*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.

--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.

Our vision for mobile apps...
http://www.tecca.com/columns/how-to-deal-with-your-partners-gadget-obsession/
* Provide immediate access
* Fun (exciting)
* Sense of accomplishment (productive)
* Social (connected)
* Playful (to encourage curiosity)
![Page 8: ICCE 2014: Valence - An App for Teaching Chemical Bonding](https://reader036.fdocuments.in/reader036/viewer/2022062514/557daf76d8b42acb768b504a/html5/thumbnails/8.jpg)
Our design principles...
* Learning goal centric
* Provide some background
* Test understanding
* Games, play & sharing

Native iOS app - Valence
* Tactile - move electrons to make bonds
* Visual - color coding provides contextual clues
*Audio – music plays with success
*Fun

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.

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

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.

* 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

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)!

These devices coming soon...
