A computing arrangement and method for automatically inserting appropriate comments into documents such as homework, dissertations or essays to reduce time spent by teachers and lecturers writing the same comments repeatedly. The electronic arrangement 100 comprises a collecting entity 110 configured to collect feedback comments provided by a teacher 102 or mentor when giving feedback related to an electronic text document submitted by a student 104; an analyzing entity 112 configured to analyse subsequently submitted electronic text by detecting parts from the text document related to previously collected feedback comments; an inserting entity 114 configured to provide feedback from the collected feedback in at least functional connection with the detected part of the analyzed electronic text document. In this way, a database of feedback comments is produced and used to intelligently insert appropriate comments by analysing the text of the newly submitted document, thereby saving the teacher time. The arrangement may optionally comprise a user interface for the teacher to review the inserted feedback and revise the insertions or add further comments if required, either by typing or utilising feedback comments from the database.

Description

ELECTRONIC ARRANGEMENT AND METHOD FOR EDUCATIONAL

PURPOSES

FIELD OF THE INVENTION

S

Generally the present invention relates to computer systems. In particular, how-ever not exclusively, the present invention concerns technical arrangements and methods for collecting feedback comments and utilizing the collected feedback for educational, i.e. teaching and learning, purposes.

BACKGROUND

Teachers' -especially language teachers' -work correcting students' handouts, such as texts and essays, is often of very repetitive nature. Students' writings typ-ically contain repealing errors and therefore also teachers have to provide same or at least very similar feedback comments over and over again, from one text to another and even multiple times within the same writing. Obviously this is ex-tremely frustrating and time-consuming.

Even though more and more education is shifting into electronic fonn and stu-dents are able to hand in tasks electronically, teachers are still forced to use their valuable time and expertise to such enor correction that could ideally take place automatically. If conection for repetitive errors was somewhat automated or oth- erwise facilitated, there would naturally be more time for teachers to help stu-dents in problems that really require their expertise.

Today, electronic fonns with ready-made choices can be scanned through and coiTected automatically. Written text on the other hand is still problematic. There is software that conects text documents according to preprogrammed rules which may include correcting misspelling or basic grammar issues. Such relatively straightforward correction methods can be found for example in Microsoft Office ToolsTM. However, these correction arrangements are not really suitable for teaching purposes as no personalized feedback is provided for the user writing the text mid, hence, the user will not learn from his/her mistakes. Furthermore, such software tools do not benefit from the knowledge and expertise teachers possess and therefore, the feedback will not meet the standard of education.

SUMMARY OF TIlE INVENTION

The objective is to at least alleviate the problems described hereinabove not yet satisfactorily solved by the known arrangements, and to provide a feasible solu-tion for collecting given feedback for electronic text documents and subsequently utilizing such given feedback automatically in a text correction process.

The aforesaid objective is achieved by the embodiments of an arrangement and a method in accordance with the present invention. The presented solution may be applied for providing teachers or other persons in an educational or mentor role with supporting teaching means that collects automatically given feedback and utilizes such previously provided feedback in future teaching optionally substan-tially instantaneously. Alike, the embodiments of the arrangement and method may provide a person in a student role with enriched and high-quality feedback for every text document.

Accordingly, in one aspect of the present invention an electronic arrangement, preferably including at least one network server optionally provided in a cloud environment and one or more client devices like comnputer tenninals, comprises -a collecting entity configured to collect feedback comnnients provided by a fu'st user having a mentor role when the first user is giving feedback to an electronic text document via a terminal, the document provided by a second user having a student role via a terminal, -an analyzing entity configured to analyze the electronic text document provided by the second user or a third user having a student role by detecting parts from the text document related to previously collected feedback comments, and -an inserting entity configured to provide feedback from the collected feedback in at least functional connection with the detected part of the analyzed electronic text document.

In one embodimnent the analyzing entity may further comprise an error detection entity configured to detect basic errors, such as misspelling or basic grammar er-rors, according to predetermined logic. It may flmrther be arranged to highlight the error (e.g. visually by color, underlining, etc.) andlor correct it automatically or upon obtaining permission from the user such as a teacher, for instance.

