step 001: the server a records the recorded and broadcast video corresponding to the teaching courseware, and the courseware operating instructions of the teaching courseware are synchronously stored by the operator in the recording process of the recorded and broadcast video.

The teaching video can be understood as a video file containing a teacher and/or a student, that is, a video file related to the teacher lecture, and in this embodiment, the teaching video may be a video file already recorded, or a video file recorded by the teacher during the course of teaching. In the embodiment of the application, the video file can be a lesson video, a speech video, a job answering video and the like which are recorded and finished by a teacher in network remote online education.

the courseware operation instruction comprises operation data and time information corresponding to the operation data.

specifically, the server analyzes the teaching video by adopting an image analysis algorithm, and extracts at least one courseware operation instruction from the teaching video. The courseware operation instruction comprises operation data and time information corresponding to the operation data.

Step 002: and the server a stores the courseware operation instruction and the courseware data respectively.

and the server a stores the courseware operation instruction in a courseware operation instruction folder and stores the courseware data in a courseware data folder.

The courseware identifier can be understood as information which can be used for uniquely identifying the teaching courseware, and the courseware identifier can be id, package name, version number and the like of the courseware.

step 003: the user terminal 1 sends a data request for obtaining courseware data to the server a.

The courseware data generally refers to audio-visual data, read-write data and other data related to teaching courseware, the audio-visual data may be text data of courseware, audio data in courseware (for example, sound effect of a certain button and the like), animation data in courseware and the like, the read-write data refers to data which can be used by a user for inputting operation, wherein the inputting operation is completed in an interactive information input area provided by a certain page of courseware in the courseware, for example, a user can click characters, pictures and the like on an interface to input characters in the certain page of courseware.

Specifically, when detecting that the user selects an option of a teaching course through touching the user terminal screen with a finger, the user terminal 1 reads and executes a machine executable instruction corresponding to a control logic for starting the teaching course, and sends a data request for acquiring courseware data corresponding to the teaching course to the server a.

Step 004: and the server a responds to the data request and sends the courseware data to the user terminal.

Specifically, after receiving a data request for obtaining courseware data from a user terminal, a server analyzes the data request to obtain courseware identification corresponding to the courseware data after analysis, searches the courseware data corresponding to the courseware identification in a database based on the courseware identification, and after the courseware data is searched, the server sends the courseware data searched to the user terminal.

Step 005: after receiving the courseware data sent by the server a, the user terminal 1 displays the teaching courseware in the first display area of the current display interface.

The first display area can be understood as a display area used for displaying teaching courseware on a display interface of the user terminal.

step 006: the server a sends recorded and broadcast video data to the user terminal 1.

In the embodiment of the application, the recorded and played video data can be a lesson video, a lecture video, a work answering video and the like corresponding to the teaching courseware which are recorded and finished in the network remote online education.

Specifically, the server a may send at least one courseware operation instruction to the user terminal when the session time of the teaching courseware is reached, where the at least one courseware operation instruction is all courseware operation instructions included in the recorded and broadcast video.

Alternatively, the server a may sequentially send at least one courseware operation instruction to the user terminal 1 based on the time information.

Step 009: and the user terminal 1 displays the operation behavior corresponding to the operation data in the teaching courseware based on the time information.

Specifically, the user terminal 1 obtains the display duration of each page of courseware in the teaching courseware, and a time axis is formed by taking the display moment of the first page of courseware in the teaching courseware as a time starting point and according to the sequence of each page of courseware and the display duration. And then acquiring the position of the time information in the time axis, and acquiring courseware content indicated by the position in the teaching courseware. And displaying the operation behavior corresponding to the operation data at the courseware content, wherein the teaching courseware responds to the operation behavior.

In a possible implementation manner, when users on multiple user terminals simultaneously schedule recorded teaching courses at a certain time point, and/or multiple user terminals simultaneously acquire teaching data (teaching courseware, recorded and broadcast videos and the like) of the teaching courses from a server at the same time point or within a time period (5 minutes), the server can establish a network online classroom of the multiple user terminals, and establish network conversation connections for the multiple user terminals to provide network conversation functions among the users on the multiple user terminals, the multiple user terminals can complete network multi-conversation with the user terminals through chat boxes on a current display interface, and the network conversation can be a learning communication conversation, a question answering conversation and the like.

