Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.
Fig. 1 is a schematic flow chart of a method for acquiring test paper questions according to an embodiment of the present invention, by which test paper questions are acquired, not only labor costs and time costs can be reduced, but also quality of the test questions can be ensured to improve a test effect on a student.
As shown in fig. 1, the method for acquiring test paper questions in this embodiment includes the following steps:
step S1: and acquiring elements related in the analysis process of each test question in the question library and keywords related to the stem of each test question.
In order to facilitate description of the technical solution of this embodiment, elements related to the process of analyzing the test question are referred to as elements of the test question, and keywords related to the stem of the test question are referred to as keywords of the test question.
In this embodiment, the elements of the test questions include, but are not limited to, knowledge points involved in the analysis process of the test questions, and the elements of the test questions in the question bank are matched with the current learning stage of the learner, for example, for the second-level learner, the knowledge points of only the second-level course are stored in the question bank, and the knowledge points of the first-level course are not included. The test questions in the question bank are not only provided with corresponding answers, but also provided with a resolving process for the test questions, and one or more elements are involved in the resolving process. The user can mark the related elements in the process of analyzing the test questions, and the elements in the process of analyzing each test question are acquired through identifying the marks when the test questions are stored in the question bank.
The keywords of the test questions are keywords useful for solving the test questions in the stem of the test questions, and in the embodiment, the keywords in the stem of each test question can be marked in a manual marking mode, and when the test questions are stored in the question bank, the keywords of the test questions can be obtained through identification of the marks.
Step S2: and determining the difficulty level of each test question according to the number of the elements and the number of the keywords of each test question.
When the number of elements of a test question is acquired, the situation that knowledge points are repeated is not considered, for example, when ten elements are involved in the analysis process of the test question, the number of elements corresponding to the test question is ten even if the types of the plurality of elements are the same.
In this embodiment, a preset relationship model may be first adopted, the difficulty of each test question is calculated according to the number of elements and the number of keywords of each test question, and then a corresponding difficulty level is obtained according to the interval where the difficulty of each test question is located.
The more the elements of the test questions are, the larger the workload of the analysis process of the test questions is, the more the logic is complex, and the higher the difficulty level of the test questions is; the more keywords contained in the stem of the test question, the more resources can be utilized in the analysis process, and the less difficulty of the test question; conversely, if the number of keywords included in the stem of the test question is smaller, the fewer resources that can be utilized in the analysis process are, and the greater the difficulty of the test question is. Therefore, in this embodiment, the number of keywords of the number of elements of the test questions is used as a basis for determining the difficulty level of each test question, so that the accuracy of evaluating the difficulty level of the test questions can be improved.
Step S3: and acquiring element information and difficulty information of the target test paper.
In this embodiment, the element information and the difficulty information of the target test paper may be obtained according to input data of the user, where the element information of the target test paper includes content to be tested in the target test paper, and the difficulty information includes difficulty level to be reached by the target test paper.
Step S4: and determining target elements of each question type in the target test paper according to the element information of the target test paper, and determining target difficulty of each question type in the target test paper according to the difficulty information of the target test paper.
Multiple question types such as selection questions, filling questions, solving questions and the like can be arranged in the target test paper, and the test effects of different question types are different for different types of elements, so that the various elements are respectively provided with the corresponding optimal test question types. For example, if the test effect is best when a certain type of element adopts the selection questions, the best test question type of the type of element is the selection questions; if the test effect of the gap filling problem adopted by a certain element is best, the best test problem type of the element is the gap filling problem; if the test effect of solving the answer is best for a certain element, the best test question type of the element is the answer. After obtaining the element information of the target test paper, each type of element can be allocated to the corresponding question type according to the optimal test question type of each element related in the element information so as to obtain the target element of each question type.
When the target difficulty of each question type is determined according to the difficulty information of the target test paper, the correction coefficient of each question type can be set first, and then the difficulty information of the target test paper and the correction coefficient of each question type are multiplied, so that the target difficulty of each question type can be calculated.
Step S5: and selecting target test questions corresponding to the target elements and the target difficulties of the question types from the question library according to the elements and the difficulty grades of the test questions.
When the target test questions are acquired from the question bank, the superclass test questions in the question bank are firstly excluded, namely the test questions related to elements which are not in the knowledge range of students are excluded. In this embodiment, the elements may be ranked according to the learning order of the elements, and the ranks of the elements of each question in the question library may be labeled. When the target test questions are acquired from the question bank, the highest level of the elements in the element information of the target test paper can be acquired first, and the test questions related to the elements with the level higher than the highest level in the question bank are used as super-class test questions.
