Example 4
In the method for counting the number of the hands, the execution main body is a server. The server may interact with the hands-raising statistics apparatus to determine students whose hands are raising questions on the online class.
In order to perform online course teaching, the server needs to interact with the student clients used by the students.
Specifically, the process of the server interacting with the client end used by the student comprises the following steps: the student can use the student to log in the server when carrying out online teaching, the server demonstrates the name of the course that can learn at present for the student through logging in the interface, the student selects the name of the course that need carry out the study from the name of the course that can learn at present through the client, after the server acquires the name of the course that the student selected, demonstrate the online video of the mr who teaches this course for the student, make the student obtain the online video of the mr who teaches this course through the server, and carry out course study under the online video's of mr guidance.
When a student has a question about teaching contents of a teacher, the student inputs question contents on a question bar arranged in a window of an online classroom of a client for the student, and after selecting a question button arranged beside the question bar, the client for the student sends the question contents input by the student to a question-raising statistic device, so that the question-raising statistic device can generate a question request according to the question contents input by the student.
The questioning content of the students is the questions the students ask to teachers.
Similarly, the server may also interact with a teacher-client used by a teacher in order for the teacher to teach the student online.
Specifically, the process of the server interacting with the teacher client used by the teacher includes: the teacher logs in the server through the teacher client, the server can determine the names of courses which can be taught by the teacher currently from the stored teaching list according to the user identification and the current time used when the teacher logs in after the teacher logs in, so as to obtain the names of the courses which can be taught by the teacher currently, wherein the teaching list comprises: the corresponding relation of the teaching time, the user identification of the teacher and the name of the teacher teaching course; acquiring images of a class in which a teacher is located according to the teacher client, generating a video link of the online class according to the images, and associating the generated video link of the online class with the name of a teacher teaching course; and finally, displaying the name of the teacher teaching course on a login interface displayed to the student by the server. When the student selects the name of a teacher teaching course on a login interface displayed by the server through the student client, the server displays the online video corresponding to the online classroom video link associated with the name of the teacher teaching course to the student.
The client for students may be an Application (APP) installed on a mobile terminal used by the students.
The teacher client may be an APP for teaching installed on the mobile terminal used by the teacher.
When a student selects the name of a learning course, the server performs incremental operation on the number of the lessons selected by the student, so that the number of the lessons of each current learning course is counted. And then acquiring the student identification of the student logging in the server, and associating the student identification of the student with the name of the teacher teaching course of the course selected by the student to learn, so that the server not only knows the number of people on class of each online course, but also can know which students are on class in each online course.
Referring to a flow chart of a method for counting the number of hands holding people shown in fig. 4, the method for counting the number of hands holding people according to the embodiment includes:
In the step 400, the server may query out the name of the teacher teaching course associated with the student identifier of the student according to the student identifier of the student carried in the question request, so that the teacher giving the on-line course of the student can be determined according to the name of the teacher teaching course associated with the student identifier of the student, that is, the server determines the teacher who needs to answer the question posed by the student.
In the above step 402, in order to ensure the continuity of the online teaching, the online teaching may be divided into multiple question periods, so that the number of questions in each question period is counted.
The time length of each question period may be set to be the same time length.
In one implementation manner, in order to set the questioning period of each online teaching course in a targeted manner, the duration of the questioning period of each online teaching course can be determined according to the number of students who have class in each online classroom and the principle that the more students are in class and the longer questioning period is.
Such as: the server stores the corresponding relationship between the number of students who attend the class and the questioning period as follows:
the number of the people in class: the following question period duration for 30 people: for 3 minutes.
The number of the people in class: question cycle duration of 30 or more and 80 or less: for 5 minutes.
The number of the people in class: the question period duration of more than 80 persons: for 8 minutes.
Then, when the number of the online class students is 55, the server may set the length of the questioning period of the online class to 5 minutes according to the stored correspondence between the number of the online class students and the questioning period.
That is, before the step 402, the statistical method for the number of hands held according to the present embodiment further needs to set the question period of the online class, and in order to set the question period of the online class, the following steps (1) to (2) may be performed:
(1) counting the number of the students who ask questions in the on-line class;
(2) and setting the question period of the on-line class in which the students ask questions according to the corresponding relation between the number of the students who have class in the on-line course and the question period.
