First, the system for downloading student homework and analyzing homework disclosed in the present invention is illustrated below, and referring to
The system for downloading student homework and analyzing homework disclosed in present invention includes: a server 10, a data providing client 20 and plurality of mobile clients 30. The server 10 further includes: a receiving module 11, a comparing module 12, an analyzing module 13, a generating module 14 and a transmitting module 15.
A teacher first uploads a lesson file to the server 10 through the data providing client 20. The lesson file includes a question area, an answering area and an answer area, where the question area is the question content assigned by a teacher, the answering area is answering process content for the question of a student, and the answer area is the answer content for the question of the student. When the data providing client 20 needs to upload the lesson file to the server 10, the data providing client 20 establishes a connection with the server 10 (the data providing client 20 may establish a connection with the server 10 in a wired transmission manner or a wireless transmission manner, where the wired transmission manner is such as: a wired network, and a transmission line, and the wireless transmission manner is such as: a wireless network, WIFI, and Bluetooth, which are merely exemplified herein, and do not limit the application scope of the present invention). The data providing client 20 may provide the lesson file to the receiving module 11 of the server 10, and the forgoing data providing client 20 may be a desktop computer, a notebook computer, a tablet computer, a smartphone, and so on, which are merely exemplified herein, and do not limit the application scope of the present invention.
After receiving the lesson file provided by the data providing client 20, the receiving module 11 of the server 10 may store the lesson file in the server 10. When the student writes homework, the student obtains the lesson file from the server 10 through the mobile client 30 held by the student to write the homework. The mobile client 30 establishes a connection with the server 10 (the mobile client 30 may establish a connection with the server 10 in a wireless transmission manner, where the wireless transmission manner is such as: a wireless network, WIFI and Bluetooth, which are merely exemplified, and do not limit the application scope of the present invention). The transmitting module 15 of the server 10 transmits the lesson file to the mobile client 30, the mobile client 30 may obtain the lesson file from the server 10, and the forgoing mobile client 30 may be a portable device such as a notebook computer, a tablet computer and a smartphone, which are merely exemplified herein, and do not limit the application scope of the present invention.
After the student obtains the lesson file from the server 10 through the mobile client 30, the student may record the answering process in the answering area of the lesson file, and record the answer in the answer area of the lesson file. After completing the answering, the student establishes a homework file, where the homework file includes the student number of the student, and the homework file may further be provided to the server 10 through the mobile client 30.
After receiving the homework file provided by each mobile client 30, the receiving module 11 of the server 10 may compare answer content of the answer area in the homework file with a corresponding standard answer through the comparing module 12 of the server 10, and when the comparing module 12 of the server 10 finds through comparison a comparison result that the answer content is inconsistent with the standard answer, the analyzing module 13 of the server 10 extracts answering content of an answering area corresponding to the answer content in each homework file and performs similarity analysis on any two pieces of answering content to calculate a plurality of similarity values.
Specifically, it is assumed that answering content of a certain answering area of a first homework file is “2x+2x=4x” and answer content of an answer area corresponding to the answering area is “4x”; it is assumed that answering content of an answering area, corresponding to the first homework file, of a second homework file is “2x+2x=4x” and answer content of an answer area corresponding to the answering area is “4x”; and it is assumed that answering content of an answering area, corresponding to the first homework file, of a third homework file is “1x+3x=4x” and answer content of an answer area corresponding to the answering area is “4x”; a standard answer corresponding to the answer content is “5x”.
The comparing module 12 of the server 10 compares the answer content “4x” of the answer area in the homework file with the standard answer “5x”, and may find through comparison that the answer content “4x” of the answer area is inconsistent with the standard answer “5x”. At this time, the analyzing module 13 of the server 10 extracts the answering content “2x+2x=4x” of the answering area corresponding to the answer content “4x” of the answer area in the first homework file, the analyzing module 13 of the server 10 extracts the answering content “2x+2x=4x” of the answering area corresponding to the answer content “4x” of the answer area in the second homework file, and the analyzing module 13 of the server 10 extracts the answering content “1x+3x=4x” of the answering area corresponding to the answer content “4x” of the answer area in the third homework file.
Next, similarity analysis is performed on the answering content “2x+2x=4x” of the first homework file and the answering content “2x+2x=4x” of the second homework file, it may be found through analysis that the answering content of the first homework file is completely consistent with the answering content of the second homework file, namely, a similarity value of the first homework file and the second homework file is “100”.
Next, similarity analysis is performed on the answering content “2x+2x=4x” of the first homework file and the answering content “1x+3x=4x” of the third homework file, it may be found through analysis that the answering content of the first homework file is not completely consistent with the answering content of the third homework file, namely, a similarity value of the first homework file and the third homework file is “60”.
