"Free LiveCode Course Material "

"Computer science and the technologies it enables now lie at the heart of our economy and the way we live our lives."

"K-8 Intro to Computer Science is a free course that aims to demystify computer science and show K-8 students that it's fun, collaborative, and creative. The course is designed to motivate students and educators to continue learning computer science to improve real world relationships, connections, and life. Educators will foster an environment of communal learning that emphasizes risk-taking. This course will teach students about computer science, computational thinking, and programming. It will also teach that success does not come on the first try, just like the world's most difficult problems aren't solved on the first try. Challenge is good when it is supported by plans and tools that lead to success. This course will help students persevere in solving problems."

"EFS 693B - STANFORD UNIVERSITY Advanced Listening and Vocabulary Development (...) TED Talks Introduction Below are groups of TED Talks, curated from http://www.ted.com and organized roughly by level and topic. You should do a full group (divided across several sessions if desired) and see if the integration makes them easier to understand (especially the later ones). Be sure to interact with them--don't just watch all of them straight through. However, you can do all or parts of some more intensively than others. Use your best judgment, and return to previous class notes as needed. Note that you are provided with the following information about the talk: 1. length 2. the overall speed in words-per-minute (WPM) 3. the vocabulary profile by percent of words at set frequency levels of the British National Corpus (3K, 5K, 10K, and more than 20K (off-list=OL)) 4. Accent (US, British, etc.) 5. Comments 6. Brief description of the content (from the TED website) (...) Last modified November 12, 2013, by Phil Hubbard"

Molto interessante e sopratutto utile grazie!

Grazie, Fabrizio, Ho taggato con "EFS_Stanford" - tra altri tag - questo webquest e i video ivi elencati dopo un webinar con Phil Hubbard organizzato via hangout da Vance Stevens domenica scorsa (8 ottobre). Nel webinar Hubbard ha insistito sul fatto che la forma di webquest direttivo era meglio delle forme di collaborazione sociali come tagging e condivisione, perché gli consentiva, da esperto, di dare informazioni coerenti. Allora taggare queste sue risorse TED su Diigo è anche un modo di esprimere il mio dissenso ;-) In effetti a proposito di http://www.ted.com/talks/gel_gotta_share.html , elencato in questo webquest, dice di non poter indicare le parole per minuto "perché non c'è trascrizione". Invece c'è, se si va alla pagina YT originale del video embeddato. Ora se invece di un webquest statico avesse condiviso questa risorsa con i suoi studenti in un gruppo come questo, c'è da scommettere che almeno uno di loro avrebbe rimediato all'errore in un commento - come d'altronde ho fatto in https://groups.diigo.com/group/ltis13/content/tag/EFS_Stanford%20GelConference ...

(*) Actually, this TED page has an English subtitle-generated transcript (as well as translated transcripts in the 47 other languages the video is subtitled in). And the transcript in http://amara.org/en/videos/h60BL6bU49WF/en/2426/ page where the English subtitles were made shows an average 90 wpm in the passages where Collins actually speaks. This remains rather slow indeed, however non natives may find it difficult to grasp the written texts that appear very briefly on-screen, and hence Collins' allusions to these texts. (CA)

I just thought that was crazy and amazing. There's no chance I would have reached that student just by what I was doing before."
