If you enjoy frustration and like to feel like a moron, this is the professor for you. ENJOY!

one word LAZY ok more words unwilling to teach and help the students

Dont take him for 350

Farthest thing from environmental chem. This class sounded cool, but this prof gets do distracted and off topic we never finish on time. The prof also doesn't test on anything he teaches, im not quite sure where it comes from. Class average is an D/F on tests. Don't take this class, save yourself, i wish i would have.

This class is extremely difficult.. It is a 105 chem class and I am honestly shocked with the amount of students in this class that are failing... If this class continues to be like this i would be shocked if anyone passed. 1. he is never prepared 2. talks to himself half the block 3.tests are impossible 4. owl is awful 205 chem students cant do it

Worst teacher I've ever had. DO NOT take this class with him. This isn't even supposed to be an introductory chem class, it's supposed to cover the tenth goal area and my chem major boyfriend couldn't help me with the OWL, which is ridiculous beyond all reason. This guy can't answer a question or stop referring to mother nature. Avoid at all costs.

hard to reach for help and when you do he makes you feel like an idiot ... not taking another class with him

Going to class did not help, all his lectures are on his website which is outdated. He would mention things that would be on the exams, but failed to show a proper way of doing them. Worst teacher I've had.

DON'T TAKE THIS PROF!! He isn't clear about any of the homework assignments or whats on the tests. (we all bombed the first exam!)he laughs at you if you don't understand something, talks down to you. He acts like you are an inconvenience to him.

Dvorak's lectures have NOTHING to do with anything that will be on the exams that he gives. It's all reading out of the book, and a lot of teaching yourself. Lectures are a great time to catch up on sleep or any other homework because there's truly no point in attending the lectures. Labs are decent, but explanation isn't very clear.

In lectures he goes off in tangents about his personal life, or whatever is on his mind at that second. The lectures rarely expand on anything in the book. Lots of internet homework, almost every day. And if you don't understand what the book had to say don't expect to pass the homework. Labs aren't explained either. Just what is said in the manual

Really hard class. Came to class every time but the only reason I passed was thanks to the book and online Youtube videos... Im a straight A student and go my first ever F on an exam. Also, I did horrible on the other exams and I was above average. Don't recommend at all, unless you want to get stressed out.

exams, lectures, homework, labs are NOT relevant. exams weight 60% of your grade, but most of the materials on the exams are not from the homework, lectures and labs, so you cant really study for the exams. he does a very poor job on explaining the materials, when ask to clarify a concept, he dodges and says, well talk about it but will never do

he is the most unorganized professor i have ever had. feels like he doesnt like the subject hes teaching. he never comes to class prepared. he basically read off his unorganized powerpoint in lecture. believe me, you cant study for exams from his powerpoints. if you value the money you paid, take the class with a different teacher if you can

I used to love chemistry and he ruined it for me. He knows what he is talking about, but he cannot teach it. He makes you feel stupid by saying how easy everything is when it is not. The online homework takes a very long time to do so be prepared to spend time on in. He does not do many example problems in classs so be prepared to teach yourself.

He's disrespectful to his students. Almost like he wants his students to fail his class. His feedback is not helpful. Uses vulgar language in class as well as towards students. 10/10 would never take his class again. Wish this class was with a different professor. Felt like I didn't learn the things I needed to in order to succeed in the course.

Horrible class. Tests are super hard half essay and half multiple choice. Labs are super hard too and there is your knowledge assessment on lab. He grade you according to what he feels like. Even presentation on chemistry lab. He only wants you to work on his class 24 hrs.

I had to drop this class after our second exam. I felt that Dvorak made little effort to help me succeed in the class. I really struggled from the beginning, and when I tried to get in contact through email/office hours he was hardly ever available.

I took his class and it was a lot harder than it needed it to be, Aleks HW every 2 days with topics he hasn't taught yet, and his grading is horrendous by taking points off by the smallest detail. I WOULD RUN THE OTHER WAY if you have the option to do so.

I thought Chemistry was easy and fun to learn, but not after taking this class. He is one of the worst teachers I have ever had. ALEKS is frustrating to try to learn, and lectures are super confusing. He doesn't go over important topics in lectures for exams and exams & labs are super difficult. I would avoid having him as a teacher

Not a very good human, nor professor. You can tell he likes chemistry but wasn't meant to teach. He absolutely doesn't care about students. looks down on students A LOT. He expects you to be an expert on chemistry.

This professor seems like he doesn't care what students think or feel, doesn't care what grade they got. His lectures are confusing and there're somethings that are on the exam that he doesn't mention. He is very harsh on exams and especially labs. Avoid him all cost.

