Description
Technical field
The present invention relates to a kind of system for automatically generating test report, it belongs to the technical field of educational assessment.
Background technology
In order to which the comprehensive quality of students state of development scientifically to each term is implemented to test and assess, what we inscribed emphatically to survey etc.
Valency has carried out systematic research, in our measurement system, mark two part survey topic index of equal value, there is two, and one is to survey
The approach degree of topic, two be the intelligent total value of survey topic.Tested with survey of equal value topic, to be finally presented to student, parent, religion
Teacher, leader etc. adapt to the test and evaluation report of various role people.Although we determined that the quantitative criteria of academic assessment, to learning
Raw individual or student place class, school group, the result of test are required for informing test result, that is, to provide test and appraisal report
Accuse.Automation produces test and evaluation report, and we encounter three stubborn problems.
First, how intelligent total value is converted to volume face point
Second, how intelligent total value is turned or to examine comparable site index withStudent's participation is any once to take an examination,
Parent pays close attention to the marks sequencing situation of child, and " which our child examinesOur child can be admitted to emphasis senior middle school" this
It is the frequent concern of numerous parents.
3rd, how the data that test is obtained can in time be understood, allow and take one's test in the test report generated in time
People understand data behind reflection the problem ofDuring educational assessment is implemented, object always to be evaluated draws qualitative
Evaluation conclusion.(the n when the object being evaluated is more>30) qualitative evaluation conclusion portion, is manually write out than larger
Workload.Artificial operation, writes comment, it is easy to produce mindset by teacher in addition, it is difficult to which the student of internal each level is learning
The evaluation for meeting objective reality is made on Xishui County is flat.Some teachers do not write comment simply, only give one exam score of student.Student
A fraction for not knowing its meaning has been taken, it is actually how unknown in effort to follow-up study.Educational assessment is
Regulation and control student, Jiao Shijiao, the process being subjected to run a school etc. is managed, if educational assessment can not provide objective and fair
Appropriate comment, it is impossible to be provided the comment of directiveness by the person of commenting, also just loses the effect evaluated and be oriented to commander.Furthermore say,
Comment in educational assessment, will have promptness, just have effect to student.It is belated if just providing report by half a year or 1 year
Test and appraisal conclusion can not be in time not only student, parent, teacher provide school work useful information, it is more likely that cause original ask
Topic is serious.
The content of the invention
To solve problems of the prior art, the present invention provides a kind of system for automatically generating test report, with up to
To following purpose：Smart index is converted into test paper score, obtain examining during total marks of the examination are in or the site index in college entrance examination,
The evaluation of the advantage or problem of intelligent key element study is provided, and the compensation of specific aim survey topic is carried out to problem；Students ' Learning is risen
To targetedly instructing.
The technical solution adopted by the present invention is：A kind of system for automatically generating test report, the system include exam pool module,
Survey evaluation module, compensating module, volume face point modular converter and site index module；
The exam pool module is that the progress corresponding with teaching material of the curricular standard of various courses is known into energy goal decomposition, and establishment is surveyed
Try each level and know that each level survey that can be put is inscribed and determines the smart index of survey topic；Each survey topic matrix M is constituted, in matrix M
Each element, is all that the test of one of Ce Tihezhe roads survey topic knows that the disjunctor that can be put is represented；Single topic in survey topic matrix MWherein x represents knowledge classification, and y, which is represented, knows energy point, i.e., know that energy key element solves certain problem with certain；R singly inscribes for this
Smart index；
For example, being a certain single topic in exam pool matrix below：
(several computings)
(the relation knowledge of dividend in division, divisor, business and remainder is used, the ability of division calculation is solved the problems, such as.) 1、
Maximum fills out several in 43 ÷ 8=... () brackets(r=3)
A、5 B、6 C、10 D、7
X is knowledge classification, i.e. several computings；Y for know can point, i.e., with dividend in division, divisor, business and remainder
Relation knowledge, solves the problems, such as the ability of division calculation.The smart index that r singly inscribes for this, r=3.The evaluation module is according to
Life is answered to survey topic, and the advantage speciality and problem of knowing energy key element of analysis student are presented；
If student inscribes on answering, answer questions and then record y values to speciality area, and record, count corresponding r values；R values are used
Modular converter in subsequently volume face point；Y values are recorded if mistake is answered to problem area；And count knowing under same knowledge classification can point
Answer, make record.
