在本示例实施例中，首先提供了一种自动生成数学选择题答案选项的方法，可以应用于计算机等电子设备；参考图1中所示，该自动生成数学选择题答案选项的方法可以包括以下步骤：In the present exemplary embodiment, a method for automatically generating a mathematical multiple-choice answer option is first provided, which can be applied to an electronic device such as a computer; as shown in FIG. 1, the method for automatically generating a mathematical multiple-choice answer option can include the following step:

步骤S110.获取数学选择题的题干信息，根据所述题干信息进行分步计算，并记录分步计算过程；Step S110. Acquire the stem information of the mathematics multiple-choice question, perform step-by-step calculation according to the question dry information, and record the step-by-step calculation process;

Perform a mutation operation on the step-by-step calculation process, and obtain a second result according to the mutation operation result, and use the second result as an error option of the mathematical multiple choice question.

根据本示例实施例中的自动生成数学选择题答案选项的方法，一方面，由于自动生成数学选择题答案选项，节省了人员成本，可以缩短出题时间；另一方面，建立突变运算模型，通过对答题信息的统计再分析，可以使生成的错误选项更贴合用户的易错点，提升了教学效果。According to the method for automatically generating a mathematics multiple-choice answer option in the exemplary embodiment, on the one hand, since the mathematics multiple-choice answer option is automatically generated, the personnel cost is saved, and the time of the question can be shortened; on the other hand, the mutation operation model is established, The statistical reanalysis of the answer information can make the generated error options more suitable for the user's error-prone points and improve the teaching effect.

下面，将对本示例实施例中的自动生成数学选择题答案选项的方法进行进一步的说明。Next, the method of automatically generating the mathematics answer answer option in the present exemplary embodiment will be further described.

在步骤S110中，可以获取数学选择题的题干信息，根据所述题干信息进行分步计算，并记录分步计算过程；In step S110, the stem information of the mathematics multiple-choice question may be acquired, the step-by-step calculation is performed according to the question dry information, and the step-by-step calculation process is recorded;

本示例实施方式中，在获取到数学选择题的题干信息后，若所述数学选择题的题干信息为有实质内容的计算题，则根据所述题干信息进行分步计算。如：In the example embodiment, after the stem information of the mathematics topic is obtained, if the stem information of the mathematics question is a calculation question having a substantial content, the stepwise calculation is performed according to the stem information. Such as:

“选择题1：函数

的根为()”， "Multiple Choice 1: Function

The root is ()",

“步骤一：移相，x ²-3x-4＝0； "Step 1: Phase shift, x ² -3x-4 = 0;

步骤二：配方，(x-4)(x+1)＝0；Step 2: Formula, (x-4) (x+1) = 0;

步骤三：求得方程的根为：x＝4或x＝-1。”Step 3: Find the root of the equation as: x=4 or x=-1. ”

在进行分步计算过程中，记录上述分步计算过程。In the step-by-step calculation process, the above step-by-step calculation process is recorded.

在步骤S120中，可以根据所述分步计算过程得出第一结果，并将所述第一结果作为所述数学选择题的正确选项；In step S120, a first result may be obtained according to the step-by-step calculation process, and the first result is used as a correct option of the mathematical multiple choice question;

本示例实施方式中，根据所述分步计算过程得出第一结果，以上述步骤S110中示例为例，分析所述选择题的分步计算过程得出第一结果为:“方程的根为：x＝4或x＝-1”，将所述第一结果作为所述数学选择题的正确选项：In the example embodiment, the first result is obtained according to the step-by-step calculation process. Taking the example in step S110 as an example, analyzing the step-by-step calculation process of the multiple-choice question results in the first result: “The root of the equation is :x=4 or x=-1", using the first result as the correct option for the mathematical multiple choice question:

“A.x＝4或x＝-1”或，"A.x=4 or x=-1" or,

“A.x＝4，B.x＝-1”"A.x=4, B.x=-1"

由上述示例可以看出，所述第一结果可以生成一个正确选项，也可以生成多个正确选项。As can be seen from the above examples, the first result can generate a correct option or multiple correct options.

