# The most interesting parts of “Respect: The Life of Aretha Franklin”

There is an endless number of great soul singers who marched through the Franklin household. Smokey Robinson was a friend of Aretha’s brother, Cecil:

“Cecil and I were kids when we met,” he told me. “We grew up on the same love of music — not just gospel, but jazz. The first great voice that influenced me was Sarah Vaughan. I don’t think Cecil and I were ten when we started digging progressive jazz.”

Aretha’s father, C.L. Franklin, was a famous preacher at the New Bethel Baptist Church at 4210 Hastings Street, in Detroit. His most famous sermon was “As The Eagle Stirreth,” a bestselling sermon recording:

“Hastings Street is ground zero for the Aretha Franklin story. Her father’s New Bethel Baptist Chruch was at 4210 Hastings, steps from the heart of the black entertainment district. It was the point where Saturday night merged into Sunday morning and sin met salvation at the crossroads of African American musical culture … Was it the grinding grooves of the club that got into the church, or was it the sensuous beat of the church that got into the club? Did C.L. Franklin get his blues cry from Muddy Waters the same way Bobby Bland borrowed his blues cry from C.L.?”

When I first visited Detroit from Chicago,” said Buddy Guy, “it was later in the fifties. I had to see two people. The first was Reverend C.L. Franklin, ’cause B.B. had told me he could preach better than Howlin’ Wolf could sing. B. was right. … Gospel music made folks happy. Blues made folks lose their blues. I didn’t see that much difference between the two, even if preachers did claim it was the difference between Jesus and the devil. B.B. King loved C.L. Franklin because he didn’t say that. He didn’t pit one against the other. He said all good music came from God.”

Reverend James Cleveland was one of my favorite coming into this book. His piano playing is so heavy. The author asks him “which came first — the spirituals or the blues?”

“Aretha’s father would laugh at that question,” said Reverand Cleveland, “because he knew there was no answer. It’s a riddle that can’t be solved. You could say that the spirituals came first, but if you broke it down further you could also say that the field shouts came before the spirituals. How do we know whether someone out there was picking cotton didn’t first start moaning about how tired he was, or about how much he wanted a woman? Then maybe a God-fearing woman heard that song and switched it up to where she was praying for God to save her. The fleshy needs and the godly needs are very close. We’re likely to use music to call out both those needs because they’re both so basic. Which comes first? You tell me.

Aretha’s first husband took control of her career and beat her violently. Aretha’s peers call him a “gentleman pimp.”

“You can’t understand the music culture of Detroit in the early sixties,” said R&B singer Bettye LaVette, who emerged from that culture, “without understanding the role of the pimp. Pimps and producers were often the same people. The sensibility was the same — get women working for you; get women to make you money. We demonize pimps now, but back then they were looked up to by men and sought out by women. They had power. They knew how to survive the ghetto and go beyond the ghetto. Some of my best men friends were pimps. Some of the women I admired most were working for them — classy, sophisticated, beautifully dressed women. I didn’t have what it took to be a high-class prostitute of the kind that the best pimps like to parade, but as a singer, I was certainly pimped by certain producers — and glad to be.”

“Back then, women were powerless. If we wanted to get ahead in show business, we had to operate in the system. The greatest example of that system was probably Motown, where Berry Gordy’s first wife, Raynoma Singleton, claimed that Berry himself had pimped women. He wasn’t good with whores, but he was great with singers. The parallel is strong.”

Aretha got her first recording contract with Columbia, where she released a series of eclectic, well-reviewed albums that didn’t yield any hits. She showed an acute desire to record showtunes and various standards.

“Al Jolson had sung “Rock-a-Bye with a Dixie Melody” in blackface in the twenties. Later it was recorded by Sammy Davis Jr., Judy Garland and Jerry Lewis. Though an essential American song, it seemed a strange choice for Aretha, especially at the start of the civil rights movement. Cecil [her brother and longtime manager] explained to me C. L. Franklin’s love of Al Jolson and his reason for urging Aretha to include the tune.”

“My father told me how Jolson harbored great affection for black people,” said Cecil. “His entire blackface act was a way of paying tribute to our musical genius. Dad knew the history of American entertainment and had read how Jolson had hired black writers and helped bolster the career of Cab Calloway. We forget now, but back in the day, Al Jolson and black people had a mutual-admiration society.”