For example, (1) under the sorting of operation of number uses the relation knowledge of dividend in division, divisor, business and remainder, solve
The ability of division calculation problem；(2) method knowledge of the estimation of number is used, the ability of simple estimation application problem is solved；Etc..
The compensating module is that can be presented according to knowing for student the problem of key element, and the survey that this knows energy key element is extracted in compensation
Topic, to be used as compensation exercise；
For example：Know can key element be dividend, divisor, relation of business and remainder etc. in division.
The volume face point modular converter is that the smart index for inscribing per pass survey is converted into corresponding test paper score, per problem
Test paper score be a whole set of survey topic volume face total score be multiplied by the smart index of per pass survey topic and a whole set of survey inscribe smart index and ratio；
I.e.：
F among these is the fraction after each problem conversion during survey is inscribed；Z is the smart index of each problem in survey topic；
It is the smart index sum of each problem in a whole set of survey topic；J is jth problem in a whole set of examination question, and n is the whole series
Total topic number of examination question；
The site index module be used for calculate this examination question fraction account in examine or college entrance examination in corresponding section's purpose fraction；
The calculation formula of site index is：
Z1Take one's test the intelligent total value answered and paid for student；Z0The normal of intelligent total value is inscribed for some subject survey
Modulus value；F is that some subject survey topic expects full marks；τ is examination question approach degree, 0<τ<1；R is course redundancy, and r is 0.15；
Beneficial effects of the present invention are：By intelligent total value change come fraction, substantially reduce evaluation quantizing process
Randomness, the fraction obtained by student be mark pay intellectual work by the quantized values reduced in proportion.This can be right
The result of students in middle and primary schools' items quality assessment is presented in same overall structure in proportion.Site index can describe to learn exactly
Test score, i.e., turned core Cheng Yuzhong examination mark number ranking pars by the raw ranking for participating in test result in colony, is had
There is the numerical value of comparativity.The evaluation of the advantage or problem of intelligent key element study is provided in real time, and specific aim survey topic is carried out to problem
Compensation；Students ' Learning is played and targetedly instructed.
Figure of description
Fig. 1 is automatically generated the sectional drawing of survey topic report.
Fig. 2 is automatically generated the sectional drawing of survey topic report.
Embodiment
The smart index of embodiment 1 is converted into test paper score
Each problem that we extract out in automation exam pool all carries smart index, and every suit survey topic of composition is all certainly
It is dynamic with intelligent total value, and intelligent total value mark is how much student's this set survey topic of answering needs the intellectual work paid.
Traditional academic assessment quantization method, is divided first to each problem assign, and regulation volume face full marks are how many, are made
Answer examination question and see how many points；We from automatically generate survey topic system in extract survey topic, the smart index of each problem and
The intelligent total value of a whole set of survey topic is converted into fraction feasibilityOur conclusions after demonstration are feasible.Ours goes out
The smart index of every problem be converted to the formula of fraction and be:
F among these1, f2, f3... ..., fnIt is the fraction during survey is inscribed after each problem conversion；
Z1,Z2,Z3... Zn is the smart index of each problem in survey topic；
It is the smart index sum of each problem in a whole set of survey topic.
f1+f2+f3……fn=M
M is the volume face total score after the intelligent total value conversion of a whole set of survey topic.
With this formula, we can inscribe any a set of survey of any one subject, from can with " intelligent total value "
With change into 150 points, change into 120 points, change into 100 points, change into 80 points ..., may switch to the score value of any needs.
So by intelligent total value change come fraction, substantially reduce evaluation quantizing process randomness, Xue Shengsuo
Fraction be mark pay intellectual work by the quantized values reduced in proportion.There is such conversion method, can be
Result to the every quality assessment of students in middle and primary schools is presented in same overall structure in proportion.This to analyze course offered section
The property learned is undoubtedly a breakthrough creation.
Our this set algorithm, applies in full-automatic item banking, can meet at different levels, various kinds of schools, all kinds
Examination, both retained the score form of traditional habit, make that the score value of every problem represents again is smart index turning in proportion
Change value.
With this formula, we can inscribe any a set of survey of any one subject, are transformed into from " intelligence "
The score value needed with any one.