Next, similarity analysis is performed on the answering content “2x+2x=4x” of the second homework file and the answering content “1x+3x=4x” of the third homework file, it may be found through analysis that the answering content of the second homework file is not completely consistent with the answering content of the third homework file, namely, a similarity value of the second homework file and the third homework file is “60”.
After the analyzing module 13 of the server 10 calculates a plurality of similarity values, the generating module 14 of the server 10 may generate a student number of the homework file with the similarity value exceeding a preset value into a plagiarizing list. The forgoing preset value may be pre-established in the server 10, or a teacher sets the preset value through the data providing client 20, which is merely exemplified herein, and does not limit the application scope of the present invention.
As the forgoing examples, the similarity values calculated by the analyzing module 13 of the server 10 are “100”, “60” and “60” respectively. If the preset value is “70”, it may be obtained that the similarity value “100” exceeds the preset value “70”; and if the student number of the first homework file is “987123123”, the student number of the second homework file is “987456456” and the student number of the third homework file is “987789789”, the generating module 14 of the server 10 may generate the student number “987123123” of the first homework file and the student number “987456456” of the second homework file into a plagiarizing list.
After the generating module 14 of the server 10 generates the plagiarizing list, the plagiarizing list may be transmitted to the data providing client 20 through the transmitting module 15 of the server 10, so the teacher may obtain the student number of the student who plagiarizes homework through the plagiarizing list.
Additionally, after completing the answering, the student establishes a homework file, and the homework file further records answering time of the student in each answering area. The analyzing module 13 of the server 10 analyzes the answering time, and the generating module 14 of the server 10 may generate the analysis of the analyzing module 13 of the server 10 on the answering time into an analysis result. Through the analysis result, whether the student spends too much time in writing homework may be known, and the analysis result is provided to the teacher as a basis for adjusting the homework.
Also, according to the answering time of each answering area recorded in the homework file, the generating module 14 of the server 10 may generate the student number of the homework file with the answering time less than a preset value and the similarity value exceeding a preset value into a plagiarizing list, which also indicates that the student spends too less time in writing homework, so the homework written by the student is very likely plagiarized.
Additionally, according to the answering time of each answering area recorded in the homework file, the generating module 14 of the server 10 may generate the student number of the homework file with the answering time less than different preset values corresponding to each answering area and the answer content consistent with the standard answer into a plagiarizing list. The different preset values corresponding to each answering area indicate the difference of the difficulty of the question area corresponding to the answering area, and the difference of the difficulty of the question area causes the difference of thinking time, calculating time and writing time of the student, so different preset values need to be set according to different difficulty. Even if the answer content is consistent with the standard answer, when the answering time is less than different preset values corresponding to each answering area, it also indicates that the student spends too less time in writing homework, so the homework written by the student may be very likely plagiarized.
Next, the operation manner and the flow of the present invention are illustrated below in an embodiment, and the following embodiment is illustrated with reference to
Referring to
A teacher first uploads a lesson file 41 to a server 10 through a data providing client 20 that establishes a connection with the server 10 (step 110). The lesson file 41 includes a question area 411, an answering area 412 and an answer area 413, where the question area 411 is question content assigned by the teacher, the answering area 412 is answering process content of the student for the question, and the answer area 413 is answer content of the student for the question.
The data providing client 20 uploads the lesson file 41 to the server 10, such as establishes a connection with the server 10 in a wired network manner, and the data providing client 20 may provide the lesson file 41 to the receiving module 11 of the server 10.

After receiving the lesson file provided by the data providing client 20, the receiving module 11 of the server 10 may store the lesson file in the server 10. When the student wants to write homework, the student obtains the lesson file 41 from the server 10 through a mobile client 30 held by the student to write the homework (step 120). The mobile client 30 may for example establish a connection with the server 10 in a WIFI wireless transmission manner, the transmitting module 15 of the server 10 transmits the lesson file 41 to the mobile client 30, and the mobile client 30 may obtain the lesson file from the server 10. The forgoing mobile client 30 may be a portable device such as a notebook computer, a tablet computer and a smartphone, which is merely exemplified herein, and does not limit the application scope of the present invention.
After the student obtains the lesson file 41 from the server 10 through the mobile client 30, the student may record an answering process in the answering area 412 of the lesson file 41, and record the answer in the answer area 413 of the lesson file 41. After completing the answering, the student establishes a homework file 42, where the homework file 42 includes the student number of the student, the homework file may be provided to the server 10 through the mobile client 30 (step 130).
