35:
36: lonblockingmenu - Handler to set/modify exam blocks in a course.
37:
38: =head1 SYNOPSIS
39:
40: lonblockingmenu provides an interface for setting exam blocks in a course.
41:
42: =head1 DESCRIPTION
43:
44: This module is used to configure blocking of access to collaborative tools
45: and/or resources during an exam.
46:
1.4 raeburn 47: =head1 OVERVIEW
48:
49: To support high-stakes testing, LON-CAPA provides Coordinators with the
50: ability to disable communication and collaborative features within the
51: system for the duration of an exam.
52:
53: Features which can be disabled include:
54: (a) those which a student could use to communicate with another student.
55: Messaging, discussion, chat, blogs, and some functionality in groups fall
56: into this category.
57: (b) those which a student could use to access materials prepared by the
58: student in advance of an exam, (e.g., for use during an online exam, to
59: gain an unfair advantage). Blogs and portfolio fall into this category.
60:
61: For communication blocking to be truly effective in preventing unwanted
62: communication, or access to online materials, online testing needs to
63: take place in a lab setting where use of tools outside LON-CAPA, and use
64: of web sites beyond LON-CAPA are unavailable.
65:
66: Access to specified folder(s) and/or resources in the course contents
67: can also be restricted for the duration of an exam.
68:
69: Exam blocks are of two types:
70: (a) Blocks with a defined start and end date.
71: (b) Blocks associated with a timed interval set for a specific folder,
72: or resource.
73:
74: When a student attempts to use a collaboration or communication feature
75: which is currently blocked, information will be available about the
76: duration of the block, and the identity of the Course Coordinator who
77: set the block.
78:
79: Although LON-CAPA communication can be blocked during an exam, course
80: personnel with the 'evb' (evade blocking) privilege will continue to
81: receive LON-CAPA messages sent from students in a course with an active
82: block on messaging. Students will not be able to view messages sent by
83: other students in the same course for the duration of the blocking event.
84:
85: Because students may be enrolled in more than one LON-CAPA course at a time
86: it is important to use reasonable time windows for blocking events, or, in
87: the case of blocks triggered by clicking a button to start a timed quiz,
88: quiz durations that are of limited duration. This is especially important
89: when blocking prtfolio access, as other courses may require students to use
90: the portfolio as a mechanism for submitting assigments.
91:
92: Information about blocks in a course will be cached for 10 minutes, so,
93: as with parameters set for resources, it can take up to 10 minutes for
94: new blocks, or changes to existing blocks, to propagate to other servers.
95:
96: Changes to existing blocks on the server hosting your current session
97: are available immediately, as cached data on blocks is devalidated
98: automatically on the current server whenever a change is made to a
99: block (including deletion), or when a new block is added.
