Abstract

The invention discloses a computer-aided testing method for intelligent teaching. The computer-aided testing method comprises the steps of setting question volume distribution of an initial test of simulation testing; performing simulation testing through the initial test of simulation testing after independent study, performing the next round of independent study again when students fail to pass the simulation testing, otherwise, performing end-of-term testing, and using an intelligent test volume distribution adjustment method in test paper of the end-of-term testing; adjusting the test volume distribution of the end-of-term test intelligently; for the end-of-term test after adjustment of test volume distribution, using a random test paper setting method; completing study if the students pass end-of-term testing, otherwise, performing independent study again. According to the method, simulation testing is performed in an intelligent test paper setting mode to perform individual guidance on learning behaviors of students every time and help students complete subject learning faster and better, and accordingly learning testing of students can be completed intelligently, and the testing effect is good.

Accompanying drawing explanation

Fig. 1 is the Computer Aided Measurement process flow diagram for intelligent tutoring that the embodiment of the present invention provides.

Fig. 2 is the process flow diagram of the embodiment 1 that the embodiment of the present invention provides.

Embodiment

In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with embodiment, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.

Below in conjunction with accompanying drawing, application principle of the present invention is explained in detail.

As shown in Figure 1, the Computer Aided Measurement for intelligent tutoring of the embodiment of the present invention comprises the following steps:

S101: the volume distribution that the initial examination question of simulation test is set;

S102: after autonomous learning, uses the initial examination question of simulation test to carry out simulation test, when student's simulation test does not pass through, then re-starts the autonomous learning of next round, otherwise carry out end of term test;

S103: the intelligent volume distribution adjustment of end of term test examination question;

S104: for the end of term test examination question after volume distribution adjustment, adopt the random creating test papers method of paper;

S105: tested by the end of term, then complete study, otherwise autonomous learning again.

Below in conjunction with specific embodiment, application principle of the present invention is further described.

Step one: the initial volume distribution of simulation test calculates;

The volume distribution of the initial examination question of simulation test is set.In certain section's object end of term test volume, a typical model of the volume distribution of each knowledge point is as shown in table 1.

Table 1

Step 2: after autonomous learning, the initial examination question of simulation test is used to carry out simulation test, when student's simulation test does not pass through, then re-start the autonomous learning of next round, otherwise carry out end of term test, in the paper of end of term test, adopt the method for intelligent volume distribution adjustment, target reaches following effect:

The score value that in last test, certain knowledge point obtains is higher, and this this knowledge point proportion of test volume will reduce, and means that repeated test amount will be reduced in the knowledge point that student has grasped.

The score value that in last test, certain knowledge point obtains is lower, and this this knowledge point proportion of test volume will increase, and means that the knowledge point that student does not grasp will increase test volume, can concentrate on thin spot and carry out by instruction of papil like this in follow-up study.

In order to consider characteristic of oblivion, even if student certain knowledge point in last test obtains full marks, in this test volume, ratio can not reduce to 0, and agreement comprises one exercise question.Always there is test machine meeting each knowledge point of such guarantee, avoid student forget cause this knowledge point in the end to be tested in can not pass through.

Step 3: the intelligent volume distribution adjustment of end of term test examination question.

1. according to student for knowledge point K _icurrent score values S _iwith initial volume distribution A _icalculate the reference volume distribution B of this knowledge point _i:

$B_i=\frac{\underset{i=1}{\overset{n}{\Σ}}{S}_i}{100}{A}_i;$

2. according to S _iand B _idifference determine the volume distribution adjustment amount C of this knowledge point _i:

$C_i=(B_i-S_i)\frac{100}{\underset{i=1}{\overset{n}{\Σ}}{S}_i};$

3. according to A _iand C _idifference determine this knowledge point renewal volume distribution D _i:

D _i＝A _i+C _i

4. make Sum=0, the final volume distribution of the employing for this knowledge point ND _ibe then:

A) for all D _i=0, ND is set _i=min{ knowledge point K _iexam pool in the minimum score value of all exercise questions; Sum=Sum+ND _i.

B) for all D _i>0, ND _i=D _i-(D _i/ 100) * Sum.

Such as student A is after certain simulation test, and the volume distribution adjustment of this raw follow-up simulation test is as shown in table 2 below:

Table 2

Following table 3 gives student A certain knowledge point in last test and obtains the disposition after full marks:

Table 3

Step 4: for the end of term test examination question after volume distribution adjustment, adopt the random creating test papers method of paper.As related to knowledge point K in exam pool _ithe score value of each topic as shown in table 4:

Table 4

The probability Q that exercise question Ti is selected _ifor:

$Q_i=\frac{P_i}{\underset{i=1}{\overset{n}{\Σ}}{P}_i};$

Knowledge point K _igroup lick journey and be:

1) alternative exercise question S set=(1,2,3.。。, 14); K _ivolume be distributed as A _i=10; The order set Z that selected a topic is for empty.

2) in the middle of S, get a number i at random, consider exercise question T _i.

A) as residue score value P-P _iwhen=0, Z=ZU{T _i, successfully exit.

B) as residue score value P-P _iwhen being greater than 0, and the score value that there is exercise question is less than P-P _itime, this selects a topic unsuccessfully, turns 2 and selects next to inscribe; Otherwise turn 1 and restart group volume.

Knowledge point K _i(A _i=10) group volume process instance is as shown in table 5:

Table 5

Step 5: tested by the end of term, then complete study, otherwise autonomous learning again.

The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
