Click on *Intermediate IVLE – Subject Home* from the home screen (or, from

is one worksheet, Worksheet Basics. Clicking this takes you to the worksheet,
107

where students are challenged by Python questions.

After reading the worksheet, attempt the simple programming question, which is
110
to write a factorial program.

A sample solution follows::

After reading the worksheet, attempt the first simple programming question,

which is to write the "Hello world" program.

automatically runs a test case, which fails. Now change the code to be "almost
119
right" (for example, write ``Hello world`` instead of ``Hello, world!``), and
120
press *Submit* again. It will tell you that you almost got it right. In this

Many of these things are also possible as a tutor (try username: ``tutor``,

145
152
Being a lecturer or tutor is a per-subject privilege, so it only applies to
146
153
certain subjects. All of your special powers are under the subject home for
147
154
the subjects you are a tutor in. Note that everything a lecturer can do, an
148
155
admin can also do, for all subjects in the system.
150
Click "Intermediate IVLE - Subject home". From here, you will see largely the
151
same view as a student, but with more buttons. "Change details" allows you to
152
modify the subject properties. "Enrol users" allows you to add existing IVLE
153
users as students or tutors of the subject you are teaching (this is currently
154
an irreversible action).

159
largely the same view as a student, but with more buttons. *Change details*
160
allows you to modify the subject properties. *Administer enrolments* allows

clicking on *Add a new project* within that box. The fields should be fairly

171
self-explanatory.
166
You can't currently edit or delete a project after it has been created.
168
173
Group projects are complicated by what we call "project sets". A "project set"
169
174
is a set of group projects where the student groups are the same throughout.
170
175
For instance, you will see Phase 2 and Phase 3 inside the same project set
171
176
box. This means students will get into groups of 3 to submit Phase 2, and then
172
177
the same group will submit Phase 3.

Clicking "Manage groups" lets you put students into groups for a given project

184
project *set*. Note also that the groups will share a Subversion repository
180
185
for all projects in a set, but if you create a new set, the students will have
181
186
to start using a new repository.
189
You can't delete a project set after it has been created (this could cause
190
problems for groups and their repositories).
183
192
Usually, the hassle of getting into new groups and creating new repositories
184
193
means that you will want to create just two project sets for a subject: one
185
194
for solo projects, and another for group projects.

Paste this line into a command-line (or, if you use a GUI Subversion client,

Viewing worksheet marks
267
-----------------------
269
You will probably have already noticed that the lecturer's worksheet view is
270
not quite like the student's. It has a table at the top which shows some
271
statistics about how students in this subject are going with each exercise.
272
(Depending on settings, tutors may also be able to access these stats.)
274
Lecturers (not tutors) can also get more specific feedback on individual
275
students by selecting "View worksheet marks" at the bottom of the subject
276
page. This shows the marks in each worksheet, and in the subject overall, for
277
each student, and can be used to calculate each student's final grade.
280
The marks are calculated from the current time, by default. However,
281
normally, there is a cutoff time after which students cannot gain any
282
additional marks for worksheets. You can set this cutoff in the offering
283
edit page. Once set, the marks will be calculated based on submissions up
284
until that date, and students will be notified of the cutoff time.
286
The "Download as CSV file" link provides these same statistics in CSV format,
287
which can be easily parsed.

