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
