Science A-Z (RAZ科学版,很棒的科普类分级读物)全套资料[音频+视频+PDF+部分教案+练习册]

除了RAZ，其实还有很多其它分级读物，这套ScienceA-Z，也叫SAZ，也相当于是RAZ的孪生姐妹花。

一、Science A-Z

Learning A-Z旗下有很多套分级读物，除了我们熟知的Reading A-Z, Raz kids,还有Writing A-Z, Vocabulary A-Z, Science A-Z等。

Reading A-Z：也叫做RAZ，根据全文词汇数、高频词词汇数与比例、低频词词汇数与比例、句子长度、句子复杂度、句式、插图信息量、思想深度、主题等多个角度，将整个阅读体系分为aa，A-Z 27个级别。

Raz-Kids：根据难易程度从aa-Z2分为29级，每个级别有十几本到几十本的书。

Writing A-Z：也叫做WAZ,是RAZ体系下的写作教学。 首先分为四大文体，分别是：1、Informative Explanatory(说明文)；2、Narrative(记叙文)；3、Opinion Argument(议论文)；4、Transactional(应用文)。

Vocabulary A-Z：也叫做VAZ，针对的主要是高频词汇的练习。

Science A-Z：就是今天要测评的SAZ，它包含四大领域主题，分别是Life, Earth, Physical, Process，每个领域的主题是按年级划分，分别是GK-2，G3-4，G5-6，我们下面就来重点讲一下。

SAZ细分14 个年级主题，每个年级下的读物分成low, middle和high三个等级。它按主题划分成四大领域，分别是 Life, Earth&Space, Physical, Process。

Science A-Z的K-6级别中的low, mid, high都有对应的Learning A-Z的分级体系，蓝思值和 Fountas&Pinnell分级系统。

补充一句，前面提到的，孩子如果在阅读同体系下的RAZ，至少要阅读到E级别才能入门SAZ。如果家长对自己的孩子基础不是很了解，不要盲目选择。

二、Science A-Z读物版块内容分析

以GK-2级别下的同一主题Animals为例，给大家做一个分析。SAZ的这个主题总共有3个级别可以选择，如下图所示 ：

测评后发现同一主题low, mid, high三个等级的难度不断加大，low到mid的梯度呈缓慢递增的梯度，而mid到high的难度递增幅度较大。

从文本的容量和句子重读性看，文本总单词数从60增加到195再到469，句子从2-3句的固定句式升级到4-5句固定句式再到段落式文本，对孩子的阅读要求是越来越高的。

三个等级虽然从文本容量，句型重复性，单词难度等方面不断提升，但low, mid, high同一主题的中心主旨都是不变的，如Animals这个主题下的三个等级的读物都是在阐述同一主旨—动物的共性和特性。

很友好的一点是每本读物都很清楚标记了蓝思值的具体数值和Learning A-Z的级别，家长可以同时根据这两者去判断这本读书是否适合自己的孩子。

进去选择了之后，我们开始正式的读书版块内容分析。

版块内容1——Book quiz：相当于一个小的趣味测试题，根据前面的内容来侧面考察孩子的掌握情况。

版块内容2——Digital：在线练习，综合考察了孩子的听说读写能力，比如一些小功能也十分有趣。

录音、画笔、生词本，一串连贯的功能机制下来，让孩子能很好的回顾读物内容，形成一个完整的学习闭环。

版块内容3——Project：这部分主要针对教师在教学过程中使用，画笔，鼠标，高亮，清除，标注等功能不一而足。

从内容设计上看，版块的规划是十分清晰合理的，内容上的学习既设计了音频和录音，也配套了练习题，要求孩子不仅能阅读，还需要深度理解文本内容。且画笔，生词本这些功能也增强了趣味性。

三、学习建议

最后给大家附上一张SAZ的各级别难度与蓝思值对照表。

SAZ的整个跨度从蓝思200L一直到1100L。所以基本上RAZ读到E之后，才能进入SAZ的学习，最难的部分直追RAZ的X级别。因此这部分的内容要好好利用，学完也是一个浩大的工程。

总体看，Science A-Z这套科普类读物分级严谨，但对孩子的英语水平要求较高，不适合零基础的孩子入门。

如果孩子在读同体系的RAZ，可以在E阶段加入Science A-Z的读物，nonfiction也是孩子读物材料中不可或缺的一部分， 不能因为难度大或孩子不爱读就直接舍弃，需要同时兼顾fiction和nonfiction。

Science A-Z科学的知识体系，全方位多角度地引入儿童认知百科，探索世界。

200个门类、超过1000个儿童必备百科知识点；并走遍世界各地，精心拍摄各种灵活、生动的高清照片，辅以专业画家手绘特写精致插图。

并配套有词汇英英释义卡、单元测试、科普拓展内容等。

整个体系图片超过3000张，用儿童喜爱的方式讲述科学，让每个儿童都享受阅读。
