Has clear lectures and is very thorough with them. You need to be focused if you want to understand, and you need to consistently look over your notes so you don't fall behind. He goes through the presentations quickly, however they are online if you want to see them later. He has a cute little laugh too.
He was one of my best professors in first year. He is very clear while teaching, however he does tend to go a little bit to fast with his slides. The textbook you need only for the assignments and the recommended homework questions which I found very helpful. Overall advice DO NOT miss his lectures, do the work and you will be more than fine.
Goes through slides way too quickly and doesn't explain things very well. It's obvious he knows what he's talking about, but it seems he doesn't know how to explain it to people who don't know as much as he does. Only plus is that he posts practice tests online which are practically identical to the real thing. Overall, I'd recommend against him.
Discrete math. I fell asleep a couple times in lectures. Quite boring. Talks fast. Very smart. Average at teaching. The textbook is so important.
He's extremely hard to understand. He introduces topics without an introduction and uses terms without defining them. His lectures are mainly examples that are difficult to follow. He does try to clarify some things however that still doesn't help clarify the whole lecture itself. If you take his class get ready to rely on the book to teach you.
Very fast during lectures doesn''t give students time to understand concept. Bad Examples only using numbers that will never be given on a test. A lot of extra information you don''t know. He doesn''t explain all his steps during the lecture expecting us to know what he did from one step to another. The textbook will help you learn more than the prof
Best professor!!!
His lectures are extremely boring, doesnt do examples in class and uses very big words without telling you the meaning. If you go to his lectures u will have to depend on the book, becuase u will either fall asleep or not understand
Can't teach properly at all, worst calc teacher ever makes mistakes and just confueses everyone. Makes simple stuff harder can't learn anything his notes are useless
Well he was a rather interesting professor. He's definitely willing to help you out if you ask or it, so I have to give him marks there, otherwise he's the most useless professor in the universe! His writing is messy, he is unclear and he overcomplicates instead of simplify. Don't even go to his lectures. You're better of learning from the book.
Over complicated everything. Made up questions on the spot in class sometimes not even knowing if his answer was correct. Writing is atrocious, which is unfortunate considering there are no accompanying slides or notes. Helpful if you go to his office hours though.
Simply opened the textbook beside him and copied it word for word every lecture.
Good with marks. He is a really nice person. Not the best when it comes to teaching
He simply cannot teach. His lectures format is: open book, poorly reward sentences, change the examples into something he isn't sure about and unsolvable, confusing everyone with his horrible examples, calligraphy and explanations. Student learn more not going to class. He has a really funny laugh though. Attend other professors lectures.
Funny guy, Makes up his own examples on the spot, and if they dont work out the way he expected, he tells the class to "imagine there is a one here " and so on. Constantly corrects his own examples, often after a student pointed out a mistake he made many long steps ago. Hes a nice guy though, and will be happy to help if you come to him.
Doesn't explain theories at all and doesn't help in office hours. Copied questions straight from the book and never explained them. Made many mistakes during lectures. My advice is read Alvarez's slides and do practice problems. Tests are fairly easy. Be prepared to do a lot of self learning. Textbook really helps.
urggg don't even bother going to his lectures, you'll be even more confused! All he does is prove equations and really doesn't explain anything! His writing is so messy, you can't even read it. You're best off learning by yourself!!!! BEST OF LUCK! CALC IS HARRRDDDD
Lectures are very vague, little to no test preparation.
Rushes thought the slides so fast that theres not a chance to take proper notes. Even the posted notes online have you jumping between alternative files to see whats missing from them.
If you're taken MTH 110 for the first time you are better off not having him. But his final exam is almost identical to the practice he gives. It's the same in terms of type of question. When I went for extra help he couldn'twouldn't go beyond the examples in his slides to explain certain concepts.
MTH210 - a mix of different unrelated fields. His EVERY lecture from slides, all of his examples are solved on those slides and he just reads them (some slides have mistakes so pay attention). Very boring class - students are prone to falling asleep. Tries to joke around. His exams are very similar to posted practice ones.
