Image Compression - Making Contact
[This is an update on a previous version] This is a demonstration of an activity from the Computer Science Unplugged collection of games and activities that demonstrate Computer Science without using computers. For more information, see the activity called "Image Representation (Colour by numbers)" at csunplugged.org . The "making contact" theme comes from the 2010 SIGCSE.
Computer Science Buskers? (Error Detection)
This video is a slightly different take on the card trick from the Error detection activity from csunplugged.org - it's a humorous approach to the serious question can we communicate Computer Science concepts to the general public, especially in a situation where we must catch their attention first?

Santa's Dirty Socks (Divide and Conquer Algorithms)
This original story introduces the idea of a divide-and-conquer algorithm using a narrated picture-book verse about the serious problem of finding a pair of dirty socks that have been accidentally wrapped with a child's present. The idea is that this can be played or read to students, and then can be used as the basis for a follow-up discussion. A set of discussion starter questions is available (csunplugged.org to encourage students to engage in computational thinking and think about algorithm analysis in the story 1024 presents are searched in 10 steps, and students can be asked to extend this to other cases, and generally think about the implications of having an algorithm with logarithmic complexity.

Reaching Out (Binary Codes)
This may look like a video that teaches about binary numbers, but it also contains steganographic codes (hidden messages). The lyrics explain how the main code works, but there are many hidden messages in the video using various musical and visual encodings. The codes only use binary numbers, and the video is intended as an extended exercise in working in binary. Some simple warm-up songs and more information are provided at csunplugged.org/modem. The main message is coded in the tune of the song using the same idea as a modem a high tone is a one, and a low tone is a zero. If you decode some of the messages, please don't post them in the comments, so that others can enjoy the challenge too. The hidden messages tell you what to do to get recognition for decoding them. The title of the song is from the theme of the 2011 SIGCSE conference.

acmASCIS - What Is Computer Science ?
What Is Computer Science ? Date: 19-10-2011 Location: Faculty of computer & Information Science - Ain Shams University Event: acmASCIS Opening for 1st Year Students Faculty of Computer & Information Science ... What is it about then? * Fixing windows ... Building a computer .... Learning Microsoft office... Knowing how to surf the Internet ... :huh So that's Computer Science !! * Hmm, is it ? Well, not exactly :) What are we graduating to become then ? * Easy .... A programmer ! Once a man said "Computer science is no more about computers than astronomy is about telescopes." CS is much much more deeper than that ! It's about, ..... why don't you see for yourself ? www.acmascis.org www.facebook.com/acmascis

Programa Onda Digital - Inclusão Pré Digital (Computação "Desplugada")
Projeto Inclusão Pré Digital (Computação "Desplugada") Visa a capacitar alunos e professores da rede estadual de ensino em conceitos básicos de Computação, mediante o desenvolvimento de atividades lúdicas que dispensam o uso do computador. O projeto se fundamenta nas atividades do livro Computer Science Unplugged, de Tim Bell, Ian H. Witten e Mike Fellows. Um dos resultados pioneiros desse projeto consiste na primeira tradução deste livro para o português (disponível gratuitamente no site do projeto Unplugged: csunplugged.org). Além disso, foram realizadas as primeiras experiências práticas de uso de tais atividades em escolas do Brasil. Os próximos passos compreendem a formação de uma rede social de colaboradores, em âmbito nacional, para disseminação dessas atividades e troca de experiências.

Occupy God - Episode 2 "The Read"
www.occupygod.blogspot.com Episode 1 and episode 2 are "mandatory" if you kind of think you might be inclined to check things out down the road. Might be a little tedious (but I hope not) and I might seem like a nutball and crazy but . . . well . . . in any case - it kind of tries to share my "worldview" in advance of the upcoming episodes. - while its still "raw" and on the "ground floor", I hope you'll take a "risk" and share it with people.

Seriously? This is precisely what Sam Harris is talking about Regarding the Biblical passage in the song, in particular "Whoso readeth let him understand". It comes from around Matthew 24:15. INTERESTING bit is that it's verbal quoting of Jesus, supposedly, yet in the text the phrase "Whoso . . " is contained in parentheses. People don't, generally, "speak" in parentheses. Think about.

CS & IT Symposium: Fostering Computational Thinking in Middle and High School
Computer Science Teachers Association Computer Science & Information Technology Symposium 2010 July 13, 2010 Fostering Computational Thinking in Middle and High School Presented by Irene Lee This presentation aims to help teachers and youth providers understand computational thinking (its definition, what it looks like "in the wild," how it can connect with their existing curriculum, and how to nurture computational thinking in today's youth) by sharing rich examples from National Science Foundation funded Innovative Technology Experiences for Students and Teachers (ITEST), Academies for Young Scientists (AYS) and Research and Evaluation on Education in Science and Engineering (REESE) programs. The examples provide a lens through which one can consider the implications for learning and teaching computational thinking skills in grades K through 12.
