It is understood that the object knowledge point may be covered in the candidate exercise, it is also possible to cover in institute
It states in exam pool in other exercises.Each exercise (including time of the object knowledge point will be covered in the exam pool
Select exercise) it is set as the exercise that is mutually related.
S2, the association exercise set that the candidate exercise is determined according to the object knowledge point, obtain in database
First history accuracy rate of the learner of storage when answering the association exercise set；According to the first history accuracy rate
Obtain ability value.
Wherein, the association exercise set includes at least two association exercises, and the entitled topic is practiced in the association
Cover the exercise of the object knowledge point in library.The ability value is for assessing the learner to the object knowledge point
Grasp ability.The learner is any learner in learner's set.
It is described that ability value is obtained according to the first history accuracy rate in step S2 in some embodiments, it is specific to wrap
It includes: the first history accuracy rate is arranged to force value.
In some embodiments, the expression formula of the ability value are as follows:
C=P2 (1)
Wherein, C is the ability value；P2For first history of the learner when answering the association exercise set
Accuracy rate.
Learner, can be by learner in the first history when being associated with exercise set of answering to the Grasping level of knowledge point
Accuracy rate makes effective assessment.Association exercise set, which is equivalent to, investigates the examination that learner grasps ability to object knowledge point
Volume, learner is higher in the first history accuracy rate when being associated with exercise set of answering, and illustrates grasp of the learner to knowledge point
Situation is higher.
Learner has certain palm to object knowledge point after having learnt blocks of knowledge corresponding with object knowledge point
It holds, at this point, exercise recommendation apparatus recommends several preset primary exercises for being easy to answer to learner, is learned to investigate
Grasp situation of the habit person to object knowledge point.Exercise recommendation apparatus by learner answer whole primary exercises when it is correct
Rate obtains initial ability value according to the first history accuracy rate as the first initial history accuracy rate.Exercise is recommended
Equipment stores the initial ability value in the database.Also, exercise recommendation apparatus is according to association of answering after learner
Accuracy when exercise set, the ability value in real-time update database, to keep assessment learner to slap object knowledge point
Hold the accuracy of ability.
The the first history accuracy rate of the ability value and the learner when answering each association exercise set is in
It is positively correlated.
The learner trained may cross the pass of the candidate exercise before the candidate exercise of answering
Join exercise.The learner is able to reflect out the learner couple in the first history accuracy rate when being associated with exercise of answering
The grasp situation of the object knowledge point.The i.e. described learner is higher in the first history accuracy rate when being associated with exercise of answering,
Then illustrate that the Grasping level of the point of object knowledge described in the learner is also higher.
Optionally, the course relevant with the object knowledge point that the ability value had also been learned to the learner into
Degree is positively correlated.
The course that the learner had learned may includes the related content of the object knowledge point, in this way,
Habit person has certain grasp to the object knowledge point before the topic that do not do one's exercises.In general, the learner has learned
The course relevant to the object knowledge point crossed is more, then the learner to the Grasping level of the object knowledge point also
It is higher.
In some embodiments, in step S2, the pass that the candidate exercise is determined according to the object knowledge point
Join exercise set, specifically include:
It obtains target practice in the exam pool and inscribes covered knowledge point；Appointing in the entitled exam pool of target practice
One exercise；Covered knowledge point is inscribed in the target practice to match with the object knowledge point；If successful match,
The association exercise is set by target practice topic, finally obtains the association exercise set.
S3, the corresponding difficulty value of the object knowledge point is obtained, calculates the difference between the ability value and the difficulty value
Absolute value, if the absolute value of the difference is less than or equal to preset threshold value, by the candidate exercise labeled as recommending to practice
Exercise.
The entitled exercise for being suitble to the learner to answer is practiced in the recommendation.
The threshold value is for measuring complexity of the object knowledge point for the learner.If the difference
Absolute value be less than or equal to preset threshold value, then illustrate that the deviation between the ability value and the difficulty value is smaller, it is described
For object knowledge point for the learner, difficulty is moderate, compares and the learner is suitble to answer.In the absolute of the difference
Value is less than or equal in the state of preset threshold value, when the ability value is greater than the difficulty value, illustrates the object knowledge
Point is slightly difficult for the learner, when the ability value is less than the difficulty value, illustrates the object knowledge point phase
It is slightly simple for the learner.In this way, the difficulty value and the ability value are effectively filtered out relative to described
The moderate recommendation exercise set of learner's difficulty, rationally recommends exercise to be embodied as the learner.
In some embodiments, before step S1, after step S013, further comprising the steps of S031-S032:
The learner stored in S031, the acquisition database is integrated into the answer candidate exercise and the association
The second history accuracy rate when exercise set；The second history accuracy rate is set as the corresponding standard of the object knowledge point
True rate.
Exercise recommendation apparatus records the result of answering for the exercise that each learner did.Count learner's collection
The second history accuracy rate when answering the candidate exercise and each association exercise set is closed, institute has also just been obtained
State learner set answer in the past the object knowledge point when accuracy rate.Because candidate's exercise or the association are practised
Topic is answered questions, then the object knowledge point covered also just is answered questions.The accuracy rate of the object knowledge point is institute
State the ratio of the total degree that object knowledge point was answered questions in the past Yu the total degree answered in the past.
S032, according to the corresponding accuracy rate of the object knowledge point, the corresponding difficulty of the object knowledge point is set
Value.