For example: as shown in fig. 3, when the user 1, the user 2, and the user 3 simultaneously obtain recorded and broadcasted videos and teaching courseware of the english teaching lessons from the server through their corresponding user terminals within a period of 5 minutes, the server establishes network session connections of the user 1, the user 2, and the user 3, and the user 1, the user 2, and the user 3 can communicate learning problems in a "chat room" of the current display interface through their respective user terminals, as shown in fig. 3, an interface diagram of the user 1, the user 2, and the user 3 communicating learning problems is shown.

in the embodiment of the application, a user terminal acquires courseware data, displays teaching courseware in a first display area of a current display interface based on the courseware data, and acquires at least one courseware operation instruction, wherein the courseware operation instruction comprises operation data and time information corresponding to the operation data, and operation behaviors corresponding to the operation data are displayed in the teaching courseware based on the time information. The operation behavior corresponding to the courseware operation instruction is synchronously displayed in the teaching courseware based on the time information, so that a teacher does not need to directly broadcast and explain the same courseware for many times, the teaching cost can be saved, the attention of students can be improved, and the teaching effect is enhanced.

In one embodiment, as shown in fig. 4, an online education method is specifically proposed, which can be implemented by means of a computer program and can be run on an online education device based on von neumann architecture. The computer program may be integrated into the application or may run as a separate tool-like application. For convenience of description, the on-line teaching apparatus is used as the user terminal.

specifically, the online teaching method comprises the following steps:

Step 101: courseware data are obtained, and teaching courseware is displayed in a first display area of a current display interface based on the courseware data.

the teaching courseware refers to a presentation used by a teacher for teaching, and the presentation is a file for content transmission and display, such as a slide document (PowerPoint, PPT), a Flash file and the like, generated by multimedia information such as characters, pictures, audio and the like and other elements. The teacher can better finish the teaching content through the teaching courseware. The courseware is typically stored in a courseware folder.

The first display area can be understood as a display area used for displaying teaching courseware on a display interface of the user terminal.

specifically, after detecting an input starting instruction of a user for a teaching course, a user terminal sends a courseware data acquisition request to a server, and after acquiring the courseware data, the user terminal decodes the courseware data to obtain a decoded teaching courseware, and then displays the courseware data in a first display area of a current user terminal display interface.

Optionally, the instruction for starting the input of the teaching course by the user may be completed through an external device, for example, the instruction for starting the teaching course input by the user through the teaching course on the display interface of the user terminal selected by the mouse connected to the user terminal; the user can input corresponding instructions through a keyboard or a touch pad connected with the user terminal; the instruction can be an instruction for starting the teaching courseware through voice input by the user (for example, the voice input starts a certain teaching course, etc.); the user can acquire a gesture control instruction through the camera to complete the operation of starting a specific teaching course, and can select options of the teaching course through a finger or an electromagnetic pen touch control user terminal screen.

for convenience of description of the embodiment of the present application, a detailed description will be specifically given by taking an option of selecting a teaching course through a finger touch on a screen of a user terminal as an example.

The user terminal may have a touch screen, and the touch screen may be a touch screen capable of implementing a single touch function, for example: capacitive touch screen, electromagnetic touch screen, can also be the touch-sensitive screen that can realize capacitive sensing, electromagnetic induction and infrared induction simultaneously. When a user touches the touch screen of the intelligent interaction panel through a finger, the capacitance parameter of the touch position changes, and the touch frame determines the touch position of the finger on the touch screen according to the change of the capacitance; or when the finger contacts the touch frame, the infrared receiving end is blocked to receive the infrared signal, and the touch frame determines the touch position of the finger according to the blocked infrared signal. After detecting the position of the touch position-teaching course option, the user terminal sends a data request for acquiring courseware data corresponding to the teaching course to the server by reading and executing a machine executable instruction corresponding to a control logic for starting the teaching course, the server responds to the request, searches courseware data corresponding to the teaching course, sends the courseware data to the user terminal, and after receiving the courseware data, the user terminal analyzes and processes the courseware data to obtain teaching courseware after analysis and processing, and then displays the courseware data in a first display area of a display interface of the current user terminal.