And then, selecting target test questions from the question bank according to the factors and the difficulty level of the test questions by taking the target factors and the target difficulty as constraint conditions, and sorting the target test questions in the question types according to a preset sequence, for example, sorting the target test questions from small to large according to the difficulty level, thereby obtaining the target test paper.
In summary, in the technical solution of this embodiment, not only the elements involved in the process of solving each test question in the question bank are determined, but also the keywords of the stem of each test question are obtained, and the difficulty level of each test question is determined according to the elements and keywords of each test question. When the target test questions of the target test paper are acquired, element information and difficulty information of the target test paper are firstly determined, then target elements and target difficulty of each question type are determined according to the element information and the difficulty information of the target test paper, and finally corresponding target test questions are selected from a question bank according to the target elements and the target difficulty. According to the technical scheme, the target test questions of the target test paper can be acquired without participation of people, so that the labor cost and the time cost can be reduced; when the target test questions of the target test paper are acquired, the element information and the difficulty information of the target test paper are considered, so that the target test paper can simultaneously meet the requirement of the target test paper on the element and the requirement of the target test paper on the difficulty, the quality of the acquired target test paper can be ensured, and the aim of improving the test effect is fulfilled.
In one embodiment of the present invention, a process of determining the difficulty level of each test question according to the number of elements and the number of keywords in step S2 is shown in fig. 2, and includes the following steps:
step S21: and acquiring the combination difficulty among the elements of each test question.
In this embodiment, the difficulty of combination between the elements may be set by the user, or the number of combinations between the elements in all the questions in the question bank may be counted to obtain the frequency of occurrence of the combination between the elements, and then the difficulty of combination between the elements is obtained according to the frequency: the less frequently a combination between elements occurs, the greater the difficulty of its combination.
Step S22: and obtaining the difficulty level of each test question according to the number of key words of each test question, the number of elements and the combination difficulty among the elements.
For example, assume that the number of elements of one of the questions is N, the number of keywords is S, and the difficulty of combination between the ith element and the (i+1) th element is A i The difficulty H of the test question is calculated by the following formula:
wherein alpha is a combination difficulty coefficient, beta is a keyword coefficient, and gamma is a correction coefficient. And then obtaining the difficulty level of each test question according to the section where the difficulty of each test question is located.
By the setting mode of the embodiment, the number of keywords and the number of elements of each test question are considered when the difficulty level of the test question is acquired, and the combination difficulty among the elements is considered, so that the accuracy of judging the difficulty level of the test question can be improved.
In one embodiment of the present invention, the element information of the target test paper acquired in step S3 includes not only the type of the element but also the weights of the elements of the various types.
Accordingly, in step S4, determining the target element of each question type in the target test paper according to the element information of the target test paper includes:
firstly, determining the total duty ratio of each element in a target test paper according to the weight of each element;
and then, obtaining the preset duty ratio of each type element in each question type according to the total duty ratio of each type element in the target test paper.
In this embodiment, the sum of the weights of the knowledge points may be calculated first, and the calculation result is taken as a total weight value, and then the ratio between the weights of the knowledge points and the total weight value is taken as the total duty ratio of the corresponding knowledge points in the target test paper.
Assuming that M types of elements are involved in element information of a target test paper, wherein the weight of the j-th element is W j The total ratio L of the elements in the target test paper j The method comprises the following steps:
in this embodiment, the optimal allocation proportion of each type of element in each question type may be obtained according to the optimal test question type corresponding to each type of element, and then the preset duty ratio of each type of element in each question type may be obtained according to the total duty ratio of each type of element in the target test paper and the corresponding optimal allocation proportion.
Let the optimal distribution ratio of the j-th element in one of the questions be Y j The preset duty ratio Z of the type element in the question type j The method comprises the following steps:
by the setting mode of the embodiment, the preset duty ratio of each element in each question type can be obtained according to the weight of each element, so that the target test questions can be selected from the question bank quickly, and the accuracy of selecting the target test questions is improved.
In one embodiment of the present invention, in the step S5, a process of selecting a target question corresponding to a target element and a target difficulty of each question type from a question bank according to the element and the difficulty level of each question is shown in fig. 3, and the process includes the following steps:
step S31: and obtaining the difficulty level distribution of each question type according to the target difficulty of each question type.
In this embodiment, the preset difficulty coefficient of each test question in each question type may be set first, and then the preset difficulty level of each test question is obtained according to the preset difficulty coefficient of each test question and the target difficulty level of the corresponding question type, so as to obtain the difficulty level distribution of each question type.
For example, assume that one of the question types has a target difficulty of X, and the question type has a plurality of questions, wherein the preset difficulty coefficient of the nth question is X n The preset difficulty of the test question is that
h j ＝x n ×X
And then according to the interval where the preset difficulty is located, the preset difficulty level of the test question can be reached.
