Today, we're going to talk about how the Internet works. Specifically, how that stream of characters you punch into your browser's address bar, like "youtube.com", return this very website. Just to clarify we're talking in a broader sense about that massive network of networks connecting millions of computers together, not just the World Wide Web, which is a portion of the Internet, and our topic for next week. Today, we're going to focus on how data is passed back and forth - how a domain name is registered by the Domain Name System, and of course how the data requested or sent gets to the right person in little packets following standard Internet Protocol, or IP. We'll also discuss two different approaches to transferring this data: Transmission Control Protocol, or TCP, when we need to be certain no information is lost, and User Datagram Protocol, or UDP, for those time sensitive applications - because nobody wants an email with missing text, but they also don't want to get lag-fragged in their favorite first person shooter.

Developed by the NYCDOE CS education team, the Introduction to Computational Media is a yearlong (108 hours) creative computing course for high schools using the open source Javascript library p5.js. By understanding how code can be a medium for creative expression, students will learn the fundamentals of computer science while designing and prototyping interactive projects that run on a browser. Additionally, students will learn how HTML/CSS elements can interact with p5.js to fully take advantage of developing content for a browser. This course has been implemented in NYC schools via CS4All’s Software Engineering Program (SEP), revised by classroom teachers with guidance from the Processing Foundation, and aligns with the CS4All Blueprint for CS education that emphasizes a hands-on CS approach called creative computing.

Developed by the NYCDOE CS education team, the Introduction to Physical Computing course is a 54-hour long introductory computer science course that guides students to explore fundamental CS concepts through tinkering with the micro:bit, a simple programmable computer device. Each unit of the course guides students through the learning process with three practices: analyzing computer applications around them based on a given issue; prototyping a project that reflects the result of the analysis plus their interest; and communicating about their projects, including the functionality of a project, a project development process, influence from other projects and their contribution to a project when working in a group. The curriculum and support sessions assist educators in discovering the most effective way of facilitating this course for their own classroom, while helping them to become comfortable with the main tool, the micro:bit.

Algorithms are the sets of steps necessary to complete computation - they are at the heart of what our devices actually do. And this isn’t a new concept. Since the development of math itself algorithms have been needed to help us complete tasks more efficiently, but today we’re going to take a look a couple modern computing problems like sorting and graph search, and show how we’ve made them more efficient so you can more easily find cheap airfare or map directions to Winterfell... or like a restaurant or something.

SFUSD's creative computing curriculum introduces computer science as a creative, collaborative, and engaging discipline to children in kindergarten through second grade.
Across 4 units and 15-20 lessons, students will learn about algorithms and programming, computing systems, the Internet, and impacts of computing, while developing strong practices and dispositions. Lessons are designed to be implemented in 45 to 60-minute periods approximately once per week.
There are three levels available and a flow chart to help you decide where your students should start!
Just because students are young doesn't mean they can't code! Get them started today.

Today, we are going to start our discussion on user experience. We've talked a lot in this series about how computers move data around within the computer, but not so much about our role in the process. So today, we're going to look at our earliest form of interaction through keyboards. We'll talk about how the keyboard got its qwerty layout, and then we'll track its evolution in electronic typewriters, and eventually terminals with screens. We are going to focus specifically on text interaction through command line interfaces, and next week we'll take a look at graphics.

Next Generation Learning is a government campaign initiated by Becta. We aim to use technology to create a more exciting, rewarding and successful experience for learners of all ages and abilities. This enables everyone to achieve their potential and achieve much more. The facts speak for themselves:
• 85% of secondary school learners believe that technology makes it easier to do homework. • 85% of primary school learners believe that technology makes learning more interesting.
All of this is likely to mean improved GCSE grades and more children moving into higher education. Despite this, only one in four schools is currently using technology to its full potential. Help us to change that by Getting Involved.
This site contains lots of useful information about how technology is used in the classroom, and for studying at home and how to learn safely online.

The Little Book of Semaphores is a free (in both senses of …
The Little Book of Semaphores is a free (in both senses of the word) textbook that introduces the principles of synchronization for concurrent programming.In most computer science curricula, synchronization is a module in an Operating Systems class. OS textbooks present a standard set of problems with a standard set of solutions, but most students don't get a good understanding of the material or the ability to solve similar problems.The approach of this book is to identify patterns that are useful for a variety of synchronization problems and then show how they can be assembled into solutions. After each problem, the book offers a hint before showing a solution, giving students a better chance of discovering solutions on their own.The book covers the classical problems, including "Readers-writers," "Producer-consumer", and "Dining Philosophers." In addition, it collects a number of not-so-classical problems, some written by the author and some by other teachers and textbook writers. Readers are invited to create and submit new problems.
