What is a reason to include comments in a program?

Comments tell the programmer what the code is doing.

Comments tell the computer what the code is doing.

Comments help the user work an app more effectively.

Comments will show up in the console so when the program is run, the programmer know what happens.

Statements that should only run upon a specific user action should be placed

within an onEvent programming statement

after the first programming statement

When the user hovers their mouse over the hawk, the

The sparrow will be confined to the lower right and the hawk to the upper left

both birds will appear only in the middle of the screen

The sparrow will be confined to the upper right and the hawk to the upper left

The sparrow will be confined to the lower left and the hawk to the upper right

Choose all the correct options. When debugging, you should

add some console.log statements to see what is going on

describe your program and the odd behavior to a friend

reduce the amount of code and see if the behavior improves

run the program over and over, staring really hard at it

What is the definition of an input?

Data that are sent to a computer for processing by a program. Can come in a variety of forms, such as tactile interaction, audio, visuals, or text.

Any data that are sent from a program to a device. Can come in a variety of forms, such as tactile interaction, audio, visuals, or text.

What is the definition of an output?

Any data that are sent from a program to a device. Can come in a variety of forms, such as tactile interaction, audio, visuals, or text.

Data that are sent to a computer for processing by a program. Can come in a variety of forms, such as tactile interaction, audio, visuals, or text.

What is the definition of event-driven programming?

Program statements that run when triggered by an event such as a mouse click or key press.

Program statements run in order, from top to bottom.

What is the definition of sequential programming?

Program statements run in order, from top to bottom.

Program statements that run when triggered by an event such as a mouse click or key press.

What is the definition of documentation for code?

A written description of how a command or piece of code works or was developed.

Lines written into a program to be read by people and does not affect how the program runs.

The code for a specific program, such as the code for an app.

What is a syntax error?

A mistake in the program where the rules of the programming language is not followed.

A mistake in the selection of an ID for event-driven programming.

A mistake in the binary code of a program.

Which of the following is TRUE regarding what you see in this image?

randomNumber is needed to make this app more challenging in the hawk and sparrow jumping all over the screen

A sound will play based on Lines 15 and 16

The event will trigger if the sparrow is clicked on with the mouse

A playSound command cannot go into an onEvent and therefore, the sound will not play here

Which of the below is NOT a recommended approach to designing an app?

Coding up the entire app before testing

Coding and testing small chunks in iterations

About

This quiz focuses on introductory app design concepts within the context of AP Computer Science Principles, targeting high school students in grades 9-12. The content centers on fundamental programming concepts including event-driven programming, sequential programming, debugging, and the software development process. Students need to understand how user interactions trigger events in programs, trace through code execution to predict console outputs and visual changes, distinguish between different programming paradigms, and apply debugging strategies. The questions assess students' ability to analyze code snippets, predict program behavior, identify syntax errors, and comprehend key terminology such as algorithms, commands, bugs, inputs, and outputs. Students must also demonstrate understanding of the software development lifecycle phases and the importance of user testing and documentation in creating effective applications. Created by S. Wines, a Computers teacher in US who teaches grade 9-12. This comprehensive assessment supports instruction by providing multiple opportunities for students to demonstrate their understanding of core app design principles through varied question formats including code tracing, definition matching, and conceptual analysis. The quiz functions effectively as a unit review or formative assessment tool, allowing teachers to gauge student comprehension before moving to more advanced programming topics. It can be implemented as a pre-test to identify knowledge gaps, used during instruction for guided practice, or assigned as homework to reinforce classroom learning. The content aligns with AP Computer Science Principles standards, particularly those addressing algorithms and programming (AAP), computing systems (CSN), and the impact of computing (IOC), while building foundational skills essential for success in advanced computer science coursework.
