1 BioQUEST Evolution Modules Frank Price Scholar in Residence, Hamilton College (315) 853–5233 in collaboration with other members of the BioQUEST Curriculum Consortium

2 BioQUEST: Bio logy Q uality U ndergraduate E ducational S imulations & T ools Consortium of ≈150 active members & ≈5,000 fellow-travelers Dedicated to Biology Curriculum Reform

3 BioQUEST Philosophy 3 Peas: –P roblem Posing –P roblem Solving –P eer Persuasion Students need to do what professionals do: –Ask their own questions. –Find appropriate data. –Analyze data with appropriate professional tools. –Answer their questions. –Persuade peers of the value of their answers. They need opportunities to work in the context of the discipline

4 BioQUEST Philosophy Inquiry–oriented approach –Goals, assumptions, models, history become explicit –Promote interpretation of data –Effect-to-cause reasoning –Encourages multivariate approaches Encourage collaboration –Advantages of collaborative learning –Multiple modes of learning, –Multiple skills De-emphasize “content” relative to skills Emphasize Information Technology as a tool –Supplement, not replace, actual lab/field work

5 BioQUEST Funding Active –Howard Hughes Medical Institute, –National Science Foundation*, Division of Undergraduate Education –Partnership for Advanced Computing Infrastructure Previous : – Annenberg/CPB – Foundation for Microbiology – Beloit College – University of Chicago – Center for Biology Education, UW - Madison – Apple Computer – Pew Midstates Science & Mathematics Consortium * 24 Funded NSF grants cite BioQUEST Library resources

6 BioQUEST Modules: Disciplines Background & Pedagogy Behavior Biomathematics Botany Cell Biology Development Ecology EvolutionEvolution General Biology Genetics Microbiology Molecular Biology Molecular Visualization Mycology Zoology Physiology Statistics Tools Zoology

7 The Problems With Evolution Educaton: Evolution is widely misunderstood – We don’t teach it well Lack of Labs – Time and space – Variety of data & methods – Pedagogical models Lack of Data

8 Key Pedagogical Points: Goals for Students Understanding of products of evolutionary biology (state of the art) –Theory –History Learn assumptions that frame thinking Practice methods

9 Key Pedagogical Points: Evolutionary Biology Goals of Evolutionary Inquiry –Theory: models of processes/phenomena –History: phylogenies as historical hypotheses Shared assumptions, e.g.: –Species as gene pool w/ genetic variation –New variation continuous, random –Evolution: statistical change of population –Historical contingency Methodologies & Tools –Various

10 BioQUEST Modules: Evolution BIRDD Data Library(Mac, Win) EVOLVE Simulation: microevolution(Mac) Biology Student Workbench Analytical tool(Mac, Win) MacClade 2.1 Analytical tool(Mac) Phylogenetic Investigator Instructional tool(Mac) BeeVisit Simulation: pollination (Win) BGuILE: Galapagos Finches Simulation: ecology, selection(Mac) BGuILE: TB Lab Simulation : antibiotic selection(Mac) Bumpus Numeric Dataset(Mac, Win) Caminicules Visual dataset (Mac, Win) Dendrograminaceae Visual dataset (Mac, Win)

11 On–Line Info: BioQUEST Curriculum Consortium: BioQUEST Liberary purchase: (Academic Press)


13 Our Solution: BIRDD Digital library of raw data: – Realistic – Accessible – Exportable Open – ended Instructional Support : – Getting Started – Classroom Examples – Teaching Evolutionary Biology

14 Opportunities For students –Senior Projects –Database development (possible summer stipend) –Student teaching For faculty –Material for labs Evolution, Ecology, Intro. Biol., animal morphology, Statistics, etc. –Opportunities for student projects In courses Database development –“Publish” your data

15 BIRDD Has Been Tested At: Beloit College (small, liberal arts): –Zoology: non–major’s intro. (Paul Whittaker) –Biological Issues, Making Sense of Evolutionary Explanations: non–major’s (Sam Donovan) –Evolution: major’s (John Jungck) U. WI, Madison –Introductory Zoology: major’s intro., > 800 students/semester (Jean Heitz)

16 Jean Heitz’ Approach to Using BIRDD: Grant Proposals ( Used in Introductory Zoology, UWI, Madison) Week 1: –Acquaint students w/ BIRDD, Galapagos, finches –Find some preliminary questions Week 2: –Present ideas to whole lab for critique –Revise, develop preliminary answers –More thorough analysis of data, Week 3: –Present 2nd proposal draft to whole lab for critique –Write final propsal Week 4: Turn in proposal
