lonspreadsheet |
| |
|
| |
=head1 SYNOPSIS |
| |
|
| |
Spreadsheet interface to internal LON-CAPA data |
| |
|
| |
=head1 DESCRIPTION |
| |
|
| |
Lonspreadsheet provides course coordinators the ability to manage their |
| |
students grades online. The students are able to view their own grades, but |
| |
not the grades of their peers. The spreadsheet is highly customizable, |
| |
offering the ability to use Perl code to manipulate data, as well as many |
| |
built-in functions. |
| |
|
| |
|
| |
=head2 Functions available to user of lonspreadsheet |
