In 2004, after giving a presentation on the Eurpopean Language Portfolio (ELP) at the TESOL-Spain National Convention, I was invitied to write a series of articles for English Teaching professional (ETp) http://www.etprofessional.com.
The second article on the Eurpoean Laguage Portfolio (ELP) describes how the Dossier is intended to be used. I also refer to my own teaching experiences about 30 years ago, when I was inadvertently using a kind of ELP Dossier with a group of rather educationally jaded secondary school kids.
This last article on the Eurpoean Language Portfolio (ELP) describes how the Passport draws on records and work referenced and stored in the Biography and Dossier. It represents a comprehensive summary of an individual's learning achievement in foreign languages.

For me, the first example that springs to mind when talking about minimal pairs is ship or sheep. This is almost certainly due to the influence of the title of the well known book Ship or Sheep by Anne Baker. The formula is this: take a word, remove one of the phonemes and replace it with another such that it forms a different word.
