It is sent to teacher's terminal to cloud platform, and by cloud platform；
Each section's class schedule is provided in the attendance detection module, when attendance detection module detects on the seat without student
Or substitute when checking card, compared according to current time and each section's class schedule, judge course that the student lacks with it is scarce
Class number, and then count the rate of attendance of each student's every month, obtain each student rate of attendance set Dj (dj1, dj2 ...,
Dje), Dj is expressed as each section's rate of attendance set of j-th of student, and dje is expressed as e-th of section's purpose rate of attendance of j-th of student；
The task detection module is used to detect the students' work performance of student, and by the students' work performance of detection and always
The need amount of fulfiling assignment compared, obtain the performance of students' work, the performance of students' work, which is sent to cloud, puts down
Platform, while the answer that operation is completed is sent to answer contrast module；
The answer contrast module compares the model answer of answer and setting that operation is completed, to calculate student
It practises and grasps coefficient, and by the learning and mastering coefficient feedback of student to cloud platform, while extracting and the inconsistent student of model answer
The serial number of wrong topic corresponding to completed operation answer, and the topic serial number of mistake is sent to wrong topic uploading module；
The wrong topic uploading module is used to the wrong topic serial number received being uploaded to cloud platform, and is sent to teacher by cloud platform
Terminal；
Described oriented module is connect with mistake topic uploading module, for extracting the corresponding knowledge point of wrong topic serial number.
6. a kind of smart classroom tutoring system based on cloud platform according to claim 5, it is characterised in that：The answer
Contrast module compares the model answer of answer and setting that operation is completed, respectively obtains certain student's multiple-choice question answer set
A ' i (a ' i1, a ' i2 ..., a ' in), gap-filling questions answer set B ' i (b ' i1, b ' i2 ..., b ' im) are closed, answer answer set is solved
Close C ' i (c ' i1, c ' i2 ..., c ' ik), wherein A ' i, B ' i, C ' i are expressed as the selection of the student of class serial number i
Inscribe answer set, gap-filling questions answer set conciliates answer answer set, if student be completed multiple-choice question/gap-filling questions of operation/
It is consistent with the model answer of setting to solve answer answer, then shows that a ' in are equal to 1/b ' im and are equal to 1/c ' ik equal to 1, if, if
The model answer for the multiple-choice question/gap-filling questions/solution answer answer and setting that operation is completed in student is not met, then shows that a ' in are equal to
0/b ' im are equal to 0/c ' ik and are equal to 0, to calculate the learning and mastering coefficient of each student, and the learning and mastering coefficient of each student
