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

to write a factorial program.

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
114
right" (for example, write ``Hello world`` instead of ``Hello, world!``), and
115
press *Submit* again. It will tell you that you almost got it right. In this
116
way, the IVLE test framework can show users that they're on the right track.

First, click Submit, and note that the system automatically runs some test
120
cases, all of which fail. Now paste the solution to :func:`fac` (but not
121
:func:`main`). Clicking Submit again shows some test cases pass, but not all.
122
Finally, paste the solution to :func:`main`, and click Submit again. This
123
time, you will pass the test.

Log into IVLE as a lecturer (username: ``lecturer``, password: ``password``).
144
Many of these things are also possible as a tutor (try username: ``tutor``,
145
password: ``password``).
140
147
Being a lecturer or tutor is a per-subject privilege, so it only applies to
141
148
certain subjects. All of your special powers are under the subject home for
142
149
the subjects you are a tutor in. Note that everything a lecturer can do, an
143
150
admin can also do, for all subjects in the system.
145
Click "Intermediate IVLE - Subject home". From here, you will see largely the
146
same view as a student, but with more buttons. "Change details" allows you to
147
modify the subject properties. "Enrol users" allows you to add existing IVLE
148
users as students or tutors of the subject you are teaching (this is currently
149
an irreversible action).
152
Click *Intermediate IVLE – Subject home* (the one which does not display a
153
semester -- implying the currently active semester). From here, you will see
154
largely the same view as a student, but with more buttons. *Change details*
155
allows you to modify the subject properties. *Administer enrolments* allows
156
you to add existing IVLE users as students or tutors of the subject you are
157
teaching, change the roles of existing members, and revoke enrolments.

Click *Add a new project set* and enter a group size of 6. Then, create a
173
181
project in the new set. Each student must get into a new group for each
174
182
project *set*. Note also that the groups will share a Subversion repository
175
183
for all projects in a set, but if you create a new set, the students will have
176
184
to start using a new repository.
178
186
Usually, the hassle of getting into new groups and creating new repositories
179
means that you will want to create a single project set for a subject, and
180
just partition the projects into solo and group projects.
187
means that you will want to create just two project sets for a subject: one
188
for solo projects, and another for group projects.
193
Lecturers and tutors can view any student or group's project submission, using
194
an external Subversion client. As submissions are really just Subversion
195
commits, you can examine a student's work by simply checking out the correct
196
revision of the repository.
198
From the offering page, click *View submissions* under the project of interest.
199
This takes you to a page which lists the latest submissions from every student
200
(presumably you will just see the submission made by ``studenta`` earlier in
201
this tour). Next to each submission is a command line, beginning with
202
``svn co``. For instance, you might see the line::
204
svn co --username lecturer -r7 http://svn.ivle.localhost/users/studenta/ivle-102/phase1.html
206
Paste this line into a command-line (or, if you use a GUI Subversion client,
207
use the username, revision and URL given). Subversion will likely prompt for a
208
password. For the sample data, this password is ``password``, but in general, it
209
will **not** be your normal IVLE password. You can learn your Subversion
210
password by opening a Console in IVLE and typing::
213
ivle.config.Config()['user_info']['svn_pass']
215
This will check out the student's work into the current directory, to inspect.
217
You can also try to check out the group submission from Phase 2.
220
It is currently not possible to check out a single file (not a directory)
221
submission using the instructions given. Instead, run ``svn cat``, and
222
redirect the output into a file.

Viewing worksheet marks
262
-----------------------
264
You will probably have already noticed that the lecturer's worksheet view is
265
not quite like the student's. It has a table at the top which shows some
266
statistics about how students in this subject are going with each exercise.
267
(Depending on settings, tutors may also be able to access these stats.)
269
Lecturers (not tutors) can also get more specific feedback on individual
270
students by selecting "View worksheet marks" at the bottom of the subject
271
page. This shows the marks in each worksheet, and in the subject overall, for
272
each student, and can be used to calculate each student's final grade.
274
The "Download as CSV file" link provides these same statistics in CSV format,
275
which can be easily parsed.

