…United States is only a year or two old today. The Common Core was an attempt to introduce coherency and logical progression into the mishmash of topics that characterized "reform math" textbooks such as Everyday Math (which is probably the best and most mathematically sound of the reform math textbooks) and TERC: Investigations, among other titles. The Common Core standards are generally regarded, as curriculum standards,…
……而且：(a + b) * (c + d) = ad + bc + ac + ad 也同样成立。哇哦！现在再画个网格和一堆线，就能把买书的人忽悠得团团转了。参见 [1]。为了让我孩子的学校考虑换掉教材，我把《Everyday Math》这门课研究得比谁都透彻。《Everyday Math》跟其他课程一样，也是基于某大学教育系的研究成果搞出来的。这所大学……

My second grader has a ton of anxiety over the confusing and disorganized lessons & homework that are coming out of the "Everyday Math" textbook that his teacher is using. Hmm, I wonder who wrote this Everyday Math curriculum...oh, look at that. It's the University of Chicago. (And yes, I'm opening that door.)
…Mars and build microchips yet we can't teach our kids math effectively. I have seen these books, I have seen this "everyday"-type approach to math also in college for non-technical majors. I looked at Everyday Math links. They are a disaster. It is simpler to explain the goddam subject than to find round-about "simple" problems and "games" that somehow distantly refer to math but are meant to be "easy" when in…
……这其实跟 Common Core 没什么关系。不同学区自行采购并推行的各种教材，在实现 Common Core 目标的路径上大相径庭。另一条评论里提到的《Everyday Math》大部分时候烂得不行，但用得却相当广泛。我们今年夏天正打算搬到我妻子工作学区里的房子，免得我儿子去上那种……
…This really doesn't have anything to do with common core. Different curriculums that the school districts choose to purchase and implement go about achieving the goals of common core quite differently. Everyday Math is mentioned in another comment and is mostly awful. It's pretty widely used though. We are actually moving to a house in my wife's school district this summer so that our son doesn't go to school where…
……“教育”专业人士和学者。这些课程没有去教一套经过充分检验的运算（加法、减法等）方法，反而抛出一堆花里胡哨的“替代算法”。在《Everyday Math》（我家孩子学的就是这套）里，根本不教乘法和除法的标准算法，而是花了好几年用那些另类（且更低效）的方法反复操练。这导致学生变得犹犹豫豫……

……美国如今也才实行了一两年。Common Core 是为了把连贯性和逻辑递进带入到那堆大杂烩主题中，而这种大杂烩正是《Everyday Math》（这大概算是“数学改革”教材里最好、数学上最严谨的一套了）以及《TERC: Investigations》等教材的典型特征。Common Core 标准通常被视作课程标准……

我读二年级的孩子因为老师用的《Everyday Math》教材里混乱不堪、毫无章法的课程和作业，焦虑得不行。嗯，我很好奇是谁编了这套《Everyday Math》课程……嚯，你瞧瞧，芝加哥大学。（对，我就是要开撕这个。）

……能上火星还能造芯片，却连把数学教好都做不到。我见过这类书，大学里给非理工科专业教数学也是这种“日常生活”式的套路。我看过《Everyday Math》的那些链接，简直就是灾难。直接把这门该死的学科讲明白，远比去拐弯抹角搞一堆看似跟数学沾点边、号称“简单”但实际上……的“简化”问题和“游戏”容易得多。
