Assessment Plan

• Objective: To measure student learning on a specific topic, meiosis, through the use of specific questions on exams

• Evidence: Performance on multiple choice questions related to this top placing them on:

– a pretest

– an exam during the semester

– the final (use the most challenging questions)

– a pretest for a course that has Bio 110 as a prerequisite (we used Bio 240W)

Assessment Development

• Met with a group of faculty from departments that offer a degree in Biology (UP, Altoona, Behrend,

Abington plus two other interested campuses)

• Initial meeting was seven people plus moderator

• Decided as a group to focus on the single topic – meiosis

• Decided upon using exam questions due to class sizes at UP with the hope of developing a tool that could be used at multiple campuses

• Set up an ANGEL group for assessment

• Wrote the pretest for use in the fall semester and sent it to the members of the group for their comment/use

• Specified learning goals/objectives during the semester

• Helpful strategies

– Involving multiple campuses

– Having a face-to-face meeting

– Having an “outside” moderator

(Suzanne Weinstein)

• Barriers

– Agreeing on questions to use – never reached complete agreement so initial attempt may be of limited use across campuses

– Multiple faculty teaching separate sections of the same course at the same campus using different exams

Initial Data Collection AY 11/12

• So far……

• Fall Bio 110

– Pretest – 44 questions – 7 on meiosis

– Exams 2 and 4 – used 6 of these questions

– Final exam – repeated two questions

• Spring Bio 110

– Pretest – identical to Fall Bio 110

• Spring Bio 240W

– Pretest – used 3 questions relevant to material in that course (need to be able to ask during the semester)
