Description

A simulation is an interactive model of a real or hypothetical system — physical, biological, economic, social, or procedural — in which learners take actions, observe the consequences, and adjust their approach. Unlike a Demonstration, which presents expert performance for observation, a simulation makes the learner the actor, embedding practice inside a simplified environment where errors are safe and consequences are visible.

Design Implications

Simulations support learning by making system dynamics explorable: learners build causal mental models by manipulating variables and observing outcomes, which is difficult to convey through exposition alone [~M]. Their effectiveness depends on structure — unguided exploration of a complex simulation can overwhelm novices, so effective designs pair the environment with goals, prompts, or Scaffolding [~S]. Simulations are most powerful when followed by debriefing, in which learners articulate what happened and why; without debriefing, experience alone often fails to produce transferable understanding [~M].

Context

Requirements

• A model whose behavior is faithful enough to the target system that inferences from it transfer
• Clear goals or challenge scenarios that direct exploration toward the learning objective
• Feedback that makes the link between actions and outcomes visible (Feedback)
• A structured debrief or reflection step that converts experience into generalizable principles

Constraints

• Unguided discovery within a simulation is ineffective for novices; minimal-guidance exploration produces poorer learning than structured instruction [~S] — learners may draw wrong conclusions from the model or flounder without building usable schemas
• Simulations of complex systems can impose heavy extraneous load; without Cognitive Load Management, learners attend to interface mechanics rather than underlying principles
• A simplified model can teach misconceptions if its divergences from reality are not made explicit
• Fidelity costs: high-fidelity simulations are expensive to build and maintain, and added fidelity does not reliably improve learning outcomes [~W]

Target Learners

• Novices who need to build an initial causal model of a system before formal instruction [~M]
• Intermediate learners consolidating and testing understanding through experimentation
• Learners for whom real-world practice is dangerous, expensive, slow, or ethically impossible (e.g., flight, surgery, emergency response)
• Less beneficial for learners with strong prior knowledge, who may extract little from guided exploration Expertise reverses the benefit of instructional guidance. [~M]

Target Learning Goals

• Conceptual understanding of dynamic systems and causal relationships
• Procedural fluency and decision-making under realistic constraints
• Transfer: applying principles across varied scenarios by experiencing multiple cases
• Diagnosis and troubleshooting: interpreting system states and responding

Affordances

• Active Learning — simulation enacts this principle by requiring learners to generate actions and predictions rather than receive explanations; the environment responds to what the learner does, not what the learner is told
• Scaffolding — simulations can stage complexity, starting with few variables and adding them as competence grows; Fading applies naturally by progressively removing hints, prompts, and constraints
• Cognitive Load Management — a well-designed simulation strips away irrelevant real-world complexity, letting learners attend to the variables that matter
• Feedback — the simulation's response to learner actions is immediate, task-level feedback; effectiveness rises when debriefing elevates it to the process level Feedback is most effective at task and process levels. [+S]

Design Decisions

How much guidance should learners get inside the simulation?

• Default: give novices structure — goals, prompts, feedback, worked examples — rather than leaving them to discover the model's rules unaided; explicit instruction beat unassisted discovery (d = 0.38, 580 comparisons), while discovery enhanced with feedback, worked examples or scaffolding beat other instruction (d = 0.30) — Minimal guidance is less effective for novices than explicit instruction [+S], Guided discovery outperforms pure discovery [+S]
• Default: in inquiry settings, teacher-led guidance outperformed student-led conditions by about .40 in effect size (37 studies, overall g = .50) — Teacher-guided inquiry outperforms student-led [+S]
• Changes when: learners already hold the relevant schemas → fade the guidance; formats that help novices lost their advantage, and in several paradigms reversed, for more experienced learners — Expertise reversal: guidance hurts experts [~S]
• Tested with: meta-analyses of discovery and inquiry learning (largely school science), 112 third- and fourth-graders learning experimental design, electrical trainees reading circuit diagrams; none of these claims tests guidance levels inside a simulation specifically.
• Not settled: how fast to fade guidance within a simulation, and whether the discovery findings carry over unchanged to interactive models; no wiki claim tests it.

What should the simulation be built around?

