We've been using STACK 3 since September here in Birmingham, and I'm very pleased to report how successful this has been. The period has seen us fix a number of minor bugs, consolidate the design in some areas and generally make substantial improvements.
It gives me great pleasure to announce the release of a significantly update "Demonstration course" for STACK 3.0. This contains about 450 STACK questions licensed under a Creative Commons Attribution-ShareAlike 3.0 Unported License.
This is distributed with the latest qtype_stack code, in the directory "samplequestions". Anyone running STACK already will need to update their code to the latest version in order to run all the questions in this course successfully.
There are comprehensive question sets in algebraic manipulation, and in procedural practice of calculus. There are also a number of other demonstration questions, arranged into quizzes.
These should act as a useful starting point for question authors.
The majority of questions have
- random versions (where appropriate)
- general feedback, i.e. a worked solution
- specific feedback to common incorrect answers
- question tests,
A number of random versions have been deployed, and the questions arranged into quizzes of reasonable lengths.
The primary aim of this course is a demonstration, hence without a specific group of students in mind some of the worked solutions and feedback inevitably looks inconsistent. This is compounded by the compilation of questions from a number of authors. If you make use of these materials in any ways I'd very much appreciate a short update on your experiences.
I would be delighted to included quizzes in other areas of mathematics as demonstrations. Please send me your materials!
