Dr. Tremendous: interactive economics teaching tools

Dr.Tremendous T-rex mascot Dr.Tremendous · Solutions, made visible.

Interactive tutors, sound toys, calculators, and simulations
built for the way undergraduates actually learn.

THE COLLECTION

Care, built into the structure.

In a small class, students are naturally visible. In large and online courses, visibility has to be designed. These tools are one way I do that.

Study Tools
Two tools that work together: adaptive practice serves questions at each student’s level, and a Socratic tutor walks them through whatever they miss, without handing over the answer.

What students doDraft five commodities, guess NC’s national rank, then dig into the board and map.
Game · Live
The NC State
Agriculture Game
Draft five North Carolina commodities and predict where the state ranks nationally, then explore a searchable big board of ~30 commodities, an interactive county map, and a myth-or-fact quiz. Every rank is pulled straight from USDA data.

What students doCrank the correlation, draw samples, watch β̂ swing.
Visualizer · Live
The Sorting
Machine
Watch variance in Y get sorted into bins for each predictor. Crank the correlation and draw new samples to see coefficients swing, and flip sign, while R² holds steady. Multicollinearity, made visible.

Supply & Demand
Practice
Five levels of curve-dragging, from classifying shifts up to simultaneous shocks and real news scenarios. Drag the curves, watch equilibrium move, check your reasoning.

What students doWhisper a rumor, decide the weather, watch belief move prices before facts do.
Simulation · Live
The Whisper
Market
Five towns, one rumor. Plant a whisper of drought in a trader's ear, then watch supply shift on belief alone, before you've even decided whether the drought is real. Three rounds: the Whisper, the Washout, and Your Valley, wide open.
Expectations move markets

What students doDraft an item, then rank what you passed up, and meet your real opportunity cost.
Game · Live
Drive-Thru Draft:
Opportunity Cost
The five-spin fast-food draft, turned into an economics lesson. After each pick you rank what you turned down, and the game names your true opportunity cost: the single next-best thing given up, never the whole pile. A round-two "taste test" even checks whether your stated ranking matched what you actually chose.
Opportunity cost, made real

What students doOpen several tabs, fish one shared pond, watch it collapse, then vote a quota.
Simulation · Live
Every Tab
for Itself
Open the game in two or more browser tabs: each tab is a fishing boat on one shared pond. Fish freely and the stock crashes for everyone; then a council votes a catch limit and you find out whether a rule on paper survives the temptation to break it. The tragedy of the commons, played across your own browser. Best on a laptop with a few tabs open.

What students doSort each cost, compute both profits, reveal the waterfall.
Interactive · Live
The Economic
Profit Lab
Sort each cost as paid-out or given-up, compute accounting vs. economic profit, then reveal an animated waterfall and a balance scale that weighs the venture against the owner's next-best life. Opportunity cost, made visible.

The Quick Fix
Simulator
A bridge is out and costs are climbing. Interview four AI stakeholders, build an evidence board, watch the market model shift, then write a policy memo an AI instructor assesses on economic reasoning.

Stakeholder Heatmap
Pick a claim about an agricultural minimum wage. The board flips from quiet to illuminated, showing who benefits, who bears pressure, who has mixed incentives, and whose concerns are missing.

Side Quests.

The main quest is the teaching tools. These are what happens when the same brain points itself at something purely for fun, and the mechanism still ends up on the page.

The whole project: turning ideas about teaching into things students can actually use.
