Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cloud computing, and in particular to a test question automatic correction trace leaving device. BACKGROUND

[0002] School education, as the main way of scientific and cultural knowledge learning, in order to help students master knowledge, homework and test paper exercises are essential. Now whether it is primary school, junior high school, high school or even university, students need to do homework and test paper exercises, at the same time, school teachers generally face the problem of correcting dozens or even hundreds of students' homework and test papers, and the workload and work pressure of school teachers are large.

[0003] Therefore, in order to save the workload of teachers' homework and test paper correction, automatic correction emerges as the times require. The simplest automatic correction method we know is the correction method of the selected question part in the high school entrance examination and the middle school entrance examination, which realizes the answer by filling and pasting the selected question on a special answer sheet, and realizes the automatic recognition and correction by loading the answered answer sheet into the card reader. The automatic correction through the answer sheet needs to cooperate with the special answer sheet, which increases the learning cost of students, in addition, the filling and pasting of the answer sheet has certain requirements for the filling and pasting operation of students, which increases the learning and operation cost of students, therefore, the answer sheet is generally suitable for some important unified examination, and is not suitable for the automatic correction of students' homework and test paper.

[0004] With the development of technology, there appears a method of obtaining test question pictures by scanning students' homework or test paper, recognizing test questions in test question pictures by using picture recognition technology, and realizing automatic correction by means of big data analysis and matching. This automatic correction method belongs to electronic correction, and cannot restore the correction marks to the students' homework or test paper, so that the students cannot directly obtain the correction result on the homework or test paper, and need to refer to the electronic correction result, which causes inconvenience in students' learning. In order to solve this problem, some products use the secondary printing method to print the correction marks on the original test paper of students. However, the secondary printing method has many problems in actual use, including slow printing speed, high cost of equipment and consumables, and easy damage to students' homework.
