Problems solved by technology

With the continuous advancement of science and technology, it has gradually become a trend to use computers to arrange and complete exercises. However, in the correction of subjective questions and calculation exercises that need to list the steps to solve the problems, teachers still need to carefully study and judge step by step.
In addition, in the proc

Embodiment Construction

[0030] The technical solutions provided by the present invention will be described in detail below in conjunction with specific examples. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0031] A correction and feedback method for arithmetic exercises is realized based on a homework correction software system. This method must provide a visual input and output interface. The specific implementation includes the following steps:

[0032] (1) if figure 1 As shown, the correcting model is established first, and the teacher pre-enters the standard answers, formal requirements, and problem-solving steps of various problem-solving methods on the input interface, and classifies the problem-solving steps. When the teacher enters the topic, he should pay attention to the requirement of the topic must be accurate, for example, for a certain topic, whether ...

Abstract

The invention discloses an operation exercise correction and feedback method implemented by software. Operation steps can be compared step by step, various data can be counted, and a large mount time is saved for a teacher. The operation exercise correction and feedback method includes the steps: firstly building a correction model, pre-recording standard answers, form requirements and problem solving steps of various problem solving methods of a problem, classifying the problem solving steps and inputting grading detailed rules; inputting problem solving steps and answers by a student and verifying a form; converting the inputted answers into ASCII (American standard code for information interchange) codes and preprocessing the codes; comparing the problem solving steps submitted by the student with the standard problem solving steps in sequence, and grading according to the grading detailed rules; and feeding back a correction result to a visual interface and counting the data.

Description

technical field [0001] The invention belongs to the technical field of computer software, and in particular relates to a correction and feedback method for arithmetic exercises. Background technique [0002] For a long time, the teaching process has been filled with a lot of exercises and various types of tests. After the students have completed the exercises, the teacher must spend a lot of energy on the correction work. At present, people are gradually looking for automated methods to replace heavy manual operations. Some corrections, such as the correction of objective questions (that is, multiple-choice questions), have been realized by machines that automatically read the answer sheets. With the continuous advancement of science and technology, it has gradually become a trend to use computers to arrange and complete exercises. However, in the correction of subjective questions and calculation exercises that need to list the steps to solve the problems, teachers stil...
