Philosophy
• CITS1401 is a first programming unit
– No prior programming experience is assumed
– But there is a wide range of student backgrounds
• CITS1401 is the first in a series of units
designed to give you
– Excellent problem-solving skills
– A good understanding of the programming process
– Exposure to a wide range of topics in ICT
Problem solving and programming are like
swimming and juggling: practice is everything!

Workshop
• Workshops are at 2–3 pm Tuesdays in Blakers LT,
starting in Week 2
• Purely optional on an as-needed basis
– Aimed at students who are having difficulty with
the content or the pace of the unit material
– Basic questions will be given priority over
more-advanced questions
– Additional examples complementing the lectures
– Embarrassment-free zone!
The only stupid question is the one that isn’t asked!

Online
• Everything that is distributed in CITS1401
will be available from
http://undergraduate.csse.uwa.edu.au/courses/CITS1401
– The only exception is that the lecture recordings
and slides are available via LMS
• Nothing else will be available via LMS
• To make a query in CITS1401, or to initiate
discussion on any relevant topic, go to

help1401
• Online discussion forum for CITS1401,
based on the philosophy of
READ FIRST: if the answer is not there, THEN POST
• Asking questions is useful:
– Sometimes just formulating a question properly
helps you to realise the answer yourself!
• Answering questions is useful:
– Explaining something helps you to understand it
DO NOT post code to help1401 if it is relevant to an assessment

Announcements
• Announcements will be made in three places
– In CITS1401 lectures
– On the CITS1401 web-site noticeboard
– On help1401
When an announcement has been made in these
three places, we will assume that you are aware of it.
• Any information distributed by email
will be sent to your UWA account
– Check your account regularly, or forward it

Development environment
• In the lab you will be using the Python 3.2 IDLE
available from python.org
– An integrated software environment where you can
create, edit, debug, and execute programs
• You can download this software free from
python.org and install it at home
– It is available for all major operating systems
Note that all work submitted for assessment
will be tested on the lab set-up

Assessment
• Assessment is based on both
– understanding of fundamental concepts
– practical problem-solving and programming skills
• Mid-semester test
– In the lecture on 16 April (Week 7), worth 15%
• Two programming projects
– Project 1 due in Week 8, worth 10%
– Project 2 due in Week 13, worth 15%
• Final exam
– In the June exam period, worth 60%

Passing and satisfactory progress
• To pass CITS1401, you must achieve
– At least 50% overall, and
– Satisfactory progress: at least 40% in
Project 1 and the test combined, and
– At least 40% in the final exam
• Students who fail to make satisfactory progress
will be notified in writing by the end of Week 10
and will be excluded from the final exam
Everyone in CITS1401 is capable of passing, but history
suggests that 20% of you will fail – who do you want to be?
