It takes a village to raise a scientist Craig Ogilvie, Iowa State University • 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 cogilvie@iastate.edu
Loss of STEM majors @ ISU Loss mainly in 1st and 2nd year 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. cogilvie@iastate.edu
Confronting reasons that students leave STEM • Why Undergraduates Leave the Sciences. Seymour and Hewitt, 1997 • Loss of interest in the subject matter of science • Belief that a non-science major would offer a better education • Losses occur among the best qualified students • Losses 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 cogilvie@iastate.edu
Inquiry intro labs: each >1000 students B A • Biology • A, Cookbook: identification labels and detailed lab instructions • B, Inquiry: Identify plants 1, 2, 3. What are key phyla differences? • Physics • A, Cookbook: measure P, V, T of gas and plot P vs V etc. • B, Inquiry: Determine if air exhibits properties of an ideal gas. cogilvie@iastate.edu
Class as scientific community Teaching Assistant training on using inquiry processes is vital. cogilvie@iastate.edu
Student research • Classic model: 1-on-1 mentoring • Scale? • Additional model, courses 20-300 students • 5-6 week research project in lab courses ROLE project, UPR-Mayaguez cogilvie@iastate.edu
Course-based student research @ISU • 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 cogilvie@iastate.edu
Student engagement in large “lectures”: Flipped classes Use face-to-face class time for tasks that require a community • Wrestle with new concepts via group discussions • Scaffold skills, complex problems Students work on lower-level skills, video clips, before/afterclass In Class Out of Class From RobertTalbert cogilvie@iastate.edu
Village Large face-to-face meeting Lab 1 Lab 1 Lab II Lab II Inquiry lab Research lab Lab 1 Lab 1 Lab II Lab 1 Upper 1 Upper I Lab II Upper II Upper II cogilvie@iastate.edu
8500 students impacted/year cogilvie@iastate.edu
Assessment • Students’ understanding of Nature of Science after research labs • Consistent increase • Encouraging since lack of creativity was one reason for leaving • Gains also on content knowledge (bio), but no changes in efficacy cogilvie@iastate.edu
Retention Uptick post reform, hard to prove cause Kept 3% c.f. prior 25% loss, changed 1 in 9 students’ decision cogilvie@iastate.edu
Lesson I: Emergent change, learning organization • Faculty Learning Communities • Time/space to discuss what change is needed • Support during implementation • 80+ faculty involved • Science educator postdocs • Bring energy, time, expertise and short-timescale • Graduate TA Learning Communities (GTALC) • How students learn • Led by senior TAs and postdocs cogilvie@iastate.edu
Lesson II: Productive TensionExperiential learning vs calls to lower costs What skills do graduates need to help solve 21st century challenges? • Innovation • Team – work • Ongoing drive to learn/adapt • Communication Experiential learning can help develop these skills • Research experiences • Extra-curricular student groups Considerable concern about costs of higher ed, tuition, debt…. Resolution? Redirect existing activities into experiential learningwith little extra costs, courses, extra-curricular projects,…. http://www.aacu.org/leap/documents/2013_EmployerSurvey.pdf cogilvie@iastate.edu
Invest in experiential learning as higher priority than student admin, dorms, rec centers,… • Student Innovation Center @ ISU (proposed) • Out of dark basements into prime real-estate • Competitive advantage for residential university Canon Design cogilvie@iastate.edu
Invest resources in experiential learning • Lab-space for course-based research • Space for extra-curricula organizations, cross-fertilization Canon Design cogilvie@iastate.edu
Conclusions • Refocused our science labs at ISU • Inquiry rather than cookbook when ~1000 students • 5-6 week research projects when 20-300 students • Higher-level cognitive work in large class meetings (flip) • Lessons • Emergent change • Faculty learning communities: time/space to plan • Postdocs bring in energy, expertise • Productive tension: experiential learning vs calls to reduce costs • Impact more students at similar cost • Projects improve quality: innovation, team-work, communication cogilvie@iastate.edu

Iowa State University • Residential Land Grant university, 32,000 students Fall13 • 6000 more students than in 2005 • Rich tradition in agriculture, science, engineering,… • Learning communities, extra-curricular student groups cogilvie@iastate.edu
Student Reaction Inquiry introductory labs • "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.” cogilvie@iastate.edu

Analytics • Use data on who is not being retained as science major at ISU • 1300 new science majors from HS • 70% stay as major after 1-year • 17% leave ISU after 1-year • 13% leave science after 1-year but stay at ISU • Science-switchers • Broad range of ACT scores • Lower math diagnostic scores (rational numbers, radicals) • Lower self-efficacy, confidence (MAP-works 5 week survey) • Predictive model of high-risk switchers? • Advising, bridge programs, pre-calc math….. cogilvie@iastate.edu

Intro bio lectures, bio 212: • National and ISU concern that courses were sequence of factoids • FLCs discussed, forged consensus on big-picture outcomes, e.g. 212 • Cellular / molecular basis of life, including an understanding of scale, biological membranes, and basic cellular structure and function • Transmission and expression of genetic information • Bioenergetics & carbon and nitrogen cycles • Compare and contrast plants, animals, and microbes • 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 cogilvie@iastate.edu
Research projects in lab courses cogilvie@iastate.edu
Increasing diversity • Many under-represented students start at community college • Challenge is transfer to 4-year + continue as science major • Potential key is student’s identity as a young scientist • ~10 students nominated by CC faculty • 8 weeks summer research-work in ISU faculty labs • Summer after first year of CC, return to CC for sophomore year • Math/bio coursework + field trips Summer 2012 scholars cogilvie@iastate.edu
