班级成绩单根据问题和解决方案自动评分

Question

我使用 exsheets 课程进行练习和考试，一切都非常可配置，但我对按问题处理积分有一些问题......

\documentclass{scrartcl}
\usepackage{exsheets}

\begin{document}

\SetupExSheets[question]{print=true}
\SetupExSheets[solution]{print=true}
% Note in my version of exam : questions and solutions are not display in the same file => 2 pdf exam witch questions and corrections

% The solution with grading table is also not automatic...

\begin{question}% I want the total points computed automatically ?

  \begin{enumerate}
    \item \addpoints{1}
    Question 1
    \item \addpoints{2}
    Question 2
  \end{enumerate}
  \currentpointssum*
\end{question}

\begin{solution}% I want the total points computed automatically ?
  \begin{enumerate}
    \item \points{1}
    Question 1
    \item \points{2}
    Question 2
  \end{enumerate}
\end{solution}

\begin{question}

  \begin{enumerate}
    \item \addpoints{3}
    Question II.1
    \item \addpoints{4}
    Quesion II.2
  \end{enumerate}
  \currentpointssum*
\end{question}

\begin{solution}
  \begin{enumerate}
    \item \points{3}
    Question II.1
    \item \points{4}
    Quesion II.2
  \end{enumerate}
  \currentpointssum*
\end{solution}

\end{document}

一个解决方案是您手动输入问题总数，但我确定有一个可以自动计算的解决方案？

提前谢谢你。

问候。

Answer 1

使用最新版本的 ，这实际上相当容易exsheets。想法是这样的：定义一个新的容器（l3 中的盒子或棺材）来保存问题的要点：

\DeclareExSheetsHeadingContainer{autopoints}{%
  \points{\GetQuestionProperty{points}{\CurrentQuestionID}}%
}

\GetQuestionProperty这里需要两次编译才能获取正确的值。

现在使用新容器（我称之为autopoints）代替points正在使用的标题实例中的预定义容器。对于下面的示例，我将标题的定义复制block为myblock并替换points为autopoints：

\DeclareInstance{exsheets-heading}{myblock}{default}{
  join   = { title[r,B]number[l,B](1ex,0pt) } ,
  attach = {
     main[l,vc]title[l,vc](0pt,0pt) ;
     main[r,vc]autopoints[l,vc](\marginparsep,0pt)
   }
}

现在您要做的就是使用新的标题：

\SetupExSheets{headings = myblock}

以下是完整的示例：

\documentclass{scrartcl}
\usepackage{exsheets}[2015/11/18]% need v0.20

% define a new heading container which fetches the points of a question:
\DeclareExSheetsHeadingContainer{autopoints}{%
  \points{\GetQuestionProperty{points}{\CurrentQuestionID}}%
}

% define a variant of the `block' heading which uses the new container instead
% of the usual one for points:
\DeclareInstance{exsheets-heading}{myblock}{default}{
  join   = { title[r,B]number[l,B](1ex,0pt) } ,
  attach = {
     main[l,vc]title[l,vc](0pt,0pt) ;
     main[r,vc]autopoints[l,vc](\marginparsep,0pt)
   }
}

% setup exsheets to use the new heading:
\SetupExSheets{
  headings = myblock ,
  question/print=true ,
  solution/print=true
}

\begin{document}

\begin{question}
  \begin{enumerate}
    \item \addpoints{1}
    Question 1
    \item \addpoints{2}
    Question 2
  \end{enumerate}
\end{question}

\begin{question}
  \begin{enumerate}
    \item \addpoints{3}
    Question II.1
    \item \addpoints{4}
    Quesion II.2
  \end{enumerate}
\end{question}

\end{document}
