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.”

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 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

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

Prayer/thought
Questions from HW, Quizzes, Life; Peek at new technologies
Introduce: Topic/Problem/Question
Explain: concepts/principles, tools needed to solve problem
Demo: use of the tools, software
Students follow interactively on keyboard
Practice: Give a specific task/problem to solve
- the one posed at the beginning
- Some tasks groups, some solo
Evaluate: Walk around: help, discuss problem/solution.
Share: Project examples of student work on screen
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 hit
the highlights and answer any questions you have
Laptop in-Class Policy
• Use while we are doing interactive demos
together or while working on an in-class
exercise/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.
