The following code works as expected! 

It is important to use a frame-environment and the "fragile"-option.

\begin{frame}[fragile]
...
\end{frame}

##################################

\documentclass{beamer}


\usepackage[latin1]{inputenc}
\usepackage[T1]{fontenc}

\usepackage{ngerman}

\begin{document}

\begin{frame}[fragile]
  \frametitle{test}
test
<<>>=
 1+1
@ 
\end{frame}
\end{document}