It is understood that the corresponding accuracy rate of the object knowledge point is higher, illustrate the difficulty of the object knowledge point
Lower, therefore, difficulty value accuracy rate corresponding with the object knowledge point is negatively correlated.Exercise recommendation apparatus will be described
Difficulty value stores in the database.As the association exercise that learner's set was done is more and more, learner gathers pass of answering
Accuracy rate when joining exercise set can constantly change, i.e., the difficulty value of the described object knowledge point can constantly change, practice
The difficulty value of recommendation apparatus object knowledge point according to the second history accuracy rate real-time update is inscribed, to guarantee the object knowledge
The accuracy of the difficulty value of point.
In some embodiments, the expression formula of the difficulty value are as follows:
H=(1-P1)*i； (2)
Wherein, H is the difficulty value；P1For the corresponding accuracy rate of the object knowledge point；I is constant, 0 < i≤1.
It is to be understood that i is for adjusting the difficulty value H.Because some when, the palm of the learner to knowledge point
It holds degree and is although not enough to answer the biggish knowledge point of difficulty, but often do ' lifting ' training, i.e., specially do some difficulty
Biggish exercise, to improve oneself grasp ability to knowledge point.For this purpose, the application can suitably be dropped using the constant i less than 1
The low difficulty value H ' is pulled out for the exercise that learner suitably recommends actual difficulty more slightly higher than the Grasping level of learner with reaching
The purpose of height ' training.
For example, it is assumed that i=95%, if the corresponding accuracy rate of object knowledge point is 75%, the object knowledge
The corresponding difficulty value of point is set as (1-75%) * 95%；If the corresponding accuracy rate of the object knowledge point is 20%,
The corresponding difficulty value of the object knowledge point is set as (1-20%) * 95%.
In above embodiment, the difficulty value C in the ability value H and expression formula (1) in expression formula (2) is equal
For the numerical value in [0,1] section, correspondingly, the absolute value of the difference is also the numerical value in [0,1] section.The ability value and
The difficulty value is that the accuracy rate inscribed of doing of foundation learner obtains, and has good objectivity and authenticity, Neng Gouke
Sight is that the learner filters out suitable exercise and answers.
For example, it is assumed that the threshold value J=5%, the ability value C of the learner is 70%；And assume i=100%,
The corresponding accuracy rate P of the object knowledge point1It is 20%, in this way, obtaining the difficulty value H is 80% according to expression formula (2)；
Due to | C-H |=| 70%-80% |=10% > J, i.e., absolute value of the difference is more than between the described ability value C and the difficulty value H
Therefore the threshold value J determines that the candidate exercise is not suitable for the learner and answers.In the example, the object knowledge point
Corresponding accuracy rate P1Only 20%, it is seen that the object knowledge point is that comparison is difficult for most of learners,
The ability value C of habit person is 70%, and ability is much larger than accuracy rate P1, illustrate the learner to the palm of the object knowledge point
It is more much higher than the grasp ability of most of learners to hold ability, nonetheless, due to | C-H | > J illustrates the candidate practice
The difficulty of topic has been more than preset interval range for the learner, this is easy to expend the learner more
Reaction time is lost more than gain, and therefore, determines that the candidate exercise is not suitable for the learner and answers.Likewise, if described
The difficulty of candidate exercise is too simple for the learner, is similarly not suitable for the learner and currently continues to make
It answers, because too simple exercise is limited to the ability raising of learner, wastes the time of learner.
In some embodiments, before step S1, include the following steps S031:
S031, using the corresponding difficulty value in each knowledge point in the knowledge point set as element, establish difficulty value sequence；With
And using the learner relative to each knowledge point in the knowledge point set ability value as element, capacity-building value sequence.
The each element in each element and the ability value sequence in the difficulty value sequence corresponds.
For example, with the linear algebra in College Maths for the blocks of knowledge, it is assumed that the knowledge point set of the blocks of knowledge
Quantity k=5 in knowledge point in conjunction is inscribed according to learner is previous as a result, sampling out the ability value sequence for the learner that number is i
α _ i=(0.2,0.3,0.8,0.2,0), wherein each numerical value respectively indicates learner to the Grasping level of each knowledge point, knowledge point
Corresponding numerical value is bigger, illustrates that learner is higher to the Grasping level of knowledge point.It is assumed that the difficulty value for the exercise that number is j
Sequence q_j=(0.4,0,0.6,0.2,0), wherein each numerical value respectively indicates the difficulty of each knowledge point in exercise, knowledge point pair
The numerical value answered is bigger, and difficulty is higher.In difficulty value sequence q_j, the knowledge point that difficulty value is 0 indicates to number the exercise for being j not
Cover the knowledge point.That is, the exercise that number is j covers 3 knowledge points in knowledge point set, i.e., number is
The exercise of j has 3 object knowledge points, and difficulty value is respectively 0.4,0.6 and 0.2.
In some embodiments, the object knowledge point in candidate's exercise has multiple.From the difficulty value sequence
The difficulty value corresponding to each object knowledge point in the candidate exercise is extracted in column.From the ability value sequence
Middle extraction and each ability value corresponding to each object knowledge point in the candidate exercise.Step S3 includes following
Step: the absolute of the difference corresponding to each object knowledge point between the ability value and the difficulty value is calculated separately
Value practices the candidate exercise labeled as the recommendation if each absolute value of the difference is respectively less than or is equal to the threshold value
Exercise.
S4, several recommendation exercises are obtained from the exam pool, the recommendation exercise is pushed into
The answer interface of habit person.
In above-described embodiment, by the way that the ability value compared with the difficulty value, is obtained several from exam pool and is pushed away
Exercise is recommended, exercise will be recommended to recommend the learner；Accuracy rate according to learner's answer constantly updates learner's phase
For the ability value of knowledge point, as the learner grasps the raising of ability to knowledge point, the recommendation exercise recommended
Difficulty also steps up so that the learner when doing Training of Exercises, follow it is progressive, can gradually, effectively improve it is described
Grasp ability of the learner to knowledge point.