Nothing is explained through steps/hard to follow. Does not interact with students or excite them. you will fall asleep.
In general people in my class didn't like Horowitz. They'd say "He goes to fast" or "doesn't explain what he's doing". I on the other hand found he desribed exactly what he was doing as he was doing it. Perhaps people are too expecting of understanding a concept perfectly after first seeing it. To do well, you will have to read the textbook anyways
Okay people dont like him, hes not that bad. I like the guy but hes not the best prof. He cant write at all(its pure chicken scratch) , gets some friends in the other classes to give you their notes. He can sortof explain what hes talking about which is nice. So go to his classes.
Okay people hate him, hes not that bad. I like the guy but hes not the best prof. He cant write at all, gets some friends in the other classes to give you their notes. He can sortof explain what hes talking about which is nice. So go to his classes
Lectures were completely useless. Most students in his class left to attend other lectures. His examples don't work because he doesn't prepare examples that will give you a solution. He learns how to teach on the go.
If you're in Horowitz's lectures to take notes, get ready to scribble up a novel. He is fast but can slow down on request. His lectures are alright but the material is hard to understand given the absence of practical examples. Would not recommend sleeping in class as you'll miss a fair bit. Study for the tests as they constitute most of your mark.
Jonah Horowitz isn't a bad prof but sometimes his explanations of examples aren't just good enough. He skips a couple of steps in his examples which could throw some people off (like me). Ended up studying the entire course by myself and the textbook is VERY useful. If you don't understand something from the textbook, YouTube it. Good luck!
Honestly, he is very theory based and doesn't explain, but assumes you understand the theory. With some extra self-reading. you can really start to do well in this course. Then, once you start to understand what Horowitz is doing, you know you have mastered the content at that point.
Had him for MTH 141, MTH 140 and am taking him again for MTH 240 Hes a good prof, he has major issues when it comes to taking notes so keep your ears open and stop texting in class and maybe you might understand whats going on. I highly suggest getting notes from another class but do attend he says alot of valuable information.
He does not explain material well, lectures were empty because everyone went to the better profs.
There are known unknowns and there are also unknown unknowns. The unknown that every student should know is that Dr. Horowitz has zero intention to teach properly and he goes over course material as if every student has a phd.
Really confusing mathematician. His lectures were confusing and main concepts were barely conveyed
A little bias because it was basically grade 12 calculus review so you went in already knowing the material, but honestly though a little condescending he does teach to test. If you go through his examples you will and actually listen to his lectures you will get 90+ guaranteed. HOWEVER Majed does tell you basically what's on the test so go for him
worst prof ever and he replies to his emails with an attitude
LECTURE CANCELLED, WHOOOO LETS GO, LECTURE CANCELLED AGAIN, EVEN BETTTTEEER. Jonah is the worst, he only does theory, just go to majed's lecture, guarantee A. His lectures are super empty, which is self explanatory. Skip and dip for better profs, not worth your time.
asked him a couple of times via email, and he answered me clearly. he is actually very smart, which many dont know. but when it comes to lecture his methods of explanation are very ineffective. his target audience are those with 90+ in calc in highschool, so his lessons are understood by 15-20 smart people max
if you have real passion for learning the course and obtaining an in-depth knowledge of calculus and linear algebra u should really consider him because he teaching is based on thinking. if you are looking for someone who teaches u to memorize math so that you recite out in a test for bare sake of marks then he is not gonna help you much.
Very helpful with questions in class and during office hours. I don't think that the attitude that others have mentioned is intentional; it's just a personality quirk that occasionally comes through. His handwriting is really bad though.
Had him for MTH 140, 141, 240. He is just a guy who has a genuine passion for math. Clearly qualified and will make you work for your mark. No spoon feeding and you can feel good about getting great marks. Got perfect in all courses thanks to him. Readers beware his handwriting is an acquired taste, so make sure you listen well and make good notes.
The worst prof I've every had! 3 word responses in his emails ie. no it won't or yes it will. Tough course so choose prof carefully and avoid this guy who has obviously lost all interest in teaching!
