| Jun 14, 2017 at 15:31 | comment | added | schremmer | @JessicaB For a few big numbers: (insidehighered.com/views/2017/05/01/…) Now mostly known as Developmental Math: (devmathrevival.net) but coming to you as Foundational Math: (ccp.edu/college-catalog/course-offerings/…) | |
| Jun 9, 2017 at 2:11 | comment | added | schremmer | @JessicaB See (duckduckgo.com/?q=Developmental+education&t=ffab&ia=web) and, more or less at random, [www2.ed.gov/PDFDocs/college-completion/…, (nade.net), (pearson.com/us/higher-education/why-choose-pearson/…), etc | |
| Jun 8, 2017 at 6:37 | comment | added | Jessica B | @schremmer I goggled 'developmental education'. I still don't know what you mean by it. I've found a page that collates all the other answers given... they clearly refer to completely different things. It seems that 'developmental education' is not a standardised term. | |

| Jun 6, 2017 at 21:10 | comment | added | quid | @pjs36 there is so little traffic on meta, really no need to hesitate to post. Anyway I'll look into it. Thanks for the pointer. | |
| Jun 6, 2017 at 14:41 | comment | added | pjs36 | @quid I know this is more of a Meta topic, but I'm not sure a Meta thread is warranted: MESE also has a remedial-courses tag, and I'm not sure what the overlap is here. | |

| Jun 5, 2017 at 13:06 | comment | added | schremmer | @quid I did not know that, at least here, "typing something into the tag-field that is not yet a tag will create a tag." Thanks for the edit. | |
| Jun 5, 2017 at 13:03 | comment | added | schremmer | @TommiBrander As I said, please just Google "Developmental Education". | |

| Jun 4, 2017 at 16:45 | comment | added | Tommi | @schremmer Could you suggest a tag wiki or tag summary for the development mathematics tag? I had not heard the term before, and the meaning is not at all to obvious from the title of the tag alone. | |
| Jun 4, 2017 at 12:26 | comment | added | quid | As a matter of fact, you could have created the tag. (Having 150 points suffices for this.) In fact, I believe you did create the tag with this question. (Note that it takes no particular action to create a tag; typing something into the tag-field that is not yet a tag will create a tag.) I renamed it a bit in the hope the longer name will be more easily understood. | |

| Jun 4, 2017 at 4:52 | comment | added | G Tony Jacobs | You asked whether I was joking about defining numbers as locations on a number line. Nobody else took it as a joke; try taking it seriously. Your students can understand that. Give them a little more credit. | |
| Jun 4, 2017 at 3:38 | comment | added | schremmer | @TommiBrander 1. Being new here, I obviously could not have created the tag. 2. Please Google "Developmental Mathematics" 3. The developmental population in U.S. colleges, particularly community colleges, is huge. 4. I never said GTonyJacobs was "talking nonsense". | |

| Jun 2, 2017 at 23:42 | comment | added | G Tony Jacobs | @TommiBrander , can I get a reality check here? Am I talking nonsense? | |
| Jun 2, 2017 at 23:40 | comment | added | G Tony Jacobs | Um... no, I'm not. What is wrong with that definition of "number"? It's comprehensible at a very early level, and it's sufficiently accurate to do a lot of mathematics. | |
| Jun 2, 2017 at 23:38 | comment | added | schremmer | Surely you must be joking. | |
| Jun 2, 2017 at 23:29 | comment | added | G Tony Jacobs | If the students don't have a precise idea of what a number is, that should be addressed. "A number is a location on the number line" is as precise as they need for a good long while. | |
| Jun 2, 2017 at 23:28 | comment | added | G Tony Jacobs | See my edits below. It certainly is the square root of some number, and by doing a little bit of algebra, you can see which one. | |
| Jun 2, 2017 at 23:24 | comment | added | schremmer | Certainly NOT. First, most people ( including math teachers) do not have a precise idea of what a number is. They mostly have mental images. Second, I quoted the question as closely as I could but the leading assertions would seem to indicate that what the question really is is "So why isn't √2 + √3 the √ of some number?" | |
| Jun 2, 2017 at 23:01 | comment | added | G Tony Jacobs | When they ask you why it isn't a number, is your first answer that it is, in fact, a number? | |
| Jun 2, 2017 at 23:00 | comment | added | schremmer | I am sorry. The tag is "developmental" but, in fact, the question has been asked many, many times, more or less in that form, by students up to and including Sophomores. (But then I teach in a CC.) However, occasionally, "professionals" have also asked me the question. | |
