Essential Concepts in Computer Science

In computer science, understanding problems and systems can be difficult and time consuming. In this book, readers will learn about decomposition, a technique used to break down computer problems and systems into parts that are easier to understand and work with. STEM topics from the Next Generation Science Standards are discussed throughout this informative text. Students will be surprised to learn they actually decompose problems in their daily lives without even realizing it.

Computers and other types of technology have changed our lives in ways never imagined. Today, we constantly have a wealth of information at our fingertips. Computers help us work better and faster. Readers will learn about the many positive impacts of computers in society. They'll also read about the many negative impacts, such as threats to our privacy and security and a potential decrease in physical activity. Students will be encouraged to think about the role technology plays in their everyday lives.

Computers are playing a larger role in our lives every day, which means the teams behind these devices are becoming more and more important. In this book, students receive an inside look at the collaboration that goes into developing the technology that powers our lives. Readers will learn about the different teams that tackle each step of a computer science project, from programmers and software engineers to testers and debuggers. STEM concepts from the Next Generation Science Standards are covered. Fact boxes and sidebars provide additional opportunities for students to learn about collaboration in computer science.

Think about your favorite computer program or smartphone app. Do you know how it was made? In this book, readers will learn about the work that goes into creating the software we use every day. Exciting fact boxes and sidebars add depth to the text with additional information about the software design process. Readers will gain an understanding of the various steps of the software development life cycle. They'll also be introduced to famous software architects and STEM concepts from the Next Generation Science Standards throughout the text.

Algorithms might sound like a complicated tech term, but don't be intimidated, people actually use them every day. Using accessible language and full-color photographs, this book simplifies algorithms in an easy-to-understand way. Readers will be amazed to learn that an algorithm is just a set of steps for computers to follow to get things done. STEM topics from the Next Generation Science Standards are emphasized throughout the text. Sidebars featuring key terms help readers grow their tech vocabulary, and fact boxes provide additional opportunities to learn.

In computer science, an algorithm is a plan for solving a problem. One of the simplest ways to write out an algorithm is by using pseudocode. Pseudocode might sound complex, but readers will be surprised to learn it's just the process of writing out the steps of an algorithm in plain English. Readers are introduced to STEM concepts from the Next Generation Science Standards as well as common pseudocode vocabulary. Accessible language and informational sidebars and fact boxes allow students to learn about this important computer science topic in a variety of ways.
