背单词,更容易一点! 弱记忆轻开局,刷视频强复习 背单词,其实不必痛苦。 大多数背单词软件,把“第一次学习”做得太重: 一次性要求记住拼写、例句、同义词,甚至词根词缀。 对成年人、孩子、中老年都太困难,也太反人性。 本应用使用一种更容易坚持的方法: 轻记忆开局 × 刷视频强复习 × 多感官刺激 × 低压力节奏 让你第一次真正感受到——背单词可以不焦虑,而且真的坚持得下去。 一、轻记忆开局:第一次见面不要求“全记住” 传统方法的问题,是第一次接触单词时塞太多信息,认知负担过高,第二天很容易“背了就忘”。 我们把步骤拆得更小,让记忆更符合遗忘规律和间隔重复(SRS)的节奏: 第一次只认识核心词义 + 发音 暂时不要求记例句、不要求记同义词 拼写会在后续复习中自然熟悉 孩子、中老年都能轻松起步 减少抗拒,让你“愿意开始” 你会发现:当第一次的压力降低了,记忆反而更牢。 二、视频强复习:30 秒记忆刺激,让复习变得“好刷” 背单词是否成功,不看第一次记得多牢,而看后面的复习质量。 本应用通过自动生成的 30 秒复习短视频,把当天需要复习的词汇编进超短故事: 你可以: 让自己出现在视频里 让孩子喜欢的形象、卡通人物出现 用形象生成工具捏出自己理想中的角色 选择场景:童话 / 太空 / 校园 / 旅行 / 商务 / 日常生活 自动把今天要复习的 6 个词融入故事 一条 30 秒的视频包含: 本人带入 画面刺激 人物情绪 单词含义 情境线索 多次重复 学习从“硬撑刷题”,变成“自己想点开”的轻复习。 多次刷同一条视频,就是在做主动回忆和重复接触,多感官一起参与,记得更牢、忘得更慢。 三、适合不同人群:孩子、学生、上班族、中老年 儿童(需家长监管) 孩子看到“自己在视频里出现”,天然就有参与感 复习时长固定,不做娱乐推荐流,不容易沉迷 家长可以控制节奏,只把它当成学习工具,而不是短视频软件 学生 / 上班族(应试 + 进阶) 大量词汇、时间零碎,需要的是“轻负担 + 高重复” 适合四六级、考研、雅思托福、出国、职场英语等场景 用短视频 + 填空 + 短句练习,把词反复带出来使用 中老年(注意力较弱) 一次记不住没关系,每天看几条熟悉、轻松的复习视频就够了 不需要长时间盯着屏幕,只要能坚持“小步走,走得久” 重点是能记住生活、旅行、简单交流常用词 在海外生活的中文用户 超市、餐厅、问路、简单聊天,只要先能说出单词就够用了 通过场景视频记住实际会用到的单词,而不是一大堆暂时用不到的生词 四、记忆工具箱:只保留真正有用的功能 我们刻意避免堆砌复杂的“炫技功能菜单”,只保留与记忆真正相关的部分: 单词谐音提示(适合记首印象) 联想记忆(故事 / 图像联想) 简易语境句(给出最常用的那一种用法) 多轮复习提醒(节奏轻,不制造压力) 学习节奏规划(帮助你形成自己的复习习惯) 单词困难点提示(告诉你这个词容易混淆在哪里) 每天 3–10 分钟,就可以完成一次完整的轻复习。 我们用“轻任务(micro-task)”的方式,把难事拆成小块,让你长期坚持而不是一时冲动。 五、隐私与安全:内容归你,权限尽量少 视频和图片归用户所有 只在学习流程中短期保存,需要时可随时删除 不做不必要的长期存储 不请求不必要的手机权限 不做外部推荐流,不抓取无关数据 我们希望这是一个“干净的学习工具”,而不是又一个让人停不下来的娱乐软件。 如果你曾经多次尝试背单词,却总是“背了又忘、开始又放弃”, 可以试试这种:先减轻记忆负担,再用有趣的方式多次复习 的路线。 让轻记忆负责“迈出第一步”, 让视频强复习负责“陪你走完全程”。