In another, either supplementary or alternative, embodiment the terminals for the first and second user may be connected to a communications or computer net-work, optionally the World Wide Web (WWW) system. The second user may be a student submitting a text document over the network to the first user, e.g. a teacher, who may review the text document utilizing his/her terminal. The ar-rangement of the present invention may automatically provide the submitted text document with suitable feedback (the feedback may be integrated with the doc-ument or provided as at least associated with the document, for instance). The teacher may thereafter review the text document and manually add, delete and/or modif5' the feedback comments ultimately to be given to the student. Optionally, the second user may be in some embodiments provided with feedback comments even before forwarding the text document to the fir st user.

In a further, either supplementary or alternative, embodiment the collecting entity is configured to collect feedback comments, which are typically realized as data, interpretable by a number of computing and software entities. The feedback may be provided by a user in a mentor role. The feedback may be captured via any available input teclmology such as keyboard, keypad, speech recognizer, touchscreen, buttons, switches, mouse, touchpad, etc. Such mentor role user may be a teacher or assistant in an educational enviromnent or a parent teaching or as-sisting his/her child, for example.

Texts related to a certain field such as art, science or literature may follow a set of guidelines and/or rules which may differ from a text related to another field.

Embodiments of the present invention may function interdisciplinary. In oilier words, the collected feedback is not necessarily restricted to a certain field. The arrangement may collect given feedback data from a text related to one field and utilize such feedback data in texts from other fields. The arrangement may be configured to recognize the field, though, store indication thereof with the feed-back and use the information afterwards during analysis and/or insertion to properly recognize matches between the feedback and the text (provided by the second or third user) and/or to optimize the feedback provision (which may be

field-specific/field-adapted), respectively.

In a further, either supplementary or alternative, embodiment a user in a student role may provide electronic text documents such as an essay, letter or scientific publication for review, for example. Electronic text document may be any written material in electronic from provided in various formats such as.doc, .xls, .ppt pdf, HTML etc..

A user in a mentor role may then review the provided material and preferably give feedback comments related to the material. Feedback comments may relate to content, style, grammar, punctuation and/or misspelling, for example.

In a further, either supplementary or alternative, embodiment the arrangement may be configured to collect feedback data from more than one user. The ar-rangement may thus, consist of several users in a mentor role, optionally teachers from same and/or different educational establishments. The feedback provided by users in the aforementioned mentor role may be collected together and stored, preferably in a server network optionally provided in a cloud enviromnent.

Therefore a user in a mentor role may in one embodiment of the present inven-tion access the feedback data collected (also or solely) from another user(s) hi a mentor role and, hence, utilize such data for own teaching purposes. A user, pref-erably a user in a mentor role, may select a source of the provided feedback comments by selecting feedback comments to be provided from feedback col-lected from one user or a group of users. Optionally or additionally, the provided feedback comments may follow specific guidelines such as instructions presented by an educational establishment, wilting style or test requirements, for example.

Alternatively, a user may choose to utilize all the collected feedback coimnents stored by the arrangement when providing feedback comments.

In a further, either supplementary or alternative, embodiment the arrangement may comprise a pluginlapplication such as a web browser extensionladd-on or a dedicated (potentially stand-alone) application to provide at least local UI to the users thereof. Additionally or alternatively, it may incorporate a remote service entity optionally hosted by a plurality of servers potentially implemented in a cloud environment. In one embodiment of the present invention the user in a stu-dent role may get feedback comments for his/her text even before submitting it to the (remote) arrangement and/or the user in a mentor role, which feedback coin- ments may be provided via the aforementioned terminal plugin or application lo-cally.

In another aspect of the present invention, a method for personalized feedback provision to be performed by an electronic arrangement preferably including at least a terminal device and/or a network server, comprises -providing an electronic text document by a second user in a student role, -adding feedback comments manually by a first user in a mentor role, -collecting feedback comments, provided by the first user in a mentor role, with a S feedback comment collecting entity, -analyzing text document with an analyzing entity configured to analyze the elec-tronic text document provided by the second user or a third user having a student role by detecting parts from the text document related to previously collected feedback comments, -inserting feedback comments with an inserting entity configured to provide feedback comments from the collected feedback comments in at least functional connection with the detected part of the analyzed electronic text document.

As mentioned above, the method may be perfonned by one or a plurality of enti-ties, such as a tenninal device and/or a server. The server may provide data to the terminal device such as previously collected feedback data and/or receive data such as user entered input data from the terminal device.

In one embodiment, a user in a student role provides an electronic text which may then be reviewed by a user in a mentor role. The user in a mentor role may manually add feedback to the text, which feedback is then collected and stored by the arrangement, preferably in a network accessible server. Such collected feed-back may then be utilized by an analyzing entity which may detect part(s) of the electronic text related to previously collected feedback. An inserting entity may thereafter provide the part(s) with feedback from the collected feedback.

