When teaching student groups at KIT, I found it very useful to summarize a session’s main points with a little quiz. To simplify the creation of those quiz slides I wrote a LaTeX environment capable of generating lists of questions (and answers) animated with LaTeX beamer.

Example application

Simple demonstration
% \documentclass{beamer}

\include{questionize}

% ... \begin{document} ...

\begin{frame}{Questionize Example}

% 0 -> animation index to start with
\begin{questionize}[0]
  \question{What is $5*5$?}{$5 * 5 = 25$}
  \ctrue{Is this true?}
  \cfalse{Is this false?}
  \ltrue{Is this true?}
  \lfalse{Is this false?}
\end{questionize}

\end{frame}

% ... \end{document} ...
questionize.tex 
\definecolor{darkgreen}{rgb}{0.,0.6,0.}

\newcounter{questionizeIndex}

\newenvironment{questionize}[1][0]{%
    \setbeamercovered{invisible}%
    \setcounter{questionizeIndex}{#1}%
    \begin{itemize}%
}{ %
    \end{itemize}%
}

\newcommand{\question}[2]{%
    % #1: question
    % #2: answer (replaces question)
    \stepcounter{questionizeIndex}%
    \item<\value{questionizeIndex}->%
    \only<\value{questionizeIndex}>{#1}%
    \stepcounter{questionizeIndex}%
    \only<\value{questionizeIndex}->{#2}%
}

\newcommand{\lquestion}[4]{%
    % #1: question label
    % #2: question
    % #3: answer label
    % #4: answer (replaces question)
    \stepcounter{questionizeIndex}%
    \item[\only<\value{questionizeIndex}->{\alt<\value{questionizeIndex}>{#1}{#3}}]<\value{questionizeIndex}->%
    \only<\value{questionizeIndex}>{#2}%
    \stepcounter{questionizeIndex}%
    \only<\value{questionizeIndex}->{#4}%
}

\newcommand{\cquestion}[2]{\question{#2}{\color{#1}{#2}}}

\newcommand{\ctrue}[1]{\cquestion{darkgreen}{#1}}
\newcommand{\cfalse}[1]{\cquestion{red}{#1}}

\newcommand{\ltrue}[1]{\lquestion{\textbf{?}}{#1}{$\checkmark$}{#1}}
\newcommand{\lfalse}[1]{\lquestion{\textbf{?}}{#1}{$\times$}{#1}}
