- Bug 6450. Course personnel with vgr priv can view student's prior
versions of a Bridge Task (BT).
- bridgetask.pm
- generation of Show Slot list and Show Grading Status buttons moved
to new routine: &add_slotlist_button().
- "Show Slot list", "Show Grading Status", "Show a previously done version"
"Get a submission to grade", "Change reservation" buttons not shown
when course personnel display student's version of a BT.
- ensure tags have unique ids (replace duplicate LC_task_feedback with
LC_task_answer.
- grades.pm
- Header: "View of the problem" replaced with "View of the problem for
<student name>
- Header: "Correct answer" replaced with "Correct answer for "
<student name>
- New routine: &show_previous_task_version() to show student's previous
version of a BT.
- New routine: &choose_task_version_form() provides a web form to select
display of a student's version of a BT (in same window or in pop-up).
- New routine: &previous_display_javascript() javascript to launch pop-up
etc. for other version.
- &startpage() has four additional args: $stuvcurrent,$stuvdisp,$nomenu,$js
student's current BT version, version being displayed, no page menu (for
pop-up), and javascript to launch previous version pop-up.a
- lonhtmlcommon.pm
- &resource_info_box() has two additional args: $stuvcurrent,$stuvdisp
student's current BT version, and version being displayed.

5033: =head1 Bubble sheet grading routines
5034:
5035: For this documentation:
5036:
5037: 'scanline' refers to the full line of characters
5038: from the file that we are parsing that represents one entire sheet
5039:
5040: 'bubble line' refers to the data
5041: representing the line of bubbles that are on the physical bubblesheet
5042:
5043:
5044: The overall process is that a scanned in bubblesheet data is uploaded
5045: into a course. When a user wants to grade, they select a
5046: sequence/folder of resources, a file of bubblesheet info, and pick
5047: one of the predefined configurations for what each scanline looks
5048: like.
5049:
5050: Next each scanline is checked for any errors of either 'missing
5051: bubbles' (it's an error because it may have been mis-scanned
5052: because too light bubbling), 'double bubble' (each bubble line should
5053: have no more that one letter picked), invalid or duplicated CODE,
5054: invalid student/employee ID
5055:
5056: If the CODE option is used that determines the randomization of the
5057: homework problems, either way the student/employee ID is looked up into a
5058: username:domain.
5059:
5060: During the validation phase the instructor can choose to skip scanlines.
5061:
5062: After the validation phase, there are now 3 bubblesheet files
5063:
5064: scantron_original_filename (unmodified original file)
5065: scantron_corrected_filename (file where the corrected information has replaced the original information)
5066: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
5067:
5068: Also there is a separate hash nohist_scantrondata that contains extra
5069: correction information that isn't representable in the bubblesheet
5070: file (see &scantron_getfile() for more information)
5071:
5072: After all scanlines are either valid, marked as valid or skipped, then
5073: foreach line foreach problem in the picked sequence, an ssi request is
5074: made that simulates a user submitting their selected letter(s) against
5075: the homework problem.

9827: =head1 NAME
9828:
9829: Apache::grades
9830:
9831: =head1 SYNOPSIS
9832:
9833: Handles the viewing of grades.
9834:
9835: This is part of the LearningOnline Network with CAPA project
9836: described at http://www.lon-capa.org.
9837:
9838: =head1 OVERVIEW
9839:
9840: Do an ssi with retries:
9841: While I'd love to factor out this with the vesrion in lonprintout,
9842: 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
9843: I'm not quite ready to invent (e.g. an ssi_with_retry object).
9844:
9845: At least the logic that drives this has been pulled out into loncommon.
9846:
9847:
9848:
9849: ssi_with_retries - Does the server side include of a resource.
9850: if the ssi call returns an error we'll retry it up to
9851: the number of times requested by the caller.
9852: If we still have a proble, no text is appended to the
9853: output and we set some global variables.
9854: to indicate to the caller an SSI error occurred.
9855: All of this is supposed to deal with the issues described
9856: in LonCAPA BZ 5631 see:
9857: http://bugs.lon-capa.org/show_bug.cgi?id=5631
9858: by informing the user that this happened.
9859:
9860: Parameters:
9861: resource - The resource to include. This is passed directly, without
9862: interpretation to lonnet::ssi.
9863: form - The form hash parameters that guide the interpretation of the resource
9864:
9865: retries - Number of retries allowed before giving up completely.
9866: Returns:
9867: On success, returns the rendered resource identified by the resource parameter.
9868: Side Effects:
9869: The following global variables can be set:
9870: ssi_error - If an unrecoverable error occurred this becomes true.
9871: It is up to the caller to initialize this to false
9872: if desired.
9873: ssi_error_resource - If an unrecoverable error occurred, this is the value
9874: of the resource that could not be rendered by the ssi
9875: call.
9876: ssi_error_message - The error string fetched from the ssi response
9877: in the event of an error.

