How To Measure The Learning Process In Man-Machine Systems
Matthias Rauterberg, R Aeppli · 1996
: A learning experiment was carried out to investigated the development of mental structures. Six subjects were carefully instructed to operate a commercial database management system (DBMS). The long-term knowledge about general DBMSand computer experience was measured with a questionnaire once at the beginning of the investigation. On three weeks in a row all subjects had to solve the same task twice repeated in an individual session, overall there are six solutions of the same task. At the beginning of each of the three individual sessions the short-term knowledge about the task and the tool was measured with a short questionnaire. For each task solving process all keystrokes were recorded with a time stamp in a logfile. With a special analysing program the logical structure of each empirically observed task solving process was extracted. This logical structure is given as a Petri net. The behavioural complexity (BC) of this net structure can be measured with the McCabe-measure. Wi...