In a possible implementation manner, a user may input a reservation instruction for the teaching course on a display interface of a user terminal, where the reservation instruction is used to reserve the teaching course at a specific time point, and the user terminal may obtain teaching data (teaching courseware, recorded and broadcast video, etc.) corresponding to the teaching course in real time from a server based on the reservation instruction, may obtain the teaching data corresponding to the teaching course from the server at the specific time point based on the reservation instruction, and so on.

step 102: the method comprises the steps of obtaining at least one courseware operation instruction, wherein the courseware operation instruction comprises operation data and time information corresponding to the operation data.

the operation data comprises courseware operation data of teaching courseware and interaction operation data of students, and the courseware operation data comprises at least one of click operation data, drag operation data, annotation operation data and page turning operation data.

The operation data may be understood as operation data corresponding to an operation behavior of an operator on the teaching courseware generated by the server during recording the recorded and broadcast video corresponding to the teaching courseware, where the operation data corresponds to a corresponding operation behavior, for example, an operation behavior corresponding to click operation data — click operation.

the click operation refers to the click of a teacher on a click object (picture, text, icon, etc.) in a certain page of presentation of a teaching courseware, the click operation can be a single click on a certain icon or text to view details, a double click on a certain icon or text to enlarge, etc., when the click operation is performed by the teacher through an external device such as a mouse, the click operation further comprises left click, left double click, middle double click, right double click, etc.

The dragging operation refers to dragging operation that after a teacher selects and drags an object (a picture, a text, an icon and the like) in a certain page of presentation of a teaching courseware, fingers do not leave a screen, and in the process of dragging the fingers, the dragged object moves along with the movement of the fingers. It should be noted that the dragging operation may be performed by an external device such as a mouse, an electronic pointer, a laser pointer, etc.

the annotation operation refers to an operation of a teacher selecting an annotation object (a picture, a text, an icon, or the like) in a certain page of presentation of a teaching courseware and then marking or annotating the annotation object, for example, marking a certain sentence of characters with a triangular symbol.

the page turning operation refers to a sliding operation of a teacher on a certain page of the presentation of the teaching courseware, and the sliding operation includes page turning of the whole page in the horizontal direction, continuous rolling page turning in the vertical direction, and the like.

The time information includes, but is not limited to, an operation start time indicated by the operation data, an operation end time indicated by the operation data, an operation duration indicated by the operation data, and the like. For example, the annotating operation indicated by the annotating operation data, the completion of the annotating operation corresponds to the annotating operation starting time, the annotating operation ending time, the annotating operation duration, and the like.

specifically, after detecting an input opening instruction of a user for a teaching course, a user terminal initiates an acquisition request of a courseware operation instruction corresponding to the teaching courseware of the teaching course to a server, the server responds to the acquisition request, searches the courseware operation instruction corresponding to the teaching courseware in a local storage space, when all the courseware operation instructions corresponding to the teaching course are found, the server sends all the courseware operation instructions to the user terminal, and at the moment, the user terminal acquires all the courseware operation instructions. The courseware operation instruction comprises operation data of teachers on teaching courseware and time information corresponding to the operation data.

Optionally, the user terminal may obtain the at least one courseware operation instruction from the server in batch based on the communication connection quality (e.g., uplink and downlink rates, frame loss rate, time delay, etc.) between the current user terminal and the server; the user terminal may obtain the at least one courseware operation instruction from the server in batches based on the load status (CPU load, background thread, resource pool occupancy, etc.) of the current user terminal.

It should be noted that, in this embodiment, the order of obtaining the courseware data and obtaining the at least one courseware operation instruction by the user terminal is not sequential, and may be obtaining the courseware data and obtaining the at least one courseware operation instruction simultaneously.

