KS3计算 E-Safety 数字素养 八主题 举报路径
KS3 的计算课里，网络安全常被排在编程与算法之后，像是课程末尾的附加话题。翻一下国家课程大纲就会发现，它和安全、责任、举报写在同一段要求里，与算法同级。这篇文章按官方文件的顺序梳理 KS3 需要掌握的内容，并把每一条落到课堂上或家里能执行的动作上。读完之后，学生应该能说清三件事：风险有哪几类、自己的账号该怎么设、遇到问题时报告给谁。
Online safety often sits at the end of a key stage 3 computing scheme of work, treated as a bolt-on after programming and algorithms; the national curriculum places it in the same bullet list as computational thinking, which suggests a different priority. What follows takes the official documents in order and turns each element into something a school or a family can act on. By the end, a pupil should be able to name the categories of risk, describe how their own accounts are set up, and say who they would report a problem to.
国家课程对 KS3 计算的三条硬要求
英格兰的国家课程计算学科大纲在 2013 年 9 月公布，从 2014 年 9 月起成为法定要求。KS3 那一条的原文写得相当具体：学生要理解一系列安全、尊重、负责且稳妥地使用技术的方式，包括保护自己的网络身份与隐私。后半句还有两个动作，识别不恰当的内容、接触与行为，并且知道遇到问题时怎么举报。这三项经常被当成一句口号带过，其实每一项都能拆成可检查的学习任务。很多学生以为网络安全就是不要点陌生链接，实际考的是判断与处置能力。老师批改单元作业时看到的差距也在这里，能背下四个形容词的不少，能说清举报路径的不多。所以这一条在课上是能落地的，并不抽象。
The key stage 3 programme of study for computing was published in September 2013 and became statutory from September 2014. Its online safety bullet asks pupils to understand a range of ways to use technology safely, respectfully, responsibly and securely, including protecting their online identity and privacy; it then adds two moves that are easy to skim past, namely recognising inappropriate content, contact and conduct and knowing how to report concerns. Each of those elements can be turned into a checkable classroom task, which is why the bullet rewards teaching that goes past a warning about unknown links.
数字素养不是会用软件而是能判断
同一份大纲的宗旨段给这门课下过一个定义，说计算学科要让学生成为有数字素养的人，能够用信息与通信技术表达并发展自己的想法，达到适合未来职场的水平。这里的关键词是表达，不是操作。会用五个软件不等于有数字素养，能把一个问题讲清楚、找到合适的工具、判断结果可不可信，才算。学校排课时容易把数字素养压成软件操作课，学生也乐于接受，因为操作有明确的完成标志。常见的错误是把熟练当成理解，按钮点得很顺，却说不清数据去了哪里。KS3 阶段真正的分水岭，是学生开始追问工具背后发生了什么。这个追问习惯一旦建立，后面学任何新平台都省力。反过来，只练操作的单元做完之后几乎不留下迁移能力。
The purpose of study statement in the same document defines computing as helping pupils become digitally literate, able to use information and communication technology to express themselves and develop their ideas at a level suitable for the future workplace. The operative word is express rather than operate. Fluency with five applications is not the same as being able to frame a problem, choose a suitable tool and judge whether the output can be trusted, and that gap is where most schemes of work lose their value.
内容接触与行为三个风险面
国家课程用的三个词是内容、接触与行为，这与保护领域常用的分类同源。内容指学生看到的东西，包括暴力、仇恨与自伤相关的材料。接触指与学生互动的人，包括陌生人搭话、诱导与网络勒索。行为指学生自己或同伴做出的举动，包括欺凌、转发与留下不当记录。官方 safeguarding 文件在这三层之外还加了商业与合同这一层，指向付费陷阱与数据被商业利用。分类的价值在于定位问题，同一张截图可能是内容问题，也可能是行为问题，处理方式完全不同。很多学生以为风险只来自陌生人，实际上同伴之间的转发更容易造成持续伤害。老师在做事件记录时，先归类再定处置，比直接按严重程度排序更稳。
The national curriculum uses three words, content, contact and conduct, which map onto the categories used across safeguarding guidance. Content covers what a pupil sees, contact covers who is interacting with them, and conduct covers what pupils themselves or their peers do, including bullying, forwarding and leaving a damaging record. Naming the category first makes an incident easier to handle, because the same screenshot can raise a content question or a conduct question with quite different responses.
