Knowing the multiplication tables is a good baseline, but it's also important to grasp "number theory" to be able to do shortcuts If you can't remember what's 8x3, you can still do 3x5 and 3x3 and add them together That comes out to 15 and 9 You know that 9 is made up of 5 and 4, and you also know that 5 and 5 instantly make 10 So you break down 15 + 9 into 15 + 5 + 4, which is the 20 + 4, which is 24 8x3 = 24

DingTalk is probably one of the few apps that gets bad reviews for being really good at doing its job. The productivity app from e-commerce giant Alibaba has long had a love-and-hate relationship with Chinese employees, with one observer calling it an “Orwellian” version of Slack. In recent weeks, it’s been review bombed by its newest users, after Alibaba adapted the app for the country’s gigantic online learning experiment. Most Chinese schools and companies have been operating virtually for weeks in the wake of the Lunar New Year holiday, after coronavirus cases surged in January and Beijing put many cities under a strict quarantine. DingTalk’s new features (link in Chinese) for schools include live-streamed classes for as many as 300 students, and online testing and grading features—more than 50 million students are now signed up to use it. Many of these students bombarded app stores with one-star reviews for DingTalk, complaining the app had ruined their extended holiday by allowing teachers to remotely monitor them. “I am really speechless, teachers require us to check in every day and gave us loads of homework,” said a user on Weibo (link in Chinese). DingTalk saw its rating bounce back (link in Chinese) slightly this month supported by a flurry of five-star ratings, with some saying the app would train students to be good future employees. “I can see which students have read my notices and ‘Ding’ those who haven’t easily using the app…,” said a Chinese teacher at a primary school in China. “I understand why managers like to use ‘Ding’ message—as employees we should reply to our bosses quickly anyway.” How is DingTalk different from Slack? Founded in 2014, the app, which is called “Ding Ding” in Chinese for the sound its messages make, is part of Alibaba’s efforts to compete with its rival Tencent, owner of messaging app WeChat, in the corporate space. While DingTalk has many of the same features as Slack, including group communications, voice and video calls, and file-sharing, DingTalk also includes a slew of monitoring features the US app doesn’t have.The Ding message function allows managers to ping specific employees—these messages feature a blue thumbtack logo. Ding messages can be sent to employees not only in the app, but also through automated phone calls and text messages. Then, managers get read/unread status updates, making it tricky for employees not to respond if they happen to glance at a message during time off, triggering a “read” receipt. A manager at a corporate user can send up to 10,000 “Ding” messages each day within the app. Meanwhile the app’s clock in/out function, one of its most-used features, has been described as a “digital punch card machine” by some. In the morning, it sends reminders to users about how many minutes they have left to get to work. It also keeps tabs on when employees arrive at work by logging what time they connect to the office Wifi, and when they disconnect, for example to go to lunch. While the feature also helps workers track and get paid for overtime, and is less hassle than scanning a phone code to clock in as some companies used to require, it also allows companies to measure lateness down to the minute, and whether a worker is doing what they said they’d be doing when they’re not at the office. DingTalk has said it doesn’t allow managers to track (link in Chinese) employees’ real-time locations automatically. However, when a user enables location services, the app will tell managers if an employee was at a location they said they’d be, such as at the doctor or at a client meeting. Apart from location-based clocking in, DingTalk also has a facial-recognition option that requires employees to smile when they scan their face to check in or out. How many people are using the app? DingTalk said it had 200 million individual registered users and over 10 million corporate clients as of September 2019. In comparison, Slack had 12 million daily active users as of last October. What are the major complaints about the app? Most of the complaints focus on how managers can use DingTalk to monitor and reach employees round-the-clock. “I really feel DingTalk is like hell, especially when I finally have some time off and want to have a good sleep but am awakened by ‘Ding’ messages,” said a user on Zhihu, a Chinese question-and-answer website. “DingTalk is a high-tech, modern day shackle used by management to treat employees as slaves,” said another. For many Chinese students, the app has stripped them of the already very limited freedoms they had during this unexpected time out of school. Some complained that the clock in/out function means they can’t sleep late, and have to follow the school’s schedule at home. “Thanks to the app, the piles of homework finally came back to me again and I can see the loving faces of teachers everyday! I love it so much, my beautiful DingTalk!” wrote a student (link in Chinese) sarcastically on the app’s IOS page. Alibaba did not immediately reply to a request for comment on the negative reviews—but DingTalk took note of the complaints and put out an apology video (link in Chinese) filled with memes and jokes, asking students to treat it more kindly. “I know you young people don’t want to have such a ‘productive’ holiday… but please stop giving me one stars,” said the video’s narrator.

