To set up pedagogical experiments in a virtual lab: methodology and first results

This paper concerns a methodology for setting up web based experiments by distinguishing two perspectives: the learning perspective (which tasks will be scheduled for pupils and tutors, how they are planned and what learning objectives they may attempt), and separately, the experiment perspective (how teachers or researchers may use trails of this experiment, the first to improve their teaching, the last to various research objectives). The both are described by computable “scenarios” expressed with an educational modeling language, Learning Design Language (LDL). Scenarios are then implemented on a platform (LearningLab platform) to be played by pupils and tutors and further analyzed by exploiting trails of each run
