oneteachersview: July 2015
http://oneteachersview.blogspot.com/2015_07_01_archive.html
This is one teachers view of what is happening in his school at the moment, and what is happening in his teaching. Sunday, 26 July 2015. This weekend I spent time at #educampAKL. Getting to see many teachers that I have twitter conversations with regularly, however having the Face to Face is important as well. Tamaki College provided an excellent backdrop to these conversations with their classrooms providing a modern learning environment to learn in. Second (and third), the Hobsonville Point area and ev...

oneteachersview: Google NZ CS Partnership Summit
http://oneteachersview.blogspot.com/2015/07/google-nz-cs-partnership-summit.html
This is one teachers view of what is happening in his school at the moment, and what is happening in his teaching. Wednesday, 8 July 2015. Google NZ CS Partnership Summit. To help illustrate some of these to help people see the development of the resource. Moving onto the stats, how has the development of the Digital Technologies curriculum impacted on the amount of students, number of schools offering these standards. How can we get more school interested in teaching these standards. The issues of PLD a...

Error Detection - Computer Science Unplugged
http://csunplugged.org/error-detection
Class Simulation of a Computer. The world is noisy place, and errors can occur whenever information is stored or transmitted. Error detection techniques add extra parity bits to data to determine when errors have occurred. Portugese (Brazil) Language Version. The parity tiles on a magnetic blackboard, from a demonstration in Japan. Students trying out CS Unplugged in a High School Classroom, Japan. CS Unplugged in a High School Classroom, Japan. Caitlin helps placing the parity bits. Which can be downloa...

Dominating Sets - Computer Science Unplugged
http://csunplugged.org/dominating-sets
Class Simulation of a Computer. Like the Graph Coloring problem. The dominating set problem is one that no efficient solution has been found for, even though it is very simple to describe. This activity explores the problem, and sets it up as the basis for a the Public Key Encryption activity. Instructions for Dominating sets activity (English). Dominating sets (Polish translation). Has a collection of information on Matching (Graph Theory). Great Principles of Computer Science [info].

Routing and Deadlock - Computer Science Unplugged
http://csunplugged.org/routing-and-deadlock
Class Simulation of a Computer. Computer networks are based on passing messages from computer to computer. This sounds simple in principle, but in practice all sorts of contention and bottlenecks can occur. This activity gives some first hand experience of such issues, with a game for a group of students. Instructions for Routing and Deadlock activity (English). Portugese (Brazil) Language Version. The Routing and Deadlock game in action, from a poster at a conference in Japan. Which can be a nice extens...

Text Compression - Computer Science Unplugged
http://csunplugged.org/text-compression
Class Simulation of a Computer. You Can Say That Again! You Can Say That Again! Many computer users are familiar with compressed formats such as zip, gzip, or gif images. These are based on a method called Ziv-Lempel coding, which turns out to be an interesting exercise in finding patterns in text. Children’s rhymes and stories are good examples for text compression, because they often involve repeated words and sequences. Instructions for Text Compression activity (English). Has an activity Zipping it Up.

Activities - Computer Science Unplugged
http://csunplugged.org/activities
Class Simulation of a Computer. Each Unplugged activity is available to download in PDF format, with full instructions and worksheets. Background sections explain the significance of each activity to computer science, and answers are provided for all problems. All you need for most of these activities are curiosity and enthusiasm. There are photos and videos showing some of the activities in action, and we’ve collected links to other useful resources. Algorithms: Putting Computers to Work.

Programming Languages - Computer Science Unplugged
http://csunplugged.org/programming-languages
Class Simulation of a Computer. Computer programs are sequences of instructions that the computer must follow. There are hundreds of computer languages, but all involve giving clear and unambiguous instructions to a devices that doesn’t understand meanings. This activity demonstrates some of the issues that arise when we try to give precise instructions to achieve a desired outcome. Instructions for Programming Languages activity (English). Portugese (Brazil) Language Version. This activity illustrates t...

Steiner Trees - Computer Science Unplugged
http://csunplugged.org/steiner-trees
Class Simulation of a Computer. The Minimal Spanning Trees. Activity explored techniques for finding efficient networks between points. Are another way to approach the same problem, and they can be used to find even more efficient networks. This is another tough problem from computer science, converted into an activity which is easy to explain, with variations suitable for higher-level students. Instructions for Steiner Trees activity (English). Wikipedia: Steiner Tree Problem. Follow CS Unplugged tweets.

Minimal Spanning Trees - Computer Science Unplugged
http://csunplugged.org/minimal-spanning-trees
Class Simulation of a Computer. Networks are everywhere in modern society: roads, wires, water and gas pipes all connect one place to another. Computers are built of networks at many levels, from the microscopic connections between transistors in a chip to the cables and satellites that link the internet around the world. People who build networks often need to work out the most efficient way to make connections, which can be a difficult problem. Instructions for Minimal Spanning Trees activity (English).
