Support for extra extra hints texts (feedback, correction hints)
The updated version of the inclass-exam supports now extra hint texts for lecturers and students. These extra information is displayed after the question, and is used either for feedback to the student (e.g. Einsicht) or as information for the grader (evaluation guidelines, esp. useful when multiple graders are involved). It can be controlled via setup what kind of information the question author can provide. The providable feedback is controlled via the feedback level:
Feedback level - The feedback level can be * "full": two input fields for feedback for correct and incorrect answers * "single": single input fields for feedback * "none": no input field for feedback. - The feedback level is specified in the forms used in the pull down menus for creating "New" test items. - The feedback level is applicable to all test item types (SC, MC, Text, ShortText, Ordering, Upload, Composite, Pool) - The predefined setup is as follows: "single" is used for all item type, except for "Pool" questions (since the feedback is taken from the replacement question from the Pool) - Nothing has change here
Correction notes: - optionally, correction notes can be specified. Since in the past, the general feedback was not shown to the students, it was sometimes abused for correction hints for the lecturer. Therefore, we have now a separate field - Correction notes can be added to all item types (SC, MC, Text, ShortText, Ordering, Upload, Composite, Pool) and are turned on by default (except for Pool).
Visibility of general feedback and correction notes - general feedback is shown (when provided) * full exam-protocol is shown * filtering single question * filtering single submission (view with revision selection) * exam-review for students (Einsicht) - corrections notes are shown (when provided) * full exam-protocol is shown * filtering single question * filtering single submission (view with revision selection) - when general feedback is not provided, the exam protocol etc. looks as before - when correction notes are not provided, the exam protocol etc. looks as before
- Negative feedback is provided, * when percentage is known, and * percentage is < 50% - when negative feedback is displayed, the positive feedback is not displayed and vice versa
For composite questions, the system supports hint texts for the full composite question and additional ones for every single part.
Added support for restricting access to exams based on IP addresses.
In order to avoid the problem that students might participate on exams intended to be held e.g. on campus from at home, one can now restrict the access based on IP ranges. It is possible to restrict the access via multiple range blocks that can be predefined by the sysadmins. One could predefine e.g. IP range blocks for "Campus LAN", "On Site", "VPN", etc., which can be selected by lecturers for individual exams.
Every IP range block can be defined via multiple entries of disallowed and allowed IP ranges, where the addresses can be specified via IPv4 or IPv6 CIDR blocks (e.g. 127.208.0.0/16), or with wild cards or individual IP addresses. The usage of CIDR blocks requires an update to the updated version of NaviServer.
The IP restriction is used in the current implementation for restricting the regular start of the exam (proctored or non-proctored). Lecturers can still perform test runs for exams with restricted access.
