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.

88: =over
89:
90: =item *
91:
92:
93: scantron_get_correction() :
94:
95: Builds the interface screen to interact with the operator to fix a
96: specific error condition in a specific scanline
97:
98: Arguments:
99: $r - Apache request object
100: $i - number of the current scanline
101: $scan_record - hash ref as returned from &scantron_parse_scanline()
102: $scan_config - hash ref as returned from &get_scantron_config()
103: $line - full contents of the current scanline
104: $error - error condition, valid values are
105: 'incorrectCODE', 'duplicateCODE',
106: 'doublebubble', 'missingbubble',
107: 'duplicateID', 'incorrectID'
108: $arg - extra information needed
109: For errors:
110: - duplicateID - paper number that this studentID was seen before on
111: - duplicateCODE - array ref of the paper numbers this CODE was
112: seen on before
113: - incorrectCODE - current incorrect CODE
114: - doublebubble - array ref of the bubble lines that have double
115: bubble errors
116: - missingbubble - array ref of the bubble lines that have missing
117: bubble errors
118:
119: =item *
120:
121: scantron_get_maxbubble() :
122:
123: Returns the maximum number of bubble lines that are expected to
124: occur. Does this by walking the selected sequence rendering the
125: resource and then checking &Apache::lonxml::get_problem_counter()
126: for what the current value of the problem counter is.
127:
128: Caches the results to $env{'form.scantron_maxbubble'},
129: $env{'form.scantron.bubble_lines.n'},
130: $env{'form.scantron.first_bubble_line.n'} and
131: $env{"form.scantron.sub_bubblelines.n"}
132: which are the total number of bubble, lines, the number of bubble
133: lines for response n and number of the first bubble line for response n,
134: and a comma separated list of numbers of bubble lines for sub-questions
135: (for optionresponse, matchresponse, and rankresponse items), for response n.
136:
137:
138: =item *
139:
140: scantron_validate_missingbubbles() :
141:
142: Validates all scanlines in the selected file to not have any
143: answers that don't have bubbles that have not been verified
144: to be bubble free.
145:
146: =item *
147:
148: scantron_process_students() :
149:
150: Routine that does the actual grading of the bubble sheet information.
151:
152: The parsed scanline hash is added to %env
153:
154: Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
155: foreach resource , with the form data of
156:
157: 'submitted' =>'scantron'
158: 'grade_target' =>'grade',
159: 'grade_username'=> username of student
160: 'grade_domain' => domain of student
161: 'grade_courseid'=> of course
162: 'grade_symb' => symb of resource to grade
163:
164: This triggers a grading pass. The problem grading code takes care
165: of converting the bubbled letter information (now in %env) into a
166: valid submission.
167:
168: =item *
169:
170: scantron_upload_scantron_data() :
171:
172: Creates the screen for adding a new bubble sheet data file to a course.
173:
174: =item *
175:
176: scantron_upload_scantron_data_save() :
177:
178: Adds a provided bubble information data file to the course if user
179: has the correct privileges to do so.
180:
181: =item *
182:
183: valid_file() :
184:
185: Validates that the requested bubble data file exists in the course.
186:
187: =item *
188:
189: scantron_download_scantron_data() :
190:
191: Shows a list of the three internal files (original, corrected,
192: skipped) for a specific bubble sheet data file that exists in the
193: course.
194:
195: =item *
196:
197: scantron_validate_ID() :
198:
199: Validates all scanlines in the selected file to not have any
200: invalid or underspecified student IDs

4810: =head1 Bubble sheet grading routines
4811:
4812: For this documentation:
4813:
4814: 'scanline' refers to the full line of characters
4815: from the file that we are parsing that represents one entire sheet
4816:
4817: 'bubble line' refers to the data
4818: representing the line of bubbles that are on the physical bubble sheet
4819:
4820:
4821: The overall process is that a scanned in bubble sheet data is uploaded
4822: into a course. When a user wants to grade, they select a
4823: sequence/folder of resources, a file of bubble sheet info, and pick
4824: one of the predefined configurations for what each scanline looks
4825: like.
4826:
4827: Next each scanline is checked for any errors of either 'missing
4828: bubbles' (it's an error because it may have been mis-scanned
4829: because too light bubbling), 'double bubble' (each bubble line should
4830: have no more that one letter picked), invalid or duplicated CODE,
4831: invalid student ID
4832:
4833: If the CODE option is used that determines the randomization of the
4834: homework problems, either way the student ID is looked up into a
4835: username:domain.
4836:
4837: During the validation phase the instructor can choose to skip scanlines.
4838:
4839: After the validation phase, there are now 3 bubble sheet files
4840:
4841: scantron_original_filename (unmodified original file)
4842: scantron_corrected_filename (file where the corrected information has replaced the original information)
4843: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4844:
4845: Also there is a separate hash nohist_scantrondata that contains extra
4846: correction information that isn't representable in the bubble sheet
4847: file (see &scantron_getfile() for more information)
4848:
4849: After all scanlines are either valid, marked as valid or skipped, then
4850: foreach line foreach problem in the picked sequence, an ssi request is
4851: made that simulates a user submitting their selected letter(s) against
4852: the homework problem.
