[Etoys] two hours of tales (squeak etoy video tutorials)
by Timothy Falconer 18 Oct '07

18 Oct '07

I've just posted my eighth 15-minute Squeaky Tales tutorial, bringing the collective time to two hours of Etoys fun: http://waveplace.com/movies/ My plan is to create four 15-minute movies each week for the next eight weeks for a total of ten hours of video tutorial. How does this translate to the classroom? I'm not completely sure yet, but I'd guess that each 15-minute tutorial could form the basis for an hour of hands-on instruction, with the mentor first presenting the concepts in their own fashion, then leading the class for the remainder of the time. The videos themselves are aimed at the mentor, not at the students, though I suspect older students could watch the videos on their own. What topics will I cover? Well, I'm trying to make the Squeaky Tales series as subject-neutral as possible. My hope is that this approach will allow mentors to adapt the concepts to different ages and subjects more easily. By necessity, there will be rudimentary math concepts like addition and multiplication, but these will be presented as a means to another end, not a discussion of math itself. As the name of the series implies, my ultimate goal is storytelling. I'm teaching programming as a means to telling stories, which hopefully will engage students that might otherwise be timid about math and science.

I would like to try my hand at creating some etoys videos. What open source video creation / capture software do you recommend using to capture the etoy screen and narration audio? I'm running etoys on a windoze PC. Thanks, Dave Raftery http://squeak.pbwiki.com

[Etoys] ogg vorbis support for etoys tutorial movies (now works on XO)
by Timothy Falconer 17 Oct '07

17 Oct '07

Hi all, Today I added support for Ogg Vorbis to my Squeak Etoys video tutorials, and verified that they play on the XO. http://waveplace.com/movies/ The next obvious step is to embed the ogg files in a web page, so you can navigate the tutorials like you can with the Flash FLV versions. As it is now, you have to click "back" to see the list, remember which number you're on, and click the ogg button again. A prev / next nav is the safer way to travel. Can anyone point me to an example of embedding ogg vorbis into a web page so it'll stream on the XO? Also, let me know your experience regarding volume levels. All but #6 seem too quiet to me, but I want other's input before I re-encode them louder. Could just be the B4 speakers, or the build I'm using. If someone likes these enough to post them on an official XO link page, I'll make an ogg only page just for the XO. Thanks, Tim

Re: [Etoys] DrGeoII for OLPC

Hi Hilaire -- I was just at OLPC yesterday and Walter Bender showed me Dr. Geo and its movies on his XO. All seemed to work fine. (Walter really likes Dr Geo!) The movies were in OG format and were streamed from the classroom server. This seems like a very good route for quick useful documentations and demos for XO users around the world.

[Etoys] squeaky tale #2
by Timothy Falconer 15 Oct '07

15 Oct '07

Hi folks, Over the long weekend, I got some very positive feedback regarding my Squeaky Tales series. People seemed to like my movies, though my first attempts had some video compression snags which forced me to temporarily abandon Flash video in favor of Quicktime. The downside was that the movies took a long time to start, since they were essentially fully downloading before beginning. Today I worked out the kinks and encoded them back as Flash FLV movies. They should start up more quickly and should also be more compatible with different systems. FLV is the same format used on YouTube. I just posted Squeaky Tale #2, which introduces a new character in the plot besides Seymour the turtle. As before, let me know if you have any problems. Also, keep the kudos coming. It helps to know you're out there! To watch the movies, visit: http://waveplace.com/movies/ Thanks, Tim

[Etoys] DrGeoII for OLPC
by Hilaire Fernandes 14 Oct '07

14 Oct '07

I am please to announce a ready to use version of DrGeoII for Squeak OLPC. Thanks to the help of Spanish Squeaker José Rodríguez, we have build a SAR archive containing localization in English, French & Spanish. ftp://ftp.ofset.org/squeak/drgeo/ To install DrGeoII, you just need to download the DrGeoII.sar file from the previous location and drag and drop it in the image, then chose "install drgeoII.sar" from the popup menu. If unsure, review the videos coming along the DrGeoII.sar file. For recall, DrGeoII is an interactive geometry framework, Morphic based and Smalltalk programmed, which can be embedded and mixed with any existing Morph user interface element of the Squeak OLPC environment. As the confusion between interactive geometry and vector drawing is very common, I have produced a few video recording exposing the installation and the use of the framework. Moreover the videos show how the Morph UI gives freedom to mix in a constructive manner various unrelated Morph components (user interface construction, user interface scripting between different unrelated components). Let's revitalize the Squeak/Smalltalk/Morph jewels for the development of educative application... Hilaire -- http://blog.ofset.org/hilaire Smalltalkers do: [:it | All with: Class, (And love: it)]

Just a small observation - when the submenu is pinned, the main menu stays up and gets deleted only when the first menu item in the submenu is picked. Shouldn't it be deleted when the submenu gets pinned? Apologies for the delayed response. I was on vacation. Subbu
