Engaging all undergraduate science students in course-based research projects Craig Ogilvie, Iowa State University, Vision: Every time a student steps into a science classroom, they will be doing/discussing science with their peers 1000+ students/yr research projects in last 5-6 weeks of lab courses Typology of research experiences Assessment results: impact on students Next steps 1 Nov 3, 2014 How to get more students engaged in research? Different types of 5-week projects in lab courses Depth of experience 2 Individual student in faculty lab
Constraint: operational costs ~ same as traditional labs Student research Class idea, done coopted in course into Class-wide, faculty lab linked projects Student extensions of inquiry labs Inquiry labs Reach more students Nov 3, 2014 Student-driven extensions of inquiry labs Human Physiology (470 students) Students complete standard human physiology investigations. After each lab, asked to develop a hypothesis would they be
able to test using the protocols they had just learned. Students received constructive feedback from TAs Final 4 weeks of the semester, student teams chose one of their proposed investigations as a research project. 3 Nov 3, 2014 Class-wide, linked projects Intro Geology (150 students) Student groups studied surface water and groundwater quality issues using monitoring wells. Each group developed an open-ended research question. collected, synthesized and summarized the data, and presented their results in a conference-style poster session. 4 Nov 3, 2014 Class coopted
into faculty lab Genetics (325 students) Students unofficially joined the NSF Engineering Research Center for Biorenewable Chemicals (CBIRC) Biorenewable feedstock to replace petroleumbased products. Can we engineer model organisms (yeast) to make more fat? Each group of students designed an experimental investigation to compare fatty acid production of their strain of yeast compared with a parental strain. Promising results sent to CBIRC for follow-up 5 Nov 3, 2014 Student research idea, done in a course Astronomy (30 students) Students used a variety of small telescopes, up to 14inch in size, together with Charged-Coupled-Device (CCD)
imaging. Example projects included Observations of bright stars in two young galactic clusters to determine their respective evolutionary state Determination of properties of the bright stellar population in a nearby galaxy Detection of an extrasolar planet orbiting a star over 450 light years from Earth. 6 Nov 3, 2014 More students engaged in research 1105 student research experiences N=80 N=325 N=180 Meteorology, Astronomy, Genetics, Animal Chemistry Behavior for majors
7 N=470 N=9850 Geology, Organic chemistry Human Physiology Physics, Chemistry, Biology, Geology Nov 3, 2014 How implemented Faculty Learning Community (FLC) meeting for 4 years Plan, support first implementations, adjust, assess impact Larger projects had startup help Education postdoc or graduate student Equipment Operational costs kept ~ as original lab course
Graduate TA learning community Discuss student learning, how to assist with research planning, changes,. Led by postdocs, senior TAs 8 Nov 3, 2014 Assessment: Nature of Science (NOS) Pre Post Observations Creativity Science Cultural Method Influences Idea Social interaction acceptance
Across all courses, no improvement, except creativity 9 SUSSI, Liang et al, 2008 Nov 3, 2014 Assessment: Nature of Science (NOS) Students asked to write/reflect on some topics of NOS moderate improvement Reflection (instructor choice) gain No reflection Social interaction Cultural Idea Science Influences Method acceptance
Observations 10 Creativity Students come to university science with NOS conceptions Nov 3, 2014 that are difficult to substantially alter. Next steps (HHMI 2014-18) Adapt Univ. of Texas, Austin, Freshmen Research Initiative to bring more course-based research into 1st year Spring semester Lab credit ~24 students work on class-wide, linked projects Part of their major, Learning Community Undeclared students (500 each year) Interdisciplinary projects aligned with their declared interests 11
Nov 3, 2014 Conclusion Vision: Every time a student steps into a science classroom, they will be doing/discussing science with their peers Implemented course-based research projects. ~1100 students each year From student-driven extensions of inquiry labs to student generated research idea Faculty Learning Community key to plan, support each other Explicit writing/reflections leads to moderate improved NOS Students come to university science with NOS conceptions that are difficult to substantially alter. Next steps Engage more freshmen and undeclared students 12 Nov 3, 2014 Acknowledgments HHMI grant 2010-2014 Cinzia Cervato, Tom Greenbowe, Jo Anne Powell-Coffman, Gene Takle
