It takes a village to raise a scientist
July 15, 20131
• Howard Hughes Medical Institute grant (2010-14)• Engaging all 1st and 2nd year STEM students @ ISU
in authentic science projects• General lessons for large scale education reform
Loss of STEM majors @ ISU
July 15, 20132
Presidential Council (PCAST) Report 7 Feb 2012“…increasing the retention of STEM majors from 40% to 50% would generate three-quarters of the targeted 1 million additional STEM degrees over the next decade.
Loss mainly in 1st and 2nd year
Confronting reasons that students leave STEM
July 15, 20133
Why Undergraduates Leave the Sciences. Seymour and Hewitt, 1997Loss of interest in the subject matter of scienceBelief that a non-science major would offer a better education
Losses occur among the best qualified studentsLosses occur also due to math challenges, low-resilience,…PCAST recommendations: Engage to excel
Widespread adoption of empirically validated teaching practices; Replace standard laboratory courses with discovery-based
research courses;Improving retention will also improve quality STEM education
Inquiry intro labs: each >1000 students
July 15, 20134
BiologyA, Cookbook: identification labels and detailed lab instructionsB, Inquiry: Identify plants 1, 2, 3. What are key phyla differences?
PhysicsA, Cookbook: measure P, V, T of gas and plot P vs V etc.B, Inquiry: Determine if air exhibits properties of an ideal gas.

Class as scientific community

Teaching Assistant training onusing inquiry processes is vital.
Student research

Classic model: 1-on-1 mentoringScale?
Additional model, courses 20-300 students5-6 week research project in lab courses
ROLE project, UPR-Mayaguez
Course-based student research @ISU
July 15, 20137
Freshman chemistry major lab (Chem201)Design and test CO2 reduction processes and catalysts as part
of a faculty’s chemistry research program. In Geology 100, students characterize the local watershed
via high-tech diagnostic wells
12 research-lab courses @ ISU: Over 850 students/year
Student engagement in large “lectures”: Flipped classes
July 15, 20138
Use face-to-face class time for tasks that require a community
Wrestle with new concepts via group discussions
Scaffold skills, complex problemsStudents work on lower-level skills, video clips, before/after class

Assessment
July 15, 201311
Students’ understanding of Nature of Science after research labs
• Encouraging since lack of creativity was one reason for leaving• Gains also on content knowledge (bio), but no changes in efficacy
• Consistent increase
Retention
July 15, 201312
Uptick post reform, hard to prove causeKept 3% c.f. prior 25% loss, changed 1 in 9 students’ decision
Lesson I: Emergent change, learning organization
July 15, [email protected]
Faculty Learning Communities Time/space to discuss what
change is needed Support during implementation80+ faculty involved
Science educator postdocs Bring energy, time, expertise
and short-timescaleGraduate TA Learning
Communities (GTALC)How students learnLed by senior TAs and postdocs
Lesson II: Productive TensionExperiential learning vs calls to lower costs
July 15, 201314
What skills do graduates need to help solve 21st century challenges?InnovationTeam – workOngoing drive to learn/adaptCommunicationExperiential learning can help develop these skills• Research experiences• Extra-curricular student groupsConsiderable concern about costs of higher ed, tuition, debt….Resolution? Redirect existing activities into experiential learning with little extra costs, courses, extra-curricular projects,….

Conclusions
July 15, 201317
Refocused our science labs at ISUInquiry rather than cookbook when ~1000 students5-6 week research projects when 20-300 students
Higher-level cognitive work in large class meetings (flip) Lessons
1. Emergent changeFaculty learning communities: time/space to planPostdocs bring in energy, expertise
2. Productive tension: experiential learning vs calls to reduce costsImpact more students at similar costProjects improve quality: innovation, team-work, communication

Student Reaction Inquiry introductory labs
July 15, 201321
"I really enjoyed that we were encouraged to answer our own experimental questions, even at the cost of finishing a planned activity for the lab. It enabled us to be interested in and take an active role in our learning, rather than simply following step by step the lab activities.”

Intro bio lectures, bio 212:
July 15, 201327
National and ISU concern that courses were sequence of factoids FLCs discussed, forged consensus on big-picture outcomes, e.g. 2121. Cellular / molecular basis of life, including an understanding of scale, biological
membranes, and basic cellular structure and function2. Transmission and expression of genetic information3. Bioenergetics & carbon and nitrogen cycles4. Compare and contrast plants, animals, and microbes5. Understanding how science is conducted and why it is important. Assess, teach for these big picture goals
Active learning in large lectures with undergraduate learning assistants First results showed very little gain in student understanding Some growth in student efficacy
Improve active learning materials, more attention to Karplus learning cycle