Table 1 is 10 sets of topic smart index statistical forms, and table 2 is that this 10 sets topic smart indexes change system with 100 number scorings
Table is counted, we amount to the mean error calculated in the such score value conversion of 30 sets of topic progress, 660 data and are less than 8/10000ths, can
To ignore.Table 3 is same set of topic, is respectively converted into 150 points, 120 points, 100 points, 80 points of conversion value comparison table.

When carrying out overall qualities test and appraisal to student, not only school work test and appraisal need survey topic of equal value, to the characteristics of personality of student
Test and appraisal, are tested and assessed to temperament type, and physical culture is tested and assessed, and morality development level is tested and assessed, is required for the survey with equivalence to inscribe,
Could meet Test Reliability, validity, unification.The developing the quality level in terms of which no matter is tested, is test after all
The development level of intelligent factors, therefore, this set algorithm are also that during overall qualities are tested and assessed, other quality of testing and assessing also relate to fraction
Transfer problem, can solve problem using this set algorithm.
The calculating of the site index of embodiment 2
1st, the intelligent total value of branch is converted to the algorithm model of site index
Student's participation is any once to take an examination, and parent pays close attention to the marks sequencing situation of child, and " which our child examines
Our child can be admitted to emphasis senior middle school" this is the frequent concern of numerous parents.Parent is answered with the property expected
It is compared, should be discharged to student single on query, the horizontal line that we examine during the achievement taken an examination each time is all moved to
Section and the position of total score, will also accuse and state parent, " it is what kind of that your child compares with middle examination mark number then ".
Ranking of the test result in colony is participated in order to be able to describe student exactly, and compared with middle examination mark number
Situation, we inscribe the survey that student participates in test the intelligent total value norm phase of intelligent total value subject corresponding to being examined in this area
Compare, i.e., test score is turned core Cheng Yuzhong examination mark number ranking pars, the numerical value with comparativity, we are this numerical value
It is called " site index ".
We pass through the Shenyang to our province, Daliang City of city, Anshan, Liaoyang City, Yingkou City, Jinzhou City, Benxi, Tieling
Each subject survey topic research of the area such as city, Huludao City first rise of nearly 5 years, the smart index to every problem is audited, obtained
The mode of the intelligent total value of survey topic is raised in Chinese language, mathematics, the section of English three at the beginning of each section, intelligence is inscribed as survey is raised at the beginning of our province
The norm of energy total value, following conversion formula is set up with this：
Z1--- student takes one's test the intelligent total value answered and paid；
Z0--- just raise the norm value of the intelligent total value of some subject survey topic；
F --- just raise some subject survey topic and expect full marks；
τ --- examination question approach degree；
R --- course redundancy (often touches determination according to target, at present for 0.15)
Example：One senior class pupil participates in mathematics test, and the smart value for answering questions topic adds up to 189, the patch of survey topic
Recency is 0.8, in examine mathematics volume face full marks 150, the intelligent total value of just rise mathematics survey topic often touches value 321
2nd, multidisciplinary average status exponentiation algorithm model
We according to but convertible formula and average weighted thought have constructed the algorithm model of average site index.
Z11……1n--- student participates in each section and tests the intelligent total value answered and paid respectively
Z01……0n--- the norm value of the intelligent total value of survey topic is raised at the beginning of Ge Ke sections；
f1~fn--- participate in each subject survey topic full marks desired value of computing；
f01~f0n--- participate in the intelligent total value of each subject survey topic (volume face) of test；
f11~f1n--- student participates in each subject of test and answered (actually obtaining) intelligent total value of acquisition
τ1……n--- participate in computing subject survey topic approach degree；
R --- course redundancy (often touches determination according to target, at present for 0.15)
For example：Certain student, has participated in primary school Chinese, mathematics, the test of English end of term next term, and the answer of three sections is paid
Intelligent total value is respectively Chinese language Z11=286, mathematics Z12=272, foreign language Z13=231；
Survey topic approach degree is respectively Chinese language τ1=0.82 mathematics τ2=0.79, foreign language τ3=0.87
Each subject of this student is answered obtained intelligent total value
The norm value Chinese language Z of the intelligent total value of just rise survey topic01=318, mathematics Z02=321, English Z03=298
Just rise survey topic Chinese language f1=150, mathematics f2=150, English written examination f3=140, the average status of this student refers to
Number
Embodiment 3 automatically generates comment
During educational assessment is implemented, object always to be evaluated draws qualitatively evaluation conclusion.When being evaluated
Object it is more when (n>30), manually write out qualitative evaluation conclusion be exactly portion than larger workload.Artificial operation in addition,
Comment is write by teacher, it is easy to produce mindset, it is difficult to which the student of internal each level makes on learning level meets objective
Actual evaluation.Some teachers do not write comment simply, only give one exam score of student.Student has taken one and has not known its meaning
Fraction, to follow-up study, actually how make great efforts it is unknown.Educational assessment is regulation and control student, Jiao Shijiao, neck
The process being subjected to that conduit reason is run a school etc., if educational assessment can not provide objective and fair appropriate comment, it is impossible to be quilt
The person of commenting provides the comment of directiveness, also just loses the effect evaluated and be oriented to commander.Furthermore say that comment in educational assessment will have
There is promptness, just have effect to student.If just providing report by half a year or 1 year, belated test and appraisal conclusion not only can not
There is provided school work useful information for student, parent, teacher in time, it is more likely that the problem of causing original is serious.
