多媒體演示創新系列(6) – 跟Steve Jobs學演示

我們的學生自少便被誤導「PowerPoint即是演示」,他們以為演示只是隨便複製一堆文字和插入一些罐頭clipart便成,但這幾年來Steve Jobs等科技猛人示範了何謂多媒體演示,以下就是一個頗全面的介紹:

多媒體演示創新系列(5) – HTML5的好處及壞處

新一代網頁標準HTML 5W,成為網絡熱談,因為它不是一個品牌像Adobe FlashW,ICT或夕陽CA可以在考卷直接引用”HTML 5W”,現時仍未有任何教科書(包括長人出版社)提及這概念,故此園丁想在此列出HTML5的pros and cons(相對流行的動畫W軟件 Adobe FlashW):

HTML 5W的好處:
  • Open Source not Proprietary like Flash
  • Uses less computer resources. Uses 20% of computer resources compared to 40% for Flash – this makes a big difference when someone is trying to view anything, regardless of their internet connection (DSL, Cable, Modem, T1, etc.)
  • Improves video and audio quality – extensively – thus your Social Learning/Social Media experience has just increased infinitely; Vivemo, Blip.tv and YouTube (beta) are already offering videos in HTML5 players.
  • Improved interactivity over Flash
  • Eliminates plugins (could it be the end of Silverlight?) Flash requires a plugin (especially for updates) Continue reading 多媒體演示創新系列(5) – HTML5的好處及壞處

多媒體演示創新系列(4) – HTML5圖解

新一代網頁標準HTML 5W,和AppleW雲端W趨勢同步並進,大家最關注的應用就是:在沒有安裝FlashW外掛的環境下,可以直接上網看影片、玩遊戲,甚至做多媒體編輯。
甚麼是HTML5W?看看以下的圖解吧:

[生活分享] 著名籃球教練John Wooden金句集

園丁不諳藍球,但最近得悉美國著名籃球教練John Wooden逝世,享年九十九歲。
他擔任教練廿九年,對年青人必定十分了解,才可寫出以下數十金句,值得老師用來勉勵學生:
  1. A coach is someone who can give correction without causing resentment.
  2. Ability is a poor man’s wealth.
  3. Adversity is the state in which man mostly easily becomes acquainted with himself, being especially free of admirers then.
  4. Be more concerned with your character than your reputation, because your character is what you really are, while your reputation is merely what others think you are.
  5. Be prepared and be honest. Continue reading [生活分享] 著名籃球教練John Wooden金句集

多媒體演示創新系列(3) – 中三學生也可以駕馭Prezi

特首強勢推超錯起錨政改,園丁則近日向學生和教育同工推介演示工具 Prezi,初中學生已經可以駕馭,很欣賞有一位中三學生胡同學,只是聽了我半堂的示範,便學以致用,用了一星期的課餘時間,利用Prezi製作了一個十分出色中文科的演示《中國文字的字形演變和由來》:

  1. Prezi的好處是將概念圖W(concept mapW)和演示二合為一,學生能掌握演示內容的整幅圖畫(whole picture),對學習十分有益;
  2. 只要開始便選擇中文範本,整體對中文支援比想像中好;
  3. 只要在文字區貼上YouTubeW的超連結,便會變成YouTube播放物件,一樣可以旋轉及放大,暫不支援內地同類網站;
  4. 除了圖檔,可上載pdf, swf, flv檔案;
  5. 不要由零開始,只要在Showcase中選擇”Reuse Prezi”,便可複製副本在自己空間,開啟便可編輯。
