Description
Technical Field
The invention belongs to the technical field of teaching quality analysis, and particularly relates to a classroom teaching quality analysis system based on perception analysis.
Background
Teaching quality assessment is an important part of the comprehensive ability test of schools to teachers, and currently, most assessment means of teaching quality are manually scoring and counting, the work content is complex, mistakes are easy to make, and the constitution is unreasonable to evaluate. With the development of networks, education and learning are increasingly networked, various education and learning websites are produced, however, the existing education and learning websites mostly emphasize the autonomy of students excessively, neglect to evaluate and monitor the learning activities and learning effects of the students, and educators cannot adjust according to the teaching contents of the learning conditions of the students, so that the needs of the students are hardly met, the learning effects are reduced, and the educators timely evaluate the education results and timely adjust the teaching contents according to the evaluation results, which is an important means for improving the teaching quality.
However, most of the existing education assessment methods adopt a traditional method, that is, an educator analyzes the teaching homework according to the situation that the student completes the teaching homework, so as to know the learning situation of the student, and then adjusts the teaching content according to the learning situation of the student, and the traditional education assessment method has the following defects that the simple assessment method usually causes that mass data is simply processed, information obtained by the educator is only a small amount, a large amount of effective information is wasted in the processing process, and the educator cannot accurately obtain the assessment result, so that the adjustment of the teaching content cannot completely adapt to the requirements of the student, the teaching cannot be improved in real time, and a scientific basis cannot be provided for improving the teaching level.
Disclosure of Invention
The invention aims to provide a classroom teaching quality analysis system based on perception analysis, which is intelligent and convenient, does not need manual operation of teachers, effectively improves teaching quality and reduces teaching burden of the teachers.
A classroom teaching quality analysis system based on perception analysis comprises a data server, a perception analysis module, a positioning module and a display module;
the data server comprises a database, an evaluation unit, a position analysis unit and a matching unit;
the evaluation unit compares the obtained lip language identification information and extracts classroom problem information in a database, and the evaluation unit scores the lip language identification information according to the similarity after matching the information similarity;
after the position analysis unit acquires a plurality of broadcast messages associated with the same physical address, the position analysis unit calls the position of a Bluetooth acquisition device for sending the broadcast messages, and calculates the position of the mobile equipment according to the position of the device and the message strength;
the perception analysis module comprises an image acquisition unit and an identification unit, the image acquisition unit acquires a lip language image of a user and sends the lip language image to the identification unit, and the identification unit identifies the acquired lip language image and sends the lip language image to the data server;
further, the database is used for storing classroom problems and student information.
Further, the classroom questions are uploaded to a system by a teacher and used for evaluating teaching quality.
Further, the student information includes student numbers, each student number associated with a mobile device physical address.
Furthermore, the positioning module comprises a plurality of Bluetooth acquisition devices arranged in the classroom, the Bluetooth acquisition devices acquire broadcast messages sent by the mobile equipment and identify the physical addresses of the mobile equipment, and the Bluetooth acquisition devices associate the intensity values of the broadcast messages with the physical addresses and then send the intensity values to the data server.
Further, the display module is used for displaying classroom problems.
Further, the matching unit obtains the position of the mobile device and the position of the seat for matching, and stores the successfully matched seat number and student number after associating.
The purpose of the invention can be realized by the following technical scheme:
the invention has the beneficial effects that:
the invention discloses a teaching quality analysis system, which collects the positions of seats of students through Bluetooth signals, records the answering conditions of the students through lip language identification when the students answer questions, and matches the answering conditions with standard answers, thereby recording the classroom teaching quality.
