📚 THE RESEARCH

FOR PARENTS & TEACHERS: The core mechanics in Loot Lab are tied to published evidence, and the evidence is sorted honestly. TIER 1 lists causal evidence: randomized trials and IES/WWC practice-guide recommendations. The guide panels grade each recommendation's evidence MINIMAL, MODERATE, or STRONG (minimal-evidence recommendations rest partly on panel expert opinion), and every card below prints the level it leans on. One more honest note: these studies test the teaching practices the game borrows, not this game itself.

TIER 1: CAUSAL EVIDENCE (randomized trials and WWC evidence syntheses)
🎮 Marble-bag sims: probability you can WATCH (live draws, tallies, and bags that shrink when there is no replacement)
Two WWC practice guides converge here: use visual representations in problem solving (Woodward et al., Rec 3, rated STRONG) and use concrete and semi-concrete representations (Fuchs et al., Rec 3, rated STRONG). The sims make the sample space visible: players see the 3 blue out of 13 marbles before anyone asks them to compute P(blue).

Woodward et al. (2012), NCEE 2012-4055, Rec 3: visual representations (Strong). Fuchs et al. (2021), WWC 2021006, Rec 3: representations (Strong).

🎮 Lesson first, then challenges, with immediate feedback on every answer
Explicit, systematic instruction with immediate corrective feedback is a STRONG-rated WWC recommendation (Fuchs et al., Rec 1; all six recommendations in that guide are rated Strong). Every world teaches before it tests, and every miss gets an explanation of the correct route, not just a buzzer.

Fuchs et al. (2021), Rec 1: systematic instruction (Strong).

🎮 The hint button before answering, the explanation after every miss
Prompting students to monitor and reflect during problem solving is a STRONG-rated WWC recommendation (Woodward et al., Rec 2). The hints coach the plan, not the answer ("2/5 for the first key, then 1 working key of 4 left"), so players check their reasoning mid-problem.

Woodward et al. (2012), Rec 2: monitoring and reflecting (Strong).

🎮 Compound events built step by step, and WITH vs WITHOUT replacement computed side by side on the same bag
The WWC algebra guide recommends teaching and comparing alternative solution approaches on the same problem (Star et al., Rec 3, rated MODERATE). The steppers build P(A then B) one draw at a time, and the with-replacement and without-replacement routes are set next to each other on the same bag so players see exactly where the denominators change.

Star et al. (2015), NCEE 2015-4010, Rec 3: alternative strategies (Moderate).

DESIGN CHOICES WITH MIXED EVIDENCE (labeled honestly)
🎮 The comic voice: tycoon gags that restate the math
The design basis is Ziv's two semester-long randomized experiments with college students: classes taught with content-related humor scored higher on the same final exams. Honest caveat: experimental evidence on classroom humor in K-8 is thin, and one recent college experiment found integrated humor REDUCED learning. That is why the humor here follows content-linked guardrails: jokes restate the math being taught, and quips live between rounds, never in place of instruction or feedback.

Ziv (1988): two randomized semester experiments, college students, content-related humor. Bolkan, Griffin & Goodboy (2018): college experiments where integrated humor lowered test performance.