“In spite of Cecil’s spirited defense of Aretha’s inclusion of the song, it’s difficult for me to listen to her version without cringing. Although her vocal is enthusiastic, the strings feel anemic, the horn chart cheesy, and the rock-’em-sock’em finale forced and false.”

Aretha had difficulty reaching widespread fame while recording jazz and standards for Columbia.

“While working with Etta [James] on her book, I asked her why she thought her string-heavy jazzy standard turned into a smash while, in that same year, Aretha couldn’t hit with a bluesy standard like “That Lucky Old Sun”

“The answer’s easy,” said Etta. “Aretha sang the shit outta those standards — just as good if not better than me. But Columbia didn’t know how to reach black listeners, and my company, Chess, did. Leonard Chess had a genius for feeling out the black community. Jerry Wexler was the same. They were white Jews who would never use the word [n-word], but they us [] better than we knew ourselves. Columbia didn’t have no one like that. They had John Hammon, but he was like a college professor up there in the ivory tower. He wasn’t street like Chess or Wexler.”

Not really sure what this was about. Apparently Jerry Wexler was almost … killed?

“I’d just come back from a music-industry convention in Miami, where I was to accept an award on Aretha’s behalf,” Wexler remembered. “In Floriday, what I thought would be a pleasure turned into a nightmare. Gangster elements had taken over the industry’s black-power movement. During the banquet, King Curtis came up to me and said, ‘We’re getting you outta here. You’ve been marked,’ King escorted me out to safety. Later I was hung in effigy. Phil Walden, Otis’s white manager, received death threats. Marshall Sehorn, a white promo man, was pistol-whipped. It was some scary shit.”

By the way, King Curtis seems like a great guy. He’s certainly a great musician.

Apparently Aretha’s live performances were hit or miss. But there are some really special performances. Here she is with her childhood friend Smokey:

By the way, is there anything more devastating in popular culture than the list of soul and R&B singers who died far, far too young under tragic circumstances? Donny Hathaway, Sam Cooke, Sam Cooke’s brother, Marvin Gaye, Otis Redding, Billy Holliday, Nat King Cole. Aretha was personal friends with nearly all these people, childhood friends with half of them. Her mother died when she was a child.

Two of my favorite piano players, Richard Tee and Billy Preston, also died too young. Here are Aretha and Billy playing together:

I haven’t quoted at length any of the emotional drama from the book, which I found sad and also tedious. The short story is that Aretha was a difficult person, prone to depression and delusion. She was a teen mother twice over, and largely left her children back in Detroit while pursuing her career in New York City. She canceled gigs on whim, had extravagant tastes, and created relationships for the press out of whole cloth. She comes across as a brilliant artist who was committed to staying relevant and having hits, even into her sixties. Those around her frequently express regret that she didn’t age more gracefully as an artist — all except Ray Charles, who completely identifies with her desire to stay on the charts.

What I’ll remember from this book is the picture of Detroit as a place that was just overflowing with musical innovation in every direction. It was the epicenter of something amazing happening in popular music, and it all seemed to be connected to Aretha’s father’s church. Everyone seemed to know Aretha.

There was another passage that struck me, though I can’t find it now. There was a bit where someone mentioned that a lot of the folk and rock music on the radio featured more cryptic lyrics, whereas soul and R&B tended to have more straightforward story songs. Country is like that too, and so was early Rock and Roll. I don’t know what to make of that, but it’s interesting.

# Geometry Journal #3

Problem 1-14 from Challenging Problems in Geometry:

This took me a while to understand, but once I had a sketch it didn’t take me very long to use isosceles triangles to show that there were a bunch of congruent triangles in the diagram. I did this on paper, but thought it would be nice to put this into Geogebra.

The most satisfying diagram came when I started with a square, ala Challenge 1:

From attempting this problem and then studying the solution I didn’t feel as if I learned any new techniques. But this result is really awesome, and it’s one that I want to remember. It reminds me of midpoint quadrilaterals — the quadrilaterals formed by connecting the midpoints of a 4-gon. It’s pretty.

Ooh! Just looking at this now, it occurs to me that I should be asking “what is the ratio of areas between the original square and the trisector-square?”

I just tried to calculate it … I got $\frac{2 - \sqrt{3}}{3}$, or about 8%. Seems to check out.

