Computer Science - 1
 Beginning
programming using C++
– Not C++ course, minimal C++ gadgets
– Not a great deal of OOP
– Same basic course I have taught in Pascal & Algolw.
 Straight
C++, but will be operating within visual
studio in class.
– Software available for free (Visual Studio)
– You can use another complier, but you are on your
own.

Grading and Assignments
 Everything
listed on the course web page
 Turn in code using Moodle
– As .txt file.
– Structure charts as file (scanned, word, etc)
 Weighting:
– 50% homework, 50% tests, but must pass tests.
 Cheating:
 Ok
to get some help, but…..

My Approach
 How
should I teach creative problem solving
which is the essence of programming?
 How would I teach you to compose music?
– Scales, how to read music, lots of examples of good
music (Bach, Corelli, Hendrix, etc), but
– Eventually you have to create new music, turn it in,
I shred it, and you re do it over and over again till it
starts being acceptable.
– Thus, this is a course on composing code.

Demanding Course
 Start
Early
– Most bugs are found in the shower the next morning
– You need time to stop by my office and ask questions.
 Work
–
–
–
–
–
Carefully!
Make haste slowly
A stitch in time saves nine
Measure twice, cut once
The fastest way to fix a bug is not to make it

You often necessarily will
be on your own
I
cannot tell you how to solve the assignment
without risking your doing worse on the final.
 Often a bit frustrating, but very rewarding when
you finish. Therefore:
–
–
–
–
–
Don’t give up
When stuck, print out a hardcopy and take a walk
Bugs are found in the shower the next morning
Avoid “the fear of starting”
Start early

Context Switching
 Context
switching is essential to creative
problem solving:
 How
do you get down off an Elephant?
 You don’t, you get down off a duck!

Context Switching
 Learn
how to think “out of the box”
– Free association, rapid context switching:
 Psychologists
call this “changing prospective”
 Essential problem solving skill
 This
is a course on problem solving, not just coding
 Lectures often move to topics that may at first
glance not seem related to coding
– The more you can follow, keep up, and begin to do this
yourself, the better your problem solving skills.
