    1 : Computers in Medical Education
    2 : Roles of computers in medical education Provide facts and information Teach strategies for applying knowledge appropriately in medical situations Encourage the development of lifelong learning skills
    3 : Goals Students must learn about physiological processes Must understand the relationship between observed illnesses and underlying processes Must learn to perform medical procedures Must understand the effects of interventions on health outcomes
    4 : Basic curriculum Premedical requirements Medical school Basic Physiology Pathophysiology Clinical Residency CME
    5 : Teaching strategies Lecture Interactive Classroom Socratic Problem based learning Bedside See one, do one, teach one Explicit teaching
    6 : Process Presentation of a situation or body of facts containing core knowledge Explanation of important concepts and relationships How does one derive the concepts Why they are important Strategy for guiding interaction with the patient
    7 : Weaknesses of traditional approach Rapid knowledge growth Reliance on memorization rather than problem solving Reliance on lecture method Passive recipients vs active
    8 :

    10 :
    11 : Terms Computer assisted learning Computer based education Computer assisted instruction
    12 : Advantages of computers in medical education Computer can augment, enhance or replace traditional teaching methods Rapid access to body of information Data Images Immersive interfaces Any time, any place, any pace Simulated clinical situation
    13 : Advantages Interactive learning Active vs. passive solving Immediate student specific feedback Correct vs. incorrect, tailored response Tailored instruction Focus on areas of weakness Request help in interpretation
    14 : Advantages Objective testing Permits standardized testing Self-evaluation Fun!
    15 : Experimentation Safe exploration of what-if in a well done scenario You can do things with simulated patients you can’t do with real ones
    16 : Case variety The ability to experience disease scenarios one otherwise wouldn’t see Simple: diabetes Complex: multiple disease, multiple medications
    17 : Time Manage diseases as they evolve over time Rapidly evolving problems Chronic diseases
    18 : Problem-solving competency Book smart vs. real-world Memorization vs. thinking Testing Right answer vs. cost-effective vs. safest vs.quickest (fewest steps)
    19 : Board examinations USMLE test CME testing
    20 : History of CAI Pioneering research in the 1960’s Ohio State Tutorial evaluation system Constructed choice, T/F, multiple choice, matching or ranking questions Immediate response evaluation Positive feedback Corrective rerouting Authoring language
    21 : History Barnett MGH 1970 Simulated patient encounters 30 simulated cases Mathematical modeling of physiology Warfarin, insulin, Marshall Dxplain
    22 : History University of Illinois Computer aided simulation of the patient encounter Computer as patient Natural language encounter
    23 :
    24 : History Illinois 1970’s Programmed logic for automated teaching (PLATO) Plasma display (required specialized equipment) Combination of text, graphics and photos TUTOR authoring language
    25 : History University of Wisconsin Used simulated case scenarios and estimated the efficiency of the student in arriving at a diagnosis (cost-effectiveness)
    26 : History Initial installations site limited Subsequent modem dial-up Proliferation of medical CAI, CME development entities Development of the internet Initial material bandwidth limited Increasing use of streaming video
    27 : Modes of CAI Drill and practice Material presented with immediate testing Grading and progress or loop back Poor students benefit Didactic Lecture with the advantage of time and place independence No questions Howard Hughes Institute Penn site
    28 : Modes Discrimination learning Many clinical situations require practitioner to differentiate between different clinical manifestations 3 days cough and fever Red rash Computer can help the student learn to recognize subtle differences
    29 : Modes Exploration vs. structures interaction Hyperlink analogy Requires feedback/guidance
    30 : Modes Constrained vs. unconstrained response Student may have a pre-selected set of possible response (learn to answer questions) Student may be able to probe system using natural language
    31 : Modes Constructive Put the body together from pieces of anatomy
    32 : Simulation Static vs. dynamic
    33 : Static simulation
    34 : Dynamic simulation
    35 : Feedback and guidance Feedback Correct vs. incorrect Summaries References Guidance Tailored feedback Hints Interactive help
    36 : Intelligent tutoring Sophisticated systems can Intervene if a student goes down an unproductive path Gets stuck Appears to misunderstand a detail Mixed initiative systems Coaching vs. tutoring
    37 : Graphics and Video Storage of images, video etc as part of a multimedia stream General appearance Skin lesions Xrays Sounds (cardiology, breath sounds)
    38 : Authoring systems Generic authoring systems McGraw Hill, Boeing Simple (constraints) vs. comprehensive (difficult to master)
    39 : Examples USMLE Lister Hill Stanford anatomy Digital anatomy Penn curriculum Medical matrix
    40 : Continuing medical education Echo PAC CME
    41 : Simulators ACLS Visible human Eye simulator Other simulators
    42 : Future Forces for change Impediments Cost Immaturity of authoring tools Bandwidth Barriers to sharing Institutional jealousy Copyright
    43 : Future Lack of standard approach Authoring software Platform Explicit integration of CAI into curriculum Access to PC’s and LAN
