Data Analysis

MPEX II (32 items (1 used to discard responses))

• Independence
• Epistemology
• Other 
• Coherence
• Math (4,18, 39)
• Reality
• Other 
• Concepts (7, 15, 27, 31, 32, 36, 35, 39, 43) 

Interdisciplinary Cluster (10 items - chemistry item removed)

• Physics-Biology link (6)
• Biology-Math link (4)

Physics 131 Fall 2012

Results Summary: Results averaged over 2 instructors (N=22 total). Overall slight positive shift in MPEX (including IC). No shift in interdisciplinary cluster overall, but this is due to positive shift in items probing relevance of physics to biology (6 items - note: one of these (20) is actually about relevance of biology to physics) and negative shift in items probing relevance of mathematics to biology (4 items).

*Math-link in this table is apparently a category I made up that includes items that fall under the "concepts" and "coherence-math" clusters so it can be ignored

Pre MPEX run without IC, N=99.

MPEX-IC questions given as part of pre-PIB. Responses matched with pre-MPEX names to get IC responses for N=87.

Note also that PIB did not include single IC question about chemistry.

Post MPEX included IC, N=74.