It can be seen from the above contents that the questioning period of each online course is set according to the principle that the more students are in class and the longer the questioning period is, and the questioning period of the online courses with the more students is set is longer, so that more students can have the opportunity of questioning teachers, and the interactivity between the teachers and the students is further improved.
Specifically, in order to count the number of questions in the current question period, the above step 402 may perform the following steps (1) to (4):
(1) obtaining a questioning student list in a current questioning period, wherein student identifications of students who send questioning requests in the current questioning period are stored in the questioning student list in the current questioning period;
(2) traversing a questioning student list according to the student identification of the student carried in the questioning request;
(3) when the student identification carried in the questioning request is not obtained in the questioning student list in a traversing manner, determining that the student does not question in the current questioning period, and performing incremental operation on the number of questioning persons;
(4) and when the student identification of the student carried in the questioning request is obtained in the questioning student list in a traversing manner, the student identification carried in the questioning request is placed in the questioning student list of the next questioning period of the current questioning period.
In step (1), after determining the question period of the online course, the server will allocate a question student list to each question period of the online course.
And the questioning student list distributed in each questioning period of the online course is cached in the server and is used for storing the student identification of the students capable of questioning in each questioning period.
Therefore, the questioning student list in the current questioning period stores the student identification of the student who issued the questioning request in the current questioning period.
In the step (3), the number of questioning persons is increased by 1 based on the current number of questioning persons, so as to obtain the number of questioning persons after the increasing operation.
It can be seen from the contents described in the above steps (1) to (4) that in each question asking period, each student can only ask questions once, so that the situation that the same student asks the teacher repeatedly for the same question is avoided, more students can have a chance to ask questions to the teacher, more students can interact with the teacher in an online class, and the user experience of the online class is improved.
After distributing the questioning student list in each questioning period, the server needs to calculate a questioning number threshold, and in order to calculate the questioning number threshold, the questioning number threshold can be calculated by the following formula:
the threshold value of the number of questions is the ratio of the number of the students in class to the number of the questions in the online class.
The questioning person number ratio can be set to any value between 0.4 and 0.8.
After the threshold number of questions is calculated, the following step 104 may be continued to instruct the teacher to answer the student's questions online.
And 404, when the number of the questioning persons after the increment operation reaches a questioning number threshold value, sending answer questioning information to a teacher giving lessons to the online course of the student, wherein the answer questioning information is used for indicating the teacher to answer the questioning of the student online.
In the step 404, according to the name of the teacher teaching course associated with the student identifier of the student, a teacher giving lessons to the online course of the student, that is, a teacher who should answer questions of the student, is determined, and the answer question information is sent to the determined teacher client used by the teacher, and is displayed to the teacher for viewing, and waits for the teacher to click.
In one embodiment, the answer question information may be: "ask more students, ask questions asked by students at present.
When the teacher clicks the answer question information, the statistical method for the number of questions asked in this embodiment may further perform the following steps:
and when receiving answer and question response information fed back by the teacher based on the answer and question information, sending the student identification and the question content of the students asking questions in the current question period to the teacher, so that the teacher answers the question content of the students on line.
Here, the answer quiz response information is response information automatically generated by the teacher using the client after the teacher clicks the answer quiz information, and is used to instruct the server to send the student identifications and quiz contents of students asking questions in the current quiz period to be answered to the teacher.
In summary, according to the statistical method for the number of questions asked in this embodiment, after the question requests of the students are obtained, when it is determined that the students in the current question period have not asked questions according to the student identifiers of the students in the question requests, the number of questions asked in the current question period is subjected to increment operation, and when the number of questions asked after the increment operation reaches the threshold value of the number of questions asked, a teacher is instructed to answer the questions asked by the students on line, and after the students send the question requests, the students can interact with the question statistics device to perform the increment operation on the number of questions asked in the current question period, so that the number of questions asked in the current question period is counted; moreover, only when the student who sends the questioning request in the current questioning period has not asked the question, the student can be asked questions in the current questioning period, the situation that the same student repeatedly asks the teacher for multiple questioning with respect to the same question is avoided, the accuracy of counting the number of students to be asked questions is improved, more students can ask questions of the teacher, the interaction between the teacher and the students is increased, and the user experience of online teaching is improved.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
