Interesting Article about Math in the World Today.

The article is pretty spot on. This is probably the largest root cause:

One likely reason: U.S. high schools teach math differently than other countries. Classes here often focus on formulas and procedures rather than teaching students to think creatively about solving complex problems involving all sorts of mathematics, experts said.

I highly doubt the above will change anytime soon. Most teachers and parents do not even know what mathematics is, they think it is procedural and rote and it's all about calculations. In fact the exact opposite is true. Math is about imagination, creativity, problem solving and proof (i.e the art of explanation). In general our culture does not support thinking deeply and creatively about things, it instead opts for acceleration coupled with a superficial understanding (certainly in math class, if not in school in general). As a teacher, I can find and pose numerous examples of elementary problems (i.e given/shown to elementary students and only requiring the most basic tools) to many high school students and they would have a very hard time solving them, or not be able to at all. This proves that problem solving in our math classes is almost nonexistent, which is corroborated by the abysmal average SAT scores nationwide.

Oh, and the "geometry sandwich" is absolutely real:

Most American high schools teach algebra I in ninth grade, geometry in 10th grade and algebra II in 11th grade – something Boaler calls “the geometry sandwich. Other countries teach three straight years of integrated math – I, II and III — in which concepts of algebra, geometry, probability, statistics and data science are taught together, allowing students to take deep dives into complex problems.”

The lack of understanding of geometry (by both students and teachers) is so bad that it was hilariously featured in a chapter from a famous problem solving book a couple of years back called "Geometry for Americans" :

Although MCPS still calls the sequence Algebra 1, Geometry, Algebra2 it actually is integrated math and should be renamed--there are algebra topics all three years, there are geometry topics all three years. Plenty of other districts actually have renamed the classes. Plenty of other school districts, e.g. California, have renamed the classes. Now, the topics covered in MCPS are more cursory compared to what was covered in algebra/geometry a generation ago, but students are hitting the classes younger--the target is 80% in Algebra 1 by 8th grade.

There's plenty wrong with math education in the US but the article sounds out of date.

I do agree that in previous years there was too much emphasis on formulas and procedures and not the whys, and 2.0 math in MCPS tried to address that. Unfortunately, the worksheets they used weren't great, and even some of the lower grade teachers were confused.

I got my kids a Singapore math book to help them understand the "new math".

There is definitely no geometry being done in algebra classes, that is a myth.

Singapore the country is moving away from Singapore math towards the way we teach math here in the US.

? I don't think they are going to teach math the way we do here in a sense that it's just rote and not explaining math well. We score lower than they do in the math PISA. But, I think they would include more creative thinking and questioning the whys, how the US encourages independent thought, in their way of teaching.

In the MCPS algebra packets, it's quite common to have a problem that looks at area or perimeter of a simple figure as a function of side length. These are concepts, introduced in IM and revisited in geometry. Later in the year there's some discussion of optimizing area given constraints on perimeter.

The bigger question is how much traditional geometry is in geometry. The unit on proofs is one packet and about three weeks, straight edge and compass constructions are about the same. But there are frequent problems that use algebra. E.g. there will be a figure with two unknown angles, and geometric relationships such that a system of two variables needs to be solved--algebra review.

Right but that's not really geometry, it's more of an algebraic afterthought. And constructions by themselves would not make sense without proving why the construction works, which is done using geometric principles. Those geometric principles (parallel lines, angles relationships, similar/congruent triangles, etc.) are not taught until geometry class. Without having these basics down, just doing a construction is akin to following a recipe without knowing why it works at all.

I also have reservations about proofs, I highly doubt an isolated proof unit will be helpful in understanding how to argue about what is/isn't true. Learning how to prove something (i.e. logically explaining why something is true via deductive reasoning) is something that should be done in all areas of mathematics throughout the school year (and kids in elementary school can handle it if developed correctly). Proof writing cannot be taught in a matter of weeks, since the development of the skill is highly dependent on doing lots of various types of problems from all subjects.

The Pisa test is given to 15-year olds. Those kids are in 9th grade and have just started high school. In many other countries high school is 10-12 only. So, nothing much to do with high school math and good test scores.
5th grade was when math instruction started to go down for us.

