Its characteristics: 1. Automatic evaluation and analysis. The system will automatically make statistics and judgments according to the set standards, and can automatically generate various reports and analysis reports, which greatly simplifies the workload of users and greatly reduces the error rate of manual operation. Therefore, the test results are generally intelligent data, and human factors cannot be changed. 2. Make full use of the concept and thought of * * evaluation, the theory and technology of education measurement, education statistics and education evaluation, especially the good technology of establishing "regional norm table" and realizing "processing ability" evaluation, and organically combine summative evaluation with formative evaluation. 3. The flexible modular building block design system provides a large number of data analysis indicators that can run independently, and users can freely combine many analysis indicators according to the needs of different teaching and scientific research; The system consists of several independent and interrelated subsystems, and data can be exchanged between the systems through standard program interfaces. 4. Architecture mode based on "cloud" service, using. N E T and cloud computing technology and using W E B access, internal data can be automatically shared and seamlessly connected, and monitoring and evaluation of teaching, scientific research and learning can be realized at the same time. Users can log in anytime and anywhere, which meets the monitoring and evaluation needs of different angles, roles and time periods.
