Why an app?

Completing a small amount of code at a time and testing it as you go is called

• Working Slowly

• Incremental Design

• Coding Steps

• The Design Process

UI stands for

• User Interface

• User Initiated

• Use Increments

• Unlimited Interfaces

Choose all the correct statements. The UI is

• What the User sees on the tablet

• The code interactions

• The view layer

• How the user interacts with a program

The view layer is the part of the app

• that contains the code

• that collects data

• that the user sees

The controller layer is the part of the app

• The user sees

• That contains the code

• That collects data

Clicking a button is an example of

• An event

• A block

• A condition

• An unexpected action

In App Inventor, events are programmed using

• event handlers

• the user interface

• the view layer

• the tablet

An event handler

• performs a set of instructions when a certain event happens

• schedules concerts

• runs a program when an app starts

• performs a set of dance moves

A User Event is triggered by

• An interaction with UI

• Situations that upset the user

• Dropping your tablet

• Only by clicking a button

True or False: All events for a program are in the same algorithm

• True

• False
