Embodiment Construction

[0034] The invention provides a method and a system for visualizing the detection index of the marking quality of a marking examiner. In order to make the object, technical solution and effect of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0035] see figure 1 , figure 1 It is a structural block diagram of the visual system of the detection index of marking quality of the marking staff of the present invention. As shown in the figure, the system includes: an acquisition unit 100 , a statistical unit 200 , a curve fitting unit 300 , an evaluation unit 400 and a drawing unit 500 .

[0036] Specifically, the collection unit 100 is used to collect the assessment information of the examiners on the test p...

Abstract

The invention discloses an imaging method and system of detection indices of marking quality of markers. The method comprises the following steps of: by collecting the assessment information of test papers of the markers, making an S-P (Student-Problem) table according to the assessment information; drawing a marker scoring S-curve according to the data of the S-P table; calculating a marker CS (caution index for students) and a self-consistency coefficient P1 of the markers according to the marker scoring S-curve; and finally, drawing an image of the detection indices of the marking quality of the markers by utilizing the marker CS and the self-consistency coefficient P1 of the markers. Accordingly, the marking quality of the markers is objectively reflected by the data, and meanwhile, the marking level of the markers can be visually seen by users by an image method.

Description

technical field [0001] The invention relates to the technical field of examination paper evaluation, in particular to an image method and system for detecting indicators of examination paper marking quality by examiners. Background technique [0002] Most of the current grading systems use computers as tools to convert the scanned test papers into images, which are then graded by the graders on the Internet. The current multi-assessment mechanism is implemented in the college entrance examination, high school entrance examination and other examinations: it means that each question of the same test paper has a plurality of (usually more than two, up to four) examiners give scores, and then, Scores meeting the minimum error requirement will be accepted in accordance with the requirements for grading error. This approach avoids the arbitrariness brought about by one person's grading, thus achieving the fairness of grading. [0003] However, for the examiners, they have incons...
