They are NOT "required to have an iPhone"
It's a browser-based application.
When taking the SAT you can take it on a computer or on paper. Paper is being phased out. If the test is on a computer desmos runs on the same machine.
If a student is taking the test on paper the SCHOOL should provide a device that can run desmos or the student may use the approve graphing calculators the TI 84 is the most popular but there are others.
This guide I've made is meant to show just how powerful of a tool we have been handed.
Too many math teachers are thinking it's just like the TI calculators they have been using for years.
It's not. It is VERY different.
Most of the math teachers I talk to are shocked when they get to the "calculus" section and don't seem to grasp the implications of the things it does with fractions.

I don't know if desmos is "better" we are no longer buying graphing calculators for students. I have been trying to get the faculty to pay more attention to this issue.
Getting my hands on a calculator is what *MADE* me a math person. I think it's incredibly important.
Since students will have this software during the test they need to use it regularly as they learn. I'm also annoyed that few faculty seem to understand this.
They are not "required to have iphones"
The school should provide a device that can run the software. This could be a laptop or ipad.
For the test it needs to be the "locked down" version (no saved programs) but any device that can run the SAT test can also run desmos.
But it's a little messy.
Desmos makes noise now???
I had fun making sounds in desmos to go with this: https://www.desmos.com/calculator/qezi3o36sc?ref=fractalkitty.com #desmos

Why are people looking for alternatives to desmos? Did something go down?
#desmos is out of control. Here is my guide to all of the features I've found so far. You can make logic gates in there. You can do lists and iterate things:

They've added summation and it's a little strange sometimes how it works. This threw me. You set i to be a list and it give you three answers. It won't evaluate it if you don't set an upper bound.
I'm excited but also a little horrified that this is the new SAT calculator. It's just so feature-rich.
This seems reasonable, but would you recommend such a course of action to your less tech savvy older relatives?
My mom has a natural and good tech instinct to click "no" when her computer asks her to update. However, she's had so many viruses and the easiest way to clear them out is if she just keeps the windows OS updated.
She uses the computer for the web and as a word-processor. I'm annoyed such basic computing is so dangerous and complex.
If a company can make automatic software updates what additional responsibilities should that imply?
Could legislation that holds companies to a higher standard in this area make these updates less frequent and extreme?
It's wild that some of the people most likely to be seeking independence (owners of power walls) have been subjected to this treatment. I hope that they will be very nasty to TESLA about this, go full Karen. I will cheer you on.
I'm thinking about how "security" (virus and hacking protection) is often raised as a good reason to subscribe to automatic updates. Indeed, I allow my iPhone to update itself mostly because I think it's more secure.
But I have never felt comfortable with the way that software just changes whenever it wants.
The interfaces change, the functionality changes. We are promised it's for safety and "improvements" ...
But IDK what if you shipped software that was... complete?
"If they can be shut off with an over the air command we need to be able to trust the companies that make them."

Remote software updates, feature enabling/disabling, and the most extreme remote bricking raise several "consumer rights" issues that have not been adequately addressed. #tesla #solar #rightToRepair
This is a lot more silly than Wilson.
I'm going to use "rotifer toes" like other people use "twinkle toes"
As in "Listen, rotifer toes, this song and dance may fly up in Albany but we don't do that around here."

I'm kind of sad about that. I was a supporter for years.
You ever put some pond or puddle or moss water under a microscope just to check out what they are doing in there?
Well this is where you will see a rotifer. That's a good diagram. They are a bit like tiny water filters. They cycle water through their mouth and eat little bits and whatnots in the pond water.
Just part of the explosion of microscopic life.
Here is a lovely video about them:
I am horrified at the suggestion.
But you can be the food tester.
some were probably poisonous.
Consider the qualitative difference between watching a rotifer and watching an insect.
The rotifer is alive, it reacts. But it's like a little machine in the way that people THINK insects are like machines.
We need to bring them all back and find out.
Thinking about the early arthropods in the Cambrian seas. We know that they had a nervous system and brains from fossil evidence.
Many modern arthropods have more complex brains, and there isn't anything exactly like these early simple brains.
So, I wonder if you were to watch these creatures feeding and hunting would it be different from watching modern arthropods?
I think it might.
Could they hide? Did they get frustrated?
