As a mathematics professor, I would hear my students say, “I understand you in class, but
when I get home I am lost.” When I would probe further, students would continue with
“I can’t read the book.” As a mathematician, I always found mathematics textbooks quite
easy to read—and then it dawned on me: Don’t look at this book through a mathematician’s
eyes; look at it through the eyes of students who might not view mathematics the same way
that I do. What I found was that the books were not at all like my class. Students understood
me in class, but when they got home they couldn’t understand the book.
It was then that the folks at Wiley lured me into writing. My goal was to write a book
that is seamless with how we teach and is an ally (not an adversary) to student learning.
I wanted to give students a book they could read without sacrificing the rigor needed for
conceptual understanding. The following quote comes from a reviewer when asked about
the rigor of the book:
I would say that this text comes across as a little less rigorous than other texts, but
I think that stems from how easy it is to read and how clear the author is. When one
actually looks closely at the material, the level of rigor is high.
DISTINGUISHING FEATURES
Four key features distinguish this book from others, and they came directly from my
classroom.
PARALLEL WORDS AND MATH
Have you ever looked at your students’ notes? I found that my students were only scribbling
down the mathematics that I would write—never the words that I would say in class. I started
passing out handouts that had two columns: one column for math and one column for words.
Each example would have one or the other; either the words were there and students had
to fill in the math or the math was there and students had to fill in the words. If you look at
the examples in this book, you will see that the words (your voice) are on the left and the
mathematics is on the right. In most math books, when the author illustrates an example,
the mathematics is usually down the center of the page, and if the students don’t know what
mathematical operation was performed, they will look to the right for some brief statement
of help. That’s not how we teach; we don’t write out an example on the board and then say,
“Class, guess what I just did!” Instead we lead our students, telling them what step is coming
and then performing that mathematical step together—and reading naturally from left to
right. Student reviewers have said that the examples in this book are easy to read; that’s
because your voice is right there with them, working through problems together.

    听闻英语是外教教的,很专业的,对于道听途说我是一直不是很相信,多方打听了好多的人,想给孩子找一个好点的平台,后来还是选择咨询一下英语,看看教学模式什么的是不是那么回事,前两天试听了一节课,感觉还可以,报了一个月的课程,看看效果再说吧。

    为了孩子的英语辅导,跑了好多家的英语教育机构,之前也也给他报过实体的培英语训班,效果一直不是很好的,而且他很抵触,老是哭闹的,像是被逼的一样,后来也是朋友介绍的在英语这边报的班,开始看到外教老师的时候他很感兴趣,加上老师一点点引导的他越来越能跟上老师的节奏了,现在一提晚上的课程,他可开心了,我也是很开心呢。

    我家孩子在英语上学习呢,这段时间来表现的不错的,口语进步很多的, 跟小朋友们在一起玩耍的时候会时不时的说出几句真八经的英语来,作为妈妈我很欣慰自己家的孩子比别的小朋友优秀,孩子的教育问题是大事,找好的教育平台才是真理。

    前几天在超市买菜都看到了英语的广告,真的是无处不在,逐渐的,英语这个品牌就给我留下了深刻的印象,正好我也想给孩子报名英语培训班,借此就给去他们领取了一节试听课程,跟大家分享一下。我和我们家孩子一起上过英语的试听课,孩子特别喜欢,可能是老师是外国人吧,很有新鲜感,而且上课内容也挺生动的,孩子挺喜欢的,最近也在考虑给孩子报一个班

    "一个一对一英语培训机构吧,其他的不是很清楚呢,感觉一对一培训方面李阳易说堂名气更大一些,口碑也挺不错,听说有免费体验课的,可以去试试。"

    孩子上网再也不玩游戏了,英语在线学习呢,外教讲课太有吸引力了。
