THREAD. For many it is the near the start of the fall semester. Here I will share my teaching and learning posts. Some of these are for faculty and some are for students.
2/ I'll start with posts that just deal with students. My first recommendation - ditch that scientific calculator. It's overpriced and not nearly as good as python wired.com/story/ditch-th…
3/ Three things to learn for physics lab: unit conversion, graphing, and looking past the instructions wired.com/2017/01/wanna-…
4/ In physics class, don't be an equation hunter. If you don't know where that equation came from, don't use it. wired.com/2011/06/dont-e…
5/ Dr. Strange is correct - learning takes years of practice. Don't be fooled into thinking there is some magic shortcut to understanding. wired.com/2016/11/doctor…
6/ It's ok to be bored - it can lead to some really cool things (but technology makes it difficult sometimes) wired.com/2016/06/its-ok…
7/ Error - for some reason, twitter stopped at post number 6. I will continue this thread manually. I guess I didn't even need to say this.
8/ Scientific calculators kinda suck. I recommend using python instead @GlowScript_Code @trinketapp wired.com/story/ditch-th…
9/ Please stop saying "I'm just not a math person" - this is a bad thing to say wired.com/2015/05/im-jus…
10/ Advice for students in physics wired.com/2015/03/advice… wired.com/2014/10/just-d… wired.com/2014/07/what-d… wired.com/2013/08/welcom…
11/ Yes, all of the physics solutions are somewhere online - but that doesn't mean you should use them wired.com/2013/09/yes-st…
12/ Learning physics is difficult - there is no shortcut to understanding wired.com/2015/08/learni…
13/ Here is my answer to the student question "Why don't you just tell us the answer?" - Confusion is the sweat of learning wired.com/2013/10/tellin…
For some reason, my thread was borked. Here is the rest

MEGA THREAD. Happy #PiDay to everyone.

Let's start with the simplest calculation of Pi - the ratio of circumference to diameter for round objects. wired.com/2014/03/calcul…
2/ If you want to do this calculation of Pi, just find a bunch of circular objects of different size. Use a string to wrap around and measure the circumference and then measure the diameter. Plot C vs. d - the slope is PI.
3/ But wait! #PiDay is only Pi in the USA where we use date format of month/day/year.

For everyone else, today is 14/3/2019 - which is NOT Pi. I suggest the other Pi day is July 22 (22/7/2019) since 22/7 is a great fractional representation of Pi. wired.com/2011/03/what-i…

THREAD. Need some #physics ideas to go along with your holiday presents? I have you covered.

Here is my list of some cool physics experiments I have done with toys and stuff.
2/ How fast are #Nerf darts? Video analysis included.
wired.com/2011/06/how-fa…
3/ What about the speed of the #Nerf vortex disks? wired.com/2012/01/the-fl…

THREAD - How about a bunch of blog posts on #Space and #Astronomy? Yes, I have more than you can imagine - especially since these are really just #physics topics. Hold on - because this is going to be a bit large.
2/ Here is an answer to my fav astronomy question EVER - "What would the phases of the moon look like if the moon was a cube?" wired.com/2015/09/moon-c…
3/ The great thing about the cube moon question is that it really tests if students understand phases of the moon rather than just recalling factual stuff. Here is my python model of a cube and spherical moon

Dear parents , when you send your kids ABROAD to study , please check up on them and find out EXACTLY what they are doing , who they are relating with , demand to see transcripts , fee receipts e.t.c and be in constant contact with the institution / teachers . Here is why #Thread
Today , a mother to one of my Ugandan friends who studies around here called me . She was in so much pain , she cried on the phone for hours , she told me she hasn't eaten for days because she has not been in contact with her son.
Her son came here to do Political Science 3 years ago and is supposed to graduate this month . She almost fainted when I revealed to her that her son hasn't been seen anywhere near class for the last 2 years . He ONLY did 1st year of campus . She cried so bitterly , she wept .

Read the midterm evaluations for my GWS 101 large lecture course. A little over 1/3 of the students filled out the evaluation online. Average rating of 4.5 out of 5. Vast majority of the comments positive. Best one: “Basically this course makes you a better human.” 🙃
I’ve been struggling with the fact that I put SO MUCH TIME into this class but I am very disconnected from the students & their learning experience since I only lecture while TAs lead discussions & grade. Sometimes it feels like shouting into the abyss & hoping someone heard.
These evals help remind me students are indeed learning & benefitting from the class, even though I don’t really get to see it. A nice gift as we push through the last five weeks of the hardest/busiest semester I’ve had in years.

This discovery changed the way I see business growth in Africa... "It's possible for people and companies to pay you to build your business."

If you understand this, BUSINESS CAPITAL will never be the reason you don't start your business!

#thread
For this to happen, you need to build an Asset. An asset here refers to anything that makes money for you.

The major challenge you'd face when attempting to do this is that your new business likely doesn't have an Asset.
A way to solve this is to discover an Asset that is complimentary to your business and can be built quickly.

The asset makes you money as well as it helps you build your business.

I want to tell you a story, one that APC supporters and sponsors doesn’t want you to remember or hear about.
This thread is for APC online and offline supporters, bots, and tyranny defenders.
It’s the story of a young man; Bukhari Bello Jega (Bless his soul) #Thread
Like many of you today Bukhari was a strong Buhari supporter, a critic of the GEJ admin; we read his tweets, Buharists RT’ed, like you see happening now.
He wanted change, and believed the Buhari “saint hard-man” posturing will bring the change.
We warned, just like we do now.
He encouraged Buhari even after swearing in, and promoted the little he did.
BTW, Buhari ordered selling of two jets, but none has been sold till date. So he was misled too.

Many things might spring to mind when someone says the word assessment, so this thread aims to clarify that our Assessment Lead Programme is nothing to do with data drops or tracking systems but everything to do with using the craft of assessment to support teaching & learning
When we talk about assessment, we’re referring to a planned, purposeful process that produces valuable information that leads to better decisions about #teaching & #learning
By supporting you to make your assessment practice & approach more effective & efficient, you can do more with less for a more manageable & meaningful use of #assessment

I recently talked with graduate students in a seminar on #teaching practices in #HigherEducation about how to design and teach a course when you are not an expert on all of the content--which is really what most teaching is. Here are the main takeaways for those interested. 1/
In my experience, there are four main mistakes that novices often make when designing and teaching a course for the first time.

First, they approach the task by venturing off on their own into the wilderness of literature on all of the topics they don't know well. 2/
In other words, they prepare for course design as if it is a qualifying exam, attempting to become experts on all of the topics that the course will/should/must cover. 3/
