推广和延伸 (1)

创建一个测评函数，返回一个 AssessmentResultObject，其中的分数为答案的函数：

	isItGreen]

选项 (2)

EpilogFunction (1)

用 QuestionObject 中的 EpilogFunction 将结果记录到文件中：

QuestionObject[QuestionInterface["MultipleChoice", <|"Prompt" -> "What is 4^3?"|>], 
	AssessmentFunction[{16, -64, 64 -> 1}], EpilogFunction -> (PutAppend[#Assessment, "assessmentresults"]&)]

查看记录的评估结果：

Wolfram Language code: ReadList["assessmentresults"]

清除记录：

Wolfram Language code: DeleteFile["assessmentresults"]

ImageSize (1)

用 ImageSize 设置 QuestionObject 的宽度：

Wolfram Language code:

QuestionObject[QuestionInterface["TrueFalse", <|"Prompt" -> "Is it accurate to say that a whale belongs to the class of animals known as mammals? True or false?"|>], TrueQ, ImageSize -> 500]

设置高度：

Wolfram Language code:

QuestionObject[QuestionInterface["TrueFalse", <|"Prompt" -> "Is it accurate to say that a whale belongs to the class of animals known as mammals? True or false?"|>], TrueQ, ImageSize -> {300, 300}]

应用 (1)

定义一个函数，生成问题的随机版本：

Wolfram Language code:

factorQuestion[] := With[{n = RandomInteger[{10, 100}]}, QuestionObject["What are the prime factors of " <> ToString[n, TraditionalForm], 
	AssessmentFunction[RandomSample[{{2, 3, 5} -> 0, (First /@ FactorInteger[n]) -> 1, 
	Prime /@ Sort[RandomInteger[{2, 10}, 3]] -> 0}]]]
	]

生成问题的两个版本：

Wolfram Language code: factorQuestion[]

创建一个等效的 QuestionGenerator：

Wolfram Language code:

factorGenerator = QuestionGenerator[
	{"n" :> RandomInteger[{10, 100}]}, 
	QuestionObject["What are the prime factors of " <> ToString[#n, TraditionalForm], 
	AssessmentFunction[RandomSample[{{2, 3, 5} -> 0, (First /@ FactorInteger[#n]) -> 1, 
	Prime /@ Sort[RandomInteger[{2, 10}, 3]] -> 0}]]]&
	]

Wolfram Language code: factorGenerator[2]

属性和关系 (2)

当无法从评估中推断出界面类型时，将使用输入栏：

Wolfram Language code: QuestionObject["Approximately how many asteroids are in the asteroid belt?", Between[{1100000, 2000000}]]

未定义评估函数时，将省略提交按钮：

Wolfram Language code:

QuestionObject[ QuestionInterface["MultipleChoiceGrid", <|"Prompt" -> "Rate these foods:", "Choices" -> {"Ice cream", "Pizza", "Watermelon", "Popcorn"}, "Categories" -> {1, 2, 3, 4, 5}|>]]

Top