Next, referring to
After the receiving module 11 of the server 10 receives a first homework file 421, a second homework file 422 and a third homework file 423 provided by three mobile clients 30, the comparing module 12 of the server 10 may compare the answering content “2x+2x=4x” of an answering area 413 in the first homework file 421 with the answer content “4x” of the answer area corresponding to the answering area (step 140).
In the embodiment, the comparison result is that the answer content “4x” of the answer area 413 is inconsistent with a standard answer “5x”. At this time, the analyzing module 13 of the server 10 extracts the answering content “2x+2x=4x” of the answering area 412 corresponding to the answer content “4x” of the answer area 413 in the first homework file 421, extracts the answering content “2x+2x=4x” of the answering area 412 corresponding to the answer content “4x” of the answer area 413 in the second homework file 422, and extracts the answering content “1x+3x=4x” of the answering area 412 corresponding to the answer content “4x” of the answer area 413 in the third homework file 423.
Next, similarity analysis is performed on the answering content “2x+2x=4x” of the first homework file 421 and the answering content “2x+2x=4x” of the second homework file 422. It may be found through analysis that the answering content of the first homework file 421 is completely consistent with the answering content of the second homework file 422, namely, a similarity value of the first homework file 421 and the second homework file 422 is “100” (step 150).
Next, similarity analysis is performed on the answering content “2x+2x=4x” of the first homework file 421 and the answering content “1x+3x=4x” of the third homework file 423. It may be found through analysis that the answering content of the first homework file 421 is not completely consistent with the answering content of the third homework file 423, namely, a similarity value of the first homework file 421 and the third homework file 423 is “60” (step 150).
Next, similarity analysis is performed on the answering content “2x+2x=4x” of the second homework file 422 and the answering content “1x+3x=4x” of the third homework file 423. It may be found through analysis that the answering content of the second homework file 422 is not completely consistent with the answering content of the third homework file 423, namely, a similarity value of the second homework file 422 and the third homework file 423 is “60” (step 150).
The similarity values calculated by the analyzing module 13 of the server 10 are “100”, “60” and “60” respectively. If the preset value is “70”, it may be obtained that the similarity value “100” exceeds the preset value “70”. If the student number of the first homework file 421 is “987123123”, the student number of the second homework file 422 is “987456456” and the student number of the third homework file is “987789789”, the generating module 14 of the server 10 may generate the student number “987123123” of the first homework file 421 and the student number “987456456” of the second homework file 422 into a plagiarizing list 43 (step 160).
After the generating module 14 of the server 10 generates the plagiarizing list 43, the plagiarizing list 43 may be transmitted to the data providing client 20 through the transmitting module 15 of the server 10 (step 170). The teacher may obtain the student numbers “987123123” and “987456456” of the students who plagiarize homework through the plagiarizing list 43.
After completing the answering, the student establishes a homework file, and the homework file further records answering time of the student in each answering area. The analyzing module 13 of the server 10 analyzes the answering time, and the generating module 14 of the server 10 may generate the analysis of the analyzing module 13 of the server 10 on the answering time into an analysis result. Through the analysis result, whether the student spends too much time in writing the homework may be known, and the analysis result is provided to the teacher as a basis for adjusting the homework.
Also, according to the answering time of each answering area recorded in the homework file, the generating module 14 of the server 10 may generate the student number of the homework file with the answering time less than a preset value and the similarity value exceeding a preset value into a plagiarizing list, which also indicates that the student spends too less time in writing homework, so the homework written by the student is very likely plagiarized.
Additionally, according to the answering time of each answering area recorded in the homework file, the generating module 14 of the server 10 may generate the student number of the homework file with the answering time less than different preset values corresponding to each answering area and the answer content consistent with the standard answer into a plagiarizing list. The different preset values corresponding to each answering area indicate the difference of the difficulty of a question area corresponding to the answering area, and the difference of the difficulty of the question area causes the difference of thinking time, calculating time and writing time of the student, so different preset values need to be set according to different difficulty. Even if the answer content is consistent with the standard answer, when the answering time is less than the different preset values corresponding to each answering area, it also indicates that the student spends too less time in writing homework, so the homework written by the student is very likely plagiarized.
To sum up, it can be known that, the difference between the present invention and the prior art lies in that in the present invention, a teacher may upload a lesson file to a server through a data providing client for a student to download the lesson file conveniently, and when the student uploads a homework file to the server through a mobile client, the server may find wrong answer content to perform similarity analysis on any two pieces of answering content and calculate a plurality of similarity values, and provide a student number of the homework file with the similarity value exceeding a preset value to the data providing client, so the teacher may know the plagiarism situation of student homework fast.
