What is important from the instruction? Using the questions, pupils and teachers see how the AP® Computer Science exam addresses topics. Scholars realize the importance of the case studies from the course. The released questions range...

Scratch the surface of computer coding. A seven-unit lesson guide provides a crash course on computer programming. It uses a programming language called Scratch.

That's one complicated address book! To understand the need for a system that keeps track of addresses, pupils trying to find the IP address of their classmates. Then individuals change their IP addresses, which leads to research...

Color me green. The fourth lesson in a unit of 15 introduces the class to color images and how to encode color images using binary code and hexadecimal numbers — and they will quickly notice that it is easier to code the...

Four free-response questions from the 2005 AP® Computer Science exam show pupils how topics appear on the test. Scholars use the questions to practice coding skills in preparation, while teachers use the items to determine what concepts...

Coding works for other fields. The free-response questions for AP Computer science require pupils to develop code to solve a problem. Problems range from creating a histogram to developing an encryption program. Teachers use the...

Stay tuned for a programming announcement. The resource contains the four free-response questions from the 2007 AP® Computer Science exam. Teachers and pupils use the questions to understand how topics appear on exams. The items cover...

You deserve a C++. Released items from the last year of C++ programming for the AP Computer science course provides opportunities to practice. Pupils use the questions to develop their programming skills by finding solutions to the...

Let the resource quench your thirst for knowledge, like a vending machine that dispenses drinks. Future computer scientists develop an algorithm to identify the fewest number of coins that a vending machine could use in creating change....

Speaking of the Internet. The culminating lesson for the unit on the Internet challenges pupils to prepare short, two-minute speeches on an issue facing society. The pupils chose from three topics that connect the Internet and...

Data, data everywhere. Challenge your class to begin thinking about data, the ways people collect information, and what we can learn from this data. Class members discuss sources of data and then individuals answer questions in the...

Imagine drawing with zeros and ones. The third lesson in a unit of 15 introduces the class to creating black and white images. Pairs get together to create an encoding scheme in order to make these images. They move on to a...

Introduce your class to the layers of abstraction of the Internet with a lesson on the HTTP protocol. Pupils review previous lessons on levels of the Internet, then investigate new high levels by examining the HTTP traffic on...

This optional lesson introduces the class to the idea of a minimum spanning tree. The activity focuses on determining an algorithm that will find the most efficient path in a network to transfer data. 

Encoding What I did Last Summer. Class members develop a way to encode a personal experience using a top-down approach to determine components and sub-components of their experience They then pick one portion of the experience and go...

I'm compressed. Groups do a rapid research of different file types to determine what kind of compression the formats use and how it works. They share their information with the rest of the class until everyone has all the information for...

The second lesson in a unit of 15 introduces pupils to text compression. The class begins with discussing how they already use text compression when sending text messages. Pairs learn more about the subject as they work to compress a...

A bite of bits. The first lesson plan in a unit of 15 introduces the class to the byte. Pupils learn about other standard units for measuring file sizes, develop an understanding of relative sizes and the kind of units used to...

Young programmers investigate the Single Source Shortest Path problem by working in paris to devise their own algorithm. They then progress to using Dijkstra's Algorithm to solve the problem. 

Imagine computer science all summed up in one book. This resource provides 16 chapters that cover many aspects of computer science, ranging from algorithms to software engineering. The e-book contains links to applets to help explain...

Your routers don't seem to be routing correctly. To figure out why, pupils act like routers, talk to their direct connects in order to determine as much information about the simulated network as possible. As they learn more about...

What's the least number of colors needed to color a U.S. map? The lesson begins by having pupils view a video clip on continuous and discrete phenomenon, then launches into an activity reminiscent of Zeno's paradox. A separate video...

Students create a bar graph on the computer using given information from the teacher. They create a bar graph using their own information chart (they need to create one on separate paper first). They utilize Microsoft Excel for this...
