# Video Games and Homeschool Learning source ledger

Last reviewed: 13 August 2026

## Source classes

| Class | Use in report | Interpretation rule |
|---|---|---|
| Official health guidance | Child development and gaming-disorder boundaries | Guidance is not a causal study or universal family prescription |
| Child-rights and consumer protection | Safety, privacy, monetization, and platform design | Regulatory allegations and settlements are scoped to named conduct and jurisdiction |
| Systematic review or meta-analysis | Direction and consistency across studies | Average effects retain heterogeneity, population, outcome, and publication-bias limits |
| Randomized or controlled study | Bounded intervention claim | Never generalize from one game, age group, dose, or outcome |
| Observational study | Association and hypothesis | Never describe association as causal; corrections travel with the citation |
| Mechanics-based interpretation | Family observation and task design | Supports a question or artifact, not a scientific outcome claim |

## Primary evidence ledger

| Source | Class | Population or scope | Claim supported | Boundary retained |
|---|---|---|---|---|
| AAP Digital Ecosystems policy and technical report (2026) | Official professional guidance | Children and adolescents | Move beyond a single screen-time metric; consider child, content, context, design, and displacement | U.S. pediatric guidance, not a homeschool curriculum or trial |
| Minecraft Education cluster RCT (2024) | Randomized classroom study | 32 classes, 885 primary pupils | No overall spatial-thinking improvement; fifth-grade subgroup finding; control creativity result | One structured intervention, age group, curriculum, and outcome set |
| Sala, Tatlidil, Gobet (2018) | Meta-analysis | Video-game training studies | Far transfer to general cognitive ability is not reliable | Does not imply no task learning or near transfer |
| Game-factors meta-analysis (2023) | Meta-analysis | 63 studies, 118 investigations, N=2,079 | Modest overall cognitive-training effect and importance of game factors | Heterogeneous interventions and outcomes; not ordinary play |
| Super Mario 64 study (2014) | Adult experimental neuroimaging | Adults trained for two months | Structural brain plasticity under study conditions | Not a child academic, intelligence, or far-transfer result |
| ABCD gaming article and correction notice | Cross-sectional observational study | U.S. children aged 9-10 | Associations with cognitive task outcomes; correction hygiene | Retracted and replaced; observational; genres insufficiently distinguished |
| Dyslexia-risk action-game study (2024) | Targeted intervention | Pre-readers at risk for developmental dyslexia | Promising phonemic-awareness result | Not ordinary commercial gaming or substitute for care |
| Exergaming systematic reviews (2023-2024) | Systematic reviews/meta-analyses | Children in controlled interventions | Some executive and motor outcomes improved | Heterogeneity; some non-significant outcomes; not broad physical-activity replacement |
| WHO ICD-11 gaming-disorder FAQ | Official health classification | Global clinical classification | Impaired control, priority, and continuation despite harm | Enthusiasm or long sessions alone are not diagnosis |
| Problematic gaming comorbidity review (2024) | Systematic review | Adolescents | Associations with ADHD, anxiety, depression, and behavioral/emotional problems | Direction and causation remain unresolved |
| UNICEF online-gaming work | Child-rights guidance | Global platforms and children | Safety, privacy, commercial design, and children’s rights belong in evaluation | Guidance and sector analysis, not learning-outcome research |
| FTC Epic Games and Genshin Impact actions | Government enforcement | Named U.S. cases | Documented concerns involving dark patterns, unauthorized charges, privacy, and loot boxes | Case-specific allegations, orders, and settlements; not all games |
| STEM game-learning meta-analysis (2023) | Meta-analysis | Learners across age bands | Digital educational games can support STEM outcomes in some designs | Educational interventions, not brand-level claims |
| Gamification meta-analysis (2023) | Meta-analysis | Educational settings | Positive average learning effects with moderators | Gamification is not equivalent to commercial gaming |

## Claim-control rules

1. Describe the mechanic before inferring a learning process.
2. Separate task improvement, near transfer, intermediate transfer, and far transfer.
3. Keep age, sample, intervention, comparator, outcome, and study design attached to every empirical claim.
4. Attach retraction or correction status wherever the ABCD result appears.
5. Treat named commercial games as examples unless directly studied.
6. Do not translate neural measures into school achievement without direct evidence.
7. Do not translate a targeted clinical intervention into treatment advice.
8. Distinguish recreational value from educational evidence; recreation does not require academic relabelling.
9. Include platform safety and monetization in any whole-child suitability claim.
10. Record demonstrated learner work without claiming that the game caused it.
