Using Visualizations in Remote Online Labs - Talk at CyTSE

  1. 1. Using Visualizations in Remote Online Labs <br />Megan Sauter<br />Northwestern University<br />Research in collaboration with <br />KemiJona, David Uttal, and David Rapp, Northwestern University<br />
  2. 2. How do we best represent science labs using today’s technology?<br />
  3. 3. Questions<br />1. How does the type of technology influence the psychological experience of doing a science lab?<br />Remote Labs & Simulations<br />
  4. 4. Questions<br />1. How does the type of technology influence the psychological experience of doing a science lab?<br />Remote Labs & Simulations<br />2. Do the types of visualizations included in the lab change the overall experience?<br />Photos & Webcams (within remote labs)<br />
  5. 5. Ilabcentral.org<br />
  6. 6.
  7. 7.
  8. 8. Procedure and some of our dependent measures…<br />
  9. 9. How does the type of technology influence the psychological experience of doing a science lab?<br />Simulation Remote Lab<br />Data Source: Computer model<br />(lab not linked to equipment)<br />Data Source: Geiger counter <br />(lab linked to real equipment)<br />Interfaces are identical! Only thing manipulated is source of data.<br />
  10. 10. Dependent measures<br />Presence – overall immersion/authenticity of the lab<br />Mental Models – how the lab fits with concepts of science labs<br />Learning Outcomes – conceptual change related to the content and process<br />
  11. 11. Measures of Presence<br />“Did you feel like you just did an experiment?”<br />“Did you trust your data?”<br />“Would you want to run the experiment again?”<br />
  12. 12. Presence<br />
  13. 13. Why did a Remote Lab feel like an experiment?<br />“Even though I’m not with the actual instruments, I designed an experiment and got results and interpreted them and answered a question.”<br />
  14. 14. Mental Models<br />In progress! Selected questions…<br />“Which would you prefer, between a remote lab and a simulation?” <br />“Would you run your lab again in the other condition?”<br />
  15. 15. Mental Models<br />Majority in both labs choose remote lab, but there is a main effect of condition (chi square = 8.074, p <.05)<br />Preference<br />
  16. 16. Why choose a remote lab?<br />Sense of control, sense of reality… overall presence.<br />“Because the experiment is actually happening. Something real is being measured.”<br />
  17. 17. Mental Models<br />Those who did a remote lab would not want to run a simulation multiple times, but those who ran a simulation would want to run a remote lab multiple times (chi square = 18.58, p <.001)<br />Run again?<br />
  18. 18. Learning Outcomes<br />Content understanding<br />What is radiation?<br />What are some of the different types of radiation? Explain why these types of radiation are different.<br />What is radioactive decay, and how does it work?<br />How can you measure radioactivity?<br /> Does the intensity of radiation change over time and distance? <br />Behavioral data from the lab (e.g., # trials)<br />
  19. 19. Learning Outcomes<br />Learning occurs in both versions of the lab (simulation and remote)<br />One difference in behavioral data (# trials), likely due to real-world constraints of Remote Lab.<br />
  20. 20. Do the types of visualizations included in the lab change the overall experience?<br />Photo Webcam<br />Clock moves<br />Counter moves<br />Numbers Change<br />
  21. 21.
  22. 22. Presence<br />
  23. 23. Belief in Equipment and Presence<br />Webcam group: <br /> more variance explained by association between belief in equipment and feeling like you did an experiment, r = .52<br />Photo group:<br /> less variance explained, <br />r = .33<br />
  24. 24. Belief in Equipment and Presence<br />Webcam group: 56% of believers (9/16) spontaneously mention webcam.<br />Photo group: 25% of believers (3/12) spontaneously mentions photo. One participant says webcam would be better<br />Bottom Line: People can usually find a way to believe… but the more realistic the visualizations, the more control over the experience!<br />
  25. 25. Webcam & Presence<br />“Seeing it on video and just like especially the clock just brought a reality to it, where it was digital things on my side and real things on the other side, but I liked it."<br />
  26. 26. An emerging picture…<br />Although learning is robust in both remote labs and simulations, the experience is qualitatively different.<br />Remote lab users more likely to feel like they have done a real experiment.<br />Most participants view the simulation and remote lab as qualitatively different, and attribute important experimental qualities to the remote lab.<br />
  27. 27. An emerging picture…<br />The visualizations used in the lab can influence the experience, favoring webcams over still photos.<br />Webcam viewers more likely to want to run the lab again.<br />Participants thought the webcam was more helpful at convincing them the lab was real.<br />
  28. 28. Take-home Message<br />Students can learn from science labs done on computers… but technology and visualizations that bring reality closer to the student lead to more authentic lab experiences.<br />
  29. 29. Thanks!<br />KemiJona<br />David Uttal<br />David Rapp<br />Michael Downing <br />Eleanor Tushman<br />Kate Bailey <br />Nadeeka Dias<br />Colin Sheaff<br />RicaroseRoque<br />Julia Skolnik<br />Steve Franconeri<br />Contact Information: megan.sauter@gmail.com<br />
