Educational Technology Past • The “streams” or “threads” that comprise ET Computing/ Calculating Media Instructional Design Educational Technology
Educational Technology Past • Educational Technology is at the nexus of Psychology, Media, and Computer Science • With the exception of a brief flurry of design activity around programmed instruction, the focus from the educational community and society has been on technology and its promise to solve educational problems…
In Other Words… Technology is The Answer!!! …but what was the question?
Why should we care about history? • "All this has happened before. All this will happen again.”
Educational Technology Past • Beginning in 1850 with the invention of the “Magic Lantern” (flame produced light and transparent slides), the educational value of media has been proclaimed.
Educational Technology Past • With motion pictures, recorded sound, “talkies”, etc. it appeared that books, and teachers(!) would become obsolete • “…books will soon be obsolete in schools. It is possible to teach every branch of human knowledge with the motion picture.” (Thomas Edison, 1913)
Educational Technology Past • Then radio would save education, then television… • “Radio broadcast is one of the greatest educational tools which has ever been placed at the disposal of civilized man.” (G.T. Buswell, 1935 - The Phi Delta Kappan)
Educational Technology Past “The results of the studies outlined above give substantial evidence that television does an adequate, and perhaps superior, job of teaching” (Williams, The School Review, 1956)
Educational Technology Past • Video discs • Personal computers • Tablet computers • Mobile devices • The next innovation…
Educational Technology Present • In U.S., IT spending in education reached $47.7 billion by the end of 2008 and is exceeded $56 billion by 2012. • According to “Education Snapshot: Learning with Technology,” most education IT spending is occurring in higher education–about 64% versus 36% in K-12. (Nagel, THE Journal, 2008)
Educational Technology Present • Over 60% of the funding is in telecommunications, wireless, security, etc. (hardware and personnel). • The rest is what pays for computers and other technology and software.
Educational Technology Present • Distance learning in K- 12 and Higher Education • Virtual Worlds • Games • Tablets & iPads • MOOCs • Flipped classrooms
Educational Technology Research • Lots of money, time, and effort • Does it work? • What do we even mean when we ask “does it work?” • Research vs. Evaluation
Research Began Early • As audio-visual innovations emerged, each was “researched” by comparing it to “traditional” instruction • Known as media comparison studies • Distance education produced some of the first documented studies in ET
The Problem with Comparisons • Lack theoretical basis • Confounding variables • Most result in “no significant difference” outcomes • Hundreds of studies over decades of research • Every innovation becomes focus of comparison • Even meta-analyses of NSD studies
However… GI = GO
To make matters worse… • NSD results are misinterpreted to mean “as good as” • This causal leap was unjustified, only indicating the treatment had no effect • Analyses revealed confounding variables of media features and instructional strategy
So What Are Good Questions? • Micro level issues • Media attributes • Instructional strategies • Learner characteristics • Macro level issues • Analysis & design of systems • Exploration of contextual factors • Examination of socio-cultural issues
3M’s of Technology Mediated Learning • Delivery Mode • Media attribute • Instructional Method
Realism and Abstraction • Amount of detail • Line drawings--photographs--3-D • Realism can cause interference • Color vs. Black & White • No difference in learning • Preferred by learners • Color can provide visual cues
Media Attributes • Motion • Sequence • Interaction/Communication • Feedback
Instructional Strategies • Demonstration • Problem-based learning • Collaborative strategies • Individualized instruction
Learner Characteristics • Cognitive style • Motivation • Self-efficacy • Cultural influences
Two Examples Starting a skip loader grader Personal protective equipment
Current Research Trends • Movement from lab to applied settings • From single method to mixed approaches • Design-based research • Iterative process of manipulating variables in the learning environment until it “works” • Nelson, W. (2013). Design, research, and design research: Synergies and contradictions. Educational Technology (53), 1, 3-11.
