Suggestions for Scriptable CAI Apps?

Corvus9 asks: "I am involved with a University project for creating a Computer-Assisted Instruction application. Currently, we have teachers writing the content and CS students working on the application, which is currently being developed in Flash. However, we would like to make something that would allow teachers and non-CS students to create their own applications. Can Slashdot readers suggest some kind of authoring system that would satisfy this? Commercial and open-source applications are acceptable." "For this to be usable by teachers, we need to provide higher-level constructs like 'multiple-choice test' or 'kinematic model' as base objects, and a scripting model usable by non-computer people whose native language is not English.

I have been searching for an embeddable scripting language to use, and have found nothing satisfactory. Some of the requirements for the scripting language are:

1. Understandable to non-programmers. Our target audience is intelligent professionals who have neither the time nor interest in learning a computer language. Concepts like function calls are very advanced for our users, and things like inheritance or threading are totally beyond them. We need something where a humanities student can look at a script and at least have some idea what it is trying to do.

2. Usable by non-English speakers. Some of our target audience are native French and Spanish speakers. This means that we need to avoid English-language keywords and avoid culture-specific punctuation. For example, in French the decimal separator is a comma, not a period so we must allow users to type in real numbers with either decimal separator, without ambiguity. Also, some ASCII characters like '#', '\', and '{}' are not available on all our user's keyboards. We could allow a 'skinnable UI' that switches between languages, but a French script must be executable on an English document.

3. Extendable. The initial concept is to provide a number of complex scripts like 'multiple-choice test' and allow the end user to customize it. This means that the application must provide some kind of IDE, or integrate with one available for Windows.

4. Create stand-alone courseware. All authoring will be done on Windows PCs, but the created courseware should be executable on Windows and Linux. Mac OS X support would be helpful as well. Flash-compatible output would be preferred."