An administrator's view
259
290
=======================
261
Log into IVLE as an admin (username: 'admin', password: 'password').
292
Log into IVLE as an admin (username: ``admin``, password: ``password``).
263
294
Administrator users in IVLE have significant privileges. Note, however, that
264
295
for technical reasons, admins cannot read or write other users' files. This
265
296
requires root access on the machine IVLE is installed on.
267
301
Firstly, pull down the IVLE menu (top-left). There is an additional item for
268
admins -- the "Users" page. This lists all users with an account in IVLE.
269
Clicking on a username takes you to the user's profile page. Try it with the
302
admins -- the *Users* page. This lists all users with an account in IVLE, and
303
lets you create new ones. Clicking on a username takes you to the user's
304
profile page. Try it with the user ``lecturer``.
272
306
The profile page is exactly the same as the user himself would see it, but
273
with a few more buttons on the side. "Change password" is the same as the
274
user's own "Change password" page. However, "Reset password" is a special
307
with a few more buttons on the side. *Change password* is the same as the
308
user's own *Change password* page. However, *Reset password* is a special
275
309
admin page which lets you change a user's password without knowing the old
276
one. "Administer user" also lets you change administrative settings for the
310
one. *Administer user* also lets you change administrative settings for the
277
311
user, such as their full name (more formal than display name, which the user
278
312
themselves can change) and student ID. You can also add/remove admin status
279
313
for, or disable/enable (i.e., ban from IVLE) any user (except yourself, of
283
317
Use this with care. Making a user an admin gives them complete control over
284
318
the system. They could even revoke *your* admin rights!
286
Admin users also enjoy the same privileges as lecturers, for all subjects on
287
the system. In addition, admins can enrol users in a subject as lecturers
288
(this is the only way to become a lecturer). Go to the subject page for
289
"Advanced IVLE" and enrol the user "lecturer" as a Lecturer in the subject.
320
Administering subjects and offerings
321
------------------------------------
323
Admin users also enjoy the same privileges as lecturers, for all subject
324
offerings on the system. In addition, admins can enrol users in an offering as
325
lecturers (this is the only way to become a lecturer), and change or delete a
326
lecturer's enrolment. Go to the subject page for Advanced IVLE and enrol the
327
user ``lecturer`` as a lecturer in the subject.
329
Admins can also administer subjects. Here it is important to distinguish
330
between a "subject" (a course on a specific topic which is repeated over a
331
number of semesters or years) and an "offering" (a particular instance of a
332
subject, for one semester). Lecturers can administer *offerings* they are
333
enrolled in, but not *subjects*.
335
As an admin, go to the *Subjects* page. You will see a link *Manage subjects
336
and semesters*. The list at the top of the page shows all registered
337
subjects. Click *Create new subject* to create a brand new subject (i.e., a
338
new course). Call it "Introduction to Programming", with the URL name
339
``intro-prog`` and subject code 200101.
341
Now we have created a *subject* but not an *offering*, so nobody will be able
342
to teach or enrol in this subject. From the "Introduction to Programming"
343
page, click *Create new offering*. Select the semester in which the subject
344
will be first taught. If you wish to create the first offering of a semester
345
(e.g., 2011 semester 1), you will have to create a new semester first. Type
346
in a subject description. (Note that each offering has an independent
347
description.) Once you have created an offering, you can enrol lecturers, and
348
they can in turn enrol students.
350
Lecturers can take over administration duties of an offering (such as editing
351
the description and managing projects), however it remains the admin's duty to
352
administer the subjects, including creating new offerings each semester and
355
Administering semesters
356
-----------------------
358
An important duty of the administrator is controlling the *state* of each
359
semester. Return to the *Manage subjects and semesters* page. Note the
360
*Semesters* table contains a list of all known semesters, and whether they are
361
"past", "current" or "future".
364
IVLE could automatically create and manage semesters based on the system
365
clock, but it presently does not. That is because your institution may have
366
a different concept of a "semester" to ours. (For example, what are the
367
semester start and end dates?) IVLE has therefore been designed to require
368
admins to manually activate new semesters and disable old ones.
370
In the sample data, 2009 semester 2 is the "current" semester. Let us assume
371
that we are moving into the start of 2010. Edit 2009 semester 2 and set its
372
state to "Past". Then, edit 2010 semester 1 and set its state to "Current".
373
This affects the system in several ways. Mainly, it just changes the UI for
374
all users, in terms of which offerings are presented as "current".
377
Marking a semester as anything other than "current" will make it impossible
378
for students enrolled in offerings for that semester to submit projects.
379
Only do this after the semester has fully closed.
381
It is possible for multiple semesters to be marked as "current", if this is
382
desired. Therefore, there is no need to disable one semester before enabling
