The third error cause marking unit 32 is configured to obtain third error cause data marked by the teacher; after checking the first error factor data and the second error factor data, the teacher can obtain the true error factors of the students according to the experience of the teacher, and mark the third error factor data by using the third error factor marking unit 32, and the lesson preparation data retrieving unit 33 retrieves the learning data according to the third error factor data, further to be explained, the learning data retrieved according to the third error factor data is the preset data.
Teacher auxiliary system of preparing lessons is when in-service use, and the student is through doing problem module 1 for the first time will solve the problem thinking and first wrong factor data output, will solve the problem thinking and second wrong factor data output again through wrong problem this module 2, makes the teacher can utilize the mistake to look over unit 35 and fully know student's study condition because of looking over unit 31 and third solution thinking to the pertinence prepares lessons.
In addition, the teacher sets the standard solution thought by using the standard solution thought setting unit 34, so that the students can check the standard solution thought in the wrong-answer book module 2, and the problem solving thought can be prevented from being checked when no student is right for the test problem.
Finally, the teacher can also check the plurality of solution ideas after sequencing by using the third solution idea checking unit 35, so that the teacher can conveniently make a standard solution idea.
In this embodiment, the first error factor data includes test question marks and first error factor content; the second error factor data comprises test question marks, second error factor contents and error making times;
the first error factor data is:
q (examination mark) Because the question is wrong because of too many words (the first mistake is due to the content)
The second error factor data is as follows:
Figure BDA0002234074330000071
one or more primary preset error cause labels are preset in the first error cause marking unit 12, one or more secondary preset error cause labels are stored under each primary preset error cause label, and one or more tertiary preset error cause labels are stored under each secondary preset error cause label; if the first error cause marking unit 12 is operated, the student selects at least one primary preset error cause label, a secondary preset error cause label or a tertiary preset error cause label as first error cause content, or the student self-defines at least one self-defined error cause label as first error cause content;
the second error cause marking unit 22 is preset with the same number and kinds of preset error cause labels as those in the first error cause marking unit 12; if the second error cause marking unit 22 is operated, the student selects at least one primary preset error cause label, a secondary preset error cause label or a tertiary preset error cause label as the second error cause content, or the student self-defines at least one self-defined error cause label as the second error cause content.
In this embodiment, the third error factor data includes a test question mark and a third error factor content, when the lesson preparation data retrieving unit 33 retrieves the learning data according to the third error factor data, the corresponding knowledge slice library is found according to the test question mark in the third error factor data, each preset error factor label preset in the knowledge slice library is compared according to the third error factor content, the preset error factor label with the highest similarity to the third error factor content is found, and the learning data corresponding to the preset error factor label is retrieved. The learning data includes video data, voice data and/or text data.
The third error factor data is as follows:
q (examination mark) Misreading because of not paying attention (third error due to content)
In this embodiment, when comparing each preset error cause label preset inside the knowledge slice library according to the third error cause content, the third error cause content is compared with each three-level preset error cause label, then compared with each two-level preset error cause label, and finally compared with each one-level preset error cause label; if the similarity between the preset error factor label and the third error factor content is completely the same in the comparison process, the comparison is stopped, and the learning material corresponding to the preset error factor label is called out.
Here, a first-level preset error factor label is taken as shown in the following table:
it should be noted that, when the third error cause content is compared with the preset error cause labels, the Levenshtein Distance edit algorithm is used for calculation, where it is assumed that the similarity is 100% when the operation step is defined as 0 step, the similarity is 0% when the operation step is defined as 10 steps, the number of operation steps between the operation steps 0 step and 10 step corresponds to the similarity of 100% to 0%, and if the similarity between the third error cause content and all the preset error cause labels is 0%, the lesson-preparation-data retrieving unit 33 outputs the corresponding non-retrieved learning data.
In this embodiment, the tag collection module 4 is configured to collect each user-defined error cause tag. .
It should be noted that the significance of setting the tag collection module 4 is to find a solution corresponding to the error cause content expressed by the collected custom error cause tag, then convert the custom tag into a preset error cause tag, and store the solution as the learning material corresponding to the preset error cause tag. The self-defined wrong cause label is continuously converted into the preset wrong cause label, the quantity of the preset wrong cause labels in the lesson preparation system can be continuously enriched, and therefore the lesson preparation system has better functions.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and all simple modifications, changes and equivalent structural changes made to the above embodiment according to the technical spirit of the present invention still fall within the protection scope of the technical solution of the present invention.
