Program Development • Increase degree production via improved monitoring

• Annual graduate student reviews

– Required by Provost

– Used to prioritize TA selections

• NASA Title IX Preliminary Report

– Points to training (central); internal grievance procedures

• Eliminate BAEM, replace it with MS Plan C

– Both coursework only

– Easier to move among options

• Working on 5-year BS/MS program

– Some interest among top undergraduates

– Need to assess cost in terms of faculty time, TA positions

Previous BAEM Changes to Monitor

• First design course: AEM 4331 – Aerospace Vehicle Design

– Covers both Air and Space Craft (mostly aircraft projects)

– Given Fall 2008 as combined course for first time

• Objectives updated to active verbiage (before surveys)

• Added direct measures of outcomes for some key courses Spring 2010 –

need to build up data before can attempt any analysis

• Admission to Upper Division is on a space available basis for Fall 2010

and later Freshmen and the decision has been moved up to after three

semesters instead of four. (College-wide change)

– 45 Students were admitted to the Major January 2013. Welcome

event held on February 12. Second round in May (13 + transfers).

• New Course: AEM 3100 – Software Applications in AEM: Topics for

Fall: Introduction to Matlab and Introduction to Simulink. Spring topic:

Introduction to Linux and its Command Line.
