The examination room needs a large number of professional teachers to invigilate and score, but the teachers are seriously insufficient, and it is difficult to allocate them evenly
There may be subjective differences in the evaluation of multiple people by one teacher, which affects the objectivity and fairness of the score;
The experimental operation process cannot be traced, resulting in no basis for scoring review, and it is difficult to eliminate the objections of students and parents
The workload of data collation after the examination is large, and it is difficult to quickly solve the problem of lack of basic data for experimental teaching and research.
The 2024 Henan Provincial Physical, Chemical and Biological Experimental Operation Examination will be held from April 1st to April 30th, so in the examination process, how to make full use of modern technology, gradually make the examination enrollment system more scientific, perfect, fair and just, and avoid the problems existing in the traditional experimental examination. What is the correct way to open a fair and unbiased lab exam?
The physical and chemical biology intelligent evaluation system is a special system for the experimental practical examination of junior and senior high school academic levelOne system with two modes, the system integrates the test terminal, the test system, the touch screen, and the camera, which can quickly build the test environment and take it at any time. It can be applied to physics, chemistry and biology in junior and senior high schools to meet the teaching, training and examination needs of different scenarios.
1. One system, two modes
Through the same set of hardware systems, the two modes of examination and teaching are run separately, integrating teaching, learning, patrol, practice, management, arrangement, evaluation and analysis, forming a closed loop of business ecology of "promoting teaching by examination and teaching by teaching". In the physical and chemical biology laboratory examination, many problems such as difficult examination organization, high manpower consumption, and inconsistent scoring are solved, and through the reuse of equipment, a new experimental teaching model of real-time interconnection and interaction and full-time multi-dimensional learning is created in daily teaching.
2. Hierarchical management and intelligent evaluation
The physical and chemical laboratory evaluation system is preset with a first-class management platform, which can quickly and quickly complete the one-stop evaluation work such as the organization, implementation, scoring, scoring, query, statistics and analysis of experimental evaluation, which can greatly improve the examination efficiency of laboratories, teachers and students.
3. Remote inspection and visual invigilation
The visual invigilation of the examination room and the remote inspection of the municipal platform provide a full view of the examination room, assessment and candidates, grasp the rhythm of the examination and evaluation in real time, realize the whole closed-loop solution, and make the experimental examination easier and fairer.
4. Intelligent scoring, fairness and justice
A large amount of experimental data is collected by the camera for algorithm deep learning, so as to realize the cognition of equipment, the identification of experimental procedures, and the scoring of experimental results. Real-time scoring, high accuracy, fairness and justice.
5. Record the whole process and teach intelligently
The system can also be used for full recording of the classroom process, so that the teacher can concentrate on the lecture, and the system can be reviewed after class, so as to check and fill in the gaps in a targeted manner and improve teaching efficiency.
The physical and chemical biology intelligent evaluation system is problem-oriented, promotes the development of experimental teaching, and provides a comprehensive solution for the physical and chemical biology laboratory operation examination in middle schools. It not only has the international leading technical level, but also can meet the actual needs of physical and chemical biology laboratory teaching in middle schools.
