Mark teaches very differently than other professors. There's less examples and more words. He teaches more upon "hows" and "whys" rather then repetitive examples. You don't need a textbook which is good. He records lectures, but attendance is still pretty needed. Expect a lot of written homework. Tests are multiple choice which is a hit or miss.

Literally the worst teacher I have ever had. He created his own lesson plans on how to teach Calc 1 and if you google search one of the terms from his lessons in quotes the only search results are from his lesson plans on how to teach calc. Impossible to get help from anyone because no one outside of class understands what's happening in the class.

Mark is a phenomenal professor. He teaches Calculus a little different but it forced you to really understand the "why" of the concepts, versus just doing a bunch of mindless example problems.

The teacher and the way he teaches are very good. I enjoyed this class actually. However, since this is a specially structured class that is different from a normal pre- calculus, you cannot get enough practice problems outside of class that reflect the types of questions you will encounter. The questions are from the HW, but they tweaked a bit.

Not your typical Calc class, but if you put in the work, you will learn calculus.

THis review only applies for the summer class, which was 6 weeks instead of 15. His 15-week classes are very difficult with a lot of work. But he really does care, and he wants you to learn the material. In 15 weeks, it's doable. In 6 weeks, it's impossible. The workload triples, and it's just too much. Take in fall and spring, avoid in summer.

This class was by far the hardest class I took during the semester. Mark teaches Calc a completely different way than any other math teacher and wrote the textbook himself which makes it confusing to understand and hard to obtain outside help.

Mark is a must take if you actually want to learn math, or need to learn math for your major.

If you don't understand things super quickly do not take this professor. He uses his own book online and teaches the course in his own way. He lectures the whole class and when he asks questions if one person responds he assumes everyone understands why thats the correct answer. He does upload his lectures after class though, which is super helpful

Without a doubt, the worst professor I've had in college. He refuses to post any answers to review problems until 7 pm the night before the exam. The textbook he uses is awful (I've asked the TAs questions on the homework, they don't know how to do them either, and end up emailing him so that he can make it extra credit instead). Seriously.

He has his own way of teaching math, and it's not bad but it's hard to find outside help because his content isn't always traditional.

Theres a quiz at the end of every class. Tests are online but convoluted and difficult. Final is in person. Homework is easy. Doesn't teach like normal calculus. Good class but I failed the first time with a different instructor so I may just be over prepared.

I'd say he's pretty good at teaching, even if not the most energetic. Attendance technically isn't mandatory, but in-class quizzes can make or break your grade. Online exams are formatted weirdly but curve alright. He assigns some quizzes as homework but doesn't input their due dates so check class announcements for them, not the Canvas dashboard.

Mark definitely knows what he's talking about, but can be hard to understand sometimes. If you don't understand a topic the first time, he's not very good at finding another way to explain it. He means well and I can tell her wants his students to succeed, but he is sometimes condescending and lacks friendliness. Definitely find study buddies!!!

Has a well structured teaching style but what concerns me is how this feels like a different class out of the previous calc classes I had taken because often goes into too much detail and concepts get confusing as well as for the tests, he just doesn't seem to know that there are people in this class that have different learning levels.

His teaching and testing style is more conceptual over 'plug-and-chug' type questions, would highly recommend if you're prone to making mistakes during calculations but can understand concepts fundamentally still. His office hours are also very helpful before tests.

Prof. Ashbrook is definitely a professor for those who crave a challenge. His class format is unlike any of the other's in the math department, with in class (Respondus lockdown) exams. If you're not a good tester, if you're looking for a “plug and chug” professor. Do not take him! You WILL learn. GO TO HIS OFFICE HOURS! It is the reason I passed.

Ashbrook gives great lectures, and makes the concepts easy to understand. Exams are almost entirely conceptual, with exam 2 being the only notable exception. All exams are curved. If you love math and and want to understand calculus more deeply, take this class. Attendance is mandatory with quizzes after every lecture (which are very annoying).

This class was very conceptual but Mark does a good job teaching it, his lecture slides are done well with real world examples. He doesn't ever go by the book and is very disorganized at times, exams can be confusing but they're all curved, quizzes at the end of every class may seem insignificant but they'll heavily impact your grade.

Mark is a great guy and great at explaining concepts. If you go through this course, the class structure will make sure you understand Calc 2. That being said, it did feel like it was made more difficult than needed with hard questions on tests and unrelated hw problems. Very very difficult but manageable espcially if you go to TA office hours

Study your textbook and nothing else; it will only waste your time. Work on the Exercises at the end of the sections and you will probably do well. Buy an external webcam or else. I am leaving this class with a thorough concept of the rate of change, and the modules for Riemann Sums are excellent.

Prof Ashbrook is not skilled in online teaching. He offers no tools for help, was unknowledgeable about anything the university offered. When questioned regarding needing information that only he could supply regarding tutoring, he was unwilling to investigate what he needed to do. He also does not actually teach any of the lectures provided.

This class is very conceptual, not plug-and-chug. The professor mostly shows graphs and talks about theory. Tests are extremely difficult and mostly conceptual. He writes his own exams, gives poor test prep, and doesn't clearly say what's on the test. If you're not strong in conceptual thinking, this class will be tough.

Mark is very accessible outside of class. He is good at using examples to draw out definition and understanding of concepts. If you don't pay attention in class or skips classes you probably won't perform well. His tests are not the easiest, but the curve is usually pretty generous. If you are willing to put the work in in class, it's an easy A.

This class is difficult. You can get pass Calc 1 and 2 just by plugging and chugging and memorization. However, with this class, you have to understand what is happening not just remember the formulas. It seems mean in the moment, but I honestly think he wants future engineers to be great. Can seem grumpy sometimes, but does offer XC.

He's a great teacher, but he definitely makes the class harder than it needs to be. There are attendance quizzes that can make or break your grade, and the tests are entirely multiple choice with lockdown on canvas, and he makes you take them in person, which is kinda annoying, but he curves them, and they're more conceptual than plug-and-chug.

He was super awesome, always reachable, and ready to help. His lectures were not quite my style, but attendance was important due to quizzes in every lecture. Exams were online multiple-choice, focused on intuition and setup, and heavily curved. Extra credit came from written homework, early Edfinity work, and bonus quiz access-code questions.

Dude knows what he's doing. As a math major, I'm very glad I took calc 3 with Ashbrook. His class is hard and conceptual, but it forces you to learn calculus the way it should be learned. He will rebuild your intuition for rate of change and accumulation for the better. Only downside is his test format, you must have a plan during the test. Goat.

Solid professor. Seems to know his stuff about calculus and cares about teaching it. Lectures are helpful to visualize the material. There are 4 exams (3 midterms and 1 final) which are all multiple choice through lockdown browser: do not let this fool you, although they are multiple choice, they are hard, and often have a few point curve.

Professor Ashbrook makes a solid effort to get students to understand the material he is trying to teach, using visual software and reviewing concepts in ways more translatable to the real world. The test curves and extra credit are generous, but it would be good if he showed students more ways to visualize the material (Desmos, etc.)

I have a love/hate relationship with DIRACC but Ashbrook himself is good at teaching. His lessons are planned well, he cares about you understanding + he can be funny. My complaints: limited attempts on hw, lecture quizzes worth too much of your grade & tests are super tricky. But he does curve & TA's are very friendly and helpful.
