math education learning teaching mathematics standards Common-Core

  • “Make sense of problems and persevere in solving them. Mathematically proficient students start by explaining to themselves the meaning of a problem and looking for entry points to its solution.”
  • “Reason abstractly and quantitatively. Mathematically proficient students make sense of quantities and their relationships in problem situations.”
  • “Use appropriate tools strategically. Mathematically proficient students consider the available tools when solving a mathematical problem.”

  • “Model with mathematics. Mathematically proficient students can apply the mathematics they know to solve problems arising in everyday life, society, and the workplace.”
  • “Attend to precision. Mathematically proficient students try to communicate precisely to others. They try to use clear definitions in discussion with others and in their own reasoning.”
  • “Look for and make use of structure. Mathematically proficient students look closely to discern a pattern or structure,” and “Look for and express regularity in repeated reasoning. Mathematically proficient students notice if calculations are repeated, and look both for general methods and shortcuts.”
  • Missing entirely from the practice standards is a discussion of how to pose problems, and, more generally, how to ask powerful questions. This is a telling oversight. Unlike in school, real problems are not served up on a platter, fully formed. The standards-writers overlooked the most basic fact of people with genuine math expertise: They find problems!
  • Is it too late to change this? I hope not. Solving our problem of poor mathematics education depends upon it.

    Interesting opinion piece about how the new standards in math miss the mark.

12 Ways To Be More Search Savvy | MindShift - 0 views

Internet web search google research

  • there are ways to be even more efficient, more search-savvy. And it’s our responsibility to teach kids how to find and research information, how to judge its veracity, and when it’s time to ask for a grownup’s help.
  • CONFIRM CONTENT. It’s common to find the same phrases and sentences on different sites all over the Web because people duplicate content all the time. To determine the original source of the content, you can look at the date it was written, but that’s also not entirely accurate. When authors edit an article, that changes the posting date. So even if it was originally written in 2005, the date will say 2011 if it was edited last week. Again, here’s when you put on your journalist hat. Trustworthy websites typically have an “errata column” or something like it where mistakes or corrections are posted
  • KEEP IT SIMPLE. Use search terms the way you’d like to see them on a Web site.

  • DEFINE OPERATOR. This has to be one of the best items of Google’s offerings. To learn the definition of a word, just type “Define,” then the word.
  • ONE MORE SEARCH. It’s one thing to do a quick search for Lady Gaga’s birthday. But for more important questions that have a direct implication on your life, do one more search. Go deeper and find a second corroborating source, just like a journalist would.
  • FIND THE SOURCE. Russell knows first-hand that Web sites can sometimes publish false information. Though we all know how to find contact information for an organization, confirm the phone number, look for the author’s names and trustworthy hallmarks like logos,
  • CONTROL F. A deceptively simple tool, the Control F function (or Command F on Macs) allows you to immediately find the word you’re looking for on a page. After you’ve typed in your search, you can jump directly to the word or phrase in the search list.
  • LINK OPERATOR. The way Google ranks sites can be confusing. Sometimes even when a site has negative comments or reviews, it still rises to the top of the search list simply because it’s been mentioned the most. When you want to know what other sites are saying about the site you’re searching, type in “Link: www.yourwebsitename.com” and you’ll see all the posts that mention that site.
  • DON’T USE THE + SIGN. It might have negative side effects, Russell says. Adding the + sign will force the search engine to look for only that phrase and may tweak the search in a way you didn’t intend. That said, it’s a useful tool for looking up foreign words or very low-frequency words.
  • PAY ATTENTION TO “GOOGLE INSTANT.” In most cases, Google’s instant search function, which is fairly new, will accurately predict what you’re searching for and offer suggestions.
  • SWITCH ON SAFETY MODE. If you’ve got kids in the house, Russell suggests enabling safe search. In your Search Settings, scroll down to SafeSearch Filtering (or use Control F to find it quickly!) and choose what level filter you want to use. You can tailor it to every computer in the house. Google offers all kinds of safe search tips and functions on Google’s Family Safety Center.
  • FUNCTIONS GALORE. You can use Google to do calculations (just type in “Square root of 99″ or “Convert 12 inches to mm”). You can search patents, images, videos, language translations. And even if you can’t remember a Google function, you can easily search it.
  • LEFT-HAND SIDE TOOLS. Most people don’t notice these exist, but when you search a topic, a list of useful, interesting tools come up. For example, when you type in War of 1812, on the left hand side, you’ll see “Images,” “Videos,” etc., but below that you’ll see things like “Timeline,” which maps out a time sequence of events around the War of 1812 and links to each of those events. There’s also a dictionary, related searches, and a slew of other helpful links.
