In one or more embodiments, a kind of interactive approach of online class by student side device as shown in Figure 1, executed
Interactive approach shown in Fig. 1, specific as follows:
Step S100, the feedback command of user's input is received.
Wherein, the feedback command of user's input is for indicating that the user broadcasts according to the first multimedia of curricula
Put the feedback that branch makes.
In one or more embodiments, the user is student, and student side device crosses touch screen, mouse, keyboard etc. extremely
A kind of few input equipment receives the feedback command of student's input, in one or more embodiments, described according to more than first matchmaker
It includes audible feedback or movement feedback that body, which plays the feedback that branch makes, for example, sound feedback is student with reading, movement is fed back to
It is hand-written.
In one or more embodiments, the corresponding content of first multimedia branch includes teaching courseware and religion
Video is learned, in the display interface display of student side device, the teaching courseware is shown together with instructional video rendering,
One complete curricula can be as shown in Fig. 2, include introduction, professor's content 1 to professor content n and conclusion, wherein
The shown factor includes INTRODUCTION OF THE COURSE STRUCTURE, scene introduction and story starter etc., includes professor part and practice portion in shown professor's content 1
Point, each professor part is designed with different multimedia branches, in one or more embodiments, the practice partially with
The professor part is identical, also is provided with different multimedia branches, is referred to as practice branch, and the present invention does not do it
It limits.The corresponding content of each multimedia branch includes teaching courseware and instructional video, or practice courseware and practice
Video.
Step S101, the feedback command inputted according to the user determines the corresponding opinion rating of the feedback.
In one or more embodiments, specifically, sending the feedback command that the user inputs to server;Receive institute
State the corresponding opinion rating of the feedback of server transmission, wherein the corresponding opinion rating of the feedback is the server
It is calculated according to the feedback command of user input.For example, sound feedback is fed back to according to student, to student with reading to send out
The matching degree of sound and standard pronunciation is judged that using matching degree as evaluation parameter, i.e. matching degree is higher, and evaluation parameter is higher,
Opinion rating is higher, it is assumed that and opinion rating is divided into three, respectively include: high praise grade, middle opinion rating and lower assessment valence etc.
Grade, different opinion ratings correspond to different evaluation parameter ranges, specific as shown in Figure 3.
Step S102, the second multimedia branch of the corresponding curricula is determined according to the opinion rating.
In one or more embodiments, as shown in figure 3 above, different opinion ratings corresponds to the second different multimedias and broadcasts
Put branch, it is assumed that the first multimedia branch is rendered together by teaching courseware 1 and instructional video 1, high praise grade
Corresponding second multimedia branch is rendered together by teaching courseware 2 and instructional video 2, and middle opinion rating is corresponding
Second multimedia branch is rendered together by teaching courseware 3 and instructional video 3, low opinion rating corresponding more than second
Media play branch is rendered together by teaching courseware 4 and instructional video 4;In one or more embodiments, in student
After having learnt the second multimedia branch being made of teaching courseware 2 and instructional video 2, it can carry out in next professor
Hold, alternatively, carrying out evaluate next time after, into next multimedia branch;In one or more embodiments, in student
After having learnt the second multimedia branch being made of teaching courseware 3 and instructional video 3, in teaching courseware 3 and instructional video 3
In the mistake of student is corrected after, carry out next professor content and give, alternatively, entrance is next after carrying out evaluation next time
A multimedia branch;In one or more embodiments, learnt to be made of teaching courseware 4 and instructional video 4 in student
The second multimedia branch after, in teaching courseware 4 and instructional video 4 to the content of teaching courseware 1 and instructional video 1 into
Row explanation and correction again evaluate the feedback command of the input of student after professor completes once, specific as shown in Figure 3.
Step S103, the second multimedia branch content acquisition instruction is sent, wherein second multimedia point
Branch content acquisition instruction is for obtaining the corresponding content of second multimedia branch.
In one or more embodiments, corresponding content is obtained according to the opinion rating determined in step S102, for example,
Teaching courseware 2 and instructional video 2 are obtained according to high praise grade, teaching courseware 3 and instructional video are obtained according to middle opinion rating
3, teaching courseware 4 and instructional video 4 are obtained according to low opinion rating.
Step S104, the corresponding content of second multimedia branch is received.
Step S105, the corresponding content of display second multimedia branch.
In the embodiment of the present invention, the feedback command of user's input is received first, wherein the feedback command of user's input
The feedback made for indicating the user according to the first multimedia branch of curricula, it is then defeated according to the user
The feedback command entered determines the corresponding opinion rating of the feedback, determines the corresponding religion then according to the opinion rating
The the second multimedia branch for learning course, then sends the second multimedia branch content acquisition instruction, wherein described the
Then two multimedia branch content acquisition instructions are received for obtaining the corresponding content of second multimedia branch
The corresponding content of second multimedia branch finally shows the corresponding content of second multimedia branch.It is logical
The above method is crossed, according to the feedback command that different user inputs, determines the corresponding different evaluation grade of different feedback commands, according to
Different evaluation grade determines the second multimedia branch of corresponding curricula, the content root of the second multimedia branch
The different from according to the difference of opinion rating makes each user according to obtaining itself suitable teaching the case where itself
Journey selects corresponding multimedia branch to impart knowledge to students that is, according to the demand of different user in curricula, meets
The demand of user individual growth.
It in one or more embodiments, further include a kind of interactive approach of online class as shown in figure 4, in step S105
