Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In order to make the objects, technical solutions and advantages of the present invention clearer, the following detailed description of specific embodiments of the present invention is provided with reference to the accompanying drawings, and the embodiments are not limited to the embodiments of the present invention.
Fig. 1 is a flowchart of a method for interacting an online classroom provided by an embodiment of the present invention, fig. 2 is a schematic structural diagram of signaling transmission for the interactive online classroom provided by the embodiment of the present invention, and fig. 3 is a schematic structural diagram of the interactive online classroom provided by the embodiment of the present invention, where the method includes the following steps:
The client comprises a native application program and a web classroom application; rich interaction online classes that combine web class applications and native technologies use courseware made with web technologies to attend classes. The classroom includes two roles, i.e. teacher and student, and teacher and student all use the client program, and first client is the client that first user teacher used, and the operating instruction can be to turn over one page.
The long connection communication realizes the classroom experience with delay far lower than that of video stream, and data is transmitted only when an event occurs, thereby greatly reducing the use of network bandwidth. The long-connection low-delay network communication is used, and the real-time information synchronization at the teachers and the students can realize the two-way interactive classroom experience.
And 102, after receiving the operation instruction, the second client calls the web classroom application and triggers corresponding actions on the web classroom application.
Through the bridging API layer, the native application and the web classroom application call and transfer information with each other.
The client supports the hybrid application of the web classroom application technology through the embedded browser. The Web technology part uses standard Web technologies such as HTML, CSS, JavaScript and the like to realize a complete courseware playing system and an interactive classroom. By embedding a browser, rich courseware and other teaching content are presented in a classroom using web technology.
Optionally, the second client sends the call request information and the operation instruction to the web classroom application, and the web classroom application responds to the operation instruction and triggers a corresponding action according to the call request information and the operation instruction.
When a teacher goes to class, an operation instruction input to a courseware by a first client is transmitted to a student end of a second client through a long connection channel supported by a primary client, the student end processes the operation instruction after receiving the operation instruction signaling and triggers corresponding actions on web contents, and the operation from the student end to the teacher end is similar.
For example, when the teacher turns the courseware to the next page, the courseware on the student side can also turn the pages synchronously at once. The teacher triggers an animation in a courseware, and the student can immediately see the animation played locally.
The Web courseware system opens up data barriers for courseware software providers and teaching resource providers due to incompatibility of data and protocols. In the process of Web courseware making and Web classroom class, teachers can conveniently and directly quote rich teaching resources. For example, a teacher may insert a graphic representation of the mathematical geometry theorem or a photograph of the physical experimental equipment in a courseware. The data subjects in the subject database can be well integrated with the web technology, teachers can select appropriate subjects, explain the subjects in the teaching process, and enable students to answer online, so that a complete courseware playing system and an interactive classroom are realized.
Optionally, counting the calling times of courseware data and teaching resource information; and calculating the average answering time of the questions in the second client side, the correct rate of the submitted answers and wrong question records.
The Web classroom application makes the data and presentation of courseware, teaching resources, question bank questions open, and allows the system to accurately record each interactive event and resource usage. For example, the number of times a certain experimental picture or lecture piece is used, the average answering time and the correct rate of answer submission for a question, the student's answer, the wrong-answer record, etc. The data objectively evaluate the teaching quality, problems in teaching can be found and improved through data analysis, and the most effective teaching mode can be found in a statistical sense, so that the teaching quality is improved. And recording the interaction behaviors in the classroom, and carrying out statistical analysis together with the courseware digital information to obtain a data conclusion helpful for teaching and learning.
Optionally, the native application is used for audio/video codec transmission, local resource access, low-latency data communication, and teaching device connection.
Optionally, the web classroom application encodes the audio and video by using a protocol supported by the native application program to obtain an audio and video packet, and sends the audio and video packet to the native application program; and the native application program acquires the audio and video packet, and the protocol supported by the native application program is adopted to decode the audio and video to obtain the audio and video.