Step 103: and displaying the operation behavior corresponding to the operation data in the teaching courseware based on the time information.

the operation behavior may be understood as displaying a corresponding operation behavior on the teaching courseware based on the time information corresponding to the operation data, where the operation behavior includes, but is not limited to, at least one of a click operation behavior, a drag operation behavior, an annotation operation behavior, a page turning operation behavior, and the like. For example: at the time point of '02: 00' of the teaching courseware playing, the notes of a teacher for a certain knowledge point are added into the teaching courseware to show the notes for the knowledge point, and the marks (triangle marks, pentagram marks and the like) of the teacher for a certain important concept are added into the corresponding positions of the teaching courseware.

specifically, after the user terminal obtains at least one courseware operation instruction, each operation instruction in the at least one courseware operation instruction is analyzed to obtain operation data of the courseware operation instruction and time information corresponding to the operation data, and the operation data and the time information are based on teaching courseware corresponding to the teaching courses. And acquiring at least one base frequency data of the operation data, and forcibly aligning each base frequency data in the teaching operation information with a certain courseware in the teaching courseware indicated by the time information by adopting a forced alignment technology based on the time information. Thus, the correspondence between the courseware content (text, paragraph, picture, icon, button, etc.) of the certain course in the teaching courseware and each fundamental frequency data in the teaching operation data is determined, and the correspondence may be understood as that after forced alignment, the operation information of the operation behavior on the course of the certain time node or time period may be obtained, for example: when the teaching courseware is 30 seconds, the teacher makes a page turning operation behavior on the first courseware, and then the operation information (such as animation for turning pages, triggering coordinates for page turning operation and the like) of each fundamental frequency data corresponding to the page turning operation behavior on the first courseware can be obtained through the forced alignment.

And when the time point and/or the time period indicated by the time information is reached by playing the teaching courseware, the user terminal loads the operation data indicated by the time information on the teaching courseware based on the corresponding relation, so that the operation behavior corresponding to the operation data is displayed in the teaching courseware.

The fundamental frequency data can be understood as the smallest information unit of the operation data, for example: when the teaching courseware is timed by time milliseconds, one piece of fundamental frequency data represents the annotating operation data within 1 millisecond, so that the annotating operation can be completed within 3 milliseconds, and the annotating operation data consists of the fundamental frequency data corresponding to 3 milliseconds.

in a feasible implementation manner, after the user terminal obtains at least one courseware operation instruction corresponding to a plurality of time points and/or time periods, in order to avoid a delay in response to an operation behavior corresponding to the operation data when the operation data indicated by the time information is loaded based on the time information, the user terminal may display the operation behaviors corresponding to the plurality of operation data in the teaching courseware in a pre-loading manner.

in a feasible implementation manner, in actual teaching, usually, by displaying the operation behavior manner corresponding to the operation data in the teaching courseware based on the time information, all knowledge points appearing in teaching cannot be covered due to the limitation of objective factors such as teaching video time or teaching courseware space, and based on this, the user terminal can add a knowledge point viewing function to the teaching courseware during the online teaching process. The important knowledge points in the teaching courseware are labeled, the important knowledge points can be knowledge points mentioned by teachers in teaching videos, knowledge points related to the teaching courseware and the like, when a certain page of slide played in the synthesized courseware relates to the important knowledge points, the labeling information of the knowledge points is displayed to a user based on preset display rules, and the preset prompt rules include but are not limited to displaying the labeling information of the knowledge points in the forms of hyperlinks, pop-up windows, display bars, picture-in-picture, suspension side columns and the like.

For example, in an english teaching scenario, a student learns english words through a user terminal-smart tablet, a display interface of the smart tablet may be as shown in fig. 5, a teaching courseware area for playing teaching courseware and a teaching video area for playing teaching video are shown in fig. 5, the teaching courseware and the teaching video are played synchronously, when the user learns a "fruit word" teaching link as shown in fig. 5, the interface displayed by the teaching courseware area is a "fruit word" slide, the slide relates to various fruits, when the user does not understand the "pear" word, the user may select the "pear" word on the display interface through a finger, the user terminal-smart tablet recognizes an input instruction of the user, and displays the labeled information of the "pear" in a display of a pop-up window, that is, the pop-up window interface as shown in fig. 5, the popup displays the marked information of the part of speech, paraphrase, complex number, example sentence and the like of the "peer".

