Content versus accommodation                              

Explanation:

The accommodation process changes the pattern of a student learning a particular material.

Example: A child diagnosed with dyslexia, may get difficulty in reading a book being studied by the rest of the students. So, he will opt to listen to an audio version of a similar book.

Accommodation of wisdom is more considerable, that requires the learner to reshape them.

Hence, Mr. Henderson is experiencing content versus accommodation.
