  1. Camtasia 8-11-06

  2. How do we currently teach mathematics in class? • PowerPoint slides

  3. How would you type this in a lecture? Type: int_0^inf pi/(x^3)^(1/2)dx LaTeX: \int_0^\infty\frac{\pi}{\sqrt{x^3}}dx

  4. How do we currently teach mathematics in class? • PowerPoint slides • Whiteboard to add, explain, modify, interact • Back to students • No record kept • Not available to external students • Can’t refer back later • Can’t add to later

  5. How do we currently teach mathematics in class? • PowerPoint slides • Whiteboard to add, explain, modify, interact • Back to students • No record kept • Not available to external students • Can’t refer back later • Can’t add to later • Tablet PC • Write on PowerPoint slides, facing students

  6. How do we deliver up-to-date lecture material to external students? Apart from study book… • PowerPoint slides, prepared for on campus students, with gaps/no answers • Example (PPT) • First attempts to record live lecture audio • No Breeze • Example (Breeze) • Same problem with iplod (and poor audio quality)

  7. What is needed in maths • Handwriting facility • during lectures • in communication (eg emails, chats) • after lectures (additional material, updates) • Recording of handwriting • Screen capture in lectures, afterwards • Example (Camtasia screen capture)

  8. What we need is software that • can capture the screen including audio • live and in your office • allows editing after recording to • cut unwanted bits from live lecture • add extras such as presenter video, movies, quizzes, titles • is easy to use if you don’t want to edit • templates

  9. What we need is (2) also software that • allows exporting in various formats • Flash, Windows Media Video, DivX/XviD, Quicktime MOV, iPod M4V (MP4) • Audio only MP3 • allows choice of quality of audio and video (file size) • contains good compression algorithm • allows live streaming (CQU have done it!)

  10. Comparison • Breeze • No video. Flash only. No compression parameters • Iplod • No video. No compression parameters. No editing • Lectopia • No compression parameters. No editing. Can choose between some formats. • Elluminate • Conference tool. No editing. No compression parameters. In a lecture situation?

  11. More about Camtasia • Record webcasts • Create movies from animated GIFs. • Create animated GIFs • SCORM compliant • Extract audio-only • Add flash quizzes

  12. More about Camtasia (2) • Transitions, PiP (Example camera) • Flash hot spots • Callouts (text, arrows, shapes) • PowerPoint Add-in • Create Flash menu • Zoom-n-pan (?) • Create CD and web menu (?)
