Online review system for subjective questions

Abstract

The invention discloses an online review system for subjective questions, comprising an image scanning subsystem, a server group, a review subsystem, a synthesis subsystem, and a printing subsystem. The image scanning subsystem uses a scanner to scan the test paper of students into image files. The server group includes an application server, a file server and a database server, wherein the file server is used for storing the scanned image information, and the database server is used for storing data information generated in the review process. The review subsystem calls the scanned images stored in the file server, a paper marker reviews the scanned images, and the paper marker can make marks in corresponding positions of the images to generate mark information. The synthesis subsystem synthesizes the scanned images and the mark information into complete reviewed test paper, and stores blank paper containing the mark information only. The printing subsystem uses a printer to print the mark information in the blank paper on the test paper of students. With the system, the problem that marks cannot be made through the existing online review system, which fails to facilitate review by paper markers and error analysis by students is solved.

Description

technical field [0001] The invention relates to information processing technology on the Internet, in particular to an online evaluation system for subjective questions. Background technique [0002] The use of computer review refers to a new review method based on computer network technology and image processing technology, with the ultimate goal of realizing the principle of fairness and impartiality in test marking. It combines the rich experience of traditional manual review and modern high-tech for many years, and adopts the method of separating the test paper and answer sheet. The objective questions are automatically graded by the computer, and the subjective questions are evaluated by different reviewers on the computer through the network. Scoring is carried out separately, and finally, the computer device automatically checks the scores and checks the results. The use of computer online evaluation can effectively prevent the mutual influence among the marking teac...

Problems solved by technology

However, the existing computer evaluation system has the following problems: (1) The graders cannot mark the subjective questions when they judge the subjective questions, and can only give an overall impression score, which has strong subjective factors; (2) The keyboard operation does not meet the requirements of the graders. (3) Students only know their grades when they get the test papers, but they don’t know where they lost their marks, which makes it inconvenient for students to analyze and summarize their mistakes; (4) Staring at the existing computer for a long time The screen is easy to cause eye fatigue and radiation spots to the examiners
