Moodle metacourses, part V: The support workflow: Uploading

2011/06/17 2 comments
  1. In Windows Explorer, sort file by name. Select as many files as to make a meaningful content unit (e.g. a component, like lab audio, of a textbook), but not more than 64MB (if Windows Explorer Status bar does not keep count for you, right-click with multiple files selected and choose Properties from the context menu).
  2. Right click on the selection and from the context menu, use 7-zip or the in-built windows Send-to zip-files (neither has a move-files-into-archive option like InfoZip’s command-line zip, so you have to keep track of files completed manually). In 7-zip, you can use “store” which is faster and, unlike attempts of further compressing the already highly optimized input files, should not result in an increase of the file size of the archive.  See zipping screencast.
  3. In the Moodle Resource course corresponding to the language of the file upload, go to lower left corner menu: files, “make a folder”, the name of which identifies the component you are uploading, enter the folder, “upload” the zip file into the folder, next to the file uploaded, click “Unzip”, when done, delete the zip file (to save space). See uploading screencast
  4. Repeat for all resource files (audio and non-audio ) for all languages
  5. see also here on how to batch upload into Moodle

Keyboard overlay stickers improve foreign character writing support in the LRC

2011/06/17 1 comment

Some non-western, but character-based languages benefit from having keyboard overlay stickers installed. Here is a list of what the LRC has:

Amount Languages installed@
3 Arabic 1 list. station, 2 rightmost computers in the front row of the left (teacher perspective) half of the main classroom
2 Farsi 2 rightmost computers in the middle row of the left (teacher perspective) half of the main classroom
1 Greek 1 list. station
3 Russian 1 list. station, 2 rightmost computers of the rear row of the left (teacher perspective) half of the main classroom

Here are photos of the Arabic and Cyrillic keyboards:


We installed the stickers, so that they reflect the software layout of the keyboard that you get when choosing the respective language from the international toolbar. Note that the letters marked in red on the Cyrillic keyboard picture below are not supported by the Russian keyboard layout:


Since only one set can be added to any existing physical keyboard, the teacher computer keyboard can not have an overlay. The student computers with overlays are the listening stations and computers 6,7,12,13,18,19 on the LRC layout map.

Remember that the On-screen-keyboard software remains accessible at all PC’s through clicking “Start”, “Run”, typing “OSK”, clicking "OK".

Example where you can get your own keyboard overlay stickers
