Added Drag and Drop interface for feedback files

- When grading a student, feedback files can be added via drag and drop

- Caution was spent to avoid potentially slow refresh operations on

log exam protocols. All interactions use AJAX and update the

DOM tree directly

- The feedback files are displayed as thumbnails

- When permissions allow, the thumbnail files can be directly viewed and/or deleted

- Supports Bootstrap3 and Bootstrap 5

- Support for composite questions.

- bumped version number to 5.10.1d43

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.

Version number bumped to 5.10.1d32

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.

Added support for www-toggle-publish-status

This is needed to avoid a bad interaction with [ad_return_url] as it

is used in www-toggle-publish-status in xowiki, since the workflow

definition unsets the actual return_url, which causes ad_return_url to

use the URL leading to this call (m=toggle-publish-status), causing a

redirection loop.

Version number bumped to 5.10.1d28

Store statistics in a separate page instead of the workflow itself

- advantages:

* smaller workflow instance

- no danger that page is too large for caching, even for large exams.

- smaller objects mean also better performance

* modification date in exam is not modified when statistics

are updated

* easier extensible

- New function WorkflowPage->childpage

easy to use interface for creating child pages

- render_submission=exam_protocol: changed name of

parameter "-form_objs" to "-filter_form_ids", since

form_objs are used typically to keep objects, not ids

- Still to do: policy for inclass-exam-statistics.wf

- Bumped version number to 5.10.1d25

added a test for checking the results of the preview of test-items

Since the preview workflow requires a multiple redirects, xowiki::test::edit_form_page

requires a new flag refetch to actually turn off automatic refetching of the result

page, since this does not give us access to the redirect location returned by

the edit command.

Improved configurability of inclass exam

- added modal window for showing all configuration options

- depending on the state of an exam (whether students have stated

working on the exam or not) different options can be

altered. E.g. the grading scheme can be adjusted at any time, since

it is not visible to students prior to exam review.

- improved configurability of form-fields:

. new feature: fc_repository for shared definitions

(can be reused in the same configuration on multiple occasions)

. when form-constraints are defined with an empty short-spec,

the system tries to look this up from the fc_repository.

- extended answer manager:

. new method: student_submissions_exist

. renamed methods

. "student_submissions" -> "submissions"

(since result my include as well test run results)

. "get_answers" -> "get_answer_attributes"

to better distinguish from "submissions"

- base "merge_constraints" on dicts

- prefer forwarder over instance variable for referring

the question manager(QM)

- extended Message keys with "Configuration"

- added missing German translations in message keys

- bump version to 5.10.1d17

Added support for user-supplied grading schemes

Grading schemes provide a means to map achieved percentages to a numeric grade.

In the current versions, a fixed number of 5 grades is supported.

A grading scheme consists of a grounding scheme and grading boundaries.

- A grading scheme can be selected at exam definition time

- Lecturers can define their own grading schemes and reuse these between exams

- Available grounding schemes:

* no rounding (recommended for small exams, e.g. 5 minutes or 2 points)

* by percent (the calculated percentages are rounded to the provided number of digits)

* by points (the calculated points are rounded to the provided number of digits)

- The grounding precision can be defined by the user (e.g. to 2 digits)

- The grading boundaries represent percentages boundaries necessary for a certain grade

- When selecting no grading scheme, no grading information is provided in the exam protocol

(just percentages)

More changes:

- allow grading also, when student has not submitted the exam

- added percentage information in the grading-box (esp. useful for composite questions)

- renamed predefined grading schemes to more neutral terms

- provide easy-to-type names for question-manager, answer-manager and form-loader

- new utility for more robust list-comparions

- defined validating form-field type for grading boundaries
