Navigate realistic research scenarios where your methodology decisions have consequences. This case-based approach helps you build research planning skills and learn from "failed" experiments without real-world costs.
Learning Objectives
Evaluate experimental methodology options and their implications
Make informed decisions about instrumentation, controls, and variables
Anticipate how early choices affect data quality and conclusions
Learn from failed approaches without real-world time/cost penalties
How You Progress
Your research decisions are evaluated across five key dimensions:
Validity: Controls for confounds, appropriate sample size
Reliability: Measurement precision, replicability
Efficiency: Resource use (time, budget, equipment)
Impact: Ability to answer research question definitively
What You'll Achieve
You'll develop research planning skills with foresight about experimental consequences, pattern recognition for common pitfalls, ability to justify methodology choices, and resilience through learning from failed experimental paths.
Interactive Prototype
How to Use: You're the principal investigator planning a materials research study. Read the research scenario below, then make decisions at each critical choice point. Select the option that best balances validity, reliability, efficiency, safety, and impact. After each decision, you'll see the consequences of your choice. Complete all 5 decisions to receive your research quality rubric and expert feedback.
Research Scenario: Material Fatigue Study
You're investigating fatigue life of a new aluminum alloy for aerospace applications. Your goal is to determine how many load cycles the material can withstand before failure under different stress levels.
Budget: $50,000 | Timeline: 6 months | Deliverable: S-N curve (stress vs. cycles to failure)

Decision 1: Sample Size & Test Points
How many specimens and stress levels should you test to build a reliable S-N curve?
Decision 2: Testing Equipment Selection
Which fatigue testing system should you use?
Decision 3: Environmental Controls
What environmental conditions will you maintain during testing?
Decision 4: Data Collection Strategy
How will you monitor crack initiation and propagation?
Decision 5: Statistical Analysis Plan
How will you analyze and present your fatigue data?
