I am trying to write chemistry quiz questions, where the student must balance an equation by filling in integer numbers (coefficients) in front of products and reactants in an equation.
1 CH4 + 2 O2 --> 1 CO2 + 2 H2O
the cloze type works, but I want to give an all or nothing grade. The student either balanced it correctly or they didn't. I cannot find any way to grade them together as an all or nothing fill-in-the-blank, I've searched the forums and have only found a few ideas for other question types i'll be needing soon, but nothing useful for this. I am using Moodle 2.6.
Does anyone have any ideas?