In the embodiment of the application, a user terminal acquires courseware data, displays teaching courseware in a first display area of a current display interface based on the courseware data, and acquires at least one courseware operation instruction, wherein the courseware operation instruction comprises operation data and time information corresponding to the operation data, and operation behaviors corresponding to the operation data are displayed in the teaching courseware based on the time information. The operation behavior corresponding to the courseware operation instruction is synchronously displayed in the teaching courseware based on the time information, so that a teacher does not need to directly broadcast and explain the same courseware for many times, the teaching cost can be saved, the attention of students can be improved, and the teaching effect is enhanced.

Please refer to fig. 6, which is a flowchart illustrating an online teaching method according to an embodiment of the present disclosure. The embodiment is exemplified by applying the online teaching method to the user terminal. The online teaching method can comprise the following steps:

Step 201: courseware data are obtained, and teaching courseware is displayed in a first display area of a current display interface based on the courseware data.

Specifically, refer to step 101, which is not described herein again.

step 202: and receiving recorded and broadcast video data, and displaying a recorded and broadcast video in a second display area of the current display interface based on the recorded and broadcast video data, wherein the recorded and broadcast video comprises actions, expressions and/or words corresponding to the operation behaviors.

The recorded and broadcast video data can be understood as teaching video data containing teaching of teachers and/or students, namely teaching video data related to lectures of teachers, and the recorded and broadcast video data can be video files which are already recorded and can also be video files which are recorded by teachers in the course of teaching in classes. In the embodiment of the application, the recorded and broadcast video data may be the video data of lessons, lecture video data, job answering video data, and the like recorded and completed in the network remote online education.

The second area can be understood as an area for playing recorded and played videos on a display interface of the user terminal, and the first display area for playing teaching courseware on the display interface of the user terminal is not overlapped with the second display area. For example, as shown in fig. 7, which is an interface of a user terminal teaching course, the first display area may be an a area in the figure, and is used for playing a teaching courseware. The second display area may be an area B in the figure, and is used for playing recorded and played video.

Specifically, the user terminal receives recorded broadcast video data sent by the server, decodes the recorded broadcast video data, plays the recorded broadcast video in the second display area, displays the first page of courseware of the teaching courseware in the first display area of the display interface, and plays the teaching courseware based on the current display time of the first page of courseware in the recorded broadcast video when the user terminal detects that the recorded broadcast video is played to the current display time of the first page of courseware, so as to achieve the effect of synchronous playing of the teaching courseware and the recorded broadcast video.

It should be noted that, the display area of the teaching courseware in the display interface corresponding to the recorded and broadcast video may not be fixed.

in the teaching process, the user can freely switch the display area of the synthesized courseware corresponding to the recorded and broadcast video, for example, as shown in fig. 7, the user can touch a switch button of the current interface with a finger to select to switch the display area of the teaching courseware and the recorded and broadcast video. The switching can also be based on the detection of each teaching link in the recorded and broadcast video by the user terminal, so as to determine the display area corresponding to the current teaching courseware and the recorded and broadcast video. Such as:

In a first scenario, a teacher annotates the teaching courseware, and at the moment, the importance of the display of the teaching courseware is considered to be higher, the server displays the teaching courseware in an area A with the largest display area, and displays the teaching video in an area B of the display area.

And in a second scenario, the teacher is teaching how to pronounce the words, and at the moment, the importance of the recorded and broadcast video display is considered to be higher, so that the teaching video is displayed in an area A with the largest display area, and the teaching courseware is displayed in an area B of the display area.

