Presentation Transcript

  1. Bioinformatics in Motion Steffen Heber, NCSU Leif Saul, CU-Boulder

  2. Overview • Background about Animations • The Bioinformatics in Motion Project • Conclusions and Future Developments

  3. Educational Animations are Popular! Algorithm animation in Computer Science

  4. Other Life Science Animations • Biology in motion [http://biologyinmotion.com/] • Biology Animation Library [http://www.dnalc.org/ddnalc/resources/animations.html] • HHMI’s Biointeractive – Virtual Labs [http://www.hhmi.org/biointeractive/vlabs/] • Science Animations, Movies & Interactive Tutorial Links [http://science.nhmccd.edu/BioL/animatio.htm] • Geospiza, Inc. Education [http://www.geospiza.com/outreach/] • Virtual Cell Animation Collection [http://vcell.ndsu.nodak.edu/animations/] • DNA Microarray Methodology – Flash Animation [http://www.bio.davidson.edu/Courses/genomics/chip/chip.html] • Also, often used in software demos, tutorials, and webinars

  5. Common Knowledge? Educational Animations can … • directly show changes in form, position, and time • increase student interest and motivation • help students to understand and remember information

  6. Student Response Positive answer 25 Indifferent 1 Negative answer 1 Did not respond 2 Do you feel that algorithm visualization/animationhelped you to learn how algorithms work? • “I used them to study for the final” • “yes, to practice how the algorithm works” • “it helped me to understand, and stay awake” • “they helped to make the lecture interesting” • “fun stuff!” • “probably not, too time consuming”

  7. Are Animations Effective? Just watching does not improve learning

  8. How We Learn from Animations • Two main information processing channels:visual and auditory • Learning = active processing in memory • Limited capacity for info processing

  9. What Makes a “Good” Animation? Use research based design principles: • Present animation and narration simultaneously • Avoid identical streams of printed and spoken words • Use narration in conversational style • Focus on interactive activities

  10. Bioinformatics in Motion Develop Flash Animation Modules for undergraduate students. Topics: • Sequence Alignment • Motif Finding/Discovery • Database Search: BLAST • Genome Rearrangements • Fragment Assembly • Hidden Markov Models Animations:http://statgen.ncsu.edu/slse/animations/

  11. Workflow • Text storyboard • Illustrated with static Flash images • Images developed into animations A similar approach as used by PIXAR

  12. Why Flash? • Flash - Benefits include: • Small file size • Plug-in widely distributed • Object-oriented programming (Actionscript 3)‏ • Visual authoring tools • Animated programmatically • Static images placed on stage • Transitions encoded in XML • Animations generated at runtime

  13. Project Features • Static images • Cartoons / metaphors • Animations • Spoken narration • Interactivity • User controls delivery • Instructor controls delivery

  14. Project Features • Static images • Cartoons / metaphors • Animations • Spoken narration • Interactivity • User controls delivery • Instructor controls delivery • Other resources

  15. User Controls Delivery • Playback controls • Voice vs. text narration • “Liquid” interface adjusts to screen size • User feedback Please send us feedback!

  16. Types of Animation Used • Changes in size, position, etc. • Cartoons / metaphors • Visual effects / enhancements • Computed

  17. Types of Interactivity Used • Quiz • Exploration / experiment • Game-like (user seeks an optimum)‏

  18. Some Design Dilemmas • Continuous “movie” vs. chunks? • Movie: Inviting, easy experience • Chunks: User can choose • How much narration per step? • Too much: User less in control • Too little: User gets “click” fatigue

  19. Conclusions: Animations … • are fun! • they increase attention and enthusiasm • address different learning styles • support teachers, distance education & independent student learning • work best if interactive • in Flash are time-consuming to develop

  20. Future Areas of Development • What material is best taught via animations? • How to package and integrate animations into class/html documents? • Can animations adapt to different student needs?