• Default: repeated, goal-directed practice with mastery standards and immediate feedback; simulation-based medical education with deliberate practice beat traditional clinical education (d = 0.71, 14 studies, mostly procedural skills) — Simulation-based education with deliberate practice improves clinical outcomes [+M]
• Default: against no intervention, technology-enhanced simulation gave large pooled effects on knowledge and skills (g ≈ 1.09–1.20) and a moderate one on direct patient outcomes (g = 0.50, k = 32) — Simulation-based education improves outcomes [+M]
• Changes when: the comparison is equally long non-simulation practice → the no-intervention meta-analysis cannot say, and its subgroup analyses found no consistent interaction with feedback, repetition, mastery learning, distributed practice or curricular integration — Simulation-based education improves outcomes [~M]
• Tested with: physicians, nurses, dentists and other health-professions trainees (609 studies, 35,226 trainees; 14 studies for the deliberate-practice comparison).
• Not settled: which design features drive the effect, how durable gains are, dose–response for amount of practice, and cost against low-fidelity alternatives; both claim pages list these as open.

How realistic does the simulation need to be?

• Default: a virtual model can stand in for physical materials for conceptual learning; physical, virtual and combined manipulation of heat-and-temperature experiments were equally effective and all beat traditional instruction — Physical experience enhances science learning [~M]
• Changes when: the goal is reflecting on the situation → a simplified virtual simulation gave higher self-reported purposefulness of reflection than authentic video (d = 0.507) — Virtual simulation stimulated higher self-reported purposefulness than authentic video [+M]
• Changes when: the goal is analysing rich real situations → authentic video outscored the simplified simulation on the analysis and support dimensions of observation assignments — Authentic video outperformed virtual simulation on analysis and support dimensions [-M]
• Tested with: 234 undergraduates in physics (physical vs virtual); 34 preschool teacher candidates in 8 groups in one design-based study (simulation vs video), which is one small study.
• Not settled: fidelity levels in procedural or clinical simulation; no wiki claim compares high- and low-fidelity versions of the same simulation, so the Constraints line above on fidelity cost rests on no recorded study.

What should learners get before the simulation?

• Default: a short primer naming the parts and functions of the system; a pretraining video before an immersive-VR procedural lesson gave better knowledge scores and fewer errors on a real-world transfer task, with lower reported load — Pretraining improves transfer [+M]
• Tested with: 93 participants learning a micropipette procedure in VR; one randomised experiment, read as an abstract, no effect size.
• Not settled: whether pretraining is redundant for learners who already know the terms (the claim page expects so but records no test), and whether gains last to delayed tests.

What feedback should the simulation itself give?

• Default: say why a response is wrong, not only that it is; high-information feedback (d = 0.99) far outperformed reinforcement or punishment (d = 0.24), and over a third of feedback interventions lowered performance — Feedback improves learning [+S]
• Default: students in a computer-based clinical simulation found right/wrong marking without reasoning not beneficial — Students find computer-based simulation feedback insufficient [+M]
• Default: let learners retry cases without grade penalty; students rated an unlimited-attempts learning mode highly beneficial — Graduate SLP students perceive the simulation's learning mode as highly beneficial [+M]
• Tested with: 435 education studies and 607 effect sizes across settings (feedback); 10 speech-language pathology graduate students in one focus-group pilot (the two simulation claims, which report perceptions, not learning).
• Not settled: immediate versus end-of-scenario feedback inside a simulation; no wiki claim tests it.

What should follow the simulation?

• Default: a structured reflection with specific prompts rather than a generic invitation; metacognitive-reflection prompts were the strongest moderator in 48 writing-to-learn studies (b = 0.48), and specific prompts beat generic ones for 208 engineering students — Reflective practice improves outcomes when structured [+S]
• Default: students in a simulated clinical course named the weekly debriefing among its most beneficial parts — Students perceive debriefing as among the most beneficial components of a simulated clinical course [+M]
• Tested with: school writing-to-learn studies and a first-year engineering course (structured reflection); 10 SLP graduate students (debriefing, perception only).
• Not settled: no wiki claim compares a simulation with and without a debrief; see Debrief for the debrief's own decisions.
