    [28th August 2025] The Hindu Op-ed: Play Based Learning for India’s Future

    PYQ Linkage

    [UPSC 2016] Examine the main provisions of the National Child Policy and throw light on the status of its implementation.

    Linkage: The National Child Policy envisions ensuring survival, development, protection, and participation of every child. Initiatives like Poshan Bhi Padhai Bhi, Aadharshila, and Navchetna operationalise this by transforming Anganwadis into learning hubs and focusing on early stimulation. This reflects concrete implementation of policy goals through structured ECCE and parental involvement.

    Mentor’s Comment

    India’s vision of Viksit Bharat depends on nurturing its youngest citizens. By placing Early Childhood Care and Education (ECCE) at the core of policy, Anganwadi centres are being reimagined as the first classrooms, not just nutrition hubs. This editorial highlights the significance of play-based learning, the reforms underway, and their impact on social, economic, and human capital development.

    Introduction

    Nation-building begins where learning begins, in Anganwadis and playschools where children first explore and imagine. Since 85% of brain development occurs before six, India has prioritised structured, play-based learning. Initiatives like the National Education Policy (NEP) 2020, Poshan Bhi Padhai Bhi, Aadharshila curriculum, and Navchetna framework mark a decisive shift: education is no longer seen as starting at school, but from birth itself.

    Why in the News?

    Play-based learning has become a national policy priority under the present government. Anganwadi workers are being trained in ECCE, and centres are evolving into early learning hubs. This marks a historic policy turn, shifting focus from higher education to the earliest years of life, where investments yield the highest returns. Evidence shows ECCE can raise IQ levels by up to 19 points and deliver 13–18% returns (Heckman), making it one of the most impactful reforms in recent times.

    Reimagining Anganwadis as Learning Hubs

    1. Anganwadis as First Schools: Transition from nutrition centres to vibrant learning hubs.
    2. Poshan Bhi Padhai Bhi: A flagship initiative introducing structured ECCE and play-based learning.
    3. Training of Workers: First-ever systematic training of Anganwadi workers in ECCE methods.
    4. Budgetary Support: Enhanced allocations for teaching-learning materials.
    5. Community Trust: Parents now view Anganwadis as the foundation of their child’s education.

    Scientific Evidence Supporting ECCE

    1. Brain Development: NEP 2020 highlights 85% of brain growth occurs before six years.
    2. CMC Vellore Study: Children exposed to 18–24 months of ECCE gained up to 19 IQ points by age five, and 5–9 points by age nine.
    3. Global Research: Nobel Laureate James Heckman shows 13–18% returns on early childhood investments.

    Ensuring Holistic Development in Early Childhood

    1. Aadharshila Curriculum: National ECCE framework for children aged 3–6 years.
    2. 5+1 Weekly Plan: Balance of free play, structured learning, creativity, motor skills, social interaction, and values.
    3. Focus Beyond Cognitive Skills: Emotional, social, and physical development equally emphasised.
    4. Outdoor Play & Emotional Bonds: Ensuring resilience, socialisation, and value-building.

    Birth-to-Three: The Neglected but Crucial Stage

    1. Navchetna Framework: National framework for Early Childhood Stimulation.
    2. Parental Involvement: Empowering caregivers with play-based activities at home.
    3. Equity Focus: State as equaliser for low-income families lacking resources.

    Play-Based Learning as a Tool for Nation-Building

    1. Human Capital Formation: Better prepared children ensure stronger productivity.
    2. Social Inclusion: ECCE bridges gaps between privileged and underprivileged children.
    3. Nation’s Future: Early learning reduces dropout rates and improves long-term educational outcomes.

    Conclusion

    If India is to realise its vision of Viksit Bharat @2047, it must begin where life begins. By making play a policy, and not merely leisure, India is reshaping its future workforce and citizens. Anganwadis as learning hubs, structured ECCE, and parental engagement are steps that will yield dividends not just in GDP growth, but in nurturing empathetic, curious, and resilient human beings. Play is no longer child’s play, it is nation-building.

    Value Addition

    Anganwadis

    • Scale and Reach: Over 13.9 lakh Anganwadi Centres (AWCs) functioning under the Integrated Child Development Services (ICDS), covering nearly every village/urban ward.
    • Holistic Role: Provide nutrition, health check-ups, immunisation, pre-school non-formal education, and referral services — making them the convergence point for child and maternal welfare.
    • Policy Integration: Central to schemes like Poshan Abhiyaan, Poshan Bhi Padhai Bhi, and the Saksham Anganwadi & Poshan 2.0.
    • Early Childhood Development: With Aadharshila curriculum and Navchetna framework, AWCs are being repositioned as first schools ensuring ECCE and holistic growth.
    • Empowerment of Women: Run largely by women workers (anganwadi sevikas), providing local employment, social recognition, and female leadership at the grassroots.
    • Challenges: Issues of infrastructure gaps, irregular honorarium, workload burden, training deficits, and low community awareness remain barriers.
    • Global Alignment: Echoes UNICEF and UNESCO emphasis on early childhood care as foundational to human capital and demographic dividend.

