Intro to Computer Science in Python 3


Unit Description
Welcome: Students gain an understanding of what the course is about and reflect on what they hope to learn.
Introduction to Programming with Turtle Graphics: Students learn Python commands, functions, and control structures by drawing shapes on their screen and solving puzzles with Turtle Graphics.
Basic Python and Console Interaction: Students learn the basics of programming by writing programs that interact with users through the keyboard.
Conditionals: Students teach their programs to make decisions based on the information it receives.
Looping: Students learn how to write more efficient code by using loops as shortcuts.
Functions and Exceptions: Students learn how their programs can be decomposed into smaller pieces that work together to solve a problem.
Strings: Students use more sophisticated strategies for manipulating text in their programs - slicing, concatenating, and formatting.
Creating and Altering Data Structures: Students learn how tuples and lists are formed and the various methods that can alter them.
Extending Data Structures: Students learn to build more complex programs that make use of grids and dictionaries.
Project: Guess the Word: Students use the skills they've learned throughout the course to build a word guessing game.
Final Exam: Students prove their knowledge of content learned throughout the course through a multiple choice, short answer, and programming exam.

Unit Description
Classes and Objects: Learn the principles of object-oriented design.
Advanced Tracy Challenges:
Additional Topics: Teach your program to make decisions based on the information it receives. Learn how to decompose your program into smaller pieces that work together to solve a problem!
Project: Who Said It?: Use your programming knowledge to build a program that can predict whether a small sample of text was written by Jane Austen or William Shakespeare!
Python Graphics (Tkinter):
Project: Mastermind:
Categorizing Triangles: Explore how we can use a computer to perform calculations and make decisions based on user input! You will use Turtle Graphics in Python to draw a triangle and write text to the screen and then use if/else statements, variables, functions, and mathematical, logical, and comparison operators to print the resulting triangle category.
Python Graphics (Brython):
Karel in Python: 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.
