  1. Evaluating Media Characteristics Using multimedia to achieve learning outcomes

  2. Definition • A means of effecting or conveying something • A channel of communication • A condition/environment permitting something to flourish

  3. Overview • Text • Audio • Visuals • Video • Software • Live/F2F • Collaborative • Integration

  4. Positives: Surveyable Easy to produce Low bandwidth Familiar Many readers Not much specialization Negatives: Overused Passive 100% learner motivation Time lag Role of Text

  5. Text Our experience • Paper and digital • Manuals • Chat, discussion • Learning materials • Knowledge sharing – i.e. “blogging”

  6. Text Learning outcomes • Simple to complex • Suited to synthesis/evaluation • Reflection – due to time lag

  7. Positives: Two-way interaction Enrich a text only course Useful for explanations, accessibility, pronunciations Great for auditory learners Speed – faster than typing (and less inhibitive) Negatives: Easy to tune out Text read – limits pace – user needs to be able to disable Need professional “voice” Extended audio needs to be indexed – time/expense Role of Audio

  8. Audio Our experience • VoIP – PalTalk, Groove • Polycom • Audio pronunciations

  9. Audio Learning outcomes • Across spectrum • Presentation • Explanations • Dialogue • Analysis • Synthesis

  10. Positives: Abundance Low cost (if using clipart/digital camera) Versatile – use for any learning task Low bandwidth (if done right) Enrich learning material Negatives: Can be poor quality Motion/animation can be expensive Time consuming Involved if using graphic artist Role of Visuals

  11. Visuals Our experience • Digital pictures • Graphics – Internet • Graphic artist – designing • Enriches text – “picture is worth a thousand words” • Animations

  12. Visuals Learning outcomes • Knowledge • Comprehension • Explanations • Demonstrations • Conceptualizing abstract concepts • Contrasting

  13. Positives: Visual Personal medium Many viewers/large audience Detail complex tasks Ability to review Increased variety – CD, Streaming Negatives: Specialized team – i.e. producer, editor, camera Expensive Not easy to modify Sequential, difficult to survey Passive Role of Video

  14. Video Our experience • Culinary Arts – 7 Courses • Build sets, editing, reviewing • Interruptions in “live taping” • Instructor time commitment • CD ROM • Streaming – 3 month course

  15. Video Learning outcomes • Demonstrations • Explanations • Lecture • Complex – i.e. whiteboard – physics problem solving • Two way (expensive) – instructor observes student

  16. Positives: Simulation Self-paced Re-usable Team based Memorable Game-like – “edutainment” Negatives: Expensive Time consuming Complex to design Team based Added complexity for learners Software

  17. Software Our experience • HTML, Java, Flash, Authorware, Hot Potatoes, LMS (TLM & WebCT) • Simulations • Guided lessons • Always multi-discipline project • Student response - excellent

  18. Software Learning outcomes • Demonstrations • Knowledge • Broad knowledge • Practice complex skill in safe environment • Synthesis

  19. Positives: Highly interactive Familiar – students and instructors Effective Proven history Can incorporate other media Negatives: Only synchronous Expensive No “knowledge” trail Limited audience size Not surveyable Live/F2F

  20. Live/F2F Our experience • Classrooms • Lecture theatres • Hey…we’re college instructors…what more can we say!

  21. Live/F2F Learning outcomes • Everything • Main determinant of success is the skill of the instructor

  22. Positives: Knowledge building Communities Student to student Time on task Ideal for online environment Supplements other media Negatives: Takes time – not ideal for short-course training Difficult to do Change required of student and instructor Collaboration:(As a media format)

  23. Collaborative Our experience • Groove • Communityzero • Slow social acceptance • Too unfamiliar • Much rather talk about it than do it…over-hyped, under done • Control is dispersed to everyone

  24. Collaborative Learning outcomes • Explanation/demonstration • Higher order • Synthesis, evaluation • Deep learning, not surface • Multiple perspectives

  25. Positives: Combine best features, minimize weaknesses Enriched learning Asynchronous Synchronous Negatives: Instructors have to combine tools to achieve outcomes “Ideal” elearning tool doesn’t exist yet Integration Media Integration
