App overload

Scheibehenne et al. (2010):

“there is no clear evidence that and when an increase in choices has a negative impact on variables like satisfaction, preference strength or motivation”

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.

• 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
