Question in How-tos
This question models an experiment: the student must collect some data and enter it at the start of the question, and the expected answers to subsequent parts are marked based on that data.
The student's values of the variables width, depth and height are stored once they move on from the first part.

Question in How-tos
This question models an experiment: the student must collect some data and enter it at the start of the question, and the expected answers to subsequent parts are marked based on that data.
A downside of working this way is that you have to set up the variable replacements on each part of the question. You could avoid this by using explore mode.

Question in Skills Audits for Maths and Stats
This question provides a list of data to the student. They are asked to find the "mode".

Question in Numbas Tut
Calculate the heat losses from a model building based on the U values, dimensions and other parameters specified. In addition calculate the annual running costs and payback period for improvements to the building Fabric.
-
Question in How-tos
This shows one way of laying out matrix cells in a table, so that some cells can be filled in by the student.
At the time this was written, there's an open issue for allowing some entries in the matrix entry part to be filled-in, which would make this technique redundant.
Some CSS in the preamble adds the brackets around the table - it has to have the attribute
class="matrix-gaps"
-
Question in How-tos
This question shows how explore mode can be used to loop through several versions of the same question. The variables for each version are stored in a list of "scenarios", and a counter works through that list each time the student moves on to the next part, labelled "try the next version of this question".
-
Question in How-tos
The student is shown a passage of code in the prompt to a "choose several from a list" part.

Question in CHY1201 - SpectroscopyQuestion requires students to themselves calculate how many electrons are in the conjugated system for the molecules included in this question. As is standard for applications of the "particle in a box" model, the embedded assumption is that one electron is donated to the pi-system by each carbon within the conjugated chain. Students instructed to assume that there are 22 conjugated electrons in Beta-carotene.

Question in How-tos
A custom marking algorithm picks out the names of the constants of integration that the student has used in their answer, and tries mapping them to every permutation of the constants used in the expected answer. The version that agrees the most with the expected answer is used for testing equivalence.
If the student uses fewer constants of integration, it still works (but they must be wrong), and if they use too many, it's still marked correct if the other variables have no impact on the result. For example, adding $+0t$ to an expression which otherwise doesn't use $t$ would have no impact.

Question in How-tos
Should not be used: this relies on a custom JavaScript which is not guaranteed to continue working.
Wrap the student's answer in
set()
so it's marked as a set. -

Question in Demos
Given an unknown list, the student must write Python code to create a copy of it.
There's an alternative to catch the case where the student's variable is just a reference to the original list.

Question in Demos
Given an unknown list, the student has to write code to return the last item in the list.
-
Question in Demos
Given a randomly-generated list, the student must write code to return its first value.
There's an alternative to check if they get the second item, which they might do if they don't realise Python lists are zero-indexed.
-
Question in Demos
The student must write code to compute the standard deviation of an unknown list of measurements.
The suggested answer uses numpy.std.
-
Question in Demos
This is the simplest demonstration of the "code" part type I could think of: write Python to assign
x = 1
.An alternative answer gives a hint if the student's code doesn't define x at all.