The Design Process Analyze Design Develop Implement Evaluate
Synchronous Distributed Systems Conferencing Systems • Features • Supports real-time communication for learning • Various modalities • Low development overhead • What the Evidence Says • Can be very effective in support of outcomes related to procedural knowledge or social interaction skills • Instructor and student preferences related to social presence • Some negative feedback from learners regarding “being on the spot”, hesitance to participate
Synchronous Distributed Systems Multi-Player Games • Features • Social interaction • Competition and collaboration • Rules and goals • Players take on roles, can be team-based or individual • Environments can vary from simplistic graphics to virtual reality • What the Evidence Says • Game accessibility and ease of use is critical to learning • Not great for direct instruction, action is emergent and focused on interactions and player choices • More appropriate for open-ended learning, gaining insights, triggering questions • Debriefing upon completion can provide important feedback for both instructor and students
Synchronous Distributed Systems Augmented Reality Systems: mediated view of real world environment enhanced with digital information • Features • Information can be displayed through a variety of technologies including head-mounted displays, handheld devices (including smartphones & iPads), and spatial, projected displays • Can support a variety of tasks including mechanical processes, navigation, surgery, military exercises, language translation • Can support individual instructional activities or collaborative endeavors • Digital enhancements are possible through a variety of media, including text, video, graphics, etc. • What the Evidence Says • Engagement and motivation of learners with prior challenges related to behavior and participation • Development of distributed knowledge and positive interdependence • Some learners experience cognitive overload • Can be remedied with effective design decisions
Asynchronous Distributed Systems Asynchronous E-Learning • Features • Flexibility in time and pace of coursework completion • Depending on delivery system, can support wide range of media features (text, audio, video, animations, etc.) • High overhead in initial development, but payoff related to ease of modifications and maintenance • What the Evidence Says • Learners appreciate independence and convenience • Struggles with completion and attrition • Can be remedied with firm deadlines and regular communication from instructor • Some negative perspectives related to perceived decreased social presence • Can be addressed with provision of feedback and communication flow
Asynchronous Distributed Systems Adaptive Learning Systems: computer-based instruction, content based on student input and performance • Features • Individualized instruction • Customized to learner needs • Mastery-learning • Can support variety of delivery modes and media features • What the Evidence Says • Can enhance learner performance, as instruction is targeted to specific needs • Heavy front-end design needs can present barriers • Evaluated through comparison conditions, demonstrate system effectiveness
Asynchronous Distributed Systems Mobile Learning: the use of mobile technologies to deliver instruction • Features • Supports a variety of content and instructional approaches • Often used to provide scaffolded support in field work or clinical instruction • Can capture and deliver learner information in many forms (text, photos, voice) • Device variance can be problematic • Internet access necessary • Can use a variety of media features, but small display and text input can pose challenges • What the Evidence Says • Content should be delivered in simplest possible form • Same issues of procrastination as e-Learning, can be addressed through pushed email reminders, phone communication, quizzes and questions • Learner preferences indicate an appreciation for flexibility. When compared to standard e-Learning, learners preferred non-mobile option.
The Next Generation? • Believing…more of the same? • US DOE 2010 National Ed Technology Plan • “Identify and validate design principles for efficient and effective online learning systems and combined online and offline learning systems that produce content expertise and competencies equal to or better than those produced by the best conventional instruction in half the time at half the cost.”
The Next Generation? • Believing…more of the same? • “Design and validate an integrated system that provides real-time access to learning experiences tuned to the levels of difficulty and assistance that optimize learning for all learners and that incorporates self-improving features that enable it to become increasingly effective through interaction with learners.” • Personalized Learning Environments • Sound familiar??
The Next Generation? • Hoping… • Research related to technological innovations and systems to engage learners • Increase interest in and excitement about learning • Virtual humans to engage learners in science • Access information through innovation attributes • Augmented reality to teach history
The Next Generation? • Hoping… • To echo Tom Reeves call for more “socially responsible research” • Technology-enhanced learning environments to address real world problems • Preserving language and culture • Distance education to develop human capacity • Using game-based instruction to increase girls’ awareness of IT careers
The Next Generation? • In closing, let’s be hopeful that… • Instructional technology research will • be informed by the past • explore meaningful issues that address real world problems • Make a difference in the future!