UKCIS 八个主题与年龄分档
英国互联网安全委员会在 2018 年 2 月首次发布《Education for a Connected World》，2020 年 6 月更新为现版。这份框架把网络素养教育拆成八个主题：自我形象与身份、网络关系、网络声誉、网络欺凌、信息管理、健康与生活方式、隐私与安全、版权与所有权。每个主题再按 4 至 7 岁、7 至 11 岁、11 至 14 岁、14 至 18 岁四档写出具体的学习结果。它的用途不是新增一门课，而是拿来审计现有课程有没有缺口。KS3 对应 11 至 14 岁那一档，动词落在能够描述、能够解释、能够评估。用这张表对照自己的单元设计，比凭印象判断靠谱得多。学校做课程地图时，这张表几乎是最省事的起点。
The UK Council for Internet Safety first published Education for a Connected World in February 2018, with the current edition dated June 2020. The framework splits online education into eight strands, from self-image and identity through online relationships, reputation, bullying, managing information, health and wellbeing, privacy and security, to copyright and ownership, and it writes learning outcomes for four age bands. Its practical use is as an audit tool rather than an extra timetable slot, and the 11 to 14 band lines up with key stage 3.
教育部指导文件的两种用法
英国教育部官网在 2019 年 6 月 26 日发布《Teaching online safety in schools》，2023 年 1 月 12 日更新过一次。文件性质是非强制的，适用英格兰的公立学校、学院与自由学校，明确说要嵌入现有科目，不额外增加教学内容。它点出的嵌入位置是关系与健康教育、公民科与计算。2023 年那版把网络激进化与网络诈骗写进了风险清单，还补了假网站与诈骗邮件的识别。学校常见的做法是把这块内容塞进计算机课的一个单元，然后当作完成。官方口径其实要求全校一致，政策、员工培训、课程与家长沟通都要提到。督导时被追问的往往正是后面这几项，而不是课上得好不好。
The Department for Education published Teaching online safety in schools on 26 June 2019 and updated it on 12 January 2023. The document is non-statutory and applies to maintained schools, academies and free schools in England; it asks schools to embed the content in existing subjects rather than adding new requirements, pointing to relationships and health education, citizenship and computing. The 2023 revision added online radicalisation and online fraud to the list of harms, together with recognising fake websites and scam emails.
网络身份与隐私的实际设置
KS3 学生最常见的失守不是被高手攻破，而是密码复用与过度分享。一个密码走遍所有平台，任何一站泄露就等于全部失守。可以落地的做法是学习类账号用长口令加二步验证，社交账号不要与邮箱同密码。个人信息最小化同样具体，用户名不要带真实姓名与出生年份，头像不要露出校服校徽与门牌号。位置信息默认关闭，发照片前看清背景里的地标。这一步最容易偷懒，因为平台的默认设置往往就是分享给所有人。改成仅好友可见只要半分钟，但很多账号从注册那天起就没动过。抽十分钟翻一遍旧帖子的权限，通常比学一个新工具更有用。
What undoes most key stage 3 accounts is not a skilled attacker but password reuse and over-sharing. One password across every platform means a single breach opens everything, so long passphrases plus two-step verification on school accounts, and a different password from the email account on social ones, are the cheap fixes. The same logic applies to personal data, since a username carrying a real name and a birth year, or a profile photo showing a school badge, is information nobody needed to publish.
网络欺凌与举报的先后顺序
网络欺凌与线下欺凌的差别在持续性与传播速度，一条消息几分钟内就能被截图转发到好几个群。学校的 safeguarding 指导要求有清晰的举报渠道，学生要知道向谁报告。保存证据是第一动作，截图带上时间与账号名，不要先删对话。第二动作是停止互动，不回击、也不拉更多同学进群看热闹。第三动作才是举报，校内有指定负责人，校外的求助渠道包括 Childline 的 0800 1111 与警方网络举报入口。很多学生以为删掉就没事，实际删除会破坏证据链，也让后续处理更难。旁观者在这里能起作用，转发前停三秒往往就阻断了扩散。
Online bullying differs from the offline version in persistence and speed, since a message can be screenshotted into several group chats within minutes. Keeping evidence comes first, with timestamps and account names captured before anything is deleted; then comes stepping out of the exchange rather than replying; reporting to a named member of staff follows. Deleting the thread feels like a solution but destroys the evidence a school needs, which is a point pupils routinely miss.
