Using Computer-Simulated Case-Based Scenarios to Improve Learning Department of Health Professions College of Health & Public Affairs University of Central Florida David M. Segal PhD Assistant Professor
Case-based Learning The effectiveness of case-based instruction in education is supported by a significant body of research Teaching health science students how to work in teams in the classroom with members of varying experience and skill levels offers valuable real-life simulated learning which will better prepare them for the healthcare workplace Students with strong critical thinking skills make better clinical decisions Focus shifts towards higher order processing skills rather than merely content How can we assess context-specific critical learning? How can technology mediate this?
Pedagogy Poll Question How many use the following teaching methods to deliver your content? a.case-based learning b.problem-based learning c.team-based learning d.collaborative learning e.web-based instruction (WebCT, Blackboard) f.other
CBL Poll Question What system do you use to implement case-based teaching? a.paper-based b.word c.powerpoint d.wimba e.animations f.immersive (second-life, active worlds) g.mannequins h.standardized patients i.role-plays (students)
What is critical thinking? Students demonstrate the ability to think by being able to: Analyze complex issues and make informed decisions; Synthesize information in order to arrive at reasoned conclusions; Evaluate the logic, validity, and relevance of data; Solve challenging problems; Use knowledge and understanding to generate and explore new questions; Distinguish between observation and inference; Identify the axioms/assumptions in any argument and judge their validity; Identify the nature of the reasoning being used. Know when inductive or deductive reasoning is required; Use circular reasoning to reflect on decisions.
Program Decision-Making Learning Outcomes Demonstrate proficiency with scientific content Demonstrate critical thinking skills in critically evaluating context-specific data for relevance, consistency, and fidelity Demonstrate proficient decision-making skills to determine the best diagnosis and treatment for simulated patient Demonstrate proficiency with integration of scientific content to identify the etiology, pathogenesis, clinical manifestations, diagnosis, and treatment for patient Demonstrate information fluency by retrieving, interpreting, and critically evaluating published literature for most relevant evidence-based scientific studies Articulate clinical expertise by communicating the risks and benefits for different courses of action to treat patients

WebCT Limitations How can you assess critical thinking and decision making skills in WebCT environment? How can you implement critical thinking exercises in large online classes? How can you grade asynchronous activities with large online classes? How can you conduct group collaborative work with text-based synchronous chatrooms?
Patient Case Library Over 300 cases are available Initial history, additional history, differential diagnosis, laboratory & diagnostics, diagnosis, treatment, subsequent history Primary System disorders Immunity (25) Oxygen transport (15) Cardiopulmonary (35) Fluid/electrolyte (15) Acid-base (15) Renal/bladder (35) Urogenital (30) Gastrointestinal (35) Endocrinology (25) Musculoskeletal (35) Integumentary (20) Neurological (35)
Improved Clinical Decision-Making Outcomes using Case study Learning SIMULATED CASES RESULTS Pre- and post-examinations of clinical case scenarios Group I:11 +/- 2% (p<0.001) Group II:19 +/- 3% (p<0.001) Group III:31 +/- 4% (p<0.001) *positive improvements in scores relative to control group IV Group I:Online static text case scenarios (n=200) Group II:Online interactive case scenarios (n=200) Group III:Online interactive virtual character case scenarios (n=200) Group IV:No case scenario training (control; n=200)
Post-usage survey results participant opinions about validity, performance characteristics, and utility for training 1. Are the scenarios enjoyable? 2. Do the scenarios address important clinical competencies? 3. Do participants view the simulation as a learning tool? 4. Is improved technical fidelity required for authenticity? 5. Was the session realistic? Improved Clinical Decision-Making Outcomes using Case study Learning strongly agree strongly disagree agree or disagree * statistically significant difference (p<0.001) * * * * * * * * * * Group I:Online static text case scenarios Group II:Online interactive case scenarios Group III:Online interactive virtual character case scenarios Group IV:No case scenario training (control)
Collaborative Technology Poll Question What technology have you used to promote collaborative learning in your students? a.classroom paper-based b.videoconferencing c.classroom response systems d.immersive environment e.other

Multi-disciplinary Collaborative Groups Individual case work Group I: Medical Pharmacology 1 (n=29)16 +/- 6% Group II: Medical Pharmacology 2 (n=24)18 +/- 8% Group III: Pathophysiology (n=25)26 +/- 8% Collaborative case work Group IV: Pathophysiology/Med Pharm 1 (n=80)37 +/- 8% Group V: Pathophysiology/Med Pharm 2 (n=80)44 +/- 6%
RESULTS: Students prefer computer simulated case studies for convenient access, collaboration, and varied attributes Cases can be designed with multi-nodal decision points to enhance interactive experience Improvements in student critical thinking and decision-making skills are observed in cases which are relevant and realistic cases compared to challenging and engaging attributes Most significant improvements observed in cases with basic science and clinical aspects Computer-simulated case scenarios can be developed for any discipline using this system and these case-building concepts Contact: David Segal, PhD
