5108: =head1 Bubble sheet grading routines
5109:
5110: For this documentation:
5111:
5112: 'scanline' refers to the full line of characters
5113: from the file that we are parsing that represents one entire sheet
5114:
5115: 'bubble line' refers to the data
5116: representing the line of bubbles that are on the physical bubblesheet
5117:
5118:
5119: The overall process is that a scanned in bubblesheet data is uploaded
5120: into a course. When a user wants to grade, they select a
5121: sequence/folder of resources, a file of bubblesheet info, and pick
5122: one of the predefined configurations for what each scanline looks
5123: like.
5124:
5125: Next each scanline is checked for any errors of either 'missing
5126: bubbles' (it's an error because it may have been mis-scanned
5127: because too light bubbling), 'double bubble' (each bubble line should
5128: have no more than one letter picked), invalid or duplicated CODE,
5129: invalid student/employee ID
5130:
5131: If the CODE option is used that determines the randomization of the
5132: homework problems, either way the student/employee ID is looked up into a
5133: username:domain.
5134:
5135: During the validation phase the instructor can choose to skip scanlines.
5136:
5137: After the validation phase, there are now 3 bubblesheet files
5138:
5139: scantron_original_filename (unmodified original file)
5140: scantron_corrected_filename (file where the corrected information has replaced the original information)
5141: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5142:
5143: Also there is a separate hash nohist_scantrondata that contains extra
5144: correction information that isn't representable in the bubblesheet
5145: file (see &scantron_getfile() for more information)
5146:
5147: After all scanlines are either valid, marked as valid or skipped, then
5148: foreach line foreach problem in the picked sequence, an ssi request is
5149: made that simulates a user submitting their selected letter(s) against
5150: the homework problem.

5912: Arguments:
5913: line - The text of the bubblesheet file line to process
5914: whichline - Line number
5915: scantron_config - Hash describing the format of the bubblesheet lines.
5916: scan_data - Hash of extra information about the scanline
5917: (see scantron_getfile for more information)
5918: just_header - True if should not process question answers but only
5919: the stuff to the left of the answers.
5920: randomorder - True if randomorder in use
5921: randompick - True if randompick in use
5922: sequence - Exam folder URL
5923: master_seq - Ref to array containing symbs in exam folder
5924: symb_to_resource - Ref to hash of symbs for resources in exam folder
5925: (corresponding values are resource objects)
5926: partids_by_symb - Ref to hash of symb -> array ref of partIDs
5927: orderedforcode - Ref to hash of arrays. keys are CODEs and values
5928: are refs to an array of resource objects, ordered
5929: according to order used for CODE, when randomorder
5930: and or randompick are in use.
5931: respnumlookup - Ref to hash mapping question numbers in bubble lines
5932: for current line to question number used for same question
5933: in "Master Sequence" (as seen by Course Coordinator).
5934: startline - Ref to hash where key is question number (0 is first)
5935: and value is number of first bubble line for current
5936: student or code-based randompick and/or randomorder.
5937: totalref - Ref of scalar used to score total number of bubble
5938: lines needed for responses in a scan line (used when
5939: randompick in use.
5940:
5941: Returns:
5942: Hash containing the result of parsing the scanline
5943:
5944: Keys are all proceeded by the string 'scantron.'
5945:
5946: CODE - the CODE in use for this scanline
5947: useCODE - 1 if the CODE is invalid but it usage has been forced
5948: by the operator
5949: CODE_ignore_dup - 1 if the CODE is a duplicated use when unique
5950: CODEs were selected, but the usage has been
5951: forced by the operator
5952: ID - student/employee ID
5953: PaperID - if used, the ID number printed on the sheet when the
5954: paper was scanned
5955: FirstName - first name from the sheet

5963: doubleerror - a list of bubble ranges that are considered to be answers
5964: to a single question that have more than one bubble filled in.
5965: Of the form questionnumber::firstbubblenumber:count
5966:
5967: In the above, count is the number of bubble responses in the
5968: input line needed to represent the possible answers to the question.
5969: e.g. a radioresponse with 15 choices in an answer sheet with 10 choices
5970: per line would have count = 2.
5971:
5972: maxquest - the number of the last bubble line that was parsed
5973:
5974: (<number> starts at 1)
5975: <number>.answer - zero or more letters representing the selected
5976: letters from the scanline for the bubble line
5977: <number>.
5978: if blank there was either no bubble or there where
5979: multiple bubbles, (consult the keys missingerror and

10379: =head1 NAME
10380:
10381: Apache::grades
10382:
10383: =head1 SYNOPSIS
10384:
10385: Handles the viewing of grades.
10386:
10387: This is part of the LearningOnline Network with CAPA project
10388: described at http://www.lon-capa.org.
10389:
10390: =head1 OVERVIEW
10391:
10392: Do an ssi with retries:
10393: While I'd love to factor out this with the version in lonprintout,
10394: 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
10395: I'm not quite ready to invent (e.g. an ssi_with_retry object).
10396:
10397: At least the logic that drives this has been pulled out into loncommon.
10398:
10399:
10400:
10401: ssi_with_retries - Does the server side include of a resource.
10402: if the ssi call returns an error we'll retry it up to
10403: the number of times requested by the caller.
10404: If we still have a problem, no text is appended to the
10405: output and we set some global variables.
10406: to indicate to the caller an SSI error occurred.
10407: All of this is supposed to deal with the issues described
10408: in LON-CAPA BZ 5631 see:
10409: http://bugs.lon-capa.org/show_bug.cgi?id=5631
10410: by informing the user that this happened.
10411:
10412: Parameters:
10413: resource - The resource to include. This is passed directly, without
10414: interpretation to lonnet::ssi.
10415: form - The form hash parameters that guide the interpretation of the resource
10416:
10417: retries - Number of retries allowed before giving up completely.
10418: Returns:
10419: On success, returns the rendered resource identified by the resource parameter.
10420: Side Effects:
10421: The following global variables can be set:
10422: ssi_error - If an unrecoverable error occurred this becomes true.
10423: It is up to the caller to initialize this to false
10424: if desired.
10425: ssi_error_resource - If an unrecoverable error occurred, this is the value
10426: of the resource that could not be rendered by the ssi
10427: call.
10428: ssi_error_message - The error string fetched from the ssi response
10429: in the event of an error.

10440: =head1 Routines to display previous version of a Task for a specific student
10441:
10442: Tasks are graded pass/fail. Students who have yet to pass a particular Task
10443: can receive another opportunity. Access to tasks is slot-based. If a slot
10444: requires a proctor to check-in the student, a new version of the Task will
10445: be created when the student is checked in to the new opportunity.
10446:
10447: If a particular student has tried two or more versions of a particular task,
10448: the submission screen provides a user with vgr privileges (e.g., a Course
10449: Coordinator) the ability to display a previous version worked on by the
10450: student. By default, the current version is displayed. If a previous version
10451: has been selected for display, submission data are only shown that pertain
10452: to that particular version, and the interface to submit grades is not shown.
