1. Your example doesn't compile.

2. Your example contains a lot of unnecessary stuff.

3. You're using the \m command wrong, the command is used to create
inline math and shouldn't be needed (with a few exceptions) in a formula
environment.

Change the formula to

\starttext

\startformula
   u × (v × w) = u ×
   \startmathmatrix[fences=parenthesis]
   \NC v_2w_3 \NC - \NC v_3w_2 \NR
   \NC v_3w_1 \NC - \NC v_3w_2\NR
   \stopmathmatrix
\stopformula

\stoptext

and it should be centered. The paragraph before the formula can be
changed to

Wir berechnen \m {u × (v × w)}:
