4662: =head1 Bubble sheet grading routines
4663:
1.424 albertel 4664: For this documentation:
4665:
4666: 'scanline' refers to the full line of characters
4667: from the file that we are parsing that represents one entire sheet
4668:
4669: 'bubble line' refers to the data
4670: representing the line of bubbles that are on the physical bubble sheet
4671:
4672:
4673: The overall process is that a scanned in bubble sheet data is uploaded
4674: into a course. When a user wants to grade, they select a
4675: sequence/folder of resources, a file of bubble sheet info, and pick
4676: one of the predefined configurations for what each scanline looks
4677: like.
4678:
4679: Next each scanline is checked for any errors of either 'missing
1.435 foxr 4680: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 4681: because too light bubbling), 'double bubble' (each bubble line should
4682: have no more that one letter picked), invalid or duplicated CODE,
4683: invalid student ID
4684:
4685: If the CODE option is used that determines the randomization of the
4686: homework problems, either way the student ID is looked up into a
4687: username:domain.
4688:
4689: During the validation phase the instructor can choose to skip scanlines.
4690:
1.435 foxr 4691: After the validation phase, there are now 3 bubble sheet files
1.424 albertel 4692:
4693: scantron_original_filename (unmodified original file)
4694: scantron_corrected_filename (file where the corrected information has replaced the original information)
4695: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4696:
4697: Also there is a separate hash nohist_scantrondata that contains extra
4698: correction information that isn't representable in the bubble sheet
4699: file (see &scantron_getfile() for more information)
4700:
4701: After all scanlines are either valid, marked as valid or skipped, then
4702: foreach line foreach problem in the picked sequence, an ssi request is
4703: made that simulates a user submitting their selected letter(s) against
4704: the homework problem.

9028: =head1 NAME
9029:
9030: Apache::grades
9031:
9032: =head1 SYNOPSIS
9033:
9034: Handles the viewing of grades.
9035:
9036: This is part of the LearningOnline Network with CAPA project
9037: described at http://www.lon-capa.org.
9038:
9039: =head1 OVERVIEW
9040:
9041: Do an ssi with retries:
9042: While I'd love to factor out this with the vesrion in lonprintout,
9043: 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
9044: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9045:
9046: At least the logic that drives this has been pulled out into loncommon.
9047:
9048:
9049:
9050: ssi_with_retries - Does the server side include of a resource.
9051: if the ssi call returns an error we'll retry it up to
9052: the number of times requested by the caller.
9053: If we still have a proble, no text is appended to the
9054: output and we set some global variables.
9055: to indicate to the caller an SSI error occurred.
9056: All of this is supposed to deal with the issues described
9057: in LonCAPA BZ 5631 see:
9058: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9059: by informing the user that this happened.
9060:
9061: Parameters:
9062: resource - The resource to include. This is passed directly, without
9063: interpretation to lonnet::ssi.
9064: form - The form hash parameters that guide the interpretation of the resource
9065:
9066: retries - Number of retries allowed before giving up completely.
9067: Returns:
9068: On success, returns the rendered resource identified by the resource parameter.
9069: Side Effects:
9070: The following global variables can be set:
9071: ssi_error - If an unrecoverable error occurred this becomes true.
9072: It is up to the caller to initialize this to false
9073: if desired.
9074: ssi_error_resource - If an unrecoverable error occurred, this is the value
9075: of the resource that could not be rendered by the ssi
9076: call.
9077: ssi_error_message - The error string fetched from the ssi response
9078: in the event of an error.

9089: =item scantron_get_correction() :
9090:
9091: Builds the interface screen to interact with the operator to fix a
9092: specific error condition in a specific scanline
9093:
9094: Arguments:
9095: $r - Apache request object
9096: $i - number of the current scanline
9097: $scan_record - hash ref as returned from &scantron_parse_scanline()
9098: $scan_config - hash ref as returned from &get_scantron_config()
9099: $line - full contents of the current scanline
9100: $error - error condition, valid values are
9101: 'incorrectCODE', 'duplicateCODE',
9102: 'doublebubble', 'missingbubble',
9103: 'duplicateID', 'incorrectID'
9104: $arg - extra information needed
9105: For errors:
9106: - duplicateID - paper number that this studentID was seen before on
9107: - duplicateCODE - array ref of the paper numbers this CODE was
9108: seen on before
9109: - incorrectCODE - current incorrect CODE
9110: - doublebubble - array ref of the bubble lines that have double
9111: bubble errors
9112: - missingbubble - array ref of the bubble lines that have missing
9113: bubble errors
9114:
9115: =item scantron_get_maxbubble() :
9116:
9117: Returns the maximum number of bubble lines that are expected to
9118: occur. Does this by walking the selected sequence rendering the
9119: resource and then checking &Apache::lonxml::get_problem_counter()
9120: for what the current value of the problem counter is.
9121:
9122: Caches the results to $env{'form.scantron_maxbubble'},
9123: $env{'form.scantron.bubble_lines.n'},
9124: $env{'form.scantron.first_bubble_line.n'} and
9125: $env{"form.scantron.sub_bubblelines.n"}
9126: which are the total number of bubble, lines, the number of bubble
9127: lines for response n and number of the first bubble line for response n,
9128: and a comma separated list of numbers of bubble lines for sub-questions
9129: (for optionresponse, matchresponse, and rankresponse items), for response n.
9130:
9131:
9132: =item scantron_validate_missingbubbles() :
9133:
9134: Validates all scanlines in the selected file to not have any
9135: answers that don't have bubbles that have not been verified
9136: to be bubble free.
9137:
9138: =item scantron_process_students() :
9139:
9140: Routine that does the actual grading of the bubble sheet information.
9141:
9142: The parsed scanline hash is added to %env
9143:
9144: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
9145: foreach resource , with the form data of
9146:
9147: 'submitted' =>'scantron'
9148: 'grade_target' =>'grade',
9149: 'grade_username'=> username of student
9150: 'grade_domain' => domain of student
9151: 'grade_courseid'=> of course
9152: 'grade_symb' => symb of resource to grade
9153:
9154: This triggers a grading pass. The problem grading code takes care
9155: of converting the bubbled letter information (now in %env) into a
9156: valid submission.
9157:
9158: =item scantron_upload_scantron_data() :
9159:
9160: Creates the screen for adding a new bubble sheet data file to a course.
9161:
9162: =item scantron_upload_scantron_data_save() :
9163:
9164: Adds a provided bubble information data file to the course if user
9165: has the correct privileges to do so.
9166:
9167: =item valid_file() :
9168:
9169: Validates that the requested bubble data file exists in the course.
9170:
9171: =item scantron_download_scantron_data() :
9172:
9173: Shows a list of the three internal files (original, corrected,
9174: skipped) for a specific bubble sheet data file that exists in the
9175: course.
9176:
9177: =item scantron_validate_ID() :