Step 203: and receiving at least one courseware operation instruction sent by the server when the class time of the teaching courseware is reached, wherein the at least one courseware operation instruction is all courseware operation instructions corresponding to the teaching courseware. The courseware operation instruction comprises operation data and time information corresponding to the operation data.

specifically, a user sends a teaching courseware reservation request for reserving a certain class time to a server through a user terminal, after the server receives the reservation request, when the class time of the teaching courseware is reached, all courseware operation instructions corresponding to the teaching courseware are searched in a local storage space, when all the courseware operation instructions corresponding to the teaching courseware are searched, the server sends all the courseware operation instructions to the user terminal, and at the moment, the user terminal obtains all the courseware operation instructions. The courseware operation instruction comprises operation data of teachers on teaching courseware and time information corresponding to the operation data.

In a possible implementation manner, the user sends a teaching courseware reservation request for reserving a certain class time to the server through the user terminal, and the server receives the reservation request, namely, the reservation is successful. In practical application, the time of the user terminal sending the reservation request and the class time of the teaching courseware are separated by a period of time, a user on the user terminal may get off the line after the reservation is successful, the off-line can be understood as the disconnection of communication with the server, and when the disconnection of communication, the user terminal cannot receive the operation instruction sent by the server.

When the server reaches the class time of the teaching courseware, a heartbeat packet is sent to the user terminal, the heartbeat packet is used for detecting whether the communication connection is recovered to a normal connection state or not, namely whether the user terminal is on-line or not, when a user on the user terminal is on-line, the user terminal receives the heartbeat packet and sends response information fed back by the heartbeat packet to the server, so that the server sends all courseware operation instructions corresponding to the teaching courseware after receiving the response information. At this time, the user terminal receives all courseware operation instructions corresponding to the teaching courseware sent by the server.

It should be noted that, in this embodiment, the order of acquiring the courseware data, receiving the recorded and broadcast video data, and acquiring the at least one courseware operation instruction by the user terminal is not sequential, and may be the same time of acquiring the courseware data, receiving the recorded and broadcast video data, and acquiring the at least one courseware operation instruction.

Step 204: and receiving at least one courseware operation instruction which is sequentially sent by the server according to the time information, wherein the courseware operation instruction comprises operation data and time information corresponding to the operation data.

Or receiving courseware operation instructions corresponding to the teaching courseware in a period of time and sent by the server

specifically, a user sends a teaching courseware reservation request for reserving a certain class time to a server through a user terminal, the server receives the reservation request, searches all courseware operation instructions corresponding to the teaching courseware in a local storage space when the class time of the teaching courseware is reached, acquires time information contained in each operation instruction in all the courseware operation instructions when all the courseware operation instructions corresponding to the teaching courseware are searched, and sends the courseware operation instructions matched with the current teaching courseware display time to the user terminal in sequence.

In this embodiment, the time matching with the current teaching course display time may be understood as setting a time difference threshold, and when the time difference between the time corresponding to the time information included in the operation instruction and the current teaching course display time is smaller than the time difference threshold, the time is matched with the current time.

For example: there are 3 operation commands corresponding to a certain teaching courseware, and the time corresponding to the time information contained in the 3 operation commands is t1, t2 and t3 respectively. Specifically, the method comprises the following steps: t 1: "01: 10 ", t 2: "02: 11 ", t 3: "03: 12', current teaching courseware display time t: "01: 01 ", the time differences of t1, t2, t3 and t are respectively: 19. 70, 131, the time difference threshold value is 20. And at the moment, the time difference value between the t1 time and the current teaching courseware display time is smaller than the time difference threshold value, and then the operation signaling corresponding to the t1 time is sent to the user terminal.

Optionally, the user terminal may receive a courseware operating instruction corresponding to the teaching courseware sent by the server within a period of time, for example: the user terminal can send an acquisition request of courseware operation instructions corresponding to the teaching courseware within a period of time to the server based on the communication connection quality (such as uplink and downlink rates, frame loss rate, time delay and the like) and the load state (such as CPU load, background thread, resource pool occupancy rate and the like) of the current user terminal and the server, and the server sends the courseware operation instructions corresponding to the teaching courseware within a period of time to the user terminal based on the acquisition request.

Step 205: and determining the position of the time information in the time axis according to the sequence of the courseware on each page and the time axis mapped by the display duration by taking the initial display time of the first page of courseware in the teaching courseware as a time starting point.

