this guy is the worst teacher i've ever had

very smart man, yet very unclear. has a very liberal grading curve, which helps boost grade. however, i would never take this teacher again if i had the choice. difficult to follow in class discussions.

DO NOT TAKE THIS PROFESSOR. He gives no help. He does not scale. I got a 59 on an exam and he would not raise it to a 60 so I had to drop the class and retake it with another teacher. He has his head up his ass while teaching and basically likes to hear the sound of his own voice. God forbid if you have a question, he can't comprehend that not everyone is a math genius like he. Oh yeah, wore the same outfit to every class as well. If you currently have him, take notice.

This guy was horrible. Never stopped to help anyone, if you asked him to slow down, he would look at you and just go faster. Dont get me wrong this guy is very smart but he can't teach you anything. If you take his class youll spend most of the time in the math lab trying to figure out what he just did

Quite possibly the worse professor I have ever had. Avoid him at all costs.... "any questions or illegible things?"

DON'T TAKE THIS CLASS unless you feel like taking the book and teaching yourself Finite Math. Doesn't explain anything and goes through the problems so fast that you don't even know what he just did. Class had 30+ on first day and there were 4 people at the final... what does that tell you?

I'm pretty sure a middle school student could do a better job of teaching. Do NOT take a course with this guy.

Yeah so I took this guy for Finite Math. Hes the teacher..and you know the type...that understands the information so well that he cant understand ppl who dont. If u ask him to explain soemthing..hell give you an even more complicated answer. Yeah finite math is somewhat easy..but this guy makes it a lot harder. Not recommended.

This is what Prof. Rosenthal does: during class, he stands up at the board and talks to himself, from the beginning to the end. He doesn't take attendance or collect or hand back homework. He just writes on the board and says random things about math. Do your best to avoid him unless you are good at math.

Cliche in that he has chalk dust all over his face and pants & he KNOWS his math. However, probably the WORST professor. He doesn't know how to teach. Had to drop class. Tried to ask questions, couldn't explain anything. Didn't inform us we had to have online book that cost me $100. Never explained anything no matter how hard we tried to ask.

I took prof Rosenthal in the fall 2010. He's the worst professor at Salem State! He doesn't care about his students you could go to his office every day and still barely get a D. I graduated school with a 3.95 gpa do yourself a favor take MAT 108 or any math with J. Lampes you'll be glad you did. This guy hates life!

WORST PROFESSOR EVER!!!!

Terrible teacher, does not care how students are doing in the class or try to help them. The teacher makes simple topics confusing.

There are not words to describe how bad he is. It is an absolute guarantee that he will be the worst professor you've ever had. This is coming from someone that NEVER writes bad reviews. If he wasn't so nice, I would have thrown things at him in class.

The best Math teacher on campus.

It was just the worst. If you plan on taking an online class, you'd expect online tests, right? Well not here! He makes you come in on a day of his choice (unless you can get him another day) and you take it in class. I don't know about you, but that's not an online class. He's rarely any help and he sounds like a drone. Just don't do it.

I'm really good at math, but this professor has made it very difficult to learn anything. He talks to himself while writing messy notes on the chalkboard. Very hard to follow. I taught myself to the best of my ability online to somewhat understand the contents of the course. Everyone fails the tests, so he does scale them.

worst teacher I've ever had. He doesn't teach at all, he goes over questions on the board but it's really hard to follow & he doesn't explain himself or if he does, he expects you to know exactly what he's doing. Only thing that was helpful was the review questions for tests and the answers to them are online. Don't take his class.

Dont take this class. I dropped out the first day. and the online book access is pretty expensive.

This class was absolutely awful. 5 students dropped the class after I did as well. He doesn't help and keeps referencing the book if you needed help. Do NOT take this class. It is not worth it.

