A Tale of Two Stories • A Game of India – H. A. Nielsen (Michigan Quarterly Review, 1978) – Experience first … then understanding – Humility … we know less than we are inclined to believe • A Confession – Lev Tolstoy, 1884 – Learning as disturbance – Quine & Ullian’s Web of Belief – The interconnectedness of experience Learning Systems Institute, Florida State University, Suite 4600 -C University Center, Tallahassee, FL 32306 -2540 (PHONE): (850) 644 -2570 (FAX): (850) 644 -4952 URL: WWW. LSI. FSU. EDU
Why • Natural inclination – It is what people do • Memory – efficiency of episodic memory (Anderson, 1983; Schacter, 1996) – efficient encoding, decoding and recall • Complexity – Confronting complexity indirectly – tacit knowledge Learning Systems Institute, Florida State University, Suite 4600 -C University Center, Tallahassee, FL 32306 -2540 (PHONE): (850) 644 -2570 (FAX): (850) 644 -4952 URL: WWW.

When • With younger learners – widespread acceptance • With millennials … growing expectations • With what types of instructional goals and tasks? • With non-recurrent, ill-structured, complex, dynamic problem solving tasks!

Automatic Generation of Stories People tell stories. They tell stories to fit a situation or need. The use of stories in that sense is dynamic. Can an instructional computing system tell a story based on an underlying mathematical model and problem scenario or need? This possibility exists – an important research agenda worth pursuing. Learning Systems Institute, Florida State University, Suite 4600 -C University Center, Tallahassee, FL 32306 -2540 (PHONE): (850) 644 -2570 (FAX): (850) 644 -4952 URL: WWW. LSI. FSU. EDU

Generating a Problem • Create and validate a system dynamics simulation model for a complex, dynamic system – a non-trivial task but many such simulation models already exist • Ensure that each variable, stock and constant are well documented • Given the current state of the simulation model and the learner’s experience, generate a problem situation from the model itself Learning Systems Institute, Florida State University, Suite 4600 -C University Center, Tallahassee, FL 32306 -2540 (PHONE): (850) 644 -2570 (FAX): (850) 644 -4952 URL: WWW.

This depicts a system dynamics model – the highlighted flow rate is opened. There is a documentation tab in Power. Sim that allows each component to be described. This can be used to generate a task for someone interacting with the simulation model.

Assessing Learning with Stories How well do stories support learning in and about complex, ill-structured domains? How to determine? - standard problems with standard solutions are not available A developmental pathway - inexperienced problem solving and decision making towards expert-like problem solving and decision making Learning Systems Institute, Florida State University, Suite 4600 -C University Center, Tallahassee, FL 32306 -2540 (PHONE): (850) 644 -2570 (FAX): (850) 644 -4952 URL: WWW.

DEEP – An Assessment Tool http: //deep. lsi. fsu. edu/DMVS/jsp/index. htm • Problem – determine progress of learning in complex domains • Approach – identify and annotate key influence factors • Strategy – compare responses to those of known experts and track development • Tactic – minimize extraneous cognitive load on respondents Learning Systems Institute, Florida State University, Suite 4600 -C University Center, Tallahassee, FL 32306 -2540 (PHONE): (850) 644 -2570 (FAX): (850) 644 -4952 URL: WWW.

Capturing Problem Conceptualizations Present a problem situation or scenario, ask respondents to: 1. indicate factors (name and briefly describe) they believe critical to resolving the situation 2. indicate how these factors are interrelated (draw links and describe relations) 3. identify the assumptions involved thus far 4. describe additional information that would be required to resolve the situation or solve the problem Learning Systems Institute, Florida State University, Suite 4600 -C University Center, Tallahassee, FL 32306 -2540 (PHONE): (850) 644 -2570 (FAX): (850) 644 -4952 URL: WWW.

Additional Issues & Measures • Separating structural and semantic analysis • Structural analysis – Central nodes – Terminal nodes (all links in same direction) – Feedback and systemic measures • Similarity metrics – Graph theory – diameter, density, path analysis – Tversky similarity metric Learning Systems Institute, Florida State University, Suite 4600 -C University Center, Tallahassee, FL 32306 -2540 (PHONE): (850) 644 -2570 (FAX): (850) 644 -4952 URL: WWW.

First Pass at a Systemic Metric • Hypothesis: experts will tend to think more systemically than non-experts • Indicators of systemic thinking: – Internal feedback (links back to other parts of the system; two-way links) – One possible measure – ratio of unreachable pairs to all possible ordered pairs of nodes in the problem conceptualization Learning Systems Institute, Florida State University, Suite 4600 -C University Center, Tallahassee, FL 32306 -2540 (PHONE): (850) 644 -2570 (FAX): (850) 644 -4952 URL: WWW.
