5037: =head1 Bubble sheet grading routines
5038:
5039: For this documentation:
5040:
5041: 'scanline' refers to the full line of characters
5042: from the file that we are parsing that represents one entire sheet
5043:
5044: 'bubble line' refers to the data
5045: representing the line of bubbles that are on the physical bubblesheet
5046:
5047:
5048: The overall process is that a scanned in bubblesheet data is uploaded
5049: into a course. When a user wants to grade, they select a
5050: sequence/folder of resources, a file of bubblesheet info, and pick
5051: one of the predefined configurations for what each scanline looks
5052: like.
5053:
5054: Next each scanline is checked for any errors of either 'missing
5055: bubbles' (it's an error because it may have been mis-scanned
5056: because too light bubbling), 'double bubble' (each bubble line should
5057: have no more that one letter picked), invalid or duplicated CODE,
5058: invalid student/employee ID
5059:
5060: If the CODE option is used that determines the randomization of the
5061: homework problems, either way the student/employee ID is looked up into a
5062: username:domain.
5063:
5064: During the validation phase the instructor can choose to skip scanlines.
5065:
5066: After the validation phase, there are now 3 bubblesheet files
5067:
5068: scantron_original_filename (unmodified original file)
5069: scantron_corrected_filename (file where the corrected information has replaced the original information)
5070: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5071:
5072: Also there is a separate hash nohist_scantrondata that contains extra
5073: correction information that isn't representable in the bubblesheet
5074: file (see &scantron_getfile() for more information)
5075:
5076: After all scanlines are either valid, marked as valid or skipped, then
5077: foreach line foreach problem in the picked sequence, an ssi request is
5078: made that simulates a user submitting their selected letter(s) against
5079: the homework problem.

10264:
10265: Apache::grades
10266:
10267: =head1 SYNOPSIS
10268:
10269: Handles the viewing of grades.
10270:
10271: This is part of the LearningOnline Network with CAPA project
10272: described at http://www.lon-capa.org.
10273:
10274: =head1 OVERVIEW
10275:
10276: Do an ssi with retries:
10277: While I'd love to factor out this with the vesrion in lonprintout,
10278: 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
10279: I'm not quite ready to invent (e.g. an ssi_with_retry object).
10280:
10281: At least the logic that drives this has been pulled out into loncommon.
10282:
10283:
10284:
10285: ssi_with_retries - Does the server side include of a resource.
10286: if the ssi call returns an error we'll retry it up to
10287: the number of times requested by the caller.
10288: If we still have a proble, no text is appended to the
10289: output and we set some global variables.
10290: to indicate to the caller an SSI error occurred.
10291: All of this is supposed to deal with the issues described
10292: in LonCAPA BZ 5631 see:
10293: http://bugs.lon-capa.org/show_bug.cgi?id=5631
10294: by informing the user that this happened.
10295:
10296: Parameters:
10297: resource - The resource to include. This is passed directly, without
10298: interpretation to lonnet::ssi.
10299: form - The form hash parameters that guide the interpretation of the resource
10300:
10301: retries - Number of retries allowed before giving up completely.
10302: Returns:
10303: On success, returns the rendered resource identified by the resource parameter.
10304: Side Effects:
10305: The following global variables can be set:
10306: ssi_error - If an unrecoverable error occurred this becomes true.
10307: It is up to the caller to initialize this to false
10308: if desired.
10309: ssi_error_resource - If an unrecoverable error occurred, this is the value
10310: of the resource that could not be rendered by the ssi
10311: call.
10312: ssi_error_message - The error string fetched from the ssi response
10313: in the event of an error.

10323:
10324: =head1 Routines to display previous version of a Task for a specific student
10325:
10326: Tasks are graded pass/fail. Students who have yet to pass a particular Task
10327: can receive another opportunity. Access to tasks is slot-based. If a slot
10328: requires a proctor to check-in the student, a new version of the Task will
10329: be created when the student is checked in to the new opportunity.
10330:
10331: If a particular student has tried two or more versions of a particular task,
10332: the submission screen provides a user with vgr privileges (e.g., a Course
10333: Coordinator) the ability to display a previous version worked on by the
10334: student. By default, the current version is displayed. If a previous version
10335: has been selected for display, submission data are only shown that pertain
10336: to that particular version, and the interface to submit grades is not shown.

10353: =item choose_task_version_form()
10354:

10364: breadcrumbs etc., are displayed
10365:
10366: Output: 4
10367: current - student's current version
10368: displayed - student's version being displayed
10369: result - scalar containing HTML for web form used to switch to
10370: a different version (or a link to close window, if pop-up).
10371: js - javascript for processing selection in versions web form
10372:
10373: Side Effects: None.
10374:
10375: =item previous_display_javascript()
10376:

10380: current - student's current version number.
10381:

10439: $scantron_config - Reference to bubblesheet format configuration hash.
10440:
10441: Returns the maximum number of bubble lines that are expected to
10442: occur. Does this by walking the selected sequence rendering the
10443: resource and then checking &Apache::lonxml::get_problem_counter()
10444: for what the current value of the problem counter is.
10445:
10446: Caches the results to $env{'form.scantron_maxbubble'},
10447: $env{'form.scantron.bubble_lines.n'},
10448: $env{'form.scantron.first_bubble_line.n'} and
10449: $env{"form.scantron.sub_bubblelines.n"}
10450: which are the total number of bubble lines, the number of bubble
10451: lines for response n and number of the first bubble line for response n,
10452: and a comma separated list of numbers of bubble lines for sub-questions
10453: (for optionresponse, matchresponse, and rankresponse items), for response n.

10456: =item scantron_validate_missingbubbles() :
10457:
10458: Validates all scanlines in the selected file to not have any
10459: answers that don't have bubbles that have not been verified
10460: to be bubble free.
10461:
10462: =item scantron_process_students() :
10463:
10464: Routine that does the actual grading of the bubblesheet information.
10465:
10466: The parsed scanline hash is added to %env
10467:
10468: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
10469: foreach resource , with the form data of
10470:
10471: 'submitted' =>'scantron'
10472: 'grade_target' =>'grade',
10473: 'grade_username'=> username of student
10474: 'grade_domain' => domain of student
10475: 'grade_courseid'=> of course
10476: 'grade_symb' => symb of resource to grade
10477:
10478: This triggers a grading pass. The problem grading code takes care
10479: of converting the bubbled letter information (now in %env) into a
10480: valid submission.
10481:
10482: =item scantron_upload_scantron_data() :
10483:
10484: Creates the screen for adding a new bubblesheet data file to a course.
10485:
10486: =item scantron_upload_scantron_data_save() :
10487:
10488: Adds a provided bubble information data file to the course if user
10489: has the correct privileges to do so.
10490:
10491: =item valid_file() :
10492:
10493: Validates that the requested bubble data file exists in the course.
10494:
10495: =item scantron_download_scantron_data() :
10496:
10497: Shows a list of the three internal files (original, corrected,
10498: skipped) for a specific bubblesheet data file that exists in the
10499: course.
10500:
10501: =item scantron_validate_ID() :
10502:
10503: Validates all scanlines in the selected file to not have any
10504: invalid or underspecified student/employee IDs
10505:
10506: =item navmap_errormsg() :
10507:
10508: Returns HTML mark-up inside a <div></div> with a link to re-initialize the course.
10509: Should be called whenever the request to instantiate a navmap object fails.