After the last few problems took a lot of energy, it was nice to feel this one come a bit easily.

***

The next problem wasn’t an immense struggle either, mostly because I didn’t have paper around so I just skipped to the hint.

Like I said, I didn’t have paper and I wasn’t sure what to do, so I skipped to the hint.

It’s a nice hint:

These theorems say:

• If a line is perpendicular to another line m, it’s also perpendicular to any lines m is parallel to.
• Side splitter: connect two midpoints of a triangle and you get a line parallel to the other base

I very much enjoyed taking those hints and figuring out how to use them, even though it didn’t take too long.

The result isn’t so interesting to me, but I think there is a problem-solving takeaway:

Takeaway(s): If a diagram has a lot of midpoints, there’s also a lot of parallel lines.

If you’re trying to prove that an angle is 90 degrees, try to start with all the other 90 degree angles in the diagram. See if they lead to other right angles.

***

I’ve been reading a lot about self-explanation lately. This is a notion emerging from cognitive science research that suggests an important part of learning is explaining things for yourself — making inferences beyond what is explicitly there. This is often seen as crucial for learning from worked examples, i.e. solutions. This is something I am doing as part of this geometry project.

In one of his papers (let me know if you want the reference) Renkl distinguishes between different types of self-explanation. One that he thinks is particularly relevant for learning math is principled explanations. In other words, connecting specific examples to general principles. It makes sense that this would be useful — it means you can use this specific example to help with other problems!

The thing that I’m realizing while studying geometry is that without a teacher’s help, I’m basically guessing as to what the general principles are. I think my “takeaways” above could be useful for tackling other problems, but I don’t really know for sure. This is relatively new to me! I won’t know for sure until I find a chance to use the techniques in another problem.

I guess this is just another way that learning from a teacher is easier than learning on one’s own.

# Geometry Journal, #2

The problem:

My process:

I put a rectangle into Geogebra. It actually took me a few tries to really nail down what the problem was saying, but once I did I started dragging the points around. I noticed that the angle made by the two perpendiculars was constant also. Cool! After noodling around with the diagram I understand why:

I started drawing a lot of lines. This is another one of those diagrams that has a bajillion similar triangles. I was playing with this while my kids were going to sleep, so it was about 30 minutes of lazy drawing and redrawing. I found a lot of congruent triangles, some I was pretty sure would help me, but I couldn’t make them work. Here was my favorite congruent triangle pair:

After skipping to the solution of the previous problem (and seeing Benjamin Leis’ solution) I was feeling motivated to find a solution to this one before checking the solution.

I grew frustrated with the computer and (following my takeaway from the previous post, actually!) I took out some paper and started writing equations. I was thinking about how I would get an expression for EF + EG (the two perpendiculars) and I had the idea that you could do that using similar triangles.

I took the two triangles above and set them similar to each other. Awful quality I know, sorry:

Here is that picture, cleaned up a bit:

The point is that if those triangles are similar, then those perpendiculars are in ratio also. Some fiddling tells us that if that’s so, the sum of the perpendiculars is equal to:

$\frac{EF*l}{x}$

Is EF a function of x, so that the x’s cancel out? If so, we would be done. Call that yellow angle in the top right corner theta.

$\Large \sin{\theta} = \frac{EF}{x}$

$\Large x \dot \sin{\theta} = EF$

And that works. The sum of perpendiculars is equal to $l \dot \sin{\theta}$.

***

Here is the book’s solution:

Here’s the point:

It’s a nice solution. When I was looking for a constant I was trying to do something like this — slide a segment over using a rectangle. The problem was I couldn’t get the right structure when I was trying this, I always ended up stuck with a trapezoid.

The big strategy here is “when you’re looking to prove something is constant, you can try to construct the thing out of both pieces.” I did try that first, but ended up stumped so I moved to a different approach.

Otherwise, I’m not sure what else to take away from this solution. The move of using an isosceles triangle to prove both sides are congruent is sweet.

# Geometry Journal, #1

The problem:

I spent about 15 minutes noodling around. I tried adding different lines. I tried writing ratios, because there are so many similar triangles here. I had trouble using the digital annotation tools I was using, which made it harder to mark congruent angles. Eventually I started thinking about how I would get EF + DG as an expression at all, so I started thinking about making rectangles. Maybe their perimeter would somehow be useful?

