Week’s Agenda:
Continuation to UNIT 2: Digital
Information:
This
unit further explores the ways that digital information is encoded, represented
and manipulated. Being able to digitally manipulate data, visualize it, and
identify patterns, trends and possible meanings are important practical skills
that computer scientists do every day. Understanding where data comes from,
having intuitions about what could be learned or extracted from it, and being
able to use computational tools to manipulate data and communicate about it are
the primary skills addressed in the unit.
Chapter
1: Encoding and Compressing Complex Information
Big Questions
·
Are the ways in which digital information
is encoded more laws of nature or man made?
·
What kinds of limitations does the binary
encoding of information impose on what can be represented inside a computer?
·
How accurately can human experience and
perception be captured or reflected in digital information?
Enduring Understandings
·
1.1 Creative development can be an
essential process for creating computational artifacts.
·
1.3 Computing can extend traditional forms
of human expression and experience.
·
2.1 A variety of abstractions built upon
binary sequences can be used to represent all digital data.
·
3.3 There are trade offs when representing
information as digital data.
Vocabulary
- Heuristic -
a problem solving approach (algorithm) to find a satisfactory solution where
finding an optimal or exact solution is impractical or impossible.
- Lossless
Compression -
a data compression algorithm that allows the original data to be perfectly
reconstructed from the compressed data.
- Image -
A type of data used for graphics or pictures.
- metadata -
is data that describes other data. For example, a digital image my include
metadata that describe the size of the image, number of colors, or
resolution.
- pixel -
short for "picture element" it is the fundamental unit of a
digital image, typically a tiny square or dot which contains a single point
of color of a larger image.
- RGB -
the RGB color model uses varying intensities of (R)ed, (G)reen, and (B)lue
light are added together in to reproduce a broad array of colors.
- Lossy
Compression -
(or irreversible compression) a data compression method that uses inexact
approximations, discarding some data to represent the content. Most commonly
seen in image formats like .jpg.
- Abstraction - Pulling out specific differences to make one solution
work for multiple problems.
- Hypothesis - A
proposed explanation for some phenomenon used as the basis for further
investigation.

order to prepare you for your two AP CSP college-board performance tasks we need
to get use to reflecting on our daily work and experiences. This is a skill that
will prove to be useful when you go on to college, enter the workforce, and even
in every aspect of your everyday life. Every
day at the end of class you should save your work, open up your journal, put
down today’s date, and provide the following information.
1. Provide at least on new thing that you learned today – Refer to today’s Objectives
2. What did you accomplish today?
3. Indicate any problems or obstacles you experienced
4. How did you solve the problems or obstacles that you experienced?
Feel
free to provide screen shots of your daily work in order to illustrate your
day’s activities. Windows provides a Snipping
Tool within its provided Accessories that may be used for this purpose.

Setting up the APP
Inventor and Emulator for Testing
Setting
Up App Inventor 2
You can set up App Inventor and start building apps in minutes.
The Designer and Blocks Editor now run completely in the browser (aka
the cloud). To see your app on a device while you build it (also called
"Live Testing"), you'll need to follow the steps below.
You
have three options for setting up live testing while you build apps
If you are using an Android device and you have
a wireless internet connection, you can
start building apps without downloading any software to your computer. You will
need to install the App Inventor Companion App for your device. Choose Option
One below. This
option is STRONGLY RECOMMENDED
For Class Use this Option: If you do not have an Android
device,
you'll need to install software on your computer so that you can use the
on-screen Android emulator. Choose Option Two below.
If you do not have a wireless internet
connection, you'll need to install software on your computer so that you
can connect to your Android device over USB. Choose Option
Three below. The
USB Connection option can be tricky, especially on Windows. Use this as a last
resort.
Option One - RECOMMENDED
Build apps with an Android device and WiFi Connection (preferred): Instructions
If you have
a computer, an Android device, and a WiFi connection, this is the easiest way to
test your apps.
********* Option Two – use these instructions
for class! **********
Don’t have an Android device? Use the
Emulator: Instructions
If you don’t have an Android phone or tablet handy, you can
still use App Inventor. Have a class of 30 students? Have them work primarily on
emulators and share a few devices.
Option Three
No WiFi? Build apps with an Android device and USB Cable: Instructions
Some
firewalls within schools and organizations disallow the type of WiFi connection
required. If WiFi doesn’t work for you, try USB.
System requirements
Note: Internet Explorer is not supported. We recommend Chrome or Firefox.
1)Setup
your emulator by following these Instructions
2)Check out the Designer and Blocks Editor Overview
Designer
and Blocks Editor Overview: Gives
a tour of the App Inventor environment.
3)
Setup Review the
following Beginner Tutorials
Beginner
Tutorials: Highly
recommended as the best way to get started programming in App Inventor.
