HEAD
- Verification of Scantron grading for problems containing randomlists
- &scantron_partids_tograde()
- changed to use &get_analyze() to retrieve partIDs/responseIDs
- subroutine moved to be within scope of %analyze_cache.
- needs to be called for each user (randomlist -> possibly different responseIDs for different users).
- Robustness against changes to lonxml::counter being made by multitasking instructors.
- scantron_questnum_start.$part.$id form element passed in ssi call for scantron grading.
- where available, this value is used within response::getresponse() instead of lonxml::counter to determine starting column for scantron line.
- Second pass (if optional inbuilt verification enabled during scantron grading).
- Added missing call to repeat &grade_student_bubbles() when anomaly is detected during first pass.
****
Work-in-progress - possible performance hit - perhaps check if resource includes <randomlist></randomlist> before calling &scantron_partids_tograde() for each user?

4659: =head1 Bubble sheet grading routines
4660:
4661: For this documentation:
4662:
4663: 'scanline' refers to the full line of characters
4664: from the file that we are parsing that represents one entire sheet
4665:
4666: 'bubble line' refers to the data
4667: representing the line of bubbles that are on the physical bubble sheet
4668:
4669:
4670: The overall process is that a scanned in bubble sheet data is uploaded
4671: into a course. When a user wants to grade, they select a
4672: sequence/folder of resources, a file of bubble sheet info, and pick
4673: one of the predefined configurations for what each scanline looks
4674: like.
4675:
4676: Next each scanline is checked for any errors of either 'missing
4677: bubbles' (it's an error because it may have been mis-scanned
4678: because too light bubbling), 'double bubble' (each bubble line should
4679: have no more that one letter picked), invalid or duplicated CODE,
4680: invalid student ID
4681:
4682: If the CODE option is used that determines the randomization of the
4683: homework problems, either way the student ID is looked up into a
4684: username:domain.
4685:
4686: During the validation phase the instructor can choose to skip scanlines.
4687:
4688: After the validation phase, there are now 3 bubble sheet files
4689:
4690: scantron_original_filename (unmodified original file)
4691: scantron_corrected_filename (file where the corrected information has replaced the original information)
4692: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4693:
4694: Also there is a separate hash nohist_scantrondata that contains extra
4695: correction information that isn't representable in the bubble sheet
4696: file (see &scantron_getfile() for more information)
4697:
4698: After all scanlines are either valid, marked as valid or skipped, then
4699: foreach line foreach problem in the picked sequence, an ssi request is
4700: made that simulates a user submitting their selected letter(s) against
4701: the homework problem.

9025: =head1 NAME
9026:
9027: Apache::grades
9028:
9029: =head1 SYNOPSIS
9030:
9031: Handles the viewing of grades.
9032:
9033: This is part of the LearningOnline Network with CAPA project
9034: described at http://www.lon-capa.org.
9035:
9036: =head1 OVERVIEW
9037:
9038: Do an ssi with retries:
9039: While I'd love to factor out this with the vesrion in lonprintout,
9040: 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
9041: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9042:
9043: At least the logic that drives this has been pulled out into loncommon.
9044:
9045:
9046:
9047: ssi_with_retries - Does the server side include of a resource.
9048: if the ssi call returns an error we'll retry it up to
9049: the number of times requested by the caller.
9050: If we still have a proble, no text is appended to the
9051: output and we set some global variables.
9052: to indicate to the caller an SSI error occurred.
9053: All of this is supposed to deal with the issues described
9054: in LonCAPA BZ 5631 see:
9055: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9056: by informing the user that this happened.
9057:
9058: Parameters:
9059: resource - The resource to include. This is passed directly, without
9060: interpretation to lonnet::ssi.
9061: form - The form hash parameters that guide the interpretation of the resource
9062:
9063: retries - Number of retries allowed before giving up completely.
9064: Returns:
9065: On success, returns the rendered resource identified by the resource parameter.
9066: Side Effects:
9067: The following global variables can be set:
9068: ssi_error - If an unrecoverable error occurred this becomes true.
9069: It is up to the caller to initialize this to false
9070: if desired.
9071: ssi_error_resource - If an unrecoverable error occurred, this is the value
9072: of the resource that could not be rendered by the ssi
9073: call.
9074: ssi_error_message - The error string fetched from the ssi response
9075: in the event of an error.

