What is STACK?
According to externe Seitetheir own website:
STACK is an assessment system for mathematics, science and related disciplines, designed to enable students to answer questions with a mathematical expression, such as a polynomial. Students are not limited to multiple choice.
Below is a typical STACK question. Note that the student's answer can be any algebraic expression, and that their answer is interpreted by the system before it is marked. This allows the student to confirm the answer is what they intended before being marked. Notice also the automatically generated feedback.
Here at ETH, STACK is available as a question type in Moodle courses. No further installations or configurations are required. More information for interested lecturers and lecture organisers is available in the detailed externe SeiteSTACK Documentation or at Using STACK at ETH.
