units-filter

Parser for expressions concerning physical values

Units-filter is a basic standalone filter written in C language, flex and bison. It inputs strings like "1.5e3 nN.m.s^-1" (it could be the time growth ratio of a torque) and outputs the value in standard SI unit, followed by the physical dimension of this value. example :~/src$ echo 1.5e3 nN.m.s^-1 | units-filter 1.5e-06   2   1  -3   0   0   0   0    0    0 2 -3 which means : 1.5e-06 (SI unit) m .kg.s This parser can be embedded in educational test systems, in order to analyze a student's answer to a problem of physics or chemistry.

wims

server for educational content: courses, exercises, and exams

The WWW Interactive Multipurpose Server is an educational platform originally developed for mathematics but now also supporting subjects such as physics, chemistry, biology, and languages. WIMS features a rich set of resources and exercises either for autodidactical use or for training classes, including: * exercises with automatic feedback and correction, allowing the learners to work at their own pace; * interactive exercises with randomly assigned data, allowing the learners to work on the same type of exercise but with different data and as often as they wish; * exercises with an automatic scoring system, which enhances learner motivation; * user-friendly graphics and calculation tools; * courses and documents with hyperlinks to the exercise pool; examples in the courses can be made random, so the student can get more than one instance of an illustration for tricky concepts; * support for exams with pre-published contents. As each individual exam will have randomly chosen data, training is possible but writing each response in advance is not. This package contains the WIMS FastCGI server, serving Open Exercise Format (OEF) documents. OEF is a very high-level language which allows authors to focus on pedagogical issues.