Jonah Horowitz is one of the profs different than the others. He is not a good teacher, but he writes down the material(not legible though) and he solves many examples and is rather generous in grading. The only thing you have to do is to overview the material beforehand and participate readily. And his classes are not as crowded.
The content itself isn't that difficult, he just overcomplicates his poor explanations. He answers questions unclearly and with sass.
Horrible prof and when you email him he simply replied with a short sentence. No elaboration.
He has the worst hand writing
If you can read his handwriting, youre golden. If hes the only prof teaching that subject the semester you take it, beware. As the only prof, hes allowed to put any question, even unsolvable ones! I had him for the winter term and he screwed us over big time for the final; post-curve left the class average below a 50%. Swap if you can.
Jonah Horowitz is one of the toughest math professors at Ryerson University. His lectures and handwriting are really difficult to understand. He uses tough techniques to solve problems. His midterms are really difficult to solve. I won't recommend him to anyone!!
Professor Horowitz is a tough cookie. Many people don't seem to like him because he teaches quickly. He breezes through examples rapid fire. Other than that major inconvenience to some, he is a perfectly fine, although quite unsympathetic, professor. He replies to emails just as fast as he teaches, goes over review materials. Still a tough class.
Horowitz is not ALL that bad. He is a genuine person and is easily approachable. Sometimes says corny jokes. But now the bad stuff. His handwriting is terrible alt-though you get used to it. He never explains nor shows his steps, he expects you to know it. It may not seem bad, but over time it gets more and more annoying.
He is simply bad and not interactive with students. Avoid if possible
Pros: Very Smart and knowledgable, Very Helpful, Funny (sometimes), Genuine Passion for math and teaching. All in all, he is a nice person and definitely not as bad as people think he is Cons: VERY BAD HANDWRITING (trying to improve so thumbs up for that ), Tough Grader, Unsympathetic, A little fast sometimes(skips a lot of steps), unorganized
My prof for both MTH141 and MTH140; was the absolute worst. Overcomplicates the most simple things and is very hard to understand. Had to teach myself everything. Cannot read his notes, he cant even read them when you ask. Very tough when remarking midterms, dont ask him to remark qs unless you want a lower mark. Please switch profs
had him for mth 140 and 141. he's really bad. he overcomplicates things, his writing is terrible, and his lectures seem unprepared at times. try to get a different prof and if you can't, prepare to teach yourself the whole course.
Mr. Horowitz is notorious for having absolute chickenscratch handwriting. He always skips steps when solving problems and expects the students to understand. When someone asks a question he usually responds in a slightly rude manor. If you end up with him, just go to another professor's lectures.
just an awful person who doesnt care about the class, you, or improving his writing ability
How did he even become a professor with that handwriting...
As a first year student I felt too guilty to skip classes for most of the semester, and that's where I went wrong! This man goes so fast, does not properly explain the material, & no one can understand his handwriting. Once my guilt of skipping left,I taught myself the material & did 10x better on the exam. too bad I figured that out so late.
I asked him for a remark, and he almost took away marks from my test. Apart from that, he's an ok prof and if you pay attention to his lectures, you should be fine.
Blessing
People give him low ratings because his handwriting sucks and doesn't teach the material to them like they're babies. Truth is he teaches University math exactly how it should be- the theory behind concepts and not just doing a exercise after exercise. That's our job. He's very, very precise in his answers when replying to students' questions.
One of the most passionate and intelligent professors you'll have in engineering. His lectures are theory based, if you just looking for a prof to teach you how to solve specific types of problems go to the other classes lecture. If you're passionate about math you'll love this guy.
He does not explain what he's doing whatsoever, skips way too many steps, and just expects you to know what he's doing. Idk how he's a teacher because he really doesn't teach, he just does his thing. When you ask a question he makes you look stupid instead of considering the fact we're seeing all this for the first time. The point? Just self teach
skip class? you wont pass. Attend the class? you still wont pass. honestly he was the course coordinator and both mth140 and 141 were terrible unorganized asf. the tests are terrible, nothing like what we learnt. if he is still the course coordinator rip.
