Using STACK with Moodle in the Physics Laboratory to review the results of student experiments and their evaluation

Abstract: In the physics lab at the HTW we use STACK with Moodle for the review of the results of laboratory experiments. The entire evaluation of the experimental results (including the expression of uncertainties) is checked by means of STACK queries. Very comprehensive queries are summarized in amalgamated Moodle tasks. In particular, the verification of the number of significant digits in combination with an automated, differentiated feedback for students represents a big challenge in this context.
