第20期 · 孩子到底该不该有家庭作业

Few educational practices are as universally loathed by their intended beneficiaries as homework. Across the globe, kitchen tables become battlegrounds, and the phrase 'have you finished your homework' echoes through millions of households each evening. Yet the durability of homework as an institution suggests that its value cannot be dismissed as mere pedagogical inertia. I believe that homework, when thoughtfully designed and judiciously assigned, remains a valuable educational tool — but the volume and nature of homework as currently practised in many school systems has veered far from this ideal, burdening children without commensurate benefit. The case against homework has gathered considerable momentum in recent years, fuelled by mounting evidence and shifting cultural attitudes toward childhood. A landmark study by Stanford University found that students who spent more than two hours on homework per night reported elevated levels of stress, physical health complaints, and alienation from family life — without any measurable improvement in academic performance. The mechanism is intuitive: children, particularly younger ones, have finite reservoirs of attention and emotional resilience. Exhausting these during the school day and then demanding further concentration in the evening is a recipe for burnout, not brilliance. Moreover, homework exacerbates inequality. Children from affluent households benefit from quiet study spaces, internet access, and parents with the time and expertise to assist. Their less privileged peers, by contrast, may be sharing cramped living quarters with multiple siblings, juggling part-time jobs, or caring for younger family members — making homework an amplifier of disadvantage rather than an equaliser of opportunity. Advocates of the 'no homework' position, pointing to Finland's top-ranking education system where homework is minimal, argue that meaningful learning happens in the classroom under the guidance of a skilled teacher, not in solitary, often frustrated, evening labour. Nevertheless, to jettison homework entirely would be to discard a tool whose value depends far more on its design than on its mere existence. The distinction between mindless repetition and deliberate practice is crucial. Well-designed homework — such as reading for pleasure, which builds vocabulary and empathy in ways no classroom exercise can replicate, or project-based assignments that invite children to interview grandparents about family history — extends learning beyond the curriculum's confines and fosters intellectual curiosity. At the secondary level, homework serves an additional function: it cultivates the self-discipline, time management, and independent study habits that are prerequisites for success in higher education and professional life. A student who arrives at university having never managed their own workload outside a supervised environment is being set up for a rude awakening. The question, then, is not whether homework should exist, but what kind of homework, how much, and for whom. A ten-minute reading assignment for a seven-year-old is qualitatively different from three hours of drill exercises for a sixteen-year-old — and educational policy must reflect this spectrum rather than adopting a one-size-fits-all stance. In conclusion, homework is neither the indispensable pillar of academic rigour that its staunchest defenders claim, nor the developmental toxin that its most vocal critics allege. It is a pedagogical instrument whose effectiveness hinges on dosage and design. The evidence suggests that excessive, repetitive homework is counterproductive—harming well-being, widening inequality, and yielding negligible academic returns. Yet high-quality, age-appropriate homework can reinforce classroom learning, nurture independent study skills, and enrich the curriculum in ways that the school day alone cannot accommodate. The path forward lies not in abolition but in recalibration: shorter, more purposeful assignments for younger children; increasing autonomy and complexity as students mature; and a fundamental shift from measuring homework by hours logged to evaluating it by learning catalysed. A child who reads a chapter of a novel out of genuine curiosity has done more valuable homework than one who has mechanically completed three worksheets in resentful compliance.
