fixed x_module.py to only load *.yaml files as templates TODO: Note that bad templates cause the CMS not to load; it should throw exceptions instead of dying.

% Nearly any kind of edX problem can be authored using Latex as
|
|
% the source language. Write latex as usual, including equations. The
|
|
% key new feature is the \edXabox{} macro, which specifies an "Answer
|
|
% Box" that queries students for a response, and specifies what the
|
|
% epxected (correct) answer is.

\subsection{Example "option" problem}
|
|
|
|
Where is the earth?
|
|
|
|
\edXabox{options='up','down' expect='down'}
|
|
|
|
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
|
|
\subsection{Example "symbolic" problem}
|
|
|
|
What is Einstein's equation for the energy equivalent of a mass $m$?
|
|
|
|
\edXabox{type='symbolic' size='90' expect='m*c^2' }
|
|
|
|
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
|
|
\subsection{Example "numerical" problem}
|
|
|
|
Estimate the energy savings (in J/y) if all the people
|
|
($3\times 10^8$) in the U.~S. switched from U.~S. code to low flow
|
|
shower heads.
|
|
|
|
\edXinline{Energy saved = }\edXabox{expect="0.52" type="numerical" tolerance='0.02' inline='1' } %
|
|
\edXinline{~EJ/year}
|
|
|
|
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
|
|
\subsection{Example "multiple choice" problem}
|
|
|
|
What color is a bannana?
|
|
|
|
\edXabox{ type="multichoice" expect="Yellow" options="Red","Green","Yellow","Blue" }
|
|
|
|
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
|
|
\subsection{Example "string response" problem}
|
|
|
|
In what U.S. state is Detroit located?
|
|
|
|
\edXabox{ type="string" expect="Michigan" options="ci" }
|
|
|
|
An explanation of the answer can be provided by using the edXsolution
|
|
macro. Click on "Show Answer" to see the solution.
|
|
|
|
\begin{edXsolution}
|
|
Detroit is near Canada, but it is actually in the United States.
|
|
\end{edXsolution}
|
|
|
|
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
|
|
\subsection{Example "custom response" problem}
|
|
|
|
This problem demonstrates the use of a custom python script used for
|
|
checking the answer.
|
|
|
|
\begin{edXscript}
|
|
def sumtest(expect,ans):
|
|
(a1,a2) = map(float,eval(ans))
|
|
return (a1+a2)==10
|
|
\end{edXscript}
|
|
|
|
Enter a python list of two numbers which sum to 10, eg [9,1]:
|
|
|
|
\edXabox{expect="[1,9]" type="custom" cfn="sumtest"}
|
|
|
|
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
|
|
\subsection{Example image}
|
|
|
|
Include image by using the edXxml macro:
|
|
|
|
\edXxml{<img src="http://autoid.mit.edu/images/mit_dome.jpg"/>}
|
|
|
|
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
|

\subsection{Example show/hide explanation}
|
|
|
|
Extra explanations can be tucked away behind a "showhide" toggle flag:
|
|
|
|
\edXshowhide{sh1}{More explanation}{This is a hidden explanation. It
|
|
can contain equations: $\alpha = \frac{2}{\sqrt{1+\gamma}}$ }
|
|
|
|
This is some text after the showhide example.
