Homework correction device

Abstract

The invention discloses a homework correction device. The homework correction device comprises an input module, a recognition module, a knowledge base module, an inference rule base module, an automatic revising module, an automatic checking module, an automatic correction module and a recording module, wherein the input module is used for acquiring text information or picture information of homework to be corrected; the recognition module is used for recognizing the text information or picture information as knowledge points; the knowledge base module is used for expressing the knowledge points through predicate logic; the inference rule base module is used for establishing an inference rule according to the generally acknowledged truth, the theorem, the definition and the formula; the automatic revising module is used for discovering errors occurring in the solving process and obtaining the follow-up correct solving process through the backtracking technology; the automatic checkingmodule is used for checking the completeness of the solving process of students; the automatic correction module is used for calling the recognition module, the knowledge base module, the inference rule base module, the automatic revising module and the automatic checking module for automatically correcting and revising the homework, and storing the correction result; the recording module is usedfor recording the automatically revised part of the homework or the incomplete part in automatic checking, and the knowledge points and the inference rule relevant to the parts.

Description

technical field [0001] The invention relates to an intelligent teaching system, more specifically, to a homework correction device. Background technique [0002] At present, primary and middle school students are faced with a large amount of homework, especially the homework of elementary mathematics, which brings a considerable workload to the teacher for correcting homework. In addition to dealing with the busy daily work, the teacher also needs to do a lot of homework for the students. corrected assignments. In recent years, with the continuous and in-depth development of artificial intelligence technology, people have continuously proposed to use intelligent technology to solve the traditional way of homework correction, so that teachers can be liberated from the tedious work of homework correction. [0003] In the related technology, the automatic correcting homework device uses simple scanning equipment to scan the content of the student's homework, stores it in the s...

Problems solved by technology

The disadvantages of this existing technology are: first, it is necessary to enter the standard answers first, and then use the students' answers to match the standard answers to give the correction results, so it is difficult to automatically reason and judge according to the students' problem-solving process, especially for some It is impossible to feed back the diversity of students' answers to the questions of solution; secondly, it is difficult to automatically feed back the places where students make mistakes, and it is also impossible to further analyze the reasons for students' mistakes
