Pretty fair for chem 111, kicks it up a notch for 2nd semester. She goes on a rampage with the concepts. It's very difficult because she doesnt have enough time to go over many math related problems,and that is whats on the test (averages are very low) She also doesnt know what problems are hard for her students... Good for semester1, not 2.

I had professor Widera for both semesters of chem and her class was extremely tough. Although she is rude, disorganized, rushes through lectures, and does not know how to teach any concepts, it is not impossible to do well in her class. As long as you fully commit to reading the textbook and teaching yourself everything, you will be ok.

Took GenChem 1&2 with her. It isn't that she wants her students to fail, it's that she expects way too much from them. Prepare to do a lot of self-teaching. If you make an effort: come up to the board when she asks for volunteers/go to her office hours, she will recognize your effort, but don't get me wrong, she's TOUGH. Take at your own risk.

The negative reviews here are misleading. best teacher highly recommend! Super friendly and nice. Pretty fast, but you have to if you want to cover everything. Wants you to do well, gives lots of resources. Weekly quizzes but there's a chance to get full pts back/2 tests+1 optional which replaces your lowest test. put in effort and you will be fine

OK so Widera is a FAST teacher. expect to run through 120 slides a lecture and cover about 1.5 topics a week. She does teach well and if you do the work and understand the practice questions she gives you will do fine. You get weekly homework and quizzes that are based on her slides. She just wants to see you apply yourself.

She's so mean for no reason. This is a very difficult class to start with and she only makes it worse. Can be helpful at times but really expects perfection on stuff we went over for 2 minutes. Why become a professor if you're not willing to improve and adapt with your students needs.

If there was a church of chemistry, Widera should be excommunicated from it. She publicly humiliates students, grades disproportionately, and has unclear slides and teaching methods. ALEKS is a financial scam. Only uses the raw score on the ACS final. Don't let a few good experiences silence all the bad ones. AVOID AT ALL COST I BEG U!!!

Idk why she has such a low rating- she's not that bad. She's not a native English speaker so sometimes her sentence structure doesn't make sense but you get the gist of what she's saying. Weekly quizzes but they aren't hard.

she's simply not good at teaching. she just speeds through the slides and expects you to do 32 ALEKS topics on stuff she hasn't covered in like 2 days as if you don't have other classes. i had to teach myself half of the course. would not recommend

Doesn't tell us what the quiz is going to be on or will tell us what it is but complete different topic when taking it. Use the most complicated website for homework.

Yes, the homework site (ALEKs) was a bit much bc she didn't filter topics we didn't need to learn, but overall, she actually taught things we needed to know and was a fair grader. Go to office hours!! Also, her quizzes were every Monday, so don't know what last person was talking abt. If you get to know her, she's a nice person.

I would not have passed General Chemistry if I didn't have some background knowledge. She does gets through the entire syllabus but rushes through some parts. She doesn't care or make accommodations for most circumstances. She can be a really hard professor to work with but if you keep on top of assignments and weekly quizzes, you'll be fine.

Personally, I really enjoyed her class. She has a great sense of humor, and she can explain concepts better than the textbook. Generally, you won't have to memorize much (unless she says to) because she'll give reference tables. Also, the questions on her quizzes/exams are exactly like the ones in the lectures and practice exams, so practice those!

She is horrible as a professor don't take her stay away from her as far as possible.She is bribing her students to take her next semester because she has many seats open. She is absolutely horrible in teaching ,she teaches as if u know the concepts without actually teaching. She Flys through the slides in lectures and u won't understand and thing.

By the end of the course it was extremely easy to study for the ACS because the class prepared us so well for the test. She was also very generous with the curve on the ACS final. She really cares and if you go to her office hours or talk to her after class you'll do well in the class.

Hello, to all adelphi Biology/Biochem students required to take any chemistry course. STAY AWAY from widera. even if Adelphi tells you to take it with Biology to be on track for graduation, you are better off just taking another general education course or remaining at 12 or more credits (if you need full time status for scholarships).don't take!

I had Professor Widera again for gen chem 2 and was adapted to her teaching style. It was more math heavy than gen chem 1 which I personally liked. Even when she was out for a week, we were still able to cover the entire syllabus required for the ACS. Very straightforward in teaching, many problem examples. Please ignore the bad comments.

She's a really good professor who cares, you just have to put in the work. She has extra credit and a top up exam that really helps your grade. She also made sure we finished the Stella bus for the ACS exam

I had her for gen chem 2, and the class was a bit difficult for me since I didn't take gen chem 1. She is nice but I wouldn't take her again since her teaching style is way too fast for my liking. This class isn't an easy A so you have to put the effort.

Easily the worst teaching experience I've had in 13 years of school. Her explanations are unclear, she raises her voice, and she makes students feel stupid instead of supported. Learning feels impossible. This class shows exactly how a teacher should NOT behave. Trust me—without the character limit, I'd write paragraphs about how bad,evil she is.

She's just, no. She has her days where she's doable, but a majority of times she's unapproachable & miserable with her job. She goes through the material too quickly. She also strays away from lecture to complain about her personal life. Do your sanity and your grade a favor, choose a different professor, it's not worth your time with her. BIPOLAR!

Professor Widera is knowledgeable but presents the material in a poor and disorganized way. Be prepared to teach yourself this course and find help. As someone who did not take chem in high school, this was a nightmare. I barely passed this class but the thing that saved me was my participation. She likes to see that you're putting in effort.
