  • Device diversity is a challenge.
    Finishing polishing the UI, ensuring it’s intuitive and have good representation of samples. Submitting to Apple review this week.
    Programming - I’ve become a programmer and it’s not my strength...
    Slower download for webapp. Possible bandwidth issues....

    Oh, The challenges...
    Oh, The opportunities....
  • ICCE 2014: Valence - An App for Teaching Chemical Bonding

    1. 1. Valence: An App for Teaching  Chemical Bonding Lisa B. Lewis and Alex M. Clark July 16, 2014
    2. 2. Students and mobile devices in CHEM 121
    3. 3. *A different vision of the way people will access information, learn, amuse themselves and create material with others is emerging. *(Apps are) ubiquitous, powerful, and strongly structured, and Gardner and Davis argue that they’re changing the way we think. “Young people growing up in our time are not only immersed in apps,” they write, “they’ve come to think of the world as an ensemble of apps, to see their lives as a string of ordered apps,…” - Howard Gardner Mobile devices to change education? The Web is Dead. Long Live the Internet, http://www.wired.com/magazine/2010/08/ff_webrip/ & The Future of Apps and Web, http://pewinternet.org/Reports/2012/Future-of-Apps-and-Web.aspx & Is There an App for That? By K. Xue, Harvard Magazine Nov.- Dec. 2013.
    4. 4. --Just-in-time information-- 62% of the entire adult population have used their cell/smartphone within the last 30 days to: *find information to settle an argument, *solve an unexpected problem, *get up-to-the-minute traffic information, *decide on a restaurant, etc. Mobile devices to change education?

    5. 5. http://www.cellphonebeat.com/5-reasons-sleep-ce Mobile devices to change education?
    6. 6. How smartphones make people feel KPCB Internet Trends Report, Meeker and Wu, May 2013. This, not this... http://www.timeshighereducation.co.uk/news/great
    7. 7. Our vision for mobile apps... http://www.tecca.com/columns/h ow-to-deal-with-your-partners- gadget-obsession/ * Provide immediate access * Fun (exciting) * Sense of accomplishment (productive) * Social (connected) * Playful (to encourage curiosity)
    8. 8. Our design principles... * Learning goal centric * Provide some background * Test understanding * Games, play & sharing
    9. 9. Native iOS app - Valence * Tactile - move electrons to make bonds * Visual - color coding provides contextual clues *Audio – music plays with success *Fun
    10. 10. Native iOS app - Valence *Limited narrative * Individual lessons *Increasing complexity * Reflection questions
    11. 11. Native iOS app - ValenceNative iOS app - Valence *Five lessons (levels): main group hydrides multiple bonds small molecules polyatomic ions exceptions to octet rule * Can make mistakes * Individual study or in class
    12. 12. Native iOS app - Valence * Future: Additional lessons Chemical intelligence Built-in analytics Game Center
    13. 13. Assessment of webapps * AcidBase: Understand concept of acid/base strength; Be able to recognize strong acids and bases * Shakespeare Sonnets: To understand the poems meanings and how rhyme and meter impact meaning.
    14. 14. % Correct in  Listing the Strong  Acids, Spring  2012 CHEM 121, section A (had use of AcidBase webapp) Perfect Recognition     CHEM 121, section B (did not have access to AcidBase webapp) Perfect Recognition Surprise Quiz 1 41% (7 of 17) 59% (10 of 17) 25% (6 of 24) 29% (7 of 24) Surprise Quiz 2 67% (12 of 18) 83% (15 of 18) 48% (11 of 23) 65% (15 of 23) Surprise Quiz 3 81% (13 of 16) 88% (14 of 16) 76% (19 of 25) 92% (23 of 25) Assessment results for AcidBase * Students with access to AcidBase mastered recognition of strong acids sooner than those who were not given ready access to the app.
    15. 15. Time on task, as reported by the students Time  CHEM 121  Students  Spent  Using  AcidBase Spring 2012 0 minutes 22.7% (5 of 22) < 5 minutes 13.6% (3 of 22) 5-10 minutes 27.3% (6 of 22) 10-15 minutes 22.7% (5 of 22) 15-30 minutes 13.6% (3 of 22) > 30 minutes 0% (0 of 22)
    16. 16. Using AcidBase in the classroom... *Pre-test. *Brief lecture on acid/base definitions. *Students use AcidBase app in class. *Post-test. Avg. pre-test score = 6.7/12; Avg. post-test score = 9.6/12
    17. 17. Initial Assessment for Valence * My 10 year old daughter, no chemistry experience, plays with Valence for fun! * Completed reflection questions for first two levels. * Successfully pointed to where the lone pair is located on the 3-D model of NH3 & wrote the correct 2-D representations for SiH4 and H2Se.
    18. 18. * Device diversity Valence only for iPad, iPhone and iTouch Browsers read and render webapp code in different ways. * Assessment * Refine, update design Challenges & future efforts
    19. 19. Why consider using these devices in the classroom? 4th Grade Science Fair Project To begin their experiment, they needed magnets, nails, paperclips, a compass, a hammer .... ...and TWO iPods (stopwatch, camera, Google)!
    20. 20. These devices coming soon... KPCB Internet Trends Report, Meeker and Wu, May 2013.
