iXam - Online Assessment System for chemists

iXam is a webbased assessment system with special focus on the needs of chemistry education.

The system is based on LibreEOL - Exams On Line and extended with the following question types:

  • Random Numeric: Questions are prepared using random values within the question text, e.g. "0.26 g of sodium oxalate is dissolved in a flask and requires 30.74 mL of potassium permanganate (from a buret) to titrate it and cause it to turn pink (the end point). What is the molarity of the potassium permanganate?" - The weight of sodium oxalate and the volume of potassium permanganate get different values for every candidate/test
  • Chemical Structure: Structures of organic compounds can be drawn within the test using JavaScript-Code and can automatically be matched against given answers.
  • Chemical Equations: using a rich text editor candidates can enter equations for redox reactions or ion equations like "NH4+ + B(OH)4- + HCl → NH4Cl + B(OH)2 + H2O" - the system can match against given answers, even if they are written in different order
  • ...

In addition we have the following features:

  • Authentication agains university credentials
  • Different templates/layouts are possible to comply the corporate identity
  • Test reports as PDF-files to candidates or examiner
  • unattended videomonitoring of the test-session using BigBlueButton, with analysis for cheating situations by face recognition
  • ...
