34: =head1 NAME
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.
1.12 raeburn 60: (c) those which a student could use to display or save content within
61: the course itself (outside the exam folder). Printouts and resources
62: fall into this category.
1.4 raeburn 63:
64: For communication blocking to be truly effective in preventing unwanted
65: communication, or access to online materials, online testing needs to
66: take place in a lab setting where use of tools outside LON-CAPA, and use
67: of web sites beyond LON-CAPA are unavailable.
68:
69: Access to specified folder(s) and/or resources in the course contents
1.12 raeburn 70: can be restricted for the duration of an exam.
1.4 raeburn 71:
72: Exam blocks are of two types:
73: (a) Blocks with a defined start and end date.
74: (b) Blocks associated with a timed interval set for a specific folder,
75: or resource.
76:
77: When a student attempts to use a collaboration or communication feature
78: which is currently blocked, information will be available about the
79: duration of the block, and the identity of the Course Coordinator who
80: set the block.
81:
82: Although LON-CAPA communication can be blocked during an exam, course
83: personnel with the 'evb' (evade blocking) privilege will continue to
84: receive LON-CAPA messages sent from students in a course with an active
85: block on messaging. Students will not be able to view messages sent by
86: other students in the same course for the duration of the blocking event.
87:
88: Because students may be enrolled in more than one LON-CAPA course at a time
89: it is important to use reasonable time windows for blocking events, or, in
90: the case of blocks triggered by clicking a button to start a timed quiz,
91: quiz durations that are of limited duration. This is especially important
92: when blocking prtfolio access, as other courses may require students to use
1.11 bisitz 93: the portfolio as a mechanism for submitting assignments.
1.4 raeburn 94:
95: Information about blocks in a course will be cached for 10 minutes, so,
96: as with parameters set for resources, it can take up to 10 minutes for
97: new blocks, or changes to existing blocks, to propagate to other servers.
98:
99: Changes to existing blocks on the server hosting your current session
100: are available immediately, as cached data on blocks is devalidated
101: automatically on the current server whenever a change is made to a
102: block (including deletion), or when a new block is added.
