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

  2. BioQUEST: Biology Quality Undergraduate Educational Simulations & Tools • Consortium of ≈150 active members & ≈5,000 fellow-travelers • Dedicated to Biology Curriculum Reform

  3. BioQUEST Philosophy • 3 Peas: • Problem Posing • Problem Solving • Peer 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

  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

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

  13. 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

  14. 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)

  15. 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

  16. Availability: • BioQUEST Library CD–ROMindiv: $99* ISBN: 0-12-099470-4 Site: $650 U/C* • Macintosh: $350 HS – System 7, System 7.1+ suggested, 4 MB available RAM • Windows: Windows 3.1+, Windows 95 + suggested, 8 MB available RAM. • Both: 180 MB of free hard disk space, color monitor with 800 x 600+ resolution, QuickTime® 3+ to play panorama & sound files.