Extremely boring and a has monotone voice for the entire lecture. Only time he laughs is when he makes a mistake. He has a very snappy personality, if you were to ask him a question that he thinks has an obvious answer he would reply in a rude tone. Also, he admits to making tests have questions new to students to make it more unpredictable.
A lot of people have been giving him very bad reviews, but I think some of this hate isn't really deserved. Transitioning a calculus course online is no doubt very difficult to get right, and since Mr. Horowitz is the coordinator for the course, he gets all the blame from the students. Hes not that bad, and he seems to try to make things better.
worst course coordinator in any course ever makes test questions unpredictable during a pandemic extremely stressful
He is so uncooperative and does not reply to his email or what not. I wish I can give a 0 rating. He tries to compete with the students , if students give him a reason he just says sorry it does not explain anything and just moves on without replying to you. Avoid at all costs
Mocks students for asking for grades for a test that's 2 months old, in order to calculate marks for drop deadline
alot of people are hating on him because of the transition to online. i am a previous student of his and he is not a bad prf. dont listen to the first years of 2020-2021 because they dont know. hes a good guy, just overwhelmed by the impatient first years
AVOID!
Missed class? You are dead!!! Attended class??? Still dead!!! Terribly messy with work organization. When questions are asked, the answers seem so complicated that you feel like giving up. Overcomplicates easy stuff! Honestly speaking, I have got my mark in this subject just from learning on YouTube. I barely attended any class at the end!
Dont ever go to this prof. All he does is degrade students and their feelings. He does not take student's concerns seriously. All his announcements are basically him complaining about how hard his time is and shame students for being lost ! (in a system that obliges students to self teach and study every course & learn it without the help of prof)
Test are nearly impossible to finish in time given, he probably is the worst test maker I've delt with and he cant take critism.
Horowitz , is a very rude professor , his handwriting is horrendous and he makes the course seem very hard . He is also a very rude coordinator and isnt respectful to students .
Worst prof u can ever have, sadly he was my course coordinator for both MTH141 and 140.
doesn't care about his students at all. doesn't admit to his faults. shames students.
Had him for calculus 1 and not a bad teacher. Tries to answer every question that comes up in class, and he is super specific with his answer. There were many technical difficulties this year, but Horowitz tried his best to listen to our concerns. He really makes you work for your grade.
Misunderstood prof (dw, this isn't Horowitz's burner). Doesn't have the best handwriting but teaches all the theory needed for you to be able to go on and solve problems on your own. Very knowledgeable in field, so he'll answer your questions very precisely. Excellent communication. Don't really see why people think he deserves any rating below a 3
If you're the type of person who is best taught through examples, Horowitz is your prof. He gives a lot of examples and doing some more textbook problems and reading the textbook helped me a lot. Tip for his online class- ignore the people who complain a lot and make use of all the math help Ryerson offers (tutoring and study halls).
MTH141 was not that difficult with him online, he does a lot of examples so you would know what to do with various questions of the same theory. Though this course doesn't really touch on what linear algebra really is, just how to do it, watching a few extra vids and doing lots of textbook problems helps a lot.
This professor is garbage . His handwriting sucks . He doesnt know how to run a course properly with all the rebuttles . He makes exam questions depending on his mood and shames students that they will not be successful engineers . He is the worst professor at Ryerson STAY AWAY AVOID AT ALL COSTS
Dr. Horowitz is a good prof for those who learn well from examples. He starts with theory then solves problems. What I would like to see differently from him is to explain more about what he is doing when solving particular questions because sometimes it's not precise and it's hard for some students to follow because he skips a few steps.
He's a good at lecturing and he teaches all the knowledge that you need to know for tests in a clear way. However, his online tests were very difficult and long, it's very hard to finish on time. Overall, he's a good professor, but he's a very hard marker.
Good luck if you have this lady as your professor. There is so much I want to write here but unfortunately the guidelines will remove my review. If you end up with this woman, try your best to switch to another professor. He has no teaching skills and his grading is very bad. I would highly recommend to inform the Dean to do something.