Worst. Professor. Ever. I am including high school and my community college as well. I had to take this class last second and I trust RMP, I wouldn't have taken him. He does not help you when asked. He is disorganized, he is very rude to students. He insulted me in front of the entire class for getting extra help. DO NOT TAKE HIM. SAVE YOURSELF.

Awful teacher. Doesn't care how his students are doing in class and doesn't answer any questions asked. If you take this class you will most likely fail.

Day 1 consisted of watching him speak for 90 minutes without taking a breath. It was extremely difficult to determine what he was exactly going over due to his constant conversation with the chalk board. Intermittently he would turn around and ask if we had questions. If you aren't a whiz at math or just older like I am, do not take this course.

Absolutely horrible. He is knowledgeable about the subject but get ready to teach yourself the material. He assigns homework on material he's barely covered so I end up spending hours trying to finish the homework because he doesn't teach! He flies through lectures, even if it is on new material. Honestly one of the worst professors I have ever had

Awful. Lectures become obscure tangents of un-related concepts and introduced many Calc 2 and 3 concepts before we learned Calc 1. HW was all online, and I could never reach him outside of class. I ended up having to buy an online tutor to help me even get through. A scale of 50% or more being a passing grade should say enough.

Very messy writing, always chooses the most complicated way to solve problems, does not teach and only does examples on the board. You will need to teach yourself first, THEN practice in lecture. Lots of homework, $100 mathlab required, keeps grades to himself so you're clueless. Even multiple math majors could not figure out some work from calc1!

Moves way too fast, and doesn't seem to care whether or not you learn the material. I've always struggled with math, so at first I thought it was just me, but I know some math majors who felt the same way. I knew I'd be dropping the class after another student said they didn't understand what he was explaining, and he said that wasn't his problem.

This professor does online classes but wants you to do your tests at the testing center. He's never available for extra help. No one in the online class got higher than a C-

Would not recommend unless you already know what youre doing for the class. Illegible handwriting and he doesnt go over what he talks about, just expects you to understand. Brilliant guy, terrible professor.

Professor Rosenthal must have once been a brilliant man, but he cannot teach. His handwriting is illegible both in class and through his online lectures, and his explanations of problems don't exist. My class started with around 30 students and ended with less than half. People would skip just to go to the math lab for help. Save your GPA dont take

Worst professor I have ever had, doesnt explain anything

Terrible professor, worst i have taken here! took the class for 2 weeks then dropped it because he was so bad

Teaches you the most Confusing methods of doing problems

Ive always loved maths until this time

Unless you've study hieroglyphics for 5 years, you will not understand a single thing this man writes, nor will you understand his complex lectures and teaching. He's smart without a doubt, but he's not very cut out for teaching.

Save your GPA and DO NOT take his class. If you can take someone else, do it.

He talks a lot in class and sometimes one can get bored very easily if you are confused you are going to fail each class you will learn something different

I used to adore my math classes. I'm a numbers guy so I've always had ease with math classes. This man, however, has dumbfounded me and I barely made it through this. Awkward teaching, annoying homework, and tests that if you don't study hard for, YOU WILL FAIL! And I was basically the only one who even showed up to his classes. Avoid at all costs!

I Highly recommend that you do NOT take him. He is such an awful teacher, every class he gets straight to writing on the board and does not explain anything. The test are 60% of your grade and he assigned homework almost everyday, the later you submit the more point he takes off... Worst professor at SSU

THE WORST PROFESSOR! He shouldn't even be allowed to teach anymore because you don't even learn anything... and it is clear I'm not the only one who would agree with that

Just awful seriously. I love Math but with this professor just NO. I tried emailing him and he said everything is there on the assignment. I ended up dropping the class because it would mess up my GPA. Just do not take this professor.

This professor exemplifies everything that's wrong with tenure.

Do not do this to yourself. I love math and I dropped the class. It was just horrible

I was going to give a lot of info about why this class is so bad, but I am limited to 350 characters. I will leave it at this. You know the horror movies where people go into the haunted house and you're watching saying to yourself "well that characters going to die". Arthur Rosenthal's class is the haunted house. good luck.

