Every design heuristic in this handbook is traceable to a source. The list below grounds Parts 1–2 (foundations + design toolkits) and the case material in Part 3. Where the handbook says “research-informed,” this page is what's behind it.
Where each claim lands.
| Claim in this handbook | Primary source(s) |
|---|---|
| Teacher facilitation and curriculum context can moderate whether GBL is usable and connected to classroom outcomes. | Jong, Dong, & Luk (2017); Nousiainen et al. (2018); Sharma et al. (2024) |
| Frameworks commonly recommend mapping learning objectives to game mechanics; the mapping is a design aid, not a validated predictor by itself. | Plass, Homer, & Kinzer (2015); Annetta (2010); Arnab et al. (2015) |
| Gamification effects vary by design and context; pooled effects should not be treated as a guarantee for a particular implementation. | Sailer & Homner (2020) |
| Meta-analyses report positive pooled effects for critical-thinking or computational-thinking outcomes in particular study sets; moderators, heterogeneity, and transfer limits matter. | Mao, Cui, Chiu, & Lei (2022); Lu, Chiu, Cui, Mao, & Lei (2023) |
| Playtest with target learners — not proxies — is a recurring stakeholder-design recommendation. | Bunt, Greeff, & Taylor (2024); Silva (2020) |
| Cognitive load theory's intrinsic / extraneous / germane distinction guides screen-element pruning. | Sweller, van Merriënboer, & Paas (2019) |
| Backward-design discipline — outcomes → evidence → mechanics — for the D2 crosswalk. | Wiggins & McTighe (2005) |
| Micro-credential workload + quality-assurance bands. | Council of the EU (2022); MicroHE (2020); MICROBOL (2022); NZQA (2026); ENQA (2023); OECD (2021, 2023); Varadarajan, Koh, & Daniel (2023); Ahsan et al. (2023) |
| Three.js implementation primitives (D5 bridge module). | three.js manual + docs (2026) |
