LOVED HIM! He's a super nerd but he is really funny and his tests are really easy and simple. He is super cool and fun. Def get him as a teacher if you can.

He was soooo understanding and nice. Amazing patience and really cares about his students learning.

super tough... dont take!!

Good Teacher, class moves fast, but he will help you to the best of his ability.. I recomend him as a teacher

terrible teacher. tests are really hard, and so is his grading style

Presents clear examples to questions. I actually understood math and its my worse class. Incorporates the class as a whole very often. Sometimes brings in his daughters to class (whom are adorable) and doesn't like to wear any patterned shirts. Really funny. Teaching style probably gets worse in higher level math classes.

This class is one of the hardest offered, but he makes it as bearable as it can be. He goes piece by piece into concepts to help you understand, and his outside of class help is exceptional...if you use it.

Absolutely adored this guy! He's fantastic. SO helpful. I got a 30 percent on the readiness quiz, and with his help I ended up with an A in the class. Always hated math when I was younger, and I'm so grateful that I had him. If you have to take Math 111 TAKE THIS CLASS.

I'm not sure why Hayden has gotten negative ratings - he's a really great teacher. I'm not a huge math person, but he teaches very well, answers questions, and is very fair. All homework and exams were due online. I highly recommend him to anyone.

If you do all your homework and study for the quizzes you should do fine in the class. The quizzes and homework are a lot like the midterms. If you have any questions email him or go to his office hours. The class is hard, but math is always hard. Hayden does his best to be clear and help everyone understand. He really does want everyone to pass.

Hayden is an awesome instructor, I don't care what anyone says. He wants his students to do well and gave us the opportunity to replace a midterm score with the same score as our final exam. Quizzes were tough. The only hw was webwork and exam questions were a lot like webwork problems. I would definitely sign up for his classes again.

Webwork is different from stuff we do in class. He likes to teach why instead of how. He wants his students to learn why something works. I just didn't care about why. I wanted to know how to do it, take the test, and never do math again. He's a nice fella though.

Hayden is an awesome guy with good humor. He is a fine math teacher but you really have to go to class to do well because he assigns excel homework which is impossible to complete unless you get the "codes" that he writes down in lecture. I thought math243 was pretty easy with him and i recommend him

Hayden is a great teacher with an awesome attitude. Especially for a statistics class that can be boring, he keeps the energy up. It is definitely necessary to go to class unless you are a pro at teaching yourself. Also, some of the excel based homework is hard because he doesn't teach you how to specifically use excel. But the course load is fair

Best math teacher I have ever had

Hayden did a great job teaching stats. He is funny yet descriptive in his teaching. He does a good job.

On the first day, he may seem a bit off-putting, but hes actually a really nice teacher. He wants you to pass his class, so if you are struggling he will definitely help you. Go to his office Hours, he will extend some of the homework if he knows you are trying. Somewhat hard class, with weekly homework. For a mandatory business class, its not bad

This is one of my favorite professors i've ever had. He not only has a sense of humor, but he teaches his class in the easiest way possible. His notes are clear and his homework stays true to what he teaches. Obsessed with him.

Hayden is a great calculus instructor, although with just 50 minutes for each class he sometimes has to go through a topic with only one or two examples. That said, if you have questions he is very accommodating with office hours. Exams are pretty tough, but if you know the material you will pass, its just that an A or B is going to be tough.

Cool guy and is very helpful. He attempts to make lectures interesting and is very clear when going through problems. Funny guy too

One of my favorite UO professors. Clear, simple, conversational lecture style. Very friendly and approachable. Would take this guy for any class.

Hayden is great but his tests are extremely hard. I did great on all homework but did terribly on the midterm and final. 50 min for a 4 page midterm. Barely passed.

He's slightly intimidating at first but he's an incredible teacher if you go to office hours for help and he's so willing to help even right after class. He was engaging in class and taught very well.

I am so glad that I was able to have him as my Calc prof this term. He is extremely helpful, but you will need to work to get a good grade. Lectures are very conversational and makes sure everyone understands what is going on.

A great teacher, super friendly and helpful. Go to his office hours if you have any questions, I highly recommend it. I really struggle with math, and I still passed. If you study hard and do your homework, you'll be fine. He will grade on improvement (which is how I passed :D). An awesome teacher, I wish I could take him for all my math classes.

Harker is honestly a down-to-Earth professor. He really puts time and effort into his students success. I only had him for a math lab he was teaching, but he still made me fall in love with math all over again. His lectures are extremely interesting, and beware, he can be a bit eccentric at times. He makes sure every student feels important to him!

Great professor, he let me into the class despite not technically having the prerequisites necessary to take the class. Definitely not an easy professor (lots of homework and lots of information), but he will help you if you ask for help and it's worthwhile taking his class.

Hayden is great during lectures and even better during office hours. Homework is heavy in his classes, but when it comes time to test the work load really pays off. Show up during office hours and he will gladly break it down for you. His tests are designed not to be curved, so don't expect that to save you.