This was the worst class I've ever taken. I tried to stick it out for the whole semester, but there was no way. You can ask him a question and he'll go into detail and answer everything BUT the questions. Imagine everything that can be bad about a professor and put it all into one. It's him.

Probably as bad as it comes when it comes to professors. Only reason I passed was because of his insane scaling system. Also his hand writing is not readable.

Just all around terrible professor, doesnt care about how you do on exams, and only gives you 60 minutes to complete an exam. Avoid this man like Covid

This guy may be the worst person that's ever lived. He is just a bad grade waiting to happen. This will definitely tank your GPA and you'll want to seek therapy after his classes. His lectures are just scrambled and uses advanced concepts to teach this. I don't mind math but this class makes me just hate it. I wish I could write more but Im limited

Arthur must really enjoy screwing over every single person that has signed up for this class over the years because it is above and beyond the hardest math class in the entire school. Grade is based completely on three exams - stay away from this class. Hopefully somebody from administration sees this page one day and begins a full investigation.

Guy is a joke. The fact that a University is willingly paying this guy to teach is actually comical. Doesn't care about the students and if you decided you wanted to sign up for the online class good luck because it is physically impossible to pass. He doesn't care. Simple.

This class is a waste of my tuition and my time. I'm officially calling for this mans termination as he should never have a job for as long as he lives. He doesn't deserve to be paid a dime as he is just robbing this university blind. President Keenan should really look into this guy as he is robbing the school of their money. Overall just bad guy.

If you want to go through hell during a semester take this class

all of the ratings on here are true, do NOT take this class. you might have a chance to pass if you can teach yourself, however with the material he assigns it's almost impossible. good luck if you unwillingly get put into this class

One of the worst math professors in Salem state, advisors and other faculty know he is not good at his job at all but have done nothing to remove him from his position which he doesn't deserve. If his grading wasn't scaled nobody would pass. If this is one of your required courses just go to math lab to help you, don't waste your time in his class

I went through hell an back in this class, I spent night and days trying to understand this professor, I tried emailing for help but it felt like I was reading a novel, I just always got lost and confused along the way of reading his emails trying to find the help I thought I was getting. save your mental health.

Welcome to the end of your sanity. I love the struggle of math, but even Rosenthal's class had me wanting to throw hands with the wall, since Rosenthal often overcomplicates the math. One redeeming aspect is that he's always willing to help. The beginning is deceptive, since it's really simple, but turns into overcomplicated mathematics. Good luck.

One of the worst professor's I've had in my life. While make attempts to help if you ask for it. In class both over and under explains how to solve a problem. Doesn't teach any calculator shortcuts for the equations, but will show you the excel shortcuts (which you can't use on the test as it's all paper). Avoid the class if possible.

Horrible, attendance is not taking at the beginning of the lecture, nor any lecture. The professor sticks to one question on a past quiz for the entire lecture so you leave with the same knowledge walking in. The class is finals heavy, quizzes are about a minimum of 20% of your grade, while finals are 80%. Much more to say but not recommended.

terrible professor and does not care about his students, taking his online class he does not answer his emails quickly at all, and if he does he responds with an emotionless robotic answer in a whole book of useless details that do not answer your question. take the class with somebody else.

Honestly, the only reason I passed this class is because of his insane scaling system but other than that, this class was horrible. He would come into class and just start writing on the board without any explanation, basically talking to himself. Exams were 80% of the grade meanwhile the homework was 20% of the grade, speaks for itself.

He talked to himself the whole class period. Never took attendance. Tests were worth 80% of our grade which is insane. Never communicated. Always late.

Clearly a smart and sweet guy, but a truly horrible professor. Classes are awkward and confusing for the 3-4 people who bother to show up. Asking for help is useless because of his complete inability to communicate information or even hold a basic conversation.
