There is now a new system to generate modular worksheets that can be send to students as a webpage. The teacher can decide which aspects are included in the worksheet (hence modular) and set up a customized session. This can include theoretical explanation, experiment instructions and/or assignments. The system also allows to collect experiment results from students through a web form.
Unfortunately, while the system can handle multiple languages, there is no content in English yet as we are still evaluating the demand. This system is mostly targeted towards academic teaching where masses of students can work online, so please let us know if you are interested in an English version of our worksheets.