I was feeling ready for a hint, so I turned to the back of the book for this hint:

“Draw CD, CE, and the altitude from C to AB; then prove triangles congruent.”

I quickly saw how this would be useful. I had already tried drawing these lines, but I hadn’t seen how it would be useful. Now I saw that if I could prove these triangles congruent, I would immediately have DE = EF + DG. I don’t know how I missed it earlier:

I didn’t have the angles yet. I was confident I would need to use the isosceles triangles that BD = BC and AE = AC created. Still, I was having trouble, and was feeling impatient. I decided to look at the solution.

The solution:

Commentary:

That’s pretty much what I was expecting, though it’s a bit annoying that I didn’t get it easily. Was I just lazy? I was definitely a bit lazy. But I think there’s something else here worth remembering, which is that when the angles are all bunched up like this it can be useful to write the actual equations using the angles out. I think it would have been easier to see the relationships that way, as I had a hard time seeing all the relationships in the image. (I struggled to annotate the diagram in a way that contained this info after reading the solution.)

A very brief note: I tried to use a tablet to draw on the image, which sped up the process in some ways. It also makes me more reluctant to write out equations in a way that would have been helpful here. I used Google Jamboard for this problem, but I’d like to find something better.

Takeaways: don’t forget to write equations for angles; maybe do that on paper or find a better way to do geometry on the tablet.

# We can’t agree on schools because they are compromise institutions

Coca Cola is a cola-producing, money-making enterprise. Hospitals are in the business of keeping people alive and healthy. Congress is in charge of making laws. Planned Parenthood supports reproductive health for women. Unions protect the interests of their members. And so on, and so on. All of this is relatively clear and straightforward.

Schools are different. Nobody can tell you exactly what it is that schools do.

(Update: my friend Chavi is a high-risk pregnancy doctor and author of a fantastic book that you should buy. She tells me, “You’ve got hospitals ALL WRONG. We are a TOTAL compromise. Social safety net, economically compromised model, plus restaurant and God knows what else. I like to point out that a really good hospital is also a really mediocre hotel.”)

Schools are in charge of teaching kids the things they need to get good jobs. That’s a matter of social justice. Or it’s about national security — you’ve got to keep up with the USSR Chinese.

Don’t forget about childcare, to support more people going into the workforce. That’s an important part of what schools do, their most basic function.

Actually — no! Schooling isn’t about jobs, national security or the economy. It’s about democracy. We need to create the next generation of informed citizens, prepared to vote and run for office and such. They need to know history, sure, but they also need to be schooled in democratic values. Kids need to learn that you can always improve by working hard. They also need to learn to respect their classmates, no matter if they come from a different place, worship differently, or have a different culture.

Really, though, school is about socialization. Kids need to be around other kids to be happy. They need to be part of a community where they get to make friends and find themselves. Schools give kids the chance to find themselves in passions like sports or music or art.

The point is that schools are all these things at the same time. Not everybody cares about all these things at the same time, but each purpose of schooling has its own cheering section in American society. We all care about schooling, but for different reasons.

David Labaree wrote a well-known essay describing this dynamic. In “Public Goods, Private Goods: The American Struggle Over Educational Goals” he lists three big categories for how Americans think about the purposes of schooling:

• social efficiency (think, jobs and economics)
• social mobility (think, meritocracy)
• democratic equality (think, values of democracy)

This is the fundamental fact about schools: they are compromise institutions. They simply do not have a main purpose. They aren’t in the business of helping everybody learn the most that they can. Schools aren’t organized around giving everybody the same opportunities. They aren’t built to give meaningful experiences to children. They do all these things, but in a compromised way. Because they are compromise institutions.

A lot of “innovative” schools produce their innovations by going all-in on one of these goals while caring less about the others. You can certainly organize a school that produces learning gains — as long as you spend less time worrying about whether kids get more choices and chances to collaborate. And you can definitely organize a school that is completely untracked and gives everyone the same learning opportunities, but you’re going to have to give up a bit on some students’ individual achievements. You can get a Success Academy for a while, but eventually gravity will drag it down into the weird, tangled matrix of compromise that most schools have to grapple with.

