an assessment from the teacher and including the assessment in the pedagogical element to produce a revised pedagogical element. For example, comments or drawings (e.g., as shown by FIG. 11) may be entered by a teacher when reviewing work submitted by a student as described
As shown by block 1335, a method or flow may include presenting the revised pedagogical element to the student. For example, a student may be notified that his or her work was reviewed by a teacher, may log into his or her account and may be presented with comments entered by the teacher with reference to submitted work
