Big Idea 1: Creative Development

• What do computing innovations HAVE TO INCLUDE as part of its functionality? a computer program
• anything created by a person using a computer: computer artifacts
• Key steps for successful project development: investigate, design, prototype, test, reflection
• investigating the problem or idea to fully understand it, defining WHAT the project needs to solve: investigation
• this phase involves taking the requirement identified and creating some form and functionality around them, determines HOW the requirements will be met: design
• all of the interactions both into and out from each step that people will see and use are considered the: user interface
• When do you come up with a testing strategy? design phase
• a mockup of the user interface screen to give users a starting point for suggestions: prototyping
• this relies on an event to occur to trigger code to run: event-driven programming
• the best way to find a logic error: handtracing (debugging)
• what does IDE stand for?

  integrated development environments
• these show the code structure and each line that executes to help track where errors are occuring: IDE
• these errors occur when the program can still run, but produces unexpected results: logic error
• these errors occur in computers when an integer is larger than the programming language can hold: overflow error
• 2 types of development processes

  iterative, incremental
• In this developmental process, steps are repeated several times throughout the project. Each step produces a better result: iterative
• In this developmental process, the pieces of the program are broken down into smaller sections. The overall software system is built piece by piece until completed: incremental
• This is the "guide" to how the program is designed to work: Program documentation
• Why should boundary values be tested? To ensure the program doesn't include too few or too many elements
• describes how a program runs during execution and how anyone using it interacts with it: program behavior
• Finger swipes or taps, a message coming through via text, a mouse click, or a timing event are all examples of?

  event-driven programming