I’m not saying that schools are compromise institutions and that this is a bad thing. Schools are weird. Public schooling isn’t that old — it’s a complex project that meets a lot of different people’s needs. It has evolved to do a reasonably good job keeping a majority of people happy, but that has involved a bit of layering and duct tape. Ah ok, the nation needs this? We’ll start teaching Biology. We’ll offer college classes. We’ll have music. We’ll do anti-drug talks.

There is nothing natural about schooling. When push comes to shove, and we have to rethink schooling with limited resources, don’t be surprised that we can’t easily come to agreement. Imagine you ran a local drug store and suddenly had to cut your inventory in half. Do you stop selling food? Keep the first-aid supplies but ditch the mouthwash? Your store has a lot of random stuff in it, because your store is a catchall for a lot of random needs that people have. You aren’t a grocer; you sell a lot of unrelated stuff. That’s what schools are like.

Many teachers have argued that in the autumn of 2020 schools should be entirely remote. After all, hybrid learning is going to be a pedagogical disaster, probably worse than remote learning. (It’s just remote learning but more confusing.) Why not go remote? That makes a lot of sense, if all you think about is learning.

A lot of professionals have argued that school should go back full-time, especially for the youngest students. These parents need childcare! How is the economy (and everything else) supposed to function when people are suddenly at home with their children. This is absolutely true. That this is the job of schools is a totally legitimate view.

Really, though, everybody should go back. (Safely, of course.) Kids need to be in a social environment, not miserable and locked up at home staring at a screen. It’s not good for kids. It’s not about childcare, it’s about thriving in a meaningful environment. (This is the view my own school has taken, I believe, and all grades are currently expected back in September.)

My point is not about who is right. Honestly, I don’t know! The point is that to understand why there is so much disagreement you need to understand that it’s not that people don’t value the economy, childcare, the social lives of children or anything else. It’s that schools are weird. They exist in a strange space and occupy a weird set of roles. They aren’t simply institutions; they are settings where a variety of institutions and forces play tug-of-war and compete.

That means that if you want schools to come back (or to go hybrid, or to go fully remote) you have to make a really complicated case that satisfies a lot of different desires. We don’t agree on what is the most important for children. We don’t agree on what schools are for.

This is why it’s difficult to figure out what to do with schools right now. We don’t have the resources to do all the weird things that schools used to do. (Smaller class sizes + staff with legit medical exemptions – painful state budgets – meaningful federal support = funding disaster.)

Schools are already weird compromise institutions. We should all expect it to take another weird compromise to make this next school year work.

# Why my students like Deltamath

My survey question to 8th Graders was, if you liked Deltamath (a math practice site) as a distance learning tool, what did you like about Deltamath?

Here are the responses:

• The very clear examples and how it is easy and not glitchy
• There was always an example and there was a goal to work towards
•  I liked that if you didn’t understand something, it had examples to show you.
•  It felt totally normal like the homework we would usually have
•  Examples are clear easy to answer
•  It gave examples, helpful videos, and it was concrete. I also liked that it let you know if you were right or not.
•  I liked that it gave me a chance to put what I learned to use
•  I feel like the subjects are not super difficult but the problems are a good workout for ur brain
•  Also it tells you if you are right or wrong, so it helps you check answers
•  When it would show graphs and it would show you what you are trying to figure out.
• Also that it explains what u do wrong after you get it wrong
•  It was fun and interactive, shifting to give you easier/harder questions if you were correct or incorrect.

By the way this last one is not true, Deltamath does not shift to giving you easier or harder questions. There is something psychologically fascinating about thinking that the software, which is essentially a random problem generator, is actually adapting to the student responses.

In any event, listen to what the students are saying: examples, examples, examples.

Update: Here are some more comments from students about Deltamath. (I lightly edited for legibility.)

• Deltamath works well and is good for homework
•  I liked how Deltamath explained the problem if you didn’t understand it. Definitely my favorite out of all the tools we’ve used .
• It’s just easier than having to use paper and pen if i’m already on my computer in class
• I like Deltamath because I am very familiar with and because it provides examples which are helpful for certain confusion topics.
• It’s very organized which isn’t the case for a lot of other classes assignments
• It’s  also easier to work with other people
•  I’m kinda neutral on Deltamath, but I also feel like its a good way to learn
• I liked Classkick more, I’m not sure why though . I really don’t know why i think it may have just been the layout of the website or maybe just how you could do more types of assignments .
• I have no opinion .
• I really like getting the answer to the problem as soon as I solve them, like it’s really nice to have to get 5 questions right and learn what your doing wrong along the way instead of answering on work sheets and not being quite sure what your doing right until later .
•  I like Deltamath because it is easy to use and it gives examples of question with step by step solving.

