1.529 jms 29: =head1 NAME
30:
31: Apache::grades
32:
33: =head1 SYNOPSIS
34:
35: Handles the viewing of grades.
36:
37: This is part of the LearningOnline Network with CAPA project
38: described at http://www.lon-capa.org.
39:
40: =head1 OVERVIEW
41:
42: Do an ssi with retries:
43: While I'd love to factor out this with the vesrion in lonprintout,
44: 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
45: I'm not quite ready to invent (e.g. an ssi_with_retry object).
46:
47: At least the logic that drives this has been pulled out into loncommon.
48:
49:
50:
51: ssi_with_retries - Does the server side include of a resource.
52: if the ssi call returns an error we'll retry it up to
53: the number of times requested by the caller.
54: If we still have a proble, no text is appended to the
55: output and we set some global variables.
56: to indicate to the caller an SSI error occurred.
57: All of this is supposed to deal with the issues described
58: in LonCAPA BZ 5631 see:
59: http://bugs.lon-capa.org/show_bug.cgi?id=5631
60: by informing the user that this happened.
61:
62: Parameters:
63: resource - The resource to include. This is passed directly, without
64: interpretation to lonnet::ssi.
65: form - The form hash parameters that guide the interpretation of the resource
66:
67: retries - Number of retries allowed before giving up completely.
68: Returns:
69: On success, returns the rendered resource identified by the resource parameter.
70: Side Effects:
71: The following global variables can be set:
72: ssi_error - If an unrecoverable error occurred this becomes true.
73: It is up to the caller to initialize this to false
74: if desired.
75: ssi_error_resource - If an unrecoverable error occurred, this is the value
76: of the resource that could not be rendered by the ssi
77: call.
78: ssi_error_message - The error string fetched from the ssi response
79: in the event of an error.

1.529 jms 91:
92: Builds the interface screen to interact with the operator to fix a
93: specific error condition in a specific scanline
94:
95: Arguments:
96: $r - Apache request object
97: $i - number of the current scanline
98: $scan_record - hash ref as returned from &scantron_parse_scanline()
99: $scan_config - hash ref as returned from &get_scantron_config()
100: $line - full contents of the current scanline
101: $error - error condition, valid values are
102: 'incorrectCODE', 'duplicateCODE',
103: 'doublebubble', 'missingbubble',
104: 'duplicateID', 'incorrectID'
105: $arg - extra information needed
106: For errors:
107: - duplicateID - paper number that this studentID was seen before on
108: - duplicateCODE - array ref of the paper numbers this CODE was
109: seen on before
110: - incorrectCODE - current incorrect CODE
111: - doublebubble - array ref of the bubble lines that have double
112: bubble errors
113: - missingbubble - array ref of the bubble lines that have missing
114: bubble errors
115:
1.530 ! jms 116: =item scantron_get_maxbubble() :
1.529 jms 117:
118: Returns the maximum number of bubble lines that are expected to
119: occur. Does this by walking the selected sequence rendering the
120: resource and then checking &Apache::lonxml::get_problem_counter()
121: for what the current value of the problem counter is.
122:
123: Caches the results to $env{'form.scantron_maxbubble'},
124: $env{'form.scantron.bubble_lines.n'},
125: $env{'form.scantron.first_bubble_line.n'} and
126: $env{"form.scantron.sub_bubblelines.n"}
127: which are the total number of bubble, lines, the number of bubble
128: lines for response n and number of the first bubble line for response n,
129: and a comma separated list of numbers of bubble lines for sub-questions
130: (for optionresponse, matchresponse, and rankresponse items), for response n.
131:
132:
1.530 ! jms 133: =item scantron_validate_missingbubbles() :
1.529 jms 134:
135: Validates all scanlines in the selected file to not have any
136: answers that don't have bubbles that have not been verified
137: to be bubble free.
138:
1.530 ! jms 139: =item scantron_process_students() :
1.529 jms 140:
141: Routine that does the actual grading of the bubble sheet information.
142:
143: The parsed scanline hash is added to %env
144:
145: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
146: foreach resource , with the form data of
147:
148: 'submitted' =>'scantron'
149: 'grade_target' =>'grade',
150: 'grade_username'=> username of student
151: 'grade_domain' => domain of student
152: 'grade_courseid'=> of course
153: 'grade_symb' => symb of resource to grade
154:
155: This triggers a grading pass. The problem grading code takes care
156: of converting the bubbled letter information (now in %env) into a
157: valid submission.
158:
1.530 ! jms 159: =item scantron_upload_scantron_data() :
1.529 jms 160:
161: Creates the screen for adding a new bubble sheet data file to a course.
162:
1.530 ! jms 163: =item scantron_upload_scantron_data_save() :
1.529 jms 164:
165: Adds a provided bubble information data file to the course if user
166: has the correct privileges to do so.
167:
1.530 ! jms 168: =item valid_file() :
1.529 jms 169:

171:
1.530 ! jms 172: =item scantron_download_scantron_data() :
1.529 jms 173:
174: Shows a list of the three internal files (original, corrected,
175: skipped) for a specific bubble sheet data file that exists in the
176: course.
177:
1.530 ! jms 178: =item scantron_validate_ID() :

4791: =head1 Bubble sheet grading routines
4792:
1.424 albertel 4793: For this documentation:
4794:
4795: 'scanline' refers to the full line of characters
4796: from the file that we are parsing that represents one entire sheet
4797:
4798: 'bubble line' refers to the data
4799: representing the line of bubbles that are on the physical bubble sheet
4800:
4801:
4802: The overall process is that a scanned in bubble sheet data is uploaded
4803: into a course. When a user wants to grade, they select a
4804: sequence/folder of resources, a file of bubble sheet info, and pick
4805: one of the predefined configurations for what each scanline looks
4806: like.
4807:
4808: Next each scanline is checked for any errors of either 'missing
1.435 foxr 4809: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 4810: because too light bubbling), 'double bubble' (each bubble line should
4811: have no more that one letter picked), invalid or duplicated CODE,
4812: invalid student ID
4813:
4814: If the CODE option is used that determines the randomization of the
4815: homework problems, either way the student ID is looked up into a
4816: username:domain.
4817:
4818: During the validation phase the instructor can choose to skip scanlines.
4819:
1.435 foxr 4820: After the validation phase, there are now 3 bubble sheet files
1.424 albertel 4821:
4822: scantron_original_filename (unmodified original file)
4823: scantron_corrected_filename (file where the corrected information has replaced the original information)
4824: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4825:
4826: Also there is a separate hash nohist_scantrondata that contains extra
4827: correction information that isn't representable in the bubble sheet
4828: file (see &scantron_getfile() for more information)
4829:
4830: After all scanlines are either valid, marked as valid or skipped, then
4831: foreach line foreach problem in the picked sequence, an ssi request is
4832: made that simulates a user submitting their selected letter(s) against
4833: the homework problem.
