  1. 1. Recording lectures Daníel B. Sigurgeirsson dabs@ru.is
  2. 2. Recording lectures● Why we should record lectures● What are the pros/cons● A few advises about the implementation● What tools to use● Tips/tricks
  3. 3. Benefits● If a student misses a class, (s)he can still benefit from the lecture by watching it later ○ there can be a million reasons why a student misses a class, some of the because (s)hes lazy, but there are also a lot of legitimate reasons● Students dont always "get" things right away, and might want to revisit some particular topic ○ watching the lecture again (or a part of it) can be very useful ○ sometimes the teacher talks too fast, sometimes too slow...
  4. 4. Drawbacks● If we only record the screen: ○ we cant use the whiteboard! ○ various gestures wont be recorded● Questions asked by the students wont be audible in the recording● If the teacher says something stupid, it can be played back again and again!● Setting up the recording environment requires practice
  5. 5. What about the equipment?● Wont I need a cordless microphone plus some expensive receiver? ○ Not necessarily ○ The only thing you need is a simple headset with a microphone (and a cord). You arent going to be walking around the room anyway ○ Available here
  6. 6. Recording software● The most common software for screen capture is Camtasia (http://www.techsmith.com/)● Other (open source) options are available (see here for instance)
  7. 7. Questions from the students● While lecturing, a question may be asked by a student● The question will probably not be audible in the recording● The teacher must take care of repeating the question after the student has asked it ○ this is actually also useful for at least two other reasons: ■ other students might not have heard the question ■ it will help to prevent misunderstanding, as the teacher will usually rephrase the question, and therefore ensure he understood it correctly the first time● Start doing this right away, it will become second nature very quickly
  8. 8. Tools that might replace the whiteboard● Some computers have fancy screens which allow us to draw directly to them, using a special pen● This is fine where it is available, but not necessary at all (and I dont recommend getting too attached to such a device)● Other tools can replace the whiteboard and/or a special device in 95 - 99% cases: ○ Notepad ○ MSPaint ○ Google Docs● Note: these tools are all preinstalled and dont need any additional configuration
  9. 9. Notepad● ... or whatever text editor you prefer ○ I use Notepad because it loads fast, and it is guaranteed to be installed on all machines● Very useful if all you do is write text● Tip: to ensure students at the back of the room can read the text, you should increase the font size! ○ 14 - 16 pixels is usually fine
  10. 10. Drawing programs● Sometimes, writing text isnt enough● MSPaint is a simple drawing program - and it turns out we only need simple programs! ○ the whiteboard isnt that complicated is it?● If you use Google Docs, there is a drawing application there as well ○ easy to share images with students
  11. 11. Pre-recorded lectures● Recording lectures beforehand without student participation is also an option● Drawbacks: ○ students cannot ask questions!● Benefits: ○ students cannot ask questions!
  12. 12. What do students prefer?● In a recent (very non-scientific) study, where 49 students participated, 25 of them preferred the option of being able to attend lectures, 18 preferred pre-recorded lectures, and 6 didnt care
  13. 13. Uploading lectures● Making lectures available on the school website is one option● Another is to upload it to YouTube and/or iTunes● If you use YouTube, you will need the following: ○ a Google account ○ many of your recordings will be too big for YouTube by default, but you can request permission to upload bigger recordings
  14. 14. Tips/tricks ● In drawing programs (MSPaint, Google drawings), holding the shift key down will: ○ draw horizontal/vertical lines while drawing lines ○ draw a circle while drawing an ellipse ○ etc. ● In Google Docs, press Ctrl and + (the plus key) to get a list of keyboard shortcuts ● Check out www.khanacademy.org which uses videos exclusively
  15. 15. Questions?
