Intelligent operation method based on two-dimensional code

Abstract

The invention discloses an intelligent operation method based on a two-dimensional code. after answering, the test paper is photographed through the electronic product and analyzed to generate a testpaper two-dimensional code; the two-dimensional code comprises a student ID and a test paper ID; answer parts of test paper objective selection questions are scanned; a machine learning technology isused for identifying a student handwriting choice question solving process; answers are input in the database, the answer is compared with an answer in the database; score is determined, the result isdirectly displayed to the terminal of the user through handwriting neatening; and in an answering area of the question-solving process, on one hand, a machine learning technology is used for automatically identifying the handwriting neatening degree and obtaining and storing handwriting neatening scores, and on the other hand, teachers are used for reviewing whether questions exist in the question-solving process or not, reviews of the teachers are obtained and stored, and results are displayed to a terminal of the user. And finally, the system reviews the correct questions according to the wrong questions of the students in combination with an Ebbinghaus curve, and the test paper for reviewing the questions still adopts the process, so that the workload of teachers is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of systems used in teaching, in particular to a method for intelligent operations based on two-dimensional codes. Background technique [0002] In some existing teaching systems, it is hoped that the teacher will be bypassed, and students will complete their studies independently by relying on the questions and analysis. However, in reality, artificial intelligence may solve the problem of teaching by example in education, but it cannot solve the problem of teaching by example. For details, please refer to the patent of CN201510067999.6. This patent discloses that QR codes are used in questions. Each topic has its own QR code. You can get the corresponding answer and analysis of each topic by scanning the QR code with your mobile phone. In addition, The patent CN201710351582.1 discloses a test paper based on QR code scanning. After scanning the QR code, the analysis and explanation of the test paper can be o...

AI Technical Summary

Problems solved by technology

However, the division of the difficulty level of the test questions and the self-selection of the questions based on the knowledge mastered by the students cannot be realized through the above-mentioned technology. The traditional way of leaving homework, all the students' homework is unified. Due to the large number of classes, correcting repeated homework is a waste of the teacher's effective explanation time. , and lead to repeat the content that is already proficient, and the unskilled content cannot be practiced as it should be, and the whole class will copy each other after finishing it, resulting in low quality of homework completion and incomplete knowledge points, making it difficult to get good grades

In addition, young teachers lack experience in improving student performance and lack the energy to formulate reasonable learning plans for all students, which brings great difficulties to educational automation

[0003] In addition, the 2B pencil scribbling answer sheet technology is currently an excellent automatic marking technology for objective test questions, but if you do exercises in the training class, you need to scribble the answer sheet every time you do a question, which is a waste of study time

Moreover, students often only have one pen, and the pencil is inconvenient to carry because the pen tip is easy to break, which makes it impossible to perform card painting operations
