Engineering Pathways

  1. 1. Engineering'Pathways' Dr.'Brandy'Wiegers,'San'Francisco'State'University' With%Addie%Evans%and%Emiliano%Gomez%
  2. 2. !! of!Engineering!Pathways! Issue:!How'can'we'a<ract'and' retain'a'more'diverse'student'body' in'engineering'programs?' ' Obstacles: ! Lack of Shared Culture! No sense-making! Anti-social! Long math sequence before calculus! Antidotes: ! Collaboration among faculty! Problem solving workshops! Community of support! Double up math classes!
  3. 3. !! of!Engineering!Pathways! •  Goal:'Get'students'through'calculus'and'intro' level'science.' •  Usual'ExpectaFon:'Two'year'process'to'get' through'calculus.' •  Reality:'Usually'takes'much'longer,'adds'1K2' years'to'a'“4'year”'degree.'' •  SoluFon:'1'year'to'get'through'prerequisites' for'calculus'' –  with'support'via'math!workshops!and!tutoring!
