Introductions
While technology can and does bless lives, “never forget that while we have computers, cameras, microphones, fiber-optic networks, clouds, and satellites, we have failed if we do not rely on the Holy Ghost.”
- President Henry B. Eyring
Today
• Labs, Homework and Quizzes• Grading• Calendar and due dates• What you will need to get started• Class format• Policies• Learning Objectives and Outcomes• Groups• A Problem
I Remember:
10% of what I read,
20% of what I hear,
30% of what I see,
50% of what I see and hear, +
70% of what I discuss with others,
80% of what I experience by doing,
95% of what I teach others.
Therefore, CS100 will be …
• Hands-on, lab assignments – learn by doing
• Interactive in class (some work in groups)
• Thinking assignments
• Homework, quizzes, analyzing, sharing in class
Labs: 70% of Grade
• Lab 1: Introduction to Computer Lab - 1 %
• Lab 2: Personal Website - 3%
• Lab 3: HTML Order Form - 4%
• Lab 4: Javascript Graphics - 5%
• Lab 5: HTML Order Form with JavaScript - 10%
• Lab 6: Image Editing with Photoshop or GIMP - 10%
• Lab 7: Editing Sound with Audition or Audacity - 8%
• Lab 8: Movie Editing with Premiere, iMovie etc. - 9%
• Lab 9: Family History I - 10%
• Lab 10: Family History II - 10%
Lab Pass-Offs
• Lab assignments can be found on the CS100 website http://students.cs.byu.edu/~cs100ta/
– Completed Lab assignments with a 'Date Modified' timestamp on or before the due date receive full credit.
– Any lab assignment completed after the due date will automatically lose 1 point (10% of its value) per school day. (After 2 weeks, an assignment has no grading value!).
– Lab assignments are 'passed off' by a TA during regular TA hours in 1121 TMCB or 1150 TMCB.
Late Policy
• All assignments due on date posted – “Date Modified” timestamp.
• Any assignment submitted after that loses 10% per school day.
• After 2 weeks the assignment has no value.
Cheating
• Talk to anyone you want about how to do the assignment
• Work with your assigned group• We will make it clear which assignments
should be done with your group and which you should do the work yourself
• Copying or having someone else do the work is considered cheating and a violation of the University Honor Code
Pornography
• Zero Tolerance
• “Crash and Tell”
Homework: 15% of Grade
• 8 Homework assignments
• Paper and pencil and/or keyboard
• Assigned and reviewed in class
• Due on the date indicated on the Calendar
• To help develop algorithmic thinking and problem-solving skills
• Will be able to drop 1 (lowest) homework score
Quizzes: 15% of Grad
• 7 Quizzes• Multiple Choice, Closed Book, Work alone• Given on Canvas – review in class• Will need to be completed by midnight on the
due date.• Keep students current with new concepts• No re-takes or make-ups on quizzes unless prior
arrangements are made (or sickness and extenuating circumstances)
• Will be able to drop 1 (lowest) quiz
Your Grade:
• Lab Assignments: 70%
• Homework: 15%
• Quizzes: 15%
= 100%
No Exams! No Final! And that’s final!
The Lab Assignments are cumulative,
as are Homework Assignments and Quizzes.
Schedule: See Web Page

Questions about what you need to get started?
Class Structure/Format
Class Format: Highly InteractivePrayer/thought
Questions from HW, Quizzes, Life; Peek at new technologies
1. Introduce: Topic/Problem/Question
2. Explain: concepts/principles, tools needed to solve problem
3. Demo: use of the tools, software
Students follow interactively on keyboard
4. Practice: Give a specific task/problem to solve
- the one posed at the beginning
- Some tasks groups, some solo
5. Evaluate: Walk around: help, discuss problem/solution.
Share: Project examples of student work on screen
6. Re-practice: In class, Homework, Labs
Lecture Material
• You will be responsible for the Lecture Material on your own, outside of class,in groups.
• Lecture Material will appear on Quizzes
• We will use the first few minutes of class to hitthe highlights and answer any questions you have
Laptop in-Class Policy
• Use while we are doing interactive demostogether or while working on an in-classexercise/problem or sharing work
• Laptop lids are down otherwise!Please no emailing or working on assignments during discussion/lecture.It is too distracting to other students.