In another, either supplementary or alternative, embodiment a user in a student role provides an electronic text which may thereafter be analyzed by an analyzing entity configured to notice parts related to feedback stored by the arrangement.

An inserting entity may thereafter provide the noticed part with feedback from previously collected feedback. When the feedback is provided, the user in the mentor role may go through the material and add, delete and/or modify feedback comments manually. The manually added and/or modified feedback may then be collected by a collecting entity and stored by the arrangement.

The utility of the present invention follows from a plurality of factors depending on each particular embodiment. The suggested solution may allow rich feedback on any written work. It may provide establishing and maintaining a dynamic feedback comment database. It may also provide a unanimous feedback database for teaching personnel in same and/or separate educational establishments, hence, making it possible for teaching personnel to benefit from each other's knowledge and expertise in real time.

The suggested arrangement may evolve organically in use as the database con- taining feedback data may expand over time. By expanding the database, execu-tion of the teaching and feedback tasks gets easier (requiring less manual work) and faster. Individual/Initial feedback comments may also improve in quality as the users may be allowed to modif3 and specilj the comments later on. The ar-rangement may, on the other hand, be utilized to ensure that a student will always get the same, high quality feedback to his/her (textual) input. The suggested ar-rangernent may provide an offline and/or online working tool with a flexible and easy-to-adopt user interface (UI). I5

The suggested arrangement may solve the issue of tedious, repetitive feedback commenting. With the suggested arrangement a user may have to provide a cer-tain comment only once, after which the arrangement may store the comment and provide it automatically later on.

By using detailed, pertinent descriptions, flexible fonnatting and links to addi- tional inatenals, students may learn from each comment they get. Every com-ment given through the suggested arrangement may be used to improve both teaching and learning experiences. Additionally, given feedback may be analyzed using statistics and overviews, hence, improving the teaching personnel's work and the students' personal development.

The expression "a number of' refers herein to any positive integer starting from one (1), e.g. to one, two, or three.

The expression "a plurality of' refers herein to any positive integer starting ftom two (2), e.g. to two, three, or four.

Different embodiments of the present invention are disclosed in die dependent claims.

DETAILED DESCRIPTION OF THE EMBODIMENTS

Figure 1 illustrates, at 100, an embodiment of an arrangement in accordance with the present invention with a conceptual approach.

A second user 104, e.g. a school student, may use a client (terminal) device lO6b for submitting electronic material such as a written text document. The client de-vice I 06b may be a laptop computer, desktop computer, tablet, smartphone or any other conventional computing device applicable to comiect to a network 116 and remote entities such as the arrangement 108 accessible through it via suitable conununications teclmology like the World Wide Web (WWW). The user 104 may create a text document with the same or any other applicable terminal device utilizing e.g. text generating software or text editor' known by a skilled person.

Such text generating software may be part of the arrangement of the present in-vention or separate software provided by a third party entity.

A first user 102, e.g. a teacher, may use another client (tenninal) device 106a for reviewing a text document provided by a student. The client device 106a may as well be a laptop computer, desktop computer, tablet, smartphone or any other conventional computing device applicable to connect to a network 116 such as the World Wide Web (WWW) and remote entities such as the arrangement 108.

A teacher may utilize the client device to give feedback by adding comments to the document provided by a student. The feedback content may relate to any top-ic that requires the knowledge or expertise by the reviewer. Such feedback may relate to style, grammar, punctuation and/or misspelling for example. A skilled person may understand that a feedback comment may refer to a single character of a text, e.g. a letter or mark, or a section such as a sentence, paragraph or the whole text. It may also be understood by a skilled person that one section may contain several comments or feedback as one sentence may consist of several er-

rors, for example.

The arrangement 108 may include a computing entity such as a number of serv-ers optionally in a cloud environment for enabling flexible capacity allocation among other benefits. The arrangement 108 may be considered to include a data collecting entity 110 configured to collect feedback comment data provided by the first user 102 in a mentor role. The feedback comment data may then be stored in the server arrangement 108.

An analyzing entity 112 may be configured to process electronic text and detect relevant parts according to previously collected feedback comments. In detail, the analyzing entity may adapt with the collected feedback and, hence, detect sec-tions that require feedback comments based on the collected feedback comments.

