  1. The Virtual Cell Project Phillip McClean Alan White Brian Slator North Dakota State University

  2. Educational Role-playing Games“Learning-by-doing” Experiences • MultiUser • Exploration • Spatially-oriented virtual worlds • Practical planning and decision making

  3. Educational Role-playing Games“Learning-by-doing” Experiences • Problem solving • Scientific method • Real-world content • Mature thinking

  4. Advantages of Virtual Worlds • Collapse virtual time and distance • Allow physical or practical impossibilities • Participate from anywhere • Interact with other users, virtual artifacts, and software agents • Multi-user collaborations and competitive play

  5. Technical Approaches • Networked, internet-based, client-server • MultiPlayer • Simulation-based • Implemented in Java applets

  6. The VCell VRML Worlds The Cell The Laboratory

  7. The Virtual Cell

  8. The Laboratory

  9. Details of the VCell • Interface • Game Play

  10. VCell Login Use VCell login box to connect to the cell The VCell VRML file will load in the Client Window.

  11. VCell Instructions Reference information about organelles, etc. is available here. Goals for each level are listed here Instructions from Lab Guy

  12. Transporting from One Place to Another Click on the Lab Guy icon to move between the Laboratory and the VCell. The Do It Box gives you choices for destinations. For example, this selection will send you to the VCell for your next set of experiments.

  13. Performing Experiments Fly around organelles and perform experiments Choose actions here Choose assays here Experimental Results

  14. Deduction of Organelle Identity Choose Identify action here Choose organelle to identify here Successful identification based on experimental results

  15. Achieving Another Goal Information for new goal New Action and Assay Experimental Results

  16. Completing Another Goal Updated Goals Success again!

  17. Guessing Not Allowed Appropriate experiments required for identification.

  18. All Goals Completed Directions for proceeding to the next level given.

  19. ETC Exercise Instruction Window You arrive in the Lab. Click on the Lab Guy to receive your next instructions. Lab Guy welcomes you back and gives you your next assignment

  20. Mitochondrial Function: Electron Transport Chain Animation ETC Membrane Complexes Molecules in motion Molecule Key http://www.ndsu.nodak.edu/ndsu/abergstr/vcell/rox/july27/600p4c.wrl

  21. Chloroplast Function: Work in Progress User in Sub shoots photons to activate photosynthesis Photosystem Complexes

  22. Assessment • Not “multiple choice” recall • Content specific: • Problem solving, hypothesis formation, deductive reasoning

  23. Assessment by Scenarios • Assess computer literacy • PreTest: Present scenario, students propose course of action or solution • Engage in learning experience Control vs Virtual • PostTest: Present similar scenario, student response • Analysis of assessment data

  24. Current Implementation NDSU General Biology Class 600 students total 300 control students 150 alternative (WWW based, but not VCell) students 150 VCell students
