Lesson 1 - CSE

An iterative and incremental development process used by a team of developers to create a product that benefits from input from multiple stakeholders.

A set of program instructions. Strings of commands that tell the computer how to respond to inputs and how to produce output.

Information or signals entered into a computer system. Examples are buttons, keys on a keyboard, touch screens, and accelerometers.

Information or signals produced or delivered by a computer system.

A means to create computer programs by manipulating elements graphically rather than using text. Also called visual programming language.

The set of rules that defines the combinations of symbols that are considered to be correctly structured in that language. The grammar and spelling of text-based programming languages.

A technique or process that manages complexity in a program or computer system. “Hides” details or removes duplication, allowing the programmer to focus on high-level considerations and functions rather than the rules of a programming language.

A function of an application or user interface.

The individual items that make up the whole solution that will benefit the user. It is addressed individually in a prioritized manner during app creation.

Considering what is important to who's using the software.

The visual platform that a user interacts with, which then sends a message to the operating system for what to do next.

Where you can create the user interface and add common features you want into the app

Where you can program the features you added in designer view

A function or artifact in an app that you can add in Design view of MIT App Inventor. Examples are: Canvas, Camera, Label, Slider, Sound, Horizontal arrangement, Button.

In MIT App Inventor, a control block that looks for inputs or events to know when to perform a specific action.
