Given that she's new to teaching, she's all right. Sometimes unclear, prone to bad handwriting, but her exams are easy and she's fair with grading. Don't bother with the textbook- haven't bought/opened one so far and I'm getting an A. Summary: not a wonderful teacher, but the class is so easy it doesn't matter much.

Dr. Arnaboldi explains the material very well. This class in particular was nice because it pushed for library research culminating in a final project that is intended to be installed on campus. There were no exams and only simple assignments that went toward your final project. It was a new project, so the direction was a bit unclear at times.

Treats her one credit class like we all want to study coral reef and eventually become professors on this subject. It's not that serious, I presume most of us took this class for the natural science credit. Do not take her class. Her exams are like 50% of lecture and 50% random facts on the topic of coral reefs.

Her video lectures were poorly structured, with frequent jumps between concepts. Slides with excessive text were flashed for a few seconds, while images or graphs were displayed for extended periods. I frequently had to rewind to grasp the instructor's rapid-fire explanations, which often bore no relation to the slides. She seems passionate, but..

Arnabaldi provides a truly frustrating experience. Final project was a multi-page single spaced paper along with an activity. Spent quality time on it to be told it was "incomplete at best", she ignored parts of my project then marked them as missing on the rubric. Overall a careless instructor I will be avoiding at all costs going forward.

I would not recommend this professor for any classes. I have taken her for many earth classes and I did not enjoy any of them. A lot of the quizzes and exams contain information not found in lectures. The work load is way too much for a one credit intro course.

DO NOT TAKE THIS CLASS! Professor Arnaboldi treats this class like it is worth 4 credits and the workload is ridiculous for a 1-credit class that most people take to get natural science distributions out of the way. I am taking 17 credits this semester and this class was the most work I had through the first half of the semester. Steer clear.

Professor Arnaboldi is the worst professor I've had at Michigan. A 1-credit intro to coral reefs class has caused me more stress than any of my 4-credit major classes. She treats the class like we are studying to become marine biologists. The 2 in person exams are based on random things she says in lecture and are way too difficult for earth 100.

If you show up you'll be fine. She does test a lot about what she talks about instead of what's on the slides (expected), but the exams are very easy. Barely paid attention and got a decent grade. Recommend if you need an extra credit. I will say there is an annoying amount of outside of class work for a 1 credit class but it's all severely easy.

Lots of homework

Dr. Arnaboldi was such a great professor. Almost all assignments were optional (daily quizzes, free-response questions, etc.), but they were good practice for understanding the material. She was super helpful and would make time to explain any confusing material. The class material itself was super interesting and fun to learn about.

Loved taking this class! There were many opportunities to get the grade that you wanted, and you could never lose points because the grading scale only goes up. If I was a freshman looking for an easy A and a fun class I would take Earth 156 a hundred times over again.

I could tell Arnaboldi really cared about the content, but lectures were pretty long and sometimes boring if you aren't into oceanography. SUPER easy A with lots of opportunities for credit, most information can be googled though. Would recommend for natural science credit.

Missed out on an A threshold by less than 10 points when I got well above the class average on the last 2 exams and had almost 1,000 more points than the average person in class