An administrator's view

=======================

280
Log into IVLE as an admin (username: ``admin``, password: ``password``).
224
282
Administrator users in IVLE have significant privileges. Note, however, that
225
283
for technical reasons, admins cannot read or write other users' files. This
226
284
requires root access on the machine IVLE is installed on.
228
289
Firstly, pull down the IVLE menu (top-left). There is an additional item for
229
admins -- the "Users" page. This lists all users with an account in IVLE.
290
admins -- the *Users* page. This lists all users with an account in IVLE.
230
291
Clicking on a username takes you to the user's profile page. Try it with the
233
294
The profile page is exactly the same as the user himself would see it, but
234
with a few more buttons on the side. "Change password" is the same as the
235
user's own "Change password" page. However, "Reset password" is a special
295
with a few more buttons on the side. *Change password* is the same as the
296
user's own *Change password* page. However, *Reset password* is a special
236
297
admin page which lets you change a user's password without knowing the old
237
one. "Administer user" also lets you change administrative settings for the
298
one. *Administer user* also lets you change administrative settings for the
238
299
user, such as their full name (more formal than display name, which the user
239
300
themselves can change) and student ID. You can also add/remove admin status
240
301
for, or disable/enable (i.e., ban from IVLE) any user (except yourself, of
244
305
Use this with care. Making a user an admin gives them complete control over
245
306
the system. They could even revoke *your* admin rights!
247
Admin users also enjoy the same privileges as lecturers, for all subjects on
248
the system. In addition, admins can enrol users in a subject as lecturers
249
(this is the only way to become a lecturer). Go to the subject page for
250
"Advanced IVLE" and enrol the user "lecturer" as a Lecturer in the subject.
308
Administering subjects and offerings
309
------------------------------------
311
Admin users also enjoy the same privileges as lecturers, for all subject
312
offerings on the system. In addition, admins can enrol users in an offering as
313
lecturers (this is the only way to become a lecturer), and change or delete a
314
lecturer's enrolment. Go to the subject page for Advanced IVLE and enrol the
315
user ``lecturer`` as a lecturer in the subject.
317
Admins can also administer subjects. Here it is important to distinguish
318
between a "subject" (a course on a specific topic which is repeated over a
319
number of semesters or years) and an "offering" (a particular instance of a
320
subject, for one semester). Lecturers can administer *offerings* they are
321
enrolled in, but not *subjects*.
323
As an admin, go to the *Subjects* page. You will see a link *Manage subjects
324
and semesters*. The list at the top of the page shows all registered
325
subjects. Click *Create new subject* to create a brand new subject (i.e., a
326
new course). Call it "Introduction to Programming", with the URL name
327
``intro-prog`` and subject code 200101.
329
Now we have created a *subject* but not an *offering*, so nobody will be able
330
to teach or enrol in this subject. From the "Introduction to Programming"
331
page, click *Create new offering*. Select the semester in which the subject
332
will be first taught. If you wish to create the first offering of a semester
333
(e.g., 2011 semester 1), you will have to create a new semester first. Type
334
in a subject description. (Note that each offering has an independent
335
description.) Once you have created an offering, you can enrol lecturers, and
336
they can in turn enrol students.
338
Lecturers can take over administration duties of an offering (such as editing
339
the description and managing projects), however it remains the admin's duty to
340
administer the subjects, including creating new offerings each semester and
343
Administering semesters
344
-----------------------
346
An important duty of the administrator is controlling the *state* of each
347
semester. Return to the *Manage subjects and semesters* page. Note the
348
*Semesters* table contains a list of all known semesters, and whether they are
349
"past", "current" or "future".
352
IVLE could automatically create and manage semesters based on the system
353
clock, but it presently does not. That is because your institution may have
354
a different concept of a "semester" to ours. (For example, what are the
355
semester start and end dates?) IVLE has therefore been designed to require
356
admins to manually activate new semesters and disable old ones.
358
In the sample data, 2009 semester 2 is the "current" semester. Let us assume
359
that we are moving into the start of 2010. Edit 2009 semester 2 and set its
360
state to "Past". Then, edit 2010 semester 1 and set its state to "Current".
361
This affects the system in several ways. Mainly, it just changes the UI for
362
all users, in terms of which offerings are presented as "current".
365
Marking a semester as anything other than "current" will make it impossible
366
for students enrolled in offerings for that semester to submit projects.
367
Only do this after the semester has fully closed.
369
It is possible for multiple semesters to be marked as "current", if this is
370
desired. Therefore, there is no need to disable one semester before enabling
added