The analyzing entity may be configured to compare collected feedback comment data with the provided text, character by character, string by string, sentence by sentence and/or by utilizing Big Data' analyzing methods, semantic analyzes etc..

An inserting entity 114 may be configured to provide the detected parts that re- quire feedback with feedback comments suitable for the part. The stored feed-back comments may be provided as such or adapted to better suit the part in question by following available adaptation logic. The user may be able to adjust the topics taken into consideration when providing feedback. The user may hence, for example, select only to give feedback on grammar and spelling. The feedback will then be provided in at least functional connection with the part of the text it is refelTing to which will be explained hi more detail with reference to Figure 3.

Figure 2 is a block diagram representing, at 200, the internals of an embodiment of the arrangement, such as the one of Figure 1, with particular emphasis on the related hardware. A computing entity 208 such as a number of servers optionally in a cloud environment may include a number of processing entities 220a such as microprocessors, microcontrollers, digital signal processors (DSPs), programma-ble logic chips, etc. for executing instructions and processing data potentially stored in a number of memory entities such as memory chips 226a. In some em-bodiments, memory and processing entities may be integrated. The instructions for collecting feedback data, analyzing electronic material and/or providing elec-tronic material with feedback data, for example, may be executed by software application(s) 228a. Soffivare (computer program product) may optionally be transported and stored using a physical, tangible carrier medium such as a memory stick, memory card, or optical disc. Alternatively it may be sent over a network over a wired or wireless medium.

User Interface (UI) 224a may refer to both local and remote UI for controlling the hardware of the computing entity 208 itself and/or the executed software providing the data collection, analyze and/or provision, for example. Local UI may comprise a display or other output device and mouse, keyboard and/or touch surface for allowing user input. Remote UI may be provided via a data transfer interface 222a such as a network interface, optionally Ethernet or other Local Ar- ea Network (LAN) interface. The data transfer interface allows connecting to ex-ternal network(s) 216 such as the internet enabling necessary communication with remote tenninal devices 206a, 206b. Browser-based UI with e.g. HTTP and HTML (HyperText Markup Language) may be used, for example. In some em-bodiments, the arrangement is configured to provide a user with a user (account) information web page such as a home page', or a plurality of related pages, or other personal data contemplation and/or management thfrastructure.

The client tenninal devices 206a, 206b for accessing the service (if not being stand-alone devices provided with local copy of a feedback database, etc., vhich is valid option even in scenarios wherein reniote service 208 is implemented but temporally unavailable/unaccessible) provided by the remaining arrangement, or at least connecting to the alTangement, generally include corresponding elements such as processing entity 220, memory entity 226, at least one data transfer inter- face 222 such as a cellular and/or wired network (e.g. Ethernet or other LAN) in-terface, software logic 228 such as a browser extension or stand-alone application for connecting the remote server 208 and UI 224 such as mouse or keyboard, op-tionally e.g. touchscreen as being common with mobile terminals such as tablets and smartphones at the time of writing. In some embodiments, the arrangement of the present invention may be executed independently, or partially, in the client terminal devices 206a, 206b by a number of processing entities 220, memory en-tities andlor software logics 228.

Figure 3 shows an example, at 300, of an embodiment of e.g. a browser-based Iii of the present invention. The UI may contain a field 302 for an electronic text, provided by a student for example. An electronic text document may be any writ-ten material in electronic form such as an essay, letter or scientific publication and it may be provided in various formats such as.doc, .xls, .ppt.pdf, HTML etc.. The text may be initially analyzed automatically by the arrangement and provided with marks suggesting feedback for that section. In some embodiments, a student submitting a text may be provided with the automated feedback even before forwarding it to a tutor. Hereby, a student may make the suggested correc-tions immediately and submit a far more supenor text to the tutor. I5

Still referring to Figure 3, the arrangement may analyze the text and provide feedback automatically based on previously collected feedback data. A teacher may review the text and add, delete and/or modify comments manually. A teach-er may create new feedback categories and/or subcategones. As may be noticed from the UI, feedback for a certain section in the text may be highlighted with colored background and/or numbers next to the section, for example. Different colonng may represent a certain type of error or other issue such as misspelling or some specific grammar related issue. Optionally, in some embodiments, one color may represent the number of layers of error for that section. For example, sections 1 and 2 in field 302 could be colored with yellow, which would indicate that these two sections contain only one layer of error. Section 3 on the other hand could have a differeilt color, e.g. green, because it's located on top of sec-tion 2 and therefore represents a section with two layers of error which would therefore be beneficial to differentiate from sections 1 and 2 that represent one layer of error.

