AP Computer Science Principles: Cybersecurity

Units

Unit Description
Introduction to Programming: Karel is a dog that only knows how to move, turn left, and place tennis balls in his world. You can give Karel these commands to instruct him to do certain things. We use Karel to show you what it means to program, and allow you to focus on problem-solving.
Practice PT: Pair-Programming Paint!: Karel is a dog that only knows how to move, turn left, and place tennis balls in his world. You can give Karel these commands to instruct him to do certain things. We use Karel to show you what it means to program, and allow you to focus on problem-solving.
Programming with JavaScript: Students learn the basics of JavaScript, including variables, user input, control structures, functions with parameters and return values, and basic graphics, how to send messages to objects.
JavaScript Control Structures: Students learn how to use booleans and logical operators with control structures to make more advanced programs in JavaScript.
Functions and Parameters: Students learn how to write reusable code with functions and parameters.
Practice PT: Tell a Story: Students apply what they've learned from the previous module to write reusable code with functions and parameters.
Basic Data Structures: Students learn about lists and arrays which are essential basic data structures that any program will use.
Digital Information: Students learn about the various ways to represent information digitally including number systems, encoding data, programmatically creating pixel images, comparing data encodings, compressing and encrypting data.
Practice PT: Steganography - Color Channels: In this project, students will be implementing a form of cryptography known as Steganography.
Encryption: In this unit, students will learn about the various ways we encrypt information. Topics covered include encoding and decrypting Caesar and Vigenere ciphers, and understanding symmetric and public key encryption
Practice PT: Create an Image Filter!: In this project, students pair up with a partner to develop a novel image filter that can be applied to any digital image of their choosing.
The Internet: Students explore the structure and design of the internet, and how this design affects the reliability of network communication, the security of data, and personal privacy.
Cybersecurity: In this unit, students will learn about assessing different cybersecurity risks on both a personal level and a wider network level.
Project: Cyber Ethics: In this project, students will choose one of four articles on cyberethics and write a position paper. Based on that article, they will provide an arguable opinion about who is responsible and why.
Data: Students explore using computational tools to store massive amounts of data, manipulate and visualize data, find patterns in data, and pull conclusions from data.
Project: Present a Data-Driven Insight: Students explore using computational tools to store massive amounts of data, manipulate and visualize data, find patterns in data, and pull conclusions from data.
Project: The Impacts of Computing: While the performance task is no longer a graded part of the AP test, the skills needed for the performance task are still a part of the curriculum. This module will give students a chance to apply these concepts in a project format.
Create Performance Task:
AP Exam Review: Students review of the topics covered in the course and practice solving AP Exam style multiple choice questions.
Creative Development: This unit introduces students to the theory and practice of user interface design. Students learn about what makes an engaging and accessible user interface, and will employ an iterative design process including rapid prototyping and user testing to design and develop their own engaging web pages.
Final: Final exam for the course.

Unit Description
Midterm: The midterm for the course.
Extra Karel Practice: It can take some time to learn all of Karel's tricks. Brush up here with some extra Karel practice problems. These reinforce all of the fundamental concepts introduced in Karel, including commands, functions, loops, conditions control structures, and problem decomposition.
Extra Karel Puzzles: A set of all the trickiest Karel puzzles for you to solve
Karel Challenges: In this module you'll take all the foundational concepts from Karel to solve some programming challenges.
Web Development: In this unit, students will go through a high level introduction to HTML, CSS, and the processes involved in viewing web pages on the internet. Students will create several simple web pages using the CodeHS online editor to gain practice using the various features of HTML and CSS.
Functions and Parameters Practice: Functions are the critical building block of any program. To be able to use functions, you want to make sure you fully understand parameters, return values, and how to create your own functions. That is what this practice module is for.
Extra Console Challenges: A bunch of fun console programs to get practice with JavaScript.
Animation and Games: Now, your graphics will come to life. You will learn how to make objects move around the screen. You will also learn how to let the user interact with your program with the mouse. At the end of this section, you will program your very own video game.
Project: Breakout: Learn to make the game invented by Steve Jobs and Steve Wozniak! In this module, you will build your very own breakout game from scratch using JavaScript.
Practice PT: Steganography - Binary: In this unit, students will learn about the various ways we represent information digitally. Topics covered include number systems, encoding data, programmatically creating pixel images, comparing data encodings, compressing and encrypting data.
Practice PT: The Effects of the Internet: This unit explores the structure and design of the internet, and how this design affects the reliability of network communication, the security of data, and personal privacy.
Visualizing Music: Learn how to create your own music visualizer!
Project: Tic Tac Toe: Did you know that Tic Tac Toe may have been played in Ancient Egypt? Now, you get to make your own game of tic tac toe on the computer! In this module, you will take what you have learned about data structures and make a two player tic tac toe game.
Project: Helicopter Game: You now have the tools to make amazing games. This module walks you through the creation of the classic Helicopter game one step at a time.
Data Structures Challenge Problems: Learn to code Conway's Game of Life and your own Connect Four game using your skills in data structures.
More Basic Data Structures: We introduce more data structures: sets, objects, and grids. These are the essential basic data structures that any program will use.