信息辨识的三步核查
信息管理这个主题在 KS3 要练的是可核查的判断，不是背一份假新闻清单。可以固定成三步，先看谁写的，再看什么时候写的，最后看有没有第二个独立来源印证同一件事。三步里最容易跳过的是第二步，旧闻被当成新闻传播是很常见的现象。图像与视频现在需要额外一层怀疑，生成式工具可以让一段没说过的话配上真实人脸的嘴型。官方对平台的义务写在 2023 年《在线安全法》里，平台要处理非法与有害内容，但这不意味着用户不必判断。常见的错误是只看画面像不像，而不去查原始出处。把同一段视频做一次反向搜图，很多时候能直接找到最早发布的那条。这一步花的时间，通常比在评论区争论少得多。
Managing online information at key stage 3 is about repeatable checks rather than memorising a list of fake stories. Three questions cover most cases, who wrote it, when it was written, and whether an independent source confirms the same claim, and the date is the one pupils skip most often. Images and video now need an extra layer of doubt, because generative tools can put words into a real face, and a reverse image search resolves more cases than an argument in the comments.
数字足迹与在线声誉
在线声誉这个主题在 11 至 14 岁档的要求，是能够描述别人可能怎样用网络信息来判断自己。这个年龄的学生开始留下可被搜索的记录，比赛报名、社团主页、公开的评论区发言都算。截图可以脱离语境传播，一句玩笑三年后可能出现在完全不同的场合。实操上建议把账号分成两类，一类给学校与申请用，一类是私人的，两边内容不交叉。搜一次自己的名字与常用用户名，看看首页出现什么，这件事很多学生从没做过。常见的错误是以为删帖就等于消失，缓存与转载往往还在。与其事后补救，不如在发布前想清楚这条记录五年后还愿不愿意被看到。
The online reputation strand for the 11 to 14 band asks pupils to describe how others might use online information to judge them. By this age a searchable record is already forming through competition entries, club pages and public comments, and screenshots travel without their context. Running a search on your own name and usual username once a term is a small habit that surfaces problems while they are still fixable.
睡眠优先的屏幕时间管理
健康与生活方式这个主题关注的不是把屏幕时间压到某个数字，而是屏幕使用有没有挤掉睡眠、运动与面对面社交。KS3 学生最直接的证据通常出现在睡眠上，睡前刷半小时手机，入睡时间会明显推迟。可执行的规则比时长限制有效，比如卧室不放充电器，睡前一小时把设备放到客厅。通知权限是另一个被低估的开关，关掉非必要推送之后，主动打开应用的次数会下降。很多学生以为自己在同时处理多件事，实际是在任务之间反复切换，效率更低。老师能看到的结果，是深夜赶出来的作业质量明显下降。先修睡眠再谈时间管理，顺序反了通常两头都做不好。
The health and wellbeing strand is less about hitting a screen time number than about whether screen use has displaced sleep, exercise and face to face contact. For key stage 3 pupils the clearest evidence shows up at bedtime, where half an hour of scrolling delays falling asleep, and notification settings often matter more than a timer. Fixing sleep first and time management second tends to work; the reverse order usually fails at both.
版权与所有权的两条线
版权与所有权这个主题在 KS3 要讲清两件事，别人的作品怎么合法使用，自己的作品怎么被保护。课堂作业里引用图片、音乐与代码都需要说明出处，学校通常按教学例外处理，但公开发布就超出了这个范围。下载与分发盗版资源的法律后果，在官方材料里写得相当直接。生成式工具带来了新的模糊地带，用 AI 生成的文字或图像在作业里要不要标注，各校政策不同，标注始终是更安全的选择。常见的错误是把网上找到的东西默认当成公共资源。注明来源与许可，比事后解释省事得多。
The copyright and ownership strand covers two lines at once, how to use other people's work lawfully and how to protect your own. Quoting images, music and code in classwork requires attribution, and the teaching exception schools rely on does not extend to publishing the same material publicly. Generative tools have blurred the line further, and labelling AI assisted work is the safer choice wherever a school policy is silent.
学校过滤监控与家长知情
《Keeping children safe in education 2026》从 2026 年 9 月 1 日起生效，其中过滤与监控那几段给出了学校必须做到的事。学校要明确谁负责过滤与监控，至少每学年审查一次有效性，并保留检查记录。过滤要在不影响教学的前提下拦下有害内容，监控策略要能覆盖实际的 safeguarding 需求。英国教育部另外发布了过滤与监控标准，学校可以用官方自评工具逐项对照。家长这一侧的权利是知情，学校用什么系统过滤与监控，孩子在校被要求访问哪些网站，与谁在线互动。这一点最容易被家校沟通忽略，家长往往只知道有过滤，却不知道具体规则。
Keeping children safe in education 2026 came into force on 1 September 2026, and its filtering and monitoring paragraphs set out what schools must do, including assigning named responsibilities, reviewing effectiveness at least once every academic year and keeping a record of those checks. The Department for Education publishes separate filtering and monitoring standards with a self-assessment service. Parents are entitled to know which systems a school uses and which sites their child is asked to access, and that briefing is the part most often skipped.