The initial display time of the first page of courseware can be understood as the time when the user terminal starts to display the first page of courseware in the teaching courseware on the display interface.

the courseware comprises at least one page of courseware, the courseware is provided with a page number, each page of courseware of the teaching courseware is identified by the page number, and the sequence of each page of courseware can be understood as the sequence of the page number of each page of courseware.

Specifically, after the user terminal receives the courseware, the page number label of each courseware in the courseware and the display time of each courseware are obtained, the display time of the courseware with the page number label of 1 corresponding to the display interface of the user terminal is taken as the time starting point, the display time of each courseware is taken as the time interval on the time axis, and the time axis of the courseware is formed according to the sequence of each courseware.

For example, the teaching courseware has 5 pages, and the display time, i.e. the display duration, of each page of courseware is respectively: in the form shown in fig. 8, the schematic diagram of the time axis formed by the current display time of the first-page courseware in the teaching courseware as the time starting point, according to the sequence of the courseware of each page and the display time length, in fig. 8, the initial time of the first-page courseware is "00: 00 'and the display time of the first courseware is 1 minute, the starting time of the second page is' 01: 00' and so on, and forming a time axis of the teaching courseware.

step 206: and displaying the operation behaviors on courseware display contents indicated by the positions, and responding to the teaching courseware based on the operation behaviors.

specifically, the user terminal obtains at least one fundamental frequency data contained in the operation data, the fundamental frequency data can be understood as the minimum information unit of the operation data, the time point and/or the time period corresponding to each fundamental frequency data in the time information is obtained, the position of the time point and/or the time period corresponding to each fundamental frequency data in the teaching courseware time axis is obtained, acquiring courseware with corresponding page numbers indicated by the positions in the teaching courseware, forcibly aligning each fundamental frequency data contained in the operation data with courseware with corresponding page numbers corresponding to the fundamental frequency data by adopting a forced alignment technology, determining a corresponding relation between each fundamental frequency data and courseware contents (characters, paragraphs, pictures, icons, buttons and the like) contained in the courseware with corresponding page numbers, and acquiring courseware contents indicated by each fundamental frequency data in the courseware with corresponding page numbers based on the corresponding relation.

Specifically, the user terminal loads each base frequency data in the operation data at the courseware content after acquiring the courseware content indicated by the position in the teaching courseware according to the position of the time information in the time axis, so as to respond to the operation behavior corresponding to the operation data in the teaching courseware.

For example, the user terminal needs to respond to an operation behavior-annotation operation corresponding to certain annotation operation data in the teaching courseware. The annotation operation information is composed of 3 pieces of fundamental frequency data, and when the fundamental frequency data is measured in time seconds, one piece of fundamental frequency data represents the operation information represented in 1 second of time, it can be understood that 3 seconds are required for completing one annotation operation.

The corresponding display time of 3 fundamental frequency data forming certain annotation operation data on the time axis of the teaching courseware is as follows: t1, t2, t 3. Specifically, the method comprises the following steps: t 1: "01: 10 ", t 2: "01: 11 ", t 3: "01: 12 ", the corresponding diagram of the time axis can be seen in fig. 9 a. Loading 3 fundamental frequency data of the annotation operation data on the text content of the second-page courseware, wherein the annotation operation corresponding to the annotation operation data is to add annotation content to the text content "wann" of the second-page courseware in the teaching courseware, as shown in fig. 9b, fig. 9b is an interface schematic diagram of responding to the annotation operation corresponding to the annotation data on the second-page courseware, and 3s are required for completing annotation of the text in the interface schematic diagram, where the 3 fundamental frequency data of the annotation operation data are respectively: the fundamental frequency data 1 corresponds to a waning circle prompt of characters of the second page courseware, the fundamental frequency data 2 corresponds to a comment frame for displaying the characters of the second page courseware, and the fundamental frequency data 3 corresponds to comment characters displayed in the comment frame.

please refer to fig. 10, which is a flowchart illustrating an online teaching method according to an embodiment of the present disclosure. The embodiment is exemplified by applying the online teaching method to the server. The online teaching method can comprise the following steps:
