Application method of regular expression in automatic subjective question correction in computer teaching

Abstract

The invention discloses an application method of a regular expression in automatic subjective question modification in computer teaching, which comprises the following steps: S1, a student inputs and submits subjective answer content of subjective questions through an answer module, and the subjective answer content is submitted to a question bank at the moment; s2, a rule module sets a correction rule of a regular expression, obtains the correction rule of the regular expression, and obtains subjective answer content of students through a screening and extracting module after the subjective answer content submitted by the students is sent to a question bank; and S3, the subjective answer content of the student is corrected according to the binding situation of the subjective test questions and the correction rules of the regular expression, then a correcting result is outputted and the teacher knows the answers of the students. According to the invention, traditional teachers can correct and inquire answers of students one by one and then automatically consult the answers, the pressure of the teachers is reduced in the teaching process, the question correcting efficiency is improved, and the teachers and the students can more visually evaluate wrong questions, so that the learning efficiency and effect of the students are improved.

Description

technical field [0001] The invention belongs to the technical field of information teaching, and in particular relates to an application method for automatically changing subjective questions in computer teaching with regular expressions. Background technique [0002] With the improvement of teaching informatization, there are more and more scenarios of using computers or informatization to answer questions. In traditional course teaching, students answer questions and submit them to the teacher one by one. The teacher checks one by one and gives the corresponding results. , the teacher’s work load is relatively heavy, and he cannot handle more than a certain amount of answer corrections well, especially subjective questions. The students’ answering methods and contents are different, which virtually increases the teacher’s burden. Students' subjective answer content is dynamically analyzed by information technology to reduce the burden on the teacher. For this reason, we p...
