(1) Another vote for Sphero. I bought Sprk+. I like seeing the innards and doing the simple blocky programming to make it move around the floor. {Hey you can even look at the C code behind the blocks.) It needs a mobile phone with Bluetooth

I love GeoGebra, https://www.geogebra.org/ . What a (free) resource to explore Math for oneself!

Use a tool like Symbolab. It shows you the steps for different methods. Very useful. Further, we should all remember to draw a graph as our first step. Symbolab, Desmos and Geogebra (my favourite) are all fantastic graphing software. Also,

I look at this way: early education focuses on learning to read and write and do arithmetic. The basic purpose is to give you tools whereby they can continue to educate yourself throughout your life. So basically, our early education aims t

I think I have read various aspects of this event. I would feel enlightened, if someone with more knowledge could provide more details to flesh out my (false?) memories. Different aspects I have read are (1) The programmer (a woman) set up

As a Math/Science teacher who has to make decisions every day about who and what to teach, I agree that "with a broad education we are fishing for advantages in the future". I see a similarity with playing sport. When we are

I was recently at an applied maths seminar. The speaker had been working on the main "over the horizon" radar in Australia for over 40 years. It was amazing to me that he could map ocean currents with radar!

I mention Geogebra, https://www.geogebra.org/ , because I believe more people interested in exploring mathematics should be using it. Me, I cannot get enough of it.

Word was fine for my PhD. My supervisor from those times - now 80 and still collaborating with scientists from around the world - has written hundreds of papers with it. I think I can speak for him when I say that over the last 30 years he

I prefer chess to Tetris. I like a clear goal, something achievable in a short time span. I like something where I have to think. I don't like shooter games (or Tetris): I mean, what's the point? Has chess improved my thinking ski

I use Baidu as my replacement for DropBox when I am in China. It works fine. One of my students set it up for me.

Nice video. I create similar diagrams with Geogebra, https://www.geogebra.org/ . What I like about Geogebra is (1) it's free and (2) I can build interactive diagrams without having to do any computer coding. I encourage

I am sorry. I have to let you connect the dots. I have a university job in China and I don't want to be kicked out of the country. Just follow the money.

I think you miss my point. As I see it, the Chinese government are basically blocking Google as a business decision. Take a look at Baidu. You will be amazed at the number of services they offer. On the roads in China you see a lot of Audis

I spend about 6 months of the year in China. Yes, I am forced, as you say, to use the Chinese versions of everything, but, to be honest, it doesn't worry me. I use Baidu to put my teaching notes online for my students - it is as good a

To me, Kino is a portrayal of the emotionally inert, of those who will not risk. The longer I live, the more of these persona I recognise (myself included). Come on, look about you, the computer profession is replete with this personality t
