Description

Automatic sorting system for full subject problems

Technical Field

The invention relates to a full-subject problem difficulty automatic sequencing system, and belongs to the technical field of education evaluation.

Background

In the study practice, the academic examination questions need a scientific method to determine the difficulty, and the 'difficulty' of the questions presented in the reality is estimated in a column which is empty. At present, the difficulty of the subject, and the proposition in various places, is determined by the sense. This is a problem, and the difficulty difference estimated by different people is very large. The difficulty is an important index for investigating whether a test question can be scaled, and the traditional method is obtained by estimation or is represented by the score loss rate after testing. It is obvious that the difficulty of restating the subject is not significant.

The subject difficulty is an important factor for causing academic burden to students. Whether the work is done outside the class or various examination questions are only large in quantity, the psychological burden of students cannot be too heavy and difficult to solve, and the psychological burden of the students is inevitably heavy. Currently, when teachers of various subjects in middle and primary schools leave homework for students, the difficulty of questions is determined by feeling, and the difficulty of proposing questions in various examinations is also determined by feeling. The difficulty of the subjects of homework or examination is not uniformly determined, so that the students have uneven homework, and the students have subjects difficult to answer every day to bother the students. In addition, the difficulty of the examination is uncertain, the difficulty is increased at will, and no upper limit exists, so that the burden of the academic industry is more and more severe for teachers, parents and students to cope with the examination with the difficulty increased at will.

Is the person who is proposing the topic not want to determine the difficulty of the topic in a suitable range? Not. Because there is no original metering method for scientific calculation difficulty. Since the difficulty is estimated by feeling, the reliability of the ruler of the test question is greatly discounted, and the score obtained by the test of the test question is obviously discounted. Education evaluation needs testing, the testing needs uniform scale, and the important factor of uniform scale, namely 'subject difficulty', needs a scientific measuring method.

Disclosure of Invention

In order to solve the problems in the prior art, the system for automatically calculating the difficulty and automatically ordering the problem difficulty is provided.

The technical scheme adopted by the invention is as follows: a full subject problem difficulty automatic ordering system comprises a parameter marking module, a problem classification module, an intelligent index calculation module and an intelligent index ordering module;

a parameter marking module: the method comprises the steps that a question provider sends questions to a system according to requirements, wherein the questions of the question provider contain answers and analysis data, the questions need to note investigated knowledge points, all knowledge item numbers are used in the problem solving, repeated items are also accumulated, m is recorded as all knowledge item numbers including the repeated items, and p is the repeatedly used knowledge item number; counting the number of effective data in the questions, and recording r as the number of effective data in the application questions; counting the sentence number of the reading material by taking the sentence number as a node for reading the comprehension title, and recording d as the sentence number of the reading material;

a topic classification module: marking m and d in the questions, and classifying the questions into reading material question areas; marking m and r in the questions, and classifying the questions to an application question area; only marking m or marking m and p in the questions, and classifying the questions to a basic knowledge question area; the intelligent index calculation module: respectively calculating intelligent indexes of corresponding questions according to the question classification areas in the module;

the intelligent index calculation formula adopted by the subjects in the reading material subject area is as follows:

wherein: m is the number of all knowledge items including repeated items, d is the number of sentences of the reading data, and d is more than or equal to 3; carrying and rounding an intelligent exponent calculation result;

the intelligent index calculation formula adopted by the questions in the application question area is as follows:

wherein: m is the number of all knowledge items including repeated items, p is the number of the repeatedly used knowledge items, and r is the number of effective data in the application questions; m is more than or equal to 2, p is more than or equal to 1, and r is more than or equal to 2;

the intelligent index calculation formula adopted by the questions in the basic knowledge question area is as follows:

when the topic contains the number of repeatedly used knowledge items, the intelligent index calculation formula is as follows:

n＝3m-2(p-1)

wherein: m is the number of all knowledge items including repeated items, p is the number of the repeatedly used knowledge items, m is more than or equal to 2, and p is more than or equal to 1;

when the topic does not contain the number of repeatedly used knowledge items, the intelligent index calculation formula is as follows:

wherein: m is the number of all knowledge items including the repeated items;

the intelligent index sorting module: marking the intelligent index obtained by calculation on the corresponding topic, and then classifying the topic into the corresponding subject library module according to the subject. The same type of questions in the question bank are sorted from small to large according to the intelligent index, and the difficulty is selected according to the intelligent index n value during application.