In order to obtain the comment of directive significance in time to the report of the academic assessment of student, we construct educational assessment
Comment gathers automatic creation system.
The first step, we first know the curricular standard progress corresponding with teaching material of various courses can goal decomposition；
Second step, each level of establishment test knows each level survey topic that can be put.
Illustrate：
Each survey topic matrix M is constituted, each element in matrix M is all the test of one of Ce Tihezhe roads survey topic
The disjunctor that knowing to put is represented.Element representation in each M is added top mark form into the truth of a matter, new survey topic matrix A is constituted
Further according to partitioning of matrix principle of operation, element in element composition matrix A in matrix A ', and by matrix A ' is randomly selected
Top mark, constitutes matrix A ", after student answers to the survey topic in A', just there is dividing to mistake, we according to the answer situation of student,
To student know can key element separate and belong to advantage speciality and problem and present, dotted state and mistake when accordingly to the school work of individual students
Journey state is made an appraisal.
Note：
The synchronous class hour that j ... represents every subjects is total (or unit number)；
N ... represents every subjects and knows energy key element sum；
m1m2m3m4…………mn,
b1b2……bn,c1c2c3……cn,
d1d2d3d4……dn,
……,
……,
t1t2t3……tn
These represent that every problem investigated respectively corresponding know can key element.
FromN element in take x1Individual element, there is Cx nPlant possible outcome
(using 0 occupy-place when not taking in centre)；
FromN element in take x2Element, there is Cx nPlant possible outcome
(using 0 occupy-place when not taking in centre)；
FromN element in take x3Individual element, there is Cx nPlant possible outcome
(using 0 occupy-place when not taking in centre)；
……
……
FromN element in take xjIndividual element, there is Cx nPlant possible outcome
(using 0 occupy-place when not taking in centre)；The piecemeal submatrix A' of matrix A is constituted, then
Each element in matrix in block form A', the top mark for being each element in the survey topic drawn, A' is respectively a survey
What each problem in topic was checked and examined knows the combination of energy key element or a few Xiang Zhineng key elements.What the top mark of each topic drawn was constituted
Matrix is:
The exam pool module is that the progress corresponding with teaching material of the curricular standard of various courses is known into energy goal decomposition, and establishment is surveyed
Try each level and know that each level survey that can be put is inscribed and determines the smart index of survey topic；Each survey topic matrix M is constituted, in matrix M

Y values are recorded to speciality area, and records, count corresponding r values；Modular converter of the r values for follow-up volume face point；Remember if mistake is answered
Y values are recorded to problem area；And count under same knowledge classification knowing can point answer, make record.Student, may when answering
Answer questions, it is also possible to answer mistake, answer questions show be use knowledge problem-solving ability advantage；Answer mistake show be grasp
Knowledge and the weakness that physical efficiency is asked with knowledge solution.According to the answer situation of student, capacity superiority strong point and presence are divided into
Subject matter.
For example, (1) under the sorting of operation of number uses the relation knowledge of dividend in division, divisor, business and remainder, solve
The ability of division calculation problem；(2) method knowledge of the estimation of number is used, the ability of simple estimation application problem is solved；Etc..
Compensating module is that can be presented according to knowing for student the problem of key element, and the survey topic that this knows energy key element is extracted in compensation,
To be used as compensation exercise；Further according to the subject matter of presence, the study to student proposes specific guiding opinion, and provides exercise
Topic.
For example：Know can key element be dividend, divisor, relation of business and remainder etc. in division.