    With Sci-Hub gone, will the ‘One Nation, One Subscription’ scheme step up?

    Introduction

    The blocking of Sci-Hub in India marks a turning point in the battle between corporate publishers and the principle of open knowledge. At the heart of the issue lies the paradox of publicly funded research locked behind exorbitant paywalls. The government’s One Nation One Subscription (ONOS) scheme, with an allocation of ₹6,000 crore, aims to democratize access to 13,000 journals for research institutions. Yet, concerns remain about its cost-effectiveness, inclusivity, and long-term sustainability.

    Why is this issue in the news?

    • The Delhi High Court’s verdict against Sci-Hub is a landmark moment because:
    • For the first time in India, the judiciary has formally sided with publishers in the long-drawn copyright battle.
    • It stands in sharp contrast with the reality that research is funded by public money but monetized by private publishers with 30%+ profit margins.
    • The problem is enormous: lakhs of rupees per journal subscription make access unaffordable for many institutions, forcing dependence on Sci-Hub earlier.
    • The government’s ONOS initiative is the first large-scale attempt to address structural inequities in knowledge access, but doubts persist about its ability to replace shadow libraries.

    The Distinctive Nature of Scientific Publishing

    1. No royalties for authors: Researchers and peer reviewers are unpaid, unlike musicians or filmmakers.
    2. Publicly funded research: Much of Indian science is taxpayer-funded, yet access is privatized.
    3. Exorbitant subscriptions: Institutions pay lakhs for a single journal. Publishers justify costs via “quality control” but enjoy 30%+ profit margins, raising concerns of rent-seeking.

    The Global Controversy Around Sci-Hub

    1. Copyright infringement: Courts in the U.S., Europe, and now India have ruled against Sci-Hub.
    2. Essential access tool: For countless researchers, Sci-Hub was the only means to access knowledge, especially outside elite universities.
    3. Contempt charges: Alexandra Elbakyan allegedly violated court orders by running Sci-Net, a mirror service.
    4. Declining relevance: Technical unreliability and growing open-access alternatives are reducing its utility.

    The Vision of One Nation, One Subscription

    1. Government-led subscription: Outlay of ₹6,000 crore (2023–2026) for bulk access to 13,000 journals.
    2. Phase I focus: All public institutions; Phase II may include private ones.
    3. Equal access: Seeks to eliminate inequities between elite and smaller research centres.
    4. Limitations: Independent researchers and those at private centres remain excluded until Phase II.

    ONOS in the Context of Global Open-Access Movements

    1. Global open-access movement: Over half of papers are already open access through preprints and repositories.
    2. U.S. policy (2026): All federally funded research must be open.
    3. EU Horizon Europe: Similar open-access mandate.
    4. India’s challenge: At a time when the world moves toward open access, ONOS risks becoming an expensive detour.

    Structural Flaws in Scholarly Publishing

    1. Dependence on foreign publishers: ONOS continues India’s reliance on Western journals.
    2. Copyright transfer: Indian researchers must still give away rights to their work.
    3. Pay-to-publish dilemma: Funds freed at institutions may shift to open-access journals, but may ignore institutional repositories.
    4. Need for rights retention: Policies like Harvard/MIT (mandatory deposit in repositories) could empower Indian researchers.

    Conclusion

    The Sci-Hub ban highlights the persistent inequities in access to scientific knowledge. While ONOS is a step forward, it risks being a band-aid solution unless paired with deeper reforms: indigenous publishing capacity, national repositories, and copyright retention policies. India must not merely manage the symptoms of an exploitative system but must cure the disease by reclaiming knowledge as a public good.

    Value Addition

    Knowledge as a Public Good

    • Publicly funded research must be accessible to all because it is financed by taxpayers.
    • Blocking access (through high subscription fees or court orders) creates an elitist knowledge economy.
    • UN and UNESCO treat knowledge access as a pillar of Sustainable Development Goals (SDG 4: Quality Education, SDG 9: Innovation).

    Economic Dimension

    • Global publishers enjoy 30%+ profit margins, while Indian institutions pay lakhs per journal subscription, draining public funds.
    • ONOS at ₹6,000 crore (2023–2026) represents bulk negotiation power by the state, saving scattered institutional expenditure.
    • Issue of dependency on foreign publishers persists, highlighting the need for indigenous publishing ecosystems.

    Global Comparisons

    • U.S. (2026 mandate): All federally funded research must be openly accessible.
    • EU’s Horizon Europe: Immediate open access to publications funded under the programme.
    • Plan S (Europe, 2018): Publicly funded research must be published in open-access journals.
    • India risks being out of sync if it over-invests in subscriptions while others move to free access models.