I dropped his class after he started a surprise last minute lab and the guy got in my face because I "wasn't measuring water correctly." He even proceeded to forcefully take and throw the beaker I had into the sink only because I didn't think the method of filling the container mattered. No longer felt safe to come back to that class.

I did not realize it was this bad. It is to the point he does not understand his own work and get's the answers wrong. He yelled at a girl due to her ankles showing and he yelled at how my sweatpants were to tight like leggings. He does not care for student's and makes you feel bad. The homework drops you points if you mess it up even once. AVOID!!

Prof forgot we had class today. How disrespectful of him, we pay for this class and he doesnt even show up. Still expects us to take an exam on thursday. AVOID THIS PROFESSOR HE IS NOT THE ONE TO MAKE YOUR LIFE EASY HE IS THERE TO RUIN IT.

one of the worst professors at scsu. absolutely no reason for this man to be tenured. doesn't care about students well being or learning in the slightest. we were supposed to have dr. cama and got stuck with dvorak. DO. NOT. TAKE.

Went to class to get compared from class chem210 saying we were the reason the test scores came back so low. He proceeded to tell us that WE need to focus better. There is to many try hard kids in this class for him to tell us that we needed to focus better. DO NOT TAKE HIM he does not know how to teach his own class and solve his own problems.

i dropped the course shortly after the first test. i was accepted into a different school and i've never been more excited to leave after taking dvorak. he is misogynistic, racist, and makes students feel as if they're not good enough to be in this field. AVOID.

I WILLINGLY put myself two semesters behind for my major so that I could avoid taking him for this class, thats how much I dislike him. He is a bully, who will talk down and belittle you, and will not acknowledge his failings as a teacher even when the whole class "did awful on the exam because we are lazy and unmotivated". Save yourself the time.

I took Dvorak's class last year, and it wasn't good. But geez, I didn't know it had gotten worse this semester. His lectures don't tie into the tests or Labs we were doing. He's disrespectful and doesn't care about what students think. Even the smartest people told me that they either failed or got a max C+. Avoid him and take it in the Spring.

I wish my advisor didn't put me in this class with him. Dvorak is a horrible professor and doesn't really care about his students. His lectures are sloppy and the examples he gives us are useless. Labs are hard and don't tell you what you did wrong and want you to figure it out yourself. Tests have nothing to do with the lecture or ALEKS.

Having Dvorak as my professor for chem has made me very upset. He does not explain his content well and his lectures have nothing to do with the exam. He changes his topic of the lecture instantly and talks about things that make no sense. I regret ever taking him and i'm disappointed that the school seems to not care about the actions of man.

I was sick for 2 weeks and asked if I could take the exam 2 DAYS later than scheduled. He said he was "quite disappointed in me." After getting scores back I noticed EVERYONE ELSE got an extra credit opportunity but me (he never mentioned it). His lectures are confusing (talks about random things), literally nothing good to be said about him. :((((

one of the most incompetent "educators," he has no idea how to teach and has no intentions of learning, if you want to learn and love chemistry he is not the one, I would rather be 1 year behind than take a course with this dude.

Being an A or B student you'd think I'd do okay in this class? Wrong, this professor was the worst one I've ever had my entire life. No one got above a 90 percent in his class and he has over 10 students drop his class. He never thought us what we needed to know and his exams made absolutely no sense. I'm shocked he hasn't been fired yet. AVOID.

So rude, and easily goes on tangents that have nothing to do with the class. I wouldn't wish having him as a professor on my worst enemy

hard to work with. does not follow a schedule, admitted to not knowing how to teach the class, decides then and there when things will happen. he gave us a 3 day notice on our exam once when we weren't even half way finished with the chapters meant to be on the exam. extremely cranky and unprofessional. a handful of students had to report him.

I would avoid this professor!! He was very dismissive to questions. He didn't actually teach the material just read off of slides. I basically learned this class from the textbook. He also didn't give us our grades until the end of the semester so we had no idea what our grades were until the end of the semester.

just study before class , rushes things so its best if ur prepared for the materials

Emphasizes going to lectures, but there's one problem, this dude's lectures are drier than a sand dune in June. Goes on random tangents, and if you ask questions he sometimes makes you feel stupid. Very tough grader on labs and tests, even with an 18 point curve, many people failed. I watched A students struggle to get a C in this class.

Worst Prof I've ever had don't take his courses

This class should not have been as hard as the professor made it. The class was graded on 4 exam and a final which were weighted 70% all together. 15% was labs and the other 15 was the homework. This professor was a tough grader on the lab and would take away points for anything. The exams would have random questions that he never talked about.