I don't feel my classmates give Hayden enough credit. Hayden is an excellent instructor and he's very kind and caring. If you put in the work and the time, you will pass this class, it's not impossible. I see Hayden in office hours at least once a week and he's also given me points back on both midterms. Go see him, you can pass. Favorite teacher!

Hayden is a great teacher but that can be tough to deliver to such a big class. The tests are very hard but you will learn the content.

I was very scared going into this class because I read the ratings on Hayden beforehand. But, if you go to class, take good notes, and stay on top of your homework, it's not too hard to pass. I generally understand math so if you have always struggled with the subject then I'd suggest taking a lower level first. But don't let the ratings scare you!

Honestly, professor Hayden is a genuinely nice person. I didn't like him that much until I got to sit down and talk with him outside of class. He may seem like a terrible person in class but really isn't. I think people should go to his office hours more often. I felt really bad about saying on my evaluation that he didn't care about students.

Hayden has been the best math teacher I've had at U of O. He is down to earth and really wants his students to succeed and master the material. I would totally take a class with him again, his lectures are helpful and he has a super dry sense of humor. Overall great professor!

Though I did not do well in this class, I do not blame Hayden. He is caring, understanding and easy to reach outside of the classroom. Overall great professor, straightforward teaching style and funny too. Take his class ! But be prepared to study and work for a good grade as you would in any other course.

I liked hayden a lot. When theres an easier way to o things he explains it rather than making you do it by hand. Although the excel assignments are annoying they help buffer your grade from just tests. He takes attendance by iclicker but you get extra credit for getting answers right so you dont have to go to every class for full credit.

In spite of the difficult tests and homework, I can't help but really appreciate him. His lectures are clear and thorough, even if the tests can be surprisingly hard. I had about a 40% in the class, but since i got a C on the final, that's what he gave me--no email or anything. That meant a lot when i was going through a tough time.

Enjoy his class so much! Super funny and nice professor. He is super helpful and nice if you go to his office hour to ask him question.

This is my second time to take his class. Such a nice person.

I absolutely despise math however professor Harker made this course tolerable. He was easy to communicate with, helpful and explained things in such a way that a rarely had to refer to the textbook. Id take him again for sure.

Hayden was the best stats teacher. He was always available to answer any questions, and his office hours are super helpful. He doesn't require that we use the textbook but it does come in handy if you need further explanation.

Always helpful in office hours

I'll be honest, I think stats is a bit boring. That being said, Hayden's online lectures were great and I was able to get an A- without it being too bad at all.

Was worried about taking calculus online, but it was actually relatively easy if you do the homework and ask questions when you need help on it. Prof. Harker seems a bit intimidating, but he's really nice and is always down to help out. Live lectures were all recorded. Questions on exams & quizzes were not as difficult as the hw, & were very fair.

Hayden is a great professor! He teaches stats in a very clear and simple way that was easy to follow. He's clear on expectations, deadlines, grades, etc. He's always willing to answer questions in lecture, office hours, whenever - very helpful. Also caring about his students, he was willing to extend a deadline or get you help you need.

Professor Harker is a great professor. There are some flaws, though. If you want to pass, you must pay attention to the lectures that he posts, and he won't always help; he is more of a "read the ____ days lecture," but if you go to office hours, he helps. I found the class challenging because of the precise details that he looks for.

Class consists of pre-lecture vids (content), lecture covers examples. Open to answering questions and explains fairly well. Weekly quizzes but pretty easy bc they're similar to the weekly WS done during discussion. Covers material kind of quickly/may lack depth so refer to textbook. Tests always have a couple hard questions thrown in.

Harker is an interesting person and obviously cares about math. He lectures with specific examples and goes fairly fast. Sometimes he does not explain the "why" of what you are doing however, the nature of the large statistics course made it difficult to ask questions in class. I ended up learning a lot from going to my GEs office hours.

3 Sets of Webwork a week due on Monday,Wednesday and Friday with a weekly quiz on Fridays, and 3 exams. Very do-able as long as you pay attention. Hayden is a very interesting character, (little bit passive aggressive) but he is very caring and tries to answer everyone's questions. Very clear with his explanations. 10/10 recommend.

Very accommodating teacher and understanding about students' lives. The only time new material was taught was through Panaptos which would range from 10 to 30 minutes. His lectures were primarily just review. The tests ranged in difficulty but if you understand the WebWork you will be fine in this course.

This class was probably the easiest math class I have ever taken, I stopped going to class about halfway through and ended with an A+. Harker is very good about going through the material very diligently and also multiple times over so a great professor!

If you are taking STATS, you should really try to get Harker as your prof. I failed stats in hs due to a horrible teacher, but Harker made it so easy to understand. He explains concepts really well. He is also very organized. Would recommend!

