App overload
App overload 
Scheibehenne et al. (2010): 
“there is no clear evidence 
that and when an increase

Taxonomien 
‘animals are divided into: 
(a) belonging to the Emperor, (b) 
embalmed, (c) tame, (d) suckling pigs, 
(e) sirens, (f) fabulous, (g) stray dogs, 
(h) included in the present classification, 
(i) frenzied, (j) innumerable, (k) drawn 
with a very fine camelhair brush, (l) et 
cetera, (m) having just broken the water 
pitcher, (n) that from a long way off look 
like flies’. Michel Foucault, The Order of 
Things (New York: Pantheon, 
1970) xv.
Technologischer Determinismus 
• Taxonomien gaukeln 1-1-Beziehungen vor, 
obwohl es n-n-Beziehungen sind 
• Naive Nutzung der Bloom-Taxonomie 
• Taxonomien führen zu “didaktischer Faulheit” 
• Bloom Dimensionen nicht exklusiv 
• Alternativen: “Klassische” Qualitätssicherung

CPR App Study: Method 
• Expert study (part 1): Independent rating by two 
board-certified emergency physicians 
• 8 test sessions lasting 2 – 4 hours 
• Quality rating on ordinal scale (1 – 10) 
14

• Laymen study in laboratory (part 2): 14 
volunteers (5 female) 
• Following System Usability Scale (SUS) 
approach 
• Per app 5 ratings 
• Each volunteer received 4 – 5 apps 
15
CPR App Study: Results 
• 46 apps out of the original list of 61 have been 
included 
• Of these 13 apps have been selected for the following 
step 
• Substantial interrater reliability (k= 0.61)