When choosing a highlighted section, for example by clicking' the section with a computer mouse cursor or via a touchscreen, for instance, the feedback or conuneilt related to that section may appear in the comment field 304. The coin-ment may be modified by the user in the teaching role.

The UI 300 shows by way of example an option menu 306 wherefrom the user may choose feedback topics that are shown in the text. Optionally, such feature may be provided only for the teacher or both teacher and student. Thus, a teacher may choose to concentrate only on a few topics at once and provide the student with reduced feedback. Hereby, the student and teacher may work on the text it-eratively and the student will not be overloaded with feedback. A user may also choose to provide feedback collected from one user or a group of users, for ex- ample. Optionally or additionally a user may choose to provide feedback accord-ing to specific guidelines such as rules presented by an educational establishment or a writing style, for example.

Figure 4 shows by way of example, a browser-based UI of a statistical view. The view, at 400, may represent statistics over one text document, for example. Sta-tistics may show the number of comments by category and provide such data in various visual ways for helping the user perceive the information. A pie chart 402 is shown as a representation of the visualization, by way of example only.

The arrangement of the present invention may provide oilier statistics as well.

For example, a teacher may review statistics of a group of students' success re-garding one task, a course and/or time period. A student on the other hand may review his/her development by getting statistics of the feedback appearing in his/her texts during a time period.

Figure 5 discloses, by way of example, a method flow diagram hi accordance with an embodiment of the present invention for feedback data collection, elec- tronic text analyzes and feedback insertion to be performed by an electronic ar-rangement, such as at least one terminal device preferably functionally connected to a server entity optionally in a cloud environment.

At method start-up 502, typical preparatory actions may take place. Necessary equipment such as terminal device and server arrangement may be acquired, con-figured, provided with necessary software, etc. At 504, a user, e.g. a student, provides the arrangement of the present invention with electronic text via a terminal device. The step may comprise that a user cre-ates an electronic text document by any conventional mamier, such as Microsoft \kTord TM, E-Mail, Chat applications etc. and submits such text to the arrangement of the present invention which may be provided as a separate arrangement. Op-tionally, the arrangement of the present invention may be integrated in a text generating program.

At 506, a user gives feedback manually to a text provided at 504. The user may be a teacher whose expertise is utilized to giving feedback to the text. The step may comprise that the teacher reviews a text, marks parts of the text and adds feedback comments in functional connection with the marked part by using a cli-ent device's input means.

At 508, the entities of the present invention collect the feedback provided at step 506 and store it, preferably in a server database. The entities may be executed by a number of computing and/or software entities explained hereinabove.

At 510, the entities of the present invention analyze electronic text by noticing parts fiom the text according to previously collected feedback comments. The en- tities may be executed by a number of computing and/or software entities ex-plained hereinabove. I5

At 5 12, the entities of the present invention provide feedback to the analyzed electronic text from the collected feedback. In this step marks may appear in the text and feedback comments related to the marked part may be reviewed via a UI.

At 5 14, die method execution is ended.

As being understood by a skilled person the mutual ordering of the presented steps may be varied. For example, the arrangement naturally needs to collect some initial feedback data in order to being able to provide any feedback regard-ing piece of electronic text inputted for obtaining related guidance/comments.

However, after the arrangement have gathered at least some feedback data, steps 506 and 508 may be hi some embodiments ignored, which is presented with the dotted lines, as the arrangement may directly provide automatically feedback from previously collected feedback to a new text document as is executed at 510 and 512.

As a supplementary or alternative way of execution, in some embodiments, steps 506 and 508 may be executed after step 512 which is presented with a dotted ar-rowed line. After the arrangement has provided the electronic text \vith feedback at 512, a mentor role user may personally review the text and add, delete and/or modify the feedback manually. in Ii

As is understood by a skilled person, several terminal devices may be connected to the arrangement even at the same time and, hence, submissions, analyzes, modifications or other steps in the method may be overlapping or run in parallel relative to each other.

Method items may be executed by a computer program product embodied in a non-transitory carrier medium, such as optical disc or memory card.

Consequently, a skilled person may on the basis of this disclosure and general knowledge apply the provided teachings in order to implement the scope of the present invention as defined by the appended claims in each particular use case with necessary modifications, deletions, and additions.
