1.529 ! jms 29: =head1 NAME
! 30:
! 31: Apache::grades
! 32:
! 33: =head1 SYNOPSIS
! 34:
! 35: Handles the viewing of grades.
! 36:
! 37: This is part of the LearningOnline Network with CAPA project
! 38: described at http://www.lon-capa.org.
! 39:
! 40: =head1 OVERVIEW
! 41:
! 42: Do an ssi with retries:
! 43: While I'd love to factor out this with the vesrion in lonprintout,
! 44: that would either require a data coupling between modules, which I refuse to perpetuate (there's quite enough of that already), or would require the invention of another infrastructure
! 45: I'm not quite ready to invent (e.g. an ssi_with_retry object).
! 46:
! 47: At least the logic that drives this has been pulled out into loncommon.
! 48:
! 49:
! 50:
! 51: ssi_with_retries - Does the server side include of a resource.
! 52: if the ssi call returns an error we'll retry it up to
! 53: the number of times requested by the caller.
! 54: If we still have a proble, no text is appended to the
! 55: output and we set some global variables.
! 56: to indicate to the caller an SSI error occurred.
! 57: All of this is supposed to deal with the issues described
! 58: in LonCAPA BZ 5631 see:
! 59: http://bugs.lon-capa.org/show_bug.cgi?id=5631
! 60: by informing the user that this happened.
! 61:
! 62: Parameters:
! 63: resource - The resource to include. This is passed directly, without
! 64: interpretation to lonnet::ssi.
! 65: form - The form hash parameters that guide the interpretation of the resource
! 66:
! 67: retries - Number of retries allowed before giving up completely.
! 68: Returns:
! 69: On success, returns the rendered resource identified by the resource parameter.
! 70: Side Effects:
! 71: The following global variables can be set:
! 72: ssi_error - If an unrecoverable error occurred this becomes true.
! 73: It is up to the caller to initialize this to false
! 74: if desired.
! 75: ssi_error_resource - If an unrecoverable error occurred, this is the value
! 76: of the resource that could not be rendered by the ssi
! 77: call.
! 78: ssi_error_message - The error string fetched from the ssi response
! 79: in the event of an error.
! 80:

! 91:
! 92:
! 93: scantron_get_correction() :
! 94:
! 95: Builds the interface screen to interact with the operator to fix a
! 96: specific error condition in a specific scanline
! 97:
! 98: Arguments:
! 99: $r - Apache request object
! 100: $i - number of the current scanline
! 101: $scan_record - hash ref as returned from &scantron_parse_scanline()
! 102: $scan_config - hash ref as returned from &get_scantron_config()
! 103: $line - full contents of the current scanline
! 104: $error - error condition, valid values are
! 105: 'incorrectCODE', 'duplicateCODE',
! 106: 'doublebubble', 'missingbubble',
! 107: 'duplicateID', 'incorrectID'
! 108: $arg - extra information needed
! 109: For errors:
! 110: - duplicateID - paper number that this studentID was seen before on
! 111: - duplicateCODE - array ref of the paper numbers this CODE was
! 112: seen on before
! 113: - incorrectCODE - current incorrect CODE
! 114: - doublebubble - array ref of the bubble lines that have double
! 115: bubble errors
! 116: - missingbubble - array ref of the bubble lines that have missing
! 117: bubble errors
! 118:
! 119: =item *
! 120:
! 121: scantron_get_maxbubble() :
! 122:
! 123: Returns the maximum number of bubble lines that are expected to
! 124: occur. Does this by walking the selected sequence rendering the
! 125: resource and then checking &Apache::lonxml::get_problem_counter()
! 126: for what the current value of the problem counter is.
! 127:
! 128: Caches the results to $env{'form.scantron_maxbubble'},
! 129: $env{'form.scantron.bubble_lines.n'},
! 130: $env{'form.scantron.first_bubble_line.n'} and
! 131: $env{"form.scantron.sub_bubblelines.n"}
! 132: which are the total number of bubble, lines, the number of bubble
! 133: lines for response n and number of the first bubble line for response n,
! 134: and a comma separated list of numbers of bubble lines for sub-questions
! 135: (for optionresponse, matchresponse, and rankresponse items), for response n.

! 137:
! 138: =item *
! 139:
! 140: scantron_validate_missingbubbles() :
! 141:
! 142: Validates all scanlines in the selected file to not have any

! 144: to be bubble free.
! 145:
! 146: =item *
! 147:
! 148: scantron_process_students() :
! 149:
! 150: Routine that does the actual grading of the bubble sheet information.
! 151:
! 152: The parsed scanline hash is added to %env
! 153:
! 154: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
! 155: foreach resource , with the form data of
! 156:
! 157: 'submitted' =>'scantron'
! 158: 'grade_target' =>'grade',
! 159: 'grade_username'=> username of student
! 160: 'grade_domain' => domain of student
! 161: 'grade_courseid'=> of course
! 162: 'grade_symb' => symb of resource to grade
! 163:
! 164: This triggers a grading pass. The problem grading code takes care
! 165: of converting the bubbled letter information (now in %env) into a
! 166: valid submission.
! 167:
! 168: =item *
! 169:
! 170: scantron_upload_scantron_data() :

! 193: course.
! 194:

! 196:

4810: =head1 Bubble sheet grading routines
4811:
1.424 albertel 4812: For this documentation:
4813:
4814: 'scanline' refers to the full line of characters
4815: from the file that we are parsing that represents one entire sheet
4816:
4817: 'bubble line' refers to the data
4818: representing the line of bubbles that are on the physical bubble sheet
4819:
4820:
4821: The overall process is that a scanned in bubble sheet data is uploaded
4822: into a course. When a user wants to grade, they select a
4823: sequence/folder of resources, a file of bubble sheet info, and pick
4824: one of the predefined configurations for what each scanline looks
4825: like.
4826:
4827: Next each scanline is checked for any errors of either 'missing
1.435 foxr 4828: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 4829: because too light bubbling), 'double bubble' (each bubble line should
4830: have no more that one letter picked), invalid or duplicated CODE,
4831: invalid student ID
4832:
4833: If the CODE option is used that determines the randomization of the
4834: homework problems, either way the student ID is looked up into a
4835: username:domain.
4836:
4837: During the validation phase the instructor can choose to skip scanlines.
4838:
1.435 foxr 4839: After the validation phase, there are now 3 bubble sheet files
1.424 albertel 4840:
4841: scantron_original_filename (unmodified original file)
4842: scantron_corrected_filename (file where the corrected information has replaced the original information)
4843: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4844:
4845: Also there is a separate hash nohist_scantrondata that contains extra
4846: correction information that isn't representable in the bubble sheet
4847: file (see &scantron_getfile() for more information)
4848:
4849: After all scanlines are either valid, marked as valid or skipped, then
4850: foreach line foreach problem in the picked sequence, an ssi request is
4851: made that simulates a user submitting their selected letter(s) against
4852: the homework problem.