9086: =item scantron_get_correction() :
9087:
9088: Builds the interface screen to interact with the operator to fix a
9089: specific error condition in a specific scanline
9090:
9091: Arguments:
9092: $r - Apache request object
9093: $i - number of the current scanline
9094: $scan_record - hash ref as returned from &scantron_parse_scanline()
9095: $scan_config - hash ref as returned from &get_scantron_config()
9096: $line - full contents of the current scanline
9097: $error - error condition, valid values are
9098: 'incorrectCODE', 'duplicateCODE',
9099: 'doublebubble', 'missingbubble',
9100: 'duplicateID', 'incorrectID'
9101: $arg - extra information needed
9102: For errors:
9103: - duplicateID - paper number that this studentID was seen before on
9104: - duplicateCODE - array ref of the paper numbers this CODE was
9105: seen on before
9106: - incorrectCODE - current incorrect CODE
9107: - doublebubble - array ref of the bubble lines that have double
9108: bubble errors
9109: - missingbubble - array ref of the bubble lines that have missing
9110: bubble errors
9111:
9112: =item scantron_get_maxbubble() :
9113:
9114: Returns the maximum number of bubble lines that are expected to
9115: occur. Does this by walking the selected sequence rendering the
9116: resource and then checking &Apache::lonxml::get_problem_counter()
9117: for what the current value of the problem counter is.
9118:
9119: Caches the results to $env{'form.scantron_maxbubble'},
9120: $env{'form.scantron.bubble_lines.n'},
9121: $env{'form.scantron.first_bubble_line.n'} and
9122: $env{"form.scantron.sub_bubblelines.n"}
9123: which are the total number of bubble, lines, the number of bubble
9124: lines for response n and number of the first bubble line for response n,
9125: and a comma separated list of numbers of bubble lines for sub-questions
9126: (for optionresponse, matchresponse, and rankresponse items), for response n.
9127:
9128:
9129: =item scantron_validate_missingbubbles() :
9130:
9131: Validates all scanlines in the selected file to not have any
9132: answers that don't have bubbles that have not been verified
9133: to be bubble free.
9134:
9135: =item scantron_process_students() :
9136:
9137: Routine that does the actual grading of the bubble sheet information.
9138:
9139: The parsed scanline hash is added to %env
9140:
9141: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
9142: foreach resource , with the form data of
9143:
9144: 'submitted' =>'scantron'
9145: 'grade_target' =>'grade',
9146: 'grade_username'=> username of student
9147: 'grade_domain' => domain of student
9148: 'grade_courseid'=> of course
9149: 'grade_symb' => symb of resource to grade
9150:
9151: This triggers a grading pass. The problem grading code takes care
9152: of converting the bubbled letter information (now in %env) into a
9153: valid submission.
9154:
9155: =item scantron_upload_scantron_data() :
9156:
9157: Creates the screen for adding a new bubble sheet data file to a course.
9158:
9159: =item scantron_upload_scantron_data_save() :
9160:
9161: Adds a provided bubble information data file to the course if user
9162: has the correct privileges to do so.
9163:
9164: =item valid_file() :
9165:
9166: Validates that the requested bubble data file exists in the course.
9167:
9168: =item scantron_download_scantron_data() :
9169:
9170: Shows a list of the three internal files (original, corrected,
9171: skipped) for a specific bubble sheet data file that exists in the
9172: course.
9173:
9174: =item scantron_validate_ID() :
9175:
9176: Validates all scanlines in the selected file to not have any
9177: invalid or underspecified student IDs