在步骤S130中，可以对所述分步计算过程进行突变运算，根据所述突变运算结果得出第二结果，并将所述第二结果作为所述数学选择题的错误选项。In step S130, a mutation operation may be performed on the step-by-step calculation process, a second result is obtained according to the mutation operation result, and the second result is used as an error option of the mathematical multiple choice question.

本示例实施方式中，对所述分步计算过程进行突变运算，可以是对分步计算过程中的所有计算因子都进行突变运算，也可以是对分步计算过程中的部分计算因子都进行突变运算。所述分步计算过程中的计算因子包括但不限于数学符号、数学分式、运算顺序等。In the exemplary embodiment, the step-by-step calculation process performs a mutation operation, which may be a mutation operation on all calculation factors in the step-by-step calculation process, or may be a mutation in some calculation factors in the step-by-step calculation process. Operation. The calculation factors in the step-by-step calculation process include, but are not limited to, mathematical symbols, mathematical fractions, arithmetic orders, and the like.

仍以上述步骤S110中示例为例，如在突变运算模型中对步骤一移相时-3x项的数学符号变化的突变，则移相后方程为：x ²+3x-4＝0。相应配方及最后所求得方程的根也不同，因此突变后运算结果得出的第二结果：“方程的根为：x＝-4或x＝1”，可以将所述第二结果作为所述数学题的错误选项：“C.x＝-4，D.x＝1”。 Still taking the example in the above step S110 as an example, if the mutation of the mathematical symbol change of the -3x term when phase 1 is shifted in the mutation operation model, the equation after the phase shift is: x ² + 3x-4 = 0. The corresponding formula and the root of the equation obtained last are also different, so the second result of the operation result after the mutation: "the root of the equation is: x = -4 or x = 1", the second result can be used as the The wrong option for the math problem: "Cx=-4, Dx=1".

在日常教学中，移相不变号也是学生常发生的一个错误。如图2所示为上述步骤S110中示例自动生成的完整的一个数学选择题。In daily teaching, the phase shifting constant is also a common mistake for students. FIG. 2 shows a complete mathematical alternative question automatically generated by the example in the above step S110.

本示例实施方式中，所述分步计算过程中的计算因子包括数学符号、数学分式、运算顺序，对所述分步计算过程进行突变运算，还可以包括以下至少一种方式：In this example embodiment, the calculation factor in the step-by-step calculation process includes a mathematical symbol, a mathematical score, an operation sequence, and a mutation operation on the step-by-step calculation process, and may further include at least one of the following methods:

在分步计算过程中的计算因子使用以上至少一个方式变化后，生成第二结果，并将第二结果作为所述数学选择题的错误选项。举例而言：After the calculation factor in the step-by-step calculation is changed using at least one of the above methods, a second result is generated, and the second result is used as an error option of the mathematical multiple choice question. For example:

选择题2的题干为：“选择题2：在函数

中，自变量x的取值范围为()”，对其分步计算： The question of Choice 2 is: "Multiple Choice 2: In the function

In the middle, the argument x has a value range of ()", which is calculated step by step:

“步骤一：x的范围不等式，2-(x-1) ²≥0 "Step 1: The range of x is inequal, 2-(x-1) ² ≥ 0

步骤二：移相，(x-1) ²≤2 Step 2: Phase shift, (x-1) ² ≤ 2

步骤三：变形

Step 3: Deformation

步骤四：求解，

Step 4: Solve,

由上述示例求得第一结果并生成正确答案为：The first result is obtained from the above example and the correct answer is:

“A.

"A.

为生成错误选项，需在突变运算模型中对上述分步计算过程进行突变运算，可以对“步骤二：移相，(x-1) ²≤2”中的数学符号进行反向变化，将括号内1的系数符号变负为正，由此变为：“(x-1) ²≥2”，则此突变计算第二结果并生成错误选项为：“B.

