Alternative embodiments of the present disclosure are described in detail below with reference to the drawings.
The first embodiment provided by the present disclosure, namely, an embodiment of an interaction method for live teaching.
The embodiments of the present disclosure are described in detail below with reference to fig. 2.
Step S201, obtaining teaching voice information.
The teaching voice information is the voice information of teaching teachers in live classroom. Voice information of teaching can be collected through a microphone in a live classroom; video information of the lecture can be collected through the video camera, and voice information is separated from the video information.
Step S202, semantic analysis is carried out on the teaching voice information, and key information related to teaching key points is obtained.
Generally, a semantic analysis model is adopted to perform semantic analysis on the teaching voice information so as to determine key information related to teaching emphasis and the teaching voice information. The semantic analysis model can be obtained based on previous historical lecture voice information, for example, the semantic analysis model is trained by taking the historical lecture voice information as a training sample. The present embodiment does not describe in detail the process of performing semantic analysis on the lecture voice information according to the semantic analysis model, and may refer to various implementation manners in the prior art.
In a teaching lesson, a teaching teacher often divides the teaching content into a plurality of different levels for teaching. The teaching contents of different levels have different importance in teaching courses. One of the bases for dividing the teaching focus is whether students in class can easily understand. Based on this, the teaching focus can be divided into a plurality of different grades. The embodiment of the disclosure determines the lecture listening effect of a student according to the feedback of the student terminal on the key information.
The key information is preset information, wherein key contents of teaching key points are summarized. The power is the work done by the object in unit time, which is a key word segment; alternatively, "power" and "time unit" are two keywords.
In a live teaching classroom, a teaching teacher can explain for many times aiming at the same important teaching content, so that key information can appear for many times.
Step S203, obtaining feedback information related to the lecture listening effect from each student terminal based on the key information, and adding the feedback information to a feedback information queue of the corresponding student terminal.
The student terminals are terminals for logging in the live teaching classroom by student identities. The embodiment of the disclosure establishes a feedback information queue for each student terminal, and each feedback information queue comprises feedback information.
Specifically, the obtaining feedback information related to the lecture listening effect from each student terminal based on the key information includes the following steps:
and step S203-1, generating survey information related to the lecture listening effect based on the key information, and transmitting the survey information to each student terminal.
In the embodiment of the disclosure, each time the key information is acquired, the survey information for the key information is generated and transmitted to each student terminal. The purpose is to know the mastering condition of teaching contents related to key information by students who attend to the class before each student terminal.
In one embodiment, the generating of the survey information for the lecture attending effect based on the key information includes the following specific steps:
step S203-1-1, generating question information aiming at the effect of listening to lessons and a plurality of candidate first effect information aiming at the question information based on the key information.
And step S203-1-2, generating the survey information based on the question information and the first effect information.
For example, the key information is "power means work done by the object in unit time", and the question generation information is "do you understand" power means work done by the object in unit time? "; generating three candidate first effect information aiming at the question information: "understand", "generally" and "not understand".
And after the investigation information is transmitted to each student terminal, the investigation information is displayed in real time in a user interface of the student terminal so as to feed back the mastering condition of the students on the teaching content related to the key information in time.
And step S203-2, obtaining feedback information of each student terminal responding to the investigation information.
For example, continuing the above example, after the survey information is displayed in real time in the user interface of the student terminal, the effect information selected by the student in the terminal is "general", indicating that the student in front of the terminal has not completely understood the teaching focus indicated by the key information; after selecting 'general', the student terminal generates feedback information corresponding to the selection result and transmits the feedback information to the terminal transmitting the investigation information.
And step S204, analyzing each feedback information queue, and determining the teaching effect evaluation of the corresponding student terminal.
And if a plurality of key information related to important teaching exists in a live teaching classroom, the feedback information queue comprises a plurality of feedback information. According to the embodiment of the disclosure, the teaching effect of the student terminal corresponding to each feedback information queue can be obtained by analyzing the feedback information queues.
In one embodiment, the analyzing each feedback information queue to determine the lecture listening effect evaluation of the corresponding student terminal includes the following steps:
and step S204-1, acquiring a preset effect value and a preset weight value corresponding to the feedback information according to each feedback information.
And the effect value is used for indicating the lecture listening effect of the student. For example, the preset effect value and the candidate first effect information are in a one-to-one correspondence relationship; for example, the first effect information of the three candidates is: "understand", "generally" and "not understand"; the corresponding effect values are respectively: 3. 2 and 1; the effect values corresponding to the candidate effect information may also be made different according to the importance degree of the key information, for example, the effect values are: 5. 3 and 1.
Optionally, the feedback information further includes second effect information, where the second effect information is effect information determined by the student terminal from the first effect information.
Correspondingly, the method for acquiring the preset effect value corresponding to the feedback information according to the feedback information comprises the following steps:
and step S204-1a, acquiring a preset effect value according to the second effect information.
For example, the first effect information of the three candidates is: "understand", "generally" and "not understand"; the corresponding effect values are respectively: 3. 2 and 1; when the student selects "general" in the first effect information as the second effect information at the student terminal, the corresponding effect value is 2.
