Computer-aided evaluation of mathematical expressions for quizzes with STACK

by Schnurbusch, Harald -

Closed question formats such as multiple choice questions, in which the answers are merely selected from predefined options, are often not effective in electronic self-tests with mathematical tasks. The question type STACK for the activity "Quiz" offers a remedy for this problem. STACK uses the computer algebra system "Maxima" to evaluate the mathematical expressions that students enter as answers. The input can be for example a variable, a function term, an equation, a matrix or a set. Teachers can create structured templates for a question, based on which different versions of the question are randomly generated and displayed. Maxima uses tests to prove the mathematical properties of the answer input. Based on the properties, feedback is generated with the help of an answer tree and returned to the students as assistance. The question type can be used in all RWTHmoodle course rooms from summer semester 2020 onwards within the activity "Quiz". As an introduction to STACK the RWTHmoodle support provides an own demo course room for STACK, which contains introductory videos, links to the STACK documentation and numerous sample questions and quizzes. To get access to the demo course room and for general questions about STACK please contact the RWTHmoodle support.

Provide an electronic reserves collection in RWTHmoodle - with the literature section

by Schnurbusch, Harald -

The new digital semester apparatus in RWTHmoodle, titled "Literature", enables lecturers to provide their students with a literature list for their courses, which contains either references to electronic resources or PDF scans of the required literature. The scans are created by the university library. Teachers can also attach scans they have made themselves to an entry in the list and have them checked by the library for copyright. In the help section of RWTHmoodle you will find a manual for the Literature section (Electronic reserves collection). It explains how to activate the new literature section, how to add entries and how to submit orders to the university library for digitization or copyright check of texts.

RWTHmoodle Course Rooms for Summer Semester 2020 Now Available

by Schnurbusch, Harald -

The RWTHmoodle course rooms for summer semester 2020 are now available. A manual for how to create a course room through RWTHonline is available in the RWTHonline documentation portal. In summer semester 2020, RWTHmoodle will offer some new and improved features which we will present in more detail in the next few weeks in this news section and in the IT Center Blog. New features are for example the new question type STACK for mathematical exercises in quizzes, an improved editor with a more compact design, and a literature module offering an option to ask the University Library to either digitalize research papers and other literature or do a copy right check on literature lecturers provide themselves. Additionally, we will test two new components: a Sciebo connection and the activity "Virtual Programming Lab" which allows the automatic assessment of programming assignments.