或

也可以对“步骤三：变形

的数学分式进行计算频次变化，对2未进行开方运算，由此变为“-2≤x-1≤2”：则此突变计算第二结果并生成错误选项为：“C.-1≤x≤3”；还可以对“步骤二：移相，(x-1) ²≤2”的运算顺序进行计算顺序变化，只进行了正序开方运算，由此变为：

则此突变计算第二结果并生成错误选项为：

如图2中所示为上述示例中自动生成的完整的一个数学选择题。 In order to generate the error option, the above-mentioned step-by-step calculation process needs to be abruptly operated in the mutation operation model, and the mathematical symbols in "Step 2: Phase shift, (x-1) ² ≤ 2" can be reversely changed, and the parentheses are The coefficient symbol of the inner 1 becomes negative and becomes: "(x-1) ² ≥ 2", then the mutation calculates the second result and generates the error option: "B.

or

Can also be used for "Step 3: Deformation

The mathematical fraction is used to calculate the frequency change, and no square root operation is performed for 2, thereby becoming "-2 ≤ x-1 ≤ 2": then the mutation calculates the second result and generates the error option: "C.-1 ≤ x ≤ 3"; it is also possible to change the order of operations of "Step 2: Phase shift, (x-1) ² ≤ 2", and only the positive-order square root operation is performed, thereby becoming:

Then the mutation calculates the second result and generates the error option as:

A complete mathematical alternative automatically generated in the above example is shown in FIG.

本示例实施方式中，对所述分步计算过程进行突变运算，还可以包括：对所述分步计算过程中的一步或多步计算进行突变运算。In this example embodiment, performing a mutation operation on the step-by-step calculation process may further include: performing a mutation operation on the one-step or multi-step calculation in the step-by-step calculation process.

由于所述自动生成数学选择题答案选项方法的本质是对学生答题过程中易错点进行模拟，而学生往往在做一道题的时候，容易犯多个错误，所以本方法在对所述分步计算过程进行突变运算时，也不能仅仅只对分步计算过程中某个步骤进行突变运算，也可以是对分步计算过程中多个步骤进行突变运算，这样才能更加贴近学生的答题实际，提升教学效果。Since the essence of the automatic generation of the mathematics multiple-choice answer option method is to simulate the error-prone points in the student answering process, and the students often make multiple mistakes when doing a problem, the method is step-by-step. When the calculation process performs a mutation operation, it is not only possible to perform a mutation operation on a certain step in the step-by-step calculation process, or it may be a mutation operation on multiple steps in the step-by-step calculation process, so as to be closer to the student's actual answer and improve. Teaching effect.

本示例实施方式中，所述方法还可以包括：判断所述第一结果与所述第二结果是否一致；若所述第一结果与所述第二结果一致，则按照预设突变运算规则重新对所述分步计算过程进行突变运算，直至得到与所述第一结果不一致的第二结果。In this example, the method may further include: determining whether the first result is consistent with the second result; if the first result is consistent with the second result, re-setting according to a preset mutation operation rule A mutation operation is performed on the step-by-step calculation process until a second result that is inconsistent with the first result is obtained.

由于对所述分步计算过程的各个因子都可以进行多次突变运算，也可以对多个步骤进行突变运算，所以难免出现突变运算后的第二结果恰巧与第一结果一致的情况，所以在生成第二结果后，要对所述第一结果与第二结果判断是否一致，若恰巧一致，为了生成与所述第一结果不同的第二结果，则需重新对所述分步计算过程进行突变运算，直至得到与所述第一结果不一致的第二结果。Since the various factors of the step-by-step calculation process can be subjected to multiple mutation operations, and the mutation operations can be performed on multiple steps, it is inevitable that the second result after the mutation operation coincides with the first result, so After the second result is generated, it is determined whether the first result and the second result are consistent. If it happens to be consistent, in order to generate a second result different from the first result, the step-by-step calculation process needs to be performed again. The mutation operation is performed until a second result that is inconsistent with the first result is obtained.

本示例实施方式中，所述方法还可以包括：获取答案选项设置信息，所述答案选项设置信息包括单项选择设置以及多项选择设置；若根据所述答案选项设置信息确定当前选择题为多项选择题，则根据预设分步计算规则多次对所述题干信息进行分步计算；生成具有一个或多个正确选项的第一结果。In this example embodiment, the method may further include: obtaining answer option setting information, where the answer option setting information includes a single item selection setting and a multi-selection setting; and determining, according to the answer option setting information, that the current multiple-choice question is multiple In the multiple-choice question, the question dry information is stepwise calculated multiple times according to a preset step-by-step calculation rule; a first result having one or more correct options is generated.