china probably actually pays math teachers and therefore still has math teachers, probably even good ones. the different between having someone who can teach math and the typical person that sticks around beyond the short-year burnout timer in american schools is insane. some people have and maintain some fun with math early but I think a lot of people who end up going "im gonna do math for a while" have one or two teachers who they click with and actually do learn well from. I think math has a lot of rote memorization required (all learning does and you can boil down a lot of other terms to rote memorization but it's not really useful to do) but it does have some things beyond that that you can firmly grasp in calculus. before calculus too, but that's actually probably harder to get a sense for. doing the typical year after of differential equations/linear algebra or whatever else beyond calculus is well in building intuition land. it's not the same kind of 'actual' mathematical intuition people who go through a proof-based curriculum will develop but it's still valuable. definitely does not require knowing what 5x5 is by rote though. you can genuinely just skip times tables. you'll pick them up as you go. or not. doesn't matter a single bit. anyway the US' treatment of its teaching labor pool has always sucked and has gotten worse. probably not true of china. that "force students to do their homework" comment is a joke I think but that is not a thing that actually works unless your goal is to just browbeat them into rote memorization and testing accordingly.

this allusion meant posted:what're the mathlete strats for these? my method for three to four digit multiplication is to factor into easier chunks and rearrange until i see easy ones, so 132 becomes 12x11 and 217 becomes 7(30+1), at which point i stumble a bit working out how i proceed but it goes 31x7x12x11=31x3x4x77=31x2x2(210+21)=31x2x2x231=(30+1)x2x462=(30+1)924=(27000+600+120)+924=28644. but after writing that out i could also imagine (140-8)(220-3) working out faster and with less/easier searching through factorization space? are there good rules of thumb for telling ahead of time what's faster or do you pick a favorite and drill it or develop an instinct for it or what ok but I was just saying that the 'easy' patterns are ones recalled from rote memorization not ones that are fundamentally easy. multiplying by 100 means adding two zeros but multiplying by another 3 digit number I might have to break it into recognizable chunks, like you just recognized 7x11=77 because a single digit times a series of ones just repeats the single digit as many times as the ones were repeated. it's a pattern you tell a kid over and over and then we look for it, but you wound't program a computer to do math that way, cause computers actually do math, not just recall rote facts and slam them together. and I'm thinking more the people who say 'rote memorizations sucks' don't realize they do their math from this rote memorization too

Antonymous posted:people think their math skill is something they 'developed an intuition for' but all those fun math paradoxes / tricky problems basically teach you that you had a shortcut that worked in many examples but is not actually math knowledge. if that makes sense. The best math learning I ever did was when I was tutoring it because now knowing poo poo isn’t enough, you also have to figure out how to explain it, preferably in multiple ways, and that quickly leads to having to understand why something is true rather than just that it is true.

so one of our senators had the bright idea yesterday to propose banning Korean movies and shows from Philippine airwaves, supposedly to get people to support local media instead I'm a lot less interested in that, but it did make me think: did South Korea engage in a kind of protectionism in its efforts to develop its K-Pop industry?

Petey posted:well, if you look at india proper, the focus is so much on the JEE that the olympiads don't play as much of a role, and i expect that filters out into the broader diaspora too. team usa has certainly had some strong indian-americans on it, but iirc they've mostly been from school districts where the cultural norm for high-achieving stem students was to do olympiad stuff (as opposed to robotics or science research or whatever). there's also not a strong pipeline of olympiads to medical school, whereas there is a strong pipeline of olympiads to engineering, and so the parent networks share different kinds of enrichment opportunities (you see much more indian-american representation at the top levels of the science research competitions that culturally feel more like medicine, for example). Thank you for the 2 great posts. Didnt know about the medical related competitions. I guess the medical prizes to the Indian amercians is basically what Guinness world records are for the Indians.

lol https://www.blackburn.senate.gov/2022/10/blackburn-colleagues-call-on-president-biden-to-oppose-huawei-aligned-semiconductor-plant quote:WASHINGTON, D.C. – U.S. Senator Marsha Blackburn (R-Tenn.), along with Senators Tom Cotton (R-Ark.), Bill Hagerty (R-Tenn.), Ted Cruz (R-Texas), and Marco Rubio (R-Fla.) sent a letter to President Biden demanding he act quickly to prevent Huawei from building the Pengxinwei IC Manufacturing Company (PXW) semiconductor plant. The opening of this plant would put the United States at a disadvantage in countering Huawei, advance Communist China’s Military-Civil Fusion campaign, put American semiconductor companies at a disadvantage, and pose a national security concern. Not only is this factory in China, it uses basically no US equipment. Please Biden, stop the Chinese from building this factory.
