### Do you have an efficient way to view student responses to remote assignments allowing them to type math symbols and steps? (Middle + High school)

In a Google doc, one can "Insert/Equation" (marked by $\pi^2$). Then tiny pull-down menus appear in a top bar: Using these menus, I just typed this nonsense:

### Do you have an efficient way to view student responses to remote assignments allowing them to type math symbols and steps? (Middle + High school)

Consider to just review scanned or photographed handwritten homework. Yes, this is not as easy as looking at typed work, but consider: would you require typed work normally? So why now? If your ...

### Is it morally acceptable to complete math homework with a program oneself has written?

TL;DR Yes, as long as the teacher didn't explicitly forbid it, you wrote the mathematical core of the program yourself, the technique you are using doesn't twist the intent of the problem. Teacher ...

### Students' Messy Sheets: The Big Problem of Exams and Homeworks

Besides mastering the material in the course one thing that the students have to learn during studies is to communicate mathematics in written form. Almost nobody comes to university and is able to ...

### When Euclid was used as a textbook, what exercises did students do?

Euclid’s Elements was used as a Geometry textbook in essentially the same way that Virgil’s Æneid was used as a Latin textbook. Neither contained exercises anything else pedagogical, and both were ...

### Generating system of equations with unique solutions

Generating systems. The same method that works for linear equations works also for polynomial equations. Starting with a solution in mind (in mathematics and computer science, we call this a planted ...

### Worksheet: Homology in Intro Lin Al

I have a dim memory of a simple exercise I came up with as a TA. It was something like the vector space over the reals of polynomials in two variables, including x^2, y^2, and (x+y)^2. I then asked ...

### Worksheet: Homology in Intro Lin Al

Personally, I think this seems very appropriate. A few points: You might reconsider using a two character name for a vector. $xa$ looks like a multiplication. Perhaps just label the vertices $V_1$,...

### Benefits of students grading each other's (or their own) homework or quizzes?

A benefit that can be expected is to help student realize how important it is to write mathematics in a language (e.g. English; French in my case). I have often been confronted by students who ...