I asked students if they felt it was frustrating when they got something wrong. Here’s what they said to that.

•  Only if it takes away points .
• Deltamath can be frustrating when you get it wrong and there’s a penalty but otherwise it’s not that frustrating .

Update to the update: here’s my other algebra class’s thoughts:

• I love it, it is very organized
• I liked the explanatory feature that it provided. Videos, examples etc…
• I like Deltamath. Off the top of my head I can’t think of any part that is frustrating/not useful.
• I think it was overall fine but bit less interactive than Desmos.
• Delta math was my favorite because the questions were clear and although it wasn’t as visual as Desmos it still had some visual elements.
• I like Deltamath a lot it’s really simple and easy to navigate
• Desmos>>>>>>Deltamth because for me it helps to visualize it and Desmos does that
• It was decent I mean the problems weren’t hard at all and I could complete them in the first 15 minutes of an asynchronous period. But Deltmath it self was an easy website to use.
• I like it because it is easy to use and gives you clear feedback. And I feel that Classkick is hard to use and not great for online learning
• I liked Deltamath because it was easy to understand what we were supposed to do and  when it was due.
• Delta math was really good. The only thing that was a little frustrating was typing answers on keyboard. But otherwise it was very helpful, especially the help feature where it shows examples.

As a final question, I asked this class if they remembered times when they got frustrated and stopped working on the assignment. Do you remember which website you were using when you gave up on the assignment?

• yes, on classkick
• Yes, delta math, a few times actually
• no not really
• I think I got frustrated and stopped deltamath once
• Yes a few times
• Only a few times
• Yes classkick
• That never really happened to me
• But I was very tired
• mostly classkick
• Yes. But I do not remember. It was not because of the site. More that I forgot about the assignment.
• desmos
• Sometimes I had trouble using classkick because it was  very technical and there were no specific inputs

Some feedback makes kids give up, stop thinking, or feel bad. In my view, this is almost always feedback that doesn’t help learning. And this is why so much auto-grading is bad feedback — it doesn’t help learning. (In general, motivation is tangled up with success in ways it’s difficult to separate.)

Auto-graded work sometimes makes kids feel bad. This is when the auto-grading doesn’t lead to learning, or makes it seem like learning will be impossible. It’s not exactly mysterious why this is. Most of the time when a computer tells you that something is wrong, that’s it. So you’re wrong. What are you supposed to do with that information, as a learner? If you knew how to do it right, you’d have done it right.

What would the ideal learner do when they get the “wrong answer” info? In some cases, they’d take a close look at their steps and try to suss out the error, essentially discovering the correct way to solve the problem on their own. But in a lot of cases, kids get a question wrong because they don’t know how to do it, or they fundamentally misunderstand the problem. An ideal learner in that case would seek out the information they’re missing, from a text, a video, a friend or a teacher.

Auto-grading in my experience works best when it makes those ideal behaviors easier. I sometimes play around on the Art of Problem Solving’s Alcumus site, just for fun. It automatically tells me if I’ve said the right answer or not (though it gives me two chances and it lets me give up if I want). Then, there’s always a worked-out solution provided. It’s right there, waiting for me to read it. And then, it gives me a chance to rate the quality of the explanation (which I find empowering in some cases).

The first incorrect notice gives me a chance to discover my own mistake and learn something from it. The second incorrect notice gives me a chance to study an example. And then I have a chance to practice similar problems (because the computer will continue to provide them). It feels very oriented towards growth. I can’t solve every problem on that site right now, but I’m confident that with enough time I could.

Deltamath does this nicely as well, though of course not every student reads every explanation or watches every video. It works best in a classroom, where students can ask each other or me if they get something wrong — again, it’s using auto-grading in a context that makes it even easier to act as an ideal student would.

