STACK 3.2 for mathematical expressions in Moodle


Hat tip to Tim Hunt for this Moodle addon and video demonstration.

An example of STACK at work

Yesterday I posted on the Calc II course available through as an open course. The Calculus course is using STACK allows students to easily (…well perhaps more easily) enter mathematical notation to answer questions in Moodle and the result/output will automatically create the notation and display it for the student. The demonstration video is a bit better at explaining and you can get a lot more relevant/useful info from Tim Hunt’s update at

From the STACK database entry,

The STACK system is a computer aided assessment package for mathematics, which provides a question type for the Moodle quiz. In computer aided assessment (CAA), there are two classes of question types.
Selected response questions In these questions, a student makes a selection from, or interacts with, potential answers which the teacher has selected. Examples include multiple choice, multiple response and so on
Student-provided answer question In these questions the student’s answer contains the content. It is not a selection. Examples of these are numeric questions.

    Thank you Tim. Now I am experiencing myself building questions in stack. Is there a quick start guide anywhere?