When students do questions, the intelligence activities of brains are realized, the principle of brain science is applied, the process of doing the questions by the students is decomposed into small intelligent activity links, the more the number of intelligent nodes for each small link called an intelligent node to answer one question by the students is, the more the intelligence labor is, and the difficulty is high. Therefore, a method for measuring the difficulty of answering the test questions by using the 'intelligent section' is found.

No matter what disciplines, there are several knowledge points that a propositor can definitely investigate when proposing a question, and what is the specific, so the number m of knowledge items needed for calculating an intelligent index is determined;

if the problem is a mathematical, physical and chemical application problem, not only the examined knowledge point is determined, but also the number of valuable data for solving the problem contained in the question is determined when the question is presented to the tested person, namely m is determined and r is also determined;

for the subject with the reading material, the examined knowledge point is determined, and the number of sentences contained in the reading material is also determined, namely m and d are determined.

The invention has the beneficial effects that: the system comprises a parameter marking module, a topic classification module, an intelligent index calculation module and an intelligent index sorting module. In the application process of the system, no matter classroom practice, post-lesson work and unit small test are carried out, a teacher can have a plurality of subjects selected by the teacher, the teacher needs to carry out hierarchical teaching in the teaching, the levels to be divided are self-defined, the subjects can be automatically separated according to the needs of the teacher, and the system is very convenient to use. Teachers can select questions according to the intelligent index values of the questions, the selected questions are suitable for students, and learning results of the students can be better checked. All parameters in the intelligent index calculation formula are necessary for the subject, and objective fairness of the calculation result is determined.

Wherein: m is 8, p is 1, r is 4; r is marked in the question and belongs to the application question area, so an intelligent index calculation formula adopted by the question in the application question area is adopted:

and marking the intelligent index n as 27 on the question, and classifying the question into a corresponding question bank module.

Example 5 Intelligent index calculation for topics in reading material topic area

The Chinese character Qinqi Yashi is a Qing-Qu Yashi which is old and a senior high school Chinese teacher with Chinese characters in love, Chinese character culture promotion and life instinct pursuing. Although this new school is called "foreign language school", the first chinese class, old and heavy, tells students: "to become a translator, the person who gives a foreign exchange should first learn not the foreign language but the Chinese language. "

Secondly, the Chinese characters in the cang Jie are felt to be ancient, vicious, luxurious and fresh after going to the platform every time, and the Chinese characters are wonderful and fall off like light rain and dust and rush to the heart. The Chinese characters in the square blocks have feelings, have the advantages of having a take-off and take-over effect, being capable of enjoying the liver and gallbladder, being capable of complaining about the complains of the people and being capable of dance of the dance. Chinese characters and dancing are both nature and life.

And thirdly, in the first lesson, when the old is in the magical strength of the growth of all things in spring, the passion is full. He squats down, curls the whole body behind the platform like a seed and a bird egg, then erects the index finger, and slowly rotates upwards, and an upward force pushes the whole body to spiral and rise. The whole class of sparrow is silent, and the person elongates the neck and looks old and clumsy "dance". The old feels that the light flows backwards as if the old were back to the age of the first tooth and the first beard.