I don't disagree, but I'm not sure how familiar you are with the MCPS geometry curriculum. There's a little lip service to constructions, a little to proofs--which mostly amounts to filling in a blank in an otherwise completed two-column proof. In fact most of euclidean geometry is swapped out for studying transformations in the coordinate plane: translations, reflections, and rotations by 90 degrees (arbitrary angle is too advanced). This is all a ground work for studying functions, and a direct continuation of the way lines and parabolas are introduced in MCPS algebra 1. This is applied further in algebra 2. The course are taught on a spiral and topics are revisited and expanded each year.

I agree proofs could be incorporated through out math education, but they are not. My DC is in calc now, and still not seeing proofs--there are some in the book, but none presented in class. There are very few teachers with the experience to model proof technique, even the most basic. Concise definitions aren't modeled either, and that's necessary for proofs. There aren't even textbooks before pre-calc, so where would the teachers get clear definitions, much less the students. I know for a fact my DC's teacher last year didn't know that a counter example suffices to show a statement is false, DC almost lost points on a test because of it, and when arguing was told grudgingly there could be points this once.

Yup it's a sad situation, I guess I was griping about the fact that what they call geometry is really not teaching them to think geometrically at all and they really only do that in geometry class. Regarding your DC, it's definitely a culture and teacher issue. This is typically what happens when teachers are teaching math without having majored in math (or any other technical subject), some having only "education" majors.

The problem is that this is not only happening in high school which is bad, but it's even more common in elementary school (where many teachers are truly scared of teaching math, and some "math phobia" can definitely get imparted to the kids).

That's the worry, but I can't point to examples of it with my kids, the ES teachers were usually good with the concepts they were presenting. I did see faulty materials, and teachers who'd written their own problems that were poorly worded. Modeling math thinking requires concise language, and everyday English can be ambiguous. E.g., the statement "John shares a 20-inch licorice rope with each of five friends." Is this heading for a division problem or a multiplication problem? It's not clear if there's one rope or five. My DC definitely saw statements like this in ES, and even if the confusion was pointed out, the teacher tended to only hear the sentence as originally intended. Hopefully the editing in the new curriculum is better. If you can't get past issues like this, it's pretty hard to present proofs in ES.

I agree with this. 2.0 was particularly bad because it was home grown with zero quality control. At least an openly available curriculum would have some level of proof reading and editing.

A deeper problem with education in the US is that it does not follow child development guidelines and embrace more self guided learning. For some reason the US pushes reading earlier to no benefit and holds kids back on basic math concepts. Montessori kindergartens will have kids doing multiplication and division because developmentally they can easily grasp the concepts of grouping and separating sets. This is a great time to introduce those conceptual skills. In elementary school using games to ensure fluency and ensuring kids know their math facts is still important. You can't do more complicated math later on if you need to draw a picture or write a paragraph to do simple addition, subtraction, multiplication and division. The same is true of foreign languages. Students are far more successful acquiring a foreign language in preschool and early elementary than middle school which is the worst time to introduce this subject.

Lack of rigor is another problem especially in MCPS. There is huge pressure to create data that every students has met the standard and is moving forward appropriately when many are not as a result of not coming into the class with the needed skills, a bad curriculum or bad instruction. It doesn't really matter as they are being pushed forward without grasping math as MCPS continues to lower the standards. This doesn't help the students that can perform either. Their parents feel proud that their kid is getting an A in a class with an impressive label but if you place that same kid in a real Algebra or Geometry class they will get a rude awakening.

Agreed. Another observation that seems more true to me now than years back, is that kids seem less interested/engaged in learning for learning sake. I often see even the advanced kids only wanting to learn something to get that grade, or pass but lacking genuine interest. I suspect technology (particularly touch screens) have played a role in this, not only because they're spending more time on them at home from a very young age, but also because schools are now using them at an alarmingly frequent rate. It's rare to find kids who can truly concentrate without distraction for a longer period of time. If they cannot focus well, they will not be able to solve more difficult problems (the ones requiring thought and some amount of creativity to crack).

The learning process in our schools has also changed over the years. The sheer teacher time spent on testing is terrible and really reduces the meaning of teaching. In particular I think this is really harmful in the elementary school years since that's the time when kids are still very curious and will actually ask many questions, as to how things work, why they work like that, what if something else happens, etc. So I think it's harder to teach math effectively in elementary school, which makes it even more critical that teachers at that level are experienced and be able to logically explain how/why things work the way they do, as well as keep a kid's interest and curiosity alive. If a kid has not been inspired, and has also not been able to understand the basics to the point where they can somewhat explain how/why they work, they will likely get lost in middle school and see mathematics as a meaningless, repetitive set of calculations to be memorized which is really the worst outcome to have.
