Hi,

ImageQuiz uses a cvs file format for questions. I have added an XML file
format. Currently, both files are used to load questions
into an sqllite database.

For me, the problem is figuring out how to interface with the
journal/datastore. In a hierarchical file system, quizzes would be sets of
questions
in XML or CVS format within categories determined by the folder names. An
imagequiz_library would be a base folder containing these quizzes. This
organization does not map well to the journal/datastore at present. In time,
there will be a journal objectchooser which can show entries of the proper
mimetype in the journal or in specific repositories on the schoolserver, usb
keys, etc.

Another problem is whether the unit should be a set of questions or a
question. This is similar to the issue of where to store an image or mp3
file and how to organize a set of them. Perhaps the journal could have an
album where a single question (or image or mp3) could be located by tag
(album name) by looking in many different albums (similar to picasso for
example).

The implementation I am working on will find sets of questions (called
quizzes) and map them into categories based on the folder structure. The
base will be 'imagequiz_library' and, hopefully, there would be one in the
activity bundle (built-in samples), on the schoolserver, and on removable
drives.

The focus of ImageQuiz is matching an image or a place in an image to the
answer to a question. For language learning, I am setting up a question bank
where the question is an audio clip (e.g. 'ball' spoken in the target
language), and a set of pictures, one of which shows a ball (or a picture of
several objects where the answer is to click on the ball). ImageQuiz will
also support standard flash cards (text question, text answer) plus
combinations like audio question, text answer. Sadly, speech recognition
isn't ready to support audio question, audio answer.
