  1. The aops intermediate is all algebra; the precalc is trigonometry and an intro to linear algebra. They will match different parts of a standard precalc course.
  2. A few colleges are still saying they're going to be back. Very few of their instructors believe them and (in my academics facebook group) we are ALL planning not only to be online for the rest of the semester but summer as well. We are still sticking our fingers in our ears and going LA LA LA LA LA with respect to the possibility of Fall ALSO being online.
  3. I'll be incredibly surprised if we have any in-person classes this summer.
  4. At this moment, a lot of publishers are offering free access until the end of the semester.

  6. Yeah, I have some algebra classes where what we're teaching is "can you factor" "can you solve equations" things like that. There just isn't a lot of room for creative assessments that can't be gamed there. I have no real idea for you. What I can say is that I've added enough problems in the online homework system where you have to work in showing your steps and used them as prerequisites for other assignments that someone who isn't actually doing a fair amount of the work themselves can't get a decent homework score. In the first two exams, they were MUCH more highly correlated to homework (correlation coefficient around .6, and if I delete a couple of outliers who have great test scores but don't do homework because they already knew the material, it's more like .75) than they had been before. I might just put the exam through the homework system and require the homework assignments as prerequisites. Is it fair? Hell naw. But I don't think anyone will be able to earn a "C" who wouldn't have hit at least a 55% or so otherwise, and under the circumstances that's the best I can do.
  7. A precalc course will usually teach trig from scratch unless it's an accelerated precalc + calc A course. It won't harm him to not have seen it before although some exposure is helpful. You used to be able to see the complete TOC on Pearson's website but it's not coming up in a quick search. I know I'd typed out before what I thought was essential but 😕
  8. I agree. But I have so many students come in out of high school calc and apparently all they learned was how to take a derivative of a polynomial. Not that they know what they are ... if you ask them the slope of the tangent line at a point, they'll say "huh?" unless you say 'that means f'(a)'. But by golly they can apply the power rule.
  9. A lot of times, "makes it harder than it needs to be" = "not cookbook", yeah. Is it possible to find a different tutor?
  10. I really like Thomas -- he has some great questions -- but I'd definitely put it on the "more rigorous" side. The problems really make you think about WHY things are true. None of the choices you've listed are weak.
  11. The complete book isn't enough? There's a lot more examples in the earlier part of the chapter: You can also download the student solutions manual and a workbook for both the beginning half and the intermediate half.
  12. I had a similarly depressing section. One B, two C's, and the rest failed. (The homeschooled high school student got the B) My other section of the same course had several A's ... this one just had a huge amount of not. doing. any. work. Like, there were only two people with homework averages over 75% in the online system with unlimited attempts.
  13. There are curricula that order it that way and I don't think it's *wrong* to do it. But I agree about using the book in the author's order without a compelling reason.
  14. Hi Dicentra, I found a great book (Uncle Tungsten by Oliver Sacks) that I'd highly recommend as a living book resource for chemistry. I'm not sure where it would fit -- maybe in the "other resources" -- but I do think there's a lot of good chemistry in it.
  15. I haven't seen these recommended before, and I only stumbled on to them. I'm using MyOpenMath in a class this semester -- it's a free online learning system. They also have self-study courses available for pre-algebra up through pre-calculus, linked here: There are two options for trigonometry -- the CK-12 text teaches with right triangles first, the other with unit circle first.
