First, the definition of manual marking and network marking
1, manually marked
As the name implies, manual marking is the teacher's manual marking. The biggest advantage of this marking method is that students can see their own wrong questions, so that they can practice their wrong questions more pertinently. But there are still many shortcomings, such as taking too long, affecting the quality of marking.
2. Online marking
The full name of online marking is online marking system, which refers to a modern computer system that relies on computer network technology and electronic scanning technology to realize automatic marking of objective questions and online marking of subjective questions.
Second, online marking has functions that manual marking does not have.
1 to ensure the quality of marking.
(1) Automatically screen candidates' information to ensure the objectivity and fairness of the marking process.
(2) For any subject and topic, the error control mechanism of double evaluation and multi-evaluation in any proportion and the consistency check of marking ensure the accuracy of marking results.
(3) The real-time progress and quality monitoring function ensures that the marking progress and quality can be grasped in time.
(4) Automatic grading, scoring and statistical analysis, which avoids the possible errors caused by manual operation and ensures the quality of statistical analysis.
2. Reduce the burden on teachers.
(1) Manual operations (binding, moving, browsing, and exchange) on the paper answer sheet are omitted.
(2) In the pipeline marking state, the mutual waiting time is saved.
(3) Eliminate a lot of data processing and statistical analysis (all done automatically by the system). The practical application results show that the efficiency of online marking is more than five times that of manual marking.
3. Improve the teaching level.
(1) Detailed analysis of individuals, classes, grades (schools), subjects, topics, minor problems (knowledge points) and comprehensive analysis of multiple exams.
(2) Statistical analysis of test results (actual scores) and comprehensive judgment of the test itself (difficulty, reliability, discrimination, validity, etc.). The above functions can provide scientific basis for teaching diagnosis and targeted teaching in education bureau or school, which is of great help to improve teaching quality and level.
4. Achievement data sharing is realized.
Automatic marking of objective questions, online marking of subjective questions and statistical analysis of achievement data are all carried out on the computer network. In particular, statistical analysis data can be published directly on the server, which can not only avoid the trouble of manual marking, summary and reporting, but also be directly used for teaching evaluation and quality analysis, so as to maximize the resource sharing of achievement data and meet the needs of leaders, teachers, students and parents.
