Take one clear side, give three distinct supporting reasons, and address one counter-argument. Do not use the phrases 'in conclusion' or 'in today's world'.", "output": "The presence of smartphones in secondary schools has transformed classrooms from hubs of learning into battlegrounds for student attention. To restore academic focus and foster healthier social environments, secondary schools must implement a complete ban on smartphones during the school day.\n\nFirst, banning smartphones significantly improves academic performance. The constant barrage of notifications, texts, and social media updates creates a state of continuous partial attention. Research consistently shows that even the mere presence of a silent phone on a desk reduces cognitive capacity. Without these digital distractions, students can deeply engage with lessons, leading to higher comprehension, active participation, and better test scores.\n\nSecond, a phone-free policy encourages genuine social interaction and protects student mental health. When phones are permitted, lunchrooms and hallways fall silent as students stare at screens, exacerbating feelings of isolation. Removing phones forces students to converse, build empathy, and develop essential face-to-face communication skills vital for their future. Furthermore, it curtails school-hours cyberbullying, providing a daily sanctuary from online social pressures.\n\nThird, a ban relieves teachers of the exhausting role of digital gatekeepers. Educators currently waste valuable instructional time constantly telling students to put their devices away. A clear, school-wide ban establishes a uniform standard, eliminating daily classroom friction and allowing teachers to focus entirely on pedagogy rather than policing screen time.\n\nOpponents argue that smartphones are necessary for safety, allowing parents to contact their children during emergencies. However, this concern is easily resolved. School administrative offices remain fully capable of relaying urgent messages instantly, just as they did for decades. Moreover, constant parental access during the school day often fosters anxiety and dependency rather than the independence teenagers need to develop.\n\nUltimately, the school day should be a dedicated space for learning and personal growth. By removing smartphones, schools can cultivate deeply focused minds, stronger peer relationships, and more effective teaching environments. It is time for educational institutions to prioritize student well-being over constant digital connectivity.", "latency_ms": 15761, "cost": 0.0242685, "task_score": 5, "judges": [ { "judge": "anthropic/claude-sonnet-5", "score": 9, "violates": false, "reasoning": "Clear stance, three distinct reasons, addresses counter-argument, avoids banned phrases, well-written and close to 350 words." }, { "judge": "openai/gpt-5.6-terra", "score": 5, "violates": true, "reasoning": "Clear, well-structured argument with three distinct reasons and a counterargument.
