CS1315: Introduction to Media Computation

CS1315Introduction to Media Computation

• Introduction to Course
• Administrivia

2
Caveats

• This is not an easier course than CS1321
• Its a different course
• In particular, you WILL still be asked to learn
  to program!
• You will not have fulfilled the pre-requisite for
  CS1322 by taking this class
• But CS1316 (Representations of Structure and
  Behavior) will be offered next Spring, and that
  fulfills the pre-req for CS1322

3
History and Purpose of Course

• Created in response to attitudes about CS1321,
  and CS1, nationally
• Goal is to teach computation in terms relevant to
  non-CS and non-ECE majors
• Inspired in part by ECEs DSP First
• Developed with an advisory board from across
  campus LCC, Applied Physiology, Math, ECE, CETL

4
Course Objectives

• Students will be able to read, understand,
  modify, and assemble from pieces programs that
  achieve useful communication tasks Image
  manipulation, sound synthesis and editing, text
  (e.g., HTML) creation and manipulation, and
  digital video effects.
• We will always give you examples to use when we
  ask you to program
• Students will learn what computer science is
  about, especially data representations,
  algorithms, encodings, forms of programming.
• Students will learn useful computing skills,
  including graphing and database concepts

How grades will be determined

• Pre-quizzes and quizzes - four (50)
• Pre-quizzes are worth 20 points, quizzes 80
• Homework - four (20)
• One final (30)
• OVERALL Grades are straight scale 90-100 A,
  80-89 B, 70-79 C, 60-69 D, 59 or below F

Lablets (We won't do these!)

• How to use your computer to do useful things
• Word, Excel, PowerPoint, HTML
• On your own computer (not in a lab)
• Collaborative

9
Pre-quizzes and quizzes

• Pre-quizzes are collaborative Work on them with
  your friends to learn the material
• Quizzes will be very similar in content, but on
  Thursdays.

10
Homework

• Programming assignments
• Designed to take no more than a couple hours each
• Collaborative
• No Late Assignments Accepted AT ALL
• Assignments due Friday

Text

• Book from PearsonIntroduction to Media
  ComputationA Multimedia Cookbook in Python
• CD with software and media attached to book
• JES (our programming environment) also on CoWeb

13
No Cell Phones or Pagers Permitted

• Emergencies happen
• Let me know before class if you are expecting a
  phone or page and need to leave it on
• But in any event, if you get a call or page, you

• If youre not here, you will not see the
  demonstrations
• Class absences will count against you. Three
  strikes and you're out!

15
Organization of the class

• Mandatory lectures Monday, Wednesday and Friday
  in large lecture hall format
• Mandatory recitation Tuesday
