Presentation given at International Conference on Chemical Education, July 2014. Previews Valence, a new app for teaching chemical bonding, and discusses motivation behind project to develop apps for teaching chemistry.
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 theyâre
changing the way we think. âYoung people growing up
in our time are not only immersed in apps,â they write,
âtheyâve come to think of the world as an ensemble of
apps, to see their lives as a string of ordered apps,âŠâ
- 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,

Dec. 2013.
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.

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. Our design principles...
* Learning goal centric
* Provide some background
* Test understanding
* Games, play & sharing
9. Native iOS app - Valence
* Tactile - move electrons to make
bonds
* Visual - color coding provides
contextual clues
*Audio â music plays with success
*Fun
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. Native iOS app - Valence
* Future:
Additional lessons
Chemical intelligence
Built-in analytics
Game Center
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.

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.

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. 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. * 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. 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. These devices coming soon...

Device diversity is a challenge.
Finishing polishing the UI, ensuring itâs intuitive and have good representation of samples. Submitting to Apple review this week.
Programming - Iâve become a programmer and itâs not my strength...
Slower download for webapp. Possible bandwidth issues....
[DRAMA]
Oh, The challenges...
Oh, The opportunities....