9885:
9886: =over
9887:
9888: =head1 Routines to display previous version of a Task for a specific student
9889:
9890: Tasks are graded pass/fail. Students who have yet to pass a particular Task
9891: can receive another opportunity. Access to tasks is slot-based. If a slot
9892: requires a proctor to check-in the student, a new version of the Task will
9893: be created when the student is checked in to the new opportunity.
9894:
9895: If a particular student has tried two or more versions of a particular task,
9896: the submission screen provides a user with vgr privileges (e.g., a Course
9897: Coordinator) the ability to display a previous version worked on by the
9898: student. By default, the current version is displayed. If a previous version
9899: has been selected for display, submission data are only shown that pertain
9900: to that particular version, and the interface to submit grades is not shown.
9901:
9902: =over 4
9903:
9904: =item show_previous_task_version()
9905:
9906: Displays a specified version of a student's Task, as the student sees it.
9907:
9908: Inputs: 2
9909: request - request object
9910: symb - unique symb for current instance of resource
9911:
9912: Output: None.
9913:
9914: Side Effects: calls &show_problem() to print version of Task, with
9915: version contained in form item: $env{'form.previousversion'}
9916:
9917: =item choose_task_version_form()
9918:
9919: Displays a web form used to select which version of a student's view of a
9920: Task should be displayed. Either launches a pop-up window, or replaces
9921: content in existing pop-up, or replaces page in main window.
9922:
9923: Inputs: 4
9924: symb - unique symb for current instance of resource
9925: uname - username of student
9926: udom - domain of student
9927: nomenu - 1 if display is in a pop-up window, and hence no menu
9928: breadcrumbs etc., are displayed
9929:
9930: Output: 4
9931: current - student's current version
9932: displayed - student's version being displayed
9933: result - scalar containing HTML for web form used to switch to
9934: a different version (or a link to close window, if pop-up).
9935: js - javascript for processing selection in versions web form
9936:
9937: Side Effects: None.
9938:
9939: =item previous_display_javascript()
9940:
9941: Inputs: 2
9942: nomenu - 1 if display is in a pop-up window, and hence no menu
9943: breadcrumbs etc., are displayed.
9944: current - student's current version number.
9945:
9946: Output: 1
9947: js - javascript for processing selection in versions web form.
9948:
9949: Side Effects: None.

9967: $line - full contents of the current scanline
9968: $error - error condition, valid values are
9969: 'incorrectCODE', 'duplicateCODE',
9970: 'doublebubble', 'missingbubble',
9971: 'duplicateID', 'incorrectID'
9972: $arg - extra information needed
9973: For errors:
9974: - duplicateID - paper number that this studentID was seen before on
9975: - duplicateCODE - array ref of the paper numbers this CODE was
9976: seen on before
9977: - incorrectCODE - current incorrect CODE

9983: =item scantron_get_maxbubble() :
9984:
9985: Arguments:
9986: $nav_error - Reference to scalar which is a flag to indicate a
9987: failure to retrieve a navmap object.
9988: if $nav_error is set to 1 by scantron_get_maxbubble(), the
9989: calling routine should trap the error condition and display the warning
9990: found in &navmap_errormsg().
9991:
9992: $scantron_config - Reference to bubblesheet format configuration hash.
9993:
9994: Returns the maximum number of bubble lines that are expected to
9995: occur. Does this by walking the selected sequence rendering the
9996: resource and then checking &Apache::lonxml::get_problem_counter()
9997: for what the current value of the problem counter is.
9998:
9999: Caches the results to $env{'form.scantron_maxbubble'},
10000: $env{'form.scantron.bubble_lines.n'},
10001: $env{'form.scantron.first_bubble_line.n'} and
10002: $env{"form.scantron.sub_bubblelines.n"}
10003: which are the total number of bubble, lines, the number of bubble
10004: lines for response n and number of the first bubble line for response n,
10005: and a comma separated list of numbers of bubble lines for sub-questions
10006: (for optionresponse, matchresponse, and rankresponse items), for response n.
10007:
10008:
10009: =item scantron_validate_missingbubbles() :
10010:
10011: Validates all scanlines in the selected file to not have any
10012: answers that don't have bubbles that have not been verified
10013: to be bubble free.
10014:
10015: =item scantron_process_students() :
10016:
10017: Routine that does the actual grading of the bubblesheet information.
10018:
10019: The parsed scanline hash is added to %env
10020:
10021: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
10022: foreach resource , with the form data of
10023:
10024: 'submitted' =>'scantron'
10025: 'grade_target' =>'grade',
10026: 'grade_username'=> username of student
10027: 'grade_domain' => domain of student
10028: 'grade_courseid'=> of course
10029: 'grade_symb' => symb of resource to grade
10030:
10031: This triggers a grading pass. The problem grading code takes care
10032: of converting the bubbled letter information (now in %env) into a
10033: valid submission.
10034:
10035: =item scantron_upload_scantron_data() :
10036:
10037: Creates the screen for adding a new bubblesheet data file to a course.
10038:
10039: =item scantron_upload_scantron_data_save() :
10040:
10041: Adds a provided bubble information data file to the course if user
10042: has the correct privileges to do so.
10043:
10044: =item valid_file() :
10045:
10046: Validates that the requested bubble data file exists in the course.
10047:
10048: =item scantron_download_scantron_data() :
10049:
10050: Shows a list of the three internal files (original, corrected,
10051: skipped) for a specific bubblesheet data file that exists in the
10052: course.
10053:
10054: =item scantron_validate_ID() :
10055:
10056: Validates all scanlines in the selected file to not have any
10057: invalid or underspecified student/employee IDs
10058:
10059: =item navmap_errormsg() :
10060:
10061: Returns HTML mark-up inside a <div></div> with a link to re-initialize the course.
10062: Should be called whenever the request to instantiate a navmap object fails.
