8. + Decision Maker/IT Specialist Jenifer Davis-Lucas Mrs.
Lucas is the media specialist for Franklin Middle School. She is
also the campus instructional technologist. She works with
stakeholders to investigate, purchase, and deploy technologies for
use in the classroom. She also works directly with teachers to help
them effectively integrate the new technologies in their
classes.
9. + End Users Sherry Beck Mrs. Beck is an experienced English
III teacher at Mabank High School. She has seen the introduction,
rise, and decline of many educational technologies over her tenure.
Amanda Perry-Smith Mrs. Smith is a Spanish teacher with three years
of experience. She used much educational technology while in school
and uses this experience with tools to enhance her
instruction.

12. + Module 3 Evolutionary Technologies and Rhymes of
History
13. +Evolutionary technologies:From episcopes to overhead
projectorsRefining technologies of the pastEpiscope or opaque
projectorIs the idea of evolutionary technologies useful in
describing projectorsemergenceTo see more episcopes and opaque
projectors:http://www.luikerwaal.com/newframe_uk.htm?/epidia_uk.htm
14. +Evolutionary technologies:Overhead projectorsOverhead
technology refined into LCD projectorIs idea of evolutionary
technologies useful in describing projectorsobsolescence
15. +Evolutionary technologies:LCD projectorsUseful in
describing projectors obsolescence and emergence of
LCDprojectorsLCD offers more features and ability to show greater
types of media
16. +Rhymes of history:Emergence of overhead
projectorsDemonstration while teachingWithout projection devices,
teachers relied on imaginationNeed to show larger audiences
projected materialRhymes of history are useful in projectors
emergence
17. +Rhymes of history:Obsolescence of overhead projectorsNot
useful in describing projectors obsolescencDemonstrative teaching
has been around for a whileTeachers use many devices to demonstrate
concepts and still includeoverhead projectors if they have not
received LCD machines
18. +Rhymes of history:Emergence of LCD projectorsNot really
useful in describing in LCD projectors emergenceEnhanced features
does not equate to rhymes of historyMultimedia learning theory
enhanced; still could be accomplished with otherA/V tools
19. + Module 4 Six Forces
20. +Disruptive technologies:Emergence of overhead
projectorsUseful in projectors emergenceTransparency filmAbility to
write more comfortablyLess time spent writing class after
class
21. +Disruptive technologies:Obsolescence of overhead
projectorsNot really useful in describing projectors
obsolescenceLCD devices could still be used in classes in
conjunction with other tools
22. +Disruptive technologies:Emergence of LCD projectorsUseful
in describing LCD projectors emergenceLCD technology helped replace
less-reliable CRTSimilar to what happened with televisions
23. +Science fiction:Emergence of overhead projectorsNot useful
in explaining projectors emergenceMight have helped with emergence
of science fictionsPhantasmagoria
24. +Science fiction:Obsolescence of overhead projectorsNot
useful in projectors demiseProjectors were around well before
science fictionScience fiction models like holoprojectors have not
fully emerged
25. +Science fiction:Emergence of LCD projectorsLike overheads,
science fiction does not help explain emergence of
LCDprojectorsScience fiction could pave way for future innovations
like holo-projectorsand handheld projectors being developed.
26. + Module 5 Six Forces
27. +Increasing returns:Emergence of overhead projectorsUseful
in describing projectors emergenceGreater variety of mediaColor in
presentationsAbility to write normally, not large text on
chalkboards
28. +Increasing returns:Obsolescence of overhead projectorsNot
really useful in describing in projectors obsolescenceCRT was
another technology available but it was bulky and expensiveVast
time difference between overhead emergence and LCD projectors
29. +Increasing returns:Emergence of LCD projectorsUseful in
describing LCD projectors emergenceDigital Light Processing (DLP)
vs. LCD projection devicesDLP offered greater features, but LCD
eventually emergedDLP was more bulky
30. +Red queens:Emergence of overhead projectorsNot useful in
describing overhead projectors emergenceDecades of the same
technologyOnly minor improvements over the years
31. +Red queens:Obsolescence of overhead projectorsUseful in
describing projectors obsolescenceLCD manufacturers competing for
market sharePrices dropping dramatically for devices
32. +Red queens:Emergence of LCD projectorsNot useful in LCD
projectors emergenceSlow development cycleNo real competitive
forces driving innovation
33. + The future of LCD Projectors Whats next? Tablet Computers
LED Displays Holoprojection
