A tutor came across Dave's blog and ran with the idea to produce a set of 92 quiz cards. Superb!
Hope to gather more resources like this in future.
Regarding transfer of these files to a learner's mobile phone:
1. If the phone has a memory card, this is easily done through a usb memory card reader.
2. The learner may have a cable to attach the phone to a PC for file transfers
3. Bluetooth is a possibility but it would take a while to move 92 cards across, unless the phone is paired via Bluetooth with the computer.
4. If the phone has a data contract, then downloading the cards is a possibility, or even viewing them online.
With regards to doing the same thing using PowerPoint, as Dave Foord has pointed out, you have to rename the first 9 slides as slide01 (zero one) to slide09. My only worry is that people try to cram too much into a slide and so it won't work on a small screen. The beauty of Paint is that it's clunky and that keeps things in perspective, enabling the creation of jpeg quizzes that work on a small screen! If using PowerPoint, remember to change the size of the slide to better suit the portrait format of most phones. Not crucial since the learner can just turn their phone on its side, but navigation is sometimes easier when the phone is the right way up!
