2Educational TechnologyWhat Kind of History?
3Definition?
- Technology is
- cool gadgets and stuff
- Popular usage
- the scientific study of the practical or
industrial arts (Here, education a
practical art?) - Oxford English Dictionary, sense 1.a
- the application of scientific knowledge to the
practical aims of human life - Encyclopedia Britannica
4Possible Approaches-WHAT to Consider
- Devices
- Film projector, computer, chalkboard
- Symbol systems
- Writing, number systems, musical notation
- Theoretically based methods
- Skinnerian programmed instruction, Ausubel
lecture method - Production systems
- Textbook writing and editing
5Possible Approaches-HOW to Consider It
- Devices and their perfection over time
- Heritage of ideas
- Behaviorism
- Cognitive psychology/learning sciences
- Critical theory
- Social anthropology and contexts of use in
particular settings - Policy development and implementation
6DEVICESBooks (manuscript and printed)
- The original technology for education?
- Complexity and expensive production limited
access - Discipline of copying as a moral good
- Mediaeval scriptorium
7DEVICES The Hornbook
- Early aid to basic literacy
- Horn layer student-proof technology
- Reusable, simple production
- 17th century hornbook
8DEVICESEarly Textbooks
- New England Primer (from mid-17th c.)
- Picture-verse combinations aid memory
- Common cultural experience
- Primer from 1784
9DEVICES Wall Charts and Maps
- Mid-19th century (Germany, Netherlands)
- Easy, large-class display
- Better printing technology allows easier
production - Knys botanical charts, ca. 1874
10DEVICESThe Chalkboard
- Most successful educational innovation of the
19th c.? - (And maybe 20th?)
- Ease of use, reusable, user-friendly
- (Except for teacher-back-turned problem)
11DEVICES Clever Combinations
- Chautauqua Desk
- Swiss Army Knife of educational material
- Part of larger movement for self-improvement,
home education - Chautauqua desk, ca. 1916
12DEVICESOverhead Projector
- Really?!? But this thing is so simple
- Yeah, but It spread around US classrooms faster
than any other device - Why?
13SYMBOL SYSTEMSWriting systems
- From 4000 BCE
- Codify knowledge
- Cultural continuity
- Systematize thought
- Papyrus with hieroglyphs
14SYMBOL SYSTEMSInstructional text
- The Thousand Character Classic
- Ca. 520 CE, by Zhou Xingsi
- Explicit instructional design
- Meaning and sound represented
- Calligraphic version
15SYMBOL SYSTEMS Mathematical Representation
- Symbol systems for representing knowledge
- Encoding, operations, etc.
- Reisch, Margarita Philosophica, 1508 Arithmetica
instructing an algorist and an abacist
16SYMBOL SYSTEMS Other Representation Forms
- LABANOTATION
- Represent dance movements, including speed,
direction, lights source, etc. - Cf. musical scores
- Other similar systems for rhythm, etc.
17SYMBOL SYSTEMSFilm and Video
- The Montage (from Sergei Eisensteins Battleship
Potemkin 1925 the Odessa Steps sequence) - All manner of filmic/video devices fades, cuts,
wipes, dissolves had to be invented, and
acquire meaning
18SYMBOL SYSTEMSSo Do They Have Cognitive Effects?
- Orality vs. Literacy debate
- McLuhans theses
- Tufte on PowerPoint, etc.
- Walter Ong
19SYMBOL SYSTEMSGaming
- Narrative, Metaphor, Engagement
- Elicit extended focus
- Complex environments, real learning
- Action and violence
- How to harness the potential for learning?
20THEORETICALLY BASED METHODSSkinnerian Programmed
Instruction
- Skinners behaviorist learning theory
- Wide popularity in late 1950s-1960s
- B o r i n g . . .
21PRODUCTION SYSTEMSTextbook writing, editing,
revision
- From simple book to industrial complex
- Production team model
- Systems for regular revision
- Competition OER movement (cf. Wikibooks, WSBCTC)
22PRODUCTION SYSTEMSClassroom Assessment
- Student data digitized (responses, work samples,
quizzes) - Real-time availability to instructors
- Linkage to other systems (remediation tools, etc.)
23PRODUCTION SYSTEMSSocial Media
- Facebook, YouTube, Wikipedia, Twitter, etc.
- How we communicate and share now
- Multitasking and cognitive load
- This is how I goof off and waste time why would
I want to use it for my education?
24Possible Approaches-HOW to Consider It
- Devices and their perfection over time
- Heritage of ideas
- Behaviorism
- Cognitive psychology/learning sciences
- Critical theory
- Social anthropology and contexts of use in
particular settings - Policy development and implementation
25Our Approach Here ThreefoldView from the Past
- Devices ?
- Emergence of new symbol systems to capitalize on
what those devices make possible ? - Incorporation of those symbol systems into
educational materials, products, experiences ? - Research studies to determine if those materials
(etc.) are effective
26Our Approach HereView from the Present
- Research studies (done in the past) ?
- More contemporary studies or reviews that address
those or related themes ? - Understanding of the contributions of past work
- Knowledge and appreciation
- Extension of existing lines of work
- Avoidance of pitfalls and blind alleys!
27Our Approach HereView towards the Future I
- Changes in theory (Learning sciences focus)
- Learning collaborative, socially embedded
- Context and prior experience matter
(decontextualized knowledge dead knowledge) - How information is represented matters
- Changes in technology
- More pervasive, less special
- Affecting our relationship with text?
28Our Approach HereView towards the Future II
- Changes in education
- Heightened focus on outcomes, assessment
- Less room for open exploration
- More focus on teacher professionalism
- Changes in policy
- Increased global competitiveness pressure
- Pressures to rationalize education (esp. higher
ed)
29What Else?
- Comments, extensions, arguments?
- (Much more to come)
- Thanks!
