Technical Field

The invention relates to the technical field of network teaching, in particular to a method for managing network teaching based on the Internet of things.

Background

The network teaching is a teaching mode which realizes teaching targets by applying multimedia and network technology under the guidance of certain teaching theory and thought, multi-side and multi-directional interaction of teachers, students, media and the like and collection, transmission, processing and sharing of teaching information of various media;

the network teaching is mainly divided into a teaching type and a demonstration type, wherein: the teaching mode is characterized in that a teacher is used as a center to give lessons systematically. The teaching mode is a new development of the traditional class teaching in the network teaching. The lecture-type teaching mode is a teaching mode mainly based on lectures performed using a network as a communication tool for teachers and students. The teaching mode of the teaching network realized by the Internet can be divided into a synchronous mode and an asynchronous mode. The synchronous teaching mode is the same as the traditional teaching mode except that the teacher and the students are not in the same place for class, the students can listen to the teacher for teaching at the same time, and the teacher and the students have some simple communication. Asynchronous teaching can be simply realized by using the Internet Web service and the e-mail service, the mode is that teachers compile teaching materials such as teaching requirements, teaching contents, teaching evaluation and the like into HTML files to be stored on a Web server, and students can achieve the purpose of learning by browsing the pages. The mode is characterized in that the teaching activities can be carried out 24 hours all day long, each student can determine the learning time, content and progress according to the actual condition of the student, and can download the learning content on the internet or ask for teaching to teachers at any time. The main defects are lack of real-time interactivity and high requirements on learning consciousness and initiative of students.

The demonstration type network teaching mode is that a teacher demonstrates various teaching information to students by using a network according to the teaching requirement, wherein the teaching information can be CAI courseware loaded by the teacher or teaching information from a campus network or the Internet.

The teaching mode or the demonstration network teaching mode basically receives information only by students, and lacks the interaction between the students and teachers in real classroom teaching and the interaction between the students and classroom environment, so that the students cannot obtain real learning experience, which is a main factor of low learning efficiency of network teaching.

for the hand swinging type action, the action speed is the time required by the teacher user to swing the hands once, and the action time is the total time of the teacher to swing the hands;

as a further scheme, for the clapping type action, since the teacher device is a mechanical device, and its mechanical joint and structure are difficult to simulate a real clapping, it is necessary to perform simulation in cooperation with sound generation, and based on collecting the clapping audio of the teacher user or pre-storing the clapping audio for playing, the sound generation intensity of the playing can be calculated by the following formula:

wherein Z_iRepresents the sound emission intensity k of the teacher device simulating the clapping action of the teacher user for the s-th time_aTo representReference sound intensity, X_sIndicates the speed of the clapping action of the instructor user at the s-th time,mean, σ, of samples representing the clapping action of teacher user_xA sample standard deviation representing a sample of the teacher user's clapping action;

wherein i is (1, 2, 3.. N), and N is a positive integer.

Wherein Zs, k_aThe unit of (a) is dB, e represents a natural constant, and the rest parameters can be subjected to de-unitization;

based on the formula, the teacher equipment can be controlled to synchronously sound when simulating the clapping action of the teacher user, more real simulation can be provided by matching with the sound intensity of the clapping action of the teacher user, and a teacher feedback scene similar to a real classroom can be obtained.

Step S94, based on the action parameters of the teacher user, the student users required by the teacher user to respond can be identified;

specifically, voice recognition based on the first sound parameter can point to a student user who responds to a request of the teacher user through the recognized student name word;

or the student user of the student terminal 200 contacted by the student device 300 based on the acquisition of the arm motion-driven arm of the teacher device by the teacher user as the student user who responds as requested by the teacher user;

more specifically, as an example, the teacher terminal 100 includes an infrared transmitting device provided on an arm of the teacher apparatus, and the student apparatus 300 includes an infrared receiving device for cooperating with the infrared transmitting device provided on the arm of the teacher apparatus. Based on the cooperation of the infrared transmitting device and the infrared receiving device, the student device 300 is contacted based on the pointing direction of the arm of the teacher device, and the student user is further guided.

Step S95, collecting the action parameters of the student users required by the teacher user to respond based on the student end 200, where the action parameters of the student users include:

a second sound parameter generated by the voice of the collected student user;

a second arm motion parameter generated by collecting arm motions of the student user;

the leg action parameters are used for judging the standing posture of the student user based on the leg action parameters, and the standing posture of the student user at least comprises a sitting posture or a standing posture;

the head action parameters are used for judging the head actions of the student users based on the head action parameters, and the head actions at least comprise head shaking and head pointing;

step S96, driving synchronous action of the student device 300 based on the action parameters of the student user;

driving the arm of the student device 300 to make the same type of arm motion as the student user based on the second arm motion parameter;

driving the arms of the student device 300 to make the same type of leg movements as the student user based on the leg movement parameters;

driving the arms of the student device 300 to make the same type of head movement as the student user based on the head movement parameters;

driving the arm of the student device 300 to make the same voice as the student user based on the second sound parameter;

for example, for the second sound parameter, at least audio data is included, wherein the audio data is the collected human voice of the student;

attaching an intensity parameter to the second sound parameter when the arm of the student device 300 is driven to make the same human voice as the student user based on the second sound parameter, and controlling the intensity of the sound emitted by the student device 300 based on the intensity parameter;

driving the arm of the student device 300 to make the same type of arm motion as the student user based on second arm motion parameters, wherein the second arm motion parameters at least comprise the type of arm motion, the speed of the motion and the time of the motion;

the types of actions include:

lifting, clapping, swinging, etc.;

for the hand-lifting type action, the action speed is the time for completing the arm lifting action of the student user once, and the action time is the total time for lifting the arm of the student user;

for clapping type actions, the speed of the action is the time required by the clapping of the student user once, and the time of the action is the total time of the clapping of the student;

for the hand swinging type action, the action speed is the time required by the hand swinging of the student user once, and the action time is the total time of the hand swinging of the student;