As shown in fig. 3, the user interface of the student terminal in the embodiment of the present disclosure is used to display a layout including a presenter display area and a plurality of student display areas; each student display area side has three buttons, which respectively represent "understand", "general" and "not understand", and a student can select any one of the buttons according to the self lecture listening situation.
And the weight value is used for indicating the importance of the teaching key in the live teaching course in the same hall.
In particular, the feedback information comprises a unique value characterizing the critical information. The unique value is used to indicate a response object of the feedback information. The present embodiment does not describe in detail the process of obtaining the unique value of the key information, and can be implemented by referring to various implementations in the prior art. For example, continuing the above example, the key information is "power is the work done by the object in unit time", the unique value is 96, and the question information further includes the unique value 96; when the effect information selected by the student in the terminal is "general", the feedback information of the key information includes the unique value 96 and the effect information "general".
Correspondingly, the obtaining of the preset weight value corresponding to the feedback information according to the feedback information includes the following steps:
and step S204-1b-1, acquiring the unique value.
For example, continuing the above example, the unique value is 96.
And S204-1b-2, acquiring a preset weight value based on the unique value.
The unique value and the preset weight value can be in a one-to-one mapping relationship or a one-to-many relationship. Further, the obtaining of the preset weight value based on the unique value includes the following steps:
and step S204-1b-2-1, acquiring a first weight value and a weight value sequence from a preset weight data set based on the unique value.
The first weight value is used to indicate the percentage of the importance of the key information in the teaching focus, and is usually set by the teaching teacher according to the importance of the teaching content, for example, according to the importance indicated in the class. And the weight value under each serial number in the weight value sequence is used for indicating the percentage of the influence degree of the key information corresponding to the unique value on the lecture listening effect each time.
For example, the unique value is 96, the first weight value is 50%, the weight value sequence is: 20% and 45%.
And step S204-1b-2-2, counting the occurrence times of the unique value before the arrangement position of the feedback information in the feedback information queue.
For example, continuing with the above example, in the feedback information queue, the feedback information at the first queue position is: 96 and "normal"; the feedback information of the second arrangement position is: 82 and "understand"; the feedback information of the third arrangement position is: 96 and "understand"; the number of occurrences before the first arrangement position 96 is 0, the number of occurrences before the second arrangement position 82 is 0, and the number of occurrences before the third arrangement position 96 is 1.
And step S204-1b-2-3, determining the occurrence number as the sequence number of the arrangement positions in the weight value sequence.
And S204-1b-2-4, acquiring a second weight value corresponding to the sequence number of the arrangement position from the weight value sequence.
For example, continuing the above example, if the unique value is 96, and the number of occurrences of 96 before the first arrangement position in the feedback information queue is 0, the arrangement position number in the weight value sequence is 0, and the weight value of the arrangement position number in the weight value sequence is 20%; if the number of occurrences before the third arrangement position 96 is 1, the arrangement position number in the weight value sequence is 1, and the weight value of the arrangement position number in the weight value sequence is 45%.
And S204-2, determining a feedback score corresponding to the feedback information based on the preset effect value and the preset weight value of each feedback information.
Specifically, a product of a preset effect value and a preset weight value is calculated, and the feedback score is obtained.
For example, continuing with the above example, the product of the first weight value, the second weight value and the preset effect value is calculated to obtain the feedback score; for example, in the feedback information queue, the feedback information at the first arrangement position is: 96 and "general", the preset effect value is 2, the first weight value is 50%, the second weight value is 20%, and the feedback score is 0.2 which is the product of the preset effect value, the first weight value and the second weight value; the feedback information of the third arrangement position is: 96 and "understand", the preset effect value is 3, the first weight value is 50%, the second weight value is 45%, and the feedback score is 0.675 which is the product of the preset effect value, the first weight value and the second weight value.
And step S204-3, counting all feedback scores in each feedback information queue, and determining a comprehensive evaluation value of the lecture attending effect evaluation representation.
The comprehensive evaluation value is the teaching effect evaluation of the student terminal corresponding to each feedback information queue. For example, the sum of all feedback scores in the feedback information queue is calculated, and the value is the comprehensive evaluation value.
The larger the sum of the feedback scores is, the better the lesson listening effect is. The teaching teacher can master the teaching effect of the current students in teaching in real time through the feedback value, and continuously adjust the teaching strategy (including teaching content, teaching rhythm, interactive skills, and the like) according to the teaching effect.
According to the teaching method and the teaching device, key information relevant to teaching key points is obtained through teaching voice information, then feedback information relevant to the teaching effect is obtained from each student terminal through the key information, and then the teaching effect evaluation corresponding to the student terminal is determined through analyzing a series of feedback information. The teaching effect evaluation can be displayed in a panoramic intelligent blackboard of a teacher terminal in real time so that a teaching teacher can know the teaching effect of students in front of each student terminal and can analyze the teaching effect of each student after class. If the evaluation statistics of the lecture listening effect of the students in front of each student terminal is integrated, the teaching teacher can be assisted to know the lecture listening effect of the whole students in the live teaching classroom. Thereby helping the teaching teacher to improve the teaching method in time.