I never thought my two hour math class would feel like 20 minutes. He is a very good speaker and is very easy to retain information from. He understands that math can be difficult and gives many opportunites to get help. I enjoy his lectures very much.

I took regular stats in HS and then AP stat my senior year. Never understood either year. Took 243 w Harker and he is honestly a great teacher. He can be kind of dry, but the people who gave him bad reviews here don't know how to take a joke. He won't give you straight up answers, but will guide you to it. SUPER patient. Take his stat class!!

At first, I was terrified of professor Harker, but he ended up being my favorite prof of the term. He's clear on what's expected of you and what you need to study outside of class. He genuinely cares about his students and is also just a cool guy. Tests are a big chunk of the grade, but he's very clear on what he expects on them. Great prof and guy

Very chill guy. Fun to be around and hard to find a reason to dislike him once you disassociate him with the horrible subject that is math. Apart from attendance he treats you like an adult which is nice, and while he has rules he isn't exactly hellbent on babysitting adults. Definitely a good teacher for math101 at the very least.

I don't care about what people say about professor Harker, he was fantastic. Keeping in mind this is a really hard class, if you listen and participate, and do the HW, you will pass. Favorite math professor I've had.

Great teacher if you show up and put in the effort. Skipping lectures will put you behind but the grading is pretty generous. There where 4 tests with the lowest one being dropped WebWork, and attendance can count for extra credit.

I want to start by saying I am NOT a math person. But I feel Harker does a really good job of providing as many opportunities for students as he can to help boost their grade. Only 2/3 exams count towards your grade, 2 lowest quizzes dropped, only 90% of webwork needs to be completed to get a 100% and the rest counts as EC. Go the encore sessions!

Textbook is a free download online. You don't even need to attend the lectures if you read the textbook. Webwork 2-3x/week and a Friday quiz every week. Only 90% of Webwork needs to be completed, the rest is EC. 2 midterms and a final, two highest scores get taken. Two lowest quiz scores dropped as well. I didn't even have to take the final.

Great teacher and provides lots of resources to help boost your grade. He definitely can be intimidating and sassy, he is a bit eccentric, but he wants the best for his students and he is very helpful when you are struggling.

Professor Harker was definitely my favorite professor this term. He was excited to teach every day, answered questions thoroughly, and explained concepts well. As long as you do the homework and come to class, you'll do good. He is also very accessible outside of class. Overall, amazing guy and a great teacher.

Hayden was one of the best professors I have had for math. If you have the opportunity to take his stats class do so. If you pass the two midterms you don't have to take the final. He explains everything very well.

Hayden is not a mean person but can come off that way to some people. He's a very straight to the point person and moves on to the next topic. He can be pretty speedy when he goes through content in his lectures. But as long as you keep up with the homework and pay attention, you should be fine for the exams.

Think of the definition of a "goofball" or "silly duck". That's this guy. He is actually really good at teaching; he keeps his lectures very easy to understand without crowding them with a ton of BS. Going to his office hours feels unpleasant; he will yell at you, asking why on God's green earth would you not understand the material. Good teacher.

Chill guy but lots of the homework covers material you haven't learned yet so you need to teach yourself

Hayden is much better than the rating he has been given by some students. He does not require attendance but you definitely need to go to class if you want to fully understand the material. He does use excel a decent amount as others have said but he also shows you how to do the same stuff without excel which I think is pretty fair. rate 7/10

This professor is amazing and very wise!! He goes a little fast, but he explains things well and is easy to understand if you can keep up. I took, Statistics in high school and did not understand much, but I finally got clarity on many many topics from him!!

Hayden is a funny guy. His STAT243Z class was super easy.

Hayden was a great professor if you're willing to put in the work to practice the concepts outside of class. He does a great job in class of explaining the concepts and how to do the problems, but there aren't many example problems. So, it is important you work hard on the homework because the tests are almost example the same as the homework.

Really knowledgable and one of the best math professors you'll find

Great professor if you are willing to actually show up and put in effort. His lectures were a little boring, and he didn't have many examples, so it's important to study outside of class. His tests are difficult and a little long, but very similar to the examples in his lectures and hw. Overall, a funny guy and a good teacher.

Hayden is a funny guy with lectures that always entertain me. Definitely take advantage of office hours and email. He's pretty lenient and drops a lot of grades at the end of the class. Timed quizzes once a week and written portions of midterms absolutely require studying, especially the 2nd one.

Me and my friends loved Hayden he's a great professor you MUST attend lectures to understand the class the only downside to Haydens class is his posted lecture slides make no sense unless you attend the class. If you just pay attention write notes and study you can pass. Use E-book to help study and find study groups makes it a lot easier.

Show up to class if you want to pass this class. Hayden is a really funny teacher who explains stats concepts pretty well. The project and test criteria are layed out clearly if you are in class. Some of the lecture content is difficult to digest by the lecture alone and I had to spend a lot of time reviewing outside class. Lots of online homework.
