AMC-note - Online in the Cloud

PROGRAM:

NAME

AMC-note - computes marks after scans data capture for AMC multiple choice exams.

SYNOPSIS

auto-multiple-choice note --data project-data-dir [--seuil threshold]
[--grain granularity] [--arrondi rounding] [--notemin min]
[--notemax max] [--no-plafond | --plafond]

DESCRIPTION

The AMC-note.pl command computes marks for all students from the scoring strategy
extracted from the LaTeX source file by AMC-prepare(1) and from the data capture reports
made by AMC-analyse(1).

--data project-data-dir
gives the directory where data files are (see for example AMC-meptex(1)).

--seuil threshold
gives the black ratio threshold for deciding whether a box is ticked or not. When
deciding whether a box is checked or not, AMC-note.pl compares the black ratio (number
of black pixels over total number of pixels) to threshold. If the black ratio is
greater then threshold, the box is declared to be checked. Standard values can be 0.15
in the standard layout, or 0.5 for separate answer sheet layout (in this last case,
letters are drawn in the boxes, and the students are told to fill the boxes entirely).

--grain granularity --arrondi rounding
ask marks to be rounded to a multiple of granularity. If rounding is 'i', rounding is
done from below (as with floor(3)). If rounding is 'n', rounding is done to the
nearest multiple of granularity. If rounding is 's', rounding is done from above (as
with ceil(3)). For example, with options "--grain 0.25 --arrondi s", mark 6.285 is
rounded to 6.5.

--notemin min
with this option, all marks below min will be replaced by min.

--notemax max
gives the mark to associate to a sheet where all answers are correct. If not used,
marks are not scaled.

--plafond
with this option, all marks above max will be replaced by max.

--debug file.log
gives a file to fill with debugging information.

--postcorrect-student s --postcorrect-copy c
requests port-correction from the completed answer sheet identified by student and
copy numbers. In post-correction mode, correct answers are not extracted from the
LaTeX source file, but taken from the answers given on this sheet.
