How do we best prepare our students to work in an

interdisciplinary environment?

Page 6: An Integrated Science Curriculum for First Year Students Lisa Gentile

When a group of faculty met in 2007 to ask that question UR had strong momentum:

•Renovated Science Center housing chemistry, biology, physics•New science faculty positions (including 2 “interdisciplinary” science faculty from UR’s first HHMI grant)•Strong science students•$900,000 Science Education Grant #1 from HHMI •Success in securing external funding from major programs to increase interdisciplinary work

Page 7: An Integrated Science Curriculum for First Year Students Lisa Gentile

Teach the material from the first course in each of biology, chemistry, physics, mathematics, and computer science as one, integrated course.

Course team-taught by 5 faculty, one from each discipline.

Includes a hypothesis-driven, discovery based lab and a workshop.

Students then go on to complete a traditional major in any discipline.

Reassigned time to develop/implement/teach the course

Fall SpringYr 1 (development):

1 course of 3 2 courses of 2

Yr 2 (first time teaching): 1 course of 2 Teaching (counts as “3”)

IQS Learning Goals:

• Increased interdisciplinary and disciplinary understanding by students

•Increased interdisciplinary understanding by faculty, as seen in the quality of integration in lectures and lab

•Increased number of faculty in STEM disciplines equipped to create courses that draw on concepts from multiple disciplines

•Increased number of students pursuing cross-disciplinary opportunities at our institution and beyond

•Increased use by faculty of connections to other disciplines in their discipline-based courses.

Lessons learned •Allow the idea to come from the faculty and to allow us to define what we need to make it work.

•Allow ample time for both development and implementation

•Focus on group unity and community building activities

•Ultimate faculty development

Page 19: An Integrated Science Curriculum for First Year Students Lisa Gentile

Challenges•“Full” integration of the material

•Team teaching with 5 faculty members from different disciplines

•Small departments- development/early implementation stages

•Computer science

•Student selection

Evaluation Questions

2. How did teaching IQS change the way in which faculty teach other courses?

a. New cross-disciplinary courses at the upper level are developed and taught: three new interdisciplinary courses have been designed for the IS minor (systems biology, theoretical/computational chemistry, structural biology)

b. Examples, exercises, and problems that emphasize interdisciplinary understanding developed for the IQS course are used by faculty in traditional discipline-specific courses.

Page 35: An Integrated Science Curriculum for First Year Students Lisa Gentile

Evaluation Questions

3. Are concepts from each discipline integrated in lectures and labs developed for IQS course?

a. faculty designed and added new integrated projects to the second offering of IQS
