AT THIS TIME THE USE OF THIS FUNCTION IS *NOT* RECOMMENDED |
|
|
|
Use lonnavmaps to build a data structure describing the order and |
|
assessment contents of each sequence in the current course. |
|
|
|
The returned structure is a hash reference. |
|
|
|
{ title => 'title', |
|
symb => 'symb', |
|
source => '/s/o/u/r/c/e', |
|
type => (container|assessment), |

parts => [11,13,15], # only for assessment |
|
response_ids => [12,14,16], # only for assessment |
|
contents => [........] # only for container |
|
} |
|
|
|
$hash->{'contents'} is a reference to an array of hashes of the same structure. |
|
|
|
Also returned are array references to the sequences and assessments contained |
|
in the course. |

Retrieve the current status of a students performance. $sname and |

If $courseid is undef it will be retrieved from the environment. |

The return structure is based on &Apache::lonnet::currentdump. If |

If $symb is specified, a hash of |

If no data is found for $symb, or if the student has not performance data, |
