Line, face, arithmetic.After prolong knowledge point：Areal calculation etc..The control terminal starts to set a question according to these information：
The achievement for getting the student first is common, therefore select file condition code is set as junior middle school 2 years from exam pool
Level, knowledge point is for quadrangle and knowledge point requires to be degree of understanding, and remaining adjacent knowledge point requires to be the degree of understanding.This is set
Total answer number 15 of secondary exercise is inscribed, and control terminal will be grouped automatically, 15 topics is divided into first group 10 and is inscribed and is inscribed with second group 5.Every group
In exercise question all include identical knowledge point.First group of answer of exercise question is first carried out after beginning, from choosing in exercise database
Go out the file with correspondence knowledge point file eigenvalue, show exercise question in interactive interface one by one for student's answer, student has solved
Control terminal will determine that whether the answer is correct during one exercise question, and will determine that result is temporarily stored in the interim of control terminal and deposits
In storage unit.
First group 10 topic in it is preceding 8 topic in the student done wrong 2 topic, and skipped 1 topic.It is last that for skipping inscribes the student
Return and answer correct.But still assert that preceding 8 problem purpose false answer reaches 3 topics according to decision condition.Now control terminal
Start analysis, find the mistake of the student because mistake in computation, but to the acquistion of concept of quadrangle still in place, therefore
First group will reduce the difficulty in computation set a question, the preposition knowledge point without tracing back to quadrangle when the 9th topic and the 10th topic is gone out.
After the completion of first group, any influence will not be brought on second group, second group of exercise question 5 is inscribed and gone out according further to initial
Topic rule is set a question.Due to not being quota 10 inscribe, therefore second group of difficulty will not change.Will meter after being finally completed
Calculate student's the final result.Because first group of last twice exercise question is reduction of difficulty, thus when fraction is calculated except
Subtract outside the fraction of the twice exercise question for doing wrong, a weighting will be also carried out to overall fraction so that final fractional matching
Raw real result.But shown also according to true score in display, will simply have been recorded when student data is updated.
Embodiment 2：
The student that primary school is 3 grades is, it is necessary to carry out mental arithmetic exercise exercise.He is opened as the computer of interactive interface, is logged in
Personal account, control terminal obtains the personal information of the student, and each side attribute.
The student selects verbal exercise, contains arithmetic.Exercise question quantity selection 100 is inscribed.
Exercise in exercise database is preserved in the form of individual files, has file eigenvalue in each file.
Exercise involved in the present embodiment is needed with following file eigenvalue：The knowledge point covered：Double figures arithmetic.
The throughput for needing to have：Addition, subtraction, multiplication, division are required to reach the degree that understand and can calculate.Student oriented
Scope：Primary school 2-4 grades.Adjoining knowledge point wherein related to the exercise knowledge point includes parallel knowledge point：Order of operation, include
Number effect etc.；Preposition knowledge point includes：Units arithmetic, multiplication formula table.After prolong knowledge point：The four fundamental rules fortune of 3 digits
Calculate.The control terminal starts to set a question according to these information：
The achievement for getting the student first is poor, therefore select file condition code is set as primary school 3 years from exam pool
Level, knowledge point is set to double figures arithmetic and difficulty is to understand.The total answer number 100 for setting this exercise is inscribed, and control is eventually
End will be grouped automatically, and 100 topics are divided into 10 groups, and every group 10 is inscribed.First group of answer of exercise question is first carried out after beginning, from exercise
The file with correspondence knowledge point file eigenvalue is selected in database, shows that exercise question is answered for student in interactive interface one by one
Topic, control terminal will determine that whether the answer is correct when student has solved one exercise question, and will determine that result is temporarily stored in control
In the temporary storage cell of terminal.Due to being to be related to mental arithmetic to calculate quickly, therefore also judge with timing, per pass exercise question exceedes estimated meter
Evaluation time, is still judged as erroneous answers in control terminal.
First group 10 topic in it is preceding 8 topic in the student done wrong 3 topic, and have 2 topics time-out.Still assert according to decision condition
Preceding 8 problem purpose false answer reaches 5 topics.Now control terminal starts analysis, finds the mistake of the student because for multiplying
Method is unfamiliar with, but to the grasp of addition and subtraction preferably, therefore first group will trace back to four fundamental rules fortune when the 9th topic and the 10th topic is being gone out
The preposition knowledge point calculated, i.e., the 9th topic and the 10th topic are both configured to units multiplication.Student is so on the one hand allowed to review lower basis,
The wrong too many enthusiasm for causing student to lose study is also avoided simultaneously.
After the completion of first group, any influence will not be brought on second group, second group of exercise question 10 is inscribed still using such
Method, by that analogy to last.
Student's the final result will be calculated after being finally completed.Because first group of last twice exercise question is reduction of difficulty
, therefore when fraction is calculated in addition to subtracting the 3 problem purpose fractions for doing wrong, a weighting will be also carried out to overall fraction,
So that the real result of the final fractional matching student.But shown also according to true score in display, simply more
To be recorded during new student data.The achievement of so final display is relatively more good-looking, while also to the basis of student itself
It has been made up that, taken into account the demand of education side and study side.
Relative, if student all answers correct during answer, difficulty can be increased in two problems of adjustment,
Challenged to top student.
In the judgement that final knowledge point is grasped, using formula P (θ)=1/ (1+e^ (- θ)), wherein θ represents that evaluation is learned
Raw ability parameter；B represents the difficulty number of each exercise question；P (θ) represents assessment of students' for probability that the knowledge point is grasped；E is
Constant.
The wherein computational methods of θ are to choose nearest 100 topic in the knowledge point, calculate ln (correct dependent factor V's and/it is wrong
The sum of dependent factor V) by mistake.It is better that P (θ) illustrates that the knowledge point is grasped closer to 1.
But the judgement due to system to knowledge point is all relatively objective evaluation, therefore present system is typically only capable to use
In mathematics, and it is not appropriate for for the subject of the subjectivity answer such as Chinese language, English.Meanwhile, this set question-setting system is suitable for exercise to be made
With, and be not suitable for examination and use.