And fourthly, finishing the operation in the classroom, hearing the students to play a new generation of medicated leaven fox call in the old before going to another class for class. Norwegian medicated leaven called Fox simulates the singing of puppies, bullfrogs and elephants ducks and is similar to the singing of children, but before the simple and natural sound, how much the singing with exhausted hoarseness is done is corrected and kneaded. Old in forbiddance, it is somewhat uneven, "aq" think: the Bing Hanzi is actually a work derived from nature and humanity, and is the most complicated and great one of human beings, when they are popular?

No lessons in afternoon, and the old will fall in the air slightly. The general perception of the sky now becomes lower and lower compared to when young. The sky continues to go around, but as if the "point" of the "hollow" word were shrinking, the "work" below expands a day. The sky is crowded with turbid matter like a traditional Chinese painting without leaving white, and the bird releases the song throat chirp only in the KTV. The Chinese characters created according to the signs of the landform astronomical phenomena and the insects and the fishes of the birds and the animals are intentionally and unintentionally 'opened and counterfeited' in the advertising words of the signboards and the full screens which lose the association in the nature. The traders inspired deeply to misinterpret Chinese characters, the tune of the spice "innovated" Chinese characters in an attempt to attract the eyeball.The moustache is pulled out a little bit in the storehouse, the coat is peeled off, only the skeleton is left, and the bone is petrified and fixed in the shrine of the temple The above.

Sixthly, the old people who take the long and illegal brush pen writes the auxiliary couplet: sea is the dragon world and heaven is the crane hometown. He suddenly understood why ancient Hui ink was "light in the pick, soft in the smell, and clear in the grind", which must be because Hui ink was made from yellow mountain pine smoke. The nature object is visualized into a point horizontal, vertical, left falling and right falling, namely the Chinese character; jinsong comes out, and can be a millennium Shengbao; while essence and spirit are lifelong.

Seventhly, in the night, the tree seams are like hooks under the tall and sparse phoenix wood, and the shape of the tree seams is the same as that of the Chinese character 'yue' in the seal character. When going home, turning off the light for sleeping, and when the user sleeps without trance, the user feels scenery outside the window by closing the eyes, and the scenery looks like dancing as if all things are dancing. The Yinxu tortoise shell, bronze inscription, Dunhuang scroll and Mothur stone carving all Chinese characters jump, and the Yanjin willow bone and the atrophasin are restored to horse dance and hip dance at a moment. Bird flying from the branch and falling into the case; the branches tremble like strings; the flying birds and the loess dust in the sky race freely, and the banker can take the six qi's differentiation from the ' right of the heaven and the ground ' to enjoy the leisure flying crow army. When the person is tired, the bird leans against the tree to rest, and when the bird is tired, the feather is combed on the crotch. Grand building of the Alang palace has the relief of earth, the horn of a hook, and fine and smooth Daorhizu Daizhou of the Langting Ji, and the reflection band is hooked; the Chinese characters come and go by the Chinese characters of cang, Quyuan, Wang Xi, Du Mu, Qin brick Han Wa, Lijia Zhen Zi Cao and the famous students strive to express and deduce the respective thought and seal. Tea Ma ancient road, crisscross Qianmo, cang Jie Chinese characters as if the moon is empty. Even if the E-mail replaces the post messenger, the Chinese characters are still static and intentional, and the Chinese characters are dancing when the E-mail is moved. Old than deeply sucking a breath, a cool and refreshing sensation is transmitted to the sole of the foot from the beginning. In the dream, when Weicheng is fresh and dusty towards rain wet, the Wenyang people see that the crown of the ten-thousand nations strives for customs and that hundreds of students click on customs at the ancient road before Yanguan. The city wall with side plugs is full of Chinese character genuine 'xiu'. The pen with the character of heaven is healthy qi, the pen with the color of youthful paniculate swallowwort is powerful, the pen with the hard bone of the faithful … … of the elytrigia lying on the back and in a thousand-posture is in a different state, but the pen with the middle front. Old dream feels a full body with fever and tries to stretch tendons and pull bones, so it seems that the body is still growing. (selected from the "sunshine journal", with deletion and modification)