I’d also like to suggest that there isn’t a meaningful difference between auto-grading and a lot of the “insta” feedback that kids get in current Desmos activities. If a kid understands what a graph means, then they understand that their answer didn’t produce the correct graph. If they don’t understand why, you’ll see those same giving up activities that auto-grading can produce — or they’ll do guess and check with the graph until they get a correct answer, which in some cases is not a bad idea — get the answer, and then try to figure out why it’s correct. In either event, Desmos currently employs a great deal of de facto auto-grading in their activities.

One way Desmos could help is by making it easy for teachers to connect students to learning. You might make it easy for teachers to attach examples or explanations to a wrong answer. You might make it easy for students to ask the teacher a question via a textbox if they get an answer wrong and they can’t figure out the problem. You might enable teachers to include a brief explanation with the wrong answer, and then let kids rate the quality of that explanation. (Really, check out Alcumus.)

There are smart ways to do auto-grading, I think. The smartest way, though, is to make sure it’s happening in the context of a lot of interaction between students and a teacher.

# Dan Anderson Made Me Do It

Dan started it here, describing a day in the life of a math teacher these days.

Well, here I am, typing this while my kids are playing with a pair of broken laptops at my feet. Apparently my wife and I have been on our laptops enough that it’s inspired our children to play along.

I was hoping to do some work now, but my daughter Shuli (aged 2) refused to nap. Right now she grabbed Yosef’s face (he’s 5) and pulled on his cheeks as hard as she could. I am watching this disaster unfold as I type. Yosef just kicked her in the face. Shuli went on his back and slapped him.

Now, Shuli is climbing on me, and I’m typing while elbowing her, to keep her off the keyboard. This is more-or-less how it is.

“Which bomputer is the dirty one?” she asks. “Yosef is not giving me a bomputer?”

I just heard my toast ding. While I typed this, Yosef grabbed her first and she yelped. Now they’re slapping each other again. Should I get my toast?

I teach soon. I taught a live 4th Grade class this morning; this afternoon it’s my geometry students. The other three classes had assignments that (in principle) they’re working on.

Finding time to put the assignments together is, obviously, a challenge. Yosef is now holding up a pillow and hitting Shuli with it while she runs into it, like a blocking drill. More slapping, more yelling. “Get off me, you stupid jet pant,” he says.

“Is Shuli taking a nap?” he asks. “She really needs one.” How about we all take a nap, kid?

Since I can’t put together any of the assignments during the day, I’ve moved to the night. Last night I put on Netflix (I can’t even remember what) and set up all of today’s assignments. Oh, yeah, it was a Jim Gaffigan stand-up thing.

Here was one of his jokes: “If you want to know what it’s like to have four kids, imagine that you’re drowning…and then someone hands you a baby.”

“At the count of three, go to where Mommy is standing,” the boy says to the girl.

“Boo!” they shout at my wife.

After my 4th Grade class I went to the grocery store today. We’re in NYC where apparently you have to fight tooth and nail with your neighbors to get a delivery slot. We live close to the grocery store, so after class I took out the granny cart and went to the store to replenish our fridge. I managed to spend a couple hundred dollars, which makes me glad that my wife and I still have our teaching jobs. This would all be infinitely harder if we were out of work.

When I came back, my wife was in a meeting and the kids were wrapping up their first burst of TV time. (Sid the Science Kid and Daniel Tiger are the current offerings, but it changes weekly.) I checked in on the Google Classroom for my 3rd Graders. Engagement in that class had been low, so I’ve started posting half of a joke and asking students to guess the punchline.

“Stop running,” my wife and I yell to Yosef at the same time. I look up from the computer I’m typing this at. Our downstairs neighbors aren’t thrilled with the nose from our apartment, and I can’t blame them. I don’t like it either. When this is all over, we’re going to take our kids to a specialist who can teach them how to walk without stomping.

It’s raining today, is the trouble. (“STOP RUNNING,” this time I yell it.) We live in a seven-floor building that is part of a complex of four, and there is a nice big yard behind it. Usually I take the kids out there where they can run, jump, search for broken glass and used bottles, kick a ball around. I’ve taken to giving them splash time in muddy puddles on rainy days, but they get covered in mud and get too cold to be out after just twenty minutes; it’s not worth it.

I’ve spent the last few weeks saying that this whole thing was unsustainable, but it’s been six weeks now and that doesn’t feel quite right. This is sustainable, we can keep doing it. It’s just a grind, and a lot of days it sucks.
