Update regarding username changes on the forum
Hi everyone! We quite often get questions about how you can change your username on the forum, and what the policy for username changes is. With this post, we want to clarify the requirements for changing your username, and also announce a change to the rule: we now allow new users to request name changes without needing to wait one full year for the first name change!
So, the official rules for forum username changing are:
You may change your forum username at any time, as long as you haven’t changed your username in a year.
The change may be requested in the Leaders Q and A Topic and will be approved as long as you meet these requirements.
Keep in mind that usernames can not contain special characters and needs to be at least 3 characters long. They also need to be unique.
Quick update – we’ve updated the guidelines to make it easier to read. You’ll also be able to use the table of contents to find different parts of the post. If you have any questions about them, please feel free to ask here or on the Leaders Q and A Topic
I think in this case, it means more that everyone is capable of learning and understanding calculus just as much as you are, rather than everyone else has the exact same knowledge and experiences as each other.
(I know this is a long time ago but just saw it and had a reply)
Actually it also turns out that if you’ve ever modelled acceleration/gravity in Hopscotch, you’ve been using calculus!
This is from a paper on Squeak Etoys, which Scratch was inspired from (and then Hopscotch was inspired by Scratch)
This subject has been extensively studied with college students in US: 70% (including science majors) fail to understand this Galilean model of gravity near the surface of the Earth. The projects developed in Squeak use a different and simpler kind of incremental mathematics that allows very young children to understand some of the key ideas in calculus. We have found that more than 90% of 5th graders not only understand “Galilean gravity” but are able to derive the mathematical “formulas” (actually 2nd order differential equations) using this alternative mathematics, and author a simulation that matches up very well with the experimental data.
Yeah I guess it was a short addition in reply to my previous post. But I can’t quote my previous post in full, otherwise the quote would be removed by system anyway.
The quote from guidelines was “assume that others are just as smart as you are.” There was a point about calculus, but people are capable of understanding calculus.