    Technology and Governance

    • ONOS = India’s experiment in e-governance for knowledge.
    • Needs to integrate institutional repositories, preprint servers, and rights retention policies (like Harvard/MIT) to empower researchers.
    • Can be linked with the Digital India mission, showing tech-driven democratization of services.

    Ethical Dimension

    • Applied Ethics of Technology: Corporate profits vs. collective social welfare.
    • Moral dilemma: Should intellectual property rights override public access to life-saving or path-breaking research?
    • Covid-19 demonstrated that open-access collaboration saved lives by accelerating vaccine and drug development.

    PYQ Relevance

    [UPSC 2024] ‘’What is the present world scenario of Intellectual Property Rights? Although India is second in the world to file patents, still only a few have been commercialized. Explain the reasons behind this less commercialization.”

    Linkage: The Sci-Hub ban and ONOS scheme reflect how IPR in scientific publishing creates barriers to access despite research being publicly funded. Globally, publishers extract high profits through restrictive copyright, mirroring the broader challenge of IPR becoming a tool of rent-seeking rather than innovation. India’s weak indigenous publishing ecosystem and overdependence on foreign journals parallel the problem of low commercialization of patents—both highlight the gap between innovation output and practical accessibility/utility.

  • Addiction, Not Play

    Introduction

    Online real-money gaming is no longer an innocent form of entertainment. With mechanics borrowed from gambling, variable rewards, high engagement loops, and rapid gratification, these games are engineered to create dependency. For India’s youth, this shift has manifested in addiction, financial losses, academic decline, and severe mental health crises. The government’s ban may seem like a safeguard, but the issue is deeper: India’s children deserve not just a firewall, but also psychological care, awareness, and structured support.

    Online Gaming Addiction as a Pressing Concern

    1. Gambling-like mechanisms: Real-money games mirror casino psychology, using reward loops to sustain engagement.
    2. Rising cases of harm: Children have drained family bank accounts, hidden debts, and even attempted suicide due to gaming stress.
    3. Mental health crisis: Anxiety, depression, and suicidal ideation among adolescents point to an urgent public health issue.

    The Fallout of Gaming Addiction on Families

    1. Toxic home environments: Addiction leads to secrecy, conflict, and breakdown of trust.
    2. Academic decline: Falling grades and inability to concentrate fuel further parental distress.
    3. Financial stress: Unexpected credit card bills or loans worsen family relations.

    The Limits of Gaming Bans

    1. Immediate relief: Bans reduce household conflicts and financial shocks.
    2. Partial bans & age-gating: Allowing adults while protecting minors can delay addiction onset.
    3. Psychological displacement: Without therapy, children may shift to pornography, substance abuse, or compulsive social media use.

    Towards a Comprehensive Strategy Against Gaming Addiction

    1. School-based interventions: Routine mental health screenings and workshops on digital addiction.
    2. Parental guidance: Training parents to spot early warning signs and encourage healthy digital habits.
    3. Child-friendly counselling: Access to therapy services designed for adolescents.
    4. Awareness campaigns: Multi-stakeholder efforts targeting students, caregivers, and teachers.

    Gaming Addiction as a Behavioural Health Challenge

    1. Beyond discipline: Punishment or restriction alone worsens secrecy and aggression.
    2. Long-term healing: A behavioural approach can repair family rifts and promote healthy tech use.
    3. Balanced future: Children should grow up with resilience, not dependency, in digital spaces.

    Way Forward: Towards a Balanced Approach

    1. Public Health Lens: Treat gaming addiction as a behavioural health issue with school screenings, awareness drives, and accessible counselling.
    2. Smart Regulation: Use age-gating, spending caps, and parental consent instead of blanket bans.
    3. Global Lessons:
      • China: Strict weekly limits → relief but drove youth to unregulated platforms.
      • UK/EU: Regulate loot boxes as gambling → targeted, flexible control.
      • South Korea: Late-night gaming ban + rehab centres → balance of restriction and support.
    4. India’s Path: A middle way combining safeguards with education and digital literacy, avoiding both overregulation and laissez-faire neglect.

    Conclusion

    India’s youth deserve more than prohibitionist measures. A firewall can block access, but not heal emotional wounds. True protection lies in combining thoughtful regulation with robust mental health programmes, counselling, and awareness. Only then can families find balance and children grow with a healthier relationship to technology.

    PYQ Relevance

    [UPSC 2023] “Child cuddling is now being replaced by mobile phones. Discuss its impact on the socialization of children.”

    Linkage: Online real-money gaming, like mobile phones, is replacing natural child–parent interaction with addictive digital engagement. This weakens socialization, fuels secrecy and conflict within families, and erodes trust. Both highlight how technology-driven dependence disrupts healthy emotional development in children.
