Description

Whole-course digital teaching method, system and device

Technical Field

The invention relates to the technical field of teaching facilities, in particular to a whole-course digital teaching method, a system and a device.

Background

In the digital era, high-quality teaching resources become one of the core competitiveness of schools, and school teaching must gradually transition from papery textbooks, workbooks, test papers and the like to paperless and digitalized teaching, so how to store big data used for the teaching? There are two methods to protect these big data: firstly, adopting a universal document format; and secondly, adopting a structured document format. The first method is the docx format of microsoft corporation in the united states, which has the advantages that everyone basically uses microsoft Office software, the document editing function is very powerful, taking the teaching flow of student homework as an example: the teacher usually edits a student homework by using Microsoft Office software and then arranges the homework for the students; after receiving the Office file arranged by the teacher, the students use Office software to edit the homework on line, and after writing, submit the homework to the teacher for correction; the teacher can send the completed homework and the correct answer of the homework to the students for checking; the problems of the method are that: 1) the system can not automatically modify the selection questions, fill in the blank questions and the like; 2) the teacher needs to edit at least 2 document files, one is a job without answer display, and the other is a correct answer of the job, the teacher needs to operate carefully, and the system can automatically push the correct answer to the students to check the 2 files; 3) after the student submits the homework, the student can not modify the homework according to the teaching flow, and the editing function of the docx file needs to be limited according to the teaching flow. The second method is to create a document suitable for teaching process by database management, including exercises or jobs, taking the creation of exercises as an example, the teacher selects the type of exercise, the selectable type includes selection, blank filling or subjective, and then inputs the exercise surface through the text box, if it is selection or blank filling, then the answer is input at the position where the input answer is displayed. The method has the advantages that: the system can automatically distinguish the exercise question surface from the exercise question answers, automatically revise the choice questions, fill in blank questions and the like, and the existing problems are as follows: 1) because the document data and the data in the teaching database are not mutually independent, it is difficult to develop editing software with powerful functions similar to Microsoft Office, for example, for subjective questions, not only a powerful editing function with luxuriant pictures and texts needs to be provided, but also a function of handwriting input needs to be provided, the method generally inputs the subjective questions in such a way that students write the subjective questions on paper, then take pictures through a mobile phone to store the pictures, and finally insert the pictures into a system, if the sizes and the positions of the pictures are not proper, the pictures also need to be adjusted, and the user experience is not good; 2) structured documents do not facilitate defining complex problem types, for example, a subjective problem also contains a plurality of blanks to be filled; for another example, it is inconvenient to adjust the positions of the selection questions and the blank filling questions according to the actual test paper layout, and adjust the font sizes of the blank filling questions; 3) the prior digital test paper usually has one page for automatic correction of the problem, and the surface of the paper is not as compact and beautiful as the surface of the paper.

The teacher and the student in the classroom actively interact to improve classroom efficiency, especially in recent years, the tablet personal computer is introduced into the classroom, the teacher and the student do the exercise in the classroom through the tablet personal computer, and the classroom exercise has better interactive effect. The problem that this method exists is, the teacher can't see each student's the step of solving the problem, only waits to finish after the exercise in the same place, the teacher just can look over each student's the answer condition, this is to say, if the answer time needs 10 minutes, then teachers and students do not have the interaction in this 10 minutes, this is unfavorable for the teacher give some hints for the student when being fit for, inspires the student thinking, is unfavorable for mobilizing student's enthusiasm of study for classroom teaching effect is not good.
