Democratizing Bioinformatics Research in a High School Biology Classroom Bertram C. Bruce, Umesh Thakkar, Eric G. Jakobsson, Jo Williamson, Paul R. Lock U. of Illinois at Urbana-Champaign
Bioinformatics • Just as astronomy was transformed through the invention of the optical telescope, and later, the radio telescope, biology is becoming a new science, one which links studies of biochemistry, genetics, cellular processes, anatomy, physiology, and evolution through the structure and properties of macromolecules (Gibas & Jambeck, 2001) • A major tool in this transformation is Biology Workbench (Subramaniam, 1998)
Biology Workbench • Sequence alignment • Visualization • Digital library • New knowledge: potassium channels; compare sequences from various cells, tissues, & organisms; insights into the structural correlates of ionic selectivity, permeability regulation, toxin sensitivity • Available since June 1996 • 11,000 registered users; 150,000 computing sessions a month
Alignment of Sequences from Horse, Chicken, Cow, Vulture, Dogfish, Tuna, Mole
Open-World Learning • open data and problems • open computational environment • open community
Mr. Lock’s information Ecology • University connections • Projects in which “students have to … [find] things that really aren’t covered in the book.” • Students have access to technologies that professional scientists use everyday in their work. • Collaborative learning • Articulation of learning
Inquiry-Based Learning learning tools that are "open-ended, inquiry-based, group/teamwork-oriented, and relevant to professional career requirements” National Science Foundation (1998). Information Technology: Its impact on undergraduate education in science, mathematics, engineering, and technology. Arlington, VA: National Science Foundation.
Inquiry Unit • Ask: How are different organisms related? How can we show their evolutionary history? • Investigate: Identify the evolutionary history of a group of organisms through protein sequence analysis. • Create: Show how similar organisms are related using phylogenic trees (cladistic diagrams) . • Discuss: Present findings in a poster session. • Reflect: Examine the learning process.
Chain of Use • The teacher educator needs to understand and value the technology • Education students need to be able to use and learn from the technology • The education student/teacher needs to take it from the college classroom to the school • High school biology students need to be able to use and learn from the technology
Conclusion • challenge of integrating into educational system • students part of a larger community of inquiry • eliding distinctions between • practice/research • student/teacher • learner/researcher • learning/research
