There's a reason physicists tend to do well wherever they go.

@jamieamartin1 i understand why teachers/schools do this for now, but i think it's throwing the baby out with the bathwater long term. there is actually some good educational software on the market and more is coming! and we can do away with homework and get more people doing the work honestly

@sutherlandphys You just have no devices in class then no one can use AI in class either At primary - homework is overrated At secondary - old enough to take responsibility to learn if warned AI damages learning if used the wrong way.

I've said it before and I'll say it again. Professors need to wake up to reality. Stop with the assignments. Stop with the lectures. Have your students work through efficient, effective software during class, so you can supervise and ensure no cheating. Then, proctored exam.
Daisy Christodoulou@daisychristo

Everybody knows that everybody is cheating. Universities have so many people with the words "strategy" and "AI" in their titles yet on this issue, they can't seem to think through what is going to happen beyond the end of next week.

"Canada’s story gets even more depressing when only young people under 25 are counted. The country then falls to 71st, another new low. Young people were once, on average, the happiest Canadian cohort; now they’re the most miserable. And when compared to 136 countries, that 10-year drop in life satisfaction is one of the largest in the world, placing Canada just four slots from the bottom." On nearly every metric -- economic growth, prosperity, and happiness -- Canada is failing. We need to start doing things dramatically differently to change our trajectory. Incrementalism won't cut it.
The Globe and Mail@globeandmail

In the country’s worst-ever showing in the 14 years that the report has been published, Canada ranked 25th out of 147 countries in the life-satisfaction standings. theglobeandmail.com/life/article-c…

"Physics intuition" isn't something you're born with. You read enough physics, you do enough physics, your intuition grows.

@sutherlandphys Genuinely took me a second to get this one because any of those could be elements in a vector space. But I think you meant which are 2D vectors. Curious how you would change the question to prevent wrong-ruling

the "wrong-rule" audit is a great way to test your education app. For example, in this question, if we're asking them to select all the vectors, a student could figure out this question by applying the "wrong-rule"

That is, they are not optional. They are a way to force the student to slow down (but ideally only by a minimum amount) to take in the information, without immediately just skipping to the problems.

All these manim animations are supported by some text in the actual lesson. But we are purposely designing the examples and explanations such that it should be impossible to answer the questions without having studied the manimanimation.

PhysicsGraph is being upgraded with manim animations in many of the lessons to help reduce cognitive overload. There's a lot to making these actually achieve the desired aim. Take a look at the following video:

We are constantly looking for ways to upgrade the material in our platform. We're adding new question types to our entire course because those are especially important in the sciences. And as we do, we are applying things like the wrong-rule audit to make sure it's top quality

the wrong-rule being: there's text after the units. Instead of genuinely understanding the difference between a scalar and a vector, the student has identified another rule (that does not always work) to get the question right. So you must re-design your question
