Description
Technical field
The present invention relates to online teaching fields, reserve system more particularly, to a kind of course of Online Video tutoring system
System.
Background technique
With the development of internet technology, online teaching platform development is very rapid, and video teaching becomes instantly most popular
Online teaching mode.Existing video teaching can be one-to-many, be also possible to one-to-one, and student and teacher resource are abundant,
How to realize and realizes that the personalized customization of teacher, course become the research weight of internet online teaching according to the demand of student
Point.
Summary of the invention
The present invention in order to overcome at least one of the drawbacks of the prior art described above (deficiency), provides a kind of one-to-one religion of realization
Learn the course reservation system of the Online Video tutoring system of the online reservation function of course.
In order to solve the above technical problems, technical scheme is as follows:
A kind of course reservation system of Online Video tutoring system, the system comprises teaching platforms；Teaching platform is equipped with teacher
Resource database stores the information that all teachers are associated with course with teacher；Teaching platform is equipped with student's lesson data library, stores institute
The curriculum schedule for having the online teaching content of student and being formulated according to online teaching content；
Teaching platform is specifically used for:
After the course completion information for receiving Students ' Feedback, the curriculum schedule for extracting the student determines the course next time of student；
It is searched for from teacher resource database according to the course next time of student and the associated teacher of course and this is old next time
Teacher correspond to this next time the course time form reservation information table and the reservation information table be sent to the account of corresponding student；
Receive teacher and the time of the course next time reserved according to reservation information table that student uploads；
According to the teacher of student reservation and time, updates teacher resource database and the subscription time is sent to the student's
Teacher's account of student account and selected teacher.
System of the invention can configure corresponding reservation information table according to the study schedule of student and carry out course to student
Reservation, and Relational database is updated according to the course reservation information of Students ' Feedback and pushes to student account and teacher's account, it is real
The one-to-one course reservation function of present line video teaching facilitates student to be arranged flexibly to carry out the pre- of course according to temporal
About, the flexibility of Online Video study is improved.
In above scheme, the course time that teacher uploads is received, updates the course time of teacher in teacher resource database.
In above scheme, teaching platform is additionally provided with teacher's recommender system；
Teacher's recommender system, which is equipped with, is stored with teacher's selection application form that student selects teacher's hobby, and teacher selects to set in application form
There are gender, educational background, the selection of three attribute of age；
Teaching platform extracts the attribute information of searched teacher, extracted attribute is believed when forming reservation information table
The teacher of breath and the student select application form to match, if the selection of any attribute information and student are matched, assigning should
The value of attribute information is attribute coefficients, and attribute coefficients are greater than 1, and the value for otherwise assigning the attribute information is 1；If three attribute informations
Value be σ 1, σ 2, σ 3；
That teaching platform calculates the value of the attribute information of all teachers searched and β, i.e. 3=β of σ 1+ σ 2+ σ；In reservation information table
In, teacher put in order according to attribute information value and β arrange from big to small.
In above scheme, teacher's recommender system also particularly useful for:
It extracts student and the corresponding teacher's attribute information of course is completed, add up selected in each attribute information and teacher's selection application form
Matching times；If matching times are greater than certain threshold value, assigning the attributes match coefficient Φ is matching value, and matching value is greater than 1,
Otherwise assigning the attributes match coefficient Φ is 1；
When teaching platform explicit reservation information table, first by the value of each attribute information multiplied by corresponding attributes match coefficient Φ, then
Summation, i.e. σ 1* Φ 1+ σ 2* Φ 2+ σ 3* Φ 3, Φ 1, Φ 2, Φ 3 respectively indicate the matching factor of three attribute informations, then will
Putting in order for teacher arranges from big to small according to σ 1* Φ 1+ σ 2* Φ 2+ σ 3* Φ 3 in reservation information table.
In above scheme, teacher's recommender system also particularly useful for:
History scoring μ is obtained score value λ multiplied by scoring coefficient by the history scoring μ for extracting searched teacher；History scoring
Score value can be set according to different application systems, and scoring coefficient is arranged according to the actual situation.
When 101 explicit reservation information table of teaching platform, teacher puts in order there are three types of optional way in reservation information table:
It arranged, arranged from big to small according to μ, according to σ 1* Φ 1+ σ 2* Φ 2+ σ 3* from big to small according to σ 1* Φ 1+ σ 2* Φ 2+ σ 3* Φ 3
The value of Φ 3+ λ arranges from big to small.
In above scheme, teacher's recommender system also particularly useful for:
The experience with students of searched teacher is extracted, the experience with students includes impart knowledge to students under line year N and online teaching course
Number K；
When teaching platform explicit reservation information table, putting in order for teacher has 6 kinds of optional ways in reservation information table: according to σ 1*
Φ 1+ σ 2* Φ 2+ σ 3* Φ 3 is arranged, is arranged from big to small according to μ, from big to small according to σ 1* Φ 1+ σ 2* Φ 2+ σ 3* Φ 3+ λ's
Be worth arrangement from big to small, arranged according to the year N that imparts knowledge to students under line, arranged from big to small according to online teaching course number K from big to small,
It is arranged from big to small according to σ 1* Φ 1+ σ 2* Φ 2+ σ 3* Φ 3+ λ+N*N1+K*K1；Wherein N1 and K1 is experience with students system respectively
Number, experience with students coefficient are respectively less than 1.
In above scheme, teacher's recommender system also particularly useful for:
Course precession time is set in reservation information table；
Calculate how far value T of the course time from course precession time selected by student of each teacher in reservation information table；
When explicit reservation information table, putting in order for teacher has 8 kinds of optional ways in reservation information table: according to σ 1* Φ 1+ σ 2* Φ
2+ σ 3* Φ 3 arranges from big to small, arranged from big to small according to μ, according to the value of σ 1* Φ 1+ σ 2* Φ 2+ σ 3* Φ 3+ λ from big to small
Arrangement is arranged from big to small according to the year N that imparts knowledge to students under line, is arranged from big to small, according to online teaching course number K according to σ 1* Φ 1
+ σ 2* Φ 2+ σ 3* Φ 3+ λ+N*N1+K*K1 is arranged, is arranged from small to large according to T, from big to small according to σ 1* Φ 1+ σ 2* Φ 2+ σ
3* Φ 3+ λ+N*N1+K*K-T is arranged from small to large.
Compared with prior art, the beneficial effect of technical solution of the present invention is:
System of the invention can configure corresponding reservation information table according to the study schedule of student and carry out course reservation to student,
And Relational database is updated according to the course reservation information of Students ' Feedback and pushes to student account and teacher's account, it realizes online
The one-to-one course reservation function of video teaching facilitates student to arrange the reservation for flexibly carrying out course according to temporal, improves
The flexibility of Online Video study.
